一种通信方法、装置、设备和存储介质
相关申请的交叉引用
本申请主张在2022年11月03日在中国提交的中国专利申请No.202211370285.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信领域，尤其涉及一种通信方法、装置、设备和存储介质。
背景技术
在非码本的上行传输方案中，用户设备(User Equipment，UE)可利用探测参考信号(Sounding Reference Signal，SRS)资源指示(SRS Resource Indication，SRI)确定数据的预编码和传输层数。
相关技术中，当物理上行共享信道(Physical Uplink Shared Channel，PUSCH)配置为基于非码本的传输模式时，首先需要UE发送用于基于非码本(non-codebook)的上行传输的信道探测参考信号(Sounding Reference Signal，SRS)，即SRS资源集(SRS resource set)的用法(usage)配置为非码本。对于非码本上行传输方案，基站可为UE配置最多1个SRS资源集，包含1～4个SRS资源，每个SRS资源都是单端口。
然而，随着UE传输的数据流数量的增强，沿用现有的SRS资源配置方式，会对下行控制信道带来极大的开销。

具体实施方式
相关技术中，非码本的上行传输方法如图1所示，所述方法包括：
UE基于下行信道估计确定SRS的预编码，并发送预编码的SRS；即UE测量下行参考信号，获得候选的上行预编码矩阵，利用它们对用于非码本上行传输方案的SRS进行预编码后将其发送给基站。
基站根据UE发送的SRS进行上行信道检测，对UE进行资源调度，确定出上行传输对应的SRS资源和上行传输的调制编码方案(Modulation and coding scheme，MCS)等级等，并通知UE。其中上行传输对应的SRS资源通过SRI指示给UE。
UE根据基站发送的MCS对数据进行调制编码，并利用SRI确定数据的预编码和传输层数，对数据进行预编码后进行数据的发送。非码本上行传输方案下的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)解调导频与PUSCH的数据采用相同的预编码方式。
基站根据解调导频信号估计上行信道，进行数据检测。
这里，基站通过DCI指示SRS资源指示(SRS Resource Indication，SRI)，其中，SRI可指示1个或多个SRS资源。SRI中指示的SRS资源数即为PUSCH传输的秩指示(Rank indicator，RI)，SRI中指示的SRS资源所采用的预编码就是物理上行共享信道(PhysicalUplinkSharedCHannel，PUSCH)传输的传输预编码矩阵指示(Transmitting Precoding MatrixIndicator，TPMI)，PUSCH的传输层与SRI指示的SRS资源一一对应。
表1为SRI指示用于基于非码本的PUSCH传输(SRI indication for non-codebook based PUSCH transmission)一种示例，Lmax＝2，Lmax为终端被配置的上行传输流的最大数量。

表1
其中，reserved是指保留位。
相关研究中确认对于8Tx的终端上行发送，需要4流以及大于4流的传输，最多可以增强至8流。
对于SRI非码本传输，假如对8Tx终端需要增强至8流传输，沿用现有4Tx终端最大4流传输的设计，那么需要配置1个SRS资源集(resource set)用于非码本传输，SRS资源集中包含8个SRS资源(resource)，每一个SRS资源具有1个端口。
假如最多流数Lmax＝8，那么对于1、2、3、4、5、6、7、8流传输，共有C81+C82+C83+C84+C85+C86+C87+C88＝8+28+56+70+56+28+8+1＝2^8-1＝255种可能的SRI指示组合，那么DCI中的SRI指示域最多需要占用8bit，这会对下行控制信道带来极大的开销。
基于此，本公开实施例提供的方法，网络设备向终端发送配置信息；所述配置信息用于指示用于非码本上行传输的资源集；所述资源集包括：至少一个SRS资源；所述资源集中的SRS资源具有至多X个端口，X为大于或等于1的正整数。相应地，终端接收所述网络设备发送的配置信息。

具体来说，所述指示信息可以包括：指示的至少一个SRS资源的标识或索引；相应的，配置信息指示的资源集还包括：每个SRS资源对应的唯一的标识或索引。
图3为本公开实施例提供的另一种通信方法的流程示意图；如图3所示，所述方法可以应用于终端，所述方法包括：
步骤301、接收来自网络设备的配置信息；所述配置信息用于指示用于非码本上行传输的资源集；所述资源集包括：至少一个SRS资源；所述资源集中的SRS资源具有至多X个端口，X为大于或等于1的正整数。
这里，网络设备针对终端配置用于非码本上行传输的资源集，通过配置信息指示所述资源集。终端接收配置信息，根据配置信息确定所述资源集。
在一些实施例中，所述资源集，包括：至少一个第一SRS资源；所述至少一个第一SRS资源中每个第一SRS资源具有两个或四个端口。
在一些实施例中，所述资源集，包括：至少一个第一SRS资源、至少一个第二SRS资源；
其中，所述至少一个第一SRS资源中每个第一SRS资源具有两个或四个端口；
所述至少一个第二SRS资源中每个第二SRS资源具有一个或两个端口。
在一些实施例中，所述资源集，包括：至少一个第一SRS资源、至少一个第二SRS资源、至少一个第三SRS资源；
其中，所述至少一个第一SRS资源中每个第一SRS资源具有两个端口；
所述至少一个第二SRS资源中每个第二SRS资源具有一个端口；

在一些实施例中，所述X与终端被配置的上行传输流的数量相关；所述资源集中每个SRS资源的端口数的总和大于或等于所述终端需求的天线上行传输流的数量。
在一些实施例中，所述资源集中每个SRS资源的每一个SRS端口的发送功率相同。
实际应用时，为保证基站侧可以公平的测量各个端口所对应的信道质量，需要保证每个端口的发送功率相同，也就要求每一个SRS资源的的每个端口的发送功率相同。
基于此，在一些实施例中，相应于所述资源集中每个SRS资源的端口数目相等的情况下，所述方法还包括：
基于以下至少之一确定所述资源集中每个SRS资源的发送功率：
终端的最大发送功率、开环功率控制功率、子载波因子、SRS占用资源块数目、资源集的路径损耗补偿系数、终端利用参考信号资源索引得到的路径损耗、闭环功率控制部分。
这里，若每个SRS资源的端口数相同，则可以直接按下式确定每个SRS资源的发送功率：
其中，PCMAX,f,c(i)表示终端的最大发送功率；PO_SRS,b,f,c(qs)表示开环功率控制功率；μ表示子载波因子；MSRS,b,f,c(i)表示任一SRS资源占用资源块数目；αSRS,b,f,c(qs)表示资源集的路径损耗补偿系数；PLb,f,c(qd)表示终端利用参考信号资源索引得到的路径损耗；hb,f,c(i,l)表示闭环功率控制部分。
然后，再将SRS资源的发送功率除以端口数，即可得到每个端口的发送功率，且每个端口的发送功率相同。
在一些实施例中，相应于所述资源集中至少两个SRS资源的端口数目不相等的情况下，所述方法还包括：
终端基于以下至少之一确定第一目标SRS资源的发送功率：
第二目标SRS资源的发送功率、所述第一目标SRS资源的端口数、所述第二目标SRS资源的端口数；
第三目标SRS资源的发送功率、所述第一目标SRS资源的端口数、所述第三目标SRS资源的端口数；
其中，所述第二目标SRS资源为所述资源集中端口数最多的SRS资源；
所述第三目标SRS资源为所述资源集中端口数最少的SRS资源；
所述第一目标SRS资源为所述资源集中端口数非最多或非最少的SRS资源。
这里，通过端口调整因子，使得各个SRS资源的端口的发送功率相同。
应用时，若基于第二目标SRS资源的发送功率确定第一目标SRS资源的发送功率，则第一目标SRS资源可以包括端口数最少的SRS资源；
若基于第三目标SRS资源的发送功率确定第一目标SRS资源的发送功率，则第一目标SRS资源可以包括端口数最多的SRS资源。
在一些实施例中，假设SRS资源集中第二目标SRS资源(即端口数最大的SRS资源)的端口数目为M1，并且假如终端在服务小区c的载波f的上行激活BWP b上采用索引为l的SRS功率控制调整状态在SRS发送时刻i来发送SRS。其中，BWP是指带宽部分(Bandwidth Part)。
根据下式确定所述第二目标SRS资源即(资源集中端口数最多的至少一个SRS资源)的发送功率：
其中，PCMAX,f,c(i)表示终端的最大发送功率；PO_SRS,b,f,c(qs)表示开环功率控制功率；μ表示子载波因子；MSRS,b,f,c(i)表示第二目标SRS资源占用资源块数目；αSRS,b,f,c(qs)表示资源集的路径损耗补偿系数；PLb,f,c(qd)表示终端利用参考信号资源(该参考信号资源与第二目标SRS资源存在关联关系)索引得到的路径损耗；hb,f,c(i,l)表示闭环功率控制部分。
相应地，根据下式确定第一目标SRS资源的发送功率：
其中，N表示所述SRS资源的端口数；M1表示第二目标SRS资源的端口数；Pm SRS,b,f,c(i,qs,l)表示第二目标SRS资源的发送功率。
具体来说，可以先计算出SRS资源集中端口数最多的SRS资源的发送功率，再结合需要计算发送功率的第一目标SRS资源的端口数，计算出第一目标SRS资源的发送功率。即若某个第一目标SRS资源的端口数为N，则该第一目标SRS资源的发送功率是端口数最多的SRS资源的发送功率的倍。
在一些实施例中，假设SRS资源集中第三目标SRS资源(即端口数最少的SRS资源)的端口数目为M2，并且假如终端在服务小区c的载波f的上行激活BWP b上采用索引为l的SRS功率控制调整状态在SRS发送时刻i来发送SRS。
根据下式确定所述第三目标SRS资源(即资源集中端口数最少的至少一个SRS资源)的发送功率：
其中，PCMAX,f,c(i)表示终端的最大发送功率；PO_SRS,b,f,c(qs)表示开环功率控 制功率；μ表示子载波因子；MSRS,b,f,c(i)表示第三目标SRS资源占用资源块数目；αSRS,b,f,c(qs)表示资源集的路径损耗补偿系数；PLb,f,c(qd)表示终端利用参考信号资源(该参考信号资源与第三目标SRS资源存在关联关系)索引得到的路径损耗；hb,f,c(i,l)表示闭环功率控制部分。
相应地，根据下式确定第一目标SRS资源的发送功率：
其中，N表示所述第一目标SRS资源的端口数；M2表示第三目标SRS资源的端口数；Pm SRS,b,f,c(i,qs,l)表示第三目标SRS资源的发送功率。
具体来说，可以先计算出SRS资源集中端口数最少的SRS资源的发送功率，再结合需要计算发送功率的第一目标SRS资源的端口数，计算出第一目标SRS资源的发送功率。即若某个第一目标SRS资源的端口数为N，则该第一目标SRS资源的发送功率是端口数最少的SRS资源的发送功率的倍。
通过上述方法确定各个SRS资源的各端口的发送功率，保证各个端口的发送功率相同，从而使得基站侧可以公平的测量各个端口所对应的信道质量。
在一些实施例中，所述方法还包括：接收来自网络设备的指示信息；
所述接收来自网络设备的指示信息，具体包括：
接收来自网络设备的DCI，所述DCI携带指示信息；所述指示信息用于指示至少一个SRS资源。
这里，网络设备可以通过指示信息指定终端具体采用的SRS资源，终端接收来自网络设备的指示信息后，根据指示信息选择资源集中的SRS资源，根据选择的SRS资源进行数据传输。
具体来说，所述指示信息可以包括：指示的至少一个SRS资源的标识或索引；相应的，配置信息指示的资源集还包括：每个SRS资源对应的唯一的标识或索引。
图4为本公开应用实施例提供的用于非码本传输的SRS资源集的配置方法的流程示意图；如图4所示，所述方法针对8Tx终端，即终端被配置的上 行传输流的数量为8；所述方法包括：
步骤401、网络设备配置用于非码本传输的SRS资源集(SRS resource set)；
第一种配置方法，SRS资源集中包括：最多4个SRS资源(resource)，每个SRS资源有2个端口(port)。
由于SRI占用的bit数仅与资源集中的SRS资源的数目有关，采用第一种配置方法中的最大SRS资源数目与现有协议(如R15)中用于非码本传输的SRS资源的数目一致，如此，可以保证未来通信协议(如R18)用于指示大于8流传输的SRS资源的SRI占用的bit数与相关协议中的相同。
第二种配置方法，SRS资源集中包括：最多4个SRS资源A(记做resource#A)和最多1个SRS资源B(记做resource#B)；每个resource#A具有2个端口，resource#B具有1个端口。
采用第二种配置方法，可以保证配置的SRS资源集可以支持非码本的上行1流传输和奇数流传输，仅比现有协议中的方案带来最多1bit的额外SRI占用开销。
第三种配置方法，SRS资源集中包括：最多4个SRS资源。假设为4个SRS资源，可以分别如下：
resource#1，具有1个端口；
resource#2，具有2个端口；
resource#3，具有2个端口；
resource#4，具有4个端口；
即四个SRS资源的端口数的组合为{1,2,2,4}；
除此之外，4个SRS资源的端口数的组合还可以是{1,1,2,4}，或者，{1,2,4,4}。
若配置的SRS资源集中的SRS资源的数目NSRS小于4，则NSRS个资源的端口数的组合可以是上述4个SRS资源的端口数的组合的子集。
采用第三种配置方法，可以保证支持非码本上行传输的各种流数，并且相比现有协议不占用额外的SRI比特开销。
步骤402、网络设备向终端发送配置信息，所述配置信息用于指示配置的用于非码本传输的SRS资源集。
步骤403、终端接收配置信息，根据配置信息进行数据传输。
通过本公开实施例提供的方法，可以灵活合理的配置SRS资源，在保证相比现有最大4天线上行传输流的SRI指示开销并没有大幅增加、DCI开销没有显著提升的条件下，实现了终端8天线上行传输下基于非码本的大于4流的SRS资源配置方法以及SRI指示。
同时，在保证每一个SRS资源的每个端口的发送功率相同的条件下，相较于现有最大4天线上行传输的SRS资源开销并没有大幅增加，却可以进一步支持终端8天线上行传输的最多8流上行传输。
实际应用时，基于不同的SRS资源集配置方法，会有不同的SRS资源指示(SRS Resource Indication，SRI)指示方式，SRI可指示SRS资源集中的SRS资源。以下针对几种SRS资源集的配置方法分别进行说明。
提供一种应用实施例，基于以上第一种配置方法，根据配置的SRS资源的端口组合以及Lmax，遍历对应{1,2,3…Lmax}的各种SRI组合。如下表格为SRI指示表格的一种示例：
表1-1为一种基于非码本的PUSCH传输的SRI指示(SRI indication for non-codebook based PUSCH transmission)表，Lmax＝2。
表1-1
其中，Lmax表示终端被配置的上行传输流的最大数量，为高层参数PUSCH-ServingCellConfig中携带的maxMIMO-Layers指示的；若没有配置，则Lmax基于终端支持的用于非码本上行传输的最大传输流数确定。
Bit field mapped to index表示映射到索引的位字段。
SRI(s)，NSRS表示SRS资源集中包含的SRS资源的个数。
reserved表示保留位。
表1-2为另一种基于非码本的PUSCH传输的SRI指示表，Lmax＝4。
表1-2
表1-3为再一种基于非码本的PUSCH传输的SRI指示表，Lmax＝6。
表1-3
表1-4为还一种基于非码本的PUSCH传输的SRI指示表，Lmax＝8。

表1-4
提供另一种应用实施例，基于以上第二种配置方法，根据配置的SRS资源的端口组合以及Lmax，遍历对应{1,2,3…Lmax}的各种SRI组合。
不失一般性地，可以假设如下：
当NSRS＝5，5个SRS资源对应的端口数分别为{1，2，2，2，2}；
当NSRS＝4，4个SRS资源对应的端口数分别为{1，2，2，2}；
当NSRS＝3，3个SRS资源对应的端口数分别为{1，2，2}；
当NSRS＝2，2个SRS资源对应的端口数分别为{1，2}；
当NSRS＝1，1个SRS资源对应的端口数分别为{2}或{1}；
那么，在如下几种情况中，SRI不占用比特数：
1)当Lmax＝1时，SRI不占用bit数；
2)当NSRS＝1时，SRI不占用bit数；
3)并且除了下表中列出的情况，其他情况下SRI不占用bit数。
如下是SRI指示表格的一种设计样例：
以下表2-1为第一种基于非码本的PUSCH传输的SRI指示表，Lmax＝2。

表2-1
以下表2-2为第二种基于非码本的PUSCH传输的SRI指示表，Lmax＝3。
表2-2
以下表2-3为第三种基于非码本的PUSCH传输的SRI指示表，Lmax＝4。
表2-3
以下表2-4为第四种基于非码本的PUSCH传输的SRI指示表，Lmax＝5。

表2-4
以下表2-5为第五种基于非码本的PUSCH传输的SRI指示表，Lmax＝6。

表2-5
以下表2-6为第六种基于非码本的PUSCH传输的SRI指示表，Lmax＝7。
表2-6
以下表2-7为第七种基于非码本的PUSCH传输的SRI指示表，Lmax＝8。
表2-7
提供再一种应用实施例，基于以上第三种配置方法，根据配置的SRS资源的端口组合以及Lmax，遍历对应{1,2,3…Lmax}的各种SRI组合，得到各种Lmax以及各种NSRS下的SRI指示表格。
