Description

功率控制方法、网络设备和终端 The power control method, a network device and terminal

技术领域 FIELD

[0001] 本发明涉及无线通信技术领域,特别涉及一种功率控制方法、网络设备和终端。 [0001] The present invention relates to wireless communication technologies, and in particular relates to a power control method, a terminal and a network device.

背景技术 Background technique

[0002] 在传统的无线通信系统中,终端上行链路承载在一个单独的载波上,且终端使用的PA (Power Amplifier,功率放大器)也只有一个,因此,对终端进行功率控制只需在一个载波上进行。 [0002] In a conventional wireless communication system, the terminal uplink carried on a separate carrier, and a PA (Power Amplifier, PA) using only one terminal, thus the terminal in a power control only carried on a carrier. 一个终端有规定的最大上行发射功率,一个载波和一个PA也有各自允许的最大上行发射功率。 A terminal with a predetermined maximum uplink transmission power, a carrier and a PA has a respective maximum uplink transmission power allowed. 通常,基站会预先为终端配置一个上行发射功率,如果该上行发射功率没有超出终端的最大上行发射功率,则终端会使用该上行发射功率传输数据,如果该上行发射功率超出了终端的最大上行发射功率,则终端会采用该最大上行发射功率传输数据。 Typically, the base station preconfigured uplink transmit power of the terminal, if the uplink transmit power does not exceed the maximum uplink transmit power of the terminal, the terminal uses the uplink transmit power of the transmission data, if the uplink transmission power exceeds the maximum uplink terminal transmission power, then the terminal will use the maximum uplink transmission power to transmit data. 出于功率控制及调度的需要,终端需要通过PHR(Power Headroom Report,功率剩余空间报告)上报功率控制相关信息PH(Power Headroom,功率剩余空间)给基站,以方便基站了解终端的功率配置信息,精确获得当前终端所使用的上行发射功率,对终端的上行功率使用情况进行监控,进而进行功率调整或者调度决策。 Need for power control and scheduling, the terminal need PHR (Power Headroom Report, Report of power remaining space) reporting power control related information PH (Power Headroom, the power surplus space) to the base station, the base station in order to facilitate understanding of the configuration information of the terminal power, obtaining precise uplink transmit power currently used by the terminal, the terminal for uplink power monitor usage, and further adjusting the power or scheduling decisions.

[0003]在 LTE(Long-term Evolution,长期演进)系统中,PUCCH(Physical UplinkControll Channel,物理上行控制信道)和F1USCH(Physical Uplink Shared Channel,物理上行共享信道)不能同时发送,并且PUCCH没有PH,仅PUSCH存在PH。 [0003] In the LTE (Long-term Evolution, LTE) system, PUCCH (Physical UplinkControll Channel, physical uplink control channel) and F1USCH (Physical Uplink Shared Channel, physical uplink shared channel) can not simultaneously transmit and PUCCH is not PH, only the presence of PH PUSCH. PUSCH(PhysicalUplink Shared Channel,物理上行共享信道)的功率Ppusai以及PH的公式分别如下: PUSCH (PhysicalUplink Shared Channel, physical uplink shared channel) and the power Ppusai PH formula are as follows:

[0004] Ppusch (i) = min{PCMAX, IOlog10 (MPUSCH(i))+P0—PUSCH(j) + a (j).PL+Δ TF(i)+f (i)} [dB] [0004] Ppusch (i) = min {PCMAX, IOlog10 (MPUSCH (i)) + P0-PUSCH (j) + a (j) .PL + Δ TF (i) + f (i)} [dB]

[0005] PH(i) = Pcmax- (IOlog10 (Mpusch(i)) +Po pusch(j) + a (j).PL+Δ TF (i)+f (i)} [dB] [0005] PH (i) = Pcmax- (IOlog10 (Mpusch (i)) + Po pusch (j) + a (j) .PL + Δ TF (i) + f (i)} [dB]

[0006] 其中,Pcmx是终端的最大上行发射功率,由于LTE系统中仅有一个载波及一个PA,所以Pattx也是该载波允许的最大发射功率,同时也是该PA允许的最大发射功率,IOlog10(Mpusch⑴)+Po pusch(j) +a (j).PL+Atf⑴+f (i)是基站为该终端配置的上行发射功率,其取值可以大于Pqm ;i是指第i个子帧,j对应I3USCH传输的类型,包括半静态调度、动态调度和随机接入传输,j的取值范围为10,1,2},公式中的MPUSCH(i),Po pusch(J),a (j),ΔΤΡ(ΐ), f(i)等参数均由基站配置并下发给终端,Mpusch(I)是第i子帧在该载波上分配给该终端的物流资源块数量(单位为PRB,Physical Resource Block), Po pusch(J)是由网络侧配置的终端要达到的目标功率期望值,a (j)是路损补偿因子,用来控制对路损的全补偿或部分补偿,AtfQ)是与传输格式相关的参数,f(i)是由TPC下发的功率控制指令,而PL(PathLoss,下行路损)是由终端 [0006] wherein, pCMX is the maximum uplink transmit power of the terminal, since the LTE system, only one PA and a carrier, the carrier is so Pattx allowed maximum transmit power, but also the maximum allowable PA transmit power, IOlog10 (Mpusch⑴ ) + Po pusch (j) + a (j) .PL + Atf⑴ + f (i) is a base station for the uplink transmit power of the terminal configuration, which may be greater than the value PQM; i refers to the i-th frame, j corresponding to I3USCH type of transmission, including semi-persistent scheduling, scheduling, and dynamic random access transmission, j is the range 10,1,2}, equation MPUSCH (i), Po pusch (J), a (j), ΔΤΡ (ΐ), f (i) by the parameters at the base station to the terminal and configured, Mpusch (I) is the number of i-th stream of resource blocks allocated to the sub-frame of the terminal on the carrier (in units of PRB, Physical resource block ), Po pusch (J) is a terminal configured by the network side to achieve the target power value, a (j) is a path loss compensation factor, to control the loss of the whole LO or partially complement, AtfQ) is a transport format relevant parameters, f (i) is controlled by a TPC command issued by the power, and PL (pathLoss, downlink path loss) by the terminal 算出并保存在终端的。 Calculated and stored in the terminal.

[0007] PH的取值范围为[40,-23] dB,步长为ldB。 [0007] PH in the range [40, -23] dB, step size ldB. 当PH彡O时,表示终端的实际上行发 When the PH San O, actually represents the line terminal hair

射功率已达到最大值。 It has reached its maximum transmit power.

[0008] 由上述公式可知,PPUSCH(i)是在P.和基站配置给终端的上行发射功率中取最小值,即使基站配置给终端的上行发射功率大于Pqm,也始终存在如下关系=Ppusch (i) ( Pcmx^因此,LTE系统不需要功率回退。 [0008] From the above equation, PPUSCH (i) is arranged in the base station to the P. and uplink transmit power takes a minimum value in the terminal, even if the base station is configured to transmit uplink power is greater than the terminal PQM, there is always a relationship = Ppusch ( i) (pcmx ^ Therefore, LTE system does not require power backoff.

[0009] 在LTE-A系统中,增加了载波聚合的场景,即一个终端可以同时使用一个以上的载波与基站进行通信,而且取消了PUCCH和PUSCH不能同时发送的限制。 [0009] In the LTE-A system, increasing the carrier aggregation scenario, i.e., a terminal may use more than one carrier simultaneously communicate with a base station, and the removal of restrictions PUCCH and PUSCH can be transmitted simultaneously. 载波聚合存在两种场景,连续载波聚合和非连续载波聚合。 There are two scenarios of carrier aggregation, contiguous carrier aggregation and non-contiguous carrier aggregation. 连续载波聚合是指聚合的多个载波位于同一个波段,并且频率上是相邻的;非连续载波聚合是指聚合的多个载波频率上相隔较远,甚至位于不同的波段。 Carrier aggregation refers to the continuous polymerization of a plurality of carriers located in the same band and the upper frequency is adjacent; refers to non-contiguous carrier aggregation farther apart on a plurality of carrier frequencies polymerization, even located in different bands. 载波聚合的引入也给终端上行发射机的硬件结构带来变化,连续载波聚合的发射机可以使用单个或多个PA来实现,而非连续载波聚合必须使用多个PA来实现。 Carrier aggregation is introduced to the terminal also brings up a hardware configuration change of transmitter, transmitter contiguous carrier aggregation may be used to implement a single or multiple PA, rather than a continuous polymeric carrier must be implemented using a plurality of PA.

[0010] 对于LTE-A系统,由于网络侧仍只配置终端的最大发射功率,所以每个载波的最大发射功率都为终端的最大发射功率,从而会导致所有载波上的功率之和超过终端的最大上行发射功率的情况发生,进而造成终端无法实现上行发射或者上行发射功率过高导致对其他终端的干扰过大。 [0010] For the LTE-A system, since the network side still only set the maximum transmit power of the terminal, the maximum transmission power of each carrier are maximum transmit power of the terminal, which will result in the sum of the power of all the carriers exceeding terminals the maximum uplink transmit power occurs, which causes the terminal can not be achieved uplink transmission or uplink transmit power is too high cause interference to other terminals too large.

[0142] 本实施例中,单PA结构的终端可以如图6所示,该终端共有4个载波,4个载波上的信号通过一个PA传输。 [0142] In this embodiment, the terminal structure may be a single PA shown in FIG. 6, a total of four carriers of the terminal, four signal on a carrier through a transmission PA.

[0143] 本实施例中,如果基站在计算功率回退因子时,参考了载波的优先级,则终端的多个载波中,承载PUCCH信道的载波优先级高,承载PUCCH和PUSCH混合信道的载波优先级次之,承载PUSCH信道的载波优先级最低,从而保证优先回退承载PUSCH信道的载波的功率,以尽量保证PUCCH信道的传输。 [0143] In this embodiment, if the base station in the calculation of the power back-off factor, with reference to the priority carrier, a plurality of carriers of the terminals, the high carrier priority bearer PUCCH channel, the carrier carrier PUCCH and PUSCH mixing channel the second highest priority bearer channel PUSCH carrier lowest priority, thereby ensuring priority backoff power of the carrier carrying a PUSCH to try to ensure transmission of the PUCCH channel.

[0144] 2)终端的功率放大器为多个[0145] 此时,505可以具体包括: PA [0144] 2) a plurality of terminal [0145] In this case, 505 may specifically include:

[0146] 终端判断是否所有功率放大器均满足PAi小于或者等于PAimax,其中PAi为第i个功率放大器上所有载波的第二发射功率的总和,PAimax为第i个功率放大器的最大发射功率,i = 1,...,Y,Y为终端的PA的数量; [0146] the terminal determines whether all of the power amplifier can meet the maximum transmission power less than or equal PAi PAimax, wherein PAi is the sum of the second transmission power of all carriers on the i-th power amplifier, PAimax i-th power amplifier, i = 1, ..., Y, Y is the number of terminals PA;

[0147] 如果判断结果为否,则终端计算满足PAi > PAimax的第一功率放大器的第一调整值,第一调整值为第一功率放大器的最大发射功率与第一功率放大器上所有载波的第二发射功率的总和的差值,并将第一功率放大器的最大发射功率调整为第一放大器上所有载波的第二发射功率的总和; [0147] If the determination result is NO, the terminal calculates meet PAi> a first adjustment value of the first power amplifier PAimax, first of all carriers on a first adjustment value is the maximum transmit power of the first power amplifier with a first amplifier the sum of the difference between the sum of the two transmission power, and adjusting the maximum transmission power of the first power amplifier is first of all carriers on a second transmit power amplifier;

[0148] 终端下调满足PAi < PAimax的第二功率放大器的最大发射功率,第二功率放大器最大发射功率减少的总量等于第一功率放大器的第一调整值。 [0148] the terminal down to meet the maximum transmission power of the second power amplifier PAi <PAimax, the second power amplifier to reduce the maximum transmit power of the first adjustment value is equal to the total amount of the first power amplifier.

[0149] 本实施例中,满足PAi > PAimax的第一功率放大器可以为一个,也可以为多个,当为多个时,为每个第一功率放大器都计算出自己的第一调整值,从而得到多个调整值。 [0149] In this example embodiment, to meet PAi> PAimax first power amplifier may be one, or may be a plurality of, when a plurality of, for each first power amplifier have their calculated first adjustment value, whereby a plurality of adjustment values. 相应地,满足PAiCPAimax的第二功率放大器可以为一个,也可以为多个,如果有多个第二功率放大器,则在下调第二功率放大器的最大发射功率时,可以选取其中的全部或部分第二功率放大器来进行下调,只要保证进行下调的第二放大器的下调总量等于第一调整值即可,如果此时的第一调整值也为多个,则只要保证下调总量等于所有第一调整值之和即可,具体采用哪种方式实现,本发明实施例不做具体限定。 Accordingly, the second power amplifier is PAiCPAimax may be one, or may be a plurality, if a plurality of the second power amplifier is reduced when the maximum transmit power of the second power amplifier, can select all or a portion of which two power amplifier for the reduction, the total amount of the second amplifier is cut down for as long as the first adjustment value is equal to, if the first adjustment value in this case is also a plurality of, as long as the total amount of all of the first cut is equal to and to adjust the value, which way the specific implementation, the embodiments of the present invention is not specifically limited.

[0150] 本实施例中,计算第一调整值和将PA的最大上限调整为该PA上所有载波的第二发射功率的总和之间没有特定的执行顺序,当调整步骤在计算步骤之前执行时,计算步骤中使用的最大发射功率为调整前的最大发射功率。 [0150] In this embodiment, no particular order of execution between the sum of the calculated first adjustment value and the upper limit of the maximum adjustment PA PA for all carriers on a second transmission power, when the adjusting step is performed before the step of calculation , the maximum transmit power calculation step is used before the maximum transmit power adjustment.

[0151] 本实施例中,多PA结构的终端可以如图7所示,该终端共有4个载波,其中,载波I和2上的信号通过PAl传输,载波3和4上的信号通过PA2传输。 [0151] In this embodiment, the terminal may be a multi-PA structure shown in Figure 7, a total of four of the terminal carrier, wherein the carrier signal and I 2 PAl transmission, the carrier signal and transmitted over 4 3 PA2 . 以图7举例说明如下: In Figure 7 illustrates the following:

[0152]如果 PJWP4 ( Pcmax,判断是否PJP2 > PAlfflax* 且P3+P4 ( PA2fflax*,如果是,则将PAl的最大上行发射功率PAlma/修改为第一放大器的上行发射功率PJP2,并计算出差值offsetl = PfP2-PAlmax*,将PA2 的最大上行发射功率修改为PA2max* = PA2ma;-offsetl,即在原来的基础上减去该差值。终端通过将超限的PA的上限调高,将未超限的PA的上限调低,可以保证终端的功率不超限。相应地,终端在调整PA的上限后,为使终端和基站中的参数保持一致,终端还需要将改变后的参数上报给基站,基站收到后更新保存。 [0152] If PJWP4 (Pcmax, determines whether PJP2> PAlfflax * and P3 + P4 (PA2fflax *, if so, the maximum uplink transmission power PAl PAlma / modify uplink transmit power of the first amplifier PJP2, and calculates the difference value offsetl = PfP2-PAlmax *, the maximum uplink transmission power PA2 modify PA2max * = PA2ma; -offsetl, i.e., by subtracting the difference is based on the original PA limit overrun by the terminal to increase the. the upper limit of the PA down is not overrun, power of the terminal can be guaranteed not overrun. accordingly, after the adjustment of the terminal PA limit, for the parameters of the terminal and the base station are consistent, the terminal needs to report the changed parameter to the base station, the base station receives updated after save.

[0153] 本实施例中,当网络侧获取到每个载波的PHR后,如果终端功率超限,基站可以根据各个载波上承载的业务类型对资源分配进行调整,如适当降低NRTT (Not Real-TimeTraffic,非实时业务数据)的速率等。 [0153] In this embodiment, when the network side obtains the PHR for each carrier, if the power is out of the terminal, the base station may adjust allocation of resources according to the service type carried on respective carriers, such as due to lower NRTT (Not Real- TimeTraffic, non real-time traffic data) rate and so on.

[0154] 本实施例中,当终端发射机为单个PA时,PA最大发射功率PAmax等于终端最大上行发射功率Paffi ;当终端发射机为多个PA时,PA最大发射功率PAma/可以由网络侧计算得出并动态配置给终端。 [0154] In this embodiment, when the terminal transmitter is a single PA, PA is equal to the maximum transmit power of the terminal PAmax maximum uplink transmission power Paffi; when a plurality of terminal transmitter PA, PA maximum transmission power PAma / from the network side can be calculated and dynamic configuration to the terminal.

[0155] 需要说明的是:上述实施例4提供的方法中,终端在计算多个载波中每个载波的功率回退因子时,具体的计算方式与本实施例提供的网络侧设备在计算功率因子时用到的计算方式相同,不同的是,基站在计算功率因子时用到的PiS各个载波的实际上行发射功率的统计值,而终端在计算功率因子时用到的Pi为各个载波的实际上行发射功率。 [0155] It should be noted that: the method of Example 4 provided, in a terminal when the power calculating a plurality of carriers in the back-off factor for each carrier, the specific calculation method of the present embodiment provides a network-side apparatus in the embodiment calculates a power when used in the same manner as calculated factors, except that the base used in the calculation of the power factor PiS actual uplink transmission power of the statistical value of each carrier, and the terminal used when calculating the actual power factor Pi of each carrier uplink transmit power.

[0156] 本实施例提供的上述方法,基站在确定需要调整终端的功率时,根据载波信息计算出功率回退因子并发送给终端,使得终端能够根据该功率回退因子进行功率回退,实现了根据载波信息控制终端的功率回退,为LTE-A系统中多载波的应用场景下终端的功率回退提供了一个清楚的解决方案。 [0156] According to the method provided in the present embodiment, when the base station determines that an adjustment of the power of the terminal is calculated according to the carrier power back-off factor information sent to the terminal, enable the terminal to perform power back-off factor based on the power back-off, to achieve the information carrier according to the power control terminal backoff, provides a clear solution for the LTE-a system power in a multi-carrier scenario the terminal backoff. 另外,该方法还提供了如何动态地生成各个载波的功率回退因子,以及当终端功率超限时,单PA结构下/多PA结构下,控制信道和共享信道之间的功率如何分配的解决方案,可以更好的匹配信道及干扰状况,兼顾载波所承载的信道及业务类型的优先级,功率回退对系统的影响降至最低。 Additionally, the method also provides how to dynamically generate a power back-off factor of each carrier, and when the terminal power is out, the single structure of PA / PA multiple structure, and the power control channel between the allocation of the shared channel solution , you can better match the channel and interference conditions, the impact of the type of channel and business priorities, taking into account the power back carriers carried on the system to a minimum. 上述方法可以应用于任何多载波场景的功率控制中。 The above method may be applied to any multi-carrier power control of the scene.
