Description
本申请要求在2024年2月6日提交中国国家知识产权局、申请号为2024101682196的中国专利申请的优先权,发明名称为“信道状态信息CSI优先级确定方法、相关设备及系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及无线通信技术领域,尤其涉及CSI优先级确定方法、相关设备及系统。
R18是第五代(5th Generation,5G)移动通信技术演进阶段的第一个版本,R18移动性(R18 Mobility)中引入了L1/L2触发移动性(L1/L2 Triggered Mobility,LTM)的概念,即通过L1测量上报以及L1/L2信令指示终端设备进行小区切换。当终端设备从一个小区的覆盖区域移动到另一个小区的覆盖区域,终端设备将执行服务小区的变更。相对于传统的基于L3测量并由无线资源控制(radio resource control,RRC)信令触发服务小区的变更的过程,LTM可以降低业务中断时间,即降低整个移动性过程中的时延。
在整个LTM流程中,L1测量上报可以称为LTM信道状态信息(channel state information,CSI)上报,LTM CSI上报是指,终端设备将用于LTM的CSI报告(即L1测量报告)发送给网络设备。在进行LTM CSI上报之前,终端设备需要确定用于LTM的CSI报告关联的优先级,以确定LTM CSI上报的先后顺序。
本申请提供了一种CSI优先级确定方法、相关设备及系统,终端设备可以确定用于L1/2触发移动性LTM的CSI报告关联的优先级,该优先级可以由以下参数确定:用于LTM的CSI报告的类型y、用于LTM的CSI报告是否携带小区波束发送的参考信号接收功率RSRP或小区波束发送的参考信号在终端设备侧的信干噪比SINR的指示值k、第一候选小区索引c’、候选小区个数Ncells’、用于LTM的CSI报告的报告配置索引s’、用于LTM的CSI报告的报告配置个数Ms’,其中第一候选小区索引c’不同于终端设备所在服务小区的索引。

通过实施第一方面提供的方法,终端设备可以通过参数y、参数k、参数c’、参数Ncells’、参数s’、参数Ms’确定用于LTM的CSI报告关联的优先级。
结合第一方面,在一些实施例中,优先级PriLTM-CSI基于下述公式确定:PriLTM-CSI(y,k,c’,s’)=2·Ncells’·Ms’·y+Ncells’·Ms’·k+Ms’·c’+s’,优先级PriLTM-CSI的值越小,用于LTM的CSI报告关联的优先级越高。

结合第一方面,在一些实施例中,第一候选小区索引c’的值与是否配置了第一配置参数有关,具体包括:如果用于LTM的CSI报告配置了第一配置参数,候选主小区组内第一候选小区索引c’为0,或者,候选辅小区组内第一候选小区索引c’为SpCell的索引;或者,如果用于LTM的CSI报告未配置第一配置参数,第一候选小区索引c’等于用于LTM的CSI报告关联的下行参考信号所在候选小区的最小索引,或者,第一候选小区索引c’等于用于LTM的CSI报告关联的下行参考信号所在候选小区的最大索引。
不限于此,如果用于LTM的CSI报告未配置第一配置参数,第一候选小区索引c’可以等于用于LTM的CSI报告关联的下行参考信号所在任一候选小区的索引。
结合第一方面,在一些实施例中,第一候选小区索引c’为0或者特殊小区SpCell的索引;非用于LTM的CSI报告关联的优先级Prii-CSI基于下述公式确定:Prii-CSI(y,k,c,s)=2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s,其中,c=终端设备所在服务小区的索引+1,Ncells是服务小区的最大数量,s是非用于LTM的CSI报告的报告配置索引,Ms是非用于LTM的CSI报告的报告配置个数。
进一步地,用于LTM的CSI报告与非用于LTM的CSI报告可能会重叠出现,例如,用于LTM的CSI报告与非用于LTM的CSI报告在同一个PUCCH上复用。在这种情况下,需要区分用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级。可选地,可以使得用于LTM的CSI报告关联的优先级高于非用于LTM的CSI报告关联的优先级。具体地,重新确定用于LTM的CSI报告关联的优先级PriLTM-CSI计算公式中的参数c’,重新确定之后的参数c’可以为0或者特殊小区SpCell的索引。具体地,重新确定非用于LTM的CSI报告关联的优先级Prii-CSI计算公式中的参数c,重新确定之后的参数c可以为终端设备所在服务小区的索引值+1。

在本申请实施例中,为了区分用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级,可以重新确定参数Ncells’,重新确定之后的参数Ncells’可以为重新确定之前的参数Ncells’的值+1。其中,重新确定之前的参数Ncells’可以是通过高层信令配置的,例如Ncells’可以等于高层配置参数maxNrofServingCells的值。可以重新确定参数Ncells,重新确定之后的参数Ncells可以为重新确定之前的参数Ncells的值+1。其中,重新确定之前的参数Ncells可以是通过高层信令配置的,例如Ncells可以等于高层配置参数maxNrofServingCells的值。

本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释,而非旨在限定本申请。
图1示出了本申请涉及的无线通信系统100。无线通信系统100可以工作在高频频段上,不限于长期演进(Long Term Evolution,LTE)系统,还可以是第五代移动通信(the 5th Generation,5G)系统、新空口(new radio,NR)系统,机器与机器通信(Machine to Machine,M2M)系统、未来的通信系统,如第六代移动通信系统等。如图1所示,无线通信系统100可包括:一个或多个终端设备200,一个或多个网络设备300,以及核心网(图中未示出)。
其中:终端设备200可以分布在整个无线通信系统100中,可以是静止的,也可以是移动的。在本申请的一些实施例中,终端设备200可以是用户设备(user equipment,UE)、移动设备、移动台(mobile station)、移动单元(mobile unit)、M2M终端、无线单元、远程单元、终端代理、移动客户端等等。
网络设备300可以为基站,基站可以用于与一个或多个终端设备进行通信,也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站,如接入点,之间的通信)。基站可以是时分同步码分多址(Time Division Synchronous Code Division Multiple Access,TD-SCDMA)系统中的基站收发台(Base Transceiver Station,BTS),也可以是LTE系统中的演进型基站(Evolutional Node B,eNB),以及5G系统、新空口(NR)系统中的基站。另外,基站也可以为传输点(Transmission and Reception Point,TRP)、接入点(Access Point,AP)、中心单元(Central Unit,CU)或其他网络实体,并且可以包括以上网络实体的功能中的一些或所有功能。
本申请实施例中,在该无线通信系统100中终端设备200与网络设备300可以进行LTM操作。示例性地,终端设备200可以进行LTM CSI上报(即L1测量上报),LTM CSI上报是指,终端设备200将用于LTM的CSI报告(即L1测量报告)发送给网络设备300。其中,用于LTM的CSI报告可用于指示用于LTM的信道状态,以使网络设备300决定是否进行小区切换。在LTM CSI上报之前,终端设备200可以确定用于LTM的CSI报告关联的优先级,以确定LTM CSI上报的先后顺序。
网络设备300可以接收来自终端设备200的用于LTM的CSI报告,并基于接收到的用于LTM的CSI报告做出是否进行小区切换的决策。在确定进行小区切换之后,网络设备300可以向终端设备200发送小区切换信令,该小区切换信令可用于触发终端设备200从当前驻留的小区(即服务小区,也可称为源小区)切换到另一个小区(即目标小区),其中,该目标小区是从终端设备200所在服务小区相邻(例如与服务小区的距离小于100米)的候选小区中选择的小区。
R18是5G移动通信技术演进阶段的第一个版本,R18移动性(R18 Mobility)中引入了L1/L2触发移动性(L1/L2 Triggered Mobility,LTM)的概念,LTM是指通过L1测量上报以及L1/L2信令指示终端设备200进行小区切换(即服务小区的变更)。当终端设备200从一个小区的覆盖区域移动到另一个小区的覆盖区域,终端设备200可以执行服务小区的变更。相对于传统的基于L3测量并由无线资源控制(radio resource control,RRC)信令触发服务小区的变更的过程,LTM无需执行完整的L2/L1的重置,从而可以降低业务中断时间以及减少信令开销,以达到低延迟、低开销和低数据中断时间的目标。
下面结合图2阐述本申请实施例提供的LTM的总体流程。
图2示出了本申请实施例提供的LTM的总体流程。下面展开:
S201.终端设备200进行预配置。
具体地,终端设备200可以向网络设备300发送消息1,该消息可用于指示网络设备300配置LTM,即指示网络设备300向终端设备200发送候选小区的RRC配置参数,从而使得终端设备200可以实现对于相应候选小区的预配置。其中,候选小区是指终端设备200可以进行LTM操作的候选的多个小区。
在一些实施例中,网络设备300可以通过如信令消息等方式将候选小区的RRC配置参数下发给终端设备200。
具体地,在接收到候选小区的RRC配置参数之后,终端设备200可以实现对于RRC配置参数所指示的相应候选小区的预配置。示例性地,RRC配置参数可以包括参考信号配置,终端设备200可以基于该参考信号配置对该参考信号配置所指示的候选小区的参考信号进行波束测量(即L1测量)。在完成对于相应候选小区的预配置之后,终端设备200可以存储相应候选小区的配置信息。
需要说明的是,上述配置信息可以存储于本地,也可以存储于云端,本申请实施例对此不作限定。
S202.终端设备200与网络设备300进行同步。
具体地,终端设备200与网络设备300可以进行下行同步与上行同步。以终端设备200与网络设备300进行下行同步为例,网络设备300可以向终端设备200发送下行同步信息(包括时间同步信息和频率同步信息)。在接收到来自网络设备300的下行同步信息之后,终端设备200可以基于该下行同步信息与网络设备300进行下行同步。其中,上述下行同步信息可以包括网络设备300下发的主同步信号序列、辅同步信号序列及参考信号序列,本申请实施例对于上述下行同步信息所包含的内容不作限定。
S203.终端设备200向网络设备300发送L1测量报告(用于LTM的CSI报告)。
在本申请实施例中,L1测量报告可以用于指示用于LTM的信道状态,以使网络设备300决定是否进行小区切换。该L1测量报告也可以称为波束测量结果,还可以称为用于LTM的CSI报告。其中,用于LTM的CSI报告包括但不限于候选小区的L1-RSRP、L1-SINR及其他自定义信息。其中,L1-RSRP是相应候选小区的波束发送的参考信号的接收功率(Reference Signal Receiving Power,RSRP),L1-SINR是相应候选小区的波束发送的参考信号在终端设备侧的信干噪比(Signal to Interference plus Noise Ratio,SINR)。
需要说明的是,终端设备200向网络设备300发送L1测量报告可以称为终端设备200进行L1测量上报,也可以称为终端设备200进行LTM CSI上报。
在本申请实施例中,在LTM CSI上报之前,终端设备200可以确定用于LTM的CSI报告关联的优先级,以确定LTM CSI上报的先后顺序。
S204.网络设备300进行LTM决策。
具体地,在接收到来自终端设备200的L1测量报告(用于LTM的CSI报告)之后,网络设备300可以基于该L1测量报告(用于LTM的CSI报告)决定是否进行小区切换。例如,当某个候选小区的L1测量结果(如RSRP)比当前服务小区更好,或者,当某个候选小区的L1测量结果(如RSRP)大于某一阈值,则网络设备300可以确定进行小区切换。
在本申请实施例中,小区切换可以是指将终端设备200从当前驻留的小区(即服务小区,也可称为源小区)切换到另一个小区(即目标小区)。其中,该目标小区是从终端设备200所在服务小区相邻(例如与服务小区的距离小于100米)的候选小区中选择的小区。
S205.网络设备300向终端设备200发送小区切换信令。
具体地,在确定进行小区切换之后,网络设备300可以向终端设备200发送小区切换信令,该小区切换信令可用于触发终端设备200从源小区切换到目标小区。
S206.终端设备200接入目标小区。
具体地,在接收到来自网络设备300的小区切换信令之后,终端设备200可以响应于该小区切换信令,将源小区切换到目标小区。
如前文所述,本申请实施例中,在LTM CSI上报之前,终端设备200可以确定用于LTM的CSI报告关联的优先级,以确定LTM CSI上报的先后顺序。用于LTM的CSI报告关联的优先级的确定方法,可以参考CSI报告关联的优先级的确定方法。下面介绍CSI报告关联的优先级的确定方法:
CSI报告关联的优先级可以基于下述公式确定:Prii-CSI(y,k,c,s)=2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s。该Prii-CSI的值越小,则CSI报告关联的优先级越高。其中,参数y是CSI报告的类型,有以下几种情况:当物理上行共享信道(physical uplink shared channel,PUSCH)上承载非周期的CSI报告时,y=0;当PUSCH上承载半持续的CSI报告时,y=1;当物理上行控制信道(physical uplink control channel,PUCCH)上承载半持续的CSI报告时,y=2;当PUCCH上承载周期的CSI报告时,y=3。参数k是CSI报告是否携带RSRP或SINR的指示值,当CSI报告携带RSRP或者SINR时,k=0;当CSI报告未携带RSRP或者SINR时,k=1。参数c是终端设备200所在服务小区的索引。参数Ncells指的是服务小区的最大数量,该参数Ncells是通过高层信令配置的,例如Ncells可以等于高层配置参数maxNrofServingCells的值,该高层配置参数maxNrofServingCells可用于指示服务小区的最大数量。参数s是指CSI报告的报告配置索引,可用于标识终端设备200发送的CSI报告中报告配置的参数集合。参数Ms指的是CSI报告的报告配置个数,该参数Ms是通过高层信令配置的,例如Ms可以等于高层配置参数maxNrofCSI-ReportConfigurations的值,该高层配置参数maxNrofCSI-ReportConfigurations可用于指示CSI报告的报告配置的最大个数。
需要说明的是,参数c的取值是唯一的。CSI报告的测量资源集(CSI-SSB-ResourceSet)包含一组资源块,每个资源块包含一个同步信号块(Synchronization Signal Block,SSB)以及相应的下行参考信号,每个资源块的下行参考信号都是终端设备200所在服务小区发射的,参数c取值于CSI报告关联的下行参考信号所在服务小区的索引。
为了考量CSI报告关联的优先级的确定方法是否适用于确定用于LTM的CSI报告关联的优先级,下面简要介绍LTM CSI上报的基本框架。
LTM CSI上报的基本框架可以包括LTM CSI上报的报告配置和LTM CSI上报的资源配置。每个LTM CSI上报的报告配置与用于信道测量的LTM CSI上报的资源配置相关联。并且,每个LTM CSI上报的报告配置可以包含时域行为的参数、候选小区的个数、每个候选小区的参考信号数量。其中,时域行为的参数可以指示用于LTM的CSI报告的类型,例如PUSCH上承载非周期的用于LTM的CSI报告、PUSCH上承载半持续的用于LTM的CSI报告、PUCCH上承载半持续的用于LTM的CSI报告、PUCCH上承载周期的用于LTM的CSI报告。此外,如果用于LTM的CSI报告配置了第一配置参数,例如spCellInclusion参数,则用于LTM的CSI报告可以包括与特殊小区(Special Cell,SpCell)相关联的L1测量结果。
图3示出了用于LTM的CSI报告的测量资源集的组成。用于LTM的CSI报告的测量资源集(LTM-CSI-SSB-ResourceSet)包含一个资源列表(LTM-CSI-SSB-ResourceList)和一个候选小区列表。其中,资源列表中的每个资源块均包含一个同步信号块以及相应的下行参考信号,每个资源块的下行参考信号来源的候选小区各不相同。如图3所示,资源块1的下行参考信号来源于候选小区1,资源块2的下行参考信号来源于候选小区2,资源块3的下行参考信号来源于候选小区3……
在本申请实施例中,终端设备200可以对来源于不同候选小区的下行参考信号进行L1测量,并将相应的L1测量报告发送给网络设备300。由于下行参考信号来自的候选小区不唯一,若采用CSI报告关联的优先级的计算公式来确定用于LTM的CSI报告关联的优先级,则参数c的取值不是唯一的。
因此,本申请实施例提供了一种CSI优先级确定方法,终端设备200可以确定用于LTM的CSI报告关联的优先级,该优先级可以由以下参数确定:用于LTM的CSI报告的类型y、用于LTM的CSI报告是否携带RSRP或SINR的指示值k、第一候选小区索引c’、候选小区个数Ncells’、用于LTM的CSI报告的报告配置索引s’、用于LTM的CSI报告的报告配置个数Ms’,其中第一候选小区索引c’不同于终端设备200所在服务小区的索引。
用于LTM的CSI报告关联的优先级PriLTM-CSI可以基于下述公式确定:PriLTM-CSI(y,k,c’,s’)=2·Ncells’·Ms’·y+Ncells’·Ms’·k+Ms’·c’+s’。该优先级PriLTM-CSI的值越小,则用于LTM的CSI报告关联的优先级越高。其中,参数y的取值方式与CSI报告关联的优先级计算公式中的参数y的取值方式相同:当PUSCH上承载非周期的用于LTM的CSI报告时,y=0;当PUSCH上承载半持续的用于LTM的CSI报告时,y=1;当PUCCH上承载半持续的用于LTM的CSI报告时,y=2;当PUCCH上承载周期的用于LTM的CSI报告时,y=3。其中,参数k的取值方式与CSI报告关联的优先级计算公式中的参数k的取值方式相同:当用于LTM的CSI报告携带RSRP或者SINR时,k=0;当用于LTM的CSI报告未携带RSRP或者SINR时,k=1。其中,参数c’可用于指示配置用于LTM的CSI报告的候选小区,参数s’可用于标识终端设备200发送的用于LTM的CSI报告的报告配置的参数集合,参数Ms’是用于LTM的CSI报告的报告配置的最大个数。
(一)实施例一
在一些实施例中,参数Ncells’的取值方式与CSI报告关联的优先级计算公式中的参数Ncells的取值方式相同,该参数Ncells’是通过高层信令配置的,例如Ncells’可以等于高层配置参数maxNrofServingCells的值。参数s’的取值方式与CSI报告关联的优先级计算公式中的参数s的取值方式相同。参数Ms’的取值方式与CSI报告关联的优先级计算公式中的参数Ms的取值方式相同,该参数Ms’是通过高层信令配置的,例如Ms’可以等于高层配置参数maxNrofLTMCSI-ReportConfigurations的值,该高层配置参数maxNrofLTMCSI-ReportConfigurations可用于指示用于LTM的CSI报告的报告配置的最大个数。其中,该用于LTM的CSI报告的报告配置与CSI报告的报告配置的基本配置信息相同,只是相应参数的名称不同,例如,用于LTM的CSI报告的报告配置中的ltm-CSI-ReportConfigId-r18参数对应CSI报告的报告配置中的reportConfigId参数。
在一些实施例中,在确定了参数y、参数k、参数Ncells’、参数s’、参数Ms’的情况下,参数c’可以是用于LTM的CSI报告关联的下行参考信号所在任一候选小区的索引。示例性地,参数c’可以是用于LTM的CSI报告关联的下行参考信号所在候选小区的最小索引,如图3所示,参数c’可以取最小的候选小区索引值1。参数c’还可以是用于LTM的CSI报告关联的下行参考信号所在候选小区的最大索引,如图3所示,参数c’可以取最大的候选小区索引值n。
多无线接入技术双连接(Multi-RAT Dual Connectivity,MR-DC)是指一个配置有多Rx/Tx的UE在RRC_CONNECTED状态时可以利用2个基站调度的无线资源。其中,一个基站作为主基站(master node,MN),MN可以为核心网络提供控制平面连接;另一个作为辅基站(secondary node,SN),SN可以为UE提供额外的无线资源。
本申请实施例中,在MR-DC场景下,候选主小区组(Master Cell Group,MCG)是一组与MN相关联的候选小区,MCG可以包括主小区和可选的一个或多个辅小区。在MR-DC场景下,候选辅小区组(Secondary Cell Group,SCG)是一组与SN相关联的候选小区,SCG可以包括特殊小区(SpCell)和可选的一个或多个辅小区。
本申请实施例中,在MR-DC场景下,通过为终端设备200配置多个SCG,终端设备200可以根据网络设备300的指示或预配置的判决条件,进行连续的SCG变更,由于不需要重新进行配置,可以降低信令的开销以及SCG变更的中断时间。
在一些实施例中,在确定了参数y、参数k、参数Ncells’、参数s’、参数Ms’的情况下,参数c’可以是一个固定值。示例性地,候选主小区组内参数c’可以为0;或者,候选辅小区组内参数c’可以为特殊小区(SpCell)的索引。
在一些实施例中,在确定了参数y、参数k、参数Ncells’、参数s’、参数Ms’的情况下,参数c’可以与用于LTM的CSI报告是否配置了第一配置参数(例如spCellInclusion参数)有关,该第一配置参数可用于指示终端设备200是否包括与当前特殊小区(SpCell)相关联的用于LTM的CSI报告,且只有当前特殊小区(SpCell)被配置为用于LTM的CSI报告的候选小区时,才能配置该第一配置参数。具体地,如果用于LTM的CSI报告配置了第一配置参数,例如spCellInclusion参数,则候选主小区组内参数c’可以为0;或者,候选辅小区组内参数c’可以为特殊小区(SpCell)的索引。如果用于LTM的CSI报告未配置第一配置参数,例如spCellInclusion参数,则参数c’可以是用于LTM的CSI报告关联的下行参考信号所在任一候选小区的索引。示例性地,参数c’可以是用于LTM的CSI报告关联的下行参考信号所在候选小区的最小索引,如图3所示,参数c’可以取最小的候选小区索引值1。参数c’还可以是用于LTM的CSI报告关联的下行参考信号所在候选小区的最大索引,如图3所示,参数c’可以取最大的候选小区索引值n。
(二)实施例二
进一步地,用于LTM的CSI报告与非用于LTM的CSI报告可能会重叠出现,例如,用于LTM的CSI报告与非用于LTM的CSI报告在同一个PUCCH上复用。在这种情况下,用于LTM的CSI报告关联的优先级的确定方法与非用于LTM的CSI报告关联的优先级的确定方法不统一,只能分别确定单一场景下(例如只存在用于LTM的CSI报告的场景或者只存在非用于LTM的CSI报告的场景)用于LTM的CSI报告与非用于LTM的CSI报告的优先级。因此,需要统一用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级的确定方法,并区分用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级。可选地,可以使得用于LTM的CSI报告关联的优先级高于非用于LTM的CSI报告关联的优先级。
在一些实施例中,可以重新确定参数c’、参数c、参数Ncells’以及参数Ncells来统一用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级的确定方法,并区分用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级。
具体地,重新确定参数c’,重新确定之后的参数c’可以为0或者特殊小区(SpCell)的索引。其中,特殊小区(SpCell)的索引是候选小区中的最小索引。
具体地,重新确定参数c,重新确定之后的参数c可以为终端设备200所在服务小区的索引值+1。
具体地,重新确定参数Ncells’,重新确定之后的参数Ncells’可以为重新确定之前的参数Ncells’的值+1。其中,重新确定之前的参数Ncells’是通过高层信令配置的,例如重新确定之前的Ncells’可以等于高层配置参数maxNrofServingCells的值。
具体地,重新确定参数Ncells,重新确定之后的参数Ncells可以为重新确定之前的参数Ncells的值+1。其中,重新确定之前的参数Ncells是通过高层信令配置的,例如重新确定之前的Ncells可以等于高层配置参数maxNrofServingCells的值。
例如,终端设备200配置了4个候选小区,这4个候选小区的索引值从小到大分别为0,1,2,3。当计算用于LTM的CSI报告关联的优先级时,参数c’为0。当计算非用于LTM的CSI报告关联的优先级时:若服务小区的索引值为0,则参数c为1;若服务小区的索引值为1,则参数c为2;若服务小区的索引值为2,则参数c为3;若服务小区的索引值为3,则参数c为4。因为计算非用于LTM的CSI报告关联的优先级时参数c可以为4,而重新确定之前的参数Ncells’为4,则重新确定之后的参数Ncells’应为5。
在另一些实施例中,可以重新确定参数s、参数Ms’以及参数Ms来统一用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级的确定方法,并区分用于LTM的CSI报告关联的优先级与非用于LTM的CSI报告关联的优先级。
具体地,重新确定参数s,重新确定之后的参数s可以为重新确定之前的参数s的值+重新确定之前的参数Ms’的值,以使得参数s’小于参数s。其中,重新确定之前的参数Ms’可以是通过高层信令配置的,例如重新确定之前的Ms’可以等于高层配置参数maxNrofLTMCSI-ReportConfigurations的值,该高层配置参数maxNrofLTMCSI-ReportConfigurations可用于指示用于LTM的CSI报告的报告配置的最大个数。
具体地,重新确定参数Ms’,重新确定之后的参数Ms’可以为重新确定之前的参数Ms’的值+重新确定之前的参数Ms的值。其中,重新确定之前的参数Ms’可以是通过高层信令配置的,例如重新确定之前的Ms’可以等于高层配置参数maxNrofLTMCSI-ReportConfigurations的值。重新确定之前的参数Ms可以是通过高层信令配置的,例如重新确定之前的Ms可以等于高层配置参数maxNrofCSI-ReportConfigurations的值。
具体地,重新确定参数Ms,重新确定之后的参数Ms可以为重新确定之前的参数Ms’的值+重新确定之前的参数Ms的值。其中,重新确定之前的参数Ms’可以是通过高层信令配置的,例如重新确定之前的Ms’可以等于高层配置参数maxNrofLTMCSI-ReportConfigurations的值。重新确定之前的参数Ms可以是通过高层信令配置的,例如重新确定之前的Ms可以等于高层配置参数maxNrofCSI-ReportConfigurations的值。
例如,用于LTM的CSI报告的报告配置个数为2,用于LTM的CSI报告的报告配置索引分别为0和1。非用于LTM的CSI报告的报告配置个数为3,非用于LTM的CSI报告的报告配置索引分别为0,1,2。当计算用于LTM的CSI报告关联的优先级时,参数s’可以为0或1,参数Ms’为5。当计算非用于LTM的CSI报告关联的优先级时,参数s可以为2/3/4,参数Ms为5。
