`

`(0003) A proposed communication system known as evolved UTRAN (E-UTRAN, also
`
`referred to as UTRAN-LTE, E-UTRA or 3.9G) is currently under development within the
`
`3GPP. The current working assumption is that the DL access technique will be OFDMA,and
`
`the UL access technique will be SC-FDMA.
`
`[0004] Onespecification of interest to these and otherissuesrelated to the invention is 3GPP
`
`TS 36.300, V8.4.0 (2008-03), 3rd Generation Partnership Project; Technical Specification
`
`Group Radio Access Network; Evolved Universal Terrestrial Radio Access (E-UTRA) and
`
`Evolved Universal Terrestrial Access Network (E-UTRAN); Overall description; Stage 2
`
`(Release 8), which is incorporated by reference herein in its entirety.
`
`(0005) Figure 1A reproduces Figure 4-1 of 3GPP TS 36.300, and showsthe overall
`
`architecture of the E-UTRAN system. The E-UTRAN system includes eNBs, providing the
`
`E-UTRA user plane (PDCP/RLC/MAC/PHY)and control plane (RRC) protocol terminations
`
`towards the UE. The eNBsareinterconnected with each other by means of an X2interface.
`
`The eNBsare also connected by means of an S1 interface to an EPC, morespecifically to a
`
`MME (Mobility Management Entity) by means of a S1-MME interface and to a Serving
`
`Gateway (S-GW) by meansof a S1-U interface. The S1 interface supports a many-to-many
`
`relation between MMEs/ Serving Gateways and eNBs.
`
`. Reference can also be made to 3GPP TS 36.321, V8.0.0 (2007-12), 3rd Generation
`[0006]
`Partnership Project; Technical Specification Group Radio Access Network; Evolved Universal
`Terrestrial Radio Access (E-UTRA) Medium Access Control (MAC) protocol specification
`
`(Release 8).
`
`[0007] Also of interest herein are the random access procedures of the LTE (E-UTRA)
`
`system. These procedures are described in 3GPP TS 36.300 v.8.4.0 at section 10.1.5
`
`(attached hereto as Exhibit A), shownat Figure 1B for the Contention Based Random Access
`
`Procedure and at Figure 1C for the Non-Contention Based Random Access Procedure.
`
`These respectively reproduce Figures 10.1.5.1-1 and 10.1.5.1-2 of 3GPP TS 36.300 v.8.4.0,
`
`and Exhibit A details the various steps shown.
`
`(0008] Briefly, the UE transmits a random access preamble and expects a responsefrom the
`eNB in the form of a so-called Message 2 (e.g., Random Access Responseat Figures 1B
`
`and 1C). Message 2 is transmitted on a DL shared channel DL-SCH (PDSCH, the PDCCH)
`
`and allocates resources on an UL-SCH (PUSCH). The resourceallocation of Message 2 is
`
`HTC/ZTE EXHIBIT 1014-5
`
`HTC/ZTE EXHIBIT 1014-5
`
`

`

`addressedwith an identity RA-RNTI that is associated with the frequency and time resources
`
`of a PRACH, but is common fordifferent preamble sequences. The Message 2 contains UL
`
`allocations for the transmissions of a Message 3 in the UL (e.g., step 3 of the Contention
`
`Based Random Access Procedure at Figure 1B).
`
`{0009] RACH preamblesare transmitted by the UEsusing a full path-loss compensation PC
`
`formula. The target is that reception RX level of those preambles at the eNB is the same,
`
`and so independentof path-loss. This is needed because several simultaneous preamble
`
`transmissions can take placein the same PRACH resourceand in order to detect them, their
`
`power at the eNB needsto be roughly the sameto avoid the well-known near-far problem for
`
`spread spectrum transmissions. However subsequentuplink transmissions on the PUSCH
`
`are orthogonal, and so called fractional power control can be used. This allows higher
`
`transmit TX powers for UEs that are near the eNB becauseinterference that those UEs
`
`generate to neighborcells is small as compared to cell edge UEs. This method allows higher
`
`average uplink bit rates on the PUSCH.
`
`(0010)
`
`In general, the eNB does not know whatis the path-loss value used bythe UE in its
`
`full PL compensation PC formula used for the UE’s RACH message.
`
`In the case of a UE
`
`being handed-overfrom another eNB, an estimate of the path-loss value could be provided to
`
`the target cell/eNB based on UE measurementreports sent to the serving eNB priorto the
`
`handover. However,for an initial access or for UL or DL data arrival this is not possible since
`
`there is no handover. Becauseofthis, the eNB doesnot know the powerdifference between
`the UE’s RACH preamble transmission and the UE’s transmission using the PUSCH power
`formula.
`
`[0011]
`
`It has been agreed that Message 2 contains a power contro! command for
`
`transmission of Message 3, but the definition and objective of that command is not yet
`
`specified. Therefore the eNB doesnot have sufficient information to give a correct power
`
`control command in response to the UE’s RACH message. The result then, and as
`
`mentioned above, is that the power that the UE usesfor transmission of Message3 is not
`
`knownto the eNB if the UE uses the PUSCH PC formula for sending Message3.
`
`[0012] The problem therefore may be stated as how best to define a transition from the full
`
`path loss compensated preamble transmission to the PUSCH (fractional) power control
`
`system.

`
`architecture of the E-UTRAN system.
`
`(0015) Figures 1B and 1C respectively reproduce Figures 10.1.5.1-1 and 10.1.5.1-2 of 3GPP
`
`TS 36.300 v8.4.0, Contention Based Random Access Procedure and Non- Contention Based

`Random Access Procedure.
`
`[0016] Figure 2 shows a simplified block diagram of various electronic devices that are
`
`suitable for use in practicing the exemplary embodiments of this invention.

`
`DETAILED DESCRIPTION:
`
`In the specific examples given below, the problem solved by those embodimentsis
`[0018]
`how the powercontrol formulas for PUSCH and PUCCH are takenin use during orafter the
`Random Access procedure.
`
`(0019] To the inventors’ knowledge this problem has not been solved before. Operation
`
`according to 3GPP TS 36.213 v.8.2.0 (attached hereto as Exhibit B) is that Message 3 (see
`
`Figure 1B) is transmitted using the PUSCH PCformula taking into account the PC command
`
`received from the eNB in Message2 (see Figures 1B and 1C). However, this does not specify
`
`how the VE specific parameters of the PUSCH and PUCCH power contro! formulas are
`initialized.
`
`[0020] The PUSCH PCformula for the UE in the ith subframe is defined at section 5.1.1.1 of
`
`3GPPTS 36.213 v8.2.0 as follows:
`
`Pouscn (2) = min {Fyax 1010819puscy (4) + Popuscn UU) + @: PL + Aqp(TF(i)) + f()} (dBm);
`

`
`

`

`where,
`
`Puax is the maximum allowed power that depends on the UE powerclass
`
`Mpyscu (2) is the size of the PUSCH resource assignment expressed in numberof
`
`resource blocks valid for subframe i.
`
`Popuscu(J/) is a parameter composed of the sum of a 8-bit cell specific nominal
`
`component Ponommar_puscu(/) Signalled from higherlayers for j=0 and 7 in the
`
`range of [-126,24] dBm with 1dB resolution and a 4-bit UE specific component
`Po_us_puscu(/) Configured by RRC for j=0 and 1 in the rangeof[-8, 7] dB with 1dB
`
`resolution. For PUSCH (re)transmissions corresponding to a configured
`
`scheduling grant then /=0 and for PUSCH (re)transmissions corresponding to a
`
`received PDCCH with DCI format 0 associated with a new packet transmission
`
`then /=7.

`
`[0022] The preamble PC formula for the UE’s transmission on the RACH is:
`
`Preamble = Paget +PL+ APmpup (dBm),
`
`[3]
`
`where
`
`¢
`
`e
`
`Page iS the broadcasted target power;
`
`PL is the path loss that UE estimates from DL; and
`
`¢ APampup 1S the power ramp-up applied for preamble retransmissions.
`
`[0023] As can be seen above at equation [1], the formula for Pyyscy (2) depends on the
`current PUSCH power control adjustmentstate which is termed /(@). For accumulation, this
`
`adjustment state depends on previous adjustments madein previous subframes, even for the
`
`case where /(Z) is set to an absolute value sinceit is set for the subframe (i — Kpuscy) -
`
`When the UE first sends data on the PUSCH, there is no previous subframe and so /=0,
`
`whichis addressed in 3GPP TS 36.213 v8.2.0 as zeroing out the entire term so that £(0)=0.
`
`Further, while it is true that the UE is to resetits accumulation whenever it receives a new
`
`UE-specific portion Pouzpuscn(/) Of the Popuscu(/) (and similarly for Pypuccy ), aftera RACH
`
`access the UE has received no UE-specific portion and soit lacks that parameter to reset
`
`according to 3GPP TS 36.213.
`
`(0024) Also, at equation [2] the powercontrol formula for the PUCCH P,y¢q;(@) depends on
`
`the current PUCCH powercontrol adjustment state which is termed g(i) and which also
`
`dependson previous adjustments madein previous PUCCH subframes. Whenthe UE first
`
`HTC/ZTE EXHIBIT1014-11
`
`HTC/ZTE EXHIBIT 1014-11
`
`

`

`sends a message on the PUCCH, there is no previous subframe and so/=0, whichis similarly
`
`addressed in 3GPP TS 36.213 v8.2.0 as zeroing out the entire term so that ¢(0) =0.
`
`(0025) Consider the case for contention-less random access, where the UE transmits
`
`preambles that are dedicated for that UE. This embodimentof the invention may also be
`
`used for contention based random access when it is considered that collisions will be
`
`infrequent enough so as not to substantially affect operation in the cell.
`
`[0026] According to this embodiment of the invention, the UE receives a powercontrol
`
`command (e.g., AP,, ) in the preamble responsefrom the eNB, which is Message 2. The UE
`
`then initiates the PC formula for PUSCH and PUCCH, or compensates open looperror,
`
`according to the following equations:
`
`©
`
`©
`
`Py ve_puscu + f(0) = APoc + AP
`rampup
`
`Pyue_puccn + 8(0) = APag + APampup
`
`[4a]
`
`[4b]
`
`[0027] These equations say that the sum of the UE specific power control constants
`
`(Pouepuscu OF Pouspuccu) and the powercontrolinitial states ( (0) or g(0)) is equal to the
`
`openloop powercontrolerror, taking into account the preamble power ramp-up. AP,. is here
`assumedto be the difference between the target preamble power and the power that eNB
`actually observes. The actual value of AP,~ May be signalled directly by the eNB as the
`power control command, or to save on signalling overhead the eNB mayexplicitly signal a bit
`
`sequence (one, two or morebits) as the power control commandwhichthe receiving UE uses
`
`to look up the true value AP,,.
`
`in a locally stored table.
`
`[0028] There are several options for dividing the correction between the UE specific
`
`constants and the powercontro! states. For example, in a first option the UE specific power
`
`control terms Pyyspuscy @Nd Pouepuccy Could beinitialized to zero and the whole correction
`
`is covered by f(0) or g(0). This can be always doneasfar as the power control state f is
`
`accumulated. (According to current 3GPP agreements g is always accumulating.) However,
`
`if f is modified with absolute PC commands, its dynamic rangeis limited and may not cover
`
`the whole open loop correction AP,. + APannp-
`
`If this happens,the part of the correction
`
`that cannot be included in (0) could be taken into account by adjusting Pouspuscu- AS

`HTC/ZTE EXHIBIT 1014-12
`
`

`

`another example, a second option is to take the open loop error into account adjusting
`
`principally the UE specific power control terms Poyspuscn @Nd Pouepuccn: These
`
`parameters have a limited range and the part of the open loop error that cannot be
`
`compensated by adjusting these UE specific constants could be covered byinitializing the
`
`power control states (0) or g(0) toa nonzero value. The benefit of the first option is that
`
`the eNB would knowthe UE specific constants Pougpuscn ANd Pouspuccu (atleast when f
`
`is accumulating), which might makelater adjustments of these constants easier. However,
`
`the second option could be more natural because the purposeof the UE specific constants is
`
`mainly to compensate systematic errors in the PL determination and TX powersetting and
`
`these are already visible as an error in the open loop powercontrol of the preambles. Of
`
`course, the above two options are presented only as non-limiting examples and this aspectof
`
`the invention is not limited to only those two.
`
`[0029] For the case of a dedicated preamble or when the preamblecollisions are otherwise
`
`infrequent, the power of Message 3 may be generated by using the PUSCH PC formula
`
`directly according to the above explained embodimentof the invention. This may lead to UE
`
`transmit TX power that is unnecessarily high, but the inventors do not see this as a problem.
`
`[0030] The inventors have determined that a problem could arise in the above explained
`
`procedure, specifically where two UEs transmit the same preamble sequence and use
`
`fractional PL compensation for Message 3. The problem appears most pronounced whenthe
`
`preamble of a UE with a large PL is received at the eNB stronger than the preamble of
`
`another UE with small PL. The fractional PC could result in Message 3 of the UE with the
`
`smaller PL being received at the eNB with a stronger signal strength than the Message3 of
`
`the UE with the larger PL. This would of course make detection by the eNB of the weaker
`
`Message3 lesslikely, despite the fact that in the above scenario the weaker Message3 is
`
`from the UE whohas received correct timing advance. Decoding of the stronger Message 3 is
`
`likely to fail because the timing advance of a wrong UE has been used whentransmitting it.
`
`Further,if the timing advance for Message 3 transmissions are set based on the preamble of
`
`the UE with the larger PL, then the UE with the smaller PL would use a large power and the
`
`wrong TA value when transmitting its Message 3, and thereby generate interferenceto other
`transmissions.
`
`[0031] To achieve improved performance when the UE performs contention based random
`
`access and when preamblecollisions are assumedto be frequent, another embodimentof
`
`the invention defines the Message 3 power relative to preamble power,i.e. full path loss
`
`10

`
`HTC/ZTE EXHIBIT 1014-13
`
`

`

`compensation used. The objective is that transmit TX power of Message 3 would not be
`
`unnecessary high.
`
`In one particular embodiment, this objective can be realized by using the
`
`following formula:
`
`Prrcgs = Psreamble + Ao,preamble _Msg3 + Apc _Msg3 + 10 10g 10Mpuscu (7)) + Arr (TF@)).
`
`[5]
`
`[0032] The terms Myysc, (2) and A;,(ZF(i)) in equation [5] are the same termsasin
`
`equation [1]. But the equation [5] term A
`
`0,preamble _
`
`Msgs correspondsto a typical poweroffset
`
`between a Message 3 and the preamble whose power corresponds to the detection
`
`threshold. The term A
`
`0,preamble_ Msg3
`
`can be a parameterbroadcast in System Information orit
`
`could be specified in the standard and pre-stored in the UE’s memory. The term Apeays IS
`
`the power control command included in the preamble response (e.g., Message 2), and as
`
`above the eNB maysignal it directly or more likely as a short bit sequence which the UE uses
`
`to access a lookup table for the true value.
`
`It
`
`is here named differently than the
`
`corresponding parameter A,,. of the first embodiment above because this power control
`
`command of the second embodimentis applicable only to Message 3 or to the PUSCH
`
`transmissions following Message 3 whereasthe parameter A,,. initializes the PC system for
`
`all the UL transmissions. After transmitting Message 3 or soon after that the UE should move
`
`to using Eq. [1] of the normal PUSCH powercontrol. For this purpose, the UE could report as
`
`early as possible, preferably already in Message 3, the poweroffset between the used power.
`
`and the power calculated with the PC Equation 1. With this knowledge, the eNB could then
`
`initialize the UE specific constants. The UE could also report other parameters that are
`
`unknown to eNB and provide same information e.g., power rampup value and pathloss or
`
`power rampup, power headroom and max UE power (UE powerclass). From a signalling
`
`point of view reporting the difference of the two formulas is most efficient. Alternative to
`
`reporting one or more parameters, the UE could, after transmitting Message 3, apply thefirst
`
`embodiment, equating Ape tO Ape ig; in Equations 4a and 4b
