通常,DCI 2-3用于载波切换和/或SRS功率控制,本申请实施例通过重用DCI 2-3,用来激活至少一个终端的至少一个载波上的非周期SRS。例如,同时激活一个终端的多个载波上的非周期SRS;或同时激活多个终端的一个载波上的非周期SRS;或同时激活多个终端的多个载波上的非周期SRS。
该实施例中,终端接收的DCI用来激活至少一个终端的至少一个载波上的非周期SRS,以下将对上述“至少一个载波”和“至少一个终端”的实现方式进行举例说明。
在一个例子中,所述DCI包括类型A(type A),所述DCI包括至少一个传输块(block),所述DCI用于激活所述至少一个传输块中每个传输块对应的至少一个载波上的非周期SRS。
该例子中,每个传输块可以对应一个终端,DCI包括的至少一个传输块对应至少一个终端。可选地,DCI包括多个传输块,多个传输块和多个终端一一对应。
该例子中,每个传输块包括至少一个传输功率控制(Transmit Power Control,TPC)命令域,这至少一个TPC命令域通常是对应一个终端的至少一个载波。可选地,传输块包括的TPC命令域为多个,这多个TPC命令域 和同一个终端的多个载波一一对应。
在另一个例子中,所述DCI包括类型B(type B),所述DCI包括至少一个传输块,所述DCI用于激活所述至少一个传输块中每个传输块对应的一个载波上的非周期SRS。
该例子中,所述DCI包括至少一个传输块中,至少一个传输块对应一个终端,DCI包括的至少一个传输块对应至少一个终端。例如,DCI包括4个传输块,这4个传输块中的前2个传输块对应一个终端,后2个传输块对应另一个终端。
该例子中,每个传输块包括一个TPC命令域,这一个TPC命令域通常是对应终端的一个载波。
S204:发送所述非周期SRS。
可选地,该步骤可以在终端的激活带宽部分(BandWidth Part,BWP)上发送所述非周期SRS。该激活BWP可以是S202中的DCI指示的至少一个载波中任意一个载波内的BWP;还可以是终端当前使用的载波中的激活BWP。
本申请实施例提供的非周期SRS的传输方法,终端接收的DCI可以同时激活至少一个终端的至少一个载波上的非周期SRS,网络侧设备无需针对每个载波以及每个终端分别发送DCI,有利于减少DCI的开销,减少PDCCH拥堵,提高通信系统性能。
可选地,本申请各个实施例中提到的DCI用于非载波切换和/或载波切换的非周期SRS激活。例如,DCI用于非载波切换的非周期SRS激活;DCI用于载波切换的非周期SRS激活;DCI用于非载波切换以及载波切换的非周期SRS激活,具体例如,DCI中的一部分传输块用于非载波切换的非周期SRS激活,另一部分传输块用于载波切换的非周期SRS激活。
可选地,在同一个载波上配置的非周期SRS为同一种用途。对于非载波切换的载波上配置的非周期SRS,可以是配置任意一种用途(usage)的SRS。例如,在一个载波上只能配置一种用途的非周期SRS,该用途可以是天线切换等。
为了使终端确定出接收到的DCI是用于非载波切换和/或载波切换的非周期SRS激活,该实施例可以通过以下几种技术方案实现。
在第一个例子中,S202之前,终端还可以接收指示信息,该指示信息用于指示所述DCI用于非载波切换和/或载波切换的非周期SRS激活。
例如,所述DCI包括类型A,所述指示信息用于指示所述DCI对应第N个探测参考信号功率控制命令物理下行控制信道配置(SRS-TPC-PDCCH-Config),N是正整数;其中,在N≥2的情况下,所述DCI用于非载波切换的非周期SRS激活或用于非载波切换和载波切换的非周期SRS激活;在N=1或所述指示信息不存在的情况下,所述DCI用于载波切换的非周期SRS激活。
该实施例中,SRS-TPC-PDCCH-Config通常由网络侧设备通过无线资源控制(Radio Resource Control,RRC)配置,第1个SRS-TPC-PDCCH-Config用于确定终端进行载波切换使用的载波集合以及载波集合内的载波。本申请实施例可以将第1个SRS-TPC-PDCCH-Config之外的任意一个SRS-TPC-PDCCH-Config作为非载波切换使用的载波集合以及载波集合内的载波。
该实施例中,第1个SRS-TPC-PDCCH-Config之外的SRS-TPC-PDCCH-Config中配置的载波集合内的载波不是未配置PUSCH的小区载波。该例子中提到的第1个SRS-TPC-PDCCH-Config之外的SRS-TPC-PDCCH-Config,可以是第2个至第32个SRS-TPC-PDCCH-Config中的任意一个。
该实施例具体例如,终端不期望第1个SRS-TPC-PDCCH-Config之外的SRS-TPC-PDCCH-Config中配置的载波集合内的载波是未配置PUSCH的小区(PUSCH-less cell)载波。
在第二个例子中,S202中终端接收到的DCI满足如下1)至4)之一:
1)所述DCI包括第一指示域,所述第一指示域用于指示所述DCI用于非载波切换和/或载波切换的非周期SRS激活。例如,DCI 2-3中增加1比特 (bit),用于指示该DCI是否用于非载波切换的非周期SRS触发。具体例如,指示值为“0”表示DCI用于非载波切换的非周期SRS触发,指示值为“1”表示DCI用于载波切换的非周期SRS触发。又例如,DCI 2-3中增加指示比特,用于指示哪些传输块是用于非载波切换的非周期SRS触发,哪些传输块是用于载波切换的非周期SRS触发。再例如,DCI 2-3中增加1bit,指示值为“0”表示DCI用于非载波切换和载波切换的非周期SRS触发,指示值为“1”表示DCI用于载波切换的非周期SRS触发。再例如,DCI 2-3中增加2bit,指示值为“00”表示DCI用于载波切换的非周期SRS触发,指示值为“01”表示DCI用于非载波切换的非周期SRS触发,指示值为“10”表示DCI用于非载波切换和载波切换的非周期SRS触发。
需要说明的是,本申请各个实施例提到的载波切换和非载波切换共存的情况,可以是载波切换和非载波切换两者都配置,也可以其中一者未配置。
对于上述载波切换配置,或者是非载波切换配置,配置例如包括但不限于:1)DCI包括的传输块,如传输块编号1(block number1),传输块编号2,传输块编号3,...。2)比特起始位置,也相当于传输块起始位置是通过每个终端中高层参数startBitOfFormat2-3 or startBitOfFormat2-2SUL-v1530(TPC command per BWP)确定的,类型A中,每个传输块对应一个终端。
2)所述DCI的传输块中包括第二指示域,所述第二指示域用于指示所述传输块用于非载波切换或载波切换的非周期SRS激活。例如,DCI 2-3中每个传输块(block)内增加1bit,用于指示传输块是否用于非载波切换的非周期SRS触发。具体例如,指示值为“0”表示该传输块用于非载波切换的非周期SRS触发,指示值为“1”表示该传输块用于载波切换的非周期SRS触发。
3)无线资源控制(Radio Resource Control,RRC)配置中的SRS载波切换参数中包括第三指示域,所述第三指示域用于指示所述DCI用于非载波切换和/或载波切换的非周期SRS激活。例如,RRC中配置的SRS-carrierSwitching下增加1bit,用于指示DCI 2-3是否用于非载波切换的 非周期SRS触发。具体例如,指示值为“0”表示DCI用于非载波切换的非周期SRS触发,指示值为“1”表示DCI用于载波切换的非周期SRS触发。又例如,RRC中配置的SRS-carrierSwitching下增加指示比特,用于指示DCI2-3的哪些传输块是用于非载波切换的非周期SRS触发,哪些传输块是用于载波切换的非周期SRS触发。
4)媒体接入控制控制单元(Media Access Control-Control Element,MAC CE)中包括第四指示域,所述第四指示域用于指示或更新所述DCI用于非载波切换和/或载波切换的非周期SRS激活。例如,指示值为“0”表示DCI 2-3用于非载波切换的非周期SRS触发,指示值为“1”表示DCI 2-3用于载波切换的非周期SRS触发。又例如,MAC CE中增加指示比特,用于指示DCI 2-3的哪些传输块是用于非载波切换的非周期SRS触发,哪些传输块是用于载波切换的非周期SRS触发。
在第三个例子中,所述DCI通过目标无线网络临时标识(Radio Network Temporary Identity,RNTI)加扰;其中,所述目标RNTI指示所述DCI用于非载波切换和/或载波切换的非周期SRS激活。
例如,对DCI 2-3增加新定义的RNTI,该新定义的RNTI用于对DCI 2-3进行加扰,若终端使用所述新定义的RNTI检测出DCI 2-3,则表示该DCI2-3可用于非载波切换的非周期SRS激活,或用于非载波切换和载波切换的非周期SRS激活。又例如,若终端常规的RNTI检测出DCI 2-3,则表示该DCI2-3可用于载波切换的非周期SRS激活。
前文各个实施例主要介绍了如何使终端确定DCI是用于非载波切换和/或载波切换的非周期SRS激活。在DCI用于非载波切换的非周期SRS激活的情况下,终端可以不进行载波切换,在当前载波上发送非周期SRS,该非周期SRS可以是DCI指示的至少一个载波内的SRS。在DCI用于载波切换的非周期SRS激活的情况下,终端可以进行载波切换,发送切换到的载波上的非周期SRS。
以下将对非周期SRS激活的具体实现方式进行介绍。
在一个例子中,所述DCI包括类型B,所述DCI的传输块(可以是任意一个传输块)内的SRS请求(SRS request)域包括如下1)至4)至少之一:
1)第一码点,指示不激活非周期SRS资源集。
2)第二码点,指示激活所述传输块对应的小区上被配置的1或2个非周期SRS资源集。可选地,所述传输块对应的载波是载波切换的载波。
可选地,上述提到的非周期SRS资源集的用途(usage)可以为天线切换(antenna switching)。
3)第三码点,指示激活所述传输块对应的载波切换小区上的非周期SRS,或指示激活所述传输块对应的非载波切换小区上的非周期SRS,或指示不激活所述传输块对应的非载波切换小区上的非周期SRS。
4)第四码点,指示激活所述传输块对应的载波切换小区上的非周期SRS,或指示激活所述传输块对应的非载波切换小区上的非周期SRS。
为详细说明上述例子,以下将分四种情况进行说明。
情况1:SRS请求域占用1比特,包括第一码点和第二码点,分别对应不激活载波切换小区上的非周期SRS,以及激活载波切换小区上的非周期SRS。
情况2:SRS请求域占用2比特,包括第一码点,第二码点,第三码点和第四码点,分别对应不激活非载波切换小区上的SRS,激活载波切换小区上的非周期SRS,激活载波切换小区上的非周期SRS,激活载波切换小区上的非周期SRS。其中,指示激活载波切换小区上的非周期SRS的码点不用于指示触发状态。
情况3:SRS请求域占用2比特,包括第一码点,第二码点,第三码点和第四码点,分别对应不激活载波切换小区上的非周期SRS,激活载波切换小区上的非周期SRS,激活非载波切换小区上的非周期SRS,激活非载波切换小区上的非周期SRS。
其中,第三码点和第四码点指示的非周期SRS触发状态通常不一样,是通过其他方法对应的,或者只有第三码点,第三码点用于非载波切换小区上 的非周期SRS的激活。
情况4:SRS请求域占用2比特,包括第一码点,第二码点,第三码点和第四码点,分别对应不激活载波切换小区上的SRS,激活载波切换小区上的非周期SRS,不激活非载波切换小区上的非周期SRS,激活非载波切换小区上的非周期SRS。
在一个具体的例子中,SRS请求域可以包括第一码点,第二码点,同时还包括第三码点和第四码点的至少之一。具体例如,类型B的DCI的每个传输块内的SRS请求域的码点00指示不激活非周期SRS资源集;码点01/10/11中的任意一个码点(如01)指示激活该传输块对应的小区上被配置的1或2个非周期SRS资源集,这些非周期SRS资源集的用途可以为天线切换;剩余两个码点(如10/11)用于隐式指示所在传输块对应的载波是非载波切换的载波。
需要说明的是,上述提到的SRS请求域可以包括第一码点,第二码点,同时还包括第三码点和第四码点的至少之一,只是为了说明SRS请求域的可选值是上述多个中的一个。在实际应用中,终端接收到的DCI中的每个SRS请求域仅存在一个码点,例如,SRS请求域的码点为00,或01,或10,或11。
又例如,SRS请求域可以包括第一码点和第二码点,占用1比特。具体例如,类型B的DCI的每个传输块内的SRS请求域的码点00指示不激活非周期SRS资源集;码点01、10和11中的任意一个码点(如01)指示激活该传输块对应的小区上被配置的1或2个非周期SRS资源集,这些非周期SRS资源集的用途可以为天线切换。
可选地,所述第三码点关联第一触发状态(trigger state)的非周期SRS(资源集),所述第四码点关联第二触发状态的非周期SRS;其中,码点与触发状态的对应关系是预设的,或高层信令配置/更新的;或码点与触发状态的对应关系是按照码点的大小顺序确定的。
例如,第三码点和第四码点用于触发的非周期SRS资源集的触发状态沿 用预设码点和触发状态之间的关联关系。例如,第三码点和第四码点分别是10和11,10用于触发trigger state=2的非周期SRS资源集,11用于触发trigger state=3的非周期SRS资源集。
又例如,第三码点和第四码点码点按照码点大小顺序,依次用于触发trigger state=1和trigger state 2的非周期SRS资源集。具体例如,第三码点和第四码点分别是10和11,10用于触发trigger state=1的非周期SRS资源集,11用于触发trigger state=2的非周期SRS资源集。
在一个例子中,对于载波切换type B类型,本申请实施例可以重新定义SRS请求域码点与SRS资源集的触发状态的对应关系;其中,00(对应于前文的第一码点)指示不激活非周期SRS资源集;码点01/10/11中的任意一个码点(对应于前文的第二码点)指示激活该传输块对应的小区上被配置的1或2个非周期SRS资源集,这些非周期SRS资源集的用途可以为天线切换。可选的,所述2个非周期SRS资源集不限制配置的触发状态。
例如,第二码点01是用于激活的码点,当SRS请求域为01时,指示激活该传输块对应的小区上被配置的1或2个非周期SRS资源集,这些非周期SRS资源集的用途可以为天线切换。
可选地,所述2个非周期SRS资源集被配置的触发状态相同。
可选地,所述2个非周期SRS资源集被配置的触发状态与所述SRS请求域中激活的码点对应。例如,所述2个非周期SRS资源集配置的触发状态需要与激活的码点对应当SRS请求域为01时,指示激活对应服务小区上配置的非周期的用于天线切换的SRS资源集,且所述SRS资源集的触发状态配置为1。
可选的,所述2个非周期SRS资源集不限制配置的触发状态。例如,01是用于激活的码点,当SRS请求域为01时,指示激活对应服务小区上配置的非周期的用于天线切换的SRS资源集。
以下将结合类型A,对非周期SRS激活的具体实现方式进行介绍。
在一个例子中,所述DCI包括类型A,所述DCI的SRS请求域用于确 定目标触发状态的SRS资源集,实施例200提供的方法还包括:终端确定载波集合索引等于预设值的载波集合,该载波集合包括S202中提到的至少一个载波。该例子例如,终端确定SRS载波集合索引(SRS-cc-setIndex)标识(ID),即载波集合索引(cc-setIndex)等于4的载波集合,所述DCI的SRS请求域用于确定载波集合4中目标触发状态的SRS资源集。
该例子例如,终端已经确定出DCI是用于非载波切换的非周期SRS激活,终端直接确定载波集合索引等于4的载波集合,SRS请求域用于确定载波集合4中,与SRS请求域指示的触发状态相同的SRS资源集。
在一个例子中,所述DCI包括类型A,所述DCI的SRS请求域用于确定目标触发状态的SRS资源集,实施例200提供的方法还包括:确定所述SRS请求域的码点对应的载波集合,所述载波集合包括S202中提到的至少一个载波。SRS请求域的码点和载波集合的对应关系可以是协议约定的,或高层信令配置或更新的。
该例子例如,终端已经确定出DCI是用于非载波切换的非周期SRS激活,终端直接确定SRS请求域的码点对应的载波集合,SRS请求域还用于确定该载波集合中,与SRS请求域指示的触发状态相同的SRS资源集。
可选地,前文各个实施例中,索引为4的载波集合内的载波不是未配置PUSCH的小区载波,例如,终端不期望cc-setIndex4内的载波是PUSCH-less cell载波。
可选地,前文各个实施例中,所述DCI的SRS请求域的码点对应的载波集合内的载波不是未配置PUSCH的小区载波。例如,终端不期望SRS请求域的码点对应的cc-setIndex内的载波是PUSCH-less cell载波。
