图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:智能手表、手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的传输处理方法进行详细地说明。
如图2所示,本申请实施例一种功率控制参数指示方法,包括:
步骤201,终端接收下行控制信息;
步骤202,所述终端根据所述下行控制信息进行功率控制;其中,
所述下行控制信息包括至少一个功率控制参数指示域,所述功率控制参数指示域指示不同物理上行共享信道PUSCH传输时机的第一功率控制参数,所述PUSCH传输时机与信道探测参考信号(Sounding Reference Signal,SRS)资源或SRS资源组关联。
这里,终端接收的下行控制信息(Downlink Control Information,DCI) 包括至少一个功率控制参数指示域,而该功率控制参数指示域指示不同PUSCH传输时机的第一功率控制参数,且PUSCH传输时机与SRS资源或SRS资源组关联。如此,结合TRP与SRS资源或SRS资源组的对应(即每个TRP具有对应的SRS资源或SRS资源组),在面对多个TRP时,通过包括至少一个功率控制参数指示域的DCI,就能够指示多个TRP的PUSCH传输时机的第一功率控制参数,来满足多个TRP传输要求。
其中,SRS资源组即多个(一组)SRS资源。可选地,功率控制参数指示域也可以理解为开环功率控制参数集指示(Open-loop power control parameter set indication)域。相应的,第一功率控制参数为用于确定发射功率的功率控制参数P0。下面实施例中,可采用P0直接替换第一功率控制参数,当然,第一功率控制参数的其它实现也可适用本申请的实施例,在此不再赘述。
可选地,所述不同PUSCH传输时机关联的SRS资源或SRS资源组不同。
应该知道的是,不同的SRS资源或SRS资源组是适用不同的TRP的,故,当不同PUSCH传输时机关联的SRS资源或SRS资源组不同,一个功率控制参数指示域能够指示针对不同TRP的PUSCH传输时机的第一功率控制参数。
如此,对于多个TRP,如TRP1、TRP2、TRP3和TRP4的PUSCH传输时机的P0的指示,由每个TRP的SRS资源或SRS资源组不同,在DCI中,可通过两个功率控制参数指示域来两两指示不同PUSCH传输时机的P0,如功率控制参数指示域1指示TRP1和TRP2的PUSCH传输时机的P0,功率控制参数指示域2指示TRP3和TRP4的PUSCH传输时机的P0。当然,也可以仅通过一个功率控制参数指示域来指示TRP1、TRP2、TRP3和TRP4的PUSCH传输时机的P0。
还应该知道的是,PUSCH传输时机可以是一个时隙(slot),一个名义(nominal)的重复传输时机,一个实际的重复传输时机或者连续的多个OFDM符号等。
可选地,该实施例中,所述下行控制信息还包括SRS资源指示(SRS resource indicator,SRI)域,所述SRI域指示SRS资源或SRS资源组关联的PUSCH传输时机的第一功率控制参数的候选参数集合。
即,DCI中还可包括SRI域,用于指示SRS资源或SRS资源组关联的PUSCH传输时机的第一功率控制参数的候选参数集合。
可选地,该实施例中,所述不同PUSCH传输时机中,至少一个PUSCH传输时机的第一功率控制参数的候选参数集合是预定义或预配置的。
也就是说,功率控制参数指示域指示的第一功率控制参数,至少一个第一功率控制参数属于预定义或预配置的候选参数集合。相应的,DCI中不包括任何SRI域,或者仅包括一个SRI域。
可选地,所述候选参数集合包括以下至少一项:
第一候选集合;
第二候选集合;
其中,所述第一候选集合属于第一集合列表;所述第二候选集合属于第二集合列表。
如此,第一功率控制参数的候选参数集合,可以为仅属于第一集合列表的集合,可以为仅属于第二集合列表的集合,还可以同时包括属于第一集合列表的集合和属于第二集合列表的集合。
需要说明的是,该实施例中,设置有第一集合列表和第二集合列表,以用于确定候选参数集合,从而得到第一功率控制参数。这里,第一集合列表和第二集合列表中的各集合均包括有第一功率控制参数。但是,第一集合列表区别于第二集合列表,第一集合列表的各集合中,除第一功率控制参数外,还包括有其它功率控制参数如alpha,路径损耗参考信号,闭环功率调整索引;而第二集合列表的各集合是专用于第一功率控制参数的集合,不包括其它功率控制参数。具体的,第一集合列表可为SRI映射PUSCH功率控制参数增加更新列表sri-PUSCH-MappingToAddModList或P0与alpha集合列表p0-AlphaSets;第二集合列表可为开环功率控制参数集合列表 p0-PUSCH-SetList-r16。
当然,第一集合列表和第二集合列表均可包括一个或多个列表。该实施例中,第一集合列表和第二集合列表是由高层信令配置或预定义的。
可选地,所述第一集合列表和第二集合列表分别与SRS资源集关联。
其中,第一集合列表和第二集合列表可关联相同的SRS资源集,也可关联不同的SRS资源集。
这里,SRS资源集是对应不同TRP的,如对应TRP1的SRS资源集1中的SRS资源或SRS资源组用于TRP1的传输,对应TRP2的SRS资源集2中的SRS资源或SRS资源组用于TRP2的传输。所以,第一集合列表可以是关联SRS资源集1的第一集合列表,第二集合列表可以是关联SRS资源集1的第二集合列表。当然,第一集合列表和第二集合列表可分别关联不同的SRS资源集,在此不再列举。
SRS资源集由无线资源控制(Radio Resource Control,RRC)配置,包含多个SRS资源。SRS资源组由SRI域指示,是SRS资源集中所有SRS资源的一个子集。
该实施例中,第一集合列表中的集合(即第一参数集合)可以为一个或多个,第二集合列表中的集合(即第二参数集合)可以为一个或多个。
故,上述SRI域指示的候选参数集合,通过排列顺序或索引值,在该候选参数集合为第一候选集合时,指示为第一集合列表中某个第一参数集合,如第一个或索引值为0的第一参数集合,或者索引值最小的第一参数集合;在该候选参数集合为第二候选集合时,指示为第二集合列表中某个第二参数集合,如第一个或索引值为0的第二参数集合,或者索引值最小的第二参数集合。
而预定义或预配置的候选参数集合,也可通过排列顺序或索引值,在该候选参数集合为第一候选集合时,预定义或预配置候选参数集合对应在第一集合列表中的排列顺序或索引值;在该候选参数集合为第二候选集合时,预定义或预配置候选参数集合对应在第二集合列表中的排列顺序或索引值。
需要说明的是,该实施例中,终端接收到DCI后,为确定PUSCH传输时机的P0,需先确定候选参数集合。
而对于高层信令配置或预定义了第一集合列表和第二集合列表的情况,该实施例中,可选地,确定的候选参数集合是包括第一候选集合和第二候选集合。例如,SRS资源或SRS资源组归属于SRS资源集1,则对于关联来自于SRS资源集1中的SRS资源或SRS资源组的PUSCH传输时机来说,第一候选集合可以由DCI中的关联SRS资源集1的SRI域在第一集合列表中指示,或者基于预定义或预配置在第一集合列表中选择;第二候选集合可以由DCI中的关联SRS资源集1的SRI域在第二集合列表中指示,或者基于预定义或预配置在第二集合列表中选择。之后,再进一步在第一候选集合和第二候选集合中确定目标参数集合来获取第一功率控制参数。若SRS资源或SRS资源组归属于SRS资源集2,对于关联SRS资源集2中的SRS资源或SRS资源组的PUSCH传输时机来说,同样可采用上述方式确定第一候选集合和第二候选集合。
当然,关联SRS资源集1中的SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数的第一候选集合为集合1,关联来自于SRS资源集2中的SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数的第一候选集合为集合2,集合1和集合2所属的第一集合列表可以是相同的,也可以是不同的。
关联不同SRS资源或SRS资源组的不同PUSCH传输时机,该不同PUSCH传输时机的P0的候选参数集合在相同的集合列表中可为不同集合。延续上例,假设对于关联来自于SRS资源集1中的SRS资源或SRS资源组的PUSCH传输时机来说,第一候选集合是第一集合列表中第一个集合,第二候选集合是第二集合列表中索引值最小的集合,则对于关联来自于SRS资源集2中的SRS资源或SRS资源组的PUSCH传输时机来说,第一候选集合可以由DCI中的关联SRS资源集2的SRI域在第一集合列表中指示,或者基于预定义或预配置在第一集合列表中选择,确定此时的第一候选集合是第 一集合列表中第二个集合;第二候选集合可以由DCI中的关联SRS资源集2的SRI域在第二集合列表中指示,或者基于预定义或预配置在第二集合列表中选择,确定此时第二候选集合是第二集合列表中索引值次小的集合。
当然,关联不同SRS资源或SRS资源组的不同PUSCH传输时机,该不同PUSCH传输时机的P0的候选参数集合在相同的集合列表中也可采用相同的集合,在此不再赘述。
可选地,所述功率控制参数指示域的比特大小为3比特。
此时,比特大小为3比特的功率控制参数指示域,将具体指示第一PUSCH传输时机的第一功率控制参数和第二PUSCH传输时机的第一功率控制参数。
当然,若功率控制参数指示域要指示关联两个以上不同SRS资源或资源组的PUSCH传输时机的第一功率控制参数,该功率控制参数指示域的比特数为M,其中M可以是不同的SRS资源或资源组的个数加1,或者是用于码本或非码本传输的SRS资源集的个数加1。
该实施例中,所述功率控制参数指示域的比特大小为3比特时,可选地,所述下行控制信息未包括SRI域的情况下,
所述功率控制参数指示域的第一比特指示第一目标参数集合为目标候选集合,所述目标候选集合属于第一目标集合列表,所述第一目标参数集合是所述不同PUSCH传输时机的第一功率控制参数的目标参数集合;
所述功率控制参数指示域的第二比特在所述第一比特指示的当前目标候选集合属于第二集合列表时,指示当前目标候选集合中,作为第一PUSCH传输时机的第一功率控制参数的功率控制参数,所述第一PUSCH传输时机关联的SRS资源或SRS资源组归属于第一SRS资源集;
所述功率控制参数指示域的第三比特在所述第一比特指示的当前目标候选集合属于第二集合列表时,指示当前目标候选集合中,作为第二PUSCH传输时机的第一功率控制参数的功率控制参数,所述第二PUSCH传输时机关联的SRS资源或SRS资源组归属于第二SRS资源集。
其中,所述第一PUSCH传输时机对应的目标候选集合归属的第一目标 集合列表,与所述第二PUSCH传输时机对应的目标候选集合归属的第一目标集合列表相同。
又或者,所述第一PUSCH传输时机对应的目标候选集合归属的第一目标集合列表,与所述第二PUSCH传输时机对应的目标候选集合归属的第一目标集合列表不同。
这里,第一目标集合列表可以是第一集合列表,也可以是第二集合列表。
DCI未包括SRI域也可以理解为:DCI中所有的SRI域都为0比特。因DCI未包括SRI域,第一PUSCH传输时机的第一功率控制参数和第二PUSCH传输时机的第一功率控制参数的候选参数集合都基于预定义或预配置确定。
而由于候选参数集合可包括第一候选集合和第二候选集合,如此,第一功率控制参数需要进一步在第一候选集合和第二候选集合中确定目标候选集合作为目标参数集合,从而在该目标参数集合中确定PUSCH传输时机的第一功率控制参数。
此时,3比特的功率控制参数指示域中,第一比特指示第一目标参数集合为目标候选集合,该目标候选集合归属于第一目标集合列表,由第一目标参数集合是不同PUSCH传输时机的第一功率控制参数的目标参数集合,即功率控制参数指示域所指示的第一PUSCH传输时机和第二PUSCH传输时机的第一功率控制参数,要么都是属于第一集合列表的集合,要么都是属于第二集合列表的集合。例如:“0”表示第一目标参数集合属于第一集合列表,“1”表示第一目标参数集合属于第二集合列表。
应该了解的是,不同PUSCH传输时机的第一功率控制参数的目标候选集合即使都属于第一集合列表,也可以是第一集合列表中的不同集合,同样,不同PUSCH传输时机的第一功率控制参数的目标参数集合即使都属于第二集合列表,也可以是第二集合列表中的不同集合。即,第一PUSCH传输时机对应的目标候选集合归属的列表1和第二PUSCH传输时机对应的目标候选集合归属的列表2可以是相同的集合列表,也可以是不同的集合列表。
第二比特是在第一比特指示的当前目标候选集合属于第二集合列表时, 指示第一PUSCH传输时机(关联第一SRS资源集中SRS资源或SRS资源组的PUSCH传输时机)的第一功率控制参数(第一目标P0)为其第二候选集合中的哪个。例如,“0”表示第一目标P0为集合中第一个P0,“1”表示第一目标P0为集合中第二个P0。此时第一PUSCH传输时机的第一功率控制参数的第一候选集合不用于确定第一目标P0。这里,当前目标候选集合是第一PUSCH传输时机的第一功率控制参数的目标候选集合。
第三比特是在第一比特指示的当前目标候选集合属于第二集合列表时,指示第二PUSCH传输时机(关联第二SRS资源集中SRS资源或SRS资源组的PUSCH传输时机)的第一功率控制参数(第二目标P0)为其第二候选集合中的哪个。例如,“0”表示第二目标P0为集合中第一个P0,“1”表示第二目标P0为集合中第二个P0。此时第二PUSCH传输时机的第一功率控制参数的第一候选集合不用于确定第二目标P0。这里,当前目标候选集合是第二PUSCH传输时机的第一功率控制参数的目标候选集合。
对于第一候选集合,考虑到第一集合列表中的各个集合可能仅包括一个P0,因此,在第一比特指示第一目标参数集合为第一候选集合的情况下,第二比特和第三比特无具体含义。当然,若第一集合列表中的各个集合包括多个P0,则第一PUSCH传输时机的第一功率控制参数和第二PUSCH传输时机的第一功率控制参数将基于预配置或预定义做进一步明确。
可选地,所述第一比特为所述功率控制参数指示域的最高有效位。
具体地,对于功率控制参数指示域3比特的具体取值不同,终端的理解如下表1、表2或表3所示,其中,目标第一参数集合是属于第一集合列表的集合,目标第二参数集合是属于第二集合列表的集合:
表1

表3
Figure PCTCN2022085108-appb-000004
Figure PCTCN2022085108-appb-000005
其中,在表3实现中,终端先解读功率控制参数指示域的第一比特,第一比特为1时再解读后两比特。
在上述表1-3中,目标第一参数集合和目标第二参数集合的确定可实现为:
示例一、网络侧设备配置一个第一集合列表p0-AlphaSets,对于关联第一SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第一参数集合对应p0-AlphaSets中第一个第一参数集合P0-PUSCH-AlphaSet,对于关联第二SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第一参数集合对应p0-AlphaSets中第二个第一参数集合P0-PUSCH-AlphaSet;此外,网络侧设备配置一个第二集合列表p0-PUSCH-SetList-r16,对于关联第一SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第二参数集合对应p0-PUSCH-SetList-r16中索引值(p0-PUSCH-SetId-r16)最小的P0-PUSCH-Set-r16,对于关联第二SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第二 参数集合p0-PUSCH-SetList-r16中p0-PUSCH-SetId-r16次小的P0-PUSCH-Set-r16。
示例二、网络侧设备配置两个第一集合列表sri-PUSCH-MappingToAddModList1,sri-PUSCH-MappingToAddModList2,分别关联第一、第二SRS资源集,对于关联第一SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第一参数集合对应sri-PUSCH-MappingToAddModList1中第一个第一参数集合SRI-PUSCH-PowerControl,或者,sri-PUSCH-PowerControlI=0的第一参数集合SRI-PUSCH-PowerControl,对于关联第二SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第一参数集合对应PUSCH-MappingToAddModList2中第一个第一参数集合SRI-PUSCH-PowerControl,或者,sri-PUSCH-PowerControlI=0的第一参数集合SRI-PUSCH-PowerControl,或者sri-PUSCH-PowerControlI=1的第一参数集合SRI-PUSCH-PowerControl;此外,网络侧设备配置两个第二集合列表p0-PUSCH-SetList-r16 1,p0-PUSCH-SetList-r16 2,分别关联第一、第二SRS资源集,对于关联第一SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第二参数集合对应p0-PUSCH-SetList-r16 1中p0-PUSCH-SetId-r16最小的P0-PUSCH-Set-r16,对于关联第二SRS资源集中的SRS资源或SRS资源组的PUSCH传输时机来说,目标第二参数集合对应p0-PUSCH-SetList-r16 2中p0-PUSCH-SetId-r16最小的P0-PUSCH-Set-r16。
此外,该实施例中,所述功率控制参数指示域的比特大小为3比特时,可选地,所述下行控制信息包括一个SRI域的情况下,
若所述SRI域关联第一SRS资源集,则所述功率控制参数指示域的第一比特指示关联第一SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数,第二比特和第三比特联合指示关联第二SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数;
若所述SRI域关联第二SRS资源集,则所述功率控制参数指示域的第一 比特和第二比特联合指示关联第一SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数,第三比特指示关联第二SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数;
其中,所述第一SRS资源或SRS资源组属于第一SRS资源集,所述第二SRS资源或SRS资源组属于第二SRS资源集。
由于第一PUSCH传输时机关联的SRS资源或SRS资源组归属于第一SRS资源集,则第一PUSCH传输时机关联的SRS资源或SRS资源组即第一SRS资源或SRS资源组;第二PUSCH传输时机关联的SRS资源或SRS资源组归属于第二SRS资源集,则第二PUSCH传输时机关联的SRS资源或SRS资源组即第二SRS资源或SRS资源组。
所以,对于DCI包括一个SRI域,且该SRI域关联第一SRS资源集的情况,则可知第一PUSCH传输时机的第一功率控制参数的候选参数集合。此时,功率控制参数指示域的第一比特指示关联第一SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数,即第一PUSCH传输时机的第一目标P0来源,例如:“0”表示第一目标P0来源于候选参数集合的第一候选集合,“1”表示第一目标P0来源于候选参数集合的第二候选集合。之后,第二比特和第三比特联合指示关联第二SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数,即第二PUSCH传输时机的第二目标P0来源,例如:“00”表示第二目标P0来源于候选参数集合的第一候选集合,“01”表示第二目标P0来源于候选参数集合的第二候选集合的第一个P0,“10”表示第二目标P0来源于候选参数集合的第二候选集合的第二个P0。
对于DCI包括一个SRI域,且该SRI域关联第二SRS资源集的情况,则可知第二PUSCH传输时机的第一功率控制参数的候选参数集合。此时,功率控制参数指示域的第一比特和第二比特联合指示关联第一SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数,即第一PUSCH传输时机的第一目标P0来源,例如:“00”表示第一目标P0来源于候选参数集合的第一候选集合,“01”表示第一目标P0来源于候选参数集合的第二候选集合的第 一个P0,“10”表示第一目标P0来源于候选参数集合的第二候选集合的第二个P0。之后,第三比特指示关联第二SRS资源或SRS资源组的PUSCH传输时机的第一功率控制参数,即第二PUSCH传输时机的第二目标P0来源,例如:“0”表示第二目标P0来源于候选参数集合的第一候选集合,“1”表示第二目标P0来源于候选参数集合的第二候选集合。
可选地,该实施例中,所述第一SRS资源集,以及所述第二SRS资源集是基于以下内容区分的:
SRS资源集索引大小;
SRS资源集配置顺序;
MAC CE指示;或者,
高层信令的配置信息。
例如,索引大的SRS资源集为第一SRS资源集,索引小的SRS资源集为第二SRS资源集;优先配置的SRS资源集为第一SRS资源集,在后配置的SRS资源集为第二SRS资源集。
另外,可选地,该实施例中,所述方法还包括:
所述终端确定PUSCH传输时机的第二功率控制参数。
这里,第二功率控制参数可为路损参考信号PL-RS。下面实施例中,可采用PL-RS直接替换第二功率控制参数,当然,第二功率控制参数的其它实现也可适用本申请的实施例,在此不再赘述。
可选地,所述确定PUSCH传输时机的第二功率控制参数,包括:
根据所述下行控制信息,以及关联的SRS资源或SRS资源组,确定PUSCH传输时机的第二功率控制参数;或者,
根据目标传输资源关联的至少一个第二功率控制参数,确定PUSCH传输时机的第二功率控制参数。
这里,目标传输资源可以是PUCCH资源或CORESET。终端确定PUSCH传输时机的第二功率控制参数,可由该目标传输资源关联的至少一个第二功率控制参数,如至少一个第二功率控制参数中的第一个第二功率控制参数。
终端也能够基于接收到的DCI以及PUSCH传输时机关联的SRS资源或SRS资源组,来确定该PUSCH传输时机的第二功率控制参数。
可选地,所述根据所述下行控制信息,以及关联的SRS资源或SRS资源组,确定PUSCH传输时机的第二功率控制参数,包括:
在所述下行控制信息未包括关联目标SRS资源集的SRI域的情况下,在第二目标参数集合中,确定关联目标SRS资源或资源组的PUSCH传输时机的第二功率控制参数。
可选地,所述第二目标参数集合为第一集合列表中的第一目标集合,所述目标SRS资源或资源组属于所述目标SRS资源集。
这里,终端能够在DCI不包括关联目标SRS资源集的SRI域的情况下,在第一集合列表中的第一目标集合(第二目标参数集合)中,确定关联目标SRS资源或资源组(属于该目标SRS资源集的SRS资源或资源组)的PUSCH传输时机的第二功率控制参数。
其中,第一目标集合可以基于预定义或预配置的索引确定,如第一集合列表中索引为0的集合;第一目标集合可以还可以基于预定义或预配置的排列顺序确定,如第一集合列表中第一个集合。可选地,该第一目标集合是关联该目标SRS资源集的第一集合列表。
例如,DCI中不包含关联第一SRS资源集的SRI域时,关联来自第一SRS资源集SRS资源或SRS资源组的PUSCH传输时机对应的目标PL-RS为第一集合列表中索引为0的集合中的PL-RS。DCI中不包含关联第二SRS资源集的SRI域时,关联来自第二SRS资源集SRS资源或SRS资源组的PUSCH传输时机对应的目标PL-RS为第一集合列表中索引为0或1的集合中的PL-RS。例如,第二目标参数集合为sri-PUSCH-power control,是由存在的SRI域或者预定义的集合索引ID=0得到的PL-RS集合;
假设网络侧设备配置了一个第一集合列表sri-PUSCH-MappingToAddModList,包含两个集合SRI-PUSCH-PowerControl,分别对应索引(sri-PUSCH-PowerControlId)为0和1;当调度PUSCH的DCI 不包含任何SRI域时,关联来自第一SRS资源集SRS资源或SRS资源组的PUSCH传输时机对应的路损参考信号,为sri-PUSCH-PowerControlId=0的SRI-PUSCH-PowerControl中关联的路损参考信号;关联来自第二SRS资源集SRS资源或资源组的PUSCH传输时机对应的路损参考信号,为sri-PUSCH-PowerControlId=1的SRI-PUSCH-PowerControl中关联的路损参考信号。
由于第一目标集合还可存在多个PL-RS,可以基于预定义或预配置确定第一目标集合中哪个PL-RS为目标PL-RS。
例如,当DCI中不包含关联第一SRS资源集的SRI域时,关联来自第一SRS资源集SRS资源或SRS资源组的PUSCH传输时机对应的目标PL-RS为第一目标集合中的第一个PL-RS。DCI中不包含关联第二SRS资源集的SRI域时,关联来自第二SRS资源集SRS资源或SRS资源组的PUSCH传输时机对应的目标PL-RS为第一目标集合中的第二个PL-RS。第一目标集合可为第一集合列表中索引为0或者最小索引对应的集合。
此外,可选地,该实施例中,所述方法还包括:
接收媒体接入控制单元媒体接入控制(Medium Access Control,MAC)控制单元(Control Element,CE);其中,MAC CE包括第一功率控制参数更新指示域,所述第一功率控制参数更新指示域指示至少一个集合索引和至少一个参数索引;
根据所述第一功率控制参数更新指示域,按照所述至少一个参数索引更新所述至少一个集合索引对应的集合。
这里,包括第二功率控制参数的集合中,通过该第二功率控制参数的索引指示具体的第二功率控制参数。如此,网络侧设备基于需求更新第二功率控制参数,发送包括第一功率控制参数更新指示域的MAC CE,终端接收该MAC CE后,在该MAC CE的至少一个集合索引对应的集合中,用该MAC CE的至少一个参数索引更新第二功率控制参数索引。
其中,所述至少一个集合索引是第一集合列表中集合的索引。此时,该 第一集合列表为sri-PUSCH-MappingToAddModList。所述至少一个参数索引用于表明在对应该至少一个集合索引的集合中,更新的PL-RS索引。
例如,MAC CE的格式如图9所示,第一功率控制参数更新指示域中,每个用于指示集合索引的域即SRI ID域,每个用于指示参数索引的域即PUSCH Pathloss Reference RS ID域。如此,假设包括第二功率控制参数的集合的索引取值范围为0~31,则MAC CE的第一功率控制参数更新指示域中,每个SRI ID域长度为5比特。
可选地,所述MAC CE还包括第二功率控制参数更新指示域,所述第二功率控制参数更新指示域指示对应所述至少一个集合索引的集合关联的SRS资源集,或者,对应所述至少一个集合索引的集合所属的集合列表。
这样,由该第二功率控制参数更新指示域,就能够明确该至少一个集合索引对应的集合关联的SRS资源集或所属的集合列表。例如,MAC CE的格式如图9所示,第二功率控制参数更新指示域即S域。
其中,该第二功率控制参数更新指示域可以是对MAC CE的保留域复用;也可以是增加一个新的域。
具体的,该第二功率控制参数更新指示域为“0”表示所述MAC CE中第一功率控制参数更新指示域指示的至少一个集合索引对应的集合都是关联第一SRS资源集;为“1”表示所述MAC CE中第一功率控制参数更新指示域指示的至少一个集合索引对应的集合都是关联第二SRS资源集。
或者,该第二功率控制参数更新指示域为“0”表示所述MAC CE中第一功率控制参数更新指示域指示的至少一个集合索引对应的集合属于第一集合列表,该第一集合列表为关联第一SRS资源集或者关联第一SRI域的第一集合列表;为“1”表示所述MAC CE中第一功率控制参数更新指示域指示的至少一个集合索引对应的集合属于第一集合列表,该第一集合列表为关联第二SRS资源集或者关联第二SRI域的第一集合列表。
又或者,该第二功率控制参数更新指示域为“0”表示所述MAC CE中第一功率控制参数更新指示域指示的至少一个集合索引对应的集合关联第一 集合列表,该第一集合列表为关联第一SRS资源集的第一集合列表;为“1”表示所述MAC CE中第一功率控制参数更新指示域指示的至少一个参数索引,是用于更新该至少一个集合索引的集合之后第N个集合中的对应参数索引。
可选地,所述第二功率控制参数更新指示域为预设数值的情况下,按照所述至少一个参数索引更新所述至少一个集合索引对应的集合之后第N个集合,N为目标偏移值。
预设数值如上述为1,假设N=2,第一功率控制参数更新指示域指示的集合索引是1,则在第二功率控制参数更新指示域为“1”时,在集合索引为3(1+2)的集合中,将PL-RS索引更新为第一功率控制参数更新指示域指示的PL-RS索引。
其中,所述目标偏移值为第二目标集合列表中全部的集合数量,所述第二目标集合列表为关联目标SRS资源集的第一集合列表。
目标SRS资源集为第一SRS资源集,则目标偏移值为关联第一SRS资源集的第一集合列表中全部的集合数量;目标SRS资源集为第二SRS资源集,则目标偏移值为关联第二SRS资源集的第一集合列表中全部的集合数量。
当然,目标偏移值可由高层信令配置;可由预定义确定,如N=16。
可选地,所述MAC CE还包括第三功率控制参数更新指示域,所述第三功率控制参数更新指示域指示所述至少一个集合索引对应的集合中,所述至少一个参数索引对应更新的参数标识。
也就是说,面对至少一个集合索引对应的集合包括多个参数索引的情况,可以由第三功率控制参数更新指示域指示的标识,明确具体的更新对象。
同样的,该第三功率控制参数更新指示域可以是对MAC CE的保留域复用;也可以是增加一个新的域。
具体地,该第三功率控制参数更新指示域为“0”表示所述MAC CE的参数索引对应更新集合索引指示的集合中,关联的第一个PL-RS索引;为“1”表示所述MAC CE中的参数索引对应更新集合索引指示的集合中,关联的第 二个PL-RS索引。
结合图9所示的MAC CE的格式,其中SRI ID共2L-5个:
示例一:S域为“0”表示SRI ID i域指示的SRI PUSCH power control属于第一集合列表sri-PUSCH-MappingToAddModList;为“1”表示SRI ID i域指示的SRI PUSCH power control属于另一第一集合列表sri-PUSCH-MappingToAddModList。
示例二:S域为“0”表示SRI ID i域指示的是关联第一SRS资源集的SRI PUSCH power control;为“1”表示SRI ID i域指示的是关联第二SRS资源集的SRI PUSCH power control。
示例三:S域为“0”表示SRI ID i域指示的是关联第一SRS资源集的SRI PUSCH power control;为“1”表示SRI ID i域指示的是关联第二SRS资源集的SRI PUSCH power control。
对于图9所示的MAC CE的格式中的其它域,R域为保留域,C域指示该MAC CE中最后一个字节是否存在两个SRI ID域,Serving CELL ID域为服务小区标识,带宽部分(Bandwidth Part,BWP)ID域为BWP标识。
