背景技术
IAB(Integrated access backhaul,综合接入回程)作为中继,需要处理回程(Backhaul)链路的信号和接入(Access)链路的信号。如图1所示,DB(Downlink Backhaul,下行回程)链路和UA(Uplink access,上行接入)链路可以通过FDM/SDM(frequency division multiplexing/spatial division multiplexing,频分复用/空分复用)的方式同时接收,或者UB(Uplink Backhaul上行回程)链路和DA(Downlink access下行接入)链路可以通过FDM/SDM的方式发送。同时传输的信号需要考虑他们的功率共享问题,比如UB和DA共享一个功放的时候,需要考虑两个信号之间的功率共享问题。另一方面,在两个链路上同时传输的信号,由于一个是基站发送的,一个是终端发送的,或者由于Backhaul链路的调度是图1中的IAB node1(节点1)/IAB donor node(主节点)控制的,Access链路的调度是由IAB node2(节点2)控制的,从而两个信号的发送功率不对等,就会造成比较强的干扰,两个链路上同时传输的信号的干扰问题也是需要进一步考虑的问题。因此,如何确定功率信息成为一个亟待解决的问题。

具体实施方式
图1中的UB链路和DA链路频分复用如图2所示,或者图1中的UB链路和DA链路空分复用如图3所示时,图3中UB和DA在相同时间占有的频域资源有部分重叠,本实施例中,UB和DA空分复用的时候,也不排除UB和DA在相同时间占有的频域资源完全重叠。特别是频域复用或者空分复用的多个波束共享一个功放时,需要考虑两个链路之间的功率共享问题,比如在图2或者图3中,UB的发送功率需要受到DA链路的发送功率的影响。即使不共享功放,但是由于图1中的IAB处发出的信号总功率有限制时,比如UB和DA从IAB node2处发出的总功率不能超过预定门限,此时也需要考虑UB发送功率和DA发送功率之间的影响。
另一方面即使空分复用或频分复用的两路信号不共享功率,总功率也不受 限,比如UB和DA分别对应IAB node2的两个独立的功放,但是两个空分复用的链路如果发送功率不对等会导致干扰问题,如图3和图1所示,当UB和DA空分复用时,如果UB的发送功率远小于DA的发送功率,就会导致在IAB donor node/IAB node1处DA对于UB信号的干扰比较大。类似地如果UB的发送功率大于DA的发送功率就会导致在IAB node3/UE处,UB信号对于DA信号造成比较大的干扰。UB和DA频分复用的时候,虽然UB和DA频分复用占有不同的物理资源块,但是如果两个信号的功率相差很大,功率大的信号的功率泄露也会对另一个链路造成强干扰。
上行链路的功率信息一般是基站给终端发送功率控制信息,或者基站和终端约定特定功率信息的取值范围计算公式,终端在此范围取值都是合理的,当满足上报条件时,终端将最终选择的功率信息值上报给基站。即图1中的IAB donor node/IAB node1给IAB node2发送功率控制信息,参考协议38.213和协议38.331可以看到,基站给终端分配的上行信道的功率控制信息包括服务小区c中的载波f中的带宽部分b(Bandwidth part带宽部分)中的关于第j套功率参数中的:目标接收功率P O_PUSCH,b,f,c(j),路损调整因子α b,f,c(j),计算路损所参考的下行参考信号信息q d,功率调整参数δ PUSCH,b,f,c,功率进程l。上述需要多套功率控制信息,主要因为上行信道所用的波束组合不同导致的上行发送功率控制参数应该不同。在一实施例中,PUSCH的发送功率根据公式(1)获取。

是第i个PUSCH传输中第j个时域符号中一个PRB(Physical Resource Block,物理资源块)中除去解调参考信号之后的剩余的RE的个数,其他参数的意义可以参考协议38.213。
基站和终端约定公式(1)中的P CMAX,f,c(i)的满足如下公式(2)所示:
P CMAX_L,f,c≤P CMAX,f,c≤P CMAX_H,f,c      (2)
其中

P CMAX_H,f,c=MIN{P EMAX,c,P PowerClass–ΔP PowerClass}   (3-2)
多个参数的意义可以参考协议38.101-1。P CMAX,f,c(i)只要满足上述公式(2)中的范围就可以,P CMAX,f,c(i)值依赖于终端选择,当满足触发条件时,终端将选择的P CMAX,f,c(i)值上报给基站。
另一方面当满足触发条件时,终端向基站上报功率余量信息,其中功率余量信息可以采用如下公式(3-3)~(3-6)中的一种,

应用实施例一
在本实施例中,如果在IAB系统中继续沿用上报NR(Next generation radio)的功率控制系统,IAB donor node/IAB node1在分配UB-PUSCH的功率信息的时候,不会考虑与UB-PUSCH(Physical Uplink Shared Channel,物理上行共享信道)频分复用和/或空分复用的DA中的信道或信号的发送功率,为此可以有如下增强方案:
方案一:图1中的IAB node2向IAB donor node/IAB node1请求或反馈IAB node2希望UB-PUSCH的功率信息,其中IAB node2发送的请求信息中包括UB-PUSCH/UB-PUCCH/UB-SRS的如下信息至少之一:目标功率P O_PUSCH,b,f,c(j),路损调整因子α b,f,c(j),计算路损参考的下行参考信号q d,功率调整参数δ PUSCH,b,f,c。需要特别说明的一点的是,目标功率P O_PUSCH,b,f,c(j)由P O_NOMINAL_PUSCH,f,c(j),P O_UE_PUSCH,b,f,c(j)两部分构成,P O_NOMINAL_PUSCH,f,c(j)是Cell specific的参数,P O_UE_PUSCH,b,f,c(j)是UE-Specific的,而且UE的多个BWP可以不同,由于Cell specific的功率参数需要考虑这个CC下IAB donor node/IAB node1覆盖的所有UE,即使IAB node2请求,IAB donor node/IAB node1也不好调整,为此示例性地IAB node2可以向基站请求UE-Specific的参数P O_UE_PUSCH,b,f,c(j),IAB node2在IAB donor node/IAB node1看来是一种特殊的终端,IAB node2可以每个BWP都请求一个P O_UE_PUSCH,b,f,c(j),也可以只请求当前激活BWP的P O_UE_PUSCH,b,f,c(j)参数。
在一些实施例中,IAB node2向IAB donor node/IAB node1请求或反馈UB-PUSCH的功率信息时,可以请求或反馈两套功率信息,第一套中UB-PUSCH的功率信息获取参数中不包括DA信道或信号的功率信息,第二套中UB-PUSCH的功率信息获取参数中包括DA信道或信号的功率信息。
方案二:IAB node2向IAB donor node/IAB node1发送DA中的信道或信号的功率信息,示例性地DA是与UB空分复用或频分复用的DA。其中DA中的信道或信号的功率信息包括如下信息至少之一:发送功率,目标接收功率,DA的参考信号到达IAB node3/UE处的RSRP(reference signal received power)信息,DA的参考信号到达IAB node3/UE处的RSRQ(reference signal received quality)信息,DA中的参考信号到达IAB node3/UE处的CSI(channel state information)信息,DA参考信号到达IAB node3/UE处的RSRP/RSRQ与IAB donor node/IAB node1分配的UB信号在IAB donor/IAB node1处的目标接收功率P O_PUSCH,b,f,c(j)之间的差值。比如UB和DA共享IAB node2的功放,UB和DA通过数字波束空分复用,如果DA参考信号到达图1中的IAB node3/UE的性能比较好,IAB donor node/IAB node1就可以根据DA在IAB node3/UE处的接收性能调整UB的发送功率(比如通过信令调整UB发送功率的获取参数),从而在保证DA和UB空分复用的同时,使得DA和UB两个信号之间的相互干扰降低,因为DA和UB在图1中的IAB node2看来可以看为是两个做MU的下行用户,需要考虑他们的干扰问题,但是UB信号是由图1中的IAB donor node/IAB node1控制调度的,DA是由图1中的IAB node2调度,所以IAB node2需要向IAB donor node/IAB node1反馈DA的功率控制信息。
在上述方案一和方案二中,图1中的IAB node2向IAB donor node/IAB node1反馈或请求上述信息之后,IAB donor node/IAB node1就可以参考这些信息调整UB-PUSCH的功率,给UB-PUSCH分配功率控制信息,和/或IAB donor node/IAB node1与IAB node2可以和IAB node2约定IAB node2可以根据这些反馈信息获得UB-PUSCH的发送功率等。
方案三:IAB node2在计算公式(2)中的P CMAX,f,c的时候,考虑DA的影响,
例如在将上述公式(3-1)改为(4-1)和/或公式(3-2)改为(4-2):
P CMAX_L,f,c=MIN{P EMAX,c–ΔTC,c,(P PowerClass–ΔP PowerClass)–MAX(MPR c+A-MPR c+ΔT IB,cTC, c+P DA,P-MPR c)}   (4-1);
P CMAX_H,f,c=MIN{P EMAX,c,P PowerClass–ΔP PowerClass-P DA}   (4-2)。
其中P DA是UB-PUSCH所在的时域资源上的DA的信道或信号的发送功率。IAB node2根据公式(2)和公式(3-1)与(4-2)得到P CMAX,f,c,或者IAB node2根据公式(2)和公式(4-1)与(3-2)得到P CMAX,f,c,或者IAB node2根据公式(2)和公式(4-1)与(4-2)得到P CMAX,f,c。当满足上报条件时,IAB node2将选择的P CMAX,f,c值上报给IAB donor/IAB node1。
方案四:IAB node2在根据公式(3-3)~(3-6)之一计算功率余量(Power headroom PH)的时候,考虑DA信号的影响,比如将公式(3-3)改为公式(4-3):
Figure PCTCN2019099118-appb-000010
和/或将公式(3-4)改为公式(4-4)

方案五:IAB node2在计算UB-PUSCH的功率时,将公式(1)改为公式(5-1)
Figure PCTCN2019099118-appb-000014
其中P DA是UB-PUSCH所在的时域资源上,有DA信道和/或信号的PRB上的DA信道和/或信号的发送功率总和,比如P DA可以通过如下公式之一获取:
Figure PCTCN2019099118-appb-000015
P DA=f(PRB DA),(5-3)
P DA=f 1(PRB DA,c,DA CC),(5-4)
Figure PCTCN2019099118-appb-000016
其中PRB DA是UB所在的时域符号上存在DA信道或信号的PRB集合,或者PRB DA是与UB功率共享功放的带宽中DA的信道和/或信号占有的PRB,示例性 的,比如PRB DA包括一个Intra Band或者一个CC或者一个BWP中有DA信道和/或信号的PRB。P DA,r是第r个PRB上的图1中的IAB node2发送DA信道和/或信号的发送功率,或者P DA,r是一个时域符号上的第r个PRB上的图1中IAB node2发送DA信道和/或信号的发送功率。
Figure PCTCN2019099118-appb-000017
表示DA所在的CC c中包括的PRB个数,当UB所在的时域符号中DA所在CC c中的一个PRB r中没有DA信号需要发送的时候,P DA,r,c为0。上述DA信道和/或信号可能是发送给IAB node2覆盖下的多个UE/IAB node3的,也可以是给一个UE/IAB node3的。f(PRB DA)是关于PRB DA的函数,f 1(PRB DA,c,DA CC)是关于PRB DA,c,DA CC的函数,其中c∈DA CC,DA CC是UB所在的时域符号上存在DA信道和/或信号的CC的集合。
方案六:UB和DA的功率计算各自计算,当两者的总功率和大于约定值时,采用约定方法对UB和/或DA的功率进行缩减,实施方式可参考实施例三所示。
上述方案中描述的是UB-PUSCH的功率控制方法,类似地上述方案也适用于UB-PUCCH(Physical Uplink Control Channel,物理上行控制信道),UB-SRS(Sounding Reference Signal,探测参考信号)的功率控制。
应用实施例二
在本实施例中,根据如下方式至少之一确定功率的确定方式:接收的信令信息,发送的请求信息,A个链路之间的复用方式,A个链路中的信道或信号占有的频域资源是否有重叠,约定规则,B个链路中的信道或信号的功率总和和预定值之间的关系,A,B为大于1的正整数。
示例性的,比如UB链路的功率获取方式有如下两个公式(6-1)和(6-2),采用哪个公式,根据如下信息至少之一获取:IABnode2向IAB donor node/IAB node1发送的请求信息,IAB donor node/IAB node1向IAB node2发送的信令信息,UB和DA之间的复用方式信息,UB的信道或信号占有的PRB资源和DA的信道和/或信号占有的PRB资源之间是否有重叠,约定规则。

其中P DA是UB-PUSCH所在的时域资源上,有DA信道和/或信号的PRB上的DA信道和/或信号的发送功率总和,比如P DA可以通过公式(5-2)~(5-5)中的一种计算。
UB和DA频分复用的时候,只是UB的总功率受到DA的发送功率的影响,当UB和DA空分复用的时候,不仅UB的总功率受到DA的发送功率的影响,进一步如果要保证IAB node2发送的信道和/或信号在每个PRB中的总功率恒定,则UB的每个PRB的可用功率也受到DA的影响。所以公式(6-2)中在UB的每个PRB的功率计算中还要考虑DA的影响,如图8所示,是一种UB-PUSCH和存在DA信道和/或信号的示意图,UB-PUSCH占有{PRB1,PRB2,PRB3},在UB-PUSCH所在的时域符号上,存在DA的信道或信号的PRB为{PRB1,PRB3,PRB4~PRB8},从而在计算P DA的时候,可以根据{PRB1,PRB3,PRB4~PRB8}中信道和/或信号所占的功率进行计算,在计算UB-PUSCH每个PRB的发送功率的时候,可以考虑该PRB上DA的信道和/或信号占有的发送功率。
Figure PCTCN2019099118-appb-000021
表示在UB-PUSCH占有的{PRB1,PRB2,PRB3}中DA的信道和/或信号的功率情况,比如
Figure PCTCN2019099118-appb-000022
可以为如下之一:{PRB1,PRB2,PRB3}中的DA信道和/或信号的最小值,{PRB1,PRB2,PRB3}中的DA信道和/或信号的最大值,{PRB1,PRB2,PRB3}中的DA信道和/或信号的平均值,或者{PRB1,PRB2,PRB}中预定PRB中的DA信道或信号的功率,比如最低PRB ID中的DA的功率,比如PRB1中的DA信道或信号的功率,总之此时UB占有的多个PRB上,
Figure PCTCN2019099118-appb-000023
只有一个值。
本实施例的另一种实施方式中,公式(6-2)可以改为公式(6-3),即根据如下信息至少之一获取UB-PUSCH的发送功率根据公式(6-1)和(6-3)中的哪一个获取:IAB node2向IAB donor node/IAB node1发送的请求信息,IAB donor node向IAB node2发送的信令信息,UB和DA之间的复用方式信息,UB的信道或信号占有的PRB资源和DA的信道和/或信号占有的PRB资源之间是否有重叠。
Figure PCTCN2019099118-appb-000024
其中P DA,r表示UB-PUSCH所在的第r个PRB中的DA信道和/或信号的发送功率,当在此PRB中没有DA信道或信号时,P DA,r为0。,即此时UB占有的多 个PRB上,P DA,r为不同值。
也可以将UB-PUSCH占有的多个PRB(Physical resource block物理资源块)分为多个物理资源组,每个资源组中
Figure PCTCN2019099118-appb-000025
为一个值,不同物理资源组中,
Figure PCTCN2019099118-appb-000026
为不同值,即将公式(6-3)改为公式(6-4)所示:
Figure PCTCN2019099118-appb-000027
其中,P DA,g是UB-PUSCH的占有第g个物理资源块中,DA的信道或信号的平均功率,或者DA的信道或信号的最大功率,或者DA的信道或信号的最小功率。其中物理资源块的划分可以图1中的IAB donor/IAB node1通过信令信息通知给IAB node2,和/或IAB donor/IAB node1与IAB node2通过约定规则得到物理资源块的划分,比如UB-PUSCH的连续占有的频域资源块属于一个物理资源块组,非连续的频域资源块属于不同的物理资源块组。在一些实施例中,一个物理资源块组中包括一个或者多个物理资源块。
上述UB-PUSCH的功率获取方式,可以类似地用于UB-PUCCH,UB-SRS的功率获取中。
本实施例的另一种实施方式中,通信双方可以通过约定,确定通过上述公式之一确定UB-PUSCH的功率,比如IAB donor node/IAB node1和IAB node1约定采用公式(6-1)确定UB-PUSCH的功率。
本实施例的另一种实施例方式中,根据B个链路中的信道或信号的功率总和和预定值之间的关系,确定UB-PUSCH的功率确定方法,当UB和DA的发送功率总和小于或者等于预定值时,采用公式(1)确定UB-PUSCH的发送功率,当UB和DA的发送功率总和大于预定值时,采用公式(6-1)确定UB-PUSCH的发送功率,或者当UB和DA的发送功率总和大于预定值时,根据上述方式确定采用公式(6-1)和(6-4)其中之一确定UB-PUSCH的发送功率。
上述确定UB-PUSCH的功率方法,类似地可以用于确定UB-PUCCH,UB-SRS的功率。
应用实施例三
在本实施例中,图1中的IAB donor/IAB node1与IAB node2约定,第一 乘积与第二乘积的和不超过预定阀值,其中第一乘积为UB的发送功率与第一权值的乘积,第二乘积为DA的发送功率与第二权值的乘积,即需要满足如下公式:其中权值也可以称为功率缩放因子。

Figure PCTCN2019099118-appb-000034
当UB-PUSCH的功率和DA的功率总和大于预定值时,按照约定比例对UB和DA的功率进行缩减。公式(6-5)中w(1),w(2)可以为相同的值,也可以为不同的值。
在公式(6-5)中,当UB和DA的功率和大于预定值时,对于UB的所有信道或信号的功率缩减比例相同,DA的所有信道或信号的功率缩减比例相同,在本实施例中的另一种实施方式中,是当UB和DA的功率和大于预定值时,UB中的不同信道或信号的功率缩减比例不同,比如控制信道的缩减因子比较大,其中缩减因子越大,表示对于功率的削减越弱,比如当UB和DA的发送功率和大于约定值时,对于UB和DA的发送功率按照(6-7)所示的方式进行缩减:

应用实施例四
当DB和UA空分复用的时候,为了控制DB和UA之间的干扰,甚至当DB和UA频分复用的时候,如果DB和UA到达IABnode2的功率相差比较大时,使得DB的频域泄露对UA信道造成强干扰,从而需要控制DB和UA之间的功率,或者两者的接收功率的和不能超过预定值,否则会超过功控的线性区域,为此需要综合考虑DB和UA的功率。
方案1:IAB node2将UA信道和/或信号的功率信息反馈给IAB donor/IAB node1,其中UA信道和/或信号的功率信息包括如下信息至少之一:目标接收功率,最大发送功率,功率余量,计算路损的参考信号,路损调整因子,功率进程,功率调整量。IAB donor/IAB node1节点接收到UA的功率参数之后,就可以相应地调整DB信道或信号的发送功率,从而使得DB和UA之间的干扰最小化。示例性地上面的反馈信息对应的UA信道或信号是和DB信道或信号空分复用,和/或频分复用的,即UA和DB占有相同的时刻,或者占有相同的时刻中的相同的PRB,或者UA和DB占有的时域资源之间的交集非空。
在上面的反馈方案中,IAB node2在反馈UA的功率信息时,由于UA的不同用户,或者同一用户的不同UA发送波束不同,从而导致UA的功率信息可能不同,为此一种方式是反馈IABnode2下覆盖的所有用户的cell specific的UA功率信息,一种方式是不同的时域资源和/或不同频域资源上,反馈的UA的功率信息不同。
IAB node2可以反馈多套UA的功率信息,每一套功率信息对应UA的一个参考信号,或者每一套的功率信息对应一个DB的参考信号,表示和此DB的参 考信号所在的时域资源和/或频域资源上的UA的功率信息。
方案2:IAB node2反馈UA的功率信息(比如UA的目标接收功率)和DB的参考信号的RSRP之间的差值信息给IAB donor/IABnode1。这样IABdonor/IAB node1在接收到这个差值信息之后,就知道DB和UA到达IAB node2的功率差,从而可以据此调整DB的功率。不过由于UA对于不同的IAB node3/UE,和/或同一个IAB node3/UE的不同波束对应的目标功率会不同,DB的参考信号也有很多,为此一种方案是反馈UA的多个发送波束中的预定特征的发送波束的目标接收功率和DB的多个参考信号中的预定特征的参考信号的RSRP之间的差值。预定特征可以是多个值中的最大值,最小值,中间值等。另一种方案是反馈差值的时候对应一个(DB的参考信号索引,UA的发送波束索引)组合信息。第三种反馈方案是不同的时域资源和/或频域资源反馈一套差值信息,示例性地一个时域资源和/或频域资源对一个DA的参考信号集合,和/或对应一个UA的发送波束集合。本文中一个UA的发送波束可以通过UA的一个参考信号索引表示。
方案3:IABnode2请求DB的功率信息。其中DB的功率信息包括如下至少之一:IAB donor/IAB node1发送DB(即第一类信道或信号)的发送功率;DB到达IAB node2(即第一通信节点)的接收功率;DB到达IABnode2的接收功率和DB到达IABnode2的目标接收功率之间的差值;
方案4:IABnode2向IAB donor/IABnode1反馈UA的发送功率获取参数中的一种或者多种,其中UA的发送功率的获取参数可以包括以下一项或多项:UA占有的PRB个数,UA的子载波间隔,UA的子载波间隔和DB的子载波间隔的关系,UA占有的时域符号个数,UA占有的PRB集合和DB占有的PRB集合之间的交集包括的PRB个数,UA占有的时域符号集合和DB占有的时域符号集合之间的交集包括的时域符号个数。
应用实施例五
在上述实施例中,UB和DA的功率需要综合考虑,和/或DB和UA的功率需要综合考虑,特别是UB和DA共享IAB node2处的一套发送天线,UB和DA通过数字波束进行空分复用,类似地DB和UA也是通过数字波束进行空分复用接收。但是两者通过不同的panel进行空分复用,两个panel之间是独立的功放时,此时UB和DA的功率从功率受限的角度就不需要综合考虑,类似地DB和UA的功率从功率受限的角度在这种场景下也不需要综合考虑。
为此首先确定两个链路是否是独立的功放,根据是否是独立功放确定两个链路的功率是否需要综合考虑,其中是否有独立panel与如下信息至少之一之间有关联:UB与DA在第一通信节点处是否共享功率的信息;UB与DA的发送功率总和是否需要小于第一预定值,需要小于第一预定值,就表示共享功放或者功率总和需要受到限制;UB与DA的接收功率总和是否需要小于第二预定值;第一类信道或信号所在的成员载波与第二类信道或信号所在的CC是否属于一个频带,当属于一个Band,则他们一般是共享功放的,在不属于不同的Band的情况下就是独立功放的;UB所在的载频和预定值之间的关系,比如低频一般是共享功放的;DA所在的载频和预定值之间的关系;UB关联的所有准共参考信号中是否存在关联空间接收滤波参数的准共址参考信号,比如如果关联空间接收滤波参数表示是高频,或者是接收波束,一般是不共享功放的;DA关联的所有准共参考信号中是否存在关联空间接收滤波参数的准共址参考信号;UB是否配置空间发送滤波参数信息,比如配置空间发送滤波参数一般是独立功放的;DA是否配置空间发送滤波参数信息。
图1中的IAB node2也可以将上述反映UB和DA是否需要综合考虑功率的信息至少之一反馈给IAB donor/IAB node1。
应用实施例六
在本实施例中,一个上行信道或信号在一个时间单元中占有的多个时域符号中的功率不同。示例性的,一个上行信道和/或信号在一个slot中占有的多个时域符号中的功率可以不同。在本实施例中一个时间单元为一个slot,一个时间单元也可以为一次调度对应的一个上行信道或信号占有的多个slot。
在前述多个实施例中,基本认为UB的信道或信号和DA的信道和/或信号占有的时域资源重叠,或者UB的信道或信号占有的多个时域符号中的发送功率相同。在本实施例中,由于UB的信道或信号和DA的信道或信号可能只存在部分时域重叠,为了充分利用IAB节点的发送功率,需要考虑UB的信道或信号占有的多个时域符号中不同的时域符号组可以有不同的发送功率。
比如一个UB信道或信号占有的多个时域符号包括C个时域符号集合,C个时域符号集合中的每个时域符号集合关联一套功率信息,C为大于1的正整数。
如图9所示,UB-PUSCH占有的4个时域符号分为2个时域符号集合,如图9所示,UB-PUSCH占有的{n1,n2,n3,n4}4个时域符号分为2个时域符号 集合{n1,n2}和{n3,n4},在{n1,n2}时域符号上IABnode2需要发送UB和DA信号,在{n3,n4}时域符号上IAB node2只需要发送UB,不需要发送DA信道和/或信号。
为此可以有如下方案:
方案1:计算P CMAX_L,f,c的时候考虑DA的影响,将公式(4-1)更新为公式(7-1)P CMAX_L,f,c,tj=MIN{P EMAX,c–ΔTC,c,(P PowerClass–ΔP PowerClass)–MAX(MPR c+A-MPR c+ΔT IB,cTC, c+P DA,tj,P-MPR c)}   (7-1)

在本实施例中,一个参考信号资源指示信息关联多套功率信息,比如一个SRI(Sounding resource indication)关联多套功率信息,通过信令信息或者约定规则在多套功率信息中选择其中一套。

或者按照约定规则,在不同时间单元集合上SRI的功率信息为上述多套功率信息中的其中一套。比如在{slot2k+1,k=0,1,2...}上该SRI的功率为第一套功率信息,在{slot2k,k=0,1,2...}上该SRI的功率为第二套功率信息。
在一些实施例中,根据SRI对应的TA信息,确定SRI关联的功率信息,比如一个SRI关联2套功率信息,也关联2个TA值,当确定了该SRI的功率信息是根据2套功率信息中其中一个获取时,也可以得到发送该SRI对应的SRS是2个TA中的哪一个。其中TA是发送上行信号相对于下行定时的提前量。
在一些实施例中,根据调度SRI的DCI(Downlink control information下行控制信息)所在的CORESET(Control resource set控制资源集合,即控制信道资源)确定该SRI的功率信息是根据2套功率信息中哪一套获取,比如当DCI在CORESET1中时,该SRI的功率信息是根据第一套功率信息获取,比如当DCI在CORESET2中时,该SRI的功率信息是根据第二套功率信息获取。
类似地,根据调度SRI的DCI所在的CORESET确定该SRI的TA信息是根据2套TA信息中哪一套获取,比如当DCI在CORESET1中时,该SRI的TA信息是根据第一套TA信息获取,比如当DCI在CORESET2中时,该SRI的TA信息是根据第二套TA信息获取。
上述是根据CORESET确定一个SRI关联的功率/TA信息,也可以是CORESET所在的CORESET组和功率/TA信息之间建立关联,比如CORESET组1和第一套功率/TA有关联,CORESET组2和第二套功率/TA有关联,根据根据调度SRI的DCI所在的CORESET组确定功率/TA的选择信息。
上述一个参考信号资源指示信息关联多套功率信息的方法,类似地可以用于一个参考信号资源组合的指示信息关联多套功率信息,参考信号也可以是解调参考信号,或者上行随机接入序列信号。
