背景技术 Background technique

在 LTE ( Long Term Evolution, 长期演进） ***中，为了保证通信盾量，釆用主要手段之一是上行功率控制。通过上行功率控制可以尽可能减少相邻小区中使用相同资源发送数据的 UE ( User Equipment, 用户设备 )间千扰，并确保 UE的发射功率得到合理的使用。 In the LTE (Long Term Evolution) system, one of the main means of ensuring the communication shield is uplink power control. The uplink power control can minimize the interference between the UEs (User Equipments) that use the same resources in the neighboring cells, and ensure that the UE's transmit power is properly used.

需要控制的上行功率主要有 PUCCH ( Physical Uplink Control Channel, 物理上行控制信道）的发射功率、 PUSCH ( Physical Uplink Shared Channel, 物理上行共享信道）的发射功率、 SRS ( Souding Reference Signal, 探测用参考信号）的发射功率和 PRACH ( Physical Random Access Channel, 物理随机接入信道）信道的发射功率。 The uplink power to be controlled mainly includes the transmit power of the PUCCH (Physical Uplink Control Channel), the transmit power of the Physical Uplink Shared Channel (PUSCH), and the SRS (Souding Reference Signal).

Parameters - _PUCCH (F) is configured by the higher layer and corresponds to the power offset of the different PUCCH format relative to the PUCCH format la. Δτ^^') indicates the transmit diversity power offset. If the UE is configured to transmit on the 2 antenna port, the different PUCCH formats are configured by the higher layer signaling, and the value set is {0, -2} dB; Configured to transmit on a single antenna port, ^(^') =0. ^h ^ ⁿ CQi ^HARQ , n _SR ) is the power offset associated with the number of bits carried by puccH, where " ^c is the number of CSI (Channel State Information) bits of the bearer, " ^HARQ is the bearer ACK ( ACKnowledgment, positive acknowledgment) /NACK (Non-ACKnowledgment, negative acknowledgment) The number of bits, which is the number of SR (Scheduling Request) bits carried. ^P. - ^PUCCH is the PUCCH period g ('■) = g ('■ _ 1) + X ^PUCCH (' - k _m ) The power target value is configured by higher layer signaling. g(i) is the cumulative value of the power control command, where 4UCCH is the UE-specific correction value, also known as the TPC (Transmit Power Control) command. SpuCcCcHW-- represents the correction value obtained in the subframe i-k _m . For the TDD (Time Division Duplex) system, k _m is in the downlink subframe set that needs to perform uplink information feedback in the current subframe.

For the PUSCH power control adjustment amount, there are two ways of accumulating value and current absolute value.

在 LTE-A Rel-10中， UE在载波 c上传输 SRS所需要的发射功率 ^PSRS由以下公式定义：In LTE-A Rel-10, the transmit power ^P SRS required for a UE to transmit SRS on carrier c is defined by the following formula:

¾S,c (') = ^min { ^PCMAX, c (0, ¾S_OFFSET,c O) + 10 log₁₀( _SRS)C ) + P₀_PUSCH, c 0') + «_c(i)■ ^PLc + fc (') } [dBm] 其中， ^ps_RS__OTFSET，_c^)为载波 _c上不同天线端口配置下 _SRS相对于 puscH的功率偏移量， m=0对应周期 SRS , m=l对应非周期 SRS。 ^MsRS，^c是载波 c上的 SRS传输带宽，以 RB数表示。其余参数同该载波上的 PUSCH的功率控制参数。 3⁄4S,c (') = ^min { ^P CMAX, c (0, 3⁄4S_OFFSET,c O) + 10 log ₁₀ ( _SRS)C ) + P ₀ _PUSCH, c 0') + « _c (i) ■ ^PL c + fc (') } [dBm] Where ^p s _RS _ _OTFSET , _c ^) is the power offset of _SRS relative to puscH in different antenna port configurations on carrier _c , m=0 corresponds to period SRS, and m=l corresponds to aperiodic SRS. ^MsRS , ^c is the SRS transmission bandwidth on carrier c, expressed in RB number. The remaining parameters are the same as the power control parameters of the PUSCH on the carrier.

在 LTE-A Rel-10中， UE在主载波上传输 PRACH的发射功率由如下公式计算得到： PpRACH=min{ CMAX,c、 ) PREAMBLE RECEIVED TARGET POWER + In LTE-A Rel-10, the transmission power of the PRACH transmitted by the UE on the primary carrier is calculated by the following formula: PpRACH=min{ CMAX,c, ) PREAMBLE RECEIVED TARGET POWER +

^PLc }_[dBm] ^PL c }_[dBm]

其中， PREAMBLE_RECEIVED_TARGET_POWER 由 UE 的 MAC ( Media Access Control, 媒体接入控制）层计算得到，为 PRACH目标功率。 The PREAMBLE_RECEIVED_TARGET_POWER is calculated by the MAC (Media Access Control) layer of the UE and is the target power of the PRACH.

在 LTE-A Rel-10 中，上行功率控制方案是基于处在相同或者不同载波的 PUCCH和 PUSCH在一个子帧中同时传输的功率控制。如果 UE在当前子帧 i的总发射功率超过了 UE允许的最大发射功率，则在进行功率降低时， UE应优先保证 PUCCH的发射功率，等比例降低每个载波 c上的 PUSCH发射功率以满足 UE允许的最大发射功率的限制： In LTE-A Rel-10, the uplink power control scheme is based on power control in which PUCCH and PUSCH of the same or different carriers are simultaneously transmitted in one subframe. If the total transmit power of the UE in the current subframe i exceeds the maximum transmit power allowed by the UE, when performing power reduction, the UE should preferentially guarantee the transmit power of the PUCCH, and proportionally reduce the PUSCH transmit power on each carrier c to meet The maximum transmit power limit allowed by the UE:

其中 Ppu_SCH，_e ('')为 ¾jsc _e('')的线性域值， P_CMAX {i)为 UE允许的最大发射功率 P_eM4 ( ) 的线性域值， ^w('')为每个载波上的功率降低因子， ^Q≤w('')^≤1。如果当前子帧 i中没有 PUCCH 传输， ]IJ ^PPUCCH ('') =O。 Where Ppu _SCH , _e ('') is the linear domain value of 3⁄4jsc _e (''), P _CMAX {i) is the linear domain value of the maximum transmit power P _eM4 ( ) allowed by the UE, ^w ('') for each The power reduction factor on the carrier, ^Q ^≤ ^w ('') ^{≤ 1} . If there is no PUCCH transmission in the current subframe i, ]IJ ^P PUCCH ('') = O.

如果 UE在当前子帧 i中，同时存在承载 UCI ( Uplink Control Information, 上行控制信息）的 PUSCH传输以及没有承载 UCI的 PUSCH传输，且 UE的总发射功率超过了 UE 允许的最大发射功率，则 UE应优先保证 PUCCH的发射功率不降低，其次保证承载 UCI 的 PUSCH的发射功率不降低，并等比例降低每个载波上的 PUSCH发射功率以满足 UE允许的最大发射功率的限制：

If the UE is in the current subframe i, and there is a PUSCH transmission carrying UCI (Uplink Control Information) and a PUSCH transmission without carrying UCI, and the total transmit power of the UE exceeds the maximum transmit power allowed by the UE, the UE Priority should be given to ensure that the transmit power of the PUCCH is not reduced. Secondly, the transmit power of the PUSCH carrying the UCI is not reduced, and the PUSCH transmit power on each carrier is reduced proportionally to meet the maximum transmit power limit allowed by the UE:

当所有没有承载 UCI的 PUSCH功率都降低为 0时， UE的总发射功率还是超过 UE允许的最大发射功率，则进一步对承载 UCI 的 PUSCH降低功率。如果当前子帧 i 中没有 PUCCH传输，则 >UCCH ('') =O。 When all the PUSCH powers that do not carry the UCI are reduced to 0, the total transmit power of the UE still exceeds the maximum transmit power allowed by the UE, and the power is further reduced for the PUSCH carrying the UCI. If there is no PUCCH transmission in the current subframe i, then >UCCH ('') =O.

对于在同一个子帧中多个载波上同时传输的 SRS , 如果 UE的总发射功率超过了 UE 允许的最大发射功率，则对每个载波上的 SRS进行等比例功率降低以满足 UE允许的最大发射功率的限制：

其中 P_SR ( 为 ( 的线性域值，为每个载波 _c 上的 SRS 功率降低因子，For SRSs that are simultaneously transmitted on multiple carriers in the same subframe, if the total transmit power of the UE exceeds the maximum transmit power allowed by the UE, the SRS on each carrier is equally reduced to meet the maximum transmission allowed by the UE. Power limit:

Where P _SR is the linear domain value of (the SRS power reduction factor on each carrier _c ,

0 < w(i)≤ 1 0 < w(i)≤ 1

LTE-ARel-10定义的上行传输仅支持频带内（ Intra-band )的 CA ( Carrier Aggregation, 载波聚合），认为各个载波的无线信号传播特性近似，因此都基于 PCC ( Primary Component Carrier, 主成员载波）上的 PRACH过程获得的 TA ( Time Advance, 定时提前量）进行上行传输时间的调整，所以多个载波的上行发送时间对齐，因此功率控制可以以子帧为单位进行。 The uplink transmission defined by LTE-ARel-10 only supports Intra-band CA (Carrier Aggregation). It is considered that the radio signal propagation characteristics of each carrier are similar, so they are all based on PCC (Primary Component Carrier). The TA (Time Advance) obtained by the PRACH process on the uplink adjusts the uplink transmission time, so the uplink transmission times of the multiple carriers are aligned, so the power control can be performed in units of subframes.

在 LTE-ARel-11中，可以支持上行不同频带（ Inter-band )的 CA,以及 Macro e B( Macro Evolved Node B, 宏基站）和 RRH (远程无线头， Remote Radio Head ) 混合的 C A部署方案。由于不同频带的无线信号传播特性不同，并且宏基站和 RRH所经过的传播路径不同，会导致不同载波发送的信号到达基站的时间出现差异。因此， Rel-11 中，不同载波的 TA 可能不同，多个载波的上行发送时间不一定对齐，因此一个载波上的上行信道在一个子帧中的不同发送时间段内，可能与前一子帧的上行信道同时传输。因此，基于子帧的功率控制方案将不再适用。发明内容 In LTE-ARel-11, it can support CAs with different inter-band uplinks, and CA deployment schemes of Macro e B (Macro Evolved Node B) and RRH (Remote Radio Head). . Since the radio signal propagation characteristics of different frequency bands are different, and the propagation paths of the macro base station and the RRH are different, the time when the signals transmitted by different carriers arrive at the base station may be different. Therefore, in Rel-11, the TAs of different carriers may be different, and the uplink transmission times of multiple carriers are not necessarily aligned. Therefore, the uplink channel on one carrier may be in the different transmission period in one subframe, possibly with the previous subframe. The uplink channel is transmitted simultaneously. Therefore, the subframe-based power control scheme will no longer apply. Summary of the invention

当判断超过预设的最大发射功率时，对该上行信道 /信号集合中的上行信道 /信号的目标发射功率进行功率控制，以满足功率控制后，该上行信道 /信号集合中的各上行信道 /信号的发射功率之和不超过当前可用最大发射功率，当前可用最大发射功率为预设的最大发射功率减去上述相应的其他上行信道的发射功率。具体的功率控制方式有： When it is determined that the preset maximum transmit power is exceeded, power control is performed on the target transmit power of the uplink channel/signal in the uplink channel/signal set to satisfy each power control, and each uplink channel in the uplink channel/signal set/ The sum of the transmit powers of the signals does not exceed the currently available maximum transmit power, and the currently available maximum transmit power is the preset maximum transmit power minus the transmit power of the corresponding other uplink channels. The specific power control methods are:

或者，对该上行信道 /信号集合中的各上行信道 /信号按照信道 /信号优先级从低到高逐步进行功率降低，对具有相同信道 /信号优先级的多个信道 /信号的目标发射功率进行等比例功率降低，得到功率控制后各上行信道 /信号的发射功率，其中，对于不需要降低功率的上行信道 /信号，确定其目标发射功率为功率控制后的发射功率。具体的，对优先级最低的上行信道 /信号进行等比例功率降低，如果功率降低到 0 , 用户设备在该时刻的上行信道 / 信号的总功率仍然高于最大发射功率，则对优先级次低的上行信道 /信号进行等比例功率降低，以此类推，直至用户设备在该时刻的上行信道 /信号的总功率不高于最大发射功率。如果对某一个或者几个优先级较低的上行信道 /信号进行功率降低后就已经满足用户设备的上行信道 /信号的总功率不高于最大发射功率，则其它优先级的上行信道 /信号的发射功率保持不变，也就是说其目标发射功率即为功率控制后的发射功率。 Alternatively, the uplink channel/signal in the uplink channel/signal set is gradually reduced in power according to the channel/signal priority from low to high, and the target transmit power of multiple channels/signals having the same channel/signal priority is performed. The power of the uplink channel/signal after power control is obtained, and the uplink transmit channel/signal that does not need to be reduced in power is determined, and the target transmit power is determined as the transmit power after power control. Specifically, the equal-rate power is reduced for the lowest priority uplink channel/signal, and if the power is reduced to 0, the user equipment is at the uplink channel at the moment/ If the total power of the signal is still higher than the maximum transmit power, the proportional channel power of the lower priority channel/signal is reduced, and so on, until the total power of the uplink channel/signal of the user equipment at that moment is not higher than the maximum. Transmit power. If the total power of the uplink channel/signal of the user equipment is not higher than the maximum transmit power after power reduction of one or several lower priority uplink channels/signals, the uplink channel/signal of other priorities The transmit power remains unchanged, that is, its target transmit power is the transmit power after power control.

或者，对该上行信道 /信号集合中处于相同频带的上行信道 /信号的目标发射功率进行等比例功率降低，对该上行信道 /信号集合中处于不同频带的上行信道 /信号的目标发射功率根据所处频带对应的功率降比例低系数进行功率降低，得到功率控制后各上行信道 /信号的发射功率。其中，功率降比例低系数为用户设备与基站预先约定的，或者为高层信令或 PDCCH ( Pyhsical Downlink Control Channel , 物理下行控制信道）信令通知的，高层信令包括 RRC ( Radio Resource Control, 无线资源控制）信令、 MAC ( Medium Access Control, 媒体接入控制）信令。较优地，功率降低比例系数可以基于不同频带特性进行配置，例如频点位置、带宽、信道状态、配置的传输信息类型、业务等。较优地，不同频带的功率降低比例系数可以相同，也可以不同；当不同频带的功率降低比例系数相同时，可固定配置，不需要约定或通知。 Or performing equal power reduction on the target transmit power of the uplink channel/signal in the same frequency band in the uplink channel/signal set, and the target transmit power of the uplink channel/signal in different frequency bands in the uplink channel/signal set according to the The power reduction ratio corresponding to the frequency band is reduced by a power factor, and the transmission power of each uplink channel/signal after power control is obtained. The power reduction ratio low coefficient is pre-agreed by the user equipment and the base station, or is signaled by a high layer signaling or a PDCCH (Pyhsical Downlink Control Channel), and the high layer signaling includes RRC (Radio Resource Control, wireless). Resource control) Signaling, MAC (Medium Access Control) signaling. Preferably, the power reduction scaling factor can be configured based on different frequency band characteristics, such as frequency location, bandwidth, channel status, configured transmission information type, traffic, and the like. Preferably, the power reduction ratio coefficients of different frequency bands may be the same or different. When the power reduction ratio coefficients of different frequency bands are the same, the configuration may be fixed, and no agreement or notification is needed.

或者，按照信道 /信号优先级从低到高的顺序，逐步对该上行信道 /信号集合中具有同一信道 /信号优先级的处于相同频带的信道 /信号的目标发射功率进行等比例功率降低，对该上行信道 /信号集合中具有同一信道 /信号优先级的处于不同频带的信道 /信号的目标发射功率按照所处频带对应的功率降低比例系数进行功率降低，得到功率控制后各上行信道 / 信号的发射功率，其中，对于功率降低比例系数为 1的上行信道 /信号功率，确定其目标发射功率为功率控制后的发射功率，对于不需要降低功率的上行信道 /信号，确定其目标发射功率为功率控制后的发射功率。具体的，对优先级最低的上行信道 /信号进行功率降低，即对处于同一频带的信道 /信号进行等比例功率降低，处于不同频带的信道 /信号根据所处频带的功率降低比例系数进行功率降低，如果具有最低优先级的信道 /信号的功率降低到 0 , 用户设备在该时刻的上行信道 /信号的总功率仍然高于最大发射功率，则对优先级次低的上行信道 /信号进行功率降低，即即对处于同一频带的信道 /信号进行等比例功率降低，处于不同频带的信道 /信号根据所处频带的功率降低比例系数进行功率降低，以此类推，直至用户设备在该时刻的上行信道 /信号的总功率不高于最大发射功率。如果对某一个或者几个优先级较低的上行信道 /信号进行功率降低后就已经满足用户设备的上行信道 /信号的总功率不高于最大发射功率，则其它优先级的上行信道 /信号的发射功率保持不变，也就是说其目标发射功率即为功率控制后的发射功率。其中，信道 /信号优先级为： Or, according to the order of channel/signal priority from low to high, gradually reducing the target transmit power of the channel/signal in the same frequency band with the same channel/signal priority in the uplink channel/signal set, The target transmission power of the channel/signal in different frequency bands having the same channel/signal priority in the uplink channel/signal set is reduced according to the power reduction ratio coefficient corresponding to the frequency band, and the uplink channel/signal after power control is obtained. Transmit power, where, for the uplink channel/signal power with a power reduction proportional coefficient of 1, the target transmit power is determined as the transmit power after power control, and for the uplink channel/signal that does not need to reduce the power, the target transmit power is determined to be the power. Controlled transmit power. Specifically, power reduction is performed on the lowest priority uplink channel/signal, that is, the channel/signal in the same frequency band is reduced in equal power, and the channel/signal in different frequency bands is reduced in power according to the power reduction proportional coefficient of the frequency band in which the frequency band is located. If the power of the channel/signal with the lowest priority is reduced to 0, and the total power of the uplink channel/signal of the user equipment at this moment is still higher than the maximum transmit power, the power of the lower priority channel/signal is reduced. That is, the channel/signal in the same frequency band is reduced in equal power, and the channel/signal in different frequency bands is reduced in power according to the power reduction ratio coefficient of the frequency band, and so on, until the user equipment is in the uplink channel at the moment. The total power of the /signal is not higher than the maximum transmit power. If the total power of the uplink channel/signal of the user equipment is not higher than the maximum transmit power after power reduction of one or several lower priority uplink channels/signals, the uplink channel/signal of other priorities The transmit power remains unchanged, that is, its target transmit power is the transmit power after power control. Among them, the channel/signal priority is:

PUCCH>承载 UCI的 PUSCH>不承载 UCI的 PUSCH>SRS; PUCCH>PUSCH carrying UCI>PUSCH>SRS not carrying UCI;

或者， PUCCH>承载 UCI的 PUSCH>不承载 UCI的 PUSCH=SRS; Or, PUCCH>PUSCH carrying UCI>PUSCH=SRS not carrying UCI;

如果存在 PRACH, 则： If there is a PRACH, then:

或者， PRACH>PUCCH>承载 UCI的 PUSCH>不承载 UCI的 PUSCH>SRS; Or, PRACH>PUCCH>PUSCH carrying UCI>PUSCH>SRS not carrying UCI;

或者， PRACH>PUCCH>承载 UCI的 PUSCH>不承载 UCI的 PUSCH=SRS; Or, PRACH>PUCCH>PUSCH carrying UCI>PUSCH=SRS not carrying UCI;

或者， PUCCH>PRACH>承载 UCI的 PUSCH>不承载 UCI的 PUSCH>SRS; Or, PUCCH>PRACH>PUSCH carrying UCI>PUSCH>SRS not carrying UCI;

或者， PUCCH> PRACH>承载 UCI的 PUSCH>不承载 UCI的 PUSCH=SRS。 Or, PUCCH>PRACH>PUSCH carrying UCI>PUSCH=SRS not carrying UCI.

其中， SRS包括周期 SRS和非周期 SRS,非周期 SRS的优先级大于或者等于周期 SRS 的优先级。 The SRS includes a periodic SRS and an aperiodic SRS, and the priority of the aperiodic SRS is greater than or equal to the priority of the periodic SRS.

当判断未超过预设的最大发射功率时，确定该上行信道 /信号集合中的各上行信道 /信号的目标发射功率为功率控制后各上行信道 /信号的发射功率。 When it is determined that the preset maximum transmit power is not exceeded, the target transmit power of each uplink channel/signal in the uplink channel/signal set is determined as the transmit power of each uplink channel/signal after power control.

如果当前上行子帧中存在 PUCCH或 PRACH传输，则用户设备在按照上行发送时间提前量从大到小的顺序，对当前上行子帧中传输的上行信道 /信号的目标发射功率进行功率控制之前，对当前上行子帧中的 PUCCH或 PRACH的目标发射功率进行优先功率控制。 If there is a PUCCH or a PRACH transmission in the current uplink subframe, the user equipment performs power control on the target transmission power of the uplink channel/signal transmitted in the current uplink subframe in descending order of the uplink transmission timing advance. Priority power control is performed on the target transmit power of the PUCCH or PRACH in the current uplink subframe.

PUCCH携带 UCI信息， PRACH为一个上行载波获取上行同步的重要信道，本实施例中认为 PUCCH或 PRACH的重要程度最高，因此无论 PUCCH或 PRACH所在的上行载波对应的上行发送时间提前量是大还是小，均先对 PUCCH或 PRACH的目标发射功率进行功率控制，以首先确定其发射功率。具体方式主要有两种： The PUCCH carries the UCI information, and the PRACH is an important channel for obtaining the uplink synchronization for the uplink carrier. In this embodiment, the importance of the PUCCH or the PRACH is considered to be the highest. Therefore, whether the uplink transmission time advance corresponding to the uplink carrier where the PUCCH or the PRACH is located is large or small. The power of the target transmit power of the PUCCH or the PRACH is first controlled to determine its transmit power first. There are two main ways:

方式一，当 PUCCH或 PRACH的初始传输时刻上不存在前一个相邻子帧中的上行信道 /信号传输时，用户设备确定 PUCCH或 PRACH的目标发射功率为 PUCCH或 PRACH 功率控制后的发射功率。即 PUCCH或 PRACH的发射功率不需要降低；其中，对于在当前上行子帧中传输的 PRACH, 由于 PRACH传输无上行发送时间提前量，该 PRACH仅会与当前上行子帧或者当前上行子帧以及后一个相邻上行子帧中的上行信道 /信号在全部或者部分符号上同时传输，不会与前一个相邻上行子帧中的上行信道 /信号同时传输，即当前子帧中的 PRACH的初始传输时刻上总是不存在前一个相邻子帧中的上行信道 /信号传输。 In the first mode, when there is no uplink channel/signal transmission in the previous adjacent subframe at the initial transmission time of the PUCCH or the PRACH, the user equipment determines that the target transmission power of the PUCCH or the PRACH is the transmission power after the PUCCH or PRACH power control. That is, the transmit power of the PUCCH or the PRACH does not need to be reduced; wherein, for the PRACH transmitted in the current uplink subframe, since the PRACH transmission has no uplink transmission time advance, the PRACH is only related to the current uplink subframe or the current uplink subframe and thereafter. The uplink channel/signal in a neighboring uplink subframe is transmitted simultaneously on all or part of the symbol, and is not simultaneously transmitted with the uplink channel/signal in the previous adjacent uplink subframe, that is, the initial transmission of the PRACH in the current subframe. There is always no uplink channel/signal transmission in the previous adjacent subframe at all times.

方式二，当 PUCCH或 PRACH的初始传输时刻上存在前一个相邻子帧中的上行信道 / 信号传输时，用户设备判断 PUCCH或 PRACH的目标发射功率与前一个相邻子帧中的上行信道 /信号的发射功率之和是否超过预设的最大发射功率。级逐步对上述相应的前一个相邻子帧中的上行信道 /信号的发射功率进行降低，以满足功率降低后，该时刻上 PUCCH或 PRACH的发射功率与上述相应的前一个相邻子帧中的上行信道 /信号的发射功率之和不超过预设的最大发射功率。例如，对于当前子帧中存在 PUCCH 传输时，在该 PUCCH的初始传输时刻上存在传输的前一个相邻子帧中的上行信道 /信号不包括 PRACH信道的情况中，即相应的前一个相邻子帧中的上行信道 /信号仅包括承载 UCI 的 PUSCH、不承载 UCI的 PUSCH以及 SRS中的一种或多种，此时，保持当前子帧中的 PUCCH的发射功率不变，按照信道 /信号优先级逐步上述对前一个相邻子帧中的上行信道 / 信号的发射功率进行降低。其中，对前一个相邻子帧中的上行信道 /信号的发射功率进行降低时，当具有最低优先级的信道 /信号发射功率与其他优先级的信道 /信号的发射功率之和超过最大发射功率时，可以直接将最低优先级信道 /信号的发射功率降低为 0 , 进一步对次低信道 /信号优先级的信道 /信号重复上述过程，直到 PUCCH或 PRACH的发射功率与前一个子帧中的上行信道 /信号的发射功率之和不超过最大发射功率；或者，对前一个子帧中的上行信道 /信号等比例降低功率；或者，对前一个子帧中的上行信道 /信号中处于同一频带的信道 /信号等比例降低功率，处于不同频带的信道 /信号按照频带对应的功率降低比例系数进行功率降低；或者，按照信道 /信号优先级，对具有同一信道 /信号优先级的多个信道 / 信号中处于同一频带的信道 /信号等比例降低功率，对具有同一信道 /信号优先级的多个信道 /信号中处于不同频带的信道 /信号按照频带对应的功率降低比例系数进行功率降低。其中，上述功率降低过程中，可仅对前一个上行子帧中的上行信道 /信号中与 PUCCH 或 PRACH同时传输的 SC-FDMA ( Single Carrier-Frequency Division Multiple Access, 单载波频分多址接入）符号的发射功率进行降低。 Manner 2: When there is an uplink channel/signal transmission in a previous adjacent subframe at the initial transmission time of the PUCCH or the PRACH, the user equipment determines the target transmission power of the PUCCH or the PRACH and the uplink channel in the previous adjacent subframe/ Whether the sum of the transmit powers of the signals exceeds a preset maximum transmit power. The stage gradually reduces the transmit power of the uplink channel/signal in the corresponding previous adjacent subframe to meet the power reduction, and the transmit power of the PUCCH or PRACH at the moment is in the corresponding previous adjacent subframe. The sum of the transmit powers of the uplink channels/signals does not exceed the preset maximum transmit power. For example, when there is a PUCCH transmission in the current subframe, in the case where the uplink channel/signal in the previous adjacent subframe of the transmission does not include the PRACH channel at the initial transmission timing of the PUCCH, that is, the corresponding previous neighbor The uplink channel/signal in the subframe includes only one or more of the PUSCH carrying the UCI, the PUSCH not carrying the UCI, and the SRS. At this time, the transmission power of the PUCCH in the current subframe is kept unchanged, according to the channel/signal. The priority is gradually reduced as described above for the transmission power of the uplink channel/signal in the previous adjacent subframe. Wherein, when the transmit power of the uplink channel/signal in the previous adjacent subframe is decreased, when the sum of the channel/signal transmit power having the lowest priority and the transmit power of the channel/signal of other priorities exceeds the maximum transmit power When the transmission power of the lowest priority channel/signal can be directly reduced to 0, the above process is further repeated for the channel/signal of the second lowest channel/signal priority until the transmit power of the PUCCH or PRACH and the uplink in the previous subframe. The sum of the transmission power of the channel/signal does not exceed the maximum transmit power; or, the power is reduced in proportion to the uplink channel/signal in the previous subframe; or, in the same frequency band, the uplink channel/signal in the previous subframe The channel/signal ratio reduces power, and the channel/signal in different frequency bands performs power reduction according to the power reduction proportional coefficient corresponding to the frequency band; or, according to the channel/signal priority, multiple channels/signals having the same channel/signal priority level Channels/signals in the same frequency band are proportionally reduced in power, and have the same channel/signal priority The channels/signals in different frequency bands of the plurality of channels/signals of the stage are reduced in power according to the power reduction proportional coefficient corresponding to the frequency band. In the power reduction process, only SC-FDMA (Single Carrier-Frequency Division Multiple Access) that is simultaneously transmitted with the PUCCH or the PRACH in the uplink channel/signal in the previous uplink subframe may be used. The transmission power of the symbol is reduced.

或者，如果判断超过，按照信道 /信号优先级逐步对上述 PUCCH或 PRACH以及上述前一个相邻子帧中的上行信道 /信号的发射功率进行降低，以满足功率降低后，该时刻上 PUCCH或 PRACH的发射功率与前一个相邻子帧中的上行信道 /信号的发射功率之和不超过所述预设的最大发射功率。 Or, if the judgment is exceeded, the transmission power of the uplink channel/signal in the PUCCH or the PRACH and the previous adjacent subframe is gradually reduced according to the channel/signal priority to satisfy the power reduction, and the PUCCH or the PRACH is obtained at the moment. The sum of the transmit power and the transmit power of the uplink channel/signal in the previous adjacent subframe does not exceed the preset maximum transmit power.

即，当上述相应的前一个相邻子帧中的上行信道 /信号中包含信道 /信号优先级高于当前子帧中的 PUCCH或 PRACH的信道 /信号时，保持优先级高于该 PUCCH或 PRACH的信道 /信号的发射功率不变，将该 PUCCH或 PRACH的目标发射功率、预设的最大发射功率与优先级高于该 PUCCH 或 PRACH 的信道 /信号的发射功率之差的最小值，作为该 PUCCH或 PRACH功率控制后的发射功率，并按照信道 /信号优先级逐步对上述前一个相邻子帧中除了信道 /信号优先级高于当前子帧中的 PUCCH或 PRACH的信道 /信号以外的上行信道 /信号的发射功率进行降低，以满足功率降低后 , 该时刻上 PUCCH或 PRACH的发射功率与上述相应的前一个相邻子帧中的上行信道 /信号的发射功率之和不超过预设的最大发射功率。 That is, when the uplink channel/signal in the corresponding previous neighboring subframe includes a channel/signal with a channel/signal priority higher than the PUCCH or PRACH in the current subframe, the priority is higher than the PUCCH or PRACH. The transmission power of the channel/signal is unchanged, and the minimum of the difference between the target transmit power of the PUCCH or PRACH, the preset maximum transmit power, and the transmit power of the channel/signal having a higher priority than the PUCCH or PRACH is used as the The transmit power of the PUCCH or PRACH power control, and the uplink of the previous adjacent subframe except the channel/signal priority of the PUCCH or the PRACH in the current subframe is gradually stepped according to the channel/signal priority. The transmission power of the channel/signal is reduced to meet the power reduction, and the PUCCH or PRACH is sent at that moment. The sum of the transmit power and the transmit power of the uplink channel/signal in the corresponding previous adjacent subframe does not exceed the preset maximum transmit power.

其中，如果 PRACH的优先级高于 PUCCH, 则：保持前一个相邻子帧中的 PRACH的发射功率不变，按照信道 /信号优先级逐步对当前子帧中的 PUCCH以及相应的前一个相邻子帧中除了 PRACH的上行信道 /信号的发射功率进行降低，即，如果当前子帧中 PUCCH 的目标发射功率小于预设的最大发射功率与前一个相邻子帧中的 PRACH 的发射功率之差，则进一步保持当前子帧中的 PUCCH的发射功率不变，按照信道 /信号优先级，对相应的前一个子帧中的除了 PRACH以外的其他上行信道 /信号的发射功率进行降低，如果当前子帧中 PUCCH的目标发射功率超过预设的最大发射功率与前一个相邻子帧中的 PRACH 的发射功率之差，则将预设的最大发射功率与前一个相邻子帧中的 PRACH的发射功率之差作为当前子帧中的 PUCCH 功率控制后的发射功率，并将相应的前一个子帧中的除了 PRACH 以外的其他上行信道 /信号的发射功率降低为 0 , 即不发送这些信道 /信号；如果 PUCCH的优先级高于 PRACH, 则：保持当前子帧中的 PUCCH的发射功率不变，按照信道 /信号优先级逐步对相应的前一个相邻子帧中的上行信道 /信号的发射功率进行降低，具体步骤类似上述过程，即上述步骤中将当前子帧中的 PUCCH 与前一个相邻子帧中的 PRACH交换位置。 If the priority of the PRACH is higher than the PUCCH, the transmission power of the PRACH in the previous neighboring subframe is kept unchanged, and the PUCCH in the current subframe and the corresponding previous neighbor are gradually stepped according to the channel/signal priority. The transmit power of the uplink channel/signal except the PRACH in the subframe is reduced, that is, if the target transmit power of the PUCCH in the current subframe is smaller than the difference between the preset maximum transmit power and the transmit power of the PRACH in the previous adjacent subframe. And further maintaining the transmit power of the PUCCH in the current subframe unchanged, and reducing the transmit power of the uplink channel/signal other than the PRACH in the corresponding previous subframe according to the channel/signal priority, if the current sub-sub If the target transmit power of the PUCCH in the frame exceeds the difference between the preset maximum transmit power and the transmit power of the PRACH in the previous adjacent subframe, the preset maximum transmit power is transmitted with the PRACH in the previous adjacent subframe. The difference in power is used as the transmit power of the PUCCH power control in the current subframe, and the PRACH in the corresponding previous subframe The transmit power of other uplink channels/signals is reduced to 0, that is, the channels/signals are not transmitted; if the priority of the PUCCH is higher than the PRACH, then: the transmit power of the PUCCH in the current subframe is kept unchanged, according to the channel/signal The priority is gradually reduced to the transmit power of the uplink channel/signal in the corresponding previous adjacent subframe, and the specific procedure is similar to the foregoing process, that is, the PUCCH in the current subframe and the previous adjacent subframe are in the foregoing step. PRACH exchange location.

或者，如果判断超过，则将预设的最大发射功率与前一个相邻子帧中的上行信道 /信号的发射功率之差作为 PUCCH或 PRACH功率控制后的发射功率。例如，当当前子帧中存在 PUCCH传输时，在该 PUCCH的初始传输时刻上存在传输的前一个相邻子帧中的上行信道 /信号仅包括 PRACH、且功率控制时 PRACH的优先级高于 PUCCH的情况中，此时，保持前一个相邻子帧中的 PRACH的发射功率不变，将预设的最大发射功率与前一个相邻子帧中的 PRACH的发射功率之差作为当前子帧中 PUCCH的发射功率。 Or, if the judgment is exceeded, the difference between the preset maximum transmit power and the transmit power of the uplink channel/signal in the previous adjacent subframe is used as the transmit power after the PUCCH or PRACH power control. For example, when there is a PUCCH transmission in the current subframe, the uplink channel/signal in the previous adjacent subframe of the transmission at the initial transmission moment of the PUCCH includes only the PRACH, and the priority of the PRACH is higher than the PUCCH when the power is controlled. In this case, at this time, the transmit power of the PRACH in the previous adjacent subframe is kept unchanged, and the difference between the preset maximum transmit power and the transmit power of the PRACH in the previous adjacent subframe is taken as the current subframe. The transmit power of the PUCCH.

如果判断不超过，则确定 PUCCH或 PRACH的目标发射功率为 PUCCH或 PRACH功率控制后的发射功率。 If the judgment is not exceeded, it is determined that the target transmission power of the PUCCH or PRACH is the transmission power after the PUCCH or PRACH power control.

如果当前上行子帧中同时存在 PUCCH和 PRACH传输，用户设备在按照上行发送时间提前量从大到小的顺序，对当前上行子帧中传输的上行信道 /信号的目标发射功率进行功率控制之前，仅对 PUCCH和 PRACH中具有较高信道 /信号优先级的信道的目标发射功率进行优先功率控制。其中，具体的功率控制步骤按照上述方式一或者方式二进行，具体不再赘述。较优地，对上述 PUCCH和 PRACH中优先级较低的信道，可不做特殊处理，即按照上行发送时间提前量从大到小的顺序进行功率控制，或者，基于预设的最大发射功率与优先级较高的信道进行优先功率控制后的发射功率之差，将该差值作为当前的预设的最大发射功率，按照上述方式一或者方式二对优先级较低的信道进行优先功率控制。较优地，基站可以优先在 PCC上发送 PUCCH以尽可能保证 PUCCH的发射功率；或者，基站可以将具有最大 TA的上行载波作为 PCC , 以尽可能保证 PUCCH的发射功率。 If the PUCCH and the PRACH transmission exist in the current uplink subframe, the user equipment performs power control on the target transmit power of the uplink channel/signal transmitted in the current uplink subframe in descending order of the uplink transmission timing advance. Priority power control is only performed on the target transmit power of the channel having higher channel/signal priority in PUCCH and PRACH. The specific power control step is performed according to the foregoing mode 1 or mode 2, and details are not described herein. Preferably, the channel with the lower priority in the PUCCH and the PRACH may be not specially processed, that is, the power control is performed in descending order of the uplink transmission time advance, or based on the preset maximum transmit power and priority. The difference between the transmit power after the priority power control is performed on the higher-order channel, and the difference is taken as the current preset For the large transmit power, priority power control is performed on the lower priority channel according to the above manner 1 or 2. Preferably, the base station can preferentially transmit the PUCCH on the PCC to ensure the transmit power of the PUCCH as much as possible. Alternatively, the base station can use the uplink carrier with the largest TA as the PCC to ensure the transmit power of the PUCCH as much as possible.

较优地，上述方法中的上行信道 /信号包括但不限于： PUCCH、 PUSCH (承载 UCI的 PUSCH、未承载 UCI的 PUSCH )、 PRACH、 SRS等。 Preferably, the uplink channel/signal in the foregoing method includes but is not limited to: PUCCH, PUSCH (PUSCH carrying UCI, PUSCH not carrying UCI), PRACH, SRS, and the like.

较优地，对于在多个上行子帧连续发送的 PRACH, 其后续发送子帧中的发射功率可以以第一个发送子帧的发射功率为准，后续子帧中的上行信道的功率控制以 PRACH发送功率为基准进行 (即 PRACH发射功率固定不变）。即当 PRACH优先级最高时，可以将该连续传输的 PRACH的发射功率合并到每个传输子帧的预设的最大发射功率中，例如将每个子帧的原始预设的最大发射功率与该 PRACH的发射功率之差作为该子帧中进行功率控制时使用的预设的最大发射功率，进而基于该预设的最大发射功率对相应的上行信道 /信号进行功率控制。 Preferably, for the PRACH continuously transmitted in multiple uplink subframes, the transmit power in the subsequent transmit subframe may be based on the transmit power of the first transmit subframe, and the power control of the uplink channel in the subsequent subframe is The PRACH transmission power is based on the reference (ie, the PRACH transmission power is fixed). That is, when the PRACH priority is the highest, the transmit power of the continuously transmitted PRACH may be merged into the preset maximum transmit power of each transmission subframe, for example, the original preset maximum transmit power of each subframe and the PRACH. The difference between the transmit powers is used as the preset maximum transmit power used for power control in the subframe, and then the corresponding uplink channel/signal is power-controlled based on the preset maximum transmit power.

较优地，上述方法同时适用于 intra-band (频带内）和 inter-band (跨频带） CA (载波聚合）的场景。 Preferably, the above method is applicable to both intra-band (in-band) and inter-band (cross-band) CA (carrier aggregation) scenarios.

较优地，上述方法同时适用于 FDD和 TDD模式。 Preferably, the above method is applicable to both FDD and TDD modes.

下面通过两个典型实施例来详细介绍实现过程。 The implementation process is described in detail below through two exemplary embodiments.

参见图 2 , 本实施例中按照 TA从大到小顺序进行功率控制的方法流程如下：步骤 201 : 用户设备确定当前上行子帧中各载波上的每个上行信道 /信号的目标发射功率。 Referring to FIG. 2, the method for performing power control according to TA from large to small in this embodiment is as follows: Step 201: The user equipment determines a target transmit power of each uplink channel/signal on each carrier in the current uplink subframe.

步骤 202: 用户设备判断当前子帧中未进行功率控制的具有最大 TA的载波上的上行信道 /信号集合与在上行信道 /信号集合的初始发送时刻上同时传输的当前子帧中的上行信道 /信号，以及在上行信道 /信号集合的初始发送时刻上同时传输的前一相邻子帧中的上行信道 /信号的发射功率之和是否超过预设的最大发射功率，若是，则继续步骤 203 , 否则继续步骤 204。 Step 202: The user equipment determines the uplink channel/signal set on the carrier with the largest TA that is not subjected to power control in the current subframe, and the uplink channel in the current subframe that is simultaneously transmitted at the initial transmission time of the uplink channel/signal set/ And whether the sum of the transmit powers of the uplink channels/signals in the previous adjacent subframe simultaneously transmitted at the initial transmission time of the uplink channel/signal set exceeds a preset maximum transmit power, and if yes, proceeding to step 203, Otherwise proceed to step 204.

步骤 203 :用户设备对当前具有最大 TA的载波上的上行信道 /信号集合进行功率控制，使其与在上行信道 /信号集合的初始发送时刻上同时传输的当前子帧中的上行信道 /信号，以及在上行信道 /信号集合的初始发送时刻上同时传输的前一子帧上行信道 /信号的发射功率之和不超过预设的最大发射功率。 Step 203: The user equipment performs power control on the uplink channel/signal set on the carrier that currently has the largest TA, and makes the uplink channel/signal in the current subframe simultaneously transmitted at the initial transmission time of the uplink channel/signal set. And the sum of the transmit powers of the uplink channels/signals of the previous subframe simultaneously transmitted at the initial transmission time of the uplink channel/signal set does not exceed the preset maximum transmit power.

步骤 204: 用户设备将当前具有最大 TA的载波上的上行信道 /信号集合中各上行信道 / 信号的目标发射功率作为实际发射功率。 Step 204: The user equipment uses the target transmit power of each uplink channel/signal in the uplink channel/signal set on the carrier currently having the largest TA as the actual transmit power.

步骤 205 : 按照 TA从大到小顺序，用户设备继续对当前子帧中的未进行功率控制的上行信道 /信号重复上述步骤 202进行功率控制，直至满足当前子帧内任意时刻用户设备的总发射功率均不超过预设的最大发射功率。 Step 205: The user equipment continues to perform power control in the current subframe according to the order of the TAs from large to small. The uplink channel/signal repeats the above step 202 for power control until the total transmit power of the user equipment does not exceed the preset maximum transmit power at any time in the current subframe.

例如，参见图 3所示的传输示意图。用户设备聚合了 5个载波进行上行传输，由于 TA 不同，载波 1和 2的上行发送时间较载波 3、 4和 5提前 1个 SC-FDMA符号，传输情况如图 3所示，用户设备确定子帧 i ( i表示某个子帧）中信道的发射功率的具体行为如下：用户设备首先根据背景介绍部分的相关公式分别计算得到载波 1上 PUCCH的发射功率 P_{PUCC 1} )、载波 2上承载 UCI的 PUSCH的发射功率 ^PpuscH'²(^Z)、载波 3上未承载 UCI 的 PUSCH的发射功率 ^PpuscH'³(^Z)、载波 4上未承载 UCI的 PUSCH的发射功率 ^PpuscH'⁴(^Z)、载波 5上未承载 UCI的 PUSCH的发射功率 ^PpuscH,^{5 (Z}) ,并根据 ^{= 10¾/1}°确定其线性域值， ^Ρχ表示某一信道的发射功率。 See, for example, the transmission diagram shown in Figure 3. The user equipment aggregates 5 carriers for uplink transmission. The uplink transmission time of carriers 1 and 2 is 1 SC-FDMA symbol ahead of carriers 3, 4, and 5 due to different TAs. The transmission situation is shown in Figure 3. User equipment determinator The specific behavior of the transmission power of the channel in the frame i (i indicates a certain subframe) is as follows: The user equipment first calculates the transmission power P _{PUCC 1} of the PUCCH on the carrier 1 according to the correlation formula of the background introduction part, and carries the UCI on the carrier 2 The transmit power ^PpuscH ' ² ( ^Z ) of the PUSCH, the transmit power ^PpuscH ' ³ ( ^Z ) of the PUSCH that does not carry the UCI on the carrier 3, and the transmit power ^PpuscH ' ⁴ ( ^Z ) of the PUSCH that does not carry the UCI on the carrier 4, on the carrier 5 The transmission power ^PpuscH , ^{5 (Z} ) of the PUSCH that does not carry UCI, and its linear domain value is determined according to ^{= 103⁄4/1} °, and ^Ρχ represents the transmission power of a certain channel.

按照 ΤΑ从大到小的顺序，首先确定对具有最大 ΤΑ的载波 1和 2上的上行信道 /信号集合进行功率控制：功率控制需要当前时刻上与当前上行信道 /信号集合中的上行信道 /信号同时传输的其他上行信道 /信号的发射功率，其他上行信道包括当前上行子帧中至少与上行信道 /信号集合中的上行信道 /信号的部分符号同时传输的已经经过功率控制的上行信道 / 信号，和 /或当前上行子帧的前一个相邻子帧中在初始发送时刻上存在传输的上行信道 /信号，此处其他上行信道主要指当前上行子帧的前一个相邻子帧中在当前上行信道 /信号集合的初始发送时刻上存在传输的上行信道 /信号，由于载波 1和 2上的 PUCCH和 PUSCH初始发送时刻上，在子帧 i-1中载波 3上存在 PUSCH传输，且该 PUSCH的发射功率已经确定为 ^{Ppusc 3}(^{Z _ 1}) , 则此处的其他上行信道 /信号即为子帧 i-1中载波 3上 PUSCH, 则用户设备判断在该发送时刻上，载波 1上的 PUCCH、载波 2上的 PUSCH以及载波 3子帧 i-1 中的 PUSCH的发射功之和是否超过用设备允许的最大发射功率 ΜΑΧ。当判断 ^^» +

There is a transmitted uplink channel/signal at the initial transmission time of the channel/signal set. Due to the PUCCH and PUSCH initial transmission time on carriers 1 and 2, there is PUSCH transmission on carrier 3 in subframe i-1, and the PUSCH is transmit power has been determined as ^{Ppusc 3} ^{(Z _ 1),} the other uplink channels / signal here is the subframe i-1 in the carrier 3 PUSCH, the The user equipment determines the transmission timing, PUCCH on the carrier 1, PUSCH on carrier 2 and carrier 3 ΜΑΧ subframe maximum transmission power and the transmission power of the equipment exceeds the allowable i-1 in the PUSCH. When judging ^^» +

_ ^{: >} ^3⁄4^ ;), the power control needs to be performed on the PUCCH on carrier 1 and the PUSCH on carrier 2, as follows:

釆用方法 1 : 根据公式（1 ),对上述上行信道集合中的所有信道 /信号等比例降低功率，其中 c为载波编号，为在上行信道 /信号集合的初始发送时刻上，当前上行子帧中至少与上行信道 /信号集合中的上行信道 /信号的部分符号同时传输的已经经过功率控制的上

Method 1: According to formula (1), the power is reduced in proportion to all channels/signals in the uplink channel set, where c is the carrier number, which is the current uplink subframe at the initial transmission time of the uplink channel/signal set. At least simultaneously with the partial transmission of the upstream channel/signal in the upstream channel/signal set that has been power controlled

( 1 ) 由于本例中没有 SRS传输，则 c ' 等于 o。公式中 _c为载波编号， i为子帧编号。釆用方法 2: 按照信道 /信号优先级，对具有最低优先级的多个信道 /信号进行等比例功率降低，即：首先根据公式（2 )对 SRS (如果存在 SRS )等比例降低功率，如果存在非 0 的 w(i), 则功率降低结束，保持 PUCCH、 PUSCH和 PRACH的目标发射功率作为功率控制后的发射功率；如果不存在非 0的 w(i) (即 SRS功率降低为 0时剩余信道的发射功率之和还是超过用户设备允许的最大发射功率），则需进一步对具有次低优先级的信道 /信号进行等比例功率降低，例如根据公式（ 3 )对没有承载 UCI的 PUSCH等比例降低功率，其中 j为承载 UCI的 PUSCH的编号，以此类推，直到满足最大发射功率为止；具体的，此处，不存在 SRS和 PRACH传输，则首先对 PUSCH进行等比例功率降低，且其他上行信道 /信号仅包括前一个子帧中的上行信道，该时刻上，公式（ 3 ) 等效为 w(f) (A (f) - Y) _PUCCH , 得到功率降低后载波 1上 PUCCH的发射功率为 P_{PUCC 1} (z) = PUCC¾I( , 载波 2 上 PUSCH 的发射功率为 (1) Since there is no SRS transmission in this example, c ' is equal to o. In the formula, _c is the carrier number and i is the subframe number. Method 2: According to the channel/signal priority, the proportional power is reduced for multiple channels/signals with the lowest priority, ie: firstly reduce the power according to the formula (2) to the SRS (if there is SRS), if If there is a non-zero w(i), the power reduction ends, and the target transmit power of PUCCH, PUSCH, and PRACH is maintained as the transmit power after power control; if there is no non-zero w(i) (ie, the SRS power is reduced to 0) If the sum of the transmit powers of the remaining channels exceeds the maximum transmit power allowed by the user equipment, the channel/signal having the second lowest priority needs to be further reduced in proportion, for example, according to formula (3), the PUSCH without UCI is carried. Proportionally reduce power, where j is the number of the PUSCH carrying the UCI, and so on, until the maximum transmit power is satisfied; specifically, here, if there is no SRS and PRACH transmission, the PUSCH is firstly reduced in power, and the other uplink channel / uplink channel signal includes only the previous subframe, the time, equation (3) is equivalent to w (f) (a (f ) - Y) PUCCH, power to give 1 the PUCCH on the lower carrier transmit power _{P PUCC 1 (z) = PUCC¾I} (, 2 on PUSCH transmit power of the carrier

进一步，按照 TA从大到小的顺序，确定对具有次大 TA的载波 3、 4和 5上的上行信道集合进行功率控制：功率控制需要当前时刻上与当前上行信道 /信号集合中的上行信道 / 信号同时传输的其他上行信道 /信号的发射功率，其他上行信道包括当前上行子帧中至少与上行信道 /信号集合中的上行信道 /信号的部分符号同时传输的已经经过功率控制的上行信道 /信号，和 /或当前上行子帧的前一个相邻子帧中在初始发送时刻上存在传输的上行信道 / 信号，此处其他上行信道主要指当前上行子帧中至少与上行信道 /信号集合中的上行信道 / 信号的部分符号同时传输的已经经过功率控制的上行信道 /信号，由于载波 3、 4和 5上的 PUCCH和 PUSCH初始发送时刻上，同时存在载波 1上的 PUCCH传输以及载波 2上的 PUSCH传输，且其发射功率已经在上述步骤中确定，即此处的其他上行信道 /信号即为当前子帧中载波 3、 4和 5上的 PUCCH和 PUSCH, 则用户设备判断在该发送时刻上，载波 3、 4和 5上的 PUSCH的发射功率以及载波 1上的 PUCCH、载波 2上的 PUSCH根据上述步骤确定的发射功之和是否超过用户设备允许的最大发射功率 ^{5 CMAX}。当判断

Further, power control is performed on the uplink channel set on carriers 3, 4, and 5 having the second largest TA according to the order of TA from large to small: Power control requires an uplink channel in the current uplink channel/signal set at the current time. / transmit power of other uplink channels/signals simultaneously transmitted by the signal, and other uplink channels including at least the current uplink subframe The uplink channel/signal of the uplink channel/signal set in the upstream channel/signal set has been transmitted through the power-controlled uplink channel/signal, and/or the previous neighboring subframe of the current uplink subframe has been transmitted at the initial transmission time. Upstream channel/signal, where other uplink channels mainly refer to the already-powered uplink channel/signal that is simultaneously transmitted in at least the uplink channel/signal part of the uplink channel/signal set in the current uplink subframe, due to carrier 3, At the initial transmission timings of PUCCH and PUSCH on 4 and 5, there are both PUCCH transmission on carrier 1 and PUSCH transmission on carrier 2, and the transmission power thereof has been determined in the above steps, that is, other uplink channels/signals here are For the PUCCH and the PUSCH on the carriers 3, 4, and 5 in the current subframe, the user equipment determines the transmit power of the PUSCH on the carriers 3, 4, and 5 and the PUCCH and carrier 2 on the carrier 1 at the transmission time. Whether the sum of the transmit powers determined by the PUSCH according to the above steps exceeds the maximum transmit power allowed by the user equipment, ^{5 CMAX} . When judged

载波 3、 4和 5上的 PUSCH进行功率控制，具体方法如下： The PUSCH on carriers 3, 4, and 5 performs power control as follows:

釆用方法 1 : 根据公式（1 ), 对上述上行信道 /信号集合中的所有信道 /信号等比例降低功率；即此处不存在 SRS和 PRACH传输，且其他上行信道 /信号仅包括当前子帧中的上行信道，公式（ 1 )等效为

满足该公式的 w①值，从而确定功率降低后载波 3上 PUSCH的发射功率为 ^puscHW^; , 载波 4上 PUSCH的发射功率为 ^PUSCH'⁴ (^Ζ) , 载波 5上 PUSCH的发射功率为 ^Ρρυ3σι'⁵ (^Ζ) , 并作为实际发送功率； Method 1: According to formula (1), the power is reduced in proportion to all channels/signals in the above uplink channel/signal set; that is, there is no SRS and PRACH transmission, and other uplink channels/signals only include the current subframe. In the upstream channel, the formula (1) is equivalent to

The w1 value of the formula is satisfied, so that the transmit power of the PUSCH on the carrier 3 after the power reduction is determined to be ^puscH W ^; the transmit power of the PUSCH on the carrier 4 is ^PUSCH' ⁴ ( ^Ζ ), and the transmit power of the PUSCH on the carrier 5 is ^Ρρυ3σι ' ⁵ ( ^Ζ ) and as the actual transmit power;

釆用方法 2: 按照信道 /信号优先级，对具有最低优先级的多个信道 /信号进行等比例功率降低，即：首先根据公式（2 )对 SRS (如果存在 SRS )等比例降低功率，如果存在非 0 的 w(i) , 则功率降低结束，保持 PUCCH、 PUSCH和 PRACH的原始发射功率作为功率控制后的发射功率；如果不存在非 0的 w(i) (即 SRS功率降低为 0时剩余信道的发射功率之和还是超过用户设备允许的最大发射功率），则需进一步对具有次低优先级的信道 /信号进行等比例功率降低，例如根据公式（ 3 )对没有承载 UCI的 PUSCH等比例降低功率，其中 j为承载 UCI的 PUSCH的编号，以此类推，直到满足最大发射功率为止；具体的，此处，不存在 SRS和 PRACH传输，则首先对 PUSCH进行等比例功率降低，且其他上行信道 /信号仅包括当前子帧中的上行信道，该时刻上，公式（ 3 ) 等效为 Method 2: According to the channel/signal priority, the proportional power is reduced for multiple channels/signals with the lowest priority, ie: firstly reduce the power according to the formula (2) to the SRS (if there is SRS), if If there is a non-zero w(i), the power reduction ends, and the original transmit power of PUCCH, PUSCH, and PRACH is maintained as the transmit power after power control; if there is no non-zero w(i) (ie, the SRS power is reduced to 0) If the sum of the transmit powers of the remaining channels exceeds the maximum transmit power allowed by the user equipment, the channel/signal having the second lowest priority needs to be further reduced in proportion, for example, according to formula (3), the PUSCH without UCI is carried. Proportionally reduce power, where j is the number of the PUSCH carrying the UCI, and so on, until the maximum transmit power is satisfied; specifically, here, if there is no SRS and PRACH transmission, the PUSCH is firstly reduced in power, and the other The uplink channel/signal only includes the uplink channel in the current subframe. At this moment, equation (3) is equivalent to

用户设备按照上述确定的发射功率，在子帧 i中不同载波上同时发送各上行信道 /信号。需要说明的是，上述实施例中将用户设备允许的最大发射功率替换为频带允许的最大发射功率同样适用，即当上述 5个载波处于同一频带时，同样可根据上述方案基于频带允许的最大发射功率进行功率降低 , 以保证功率降低后的各信道 /信号发射功率之和不超过频带允许的最大发射功率；如果 UE还同时工作在其他频带中的载波，每个频带都可分别沿用上述方法基于频带允许的最大发射功率进行功率降低。需要说明的是， PUCCH不存在时，上述 ^P ccff =₀ , PUSCH不存在时，上述 ^P scff =₀ , The user equipment simultaneously transmits each uplink channel/signal on different carriers in the subframe i according to the transmission power determined above. It should be noted that, in the foregoing embodiment, the maximum transmit power allowed by the user equipment is replaced by the maximum transmit power allowed by the frequency band, that is, when the five carriers are in the same frequency band, the maximum transmission allowed based on the frequency band may also be used according to the foregoing solution. The power is reduced in power to ensure that the sum of the channel/signal transmission power after the power reduction does not exceed the maximum transmission power allowed by the frequency band; if the UE also works on carriers in other frequency bands, each frequency band can be respectively used based on the above method. The maximum transmit power allowed by the frequency band is used for power reduction. It should be noted that when PUCCH does not exist, when ^P ccff = ₀ and PUSCH does not exist, the above ^P scff = ₀ ,

SRS 不存在时，上述 ^PSRS =O, 同样适用；变更上述上行信道 /信号所在载波或者上行信道 / 信号类型，上述方法同样适用，例如上述 PUSCH替换为 PUCCH或 PRACH或 SRS或其他上行信道 /信号，或者上述 PUCCH替换为 PUSCH或 PRACH或 SRS或其他上行信道 / 信号。 When SRS does not exist, the above ^P SRS =O, the same applies. The above method is also applicable to change the carrier or uplink channel/signal type of the uplink channel/signal, for example, the PUSCH is replaced by PUCCH or PRACH or SRS or other uplink channel/signal. Or, the above PUCCH is replaced with a PUSCH or PRACH or SRS or other uplink channel/signal.

参见图 4, 本实施例中优先对 PUCCH进行功率控制的方法流程如下： Referring to FIG. 4, the method for preferentially controlling the power of the PUCCH in this embodiment is as follows:

步骤 401 :用户设备确定当前上行子帧中各载波的每个上行信道 /信号的目标发射功率。步骤 402: 用户设备确定当前上行子帧中存在 PUCCH传输，优先对 PUCCH进行功率控制。 Step 401: The user equipment determines a target transmit power of each uplink channel/signal of each carrier in the current uplink subframe. Step 402: The user equipment determines that PUCCH transmission exists in the current uplink subframe, and performs power control on the PUCCH preferentially.

步骤 403：按照 TA从大到小的顺序，用户设备判断当前子帧中未进行功率控制的具有最大 TA 的载波上的上行信道 /信号集合与在上行信道 /信号集合至少一个符号上同时传输的当前子帧中上行信道 /信号，以及在上行信道 /信号集合的初始发送时刻上同时传输的前一相邻子帧中的上行信道 /信号的发射功率之和是否超过预设的最大发射功率，若是，则继续步骤 404 , 否则继续步骤 405。 Step 403: The user equipment determines, according to the order of TA from large to small, that the uplink channel/signal set on the carrier with the largest TA that is not subjected to power control in the current subframe is simultaneously transmitted on at least one symbol of the uplink channel/signal set. Whether the sum of the uplink channel/signal in the current subframe and the transmit power of the uplink channel/signal in the previous adjacent subframe simultaneously transmitted at the initial transmission timing of the uplink channel/signal set exceeds a preset maximum transmit power, If yes, proceed to step 404, otherwise proceed to step 405.

步骤 404:用户设备对当前具有最大 TA的载波上的上行信道 /信号集合进行功率控制，使其与在上行信道 /信号集合至少一个符号上同时传输的当前子帧中上行信道 /信号，以及在上行信道 /信号集合的初始发送时刻上同时传输的前一相邻子帧中的上行信道 /信号的发射功率之和不超过预设的最大发射功率。 Step 404: The user equipment performs power control on the uplink channel/signal set on the carrier that currently has the largest TA, and makes the uplink channel/signal in the current subframe simultaneously transmitted on at least one symbol of the uplink channel/signal set, and The sum of the transmit powers of the uplink channels/signals in the previous adjacent subframe simultaneously transmitted at the initial transmission time of the uplink channel/signal set does not exceed the preset maximum transmit power.

步骤 405: 用户设备将当前具有最大 TA的载波的上行信道 /信号集合中各上行信道 /信号的目标发射功率作为实际发射功率。 Step 405: The user equipment sends each uplink channel/letter in the uplink channel/signal set of the carrier that currently has the largest TA. The target transmission power of the number is taken as the actual transmission power.

步骤 406: 按照 TA从大到小顺序，用户设备继续对当前子帧中未进行功率控制的上行信道 /信号重复步骤 403进行功率控制，直至满足当前子帧内任意时刻用户设备的总发射功率均不超过预设的最大发射功率。 Step 406: According to the order of the TAs from large to small, the user equipment continues to perform power control on the uplink channel/signal repetition step 403 in the current subframe without power control until the total transmission power of the user equipment is satisfied at any time in the current subframe. Does not exceed the preset maximum transmit power.

例如，参见图 5所示的传输示意图。用户设备聚合了 4个载波进行上行传输，由于 TA 不同，载波 2的上行发送时间较载波 1提前 1个 SC-FDMA符号，载波 3和 4的上行发送时间较载波 1推后 1个 SC-FDMA符号，传输情况如图 5所示，用户设备确定子帧 i中信道的发射功率的具体行为如下： For example, see the transmission diagram shown in Figure 5. The user equipment aggregates 4 carriers for uplink transmission. Because the TA is different, the uplink transmission time of carrier 2 is 1 SC-FDMA symbol ahead of carrier 1. The uplink transmission time of carriers 3 and 4 is 1 SC-FDMA after carrier 1 is pushed. Symbol, transmission situation As shown in Figure 5, the specific behavior of the user equipment to determine the transmission power of the channel in subframe i is as follows:

用户设备首先根据背景技术部分介绍的相关公式分别计算得到载波 1上 PUCCH的发射功率 ^PPUCC ₁ )、载波 2上承载 UCI的 PUSCH的发射功率 ^PpuscH'²(^Z)、载波 3上未承载 UCI的 PUSCH的发射功率 ^PpuscH'³ (^Z)、载波 4上未承载 UCI的 PUSCH的发射功率 ^PpuscH'⁴(^Z) , 并根据 Ρχ = ^10¾/1°确定其线性域值。 User equipment first The formula for the Background section describes are calculated on the carrier 1 PUCCH transmission power ^{P PUCC} _1), the carrier 2 bearing the UCI PUSCH transmit power ^PpuscH ^'2 ^(Z), is not carried UCI on carrier 3 The transmit power ^PpuscH ' ³ ( ^Z ) of the PUSCH, the transmit power ^PpuscH ' ⁴ ( ^Z ) of the PUSCH carrying the UCI on the carrier 4, and its linear domain value is determined according to Ρχ = ^103⁄4/1 °.

由于当前子帧中载波 1上存在 PUCCH传输，终端首先对该 PUCCH进行功率控制，以确定该 PUCCH的传输功率，具体方式有：方法 A: 保持该 PUCCH发送功率不降低，即 ^PUCCH'¹ (^Ζ) = ^Ρρυα¾1 (^Ζ) , 由于在该 PUCCH 的初始传输时刻上载波 4上存在前一个子帧中的 PUSCH传输，则用户设备确定该前一个子帧中的 PUSCH与该当前子帧的 PUCCH重叠部分的发射功率为 0,或者前一个子帧中的 Because the PUCCH transmission exists on the carrier 1 in the current subframe, the terminal first performs power control on the PUCCH to determine the transmission power of the PUCCH. The specific manner is as follows: Method A: Keep the PUCCH transmission power from decreasing, that is, ^PUCCH' ¹ ( ^Ζ ) = ^{Ρρυα3⁄41} ( ^Ζ ), since there is a PUSCH transmission in the previous subframe on the carrier 4 at the initial transmission timing of the PUCCH, the user equipment determines that the PUSCH in the previous subframe overlaps with the PUCCH of the current subframe. Part of the transmit power is 0, or in the previous sub-frame

PUSCH的发射功率为 ^PCMAX I、_P_PU_CCI I、 , 以满足该时刻总发射功率不超过用户设备允许的最大发射功率 ^{5 CMAX}。 The transmit power of the PUSCH is ^P CMAX I, _P _P U _CC II , to meet the total transmit power at this time does not exceed the maximum transmit power allowed by the user equipment ^{5 CMAX} .

方法 B：根据在该 PUCCH的初始传输时刻上载波 4上的前一个子帧中的 PUSCH传输的发射功率 ^PpUSCH'⁴(^Z , 降低 PUCCH的发射功率为 uCCH,¹ (；) = ^P MAX (0 - PpUSCHA - , 以满足该时刻总发射功率不超过用户设备允许的最大发射功率。 Method B: According to the transmission power ^PpUSCH ' ⁴ of the PUSCH transmission in the previous subframe on the carrier 4 at the initial transmission timing of the PUCCH ( ^Z , the transmission power of the PUCCH is reduced to uCCH, ¹ (;) = ^P MAX (0 - PpUSCHA - , to meet the total transmit power at this time does not exceed the maximum transmit power allowed by the user equipment.

然后，按照 TA从大到小的顺序，首先确定对具有最大 TA的载波 2上的上行信道进行功率控制：功率控制需要当前时刻上与当前上行信道 /信号集合中的上行信道 /信号同时传输的其他上行信道 /信号的发射功率，其他上行信道包括当前上行子帧中至少与上行信道 /信号集合中的上行信道 /信号的部分符号同时传输的已经经过功率控制的上行信道 /信号，和 /或当前上行子帧的前一个相邻子帧中在初始发送时刻上存在传输的上行信道 /信号。 Then, according to the order of TA from large to small, firstly, power control is performed on the uplink channel on carrier 2 having the largest TA: power control needs to be simultaneously transmitted with the uplink channel/signal in the current uplink channel/signal set at the current time. The transmit power of other uplink channels/signals, the other uplink channels include the power-controlled uplink channels/signals that are simultaneously transmitted in at least the uplink symbols of the uplink channel/signal in the uplink channel/signal set, and/or There is a transmitted uplink channel/signal at the initial transmission time in the previous adjacent subframe of the current uplink subframe.

具体而言，在载波 2的 PUSCH初始发送时刻上，同时存在子帧 i-1中载波 1上的 PUCCH 传输，且其功率已经确定为 ^P ₁ (^z - ¹) , 以及子帧 i—i中载波 4上的 PUSCH传输，且其功率已经确定为^^∞<¾4(^{7 _ 1}) , 考虑到本子帧 i 中也存在 PUCCH传输且与载波 2 上的 Specifically, at the PUSCH initial transmission timing of the carrier 2, there is simultaneously the PUCCH on the carrier 1 in the subframe i-1. Transmission, and its power has been determined to be ^P ₁ ( ^z - ¹ ), and PUSCH transmission on carrier 4 in subframe i-i, and its power has been determined to be ^ ^{∞ < 3⁄44} ( ^{7 _ 1} ), considering this subframe PUCCH transmission also exists in i and on carrier 2

PUSCH在部分符号上存在同时传输，且其功率已经确定为 ^ '¹ (^Ζ) , 则用户设备首先比较这两个 PUCCH的发射功率，以具有最大发射功率的 PUCCH的发射功率为准进行功率控制，进而用户设备判断在该发送时刻上，具有最大发射功率的 PUCCH、载波 2 上的 PUSCH以及载波 4在子帧 i-1 的 PUSCH的发射功率之和是否超过用户设备允许的最大发射功率 P_CMAX , 当判断

(0 时，需要对载波 2上的 PUSCH进行功率降低，具体方法如下： The PUSCH has simultaneous transmission on part of the symbols, and its power has been determined to be ^ ' ¹ ( ^Ζ ). Then, the user equipment first compares the transmission powers of the two PUCCHs, and performs power control based on the transmission power of the PUCCH having the largest transmission power. the PUCCH, and further the user equipment determines the transmission timing, having the maximum transmit power, the PUSCH and the carrier on the carrier 24 in the transmission power of the sub-frame i-1 PUSCH to and exceeds a user equipment allowed maximum transmission power P _CM AX, when judging

釆用方法 2: 具体方案同图 2和图 3所示的实施例中的描述，公式（2 )和（3 )等效为公式（ 5 )和（ 6 ), 即：首先根据公式（ 5 )对 SRS (如果存在 SRS )等比例降低功率，如果存在非 0的 w(i), 则功率降低结束，保持 PUCCH、 PUSCH和 PRACH的目标发射功率作为功率控制后的发射功率；如果不存在非 0的 w(i) (即 SRS功率降低为 0时剩余信道的发射功率之和还是超过用户设备允许的最大发射功率），则需进一步对具有次低优先级的信道 /信号进行等比例功率降低，例如根据公式（ 6 )对没有承载 UCI的 PUSCH等比例降低功率，其中 j为承载 UCI的 PUSCH的编号，以此类推，直到满足最大发射功率为止；具体的，此处，不存在 SRS和 PRACH传输，则首先对 PUSCH进行等比例功率降低，且其他上行信道 /信号包括前一个子帧中的载波 4上的 PUSCH, 以及前一个子帧中和当前子帧中具有较大发射功率的 PUCCH , 该时刻上，公式（ 6 ) 等效为方法 Method 2: The specific scheme is the same as the description in the embodiment shown in FIG. 2 and FIG. 3, and equations (2) and (3) are equivalent to equations (5) and (6), namely: first according to formula (5) For SRS (if there is SRS), the power is reduced proportionally. If there is non-zero w(i), the power reduction ends, and the target transmit power of PUCCH, PUSCH, and PRACH is maintained as the transmit power after power control; if there is no non-zero w(i) (ie, the sum of the transmit powers of the remaining channels when the SRS power is reduced to 0 is still greater than the maximum transmit power allowed by the user equipment), and further equal power reduction is required for the channel/signal having the second lowest priority. For example, according to the formula (6), the power is reduced in proportion to the PUSCH that does not carry the UCI, where j is the number of the PUSCH carrying the UCI, and so on, until the maximum transmit power is satisfied; specifically, there is no SRS and PRACH transmission. , first, the equal power reduction of the PUSCH is performed, and The other uplink channel/signal includes the PUSCH on the carrier 4 in the previous subframe, and the PUCCH in the previous subframe and the larger transmission power in the current subframe.

进一步，按照 TA从大到小的顺序，用户设备确定对具有次大 TA的载波上的上行信道集合进行功率控制：由于该次大 TA下仅存在载波 1上的 PUCCH传输，其发射功率已经确定，无需再一次确定。 Further, in order of the TA from large to small, the user equipment determines to perform power control on the uplink channel set on the carrier with the second largest TA: since only the PUCCH transmission on the carrier 1 exists in the secondary large TA, the transmit power has been determined. , no need to determine again.

进一步，按照 TA从大到小的顺序，终端确定对具有较小 TA的载波上的上行信道集合进行功率控制：功率控制需要当前时刻上与当前上行信道 /信号集合中的上行信道 /信号同时传输的其他上行信道 /信号的发射功率，其他上行信道包括当前上行子帧中至少与上行信道 /信号集合中的上行信道 /信号的部分符号同时传输的已经经过功率控制的上行信道 /信号，和 /或当前上行子帧的前一个相邻子帧中在初始发送时刻上存在传输的上行信道 /信号。 Further, according to the order of TA from large to small, the terminal determines to perform power control on the uplink channel set on the carrier with the smaller TA: The power control needs to transmit simultaneously with the uplink channel/signal in the current uplink channel/signal set at the current time. The transmit power of the other uplink channel/signal, the other uplink channel includes the power-controlled uplink channel/signal that is simultaneously transmitted with at least the partial symbol of the uplink channel/signal in the uplink channel/signal set in the current uplink subframe, and/ Or there is a transmitted uplink channel/signal at the initial transmission time in the previous adjacent subframe of the current uplink subframe.

具体而言，对于载波 3和 4上的 PUSCH传输，在载波 3和 4上的 PUSCH初始发送时刻上，同时存在载波 1上的 PUCCH传输以及载波 2上的 PUSCH传输，且其发射功率已经在上述步骤中确定，即此处的其他上行信道 /信号即为当前子帧中载波 1 和载波 2上的 PUCCH和 PUSCH, 则用户设备判断在该发送时刻上，载波 3和 4上的 PUSCH的发射功率以及载波 1上的 PUCCH、载波 2上的 PUSCH根据上述步骤确定的发射功率之和是否超过用户设备允许的最大发射功率 ^PcMAX。当判断 PpUSCH ,3 (0 + PpUSCH ('') + PpUCCH ,\ (0 + PpUSCH ,2 (0 > ^CMAX ( 时 , 需要对载波 3和 4 上的 PUSCH进行功率降低，具体方法如下： Specifically, for the PUSCH transmission on the carriers 3 and 4, on the initial transmission timing of the PUSCH on the carriers 3 and 4, there are both the PUCCH transmission on the carrier 1 and the PUSCH transmission on the carrier 2, and the transmission power thereof is already above. It is determined in the step that the other uplink channel/signal is the PUCCH and the PUSCH on the carrier 1 and the carrier 2 in the current subframe, and the user equipment determines the transmit power of the PUSCH on the carriers 3 and 4 at the transmission time. And whether the sum of the transmit powers determined by the PUCCH on the carrier 1 and the PUSCH on the carrier 2 according to the above steps exceeds the maximum transmit power ^PcMAX allowed by the user equipment. When judging PpUSCH, 3 (0 + PpUSCH ('') + PpUCCH , \ (0 + PpUSCH , 2 (0 > ^CMAX), the power of the PUSCH on carriers 3 and 4 needs to be reduced. The specific method is as follows:

釆用方法 1 : 根据公式（4 ), 对上述上行信道 /信号集合中的所有信道 /信号等比例降低功率；即此处不存在 SRS和 PRACH传输，且其他上行信道 /信号仅包括当前子帧中的上行信道，公式（4 )等效为后载波 3上 PUSCH的发射功率为 ^puscH'^{3 l)} , 载波 4上 PUSCH的发射功率为 ^puscH'^{4 l)} , 并作为实际发送功率。 Method 1: According to formula (4), the power is reduced in proportion to all channels/signals in the above uplink channel/signal set; that is, there is no SRS and PRACH transmission, and other uplink channels/signals only include the current subframe. Upstream The channel, Equation (4) is equivalent to the transmission power of the PUSCH on the rear carrier 3 is ^puscH ' ^{3 l)} , and the transmission power of the PUSCH on the carrier 4 is ^puscH ' ^{4 l)} , and is used as the actual transmission power.

釆用方法 2: 按照信道 /信号优先级，对具有最低优先级的多个信道 /信号进行等比例功率降低，即：首先根据公式（ 5 )对 SRS (如果存在 SRS )等比例降低功率，如果存在非 0 的 w(i), 则功率降低结束，保持 PUCCH、 PUSCH和 PRACH的原始发射功率作为功率控制后的发射功率；如果不存在非 0的 w(i) (即 SRS功率降低为 0时剩余信道的发射功率之和还是超过用户设备允许的最大发射功率），则需进一步对具有次低优先级的信道 /信号进行等比例功率降低，例如根据公式（ 6 )对没有承载 UCI的 PUSCH等比例降低功率，其中 j为承载 UCI的 PUSCH的编号，以此类推，直到满足最大发射功率为止；具体的，此处，不存在 SRS和 PRACH传输，则首先对 PUSCH进行等比例功率降低，且其他上行信道 /信号仅包括当前子帧中的上行信道，该时刻上，公式（ 6 ) 等效为 Method 2: According to the channel/signal priority, the proportional power is reduced for multiple channels/signals with the lowest priority, ie: firstly reduce the power according to the formula (5) to SRS (if there is SRS), if If w(i) is non-zero, the power reduction ends, and the original transmit power of PUCCH, PUSCH, and PRACH is maintained as the transmit power after power control; if there is no non-zero w(i) (ie, the SRS power is reduced to 0) If the sum of the transmit powers of the remaining channels exceeds the maximum transmit power allowed by the user equipment, the channel/signal having the second lowest priority needs to be further reduced in proportion, for example, according to formula (6), the PUSCH without UCI is carried. Proportionally reduce power, where j is the number of the PUSCH carrying the UCI, and so on, until the maximum transmit power is satisfied; specifically, here, if there is no SRS and PRACH transmission, the PUSCH is firstly reduced in power, and the other The uplink channel/signal only includes the uplink channel in the current subframe. At this moment, equation (6) is equivalent to

功率降低，确定按照每个载波上的功率控制公式计算得到的发射功率即为实际发送功率 ,

The power is reduced, and the transmit power calculated according to the power control formula on each carrier is determined as the actual transmit power.

用户设备按照上述确定的发射功率，在子帧 i中不同载波上同时发送各上行信道 /信号。需要说明的是，上述实施例中将用户设备允许的最大发射功率替换为频带允许的最大发射功率同样适用，即当上述 4个载波处于同一频带时，同样可根据上述方案基于频带允许的最大发射功率进行功率降低 , 以保证功率降低后的各信道 /信号发射功率之和不超过频带允许的最大发射功率；如果 UE还同时工作在其他频带中的载波，每个频带都可分别沿用上述方法基于频带允许的最大发射功率进行功率降低。需要说明的是， PUCCH不存在时，上述 ^P ccff =₀ , PUSCH不存在时，上述 ^P scff =₀ , SRS 不存在时，上述 ^PSRS =O, 同样适用；变更上述上行信道 /信号所在载波或上行信道 /信号类型，上述方法同样适用，例如上述 PUSCH替换为 PUCCH或 PRACH或 SRS或其他上行信道 /信号，或者上述 PUCCH替换为 PUSCH或 PRACH或 SRS或其他上行信道 /信号。 The user equipment simultaneously transmits each uplink channel/signal on different carriers in the subframe i according to the transmission power determined above. It should be noted that, in the foregoing embodiment, the maximum transmit power allowed by the user equipment is replaced by the maximum transmit power allowed by the frequency band, that is, when the four carriers are in the same frequency band, the maximum transmission allowed based on the frequency band may also be used according to the foregoing solution. The power is reduced in power to ensure that the sum of the channel/signal transmission power after the power reduction does not exceed the maximum transmission power allowed by the frequency band; if the UE also works on carriers in other frequency bands, each frequency band can be respectively used based on the above method. The maximum transmit power allowed by the frequency band is used for power reduction. It should be noted that when PUCCH does not exist, when ^P ccff = ₀ and PUSCH does not exist, when ^P scff = ₀ and SRS does not exist, the above ^P SRS = O, the same applies; change the carrier of the uplink channel/signal or For the uplink channel/signal type, the above method is also applicable, for example, the PUSCH is replaced by PUCCH or PRACH or SRS or other uplink channel/signal, or the PUCCH is replaced by PUSCH or PRACH or SRS or other uplink channel/signal.

通过以上描述了解了依据 TA顺序进行上行功率控制的实现方式，该过程主要由用户设备实现，下面对用户设备的内部结构和功能进行介绍。 Through the above description, the implementation manner of uplink power control according to the TA sequence is understood, and the process is mainly performed by the user. Device implementation, the internal structure and function of the user equipment are introduced below.

参见图 6, 本实施例中用户设备包括：功率计算模块 601和功率控制模块 602。 Referring to FIG. 6, the user equipment in this embodiment includes: a power calculation module 601 and a power control module 602.

功率计算模块 601 用于确定当前上行子帧中传输的每个上行信道 /信号的目标发射功率。 The power calculation module 601 is configured to determine a target transmit power of each uplink channel/signal transmitted in the current uplink subframe.

功率控制模块 602 用于根据当前上行子帧中传输的每个上行信道 /信号所在的上行载波的上行发送时间提前量，按照上行发送时间提前量从大到小的顺序，对当前上行子帧中传输的上行信道 /信号的目标发射功率进行功率控制，以满足功率控制后，用户设备在当前上行子帧中任意时刻的总发射功率不超过预设的最大发射功率。 The power control module 602 is configured to: according to the uplink transmission time advance of the uplink carrier where each uplink channel/signal transmitted in the current uplink subframe is located, in the current uplink subframe according to the uplink transmission time advance amount from the largest to the smallest The target transmit power of the transmitted uplink channel/signal is subjected to power control. After the power control is performed, the total transmit power of the user equipment at any time in the current uplink subframe does not exceed the preset maximum transmit power.

具体的，功率控制模块 602按照上行发送时间提前量从大到小的顺序，逐一确定一个具有相同上行发送时间提前量的未进行功率控制的上行信道 /信号集合，上行信道 /信号集合包括至少一个上行信道 /信号，根据上行信道 /信号集合的初始发送时刻上与该上行信道 / 信号集合同时传输的其他上行信道 /信号的发射功率，对上行信道集合中的上行信道 /信号的目标发射功率进行功率控制，以满足功率控制后，初始发送时刻上，用户设备的总发射功率不超过预设的最大发射功率，其中总发射功率为上行信道 /信号集合中的各上行信道 / 信号的发射功率与其他上行信道 /信号的发射功率之和。 Specifically, the power control module 602 determines, according to the order of the uplink transmission time advancement, an uplink channel/signal set that has no power control and has the same uplink transmission time advance quantity, and the uplink channel/signal set includes at least one. The uplink channel/signal, according to the transmit power of the other uplink channel/signal simultaneously transmitted with the uplink channel/signal set at the initial transmission time of the uplink channel/signal set, performs the target transmit power of the uplink channel/signal in the uplink channel set. After the power control is performed, the total transmit power of the user equipment does not exceed the preset maximum transmit power at the initial transmission time, where the total transmit power is the transmit power of each uplink channel/signal in the uplink channel/signal set and The sum of the transmit powers of other upstream channels/signals.

优选的，功率控制模块 602判断初始发送时刻上，上行信道 /信号集合中的各上行信道 /信号的目标发射功率与其他上行信道 /信号的发射功率之和是否超过预设的最大发射功率； Preferably, the power control module 602 determines whether the sum of the target transmit power of each uplink channel/signal and the transmit power of the other uplink channel/signal in the uplink channel/signal set exceeds a preset maximum transmit power at the initial transmission time;

当判断超过预设的最大发射功率时，功率控制模块 602对上行信道 /信号集合中的上行信道 /信号的目标发射功率进行功率控制，以满足功率控制后，上行信道 /信号集合中的各上行信道 /信号的发射功率之和不超过当前可用最大发射功率，当前可用最大发射功率为预设的最大发射功率减去其他上行信道的发射功率； When it is determined that the preset maximum transmit power is exceeded, the power control module 602 performs power control on the target transmit power of the uplink channel/signal in the uplink channel/signal set to satisfy each uplink in the uplink channel/signal set after power control. The sum of the transmission powers of the channels/signals does not exceed the currently available maximum transmit power, and the currently available maximum transmit power is the preset maximum transmit power minus the transmit power of the other uplink channels;

当判断未超过预设的最大发射功率时，功率控制模块 602确定上行信道 /信号集合中的各上行信道 /信号的目标发射功率为功率控制后各上行信道 /信号的发射功率。 When it is determined that the preset maximum transmit power is not exceeded, the power control module 602 determines that the target transmit power of each uplink channel/signal in the uplink channel/signal set is the transmit power of each uplink channel/signal after power control.

较佳地功率控制方式有： The preferred power control methods are:

Decrease, the target transmit power of the channel/signal in different frequency bands having the same channel/signal priority in the uplink channel/signal set is reduced according to the power reduction ratio coefficient corresponding to the frequency band, and the uplink channel after power control is obtained/ The transmit power of the signal, wherein, for the uplink channel/signal power with a power reduction proportional coefficient of 1, the target transmit power is determined to be the transmit power after power control, and the target transmit power is determined for the uplink channel/signal that does not require power reduction. The power of the transmission after power control.
