通过以上方法,本公开实施例可以在接收到的CSI配置信息中的CSI报告开始占用的信道状态信息处理单元的总数目大于在同一符号中未被占用的信道状态信息处理单元的 数目的情况下,根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告,从而适应多TRP场景,对多TRP场景下的CSI进行处理,从而使得各个TRP可以适应信道条件,确保通信的可靠性。
应该说明的是,本公开实施例除了可以应用在多TRP场景(包括2个以上的TRP),还可以应用于单个TRP场景下。
所述“CSI配置信息中的CSI报告”可以表示需要用户设备计算并生成的CSI报告。
在一种可能的实施方式中,所述CSI配置信息包含的多发送接收点的CSI配置信息可以为多发送接收点TRP传输假设下的CSI配置信息。
在一种可能的实施方式中,每个TRP可以通过高层信息(例如RRC信息等)发送CSI配置信息,和/或者下行控制信息DCI触发CSI计算反馈,对于TRP发送CSI配置信息的方式,本公开实施例不做限定。
在一个示例中,当用户设备接收到CSI配置信息,可以根据CSI配置信息确定网络配置的CSI报告相关的信息,并根据相关通信协议和配置计算CSI报告需要占用的CSI处理单元(即开始占用的CSI处理单元)。当然,本公开实施例对如何计算CSI报告开始占用的CSI处理单元的数目的具体实施方式不做限定。
在一种可能的实施方式中,信道状态信息处理单元可以用于根据CSI配置信息计算信道质量等参数,从而获得CSI报告。
在一种可能的实施方式中,用户设备可以提前将可以支持的最大并行计算的CSI处理单元的数目发送到TRP,这样,TRP可以获知用户设备的CSI处理单元的数目。
在一种可能的实施方式中,步骤S12中的“同一符号”可以为同一正交频分复用OFDM符号,“同一符号”可以表示一次网络传输。
当然,在其他实施方式中,也可以是不同符号。
本公开实施例中,步骤S12根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告可以包括多种实施方式,下面进行示例性介绍。
请参阅图3,图3示出了根据本公开一实施方式的信道状态信息CSI处理方法的流程图。
在一种可能的实施方式中,如图3所示,步骤S12根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告,可以包括:
步骤S121,以第一方式处理所述CSI配置信息对应的一个或多个CSI报告,在所述第一方式中,1个CSI报告携带一个或多个发送接收点的CSI信息;或者
步骤S122,以第二方式处理所述CSI配置信息对应的一个或多个CSI报告,在所述第二方式中,1个CSI报告仅携带1个发送接收点的CSI信息。
通过以上方法,本公开可以根据不同的处理方式处理一个或多个CSI报告,从而增加灵活性和环境适应性。
在一个示例中,第一方式、第二方式可以提前配置,本领域技术人员可以根据需要配置和实际场景第一方式或第二方式。
在一个示例中,网络可以配置用户设备第一方式处理所述CSI配置信息对应的一个或多个CSI报告,假设通信系统包括3个TRP,则网络可以配置终端利用1个CSI报告发送1个或2个或3个TRP的CSI信息。
在一个示例中,以第一方式处理所述CSI配置信息对应的一个或多个CSI报告,可以包括用户设备根据所述CSI配置信息分别得到多个CSI信息,并将多个CSI信息生成一个CSI报告,并将一个CSI报告发送。
在一个示例中,网络可以配置用户设备以第二方式处理所述CSI配置信息对应的一个或多个CSI报告,假设通信系统包括3个TRP,则网络可以配置终端利用3个CSI报告分别报告3个TRP的CSI信息。
在一个示例中,以第二方式处理所述CSI配置信息对应的一个或多个CSI报告,可以 包括,用户设备根据所述CSI配置信息分别得到多个CSI信息,并将所述多个CSI信息作为独立的CSI报告发送。
在一个示例中,无论是以第一方式、第二方式处理所述CSI配置信息对应的一个或多个CSI报告,用户设备在得到一个或多个CSI报告后,可以选择将一个或多个CSI报告发送到某一个TRP,也可以将一个或多个CSI报告发送到多个TRP,对此,本公开实施例不做限定。
当用户设备被配置为通过第一方式处理所述CSI配置信息对应的一个或多个CSI报告的情况下,步骤S12根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告,可以包括:
在CSI报告对应的一个或多个发送接收点中任意一个发送接收点的CSI报告开始占用的信道状态信息处理单元大于所述未被占用的信道状态信息处理单元的数目,则不更新CSI报告。
在一个示例中,若多个TRP中任意一个TRP的CSI报告开始占用的信道状态信息处理单元大于未被占用的CSI处理单元,由于用户设备的未被占用的CSI处理单元的数目无法完成任意一个TRP的CSI报告的计算和生成,因此,用户设备可以不更新CSI报告,从而适应当前的运算环境,以提高灵活性和环境适应性。
在一种可能的实施方式中,步骤S121以第一方式处理所述CSI配置信息对应的一个或多个CSI报告的情况下,所述根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告,可以包括:
若N个发送接收点的CSI报告开始占用的信道状态信息处理单元的总数目小于或等于所述未被占用的信道状态信息处理单元的数目,则更新第一CSI报告,所述第一CSI报告包含所述N个发送接收点的CSI信息,其中,1≤N<M、且为整数,M表示发送接收点的总数。
在一个示例中,可以在确定M个TRP的CSI报告开始占用的信道状态信息处理单元大于在同一符号中未被占用的信道状态信息处理单元的数目的情况下,确定是否存在N个TRP的CSI报告开始占用的CSI处理单元的总数目小于或等于未被占用的CSI处理单元,其中,M表示配置的发送接收点的总数。
当M个TRP中存在N个TRP的CSI报告开始占用的CSI处理单元的总数目小于或等于用户设备中未被占用的CSI处理单元的数目时,用户设备可以确定,当前的未被占用的CSI处理单元有能力计算并生成N个TRP的CSI报告(第一CSI报告),因此,用户设备启动更新流程,以更新第一CSI报告。
在一个示例中,更新第一CSI报告可以包括利用未被占用的CSI处理单元根据CSI配置信息计算N个TRP的CSI信息,在得到N个TRP的CSI信息的情况下,生成第一CSI报告,并发送第一CSI报告。
本公开实施例可以有多种实现方式确定第一CSI报告关联的N个TRP,即,可以通过多种方式确定在第一CSI报告发送的相关的N个TRP,下面进行示例性介绍。
在一种可能的实施方式中,所述CSI配置信息可以包括用于信道测量的参考信号资源CSI-RS,和/或,用于干扰测量的干扰测量资源。
在一个示例中,用户设备可以根据CSI-RS计算并生成CSI报告,从而确定当前信道的信道质量等参数,也可以根据干扰测量资源计算并生成CSI报告,以确定其他TRP对当前TRP的干扰程度等信息,或者根据CSI-RS和干扰测量资源计算并生成CSI报告,对此,本公开不做限定。
当然,以上描述是示例性,在其他的实施方式中,CSI配置信息还可以包括其他测量资源,以完成其他测量项目,对此,本公开不做限定。
在一种可能的实施方式中,所述第一CSI报告中的N个发送接收点的CSI信息可以对 应于M个发送接收点的CSI配置信息中参考信号资源和/或干扰测量资源出现最早的N个发送接收点的CSI信息。
在一个示例中,用户设备可以根据参考信号资源或干扰测量资源的出现时间确定与第一CSI报告中上报的CSI信息相关的N个TRP,当M个发送接收点的前N个发送接收点对应的CSI-RS或干扰测量资源出现时间最早,且该前N个发送接收点的CSI报告开始占用的CSI处理单元的总数目小于或等于未被占用的CSI处理单元的数目的情况下,可以对所述前N个发送接收点的CSI报告进行处理,从而得到所述第一CSI报告。
在一种可能的实施方式中,所述第一CSI报告中的N个发送接收点的CSI信息可以对应于M个发送接收点的CSI配置信息中的参考信号资源的标识和/或干扰测量资源的标识最小的N个发送接收点的CSI信息。
在一个示例中,参考信号资源的标识可以包括参考信号资源的编号,干扰测量资源的标识可以包括干扰测量资源的编号,编号的大小可以用于表示对应的CSI信息被处理的优先级的高低,例如,编号越小可以视为优先级越高,即编号越小的测量资源对应的CSI信息可以被优先处理。
在一个示例中,用户设备可以根据所述CSI配置信息确定每个TRP的CSI报告关联的CSI-RS的标识和/或干扰测量资源的标识,并确定前N个标识(编号最小)的TRP,在该N个TRP的CSI报告开始占用的CSI信息处理单元的总数小于或等于未被占用的CSI处理单元的数目的情况下,可以对标识为前N的TRP的CSI报告进行处理,从而得到所述第一CSI报告。
以上介绍了第一方式处理所述CSI配置信息对应的一个或多个CSI报告的情况,下面对以第二方式处理所述CSI配置信息对应的一个或多个CSI报告的情况将进行示例性介绍。
在一种可能的实施方式中,步骤S122以第二方式处理所述CSI配置信息对应的一个或多个CSI报告的情况下,所述根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告,可以包括:
在多发送接收点的P个CSI报告开始占用的信道状态信息处理单元的总数目大于所述未被占用的信道状态信息处理单元的数目的情况下,不更新所述P个CSI报告,其中,1≤P≤发送接收点的总数、且P为整数。
在一个示例中,当P个TRP的CSI报告开始占用的信道状态信息处理单元的总数目大于未被占用的CSI处理单元的数目的情况下,说明用户设备的剩余可用的CSI处理单元无法实现对P个TRP的CSI报告的计算和生成,因此,用户设备可以选择不更新P个TRP的P个CSI报告,以适应当前用户设备的应用环境,从而提供灵活性和环境适应性。
在一种可能的实施方式中,所述不更新所述P个CSI报告,可以包括:
若一个或多个发送接收点中任意一个CSI报告开始占用的信道状态信息处理单元的数目大于所述未被占用的信道状态信息处理单元的数目,则不更新所述P个CSI报告。
在一个示例中,P可以为1,即,当多个TRP的任意一个TRP的CSI报告开始占用的CSI处理单元的数目大于未被占用的CSI处理单元的数目的情况下,说明用户设备无法完成任意一个TRP的CSI报告的计算和生成,因此,用户设备可以选择不更新所述P个CSI报告。
在一种可能的实施方式中,步骤S122以第二方式处理所述CSI配置信息对应的一个或多个CSI报告的情况下,所述根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告,还可以包括:
在多发送接收点的Q个CSI报告开始占用的信道状态信息处理单元的总数目大于所述未被占用的信道状态信息处理单元的数目的情况下,
若T个CSI报告开始占用的信道状态信息处理单元的总数目小于或等于所述未被占用的信道状态信息处理单元的数目,则更新T个第二CSI报告,其中,所述第二CSI报告包括一个对应的发送接收点的CSI信息,T<Q,1≤Q≤发送接收点的总数、且Q为整数。
在一个示例中,当多TRP中Q个TRP的CSI报告开始占用的CSI处理单元的总数大于用户设备未被占用的CSI处理单元的数目的情况下,用户设备可以在满足一定条件的情况下,更新CSI报告,从而实现对信道条件的测量。
在一个示例中,用户设备可以继续判断T个CSI报告开始占用的CSI处理单元的总数是否小于或等于未被占用的CSI处理单元的数目,当T个CSI报告开始占用的CSI处理单元的总数小于或等于未被占用的CSI处理单元的数目的情况下,用户设备可以确定当前的CSI处理单元的处理能力足够完成T个CSI报告的计算和生成,因此,用户设备可以启动T个TRP的CSI报告的计算和生成,以得到多个第二CSI报告。
在一种可能的实施方式中,所述根据所述CSI配置信息处理所述CSI配置信息对应的一个或多个CSI报告,还可以包括:
从O个CSI报告中确定T个CSI报告,其中,所述O个CSI报告中每一个CSI报告开始占用的信道状态信息处理单元的数目小于或等于所述未被占用的信道状态信息处理单元的数目,其中T≤O,O<Q。
在一个示例中,在多发送接收点的Q个CSI报告开始占用的信道状态信息处理单元的总数目大于所述未被占用的信道状态信息处理单元的数目的情况下,用户设备可以继续判断O个CSI报告开始占用的CSI处理单元的总数是否大于未被占用的CSI处理单元的数目,当O个CSI报告中每一个CSI报告开始占用的CSI处理单元都小于或等于未被占用的CSI处理单元的数目的情况下,用户设备可以从O个CSI中确定T个CSI报告。
在一种可能的实施方式中,所述CSI配置信息可以包括CSI报告的编号、用于信道测量的参考信号资源,和/或,用于干扰测量的干扰测量资源,或其他信息。
在一种可能的实施方式中,本公开实施例可以根据CSI报告的编号、用于信道测量的参考信号资源,和/或,用于干扰测量的干扰测量资源确定T个CSI报告对应于哪几个TRP(或O个CSI报告)。
在一个示例中,所述T个第二CSI报告可以对应于O个CSI报告中的CSI报告的编号最小的T个CSI报告。
在一个示例中,所述T个第二CSI报告可以对应于O个CSI报告中(的CSI报告)关联的参考信号资源和/或干扰测量资源出现最早的T个CSI报告。
当然,以上描述是示例性的,用户设备也可以直接从Q个CSI报告中确定T个CSI报告,例如,根据Q个CSI报告的编号及关联的测量资源的出现时间,从Q个CSI报告的编号靠前的CSI报告开始或从Q个CSI报告的测量资源的出现时间靠前的CSI报告开始,依次将T个CSI报告开始占用的CSI处理单元数目进行累加,若T个CSI报告开始占用的CSI处理单元的总数目小于或等于未被占用的CSI处理单元的数目,则确定该T个CSI报告,并根据CSI配置信息对该T个CSI报告进行处理,以得到多个第二CSI报告。
在一种可能的实施方式中,用户设备可以根据CSI配置信息确定CSI报告的编号及测量资源(CSI-RS、干扰测量资源等)的出现时间,从而根据CSI报告的编号或测量资源的出现时间的先后确定要处理的T个CSI报告。
在一个示例中,在确定测量资源的出现时间时,本公开实施例可以利用多个测量资源的第一个OFDM符号确定,根据第一个OFDM符号可以确定测量资源的最早出现时间,从而确定测量资出现的先后顺序。
当然,本公开实施例不限于此,在其他的实施方式中,本领域技术人员可以利用其他方式确定测量资源的出现时间。
通过以上方式,本公开实施例可以快速确定T个CSI报告。
通过以上方法,本公开实施例可以对多TRP场景下的CSI报告进行处理,当TRP发送的CSI配置信息的CSI报告开始占用的CSI处理单元的总数目大于未被占用的CSI处理单元的数目时,本公开实施例可以根据CSI配置信息处理一个或多个CSI报告,从而利用用户 设备的可用CSI处理单元实现信道测量,得到CSI报告。
