`
`BACKGROUND OF THE INVENTION
`
`Field of the Invention
`
`The present
`
`invention relates
`
`to mobile
`
`communication
`
`technology,
`
`and
`
`more
`
`particularly,
`
`to
`
`technology
`
`of
`
`transmitting’
`
`uplink.
`
`signals
`
`including
`
`ACK/NACK
`
`signals,
`
`control
`
`signals other
`
`than the ACK/NACK signals,
`
`and data
`
`signals.
`
`Discussion of the Related Art
`
`A user equipment
`
`
`(UE) of
`
`a Umbile communication system
`
`transmits ‘various signals through an uplink. Uplink signals
`
`transmitted by the user equipment can be segmented into data

`Huawei v. OPTIS Exhibit No. 1002 - 4/401
`
`

`

`Attorney Docket No. 2101—3573
`
`signals and control
`
`signals. Also,
`
`examples of
`
`the control
`
`signals
`
`transmitted to the uplink include uplink ACK/NACK
`
`signals
`
`for
`
`HARQ
`
`communication,
`
`channel quality indicator
`
`(CQI)
`
`information, and precoding matrix index (PMI).
`
`3GPP LTE system uses a single carrier frequency division
`
`multiplexing
`
`access
`
`(SC—FDMA)
`
`scheme
`
`for
`
`uplink
`
`signal
`
`transmission. Also,
`
`the 3GP? LTE system prescribes that data
`
`signals and control signals among the uplink signals are first
`
`multiplexed and ACK/NACK
`
`signals
`
`are
`
`transmitted to
`
`the
`
`multiplexed signals by puncturing the data or control signals
`
`when uplink ACK/NACK signal
`
`transmission is
`
`required for
`
`downlink data. Hereinafter,
`
`in order that the ACK/NACK signals
`
`are divided from control
`
`signals other
`
`than the ACK/NACK
`
`signals,
`
`the control signals will mean those except
`
`for
`
`the
`
`ACK/NACK signals.
`
`Meanwhile, Athens
`
`conference
`
`(#50)
`
`for
`
`3GPP
`
`LTE has
`
`decided that data information is rate Hatched together with
`
`control
`
`information
`
`when
`
`the
`
`control
`
`information
`
`is
`
`multiplexed with the data information, wherein the control
`
`information is transmitted near a reference signal. This is to
`
`improve channel estimation performance by’ approximating zall
`
`the control signals to the reference signal as
`
`the control
`
`signals generally’
`
`require higher
`
`reliability'
`
`than the data
`
`signals.
`
`However,
`
`the control signals transmitted to the uplink
`
`Huawei v. OPTIS Exhibit No. 1002 - 5/401
`
`

`

`Attorney Docket No. 2101-3573
`
`include various signals as described above,
`
`and the ACK/NACK
`
`signals
`
`require higher
`
`reliability than the other control
`
`signals.
`
`In
`
`this
`
`case,
`
`when
`
`uplink
`
`ACK/NACK
`
`signal
`
`transmission.
`
`is required while all
`
`the control signals are
`
`transmitted by approximating to the reference signal, problems
`
`occur in that
`
`the ACK/NACK signals can neither be transmitted
`
`by puncturing the control signals arranged near the reference
`
`signal nor be transmitted near the reference signal.
`
`In this respect,
`
`a
`
`technology of
`
`transmitting uplink
`
`signals by’ efficiently' arranging‘ ACK/NACK signals and. other
`
`control
`
`signals
`
`in a
`
`resource region considering priority
`
`among them is required.
`
`SUMMARY OF THE INVENTION
`
`Accordingly,
`
`the present
`
`invention is directed to a
`
`method.
`
`for
`
`transmitting’ uplink signals, which. substantially
`
`obviates
`
`one
`
`or more
`
`problems
`
`due
`
`to
`
`limitations
`
`and
`
`disadvantages of the related art.
`
`An object of
`
`the present
`
`invention.
`
`is
`

`a
`
`method.
`
`for
`
`transmitting'
`
`uplink
`
`signals
`
`by
`
`efficiently
`
`arranging ACK/NACK signals
`
`and other control
`
`signals
`
`in a
`
`resource region considering priority among them.
`

`
`arrangement.
`
`To achieve these objects
`
`and other advantages
`
`and in
`
`accordance with the purpose of
`
`the invention, as embodied and
`
`broadly described herein,
`
`the present
`
`invention. provides
`
`a
`
`method for transmitting uplink signals, which include ACK/NACK
`
`signals, control signals other than the ACK/NACK signals, and
`
`data signals. The method comprises serially wmltiplexing the
`
`control signals and the data signals; sequentially mapping the
`
`multiplexed signals within a
`
`specific resource
`
`region in
`
`accordance with a
`
`time»first mapping method,
`
`the
`
`specific
`
`resource
`
`region including a plurality of
`
`symbols
`
`and
`
`a
`
`plurality of virtual subcarriers;
`
`and arranging the ACK/NACK
`
`signals at both symbols near
`
`to symbols
`
`through which a
`
`reference signal is transmitted.
`
`At
`
`this time,
`
`the ACK/NACK signals are overwritten on a
`
`part
`
`of
`
`the multiplexed signals. And,
`
`the part
`
`of
`
`the
`
`multiplexed
`
`signals,
`
`on which
`
`the
`
`ACK/NACK
`
`signals
`
`are
`
`overwritten,
`
`includes one or more of
`
`the control signals and
`
`the data signals.
`
`Also,
`
`the method further comprises performing a discrete
`
`fourier transform (DPT)
`
`for the signals mapped on the specific
`
`
`resource region in a unit of each symbols of
`
`the plurality of
`
`symbols

`in accordance with.
`
`each.
`
`index of
`
`the plurality of
`
`virtual
`
`subcarriers;
`
`performing
`
`an
`
`inverse
`
`fast
`
`fourier
`
`transform (IFFT)
`
`for the DFT symbol unit signals and attaching
`
`Huawei v. OPTIS Exhibit No. 1002 - 7/401
`
`

`

`Attorney Docket No. 2101~3573
`
`a cyclic prefix (CP)
`
`the signals; and transmitting the symbol
`
`
`unit signals attached with the CP as single carrier frequency
`
`division multiplexing access (SC—FDMA) symbols.
`
`Also,
`
`the method
`
`further
`
`comprises
`
`transmitting the
`
`signals mapped
`
`on
`
`the
`
`specific resource
`
`region through a
`
`physical uplink sharing channel
`
`(PUSCH).
`
`In another aspect of
`
`the present
`
`invention,
`
`the present
`
`invention provides a method for transmitting uplink signals,
`
`which include ACK/NACK signals, control signals other than the
`
`ACK/NACK signals,
`
`and data
`
`signals.
`
`The method
`
`comprises
`
`performing channel coding for each of
`
`the data signals,
`
`the
`
`control
`
`signals,
`
`and
`
`the
`
`ACK/NACK
`
`signals;
`
`serially
`
`multiplexing the
`
`channel
`
`coded data
`
`and
`
`control
`
`signals;
`
`sequentially* mapping the multiplexed signals
`
`in accordance
`
`with a
`
`time—first mapping method within a specific resource
`
`region.
`
`in accordance with,
`
`a
`
`time—first mapping' method,
`
`the
`
`
`specific resource region including a plurality of symbols and
`
`a plurality of virtual subcarriers; and arranging the ACK/NACK
`
`signals at both symbols near
`
`to the symbols
`
`through which a
`
`reference signal is transmitted.
`
`At
`
`this time,
`
`the step of performing channel coding for
`
`the data signals
`
`includes attaching'
`
`a CRC
`
`for
`
`a
`
`transport
`
`block (TB)
`
`to a transport block for transmission of
`
`the data
`
`signals;
`
`segmenting the transport block attached with the CRC
`
`for the transport block in a code block unit and attaching a
`
`Huawei v. OPTIS Exhibit No. 1002 - 8/401
`
`

`

`Attorney Docket No. 2101—3573
`
`CRC for a code block to the segmented code block; performing
`
`channel coding for the data attached with the CRC for a code
`
`block;
`
`and
`
`performing
`
`rate matching
`
`and
`
`code
`
`block
`
`concatenation for the channel coded data.
`
`According
`
`to
`
`the
`
`aforementioned
`
`embodiments
`
`of
`
`the
`
`present
`
`invention,
`
`it is possible to transmit uplink signals
`
`by efficiently arranging ACK/NACK signals and other control
`
`signals in a resource region in accordance with priority among
`
`them.
`
`In addition,
`
`the ACK/NACK signals having high priority
`
`can be set
`
`in such a manner
`
`that
`
`they acquire more channel
`
`
`estimation effect.

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`Hereinafter,
`
`the preferred embodiments of
`
`the present
`
`invention will be described with reference to the accompanying
`
`drawings.
`
`It is to be understood that the detailed description,
`
`which will be disclosed along with the accompanying drawings,
`
`is
`
`intended to describe
`
`the
`
`exemplary embodiments of
`
`the
`
`present
`
`invention,
`
`and is not
`
`intended to describe a unique
`
`embodiment with which the present
`
`invention can be carried out.
`
`Hereinafter,
`
`the
`
`following detailed description
`
`includes
`
`detailed matters to provide full understanding of
`
`the present
`
`invention. However,
`
`it will be apparent
`
`to those skilled in
`
`the art
`
`that
`
`the present
`
`invention can be carried out without
`
`the detailed matters.
`
`Meanwhile,
`
`in some cases,
`
`to prevent
`
`the concept of
`
`the
`
`present
`
`invention
`
`from being
`
`ambiguous,
`
`structures
`
`and
`
`apparatuses of the known art will be omitted, or will be shown
`
`in the form of a block diagram based on main functions of each
`
`structure and apparatus. Also, wherever possible,
`
`the same
`
`reference numbers will be used throughout
`
`the drawings and the
`
`specification to refer to the same or like parts.
`
`As described above,
`
`the
`
`embodiment
`
`of
`
`the present
`
`invention.
`
`is intended.
`
`to provide a method.
`
`for
`
`transmitting
`
`uplink signals by efficiently arranging ACK/NACK signals and

`
`in
`
`a

`
`region
`
`considering
`
`priority'
`
`among
`
`them.
`
`To
`
`this
`
`end,
`
`a detailed method
`
`for
`
`transmitting uplink signals
`
`in a
`
`3GPP
`
`LTE
`
`system will be
`
`described.

`

`
`a single carrier frequency division multiplexing access
`
`(SC—
`
`FDMA)
`
`scheme.
`
`As described above,
`
`a 3GP? LTE system transmits uplink
`
`signals in accordance with a single carrier frequency division
`
`multiplexing‘ access
`
`(SC-FDMA)
`
`scheme.
`
`In. detail,
`
`direct—to—
`
`parallel conversion is performed for information sequences to
`
`be transmitted,
`
`to perform a discrete fourier transform (DFT)
`
`(101). The DFT is performed for the signals converted to the
`
`parallel
`
`sequences
`
`(102),
`
`and
`
`then
`
`inverse
`
`fast
`
`fourier
`
`transform (IFFT)
`
`can be performed to obtain a single carrier
`
`feature (103). At
`
`this time,
`
`a length of
`
`information inserted
`
`to an IFFT module 103 may not be equal
`
`to a size of
`
`the IFFT
`
`module
`
`103. However,
`
`it
`
`is
`
`required that
`
`the DFT
`
`result
`
`performed
`
`by
`
`the
`
`
`DFT module
`
`102
`
`should be mapped with
`
`continuous IFFT input
`
`indexes.
`
`Values undergone
`
`IFFT are again converted to serial
`
`signals
`
`by
`
`a
`
`parallel—to—serial
`
`conversion module
`
`104.
`
`Afterwards,
`
`the
`
`signals
`
`are
`
`changed to a
`
`format of
`
`OFDM
`
`symbols by a cyclic prefix (CP)
`
`(105) and then transmitted to
`
`10
`
`Huawei V. OPTIS Exhibit No. 1002 - 12/401
`
`

`

`Attorney Docket No. 2101'3573
`
`a real time space.
`
`The aforementioned SC-FDMA scheme has advantages in that
`
`it has
`
`low peak power—to—average power
`
`ratio (PAPR)
`
`and/or
`
`cubic metric (CM) while maintaining a single carrier feature.
`
`However,
`
`in order
`
`to satisfy low PAPR/CM condition while
`
`maintaining a
`
`single carrier
`
`feature,
`
`it
`
`is required that
`
`information. undergone DFT‘ precoding should be
`
`input
`
`to the
`
`IFFT module 103 in an OFDM format by mapping with continuous
`
`indexes.
`
`In other words,
`
`it
`
`is required that DPT precoded
`
`information.
`
`should. be inserted.
`
`to continuous subcarriers of
`
`OFDM. Accordingly, it is preferable that information data (for
`
`example,
`
`control
`
`information and data
`
`information)
`
`having
`
`different
`
`features are multiplexed together when
`
`they are
`
`transmitted to an uplink so that
`
`they undergo DFT precoding
`
`together and then are transmitted in an OFDM format.
`
`Hereinafter,

`
`and

`ACK/NACK signals for uplink signal transmission.
`
`Data information multiplexed with control
`
`information is
`
`segmented into several code blocks
`
`(CE)
`
`in accordance with a
`
`size of a transport block (TB)
`
`to be transmitted to the uplink
`
`after
`
`CRC
`
`for
`
`TB is attached.
`
`to the TE
`
`(8201 and $202).
`
`Afterwards,
`
`the CRC for CB is attached to several CBs
`
`(8203),

`ll

`
`and channel coding is performed for the result value obtained
`
`by attaching the CRC for CB to several CBs
`
`(S204). Also, after
`
`the
`
`channel
`
`coded
`
`data
`
`undergo
`
`rate matching
`
`(8205),
`
`concatenation among CBs
`
`is performed (8206). The CBs are then
`
`multiplexed, with. control
`
`information,
`
`(8230). Meanwhile,
`
`the
`
`aforementioned steps may be subject
`
`to channel coding chain
`
`for a data transport block.
`
`Channel
`
`coding
`
`can
`
`be
`
`performed
`
`for
`
`the
`
`control
`
`information separately from the data information (8211). The
`
`channel
`
`coded, control
`
`information,
`
`can later be multiplexed
`
`with the data information by a data and control channel rate
`
`mapping multiplexer (8230).
`
`Channel coding can be performed for the ACK/NACK signals
`
`separately from the data and control signals
`
`(8221). Some of
`
`the uplink signals in which the data and control signals are
`
`multiplexed (S230) may be transmitted to the uplink through
`
`puncturing (S240).
`
`As described above,
`
`the control
`
`information that can be
`
`transmitted‘
`
`together‘ with.
`
`the data information.
`
`is segmented
`
`into two
`
`types,
`
`i.e.,
`
`uplink
`
`(UL)
`
`ACK/NACK signals
`
`for
`
`downlink data and other control
`
`information.
`
`The uplink
`
`ACK/NACK signals for downlink data are transmitted only when
`
`downlink data exist. A user equipment may not know whether to
`
`receive downlink data even though it should transmit
`
`the UL
`
`ACK/NACK signals. Accordingly,
`
`the user equipment segments the
`
`12
`
`Huawei V. OPTIS Exhibit No. 1002 - 14/401
`
`

`

`
`Attorney Docket No. 2101—3573
`
`two types of control
`
`information from each other and transmits
`
`them to
`
`the uplink together with the data
`
`information.
`
`Hereinafter,
`
`in order to segment
`
`the ACK/NACK signals from the
`
`control
`
`signals
`
`transmitted separately from the ACK/NACK
`
`signals,
`
`“control
`
`signals” will mean.
`
`those other
`
`than the
`
`ACK/NACK signals.
`
`In. more detailed embodiment,
`
`the control
`
`signals may mean those other than a rank indicator as well as
`
`the ACK/NACK signals.
`
`In other words,
`
`in a specific embodiment,
`
`the control signals may include CQI and PMI. However,
`
`since
`
`the
`
`following description relates
`
`to efficient
`
`arrangement
`
`among the control signals,
`
`the data signals and the ACK/NACK
`
`signals,
`
`if
`
`the control
`
`signals are those other
`
`than the
`
`ACK/NACK signals,
`
`their detailed type will not be suggested.
`
`when the data information is transmitted to the uplink,
`
`the data information.
`
`can be
`
`transmitted together with the
`
`control
`
`information. Also,
`
`ACK/NACK
`
`information
`
`can
`
`be
`
`transmitted together with the data information and the control
`
`information. Moreover,
`
`only the data
`
`information and
`
`the
`
`ACK/NACK information can be transmitted to the uplink.
`
`Transmission information sequences obtained to transmit
`
`the data information multiplexed with the control
`
`information
`
`or
`
`the ACK/NACK information can be transmitted in accordance
`
`with
`
`the
`
`SC—FDMA
`
`scheme. At
`
`this
`
`time,
`
`the
`
`transmission
`
`information sequences can be mapped in a
`
`resource region in
`
`accordance with a time—first mapping method.

`
`For
`
`example,
`
`it
`
`is
`
`supposed
`
`that
`
`the
`
`information
`
`sequences
`
`are
`
`transmitted using one
`
`resource block,
`
`i.e.,
`
`twelve
`
`(12)
`
`OFDM subcarriers and.
`
`information.
`
`is transmitted
`
`through one sub~frame. Also, it is supposed that one sub'frame
`
`includes fourteen (14)
`
`
`SC—FDMA symbols and two of the fourteen
`
`SC—FDMS symbols are used as references signals that are pilot
`
`signals. At this time,
`
`the number of modulation symbols of the
`
`information.
`
`that
`
`can be
`
`transmitted,
`
`to the uplink becomes
`
`12*122144.
`
`144
`
`information sequence
`
`symbols
`
`can
`
`be
`
`transmitted
`
`through 12 virtual subcarriers and 12
`
`SC~FDMA symbols. This
`
`can be represented by a matrix structure of 12*12 called a
`
`time—frequency mapper.
`
`The
`
`information
`
`sequences
`
`to
`
`be
`
`transmitted to the uplink are mapped one by one based on the
`
`SC-FDMA symbols. This is called time~first mapping because the
`
`SC—FDMA symbols are segmented temporally.

`
`The
`
`information sequences
`
`to be
`
`transmitted to the
`
`uplink can be arranged temporally in the time~frequency mapper

`
`as illustrated in FIG. 3.
`
`In other words,
`
`12 information data
`
`are mapped temporally 511 a first virtual subcarrier region,
`
`and then subsequent 12 information data are mapped temporally
`
`in a second virtual subcarrier region.
`
`After time-frequency mapping is performed as above,
`
`the
`
`sequences arranged on a frequency axis as illustrated in FIG.
`

`
`5 undergo DFT and then are inserted to a desired
`
`frequency
`
`band. Afterwards,
`
`IFFT
`
`and
`
`CP
`
`insertion are
`
`performed for each frequency region information, which can be
`
`transmitted as SC~FDMA symbols. FIG.
`
`4 and FIG.
`
`5 illustrate a
`
`procedure of generating and transmitting the SC—FDMA symbols.

`
`the control
`
`information can also be transmitted thereto. At this time,
`
`the
`
`control
`
`information and the data information are multiplexed
`
`through rate matching. However,
`
`the ACK/NACK information can
`
`be transmitted in such a manner that it is overwritten in bit
`

`
`of
`
`the
`
`data
`
`information
`
`or
`
`symbols where
`
`data
`
`information and control
`
`information are nmltiplexed.
`
`In this
`
`case, “overwritten" means
`
`that specific information mapped in
`
`the resource region is skipped and the corresponding region is
`
`mapped. Also,
`
`“overwritten” means
`
`that
`
`the
`
`length of
`
`the
`
`entire information is maintained equally even after specific
`
`information.

`
`Generally,
`
`the

`
`To
`
`this
`

`
`the
`

`
`
`in this case,

`
`In detail, when the number of ACK/NACK information data
`
`to be transmitted is more than the number of subcarriers (of a
`
`virtual frequency region)
`
`to which data are transmitted before
`
`and after the reference signal,
`
`the ACK/NACK information can

`
`considering this,
`
`the
`
`ACK/NACK information should be inserted by puncturing.
`
`When
`
`the control
`

`
`the
`
`control
`
`
`information and
`
`the data

`information are arranged in due order so that
`
`they are mapped
`
`in the resource region. Also,
`
`if the ACK/NACK information is
`
`arranged near
`
`the reference signal,
`
`the ACK/NACK information
`
`can be overwritten in the control

`
`According

`to
`
`this
`

`
`so that
`
`the control

`
`in this embodiment,
`
`it is supposed

`control
`
`information. At this time,
`
`the control

`multiplexed.
`
`The
`
`ACK/NACK
`
`
`information
`
`punctures
`
`the
`
`data/control information located near the reference signal.
`
`In detail, a reference numeral 901 of FIG.
`

`
`that
`
`the data and control
`
`signals are multiplexed if
`
`the
`
`ACK/NACK signals need not
`
`to be
`
`transmitted.
`
`A reference
`
`numeral 902 of FIG.
`
`9
`
`illustrates that data, control signals
`
`and ACK/NACK signals are nmltiplexed if the ACK/NACK signals
`
`(1
`should be transmitted. Also, a reference numeral 903 of Flw.
`
`9
`
`illustrates that
`
`the multiplexed uplink signals are mapped in
`
`the
`
`time~frequency region as
`
`illustrated in the
`
`reference
`
`numeral 902.
`
`As
`
`illustrated in the reference numeral 903 of FIG.
`
`9,
`
`it is noted from this embodiment that the ACK/NACK signals can
`
`puncture the control signals as well as the data matched near
`
`the reference signal.
`
`In.
`
`this way,
`
`if
`
`resource mapping is
`
`performed by‘ giving priority to the control
`
`signals,
`
`good
`
`channel estimation effect
`
`can. be obtained as
`
`the ACK/NACK
`
`information is located near the reference signal. On the other
`
`hand, since a small number of control signals are punctured by
`
`the ACK/NACK signals,
`
`it may not affect performance.
`
`In one
`
`embodiment
`
`shown in FIG. 9,
`
`the ACK/NACK signals may puncture
`
`the control signals/data. equally‘ distributed.
`
`in the 'virtual
`
`frequency axis. That is,
`
`if the number of virtual subcarriers

`
`

`

`Attorney Docket No. 2101-3573
`
`available for the above puncturing by the ACK/NACK signals is
`
`“N” and the number of ACK/NACK to be transmitted per SC—FDMA
`
`symbol
`
`is “m”,
`
`the ACK/NACK signals may puncture the control
`
`signals/data equally distributed having the interval of
`
`“N/m”
`
`or equivalent.
`
`Also,
`
`since
`
`the
`
`control
`
`information
`
`and
`
`the
`
`data
`
`information are multiplexed simply,
`
`a nmltiplexing block can
`
`be formed simply.
`
`Hereinafter,
`
`a whole procedure of
`
`transmitting uplink
`
`
`signals in accordance with the aforementioned embodiments of
`
`the present
`
`invention will be described. For convenience of
`
`description,
`
`this procedure will be described with reference
`
`to FIG. 2.
`
`In order
`
`to transmit
`
`the uplink signals in accordance
`
`with.
`
`each. of
`
`the embodiments of
`
`the present
`
`invention,
`
`the
`
`transmitter performs channel coding for each of data signals,
`
`control signals, and ACK/NACK signals. Channel coding for each
`
`of
`
`the uplink signals
`
`can be performed
`
`independently as
`
`illustrated in FIG. 2.
`
`At this time, as illustrated in FIG. 2,
`
`the procedure of
`
`performing' channel
`
`coding~ for
`
`the data signals can include
`
`steps of segmenting a TB attached with CRC for TB in a unit of
`
`CB (8202), attaching a CRC for CB to the segmented CBS
`
`(8203),
`
`performing channel coding for the data attached with the CRC
`
`for CE
`
`(8204), performing rate matching for the channel coded
