Description

一种资源限制指示方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种资源限制指示方法、装置及存储介质。
背景技术
在新无线技术(New Radio，NR)中，例如通信频段在频段2(frequency range 2)时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。
相关技术中，为了提高通信服务质量，需要进行资源限制指示，例如，需要进行码本子集限制(codebook subset restriction，CBSR)，和/或进行幅度子集限制。其中，码本子集限制是用于告知终端哪些码本不能使用，即哪些波束不能使用，因为可能会给邻小区带来干扰。幅度子集限制与码本子集限制的作用类似，比如某个波束虽然没限制完全不能使用，但是限制了这个波束上的幅度最大值，即避免了较大的干扰。
上述资源限制指示方式主要针对一个传输接收点(Transmission Reception Point，TRP)的通信传输。然而，为了改善边缘覆盖，为服务区内各用户提供均衡的服务质量，当网络设备(例如基站)有多个传输接收点(Transmission Reception Point，TRP)时，可以使用多个TRP(Muplti-TRP，mTRP)/多面板(PANEL)为终端提供服务。其中，如果网络设备配置一个信道测量资源(Channel Measurement Resource，CMR)包含N个信道状态信息参考信号(channel state information reference signal，CSI-RS)资源，则表示网络设备指示了N个TRP。其中，N为正整数。
当为终端配置了一个CMR，包含N个CSI-RS时，对N个CSI-RS的资源限制指示方式如何配置，是需要解决的问题。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
本公开实施例的资源限制指示方法可以应用于图1所示的无线通信***中。参阅图1所示，该无线通信***中包括网络设备和终端。终端通过无线资源与网络设备相连接，并 进行数据传输。
可以理解的是，图1所示的无线通信***仅是进行示意性说明，无线通信***中还可以包括其他网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信***中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信***，是一种提供无线通信功能的网络。无线通信***可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR***中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信***时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、客户前置设备(Customer Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信***时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
相关技术中，为了提高通信服务质量，需要进行资源限制指示，例如，需要进行码本 子集限制(codebook subset restriction，CBSR)，和/或进行幅度子集限制。其中，码本子集限制是用于告知终端哪些码本不能使用，即哪些波束不能使用，因为可能会给邻小区带来干扰。幅度子集限制与码本子集限制的作用类似，比如某个波束虽然没限制完全不能使用，但是限制了这个波束上的幅度最大值，即避免了较大的干扰。
同时，为了在服务区内提供更为均衡的服务质量，引入多点协作传输(Coordinated Multiple Point transmission，CoMP)技术。
多点协作传输技术大致可分为相干传输(Coherent Joint Transmission，CJT)和非相干传输(Non-Coherent Joint Transmission，NCJT)两种。所谓CJT是指每个数据流会通过加权向量映射到参与协作的m-TRP/Panel上。CJT相当于将多个子阵拼接成为一个更高维度的虚拟阵列，以获得更高的赋形或预编码增益。
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)工作组正在讨论基站使用最多4个TRP为终端提供物理下行共享信道PDSCH的CJT服务，目前已经同意如果基站配置了一个CMR包含N个CSI-RS资源，即表示基站指示了N个TRP。
其中，每个CSI-RS对应的端口数是一样的。每个CSI-RS可配置的端口数可以如表1所示：
表1
Figure PCTCN2022141694-appb-000001
其中，P CSI-RS为CSI-RS对应的端口数，N 1代表第一维度天线端口数，N 2代表第二维度天线端口数，O 1代表第一维度过采样率，O 2代表第二维度过采样率。
传统情况下，考虑一个TRP传输时，Rel-16 Type II码本(codebook)和Rel-17端口 选择码本的码本限制如下：
Figure PCTCN2022141694-appb-000002
Figure PCTCN2022141694-appb-000003
Figure PCTCN2022141694-appb-000004
其中，SEQUENCE代表码本序列，codebookSubsetRestriction代表码本子集限制，BITSTRING代表比特序列，CodebookConfig代表码本配置参数，codebookType代表码本类型，typeI-SinglePanel代表单面板类型I，nrOfAntennaPorts代表CSI-RS的端口数量。上述码本限制指示了单面板为终端提供服务时，针对CSI-RS具有不同端口数的情况，可以配置具有不同大小的码本子集限制比特序列。
当为终端配置了一个CMR，包含N个CSI-RS时，对N个CSI-RS的资源限制指示方式如何配置，是需要解决的问题。
鉴于此，本公开提供了一种资源限制指示方法，根据终端接收的第一配置信息配置包括N个信道状态信息参考信号CSI-RS资源的至少一个信道测量资源，并根据终端接收的第二配置信息来获取对上述N个CSI-RS资源对应的资源限制指示，针对诸如网络设备为终端配置的一个CMR中包含N个CSI-RS等网络设备使用多个TRP为终端提供服务的场景，提出了针对多个CSI-RS资源的资源限制指示，提高了PDSCH的CJT能力。
图2是根据一示例性实施例示出的一种资源限制指示方法的流程图，该资源限制指示方法用于终端中，如图2所示，该资源限制指示方法包括以下步骤。
在步骤S21中，接收第一配置信息，第一配置信息用于配置至少一个信道测量资源，至少一个信道测量资源中包括N个信道状态信息参考信号CSI-RS资源。
其中，N为正整数。
在步骤S22中，接收第二配置信息，第二配置信息用于指示N个CSI-RS资源对应的 资源限制指示。
本公开实施例中，终端接收第一配置信息，第一配置信息可以用于配置至少一个CMR，至少一个CMR中可以包括N个信道状态信息参考信号CSI-RS资源。一示例中，可以是上述至少一个CMR中的每一个CMR包括N个CSI-RS资源，其中，N为正整数。
本公开实施例中，终端还接收第二配置信息，第二配置信息可用于指示N个CSI-RS资源对应的资源限制指示。其中，资源限制指示可以包括以下中的至少一项：码本子集限制(Codebook Subset Restriction，CBSR)指示，幅度子集限制指示，秩(RANK)限制指示。
采用本公开实施例的技术方案，针对诸如网络设备为终端配置的一个CMR中包含N个CSI-RS等网络设备使用多个TRP为终端提供服务的场景，提出了针对多个CSI-RS资源的，包括CBSR指示、幅度子集限制指示和/或秩限制指示在内的资源限制指示，提高了PDSCH的CJT能力。
本公开实施例中，资源限制指示可以包括CBSR指示。其中，CBSR指示可以通过CBSR指示比特序列进行配置。此时，第二配置信息可以包括CBSR指示比特序列。
其中，CBSR指示比特序列用于配置N个CSI-RS资源对应的CBSR指示。
其中，N个CSI-RS资源可以对应一个或N个CBSR指示。CBSR指示比特序列对应的比特位图(bitmap)中可以包括多个比特位，每个比特位对应一个码本子集指示，以用于指示各个码本子集是否被限制。
图3是根据一示例性实施例示出的一种CBSR指示方法的流程图，如图3所示，该CBSR指示方法包括以下步骤。
在步骤S31中，响应于CBSR指示比特序列包括单一的CBSR指示比特序列，配置单一的CBSR指示比特序列用于指示N个CSI-RS资源对应相同的CBSR指示。
本公开实施例中，CBSR指示比特序列可以包括单一的CBSR指示比特序列，该单一的CBSR指示比特序列用于指示N个CSI-RS资源对应相同的CBSR指示。也可以理解为，N个CSI-RS对应的CBSR相同：使用一个CBSR指示比特序列来配置N个CSI-RS对应的CBSR。
一示例中，若网络设备为终端配置了一个CMR，该CMR包括N个CSI-RS资源时，可以使用一个CBSR指示比特序列，来指示上述N个CSI-RS资源对应的CBSR指示。此时，N个CSI-RS资源对应的CBSR指示比特序列相同。也可以理解为，N个CSI-RS的CBSR都对应该一个CBSR指示比特序列来指示，即N个CSI-RS的CBSR的比特序列相同。也就是说，对于N个CSI-RS资源，被限制的码本子集是一样的。
其中，本公开实施例中，由于每个CSI-RS的端口数均不会超过32，因此采用这种利用单一的CBSR指示比特序列指示N个CSI-RS资源对应相同的CBSR指示的方式设置的CBSR指示比特序列，比特序列的大小可以复用传统的比特序列大小。其中，传统的比特序列大小可以是前述Rel-16 Type II码本和Rel-17端口选择码本的码本子集限制指示所使用的比特序列大小，针对CSI-RS具有不同端口数的情况，可以选择不同大小的CBSR指示比特序列。
图4是根据一示例性实施例示出的一种CBSR指示方法的流程图，如图4所示，该CBSR指示方法包括以下步骤。
在步骤S41中，响应于CBSR指示比特序列包括单一的CBSR指示比特序列，配置单一的CBSR指示比特序列中包括N个子比特序列，N个子比特序列用于分别指示N个CSI-RS资源对应的CBSR指示。
本公开实施例中，CBSR指示比特序列可以包括单一的CBSR指示比特序列，该单一的CBSR指示比特序列中可以包括N个子比特序列，N个子比特序列用于分别指示N个CSI-RS资源对应的码本子集限制指示。也可以理解为，N个CSI-RS对应的CBSR独立配置，使用一个CBSR指示比特序列中的不同比特来配置N个CSI-RS对应的CBSR，N个CSI-RS中每个CSI-RS的CBSR对应该一个CBSR指示比特序列中的一部分比特。
一示例中，若网络设备为终端配置了一个CMR，该CMR包括N个CSI-RS资源时，可以使用一个CBSR指示比特序列，来指示上述N个CSI-RS资源对应的CBSR指示。其中，该一个CBSR指示比特序列可以包括N个子比特序列，例如CBSR指示子比特序列#0、CBSR指示子比特序列#1……CBSR指示子比特序列#(N-1)。此时，可以通过上述CBSR指示子比特序列#0、CBSR指示子比特序列#1……CBSR指示子比特序列#(N-1)分别指示N个CSI-RS资源对应的CBSR指示。其中，每个CBSR指示子比特序列对应一个CSI-RS资源对应的CBSR指示，且N个CSI-RS资源对应的CBSR指示所对应的比特数量相同，也就是说，上述N个CBSR指示子比特序列中，每个CBSR指示子比特序列具有相同的比特数量。进一步的，上述N个CBSR指示子比特序列中，每个CBSR指示子比特序列可以是该一个CBSR指示比特序列中连续的一部分比特，或者是该一个CBSR指示比特序列中不连续的一部分比特。也就是说，对于N个CSI-RS资源，被限制的码本子集是独立配置的，N个CSI-RS资源被限制的码本子集可以一样或不一样。
采用这种利用单一的CBSR指示比特序列中不同比特来分别指示N个CSI-RS资源对应的CBSR指示的方式设置的CBSR指示比特序列，当N个CSI-RS的端口数之和大于32时，将无法复用传统的CBSR指示比特序列的大小，此时需要重新确定新的比特序列长度。 在重新确定新的比特序列长度时，每个CSI-RS资源对应的CBSR指示比特序列可以相同或不同。其中，传统的比特序列大小可以是前述Rel-16 Type II码本和Rel-17端口选择码本的码本子集限制指示中所使用的比特序列大小，针对CSI-RS具有不同端口数的情况，可以选择不同大小的CBSR指示比特序列。
图5是根据一示例性实施例示出的一种CBSR指示方法的流程图，如图5所示，该CBSR指示方法包括以下步骤。
在步骤S51中，响应于CBSR指示比特序列包括N个CBSR指示比特序列，配置N个CBSR指示比特序列用于分别指示N个CSI-RS资源对应的CBSR指示。
本公开实施例中，CBSR指示比特序列可以包括N个CBSR指示比特序列，N个CBSR指示比特序列用于分别指示N个CSI-RS资源对应的CBSR指示。也可以理解为，N个CSI-RS对应的CBSR独立配置，使用N个CBSR指示比特序列来分别配置N个CSI-RS对应的CBSR，N个CSI-RS中每个CSI-RS的CBSR对应一个CBSR指示比特序列。
一示例中，若网络设备为终端配置了一个CMR，该CMR包括N个CSI-RS资源时，可以使用N个CBSR指示比特序列来指示上述N个CSI-RS资源对应的CBSR指示。例如使用CBSR指示比特序列#0、CBSR指示比特序列#1……CBSR指示比特序列#(N-1)分别指示N个CSI-RS资源对应的CBSR指示。其中，每个CBSR指示比特序列对应一个CSI-RS资源对应的CBSR指示，且N个CSI-RS资源对应的CBSR指示所对应的比特数量相同，也就是说，上述N个CBSR指示比特序列中，每个CBSR指示比特序列具有相同的比特数量。进一步的，N个CSI-RS资源与N个CBSR指示比特序列之间具有一一对应关系，也就是，每一个CBSR指示比特序列对应一个CSI-RS资源。也就是说，对于N个CSI-RS资源，被限制的码本子集是独立配置的，N个CSI-RS资源被限制的码本子集可以一样或不一样。
采用这种利用N个CBSR指示比特序列分别指示N个CSI-RS资源对应的CBSR指示的方式设置的CBSR指示比特序列，每个比特序列的大小可以复用传统的比特序列大小。其中，传统的比特序列大小可以是前述Rel-16 Type II码本和Rel-17端口选择码本的码本子集限制指示中所使用的比特序列大小，针对CSI-RS具有不同端口数的情况，可以选择不同大小的CBSR指示比特序列。
本公开实施例中，第二配置信息可以承载在无线资源控制(Radio Resource Control，RRC)信令和/或媒体接入控制控制(Medium Access Control Control Element，MAC CE)单元信令中。
采用本公开实施例的技术方案，针对诸如网络设备为终端配置的一个CMR中包含N 个CSI-RS等网络设备使用多个TRP为终端提供服务的场景，提出了针对多个CSI-RS资源的通用配置或者独立配置的CBSR指示，进一步提高了PDSCH的CJT能力。
本公开实施例中，资源限制指示可以包括幅度子集限制指示。其中，幅度子集限制可以通过第一指示信息进行配置。此时，第二配置信息可以包括第一指示信息。
其中，第一指示信息用于指示N个CSI-RS资源对应支持或不支持的幅度系数信息。
其中，N个CSI-RS资源可以对应一个或N个幅度子集限制指示。N个幅度子集限制指示可以由N个第一指示信息来指示，也可以由一个第一指示信息中包含的N个比特来指示。
图6是根据一示例性实施例示出的一种幅度子集限制指示方法的流程图，如图6所示，该幅度子集限制指示方法包括以下步骤。
在步骤S61中，响应于第二配置信息包括单一的第一指示信息，配置单一的第一指示信息用于指示N个CSI-RS资源对应相同的幅度子集限制指示。
本公开实施例中，第二配置信息可以包括单一的第一指示信息，单一的第一指示信息用于指示N个CSI-RS资源对应相同的幅度子集限制指示。也可以理解为，使用一个第一指示信息来配置N个CSI-RS资源对应的幅度子集限制指示，N个CSI-RS资源对应的幅度子集限制指示相同。
一示例中，若网络设备为终端配置了一个CMR，该CMR包括N个CSI-RS资源时，可以使用一个第一指示信息来指示上述N个CSI-RS资源对应的幅度子集限制指示。此时，N个CSI-RS资源对应的幅度子集限制指示相同，也就是说，若第一指示信息指示为支持，则N个CSI-RS资源均支持幅度子集限制，若第一指示信息指示为不支持，则N个CSI-RS资源均不支持幅度子集限制。
图7是根据一示例性实施例示出的一种幅度子集限制指示方法的流程图，如图7所示，该幅度子集限制指示方法包括以下步骤。
在步骤S71中，响应于第二配置信息包括单一的第一指示信息，配置单一的第一指示信息包括N个比特，通过该N个比特分别指示N个CSI-RS资源对应的幅度子集限制指示。
本公开实施例中，第二配置信息可以包括单一的第一指示信息，单一的第一指示信息可以包括N个比特，通过该N个比特分别指示N个CSI-RS资源对应的幅度子集限制指示。也可以理解为，N个CSI-RS资源对应的幅度子集限制指示独立配置。使用一个第一指示信息来配置N个CSI-RS资源分别对应的幅度子集限制指示，该一个第一指示信息可以是为一个比特序列，该比特序列至少包括N个比特，使用该比特序列中的N个比特分别配置N个CSI-RS资源对应的幅度子集限制指示，每个CSI-RS资源对应该比特序列中的1比特。
一示例中，若网络设备为终端配置了一个CMR，该CMR包括N个CSI-RS资源时，可以使用一个至少包括N个比特的第一指示信息中的N个比特，例如第一指示信息中的bit0、bit1……bit(N-1)这N个比特分别指示N个CSI-RS资源对应的幅度子集限制指示。也就是说，不同的CSI-RS资源对应的幅度子集限制独立配置，不同的CSI-RS资源对应的幅度子集限制可以一样或不一样。

一示例中，若网络设备为终端配置了一个CMR，该CMR包括N个CSI-RS资源时，可以使用一个第二指示信息来指示上述N个CSI-RS资源对应的秩限制指示。此时，N个CSI-RS资源对应的秩限制指示相同，也就是说，若第一指示信息指示为支持秩为1和2，则N个CSI-RS资源均支持的秩仅包括1和2；若第一指示信息指示支持秩为1，2，3和4，则N个CSI-RS资源均支持秩为1，2，3和4。

一示例中，若网络设备为终端配置了一个CMR，该CMR包括N个CSI-RS资源时，可以使用N个第二指示信息分别指示N个CSI-RS资源对应的秩限制指示。例如使用第二指示信息#0、第二指示信息#1……第二指示信息#(N-1)分别指示N个CSI-RS资源对应的秩限制指示。每个第二指示信息包含一个比特序列。

采用本公开实施例的技术方案，针对诸如网络设备为终端配置的一个CMR中包含N个CSI-RS等网络设备使用多个TRP为终端提供服务的场景，提出了针对多个CSI-RS资源的，包括CBSR指示、幅度子集限制指示和/或秩限制指示在内的资源限制指示，提高了PDSCH的CJT能力。

其中，本公开实施例中，由于每个CSI-RS的端口数均不会超过32，因此采用这种利用单一的CBSR指示比特序列指示N个CSI-RS资源对应相同的CBSR指示的方式设置的CBSR指示比特序列，比特序列的大小可以复用传统的比特序列大小。其中，传统的比特序列大小可以是前述Rel-16 Type II码本和Rel-17端口选择码本的码本子集限制指示所使用的比特序列大小，针对CSI-RS具有不同端口数的情况，可以选择不同大小的CBSR指示比特序列。
本公开实施例中，CBSR指示比特序列可以包括单一的CBSR指示比特序列，该单一的CBSR指示比特序列中可以包括N个子比特序列，N个子比特序列用于分别指示N个CSI-RS资源对应的码本子集限制指示。也可以理解为，N个CSI-RS对应的CBSR独立配置，使用一个CBSR指示比特序列中的不同比特来配置N个CSI-RS对应的CBSR，N个CSI-RS中每个CSI-RS的CBSR对应该一个CBSR指示比特序列中的一部分比特。

采用这种利用单一的CBSR指示比特序列中不同比特来分别指示N个CSI-RS资源对应的CBSR指示的方式设置的CBSR指示比特序列，当N个CSI-RS的端口数之和大于32时，将无法复用传统的CBSR指示比特序列的大小，此时需要重新确定新的比特序列长度。在重新确定新的比特序列长度时，每个CSI-RS资源对应的CBSR指示比特序列可以相同或不同。其中，传统的比特序列大小可以是前述Rel-16 Type II码本和Rel-17端口选择码本的码本子集限制指示中所使用的比特序列大小，针对CSI-RS具有不同端口数的情况，可以选择不同大小的CBSR指示比特序列。
