具体实施方式
本发明实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G/B5G/6G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol, SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本申请实施例中并不限定。
本申请实施例涉及的网络设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本申请实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络设备(evolutional Node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB),也可以是家庭演进基站(Home evolved Node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本申请实施例中并不限定。在一些网络结构中,网络设备可以包括集中单元(centralized unit,CU)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。
网络设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO (Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO,也可以是分集传输或预编码传输或波束赋形传输等。
在使用多DCI框架独立调度PUSCH,或通过多个CG配置同时传输PUSCH,或同时通过DCI调度PUSCH和CG(Configured grant,配置授权)配置传输PUSCH时,若配置多个SRS resource set,终端设备无法确定DCI中或者CG配置中的SRI指示的SRI作用在哪个SRS resource set上,导致PUSCH的正确传输无法得到有效保证,传输性能下降。
例如,使用多DCI框架独立调度PUSCH时,终端设备确定的SRS resource set可能和网络侧理解的SRS resource set不一致,导致PUSCH的正确传输无法得到有效保证。又例如,当终端设备通过多个CG配置同时传输PUSCH时,如果确定所有CG配置均与第一个SRS resource set关联,由于每个SRS resource set通常与一个panel(天线面板)关联,则可能导致终端设备只能使用单个panel进行PUSCH同时传输,导致PUSCH传输性能下降。
有鉴于此,本申请实施例中提出了一种PUSCH的传输方法、设备及存储介质。
在本申请实施例中,终端设备可以根据预定义的规则理解用于传输PUSCH的SRS resource set,也即确定SRS resource set作用在哪个PUSCH上。这样,当通过多DCI框架独立调度PUSCH时,能够保证网络设备确定的SRS resource set和终端设备确定的SRS resource set一致,能够保证PUSCH的正确传输;当同时通过DCI调度PUSCH和CG配置传输PUSCH,或者通过多个CG配置传输PUSCH时,可以确定不同的SRS resource set,保证多个panel同时进行传输,提高PUSCH传输性能。
在另一种情况下,可以由网络设备指示给终端设备采用哪个SRS resource set。这种指示的方式可以是显示的也可以是隐式的,由此也能够保证PUSCH的正确传输,提高PUSCH传输性能。
下面通过具体的实施方式对本申请实施例提供的PUSCH的传输方法进行说明。为便于理解,下面分别对基于预定义的规则确定SRS resource set和/或基于指示确定SRS resource set的方式进行说明。
一、基于预定义的规则确定SRS resource set
如图1所示,为终端设备基于预定义的规则确定SRS resource set的方法流程图,该方法应用于至少一个DCI调度PUSCH的场景,包括以下步骤:
步骤101,在终端设备在DCI中检测到SRI的情况下,基于预定义的规则,确定指定参数和SRS资源集之间的关联关系;并在步骤102中,基于所述关联关系,确定SRS资源集。
其中,该预定义的规则用于确定指定参数与SRS资源集之间的关联关系;所述指定参数包括以下至少一种:高层参数CORESETPoolIndex、检测到的用于传输所述DCI或PDCCH(Physical Downlink Control Channel,物理下行控制信道)的控制资源集CORESET、传输配置指示TCI状态配置、所述DCI中的指定信息域、所述终端设备的能力值索引。
上述终端设备的能力值索引为终端设备的panel(天线面板)相关的能力值,该能力值用于指示最大的SRS天线端口数。例如,在Rel-17上行panel选择场景中,在传输开始前,终端设备可以上报panel相关的能力值集合索引:capability[set]index,所述能力值集合索引也可以简称为能力值索引。每个能力值索引包括最大支持的SRS端口数(也可以被称为能力值),任意两个能力值索引对应的SRS端口数是不相同的。
网络侧设备可以根据终端上报的能力值索引确定终端具有几个SRS端口的panel。例如,一个终端设备具有三个panel,分别具有2,2,4个SRS天线端口数,则终端设备可以上报2个能力值索引,分别对应2个SRS端口和4个SRS端口,网络侧在接收到终端设备上报的能力值索引后,可以确定所述终端设备至少具有2端口和4端口的panel。在Rel-17中,终端上报的能力值索引仅可以用于波束测量上报,在进行L1-RSRP(Layer 1 Reference Signal Received Power,层1参考信号接收功率)或L1-SINR(Layer 1 Signal to  Interference and Noise Ratio,层1信干噪比)上报时,终端设备在上报每个CRI/SSBRI(Channel state information-reference signal Resource Indicator/Synchronization Signal Block Resource Indicator,信道状态信息参考信号资源指示/同步信号块资源指示)以及相应的L1-RSRP或L1-SINR时,会携带一个能力值索引,表示本次测量值是由哪个panel进行测量的。
下面给出例1)至例5),对终端设备如何基于预定义的规则及指定参数和SRS资源集之间的关联关系确定SRS资源集进行说明。
例1)、指定参数中包括CORESET时,基于关联关系确定SRS资源集:
指定参数中的CORESET和SRS resource set具有默认的关联关系。
在基于关联关系确定SRS资源集时,可实施为:检测用于传输所述DCI或PDCCH的CORESET;然后,从至少一个SRS资源集中选出与所述CORESET关联的SRS资源集作为用于传输所述PUSCH的SRS资源集。
也即,CORESET和SRS资源集之间具有默认的关联关系,实施时,先确定用于传输所述DCI或PDCCH的CORESET,然后基于该关联关系确定出该CORESET的SRS资源集。
例2)、指定参数中包括CORESET和CORESETPoolIndex时,基于关联关系确定SRS资源集:
此种情况下可实施为:检测用于传输所述DCI或PDCCH的CORESET;然后从至少一个SRS资源集中选出与所述CORESET或CORESET的CORESETPoolIndex关联的SRS资源集作为用于传输所述PUSCH的SRS资源集。
例如,可以先确定出用于传输所述DCI或PDCCH的CORESET1,然后确定CORESET1的CORESETPoolIndex1,然后选择CORESETPoolIndex1关联的SRS资源集供后续PUSCH的传输。
例3)、基于CORESET或CORESETPoolIndex的关联关系确定SRS资源:
无论预定义的规则是上述例1)情况还是例2)中的情况,预定义的规则 中指定参数和SRS资源集的关联关系都可以基于配置的SRS资源集或基于所述终端设备上报的能力值索引确定。
例如、若所述指定参数包括CORESET,所述关联关系包括CORESET与SRS资源集之间的关联关系,则基于配置的SRS资源集确定所述关联关系可实施为:
a、基于配置的SRS资源集确定所述关联关系
a-1,当网络设备配置一定数量的SRS资源集时,所述关联关系可以是以下关联关系a-1-1至关联关系a-1-3中至少一种关联关系:
关联关系a-1-1:第一指定CORESET,或所有CORESET与一个SRS资源集关联;该第一指定CORESET可以为CORESETPoolIndex取值为0的CORESET,或未配置CORESETPoolIndex的CORESET,也可以为CORESETPoolIndex取值为1的CORESET。当CORESET未配置CORESETPoolIndex时,默认或等同该CORESET的CORESETPoolIndex取值为0。
关联关系a-1-2:第二指定CORESET与网络设备配置的两个SRS资源集中的一个SRS资源集关联,第三指定CORESET与另一个SRS资源集关联;例如,第二指定CORESET可以是未配置CORESETPoolIndex的CORESET或CORESETPoolIndex取值为0的CORESET,第三指定CORESET可以是CORESETPoolIndex取值为1的CORESET,第二指定CORESET和第三指定CORESET反过来也是可以的。
关联关系a-1-3:第二指定CORESET对应网络设备配置的多个SRS资源集中的第一资源集集合,第三指定CORESET对应所述多个资源集中的第二资源集集合。
例如,第二指定CORESET与第一个SRS资源集和第二个SRS资源集关联,第三指定CORESET与第三个SRS资源集和第四个SRS资源集关联。或者,第二指定CORESET与第一个SRS资源集和第三个SRS资源集关联,第三指定CORESET与第二个SRS资源集和第四个SRS资源集关联。或者,第 二指定CORESET与第一个SRS资源集到第N个SRS资源集关联,第三指定CORESET与第N+1个SRS资源集到第2N或M个SRS资源集关联。或者,第二指定CORESET与第一个SRS资源集,第三个SRS资源集,…,到第2N-1或第2N+1个SRS资源集关联,第三指定CORESET与第2个SRS资源集,第4个SRS资源集,…,第2N个SRS资源集关联。
a-2,当网络侧配置的SRS资源集的数量可变时,还可以根据配置的SRS资源集的数量,确定所述关联关系:
a-2-1,配置了一个SRS资源集:
在所述网络设备为所述终端设备配置一个SRS资源集的情况下,所述一个SRS资源集与第一指定CORESET关联,或所述一个SRS资源集与所有CORESET关联。
a-2-2,配置了两个SRS资源集:
在所述网络设备为所述终端设备配置两个SRS资源集的情况下,未配置CORESETPoolIndex的CORESET或CORESETPoolIndex取值为0的CORESET对应所述两个SRS资源集中的一个SRS资源集,CORESETPoolIndex取值为1的CORESET对应另一个SRS资源集。
例如,两个SRS资源集分别为SRS资源集1和SRS资源集2,则SRS资源集1和CORESETPoolIndex取值为0的CORESET关联,SRS资源集2和CORESETPoolIndex取值为1的CORESET关联。
a-2-3,配置多个SRS资源集
在所述网络设备为所述终端设备配置四个SRS资源集的情况下,未配置CORESETPoolIndex的CORESET或CORESETPoolIndex取值为0的CORESET对应第一个SRS资源集和第二个SRS资源集,CORESETPoolIndex取值为1的CORESET对应第三个SRS资源集和第四个SRS资源集。
综上所述,当配置一个SRS resource set时,该预定义的规则规定这一个SRS resource set和所有CORESET关联,或者和部分CORESET关联,或者和未配置CORESETPoolIndex的CORESET关联,或者和CORESETPoolIndex 取值为0的CORESET关联,或者和CORESETPoolIndex取值为1的CORESET关联。
当配置两个SRS resource set时,可默认每个SRS resource set和一个或多个CORESET或CORESETPoolIndex关联。
当配置三个及以上SRS resource set时,可以默认其中部分SRS resource set和一个或多个CORESET或CORESETPoolIndex关联,以此类推。
示例性的,对于如何根据SRS resource set的数量建立预定义的规则,会作如下假设:如果参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2对于'codebook'or'noncodebook'usage配置2个SRS resource set,则第1个SRS resource set与CORESETPoolindex取值为0的CORESET关联,第2个SRS resource set与CORESETPoolindex取值为1的CORESET关联。
在另一种情况下,该实施方式中如果参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2对于'codebook'or'noncodebook'usage配置1个SRS resource set,则该SRS resource set与CORESETPoolindex取值为0的CORESET关联。
在另一种情况下,该实施方式中如果参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2对于'codebook'or'noncodebook'usage配置3个或4个SRS resource set,则第1个和/或第3个SRS resource set与CORESETPoolindex取值为0的CORESET关联,第2个和/或第4个SRS resource set与CORESETPoolindex取值为1的CORESET关联。
在以上关联关系中,CORESETPoolindex取值为0的CORESET和CORESETPoolindex取值为1的CORESET也可以进行互换。
在本申请的所有实施例中,CORESETPoolindex取值为0的CORESET既包含配置CORESETPoolindex,且该参数取值为0的CORESET,也包含未配置CORESETPoolindex参数的CORESET。
以上所述第n(n=1,2,3,4,…)个SRS resource set均是按照参数 srs-ResourceSetId从低到高或从高到低排序确定的,例如高层参数‘txconfig’被配置为‘codebook’时,第一个SRS resource set是usage为‘codebook’的SRS resource set中具有最低srs-ResourceSetId取值的SRS resource set。当高层参数‘txconfig’被配置为‘noncodebook’时,第一个SRS resource set是usage为‘noncodebook’的SRS resource set中具有最低srs-ResourceSetId取值的SRS resource set。
当UE在某个CORESET检测到具有SRI域的DCI后,可以根据以上预定义规则确定CORESET关联的SRS resource set,进而根据SRI的指示确定相应的SRS资源以及PUSCH的传输端口。例如,在确定用于传输PUSCH的SRS resource set时,可以先检测用于传输DCI的CORESET,然后若预定义的规则是CORESET和SRS resource set之间的关联关系,则基于该关联关系可确定用于传输PUSCH的SRS resource set。此外,若预定义的规则是CORESETPoolIndex与SRS resource set之间的关联关系,则基于检测到DCI的CORESET获取为CORESET配置的CORESETPoolIndex,然后基于关联关系即可确定用于传输PUSCH的SRS resource set。此外,若CORESET未配置CORESETPoolIndex时,可以根据该CORESET默认的CORESETPoolIndex取值(即数值0)确定SRS resource set。
b,还可以直接建立参数CORESETPoolIndex和SRS资源集的关联。
例如:
b-1,在网络设备配置一定数量的SRS资源集的情况下,所述关联关系可以是以下关联关系b-1-1至关联关系b-1-3中至少一种关联关系:
关联关系b-1-1:第一指定CORESETPoolIndex取值,或所有CORESETPoolIndex取值与一个SRS资源集关联;该第一指定CORESETPoolIndex取值可以为0或1。
关联关系b-1-2:第二指定CORESETPoolIndex取值与一个SRS资源集关联,第三指定CORESETPoolIndex取值与一个SRS资源集关联;例如,第二指定CORESETPoolIndex取值可以是0或1,第三指定CORESETPoolIndex 取值可以是1或0。
关联关系b-1-3:第二指定CORESETPoolIndex取值与第一个SRS资源集和第二个SRS资源集关联,第三指定CORESETPoolIndex取值与第三个SRS资源集和第四个SRS资源集关联。或者,第二指定CORESETPoolIndex取值与第一个SRS资源集和第三个SRS资源集关联,第三指定CORESETPoolIndex取值与第二个SRS资源集和第四个SRS资源集关联。或者,第二指定CORESETPoolIndex取值与第一个SRS资源集到第N个SRS资源集关联,第三指定CORESETPoolIndex取值与第N+1个SRS资源集到第2N或M个SRS资源集关联。或者,第二指定CORESETPoolIndex取值与第一个SRS资源集,第三个SRS资源集,…,到第2N-1或第2N+1个SRS资源集关联,第三指定CORESETPoolIndex取值与第2个SRS资源集,第4个SRS资源集,…,第2N个SRS资源集关联。
b-2,当网络侧配置的SRS资源集的数量可变时,还可以根据配置的SRS资源集的数量,确定所述关联关系,包括以下情况:
b-2-1,配置了一个SRS资源集:
在所述网络设备为所述终端设备配置一个SRS资源集的情况下,所述一个SRS资源集与第一指定CORESETPoolIndex取值关联,或所述一个SRS资源集与所有CORESETPoolIndex取值关联。
b-2-2,配置了两个SRS资源集:
在所述网络设备为所述终端设备配置两个SRS资源集的情况下,第二指定CORESETPoolIndex取值对应所述两个SRS资源集中的一个SRS资源集,第三指定CORESETPoolIndex取值对应另一个SRS资源集。
b-2-3,配置四个SRS资源集:
在所述网络设备为所述终端设备配置四个SRS资源集的情况下,第二指定CORESETPoolIndex取值对应第一个SRS资源集和第二个SRS资源集,第三指定CORESETPoolIndex取值对应第三个SRS资源集和第四个SRS资源集。
在建立参数CORESETPoolIndex和SRS资源集的关联关系的情况下,终 端可以根据检测到DCI所在的CORESET的CORESETPoolIndex取值确定所述DCI作用的SRS资源集,进而确定相应的SRS资源用于PUSCH传输。
c、基于能力值确定关联关系:所述关联关系包括CORESET与能力值索引之间的第一关系,并包括能力值索引与SRS资源集之间的第二关系。
c-1,终端设备上报一个能力值索引的情况
在所述终端设备上报一个能力值索引的情况下,则所述一个能力值索引与第二指定CORESET或所有CORESET建立所述第一关系,且所述一个能力值索引与指定SRS资源集建立所述第二关系。
当上报一个能力值索引时,默认该能力值索引与CORESETPoolindex取值为0的CORESET具有第一关系,或者默认该一个能力值索引与所有CORESET;具有第一关系,然后该一个能力值索引和指定SRS资源集具有第二关系。
由此,确定SRS资源集时,先确定检测到DCI或PDCCH的CORESET,然后基于第一关系确定该CORESET对应的能力值,然后基于第二关系确定该能力值对应的SRS资源集。
c-2,终端设备上报多个能力值索引的情况
在所述终端设备上报多个能力值索引的情况下,则所述多个能力值中的部分能力值索引与未配置CORESETPoolIndex的CORESET或CORESETPoolIndex取值为第一值的CORESET建立所述第一关系,剩余另一部分能力值索引与CORESETPoolIndex取值为第二值的CORESET建立所述第一关系,且每个能力值与每个能力值指定的SRS资源集建立所述第二关系。
例如,在所述终端设备上报多个能力值索引的情况下,则所述多个能力值中的部分能力值索引与未配置CORESETPoolIndex的CORESET或CORESETPoolIndex取值为0的CORESET具有第一关系,剩余另一部分能力值索引与CORESETPoolIndex取值为1的CORESET具有第一关系,且每个能力值与每个能力值指定的SRS资源集具有第二关系。也即,第一值和第二值可以根据需求设定,第一值可以为0也可以为1,第二值可以1也可以为0, 只要第一值和第二值区分出不同CORESETPoolIndex即可。
再例如,当上报两个能力值时,默认第一个能力值与CORESETPoolindex取值为0的CORESET或未配置参数CORESETPoolindex的CORESET关联,第二个能力值与CORESETPoolindex取值为1的CORESET关联;或者,默认第一个能力值与CORESETPoolindex取值为1的CORESET关联,第二个能力值与CORESETPoolindex取值为0的CORESET或未配置参数CORESETPoolindex的CORESET关联;
当上报三个或以上能力值时,默认第2n-1(n=1,2,…)个能力值或2n+1(n=0,1,2,…)个能力值与CORESETPoolindex取值为0的CORESET或未配置参数CORESETPoolindex的CORESET关联,第2n(n=0,1,2,…或n=1,2,…)个能力值与CORESETPoolindex取值为1的CORESET关联;或者默认第2n(n=0,1,2,…或n=1,2,…)个能力值与CORESETPoolindex取值为0的CORESET或未配置参数CORESETPoolindex的CORESET关联,第2n-1(n=1,2,…)个能力值或2n+1(n=0,1,2,…)个能力值与CORESETPoolindex取值为1的CORESET关联。
d、还可以建立参数CORESETPoolIndex和能力值的关联,进而建立参数CORESETPoolIndex和SRS资源集的关联。例如:
d-1,终端设备上报一个能力值索引的情况
在所述终端设备上报一个能力值索引的情况下,则所述一个能力值索引与第二指定CORESETPoolIndex取值或所有CORESETPoolIndex取值建立所述第一关系,且所述一个能力值索引与指定SRS资源集建立所述第二关系。所述第二指定CORESETPoolIndex取值可以是0或1。
d-2,终端设备上报多个能力值索引的情况
在所述终端设备上报多个能力值索引的情况下,则所述多个能力值中的部分能力值索引与第三指定CORESETPoolIndex取值建立所述第一关系,剩余另一部分能力值索引与第四指定CORESETPoolIndex取值建立所述第一关系。所述第三指定CORESETPoolIndex取值可以是0或1,所述第四指定 CORESETPoolIndex取值可以是1或0。
由此,确定SRS资源集时,先确定检测到DCI或PDCCH的CORESET的CORESETPoolIndex取值,然后基于CORESETPoolIndex取值确定对应的能力值,进而基于能力值和SRS资源集的关联关系确定对应的SRS资源集。
下面再举个例子对如何基于能力值确定的关联关系,来确定SRS资源集进行进一步说明:
例如,当UE上报一个能力值时,所述能力值与CORESETPoolindex取值为0的CORESET关联;
当UE上报2个能力值时,第一个能力值与CORESETPoolindex取值为0的CORESET关联,第二个能力值与CORESETPoolindex取值为1的CORESET关联;
当UE上报3个或以上能力值时,第2n-1(n=1,2,…)个能力值或2n+1(n=0,1,2,…)个能力值与CORESETPoolindex取值为0的CORESET关联,第2n(n=0,1,2,…或n=1,2,…)个能力值与CORESETPoolindex取值为1的CORESET关联。
在以上关联关系中,CORESETPoolindex取值为0的CORESET和CORESETPoolindex取值为1的CORESET也可以进行互换。
当UE在某个CORESET检测到具有SRI域的DCI后,可以根据以上预定义规则确定CORESET关联的能力值,进而确定能力值对应的最大SRS端口以及SRS resource set,并根据SRI的指示确定相应的SRS资源以及PUSCH的传输端口。
当然需要说明的是,上述关联关系仅是举例说明,并不用于限定本申请实施例。
例4)、基于指定参数中的TCI状态配置及预定义的规则确定SRS资源:
可预先定义不同TCI状态配置关联不同的SRS resource set。
由此,在确定用于传输PUSCH的SRS resource set时,可以先确定与DCI关联的TCI状态配置,然后根据该预定义的规则,可确定采用哪个SRS resource  set以确定SRS资源。
例如,所述TCI状态配置可以是DCI中的TCI域中的状态位。例如,一个TCI域指示N个TCI状态。所述预定义规则可以是每个TCI状态位对应一个SRS资源集。例如,TCI域指示4个TCI状态,其中第一个TCI状态位和第二个TCI状态位用于下行TCI状态指示,第三个TCI状态位和第四个TCI状态位用于上行TCI状态指示。根据预定义规则,终端可以确定第三个TCI状态位与第一个SRS资源集关联,第四个TCI状态位与第二个SRS资源集关联。当TCI状态位指示为第一特定值(如‘111’)或预留值(‘Reserved’)时,则表示不使用该TCI状态位。当TCI状态位指示为第二特定值(如‘000’到‘110’)时,则表示该TCI状态位指示了一个具体的TCI状态。因此终端可以根据DCI中的TCI的指示,以及TCI状态位与SRS资源集的关联,确定所述DCI作用的SRS资源集,进而确定相应的SRS资源用于PUSCH传输。
又例如,仍然通过预定义的规则确定一个或多个TCI状态位分别对应一个SRS资源集。在TCI域指示TCI状态时,使用SRS resource set域或者另一个信息域指示哪个信息位生效,例如第一个TCI状态位生效,或第二个TCI状态位生效,或者2个TCI状态位都生效。假如使用SRS resource set时,例如,SRS resource set指示‘0’时,表示第一个TCI状态生效,指示‘1’时表示第二个TCI状态生效,指示‘2’或’3’时表示2个TCI都生效。因此终端可以根据DCI的指示,以及所述预定义的规则,确定当前DCI中的SRI域作用的SRS资源集,进而确定相应的SRS资源用于PUSCH传输。
例5)、基于指定参数中的能力值索引确定SRS资源集:
可预先定义不同能力值索引关联不同的SRS resource set。
这样,在确定用于传输PUSCH的SRS resource set时,可以先确定终端设备上报的能力值,然后根据该预定义的规则,可确定采用哪个SRS resource set确定SRS资源。
例如,第一个能力值索引和SRS resource set 0关联,第二个能力值索引和SRS resource set 1关联。当然,这里的关联关系仅是举例说明,并不用于 限定本申请实施例。所述第一个能力值索引和第二个能力值索引分别按照SRS端口的取值从小到大排序,或从大到小排序。例如终端上报的能力值索引对应的SRS端口数分别是2和4,则第一能力值索引指的是SRS端口数为2的能力值索引,第二能力值索引指的是SRS端口数为4的能力值索引。
又例如,终端针对每个TRP(Transmission and Receiving Point,发送接收节点)的调度分别上报能力值索引(例如对应CORESETPoolIndex取值为0或1),进而网络设备和终端均可以确定所述TRP的调度对应的SRS资源集。
步骤103,基于所述SRS资源集确定SRS资源。
实施时,基于DCI中的SRI域确定SRS资源。
步骤104,基于所述SRS资源发送PUSCH。
综上所述,基于预定义的规则的实现方式可有多种,实施时可根据实际需求确定采用的预定义的规则。终端设备采用预定义的规则确定SRS资源集时有章可循,可保证终端设备确定的SRS资源集能够保证PUSCH的准确传输。
如图2所示,为终端设备基于预定义的规则确定SRS resource set的方法流程图,该方法应用于通过至少一个CG配置传输PUSCH的场景,包括以下步骤201-204:
步骤201,在终端设备获取到CG配置中包含的SRI的情况下,基于预定义的规则,确定指定参数和SRS资源集之间的关联关系;并在步骤202中,基于所述关联关系,确定SRS资源集。
其中,该预定义的规则用于确定指定参数与SRS资源集之间的关联关系;所述指定参数包括以下至少一种:高层参数CORESETPoolIndex、传输配置指示TCI状态配置、所述终端设备的能力值索引、SRS资源集索引、CG索引、指定无线资源控制RRC参数。
上述指定参数可以通过RRC参数进行配置,例如RRC参数可以配置在rrc-ConfiguredUplinkGrant下,或者是srs-ResourceIndicator或srs-ResourceIndicator2-r17下。CG配置包含的SRI指示可以由 srs-ResourceIndicator或srs-ResourceIndicator2-r17配置,指示的是与其关联的SRS resource set中的SRS资源。CG索引可以是CG配置ID,例如configuredGrantConfigIndex-r16(最多32个)。
在一些实施方式中,指定参数包括高层参数CORESETPoolIndex时,基于所述关联关系确定SRS资源集,可实施为:
获取所述CG配置或者所述SRI关联的CORESETPoolIndex;从至少一个SRS资源集中,选出在SRS资源集的高层参数中配置的CORESETPoolIndex与所述CG配置或者所述SRI关联的CORESETPoolIndex相同的SRS资源集,作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置与其关联的CORESETPoolINdex取值,SRS resource set也与一个CORESETPoolINdex取值关联,因此,与相同CORESETPoolINdex取值关联的CG配置或SRI指示和SRS resource set是关联的。如果一个CG配置包括一个SRI指示(srs-ResourceIndicator或srs-ResourceIndicator2-r17),则CG配置关联的CORESETPoolIndex取值所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的CORESETPoolIndex取值,即关联不同的SRS resource set。
在一些实施方式中,指定参数包括SRS资源集索引时,基于所述关联关系确定SRS资源集,可实施为:将所述CG配置或者所述SRI关联的SRS资源集索引对应的SRS资源集,作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置与其关联的SRS资源集索引,该SRS资源集索引可以对应高层参数srs-ResourceSetId。如果一个CG配置包括一个SRI指示,则CG配置关联的SRS资源集索引所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的SRS资源集索引,即关联不同的SRS resource set。
在一些实施方式中,指定参数包括所述终端设备的能力值索引时,基于 所述关联关系确定SRS资源集,可实施为:确定所述CG配置或者所述SRI关联的所述终端设备的能力值索引对应的SRS资源集,作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置与其关联的终端设备的能力值索引,SRS resource set也与一个能力值索引关联,因此,与相同能力值索引关联的CG配置或SRI指示和SRS resource set是关联的。如果一个CG配置包括一个SRI指示,则CG配置关联的能力值索引所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的能力值索引,即关联不同的SRS resource set。
在一些实施方式中,所述指示参数包括TCI状态配置时,基于所述关联关系确定SRS资源集,可实施为:确定所述CG配置或者所述SRI关联的TCI状态配置;确定所述TCI状态配置关联的SRS资源集作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置关联的第几个TCI状态,SRS resource set也与一个TCI状态关联(如配置或指示的第一TCI状态,或第二个TCI状态等),因此,与相同TCI状态关联的CG配置或SRI指示和SRS resource set是关联的。如果一个CG配置包括一个SRI指示,则CG配置关联的TCI状态所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的TCI状态,即关联不同的SRS resource set。
在一些实施方式中,当指定参数包括CG索引时,所述关联关系可以包括:所述CG配置中配置的CG索引与SRS资源集之间的关联关系。
其中,CG配置中配置的CG索引可以理解为指定RRC参数。
在一种可能的实施方式中,所述CG配置中配置的CG索引与SRS资源集之间的关联关系,包括:奇数CG索引对应网络设备配置的两个SRS资源集中的一个SRS资源集,偶数CG索引对应另一个SRS资源集。
该实施方式中,CG索引(configuredGrantConfigIndex-r16)与SRS resource set索引有预定义的对应关系,奇数CG索引对应第一个SRS resource set,偶数CG索引对应第二个SRS resource set。根据CG配置中配置的CG索引可以确定对应的SRS resource set。
在一些实施方式中,当指定参数包括指定RRC参数时,所述关联关系可以包括:所述CG配置中配置的指定RRC参数与SRS资源集之间的关联关系。
在一种可能的实施方式中,所述CG配置中包括关联的另一CG的第二CG索引,所述CG配置中配置的指定RRC参数与SRS资源集之间的关联关系,包括以下两种情况:
第一种情况,若所述CG配置对应的第一CG索引小于所述第二CG索引,则所述第一CG索引对应网络设备配置的两个SRS资源集中的第一个SRS资源集。
第二种情况,若所述CG配置对应的第一CG索引大于所述第二CG索引,则所述第一CG索引对应网络设备配置的两个SRS资源集中的第二个SRS资源集。
其中,CG配置中关联的另一CG的第二CG索引可以理解为指定RRC参数,或者第一CG索引和第二CG索引均理解为指定的RRC参数,分别与两个SRS资源集关联。
另外,当所述CG配置中未包括与其它CG的关联信息,即所述CG配置对应的CG没有关联其它CG时,所述关联关系包括:所述CG配置对应网络设备配置的多个SRS资源集中的一个SRS资源集,例如第一个SRS资源集。
该实施方式中,网络设备可以预先建立2个CG之间的关联,例如,网络设备配置部分CG组合可以做同时传输(或重复传输),示例性的,在CG配置中包括该CG的ID,以及与该CG联合进行同时传输或重复传输的CG ID,如以下配置代码:

其中,associatedconfiguredGrantConfigIndex用于配置关联的其它CG的CG索引。
例如,与其它CG有关联关系的2个CG中,具有较低CG索引的CG可以与第一个SRS resource set关联,具有较高CG索引的CG可以与第二个SRS resource set关联。没有关联其它CG的CG可以只与第一个SRS resource set关联。
在另一种可能的实施方式中,所述CG配置中配置的指定RRC参数与SRS资源集之间的关联关系包括:
所述CG配置中配置的第一RRC参数对应网络设备配置的两个SRS资源集中的一个SRS资源集,第二RRC参数对应另一个SRS资源集;其中,所述CG配置中配置所述第一RRC参数和所述第二RRC参数中的一个或两个。
例如,第一RRC参数对应第一个SRI指示(srs-ResourceIndicator),所述第一个SRI指示对应第一个SRS resource set,第二RRC参数对应第二个SRI指示(srs-ResourceIndicator2-r17),所述第二个SRI指示对应第二个SRS resource set。网络设备可以在CG配置下仅配置srs-ResourceIndicator或srs-ResourceIndicator2-r17,或者同时配置srs-ResourceIndicator和srs-ResourceIndicator2-r17。
步骤203,基于所述SRS资源集确定SRS资源。
实施时,基于CG配置中的SRI确定SRS资源。SRI(srs-ResourceIndicator或srs-ResourceIndicator2-r17)指示的是与其关联的SRS resource set中的SRS 资源。
步骤204,基于所述SRS资源发送PUSCH。
综上所述,基于预定义的规则的实现方式可有多种,实施时可根据实际需求确定采用的预定义的规则。
本申请实施例中,为终端设备基于预定义的规则确定SRS resource set的方法,还可以应用于DCI调度PUSCH和CG配置传输PUSCH同时进行的场景,在该场景下,针对DCI调度PUSCH,可以通过上述实施例中的图1所示的方法确定SRS resource set;针对CG配置传输PUSCH,可以通过上述实施例中的图2所示的方法确定SRS resource set,在此不再赘述。
终端设备可以选择2个CG进行同时传输或重复传输,此时,可以选择与不同SRS resource set关联的CG进行传输。终端设备还可以选择1个CG与DCI调度进行同时传输或重复传输,此时,选择的CG和DCI调度分别与不同的SRS resource set关联。终端设备还可以选择关联的2个或以上CG进行同时传输或重复传输。
二、基于网络设备的指示信息确定SRS resource set
如图3所示,为终端设备基于网络设备的指示信息确定SRS resource set的方法流程图,该方法应用于至少一个DCI调度物理PUSCH的场景,或者通过至少一个CG配置传输PUSCH的场景,还可以应用于DCI调度PUSCH和CG配置传输PUSCH同时进行的场景,包括以下步骤:
步骤301,网络设备为所述终端设备配置用于指示信道探测参考信号SRS资源集的指示信息;
步骤302,网络设备将所述指示信息发送给所述终端设备。
步骤303,终端设备在DCI中检测到或者获取到CG配置包含的SRI,则基于网络设备的指示信息,确定指定参数和信道探测参考信号SRS资源集之间的关联关系。
步骤304,终端设备根据关联关系确定SRS资源集。
所述网络设备的指示信息,用于确定指定参数与SRS资源集之间的关联关系;所述指定参数包括以下中的至少一种:CORESETPoolIndex、检测到的用于传输所述DCI或PDCCH的CORESET、TCI状态配置、所述DCI中的指定信息域、所述终端设备的能力值索引、SRS资源集索引、CG索引、指定无线资源控制RRC参数。
由此,在确定SRS resource set时,根据网络侧的指示信息中的具体参数来确定,基于网络侧的指示能准确的理解SRS resource set。
实施时,所述网络设备的指示信息包括以下1)到8)中的至少一种:
1)、在SRS资源集的高层参数中配置的CORESETPoolIndex;由此,实施时通过SRS resource set的高层参数即可获得指示信息指示的SRS resource set。
当指示信息是SRS资源集的高层参数中配置的CORESETPoolIndex时,关联关系可理解为CORESETPoolIndex和SRS资源集的关联关系。
该情况下,终端设备在DCI中检测到SRI时,所述终端设备根据关联关系确定SRS资源集可实施为:
检测用于传输所述DCI或PDCCH的CORESET;
获取所述CORESET的CORESETPoolIndex;
从至少一个SRS资源集中选出在SRS资源集的高层参数中配置的CORESETPoolIndex与所述CORESET的CORESETPoolIndex相同的SRS资源集作为用于传输所述PUSCH的SRS资源集。
在另一种情况下,终端设备获取到CG配置中包含的SRI时,确定SRS资源集可实施为:
获取所述CG配置或者所述SRI关联的CORESETPoolIndex;
从至少一个SRS资源集中选出在SRS资源集的高层参数中配置的CORESETPoolIndex与所述CG配置或者所述SRI关联的CORESETPoolIndex相同的SRS资源集,作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置与其关联的 CORESETPoolINdex取值,SRS resource set也与一个CORESETPoolINdex取值关联,因此,与相同CORESETPoolINdex取值关联的CG配置或SRI指示和SRS resource set是关联的。如果一个CG配置包括一个SRI指示(srs-ResourceIndicator或srs-ResourceIndicator2-r17),则CG配置关联的CORESETPoolIndex取值所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的CORESETPoolIndex取值,即关联不同的SRS resource set。
下面举个例子说明如何在SRS resource set相关高层参数中配置CORESETPoolIndex参数:
该例子中,SRS resource set对应的高层参数为SRS-ResourceSet,配置在参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2中,且SRS resource set的用途(usage)配置为‘codebook’或‘nonCodebook’。参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2分别对应DCI格式0_1或0_2,可以配置2个或以上usage为‘codebook’或‘nonCodebook’的SRS resource set。所述SRI为‘SRS resource indicator’域或‘Second SRS resource indicator’域,可以由DCI格式0_1或0_2承载,DCI格式0_0中无SRI。
作为一种可选的实施方式,在SRS resource set对应的高层参数SRS-ResourceSet下面配置关联的CORESETPoolIndex参数。
例如,只在usage为‘codebook’或‘nonCodebook’的SRS resource set对应的高层参数SRS-ResourceSet下面配置关联的CORESETPoolIndex参数,也就是说,在SRS-ResourceSet下面配置CORESETPoolIndex参数的条件是SRS-ResourceSet的usage为‘codebook’或‘nonCodebook’。对于usage为‘codebook’或‘nonCodebook’的SRS resource set,如果未配置参数CORESETPoolIndex,也可以认为CORESETPoolIndex的取值为0。当PUSCH传输方式相关参数txConfig被配置为‘codebook’或‘nonCodebook’,且DCI在CORESETPoolIndex取值为k(k=0或1)的CORESET中被检测到时,终 端可以确定SRI关联的SRS resource set为CORESETPoolIndex取值为k,同时usage也为‘codebook’或‘nonCodebook’的SRS resource set。
上述方法对于高层参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2中配置一个或多个usage为‘codebook’或‘nonCodebook’的SRS resource set的情况均适用。终端期望一个BWP或一个小区内usage为‘codebook’或‘nonCodebook’的CORESETPoolIndex取值为k的SRS resource set不超过1个,或者高层参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2中配置的usage为‘codebook’或‘nonCodebook’的CORESETPoolIndex取值为k的SRS resource set不超过一个。如果高层参数srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2中配置的usage为‘codebook’或‘nonCodebook’的CORESETPoolIndex取值为k的SRS resource set超过1个,可以采用本方法和后面介绍的其它方法联合确定DCI里的SRI关联的SRS resource set。
另外,也可以在usage为‘beamManagement’或‘antennaSwitching’的SRS resource set内配置参数CORESETPoolIndex,以表示该SRS resource set与CORESET(TRP)的关联,用于上行波束管理或上行天线切换,便于后续的多panel传输。
在本实施例中,如无特殊说明,SRS resource set均指的是usage为‘codebook’或‘nonCodebook’的SRS resource set。
2)、若指示信息为CORESET配置的所述终端设备的能力值索引;由此,通过在CORESET下面配置终端设备的能力值索引,终端设备即可根据能力值索引确定SRS resource set。
终端设备在DCI中检测到SRI时,确定SRS resource set可实施为:
检测用于传输所述DCI或PDCCH的CORESET;
获取为所述CORESET配置的所述终端设备的能力值索引;
确定为所述CORESET配置的所述终端设备的能力值索引对应的SRS资源集,作为用于传输所述PUSCH的SRS资源集。
例如,每个CORESET下配置一个参数Capability[Set]Index,UE根据Capability[Set]Index对应的SRS端口数确定相对应的SRS resource set(对应方式二中第3种情况)。
每个CORESET下面配置一个panel相关的能力值(如参数Capability[Set]Index),表示该CORESET可以调度UE的某个panel进行传输。假如,srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2中配置的usage为‘codebook’或‘nonCodebook’的SRS resource set中包含的SRS端口数不同时,如SRS resource set 5(srs-ResourceSetId=5)包含的SRS端口数为2,SRS resource set 2(srs-ResourceSetId=2)包含的SRS端口数为4,能力值1对应SRS最大端口数为4,能力值2对应SRS最大端口数为4,当UE在某个CORESET内检测到具有SRI的DCI后,可以根据所述关联关系确定SRI关联的能力值(如能力值2),进而确定关联的SRS端口数(4端口),进而间接确定SRI关联的SRS resource set(即SRS resource set 2)。
CORESETPoolIndex取值为相同值的CORESET可以对应相同的能力值,或UE期望具有相同CORESETPoolIndex参数的CORESET关联的能力值数值相同,这样可以建立TRP和panel的固定关联,表示一个TRP仅对具有一种能力值的panel进行调度。CORESETPoolIndex取值不同的CORESET可以对应不同的能力值,这样可以保证多个TRP调度的panel不同,不会造成冲突,即不会出现多个TRP在相同时刻调度同一个panel,避免出现网络侧调度超过终端能力的情况。
3)、指示信息包括所述DCI中的指定信息域。
一些可能的实施方式中,所述DCI中的指定信息域可包括以下至少一种:
用于指示SRS资源集的第一信息指示域;
用于指示所述终端设备的能力值索引的第二信息指示域;
用于指示所述TCI状态的第三信息指示域。
例如,第一信息指示域可标识SRS resource set的标识,由此基于第一信息指示域即可确定SRS resource set。
再例如,基于第二信息指示域确定终端设备的能力值索引,然后基于预先建立的能力值索引和SRS resource set之间的关联关系,可确定要采用的SRS resource set。
再例如,第三信息指示域可确定网络设备指示的TCI状态,然后预先建立有不同TCI状态关联的SRS resource set,由此,可基于DCI中的TCI状态确定要采用的SRS resource set。
再例如,针对不同指示域结合使用的情况,一种可能的实施例为DCI中的TCI域指示2个TCI状态,然后使用SRS resource set域或其它信息域指定使用其中一个TCI状态位(即单TRP传输),那么TCI状态域指示的2个TCI状态只有一个会生效。基于预设规则确定生效的TCI状态关联的SRS resource set用于传输PUSCH。
基于上述DCI中的指定信息域,终端设备确定SRS资源集可实施为:
获取所述DCI中的所述指定信息域;然后,将所述指定信息域指示的SRS资源集作为用于传输所述PUSCH的SRS资源集。
此外,由于2个TRP独立进行调度,各自独立进行SRS resource set指示或能力值指示,可能会导致2个DCI指示了相同的SRS resource set,进而指示相同的SRS资源,这样2个TRP调度的PUSCH可能均使用与SRS端口相同的端口去发送PUSCH,是有可能超出UE的能力的。例如,2个TRP均指示终端使用4端口的panel或使用4端口去发送具有4个数据流PUSCH,而UE仅有一个4端口的panel,是不能进行合计8个数据流的传输的。然而,对有些UE而言,panel个数较多,TxRU数量也较多,即使2个TRP调度UE使用相同的SRS resource set或SRS资源作为PUSCH的传输端口,UE也有能力按照网络侧的调度进行发送。因此,UE可以预先发送是否支持所述DCI中的指定信息域的能力信息给所述网络设备。若UE没有相关能力,网络设备不能为UE使用该方法。
在终端确定DCI关联的SRS资源集后,根据SRI的指示确定相应的SRS资源用于PUSCH传输。对于基于codebook的PUSCH传输,在DCI中还会包含TPMI域,用于指示终端发送预编码码字及相应的传输层数(layer)。若终端能力较低,可能会出现2个DCI调度的PUSCH端口数大于终端可以发送的最大端口数,或者2个DCI调度的数据层数超过终端可以发送的最大数据层数。为避免这一情况,作为一种可行的实施方式,本申请还可以对DCI的调度进行限制,如限制每个DCI调度的PUSCH的最大端口数,或者限制每个DCI调度的最大数据层数。例如,终端最多支持4个数据层传输,可以限定每个DCI调度的数据层数不超过2,或者CORESETPoolIndex取值为0或未配置CORESETPoolIndex的COERSET内发送的DCI调度的PUSCH数据层数不超过3,CORESETPoolIndex取值为1的COERSET内发送的DCI调度的PUSCH数据层数不超过1等。
又或者,当2个DCI调度的数据层数之和大于终端所支持的最大层数(如Nmax)时,将指定DCI调度的PUSCH减为Nmax-N1层,其中N1为另一个DCI调度的数据层。例如,将CORESETPoolIndex取值为0或未配置CORESETPoolIndex的COERSET内发送的DCI调度的PUSCH数据层数,按照DCI指示的TPMI发送;将CORESETPoolIndex取值为1的COERSET内发送的DCI调度的PUSCH数据层数减为Nmax-N1层。在减小数据后,可以通过UCI反馈或其它上行信令等将数据流缩减事件通知给网络设备,例如,通知删减后的数据流数,还可以额外指示当前数据流对应的预编码码字,该预编码码字也可以是在协议中预先规定的码字。例如针对秩为1,2,3,4的PUSCH传输分别定义一个默认的预编码码字,用于数据流删减时使用。
下面就前述三种指定信息域分别如何确定SRS资源集分别进行说明:
(1)、基于第一指定信息域:
例如,通过第一指定信息域即SRS resource set域指示相应的SRS resource set,可实施为:
当配置2个SRS resource set(usage为‘codebook’或‘noncodebook’) 时,SRS resource set域位宽为1比特(bit),仅用于指示第一个SRS resource set或第二个SRS resource set。实施时,比特域的索引和指示的SRS resource set的关系,可如表2所示:
表2
当配置3个SRS resource set时,SRS resource set域位宽为2bit,采用表3进行SRS resource set指示。其关系如表3所示:
表3
类似的,当配置4个SRS resource set时,SRS resource set域位宽为2bit,采用表4进行SRS resource set指示。
表4
基于以上各表格所述情况,UE在接收到SRI后,根据SRS resource set 指示域确定SRI关联的SRS resource set,并根据SRI的指示确定相应的SRS资源,并使用与所述SRS资源相同的天线端口去发送PUSCH。
(2)基于第二指定信息域:
例如,第二指定信息域用于指示能力值,UE根据能力值关联的最大SRS port数确定对应的SRS resource set。
当UE上报1个能力值时,能力值指示域(即第二信息指示域)位宽为0比特,UE期望网络侧配置usage为‘codebook’或‘noncodebook’的SRS resource set数量为1,且DCI中的SRI与该SRS resource set关联,即指示该SRS resource set中的SRS资源。
当UE上报2个能力值时,能力值指示域位宽为1比特,码点‘0’和‘1’分别对应第一个能力值和第二个能力值。
当UE上报3个能力值时,能力值指示域位宽为2比特,码点‘00,01’和‘10’分别对应第一个,第二个和第三个能力值,码点‘11’为预留状态。
当UE上报4个能力值时,能力值指示域位宽为2比特,码点‘00,01’,‘10’和‘11’分别对应第一个,第二个,第三个和第四个能力值。
UE可以根据DCI中指示的能力值,确定相应的SRS最大端口数,进而根据SRS最大端口数确定相应的SRS resource set。通过这种方式,各个TRP调度的panel是可以动态变化的。
第二信息指示域可以是一个新的信息域,也可以利用现有的DCI信息域,如TCI指示域,SRS resource set指示域等。
由于2个TRP独立进行调度,各自独立进行SRS resource set指示或能力值指示,可能会导致2个DCI指示了相同的SRS resource set,进而指示相同的SRS资源,这样2个TRP调度的PUSCH可能均使用与所述SRS端口相同的端口去发送,是有可能超出UE的能力的。例如,2个TRP均指示终端使用4端口的panel或使用4端口去发送具有4个数据流的PUSCH,而UE仅有一个4端口的panel,是不能进行合计8个数据流的传输的。然而,对应有些UE而言,panel个数较多,TxRU数量也较多,即使2个TRP调度UE使 用相同的SRS resource set或SRS资源作为PUSCH的传输端口,UE也有能力按照网络侧的调度进行发送。因此,UE可以预先上报是否支持动态指示SRS resource set相关信息的能力。若UE没有相关能力,网络侧不能为UE使用该方法。
作为一种可行的实施方式,还可以在调度上做一定的限制,例如2个DCI调度的PUSCH传输方案不同的情况,如一个是基于codebook的PUSCH传输,另一个是non-codebook based PUSCH传输,两种usage下SRS resource set是不冲突的。在这种2个DCI调度的PUSCH传输方案不同的情况下,网络侧为UE配置2个txConfig参数,例如txConfig和txConfig-r18,分别对应CORESETPoolIndex取值为0和1的情况。
(3)基于第三信息指示域:
例如,DCI中的TCI域指示TCI状态,UE根据TCI状态确定对应的SRS resource set。与基于第二信息指示域的方法类似,可以检测DCI中的TCI域,然后获取TCI域指示的TCI状态,然后根据预先定义的TCI状态和SRS resource set的关联关系,确定采用的SRS resource set。
4)、指示信息为传输配置指示TCI状态配置;由此,通过TCI状态配置即可隐式的指示SRS resource set。
作为一种可行的实施方式,终端设备在DCI中检测到SRI时,确定SRS资源集,可实施为:
确定与所述DCI关联的TCI状态配置;
确定所述TCI状态配置关联的SRS资源集作为用于传输所述PUSCH的SRS资源集。
本申请实施例中,所述DCI关联的TCI状态配置包括以下至少一种:
MAC-CE信令激活的至少一个TCI状态;
例如,使用MAC-CE信令激活多组TCI状态组合,而后使用DCI信令,指示其中的一组TCI状态组合。每组TCI状态组合可以是包含上行TCI状态和/或下行TCI状态,其中上行TCI状态和下行TCI状态可以是一个或多个, 多个的情况下分别对应多个信道或信息(例如对应多TRP或多个panel传输)。当MAC-CE信令激活TCI状态时,可以携带SRS资源集索引,表示TCI状态可以作用于对应的SRS资源集传输上。网络侧可以针对每个配置的SRS资源集分别激活相应的TCI状态,例如,MAC-CE信令中的所有TCI状态组合均和一个SRS资源集关联。MAC-CE信令里携带的SRS资源集索引可以是SRS资源集的绝对索引,也可以是相对索引。此外,MAC-CE信令中还会携带CORESETPoolIndex值,由此建立DCI和TCI状态激活MAC-CE信令之间的关联。具体地,终端检测到DCI后,根据DCI所在CORESET或CORESET的参数CORESETPoolIndex确定相应的MAC-CE信令,进而确定关联的SRS资源集。又例如,MAC-CE信令中的每个TCI状态组合关联一个SRS资源集,在这种情况下,终端可以根据DCI信令中指示的TCI状态组合(也即TCI状态的码点,如‘011’)确定相应的关联的SRS资源集。
当前生效(可理解为已生效)的至少一个TCI状态;
所述DCI所在的CORESET或所述CORESET配置的CORESETPoolIndex关联的TCI状态。
作为一种可行的实施方式,终端设备获取到CG配置中包含的SRI时,确定SRS资源集,可实施为:
确定所述CG配置或者所述SRI关联的TCI状态配置;
确定所述TCI状态配置关联的SRS资源集作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置关联的第几个TCI状态(如配置或指示的第一TCI状态,或第二个TCI状态等),SRS resource set也与一个TCI状态关联,因此,与相同TCI状态关联的CG配置或SRI指示和SRS resource set是关联的。如果一个CG配置包括一个SRI指示,则CG配置关联的TCI状态所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的TCI状态,即关联不同的SRS resource set。
在一些实施方式中,所述TCI状态配置关联的SRS资源集包括以下至少一种:
RRC信令配置的TCI状态关联的一个SRS资源集的索引;
MAC CE激活的TCI状态信令中包含的SRS资源集的索引。
例如,网络侧配置不同的TCI状态配置与SRS resource set的关联,进而UE通过TCI状态配置确定SRI作用的(关联的)SRS resource set。
一种可能的实施方式中,RRC配置TCI状态时,每个TCI状态关联一个SRS resource set的索引。
另一种可能的实施方式中,MAC CE激活TCI状态时,包含SRS resource set索引(类似于Rel-16TCI激活/更新MAC CE中携带CORESETPoolIndex参数类似)。
在一种可能的实施方式中,假设使用(unified)TCI状态指示,每个TCI状态位对应一个SRS resource set(预定义的规则),当一个DCI中的一个TCI状态位调度一个SRS resource set时,另一个TCI状态位的指示为特定值,如‘111’,相当于预留位,终端根据TCI状态指示确定SRI作用的SRS resource set。
在一种可能的实施方式中,每个TCI状态指示位对应一个SRS资源集,当TCI状态位指示为第一特定值(如‘111’)或预留值(‘Reserved’)时,则表示不使用该TCI状态位。当TCI状态位指示为第二特定值(如‘000’到‘110’)时,则表示该TCI状态位指示了一个具体的TCI状态。因此终端可以根据DCI中的TCI的指示,以及TCI状态位与SRS资源集的关联,确定所述DCI作用的SRS资源集,进而确定相应的SRS资源用于PUSCH传输。
本申请实施例中,网络设备除了基于上述方法使用DCI中的指定信息域进行指示,网络设备还可以指示SRS资源集索引给终端设备,进而终端设备可以根据DCI和该资源集索引确定SRS资源集。
一种可能的实施方式中,网络设备指示的SRS资源集索引包括为CORESET配置的SRS资源集索引。此时,终端设备可以检测用于传输所述 DCI或PDCCH的CORESET;将所述CORESET的SRS资源集索引对应的SRS资源集作为用于传输所述PUSCH的SRS资源集。
例如,每个CORESET下配置关联的SRS resource set索引,每个CORESET可以关联usage为codebook和/或non-codebook的SRS resource set。可以在CORESET对应的高层参数ControlResourceSet内配置关联的SRS resource set索引。所述SRS resource set索引可以是高层参数srs-ResourceSetId,即SRS resource set的绝对索引(如0-15,在一个BWP内进行排序)。还可以是SRS resource set的相对索引。例如相对索引为第一SRS resource set或第二SRS resource set,这两个索引分别对应srs-ResourceSetToAddModList或srs-ResourceSetToAddModListDCI-0-2中配置的usage为‘codebook’或‘nonCodebook’的SRS resource set中具有较低索引或较高索引的SRS resource set。
终端设备在检测到具有SRI的DCI后,可以根据DCI所在的CORESET确定SRI关联的SRS resource set,进而确定相应的SRS资源。具有相同CORESETPoolIndex参数的CORESET关联的SRS resource set索引可以相同也可以不同,如果相同,则表示一个TRP关联一个SRS resource set,即该TRP仅调度该SRS resource set进行传输。如果不同,则表示一个TRP可以调度多个SRS resource set进行传输。
5)、指示信息包括所述CG配置或者所述SRI关联的SRS资源集索引,终端设备获取到CG配置中包含的SRI时,确定SRS资源集,可实施为:
将所述CG配置或者所述SRI关联的SRS资源集索引对应的SRS资源集,作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置与其关联的SRS资源集索引,该SRS资源集索引可以对应高层参数srs-ResourceSetId。如果一个CG配置包括一个SRI指示,则CG配置关联的SRS资源集索引所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的SRS资源集索引,即关联不 同的SRS resource set。
6)、指示信息包括所述CG配置或者所述SRI关联的所述终端设备的能力值索引,终端设备获取到CG配置中包含的SRI时,确定SRS资源集,可实施为:
确定所述CG配置或者所述SRI关联的所述终端设备的能力值索引对应的SRS资源集,作为用于传输所述PUSCH的SRS资源集。
其中,在一个CG配置或一个SRI指示下可以配置与其关联的终端设备的能力值索引,SRS resource set也与一个能力值索引关联,因此,与相同能力值索引关联的CG配置或SRI指示和SRS resource set是关联的。如果一个CG配置包括一个SRI指示,则CG配置关联的能力值索引所对应的SRS resource set,即为SRI指示关联的SRS resource set;如果一个CG包括多个SRI指示,则每个SRI指示可以分别关联不同的能力值索引,即关联不同的SRS resource set。
7)、指示信息包括所述CG配置中关联的CG索引,所述关联关系可以包括:所述CG配置中配置的CG索引与SRS资源集之间的关联关系。
其中,CG配置中配置的CG索引可以理解为指定RRC参数。
终端设备获取到CG配置中包含的SRI时,可以基于以下方式确定CG配置中配置的CG索引与SRS资源集之间的关联关系,进而基于该关联关系确定SRS资源集:
奇数CG索引对应网络设备配置的两个SRS资源集中的一个SRS资源集,偶数CG索引对应另一个SRS资源集。
8)、指示信息包括所述CG配置中关联的指定RRC参数时,所述关联关系可以包括:所述CG配置中配置的指定RRC参数与SRS资源集之间的关联关系。
终端设备获取到CG配置中包含的SRI时,可以基于以下两种情况确定CG配置中配置的指定RRC参数与SRS资源集之间的关联关系,进而基于该关联关系确定SRS资源集:
第一种情况,若所述CG配置对应的第一CG索引小于所述第二CG索引,则所述第一CG索引对应网络设备配置的两个SRS资源集中的第一个SRS资源集。
第二种情况,若所述CG配置对应的第一CG索引大于所述第二CG索引,则所述第一CG索引对应网络设备配置的两个SRS资源集中的第二个SRS资源集。
其中,CG配置中关联的另一CG的第二CG索引可以理解为指定RRC参数,或者第一CG索引和第二CG索引均理解为指定的RRC参数,分别与两个SRS资源集关联。
例如,与其它CG有关联关系的2个CG中,具有较低CG索引的CG可以与第一个SRS resource set关联,具有较高CG索引的CG可以与第二个SRS resource set关联。没有关联其它CG的CG可以只与第一个SRS resource set关联。
步骤305,终端设备基于所述SRS资源集确定SRS资源;
步骤306,终端设备基于所述SRS资源发送所述PUSCH。
在本申请实施例中,网络设备可以为所述终端设备配置两个PUSCH传输参数(如txconfig和txconfig_r18),所述两个PUSCH传输参数取值相同或不同。由此,2个DCI或PDCCH(即TRP)可以独立调度终端设备采用不同的传输方法进行传输,如分别调度终端设备采用基于codebook(码本)的PUSCH传输方式和基于non-codebook(非码本)的PUSCH传输方式进行传输,增加网络设备调度的灵活性并提升系统性能。在这种情况下,由于每个DCI调度的PUSCH传输方法不同,对应不同的SRS资源集,在使用DCI信令中的‘SRS resource set’指示域或其它信息域动态指示SRS资源集时,2个DCI关联的SRS资源集是不同的,即分别是usage为码本和非码本的SRS资源集,在这种情况下,2个DCI信令指示的SRS资源集是不会发生冲突的,即不会出现2个DCI指示SRI资源对应的PUSCH传输超过终端能力的情况。
