背景技术
为了改善服务小区边缘的信号质量，在服务器小区内提供更为均衡的服务，多点协作传输(CoMP，Coordinated Multiple Point transmission)技术在新空口(NR，New Radio)系统中仍然是一种重要的技术手段。针对多传输接收场景(TRP，Transmission-Reception Point)，会涉及非相关联合传输(NC-JT，Non-Coherent Joint Transmission)和联合传输(C-JT，Coherent Joint Transmission)。在无线网络中，很多类型的网络已经可以实现相关联合传输，例如，集中式无线接入网络(C-RAN,Centralized Radio Access Network)架构和站内协作。
相关技术中，针对多个TRP进行相关联合传输的情况，不同TRP之间用于信道估计的探测参考信号(SRS，Sounding Reference Signal)之间的干扰严重，无线通信的可靠性低。

针对不同所述TPR下的终端配置的循环移位参数，所述循环移位参数用于确定SRS资源序列；不同所述TRP下可配置的所述循环移位参数不同。
根据本公开实施例的第四方面，提供一种无线通信装置，所述装置包括：
接收模块，被配置为接收接入网设备发送的指示信息；
其中，所述指示信息用于指示以下至少之一：
针对不同传输接入点TRP下的终端配置的梳状资源结构类型，所述梳状资源结构类型用于确定传输探测参考信号SRS的频域资源；

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，对相关技术中的应用场景进行说明：
在一个实施例中，对于多个TRP进行相关联合传输的情况，不同TRP之间用于信道估计的SRS的干扰问题会更加严重。请参见图2，为了估计联合传输的信道，TRP1需要接收用户1(UE1)的SRS(SRS1)，此时离TRP2距离更近的用户2的SRS成为了干扰。如何消除TRP之间SRS的干扰，是需要解决的问题。需要说明的是，TRP1可以是图2中的关联小区(Coordination Cell)对应的TRP，TRP2可以是服务小区(Serving Cell)对应的TRP。
在一个实施例中，SRS的配置包括时域位置配置和频域位置配置。其中，时域位置配置的参数包括：起始符号位置(Starting symbol location l 0)、持续时长(Time duration
Figure PCTCN2022089400-appb-000001
)和周期与时隙偏移(Periodicity and slot offset)等。频域位置配置的参数包括：探测带宽(Sounding bandwidth)和传输梳 状间隔和梳状偏移(Transmission comb spacing and comb offset)等。请参见图3，示出了带宽部分(BWP，Bandwidth Part)中的最大探测带宽(Maximum Sounding Bandwidth)和实际探测带宽(Actual Sounding Bandwidth)。请参见图4，示出了传输梳状间隔(分别为1、1、3和3)和梳状结构偏移(分别为0、1、0和1)。
相位旋转或者循环移位的获取可以基于如下公式：

为用户的SRS资源的端口数,p i为SRS端口数。
如图5所示，本实施例中提供一种无线通信方法，其中，该方法由接入网设备执行，该方法包括：
步骤51、向终端发送指示信息；
其中，指示信息用于指示以下至少之一：
针对不同传输接入点TRP下的终端配置的梳状资源结构类型，梳状资源结构类型用于确定传输探测参考信号SRS在探测带宽内的频域资源；
针对不同TPR下的终端配置的循环移位参数，循环移位参数用于确定SRS资源序列；不同TRP下可配置的循环移位参数不同。
这里，本公开所涉及的终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。在一些实施例中，该终端可以是Redcap终端或者预定版本的新空口NR终端(例如，R17的NR终端)。
本公开中涉及的接入网设备可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
需要说明的是，TRP可以理解为基站，但在一些场景下，一个小区可能不止通过一个TRP来覆盖，而是由多个TRP联合覆盖，从而增大了小区的覆盖半径，可以减少终端在小区上进行不断的切换。
在一个实施例中，可以是通过RRC消息向终端发送指示信息，其中，指示信息用于指示以下至少之一：针对不同传输接入点TRP下的终端配置的梳状资源结构类型，梳状资源结构类型用于确定传输探测参考信号SRS在探测带宽内的频域资源；针对不同TPR下的终端配置的循环移位参数，循环移位参数用于确定SRS资源序列；不同TRP下可配置的循环移位参数不同。
在一个实施例中，接入网设备向终端发送指示信息；其中，指示信息用于指示以下至少之一：针对不同传输接入点TRP下的终端配置的梳状资源结构类型，梳状资源结构类型用于确定传输探测参考信号SRS在探测带宽内的频域资源；针对不同TPR下的终端配置的循环移位参数，循环移位参数用于确定SRS资源序列；不同TRP下可配置的循环移位参数不同。终端在接收到指示信息后，就可以基于指示信息指示的梳状资源结构类型和循环移位参数传输SRS。示例性地，可以根据基于梳状资源结构类型确定的频域资源和循环移位参数确定的SRS资源序列传输SRS。
在一个实施例中，梳状结构类型包括以下之一：
第二类型梳状结构comb-2；
第三类型梳状结构comb-3；
第四类型梳状结构comb-4；
第六类型梳状结构comb-6。
需要说明的是，梳状结构类型可以是但不限于是上述梳状结构类型。针对不同TRP下的终端可以配置不同的梳状结构类型。当然，也可以针对不同TRP下的终端配置相同的梳状结构类型。
在一个实施例中，循环移位参数包括最大循环移位值和/或循环移位初始值。
需要说明的是，循环移位参数可以不包含最大循环移位值。示例性地，终端在接收到指示信息后，可以基于指示信息指示的梳状结构类型以及梳状结构类型及最大循环移位值之间的映射关系，直接确定最大循环移位值。如此，只要当梳状结构类型确定，终端就可以确定最大循环移位值，实质上，梳状结构类型通过隐性方式指示了最大循环移位值。当然，也可以通过显式指示的方式指示该最大循环移位值，即在接入网设备向终端发送的指示信息中就直接包含该最大循环移位值。
在一个实施例中，向终端发送指示信息；其中，指示信息用于指示：针对不同TPR下的终端配置的循环移位参数，循环移位参数用于确定SRS资源序列；不同TRP下可配置的循环移位参数不同。需要说明的是，基于循环移位参数确定出的不同的TRP的SRS资源序列相互正交。示例性地，不同的TRP下的终端基于相同的基序列和循环移位参数确定出的不同的TRP的SRS资源序列相互正交。
在一个实施例中，指示信息还包括指示以下至少之一：基序列；梳状偏移值。需要说明的是，指示信息可以不直接携带该基序列，可以通过指示标识指示该基序列。示例性地，基序列被分为多个分组，每个分组包含多个基序列，则可以通过标识“x”指示基序列所在的分组，通过标识“y”指示基序列所在分组内的序号。如此，指示信息可以直接携带标识“x”和标识“y”，通过这种隐性指示的方式进行指示。当然，该基序列也可以直接携带在指示信息中，通过显性指示的方式进行指示。
在一个实施例中，向终端发送指示信息；其中，指示信息用于指示以下至少之一：指示SRS频域资源为comb-2梳状结构的信息以及对应的循环移位的最大次数Dmax的信息，其中，Dmax为12或者24。需要说明的是，本公开实施例中用户SRS端口p i的SRS的序列循环移位值α i按下式确定，其中，d 0由网络配置，
Figure PCTCN2022089400-appb-000006
为用户的SRS资源配置的端口数；
Figure PCTCN2022089400-appb-000007
Figure PCTCN2022089400-appb-000008
本公开实施例中，针对上述公式，网络配置的d 0的取值可以为：当Dmax配置为12时，TRP1下的用户(或者终端)的循环移位初始值d 0可配置为{0,2,4,6,8,10}；TRP2下的用户的循环移位初始值d 0可配置为{1,3,5,7,9,11}；或者，当Damx为24时，TRP1下的用户(或者终端)的循环移位初始值d 0可配置为{0,2,4,6,8,10，…，22}；TRP2下的用户的循环移位初始值d 0可配置为{1,3,5,7,9,11，…，23}。
在另一个实施例中，网络配置的d 0的取值可以为：当Dmax配置为12时，TRP1下的用户(或者 终端)的循环移位初始值d 0可配置为{0,1,2,…,5}；TRP2下的用户的循环移位初始值d 0可配置为{0,1,2,…,11}；或者，当Damx为24时，TRP1下的用户(或者终端)的循环移位初始值d 0可配置为{0,1,2,…,5}；TRP2下的用户的循环移位初始值d 0可配置为{0,1,2,…,11}。且用户SRS端口p i的SRS的序列循环移位值α i按下式确定：
Figure PCTCN2022089400-appb-000009
在一个场景实施例中，不同TRP下的终端选用相同的基序列。通过以上处理后，两个不同的TRP(TRP1和TRP2)下的用户可选的循环移位不相同，即使选择了相同的基序列(root sequence)，由于序列循环移位值不相同，也不会相互干扰。因为，两个用户之间的内积为
Figure PCTCN2022089400-appb-000010
其中|α i-α k|的可能取值为
Figure PCTCN2022089400-appb-000011
或者
Figure PCTCN2022089400-appb-000012
因为SRS的频域资源一定是4PRB的倍数，对于comb-2的情况，内积公式中N一定是12或者24的倍数，则内积始终为0，不同TRP下的终端的SRS资源序列相互正交，如此，不同TRP下的终端传输的SRS不会相互干扰。
在一个场景实施例中，不同TRP下的终端选用的基序列不相同。如此，由于基序列不同，两个TRP的用户之间的SRS序列相关性低，干扰也小。
在一个实施例中，向终端发送指示信息；其中，指示信息用于指示：指示SRS频域资源为comb-3梳状结构的信息以及对应的循环移位的最大次数Dmax(对应最大循环移位值)的信息。示例性地，请参见图6，可以按照图6所示的方式进行资源映射，其中，可以配置的梳状结构comb的偏移值为{0,1,2}。循环移位的最大次数D max为8或者16。网络配置的d 0的取值可以是：TRP1下的用户可选的d 0为{0,2,4,6}，或者{0,2,4,6,8,10,…,14}；TRP2下的用户可选的d 0为{1,3,5,7}或者{1,3,4,7,9,…,15}。
在一个实施例中，向终端发送指示信息；其中，指示信息用于指示：指示SRS频域资源为comb-6梳状结构的信息以及对应的循环移位的最大次数Dmax(对应最大循环移位值)的信息。示例性地，请参见图7，可以按照图7所示的方式进行资源映射，其中，可配置的comb的偏移值为{0,1,2,3,4,5}。可用的循环移位的最大次数D max为8。网络配置的d 0的取值：TRP1下的用户可选的d 0为{0,2,4,6}，TRP2下的用户可选的循环移位d 0为{1,3,5,7}。
在本公开实施例中，向终端发送指示信息；其中，指示信息用于指示以下至少之一：针对不同传输接入点TRP下的终端配置的梳状资源结构类型，梳状资源结构类型用于确定传输探测参考信号SRS的频域资源；针对不同TPR下的终端配置的循环移位参数，循环移位参数用于确定SRS资源序列；不同TRP下可配置的循环移位参数不同。这里，由于针对不同传输接入点TRP下的终端配置的梳状资源结构类型进行了分别配置，则基于不同传输接入点TRP下的终端配置的梳妆资源结构类型确定的SRS的频域资源可以不同，和/或，由于针对不同TRP下的终端配置的循环移位参数不同，则基于不同TRP下的终端配置的循环移位参数确定出的SRS资源序列可以正交，相较于给终端统一配置梳状资源结构类型和/或循环移位参数的方式，可以确保两个TRP下的用户分配不同的资源以减少SRS之间的干扰，提升无线通信的可靠性。

需要说明的是，梳状结构类型可以是但不限于是上述梳状结构类型。针对不同TRP下的终端可以配置不同的梳状结构类型。当然，也可以针对不同TRP下的终端配置相同的梳状结构类型。
需要说明的是，当TRP下的终端数量大于数量阈值时，指示信息指示的梳状结构类型可以是A；当TRP下的终端数量小于数量阈值时，指示信息指示的梳状结构类型可以是B，其中，A的资源分布密度小于B的资源分布密度。如此，梳状结构类型可以适应于TRP下的终端数量。示例性地，当TRP下的终端数量大于数量阈值时，指示信息指示的梳状结构类型可以是comb3；当TRP下的终端数量小于数量阈值时，指示信息指示的梳状结构类型可以是comb2。需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图12所示，本实施例中提供一种无线通信方法，其中，该方法由终端执行，该方法包括：
步骤121、接收接入网设备发送的指示信息；其中，指示信息用于指示以下至少之一：针对不同传输接入点TRP下的终端配置的梳状资源结构类型，梳状资源结构类型用于确定传输探测参考信号SRS的频域资源；针对不同TPR下的终端配置的循环移位参数，循环移位参数用于确定SRS资源序列；不同TRP下可配置的循环移位参数不同；梳状结构类型包括以下之一：第二类型梳状结构comb-2；第三 类型梳状结构comb-3；第四类型梳状结构comb-4；第六类型梳状结构comb-6。
需要说明的是，梳状结构类型可以是但不限于是上述梳状结构类型。针对不同TRP下的终端可以配置不同的梳状结构类型。当然，也可以针对不同TRP下的终端配置相同的梳状结构类型。
需要说明的是，当TRP下的终端数量大于数量阈值时，指示信息指示的梳状结构类型可以是A；当TRP下的终端数量小于数量阈值时，指示信息指示的梳状结构类型可以是B，其中，A的资源分布密度小于B的资源分布密度。如此，梳状结构类型可以适应于TRP下的终端数量。示例性地，当TRP下的终端数量大于数量阈值时，指示信息指示的梳状结构类型可以是comb3；当TRP下的终端数量小于数量阈值时，指示信息指示的梳状结构类型可以是comb2。

在一个实施例中，循环移位参数可以不包含最大循环移位值。示例性地，终端在接收到指示信息后，可以基于指示信息指示的梳状结构类型以及梳状结构类型及最大循环移位值之间的映射关系，直接确定最大循环移位值。如此，只要当梳状结构类型确定，终端就可以确定最大循环移位值，实质上，梳状结构类型通过隐性方式指示了最大循环移位值。当然，也可以通过显式指示的方式指示该最大循环移位值，即在接入网设备向终端发送的指示信息中就直接包含该最大循环移位值。
