`
`Technical Field
`
`The present
`
`invention relates to a
`
`transmission
`
`apparatusandtransmissionmethodwhichtransmitssignals
`
`
`from a plurality of transmission antennas like an MZMO
`
`(Multi—Input/Multi—Output) communication and adopts a
`
`
` CDMA (Code Division Multiple Access)
`
`scheme.
`
`Background Art
`
`AnJMIMO (Multi-Input,/Multi~Output) communication
`
`is attracting attention as a
`
`technology for realizing
`
`communications of large~volume data such as images in
`
`recentyears.
`
`IntheMIMOcommunication,differentitems
`
`of transmission data (substreams) are transmitted from
`
`a plurality of antennas on a transmitting side and the
`
`plurality of
`
`items of transmission data mixed along a
`
`propagation path is separated into the original
`
`items
`
`of transmission data on a receiving side using a
`
`propagation_path estimated value (e.g., see FIG.4 in the
`
`Unexamined Japanese Patent Publication No.2002—44051).

`
`the same number of antennas as transmission apparatuses
`
`and characteristics of propagation paths between the
`
`antennas are estimated based on pilot signals inserted

`
`for example,

`there are two antennas on the transmitting
`
`side and two reception antennas,

`
`In the MIMO communication,
`
`transmission signals transmitted from the respective
`
`transmission antennas are obtained based on an inverse
`
`matrix of this propagation path characteristic H and
`
`received signals obtained from.the respective reception
`
`antennas.
`
`Thus,

`
`In order to prevent deterioration of the error rate

`104—1, 104-2,
`
`transmission sections 105—1, 105—2,
`
`antennas 106—1, 106—2,
`
`a spreading control section 107
`
`and a control section 110. Of these sections, suppose
`
`thesectionsfromthespreadingsections102totheantenna
`
`106—1 are collectively called a “first transmission
`
`system” while the sections from the spreading sections

`103toiflu3antenna106-2 arecollectivelycalledea“second
`
`transmission system.”
`
`In FIG.1,

`
`outputs the transmission signal
`
`to the S/P conversion

`conversionsection11H.andspreadingcontrol section107
`
`according to a retransmission flag notified from a
`
`reception section (not shown) which has received a
`
`retransmission request from the receiving side.
`
`A more
`
`specific operation of the control section 110 will be
`
`explained later.
`
`The 8/? conversion section 101 converts the
`
`transmission signal output from_the control section 110
`
`to parallel data separated for each transmission system
`
`and outputs the parallel data to their corresponding
`
`spreading sectionleZ—l tolOZ—N’andspreading sections
`
`103—1 to 103—N.
`
`In the case of the spreading section 102,
`
`the
`
`spreading sections 102—1 to 102—N corresponding to the
`
`respective parallel data output from the S/P conversion
`
`section 101 carry out spreading processing on the
`
`respectivedataunderthecontrolofthespreadingcontrol
`
`section 107 and output the spread data to the addition
`
`section 104-1. Likewise,
`
`in the case of the spreading
`
`section 103,
`
`the spreading sections 103-1 to 103—N
`
`correspondimgtotherespectiveparalleldataoutputfrom
`
`the S/P conversion section 101 carry out spreading
`
`processing on the respective data under the control of

`
`the spreading control section 107 and output the spread
`
`25
`
`data to the addition section 104—2.
`
`The addition sections 104—1,
`
`104—2 add up
`
`(multiplex) the parallel data output from_the respective
`
`spreading sections 102, 103 and output

`

`

`results to the transmission sections 105—1,
`
`105—2.
`
`The transmission sections 105—1,
`
`105—2 carry out
`
`predetermined radio transmission processing such as
`
`up—conversion, etc., on the multiplexed signals output
`
`from the addition sections 104—1,
`
`104—2 and send this
`
`data through the antennas 106—1,
`
`106—2 by radio.
`
`FIG.2 is a block diagram showing the main internal
`
`configuration of the control section 110.
`
`The control
`
`section 110 includes a data recognition section 111,
`
`a
`
`10
`
`buffer 112 and a retransmission control section 113.
`
`Thedatarecognitionsection111recognizesthetype
`
`of data included in the transmission signal based on the
`
`channel quality and moving speed on the receiving side
`
`output
`
`from the channel quality measuring section and
`
`moving speed measuring section (both are not shown) and
`
`then writes the transmission signal
`
`in the buffer 112.
`
`Furthermore,
`
`the data recognition section 111 outputs
`
`the control signal C1 to the S/P conversion section 101
`
`and spreading control section 107 according to the
`
`recognized type of data.
`
`The retransmission control
`
`section 113 outputs the control signal C2
`
`to the S/P
`
`conversion section 101 and buffer 112 according to the
`
`retransmission flag notified from.the reception section
`
`(not shown) which has received a retransmission request
`
`from the receiving side.
`
`The buffer 112 outputs the
`
`buffered data to the 8/? conversion section 101 based
`
`on the control signal C2 output from.the retransmission
`
`control section 113.

`

`

`Next,
`
`the operation of the CDMA transmission
`
`apparatus in the above described configuration will be
`
`explained.
`
`The recognition processing on the above described
`
`type of data carried out by the data recognition section
`
`
`111 refers to processing of recognizing and
`
`distinguishing data to which the CDMA transmission
`
`apparatus according to this embodiment gives higher
`
`priority in transmission (hereinafter referred to as
`
`10
`
`
`“specificdata”)fromotherdata. Here,thespecificdata
`
`more specifically refers to a control signal for
`
`controlling a communication with the receiving side or
`
`data to be transmitted now to the receiving side having
`
`poor channel quality (channel quality ofaipredetermined
`
`level or
`
`lower) or the receiving side having a higher
`
`moving speed (moving speed of a predetermined level or
`
`higher).
`
`The data recognition section 111 notifies the
`
`3/? conversion section 101 and spreading control section
`
`107 of specific data information indicating which data
`
`is specific data using the control signal C1.
`
`The specific data also includes data whose
`
`retransmission is requested by the receiving side
`
`(retransmission data) or data having a
`
`large
`
`retransmission count (retransmission count is equal to
`
`orhigherthanarmedeterminedcount). Thespecificdata
`
`is notified by the retransmission control section 113
`
`to the S/P conversion section 101 and spreading control
`
`section 107 using the control signal C2.

`
`

`

`The S/P conversion section 101 apportions the
`
`transmission data output
`
`from the control section 110
`
`to the spreading sections 102—1 to 102—N, 103—1 to 103—N
`
`based on the specific data information notified by the
`
`control signals C1, C2. When the transmission data is
`
`notspecificdatakxn;dataindicatingsimpleinformation,
`
`the transmission data is apportioned substantially
`
`equally to the respective spreading sections to improve
`
`thetransmissionefficiency. Onthecfljmnfhand,whenthe
`
`transmission data is specific data,
`
`this data is read
`
`from the buffer 112 at least twice and this data is
`
`apportioned so as to be transmitted using both of the
`
`firsttransmissionsystemandsecondtransmissionsystem
`
`or more transmission systems (at least two transmission
`
`systems when there are three or more transmission
`
`systems).
`
`The spreading control section 107 controls the
`
`spreading sections 102,
`
`103 using a control signal C3
`
`so that the specific data apportioned to the first
`
`transmission system and second transmission system is
`
`spread/modulated using different spreading codes
`
`(differing between the first transmission system and
`
`second transmission system).
`
`The specific data and other data spread/modulated
`
`by the respective spreading sections are multiplexed by
`
`the addition sections 104—1, 104—2 for each transmission
`
`systeHLand transmittedkulradio through the transmission
`
`sections 105—1, 105~2 and antennas 106—1, 106-2.

`
`FIG.3 illustrates an example of the configuration
`
`of a transmission signal of the CDMA transmission
`
`apparatus according to this embodiment. Here,
`
`a case
`
`where the specific data is retransmission data will be
`
`explained as an example.
`
`As shown in this figure, data 1 transmitted at a
`
`first transmission timing is data directed to user 1 to
`
`user 2N and the data 1 directed to user 1
`
`to user N is
`
`transmitted from_the first transmission system (antenna
`
`1), while the data 1 directed to user (N+l)
`
`to user 2N
`
`is transmitted from the second transmission system
`
`(antenna 2).
`
`The above described data is not specific
`
`data.
`
`On the other hand,
`
`retransmission data is also
`
`transmitted accompanying the data 1. This
`
`retransmission datajjsspecific data, apportionedimathe
`
`firsttransmissionsystemandsecondtransmissionsystem
`
`based on the configuration of the CDMA transmission
`
`apparatus according to this embodiment and
`
`spread/modulatedlising different spreading codes. Data
`
`2 which is transmitted at the next transmission timing
`
`also has the same configuration as that of the data 1
`
`as shown in the figure.
`
`FIG.4 illustrates another example of the
`
`configuration of a
`
`transmission signal of the CDMA
`
`transmission apparatus according to this embodiment.
`
`Here,
`
`a case where the data 1 directed to user 1 to user
`
`N and the data 2
`
`likewise directed to user 1
`
`to user N
`
`are transmitted simultaneously at a first transmission

`

`ll
`
`timing using the first transmission system (antenna 1)
`
`andsecondtransmissionsystem(antenna2). Aswiththe
`
`case described above, the data is not specific data.
`
`On
`
`the other hand, retransmission data is also transmitted
`
`accompanying the data]_and data 2. This retransmission
`
`data is specific data, apportioned to the first
`
`transmissionsystemandsecondtransmissionsystmnbased
`
`on the configuration_of the CDMA transmission apparatus
`
`according to this embodiment and spread/modulated using
`
`different spreading codes.
`
`The data transmitted at the
`
`next transmission timing is data directed to user (N+l)
`
`to user 2N as shown in the figure.
`
`FIG.5 illustrates an example of the configuration
`
`of a signal
`
`transmitted by a conventional CDMA
`
`transmissionapparatusundertimesameconditionsettings
`
`as those described above.
`
`For example, when an
`
`interference compensation error occurs in a signal
`
`transmitted from the antenna 1,
`
`retransmission data
`
`results in a reception error, and therefore the
`
`transmitting side further repeats retransmission, which
`
`deteriorates the transmission efficiency of the
`
`communication system.
`
`Asexplainedabove,theCDMAtransmissionapparatus
`
`according to this embodiment uses two transmission
`
`systems to transmit different items of data, and thus
`
`maintains high transmission efficiency which is an
`
`original feature ofeniMIMO communication.
`
`On the other
`
`hand,
`
`for data to be transmitted with higher priority,
`
`10
`
`15
`
`20
`
`25
`
`|PR2018—O1476
`
`Apple Inc. EX1002 Page 11
`
`IPR2018-01476
`Apple Inc. EX1002 Page 11
`
`

`

`12
`
`two transmission systems
`
`(at least two transmission
`
`systemswhentherearethreeormoretransmissionsystems)
`
`are always used and such data is spread/modulated using
`
`different spreading codes, and therefore it is possible
`
`to separate signals through despreading processing even
`
`when an interference compensation error increases due
`
`toinfluencesofanfixtureofnoise,etc.,onthereceiving
`
`side,
`
`that is, when sufficient separation performance
`
`using the MIMO technology cannot be obtained.
`
`Thus,
`
`this embodiment can improve the reception
`
`performancecnithe receiving side for specific¢data while
`
`maintaining the transmission efficiency of the
`
`communication system.
`
`When a turbo code is used as an error correcting
`
`code for the CDMA transmission apparatus according to
`
`this embodiment, systematic bits can also be used as the
`
`specific data. When turbo decoding is performed using
`
`systematicbitsandparitybits,thesystematicbitshave
`
`large influences on the error rate characteristic of the
`
`data after the turbo decoding. Therefore, using
`
`systematic bits as the specific data can improve the
`
`reception quality of the systematic bits and can improve
`
`the error rate characteristic of the data after the turbo
`
`decoding.
`
`Furthermore, when transmit power control
`
`is
`
`performed,
`
`transmit power may also be used instead of
`
`10
`
`15
`
`20
`
`25
`
`channel quality. This is because when transmit power
`
`controlisperformed,inthecaseofpoorchannelquality,
`
`
`
`|PR2018—O1476

`
`IPR2018-01476
`Apple Inc. EX1002 Page 12
`
`

`

`13
`
`the transmit power must also have increased according
`
`to the channel quality.
`
`Furthermore,aretransmissioncountofdatacanalso
`
`be used instead of the channel quality. This is because
`
`in the case of poor channel quality,
`
`the retransmission
`
`count of data must also have increased.
`
`The CDMA transmission apparatus according to the
`
`present invention is also applicable to a transmission
`
`apparatus using a multicarrier scheme such as an OFDM
`
`(Orthogonal Frequency Division Multiplex), and can
`
`thereby provide a multicarrier transmission apparatus
`
`having operations and effects similairto those described
`
`above.
`
`A transmission scheme using multicarriers has a
`
`symbol rate set to a low level
`
`(long symbol length) and
`
`has the effect of reducing interference among codes due
`
`to multipaths inaimultipath environment. Furthermore,
`
`byinsertingguardintervals,itjjsalsopossibleTXDremove
`
`interference among codes due to multipaths.
`
`Here,
`
`the case where the components of the present
`
`invention are incorporated in one CDMA transmission
`
`apparatushasbeenexplainedasanexample,butthepresent
`
`invention is also applicable to a case where spreading
`
`sections 102 to antenna 106—1, spreading sections 103
`
`to antenna 106*2, spreading control section 107, and
`
`control section 110 are incorporated in different
`
`apparatuses, constituting one communication system as
`
`a whole.
`
`Furthermore, an MIMO communication has been

`

`14
`
`explained as an example here, but the present invention
`
`is not
`
`limited to the MIMO communication and is also
`
`applicable to a case where different items of data are
`
`transmitted in parallel
`
`from a plurality of antennas
`
`(transmission systems).
`
`The CDMA transmission apparatus according to the
`
`present
`

`

`
`communication system,
`
`and can thereby provide a

`

`
`As described above,

`

`
`ABSTRACT
`
`A control section (110) recognizes the type of data
`
`included in a transmission signal and outputs a control
`
`signal
`
`(C1)
`
`to an 8/? conversion section (101)
`
`and a
`
`spreading control section (107).
`
`The 8/? conversion
`
`section (101) apportions a specific type of data output
`
`fron1the control section (110)1x3different transmission
`
`systems. Spreading sections (102, 103) carry out
`
`10
`
`15
`
`spreading processing on the specific type of data output
`
`from the 8/? conversion section (101) with different
`
`spreading codes assigned thereto under the control of
`
`thespreadingcontrolsection(107). Thedataoutputfrom
`
`thespreadingsections(102,103)istransmittedbylmdio
`
`through addition sections (104—1, 104~2),
`
`transmission
`
`sections (105—1, 105—2) and antennas (106-1, 106—2).
`
`In
`
`this way,
`
`it is possible to improve the reception
`
`performanceonthereceivingsideforspecificdatawhile
`
`maintaining the transmission efficiency of an MIMO
`
`20
`
`communication system.
