Description

通信方法、通信装置、芯片及计算机可读存储介质
本申请要求于2022年9月30日提交中国专利局、申请号为202211213854.9、申请名称为“通信方法、通信装置、芯片及计算机可读存储介质”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。
技术领域
本申请涉及通信领域，尤其涉及通信方法、通信装置、芯片及计算机可读存储介质。
背景技术
信道探测参考信号(sounding reference signal，SRS)是一种终端设备向接入网设备(例如基站)发送的上行参考信号。SRS用于接入网设备获取该终端设备的上行(uplink，UL)信道。或者，SRS用于接入网设备根据信道互易性获取该终端设备的下行(downlink，DL)信道，从而根据该下行信道对该终端设备做数据调度。
长期演进系统(long term evolution，LTE)和新无线(new radio，NR)中的SRS采用的序列(即SRS序列)是基序列(base sequence)的循环移位(cyclic shift，CS)。不同的终端设备采用的SRS序列可以是不同基序列的CS，也可以是相同基序列的不同CS。对于不同的基序列来说，无论采用相同或不同的循环移位值，得到的SRS序列之间均存在干扰。也就是说，若接入网设备将基于不同基序列的相同或不同循环移位值得到的SRS序列分配给不同的终端设备，且这些终端设备在相同的时频资源上发送各自被分配的SRS序列，则这些SRS序列之间存在的干扰会造成终端设备间的干扰。
由于两个SRS序列之间的干扰会受到这两个SRS序列的循环移位之间的差值的影响，目前采用循环移位跳变的方式随机化SRS序列间的干扰。采用循环移位跳变的方式随机化SRS序列间的干扰能达到较好的干扰随机化效果。在实际应用场景中，既有支持循环移位跳变的终端设备，也有不支持循环移位跳变的终端设备。当接入网设备将支持循环移位跳变的终端设备对应的SRS端口与不支持循环移位跳变的终端设对应的SRS端口配置在同一把梳齿上进行复用时，二者的信道估计性能可能会遭受严重损失。如何在充分利用循环移位跳变带来的干扰随机化效果的同时，保证上述情况下信道估计性能不受损失是亟待解决的问题。
发明内容
本申请实施例公开了通信方法、通信装置、芯片及计算机可读存储介质，在充分利用循环移位跳变带来的干扰随机化效果的同时，保证信道估计性能不受损失。
第一方面，本申请实施例提供一种通信方法，该方法包括：第一通信装置接收第一信息；所述第一通信装置根据所述第一信息，确定第一端口的循环移位范围，所述第一端口为所述第一通信装置对应的端口中的一个，所述第一端口的循环移位范围包括两个或两个以上循环移位值；所述第一通信装置在所述第一端口上发送参考信号。可选的，所述第一端口占用的循环移位值随所述参考信号的发送时刻和/或发送频率变化，所述第一端口占用的循环移位值属于所述第一端口的循环移位范围。所述第一端口可以是一个SRS资源集中的一个SRS资源包括的若干SRS端口中的一个。所述第一端口占用的循环移位值是指所述第一通信装置在所述第一端口上发送所述参考信号占用的循环移位值。本申请中，第一端口的循环移位范围可理解为该第一端口可用的循环移位范围。或者说，第一端口可采用第一端口的循环移位范围中的任意循环移位值。所述第一端口的循环移位范围可以是第一循环移位范围的真子集，第一通信装置采用的循环移位值在该第一循环移位范围内跳变可能会造成与其他通信装置的SRS序列之间的干扰，第一通信装置采用的循环移位值在该第一端口的循环移位范围内跳变能够避免或减少与其他通信装置的SRS序列之间的干扰。第一循环移位范围可视为现有的支持循环移位跳变的通信装置可用的循环移位范围。本申请中不限定第一 端口的循环移位范围内的循环移位值的粒度和第一循环移位范围内的循环移位值的粒度。例如，第一循环移位范围可以是[0,2π](对应于整个时延域)；可以是(将整个时延域等分)，也可以是{0,1·2π/MZC,…,(MZC-1)·2π/MZC}(将整个时延域MZC等分)，还可以包括其他取值。其中，c表示正整数常量，表示最大循环移位数量，MZC表示SRS序列长度。本申请实施例中，第一通信装置根据第一信息，确定第一端口的循环移位范围。第一通信装置对应的第一端口占用该循环移位范围中的任意循环移位值发送参考信号时，能够避免或减少在将支持循环移位跳变的终端设备对应的SRS端口与不支持循环移位跳变的终端设对应的SRS端口配置在同一把梳齿上进行复用时，二者的信道估计性能可能会遭受严重损失的问题。或者说，第一通信装置根据第一信息，确定第一端口的循环移位范围，能够在充分利用循环移位跳变带来的干扰随机化效果的同时，保证信道估计性能不受损失。

首先，对本申请实施例涉及的一些概念进行阐述。
1、SRS、SRS资源、SRS的梳齿(comb)、SRS发送
SRS是一种终端设备向接入网设备(例如基站)发送的上行参考信号。接入网设备根据终端设备发送 的SRS获取该终端设备的UL信道。或者，接入网设备根据信道互易性获取该终端设备的DL信道，从而根据该DL信道对该终端设备做数据调度。下文中的用户设备(user equipment，UE)和/或用户可视为终端设备。
SRS资源由接入网设备(例如基站)通过高层参数半静态配置，包括：
个SRS端口每个SRS端口会对应特定的时频码资源。在理想情况下，各个SRS端口是正交的。每个SRS端口会对应终端设备的物理天线或者虚拟天线。
SRS的梳齿(comb)：一把SRS的梳齿上的频域子载波呈等间隔分布，梳齿数量KTC∈{2,4,8}由接入网设备(下文以基站为例)通过高层参数半静态配置，其决定了SRS发送带宽中包含的梳齿数量。图1为本申请提供的三种不同梳齿数量下一把梳齿的示例。图1中，每个格子表示一个资源元素(resource element，RE)，黑色格子是不同梳齿数量下一把梳齿占用的RE位置的示例。一次SRS发送对应一个SRS资源内的连续R个OFDM符号。重复因子R∈{1,2,4}由基站通过高层参数repetitionFactor半静态的配置。一次SRS发送对应的连续R个OFDM符号中的第一个OFDM符号在SRS资源内的编号能够被R整除。
2、SRS的发送带宽、跳频带宽及跳频周期
SRS的发送带宽、跳频带宽及跳频周期是根据高层参数及协议预定义表格确定的。当基站没有配置频率缩放因子PF时，SRS发送带宽为基站根据SRS获取的信道对应的带宽范围，SRS跳频带宽为单次SRS发送后基站获取的信道对应的带宽范围，跳频带宽小于等于扫描带宽，跳频周期为基站获取发送带宽对应的信道所需要的SRS发送次数；当基站通过高层参数配置了频率缩放因子PF时，SRS的发送带宽、跳频带宽及跳频周期不变，但由于单次SRS发送的带宽变为原先的1/PF，这种情况下发送带宽为基站根据SRS获取的信道对应的带宽范围的PF倍，SRS跳频带宽为单次SRS发送后基站获取的信道对应的带宽范围的PF倍。图2为本申请实施例提供的一种发送带宽和跳频带宽的示例。图2中，每个格子频域上表示一个资源块(resource block，RB)，SRS的带宽为16RB，跳频带宽为4RB，跳频周期为4，左图没有配置PF，右图配置了PF＝2。
3、SRS的循环移位
LTE和NR的SRS采用的序列是基序列(base sequence)的循环移位：
其中，α为循环移位值，为实数；δ＝log2(KTC)，为整数；u，v为SRS基序列组中某个基序列的索引，为整数；j为虚数单位；MZC为SRS序列的长度，为正整数；n为SRS序列中元素的索引，为整数，序列元素(即SRS序列中的元素)按照索引由小到大的顺序依次映射在SRS资源对应的子载波索引由小到大的各个子载波上。
上述基序列可以是Zadoff-Chu(ZC)序列生成的序列，例如是ZC序列本身，或者是ZC序列通过循环移位扩充或者截取生成的序列。例如，长度为N的ZC序列为zq(n),n＝0,1,…,N-1，则由该ZC序列生成的长度为M的序列可以表示为：zq(m mod N),m＝0,1,…,M-1。其中，长度为N的ZC序列可以表示为如下形式：
其中，N为正整数；q为ZC序列的根指标，且为与N互质且小于N的正整数。
SRS端口pi对应的循环移位αi由下式定义：

其中，表示端口数量(即SRS资源包括的SRS端口的数量)，为最大循环移位数量，根据KTC取值分别定义，参阅表1：
表1
的含义可以理解为将时延域等分成份，也可以理解为将相位值2π等分成份，每个循环移位值对应每份的起始点。为循环移位参考索引，由基站通过高层参数transmissionComb半静态配置。
对于同一个基序列来说，采用不同的循环移位值α，可以得到不同的SRS序列。当α1和α2满足α1mod 2π≠α2mod 2π时，由基序列和循环移位α1得到的序列与由基序列和循环移位α2得到的序列是相互正交的，即互相关系数为零。其中，长度为M的序列s1(m)和s2(m),m＝0,1,…,M-1,的互相关系数定义为：表示s2(m)的共轭。由于基于同一个基序列和不同循环移位值得到的SRS序列相互正交，基站可以将基于同一个基序列和不同循环移位值得到的SRS序列分配给不同的用户，这些用户可以在相同的时频资源上发送这些SRS序列。本申请中，用户是指终端设备，例如手机。当用户与基站之间的信道在SRS序列长度内平坦时，这些SRS序列不会造成用户间干扰。
对于不同的基序列来说，无论采用相同或不同的循环移位值，得到的SRS序列之间均存在干扰。也就是说，基站将基于不同基序列的相同或不同循环移位值得到的SRS序列分配给不同的用户，这些用户可以在相同的时频资源上发送这些SRS序列，当用户与基站之间的信道在SRS序列长度内平坦时，这些SRS序列会造成用户间干扰。
例如，两个小区分别使用基序列s1、s2，每个小区内有两个用户，每个小区内的两个用户使用同一个基序列的2个不同的循环移位值，则有4个用户可以在相同的时频资源上发送SRS。参阅表2，UE1和UE2位于同一小区，UE3和UE4位于同一小区，UE1和UE2均使用基序列s1，UE1以基序列s1的循环位移值α1作为SRS序列进行SRS发送，UE2以基序列s1的循环位移α2作为SRS序列进行SRS发送，UE3和UE4均使用基序列s2，UE3以基序列s2的循环位移α3作为SRS序列进行SRS发送，UE4以基序列s2的循环位移α4作为SRS序列进行SRS发送。
表2
假设四个UE与基站之间的信道在SRS序列占据的M个子载波上平坦且分别为h1、h2、h3和h4。在SRS序列占据的M个子载波中的第k个子载波上，基站的接收信号y(k)为：
为了估计UE1的信道h1，基站可采用如下公式将接收信号与该UE使用的SRS序列进行相关操作：
其中，为UE3对UE1的信道估计产生的干扰，为UE4对UE1的信道估计产生的干扰。可以看出，两个UE的SRS序列之间的干扰会受到这两个SRS序列的循环移位之间的差值的影响。
由于两个UE的SRS序列之间的干扰会受到这两个序列的循环移位之间的差值的影响，可采用循环移位跳变的方式随机化SRS序列间的干扰。循环移位跳变一种可能的实现方式中，SRS的循环移位由下式决定：
其中，nf为系统帧号(system frame number，SFN)；为子载波配置μ下每个帧包含的时隙数；为每个时隙包含的符号数；为子载波配置μ下一个帧内的时隙号l0∈{0,1,…,13}为SRS资源在时隙内的时域起始位置；为SRS资源内的OFDM符号索引；MZC为SRS序列的长度。
循环移位跳变另一种可能的实现方式为：不同时刻SRS的循环移位遵循某种循环移位变化图样。例如，SRS端口pi遵循的循环移位变化图样指示pi依次以基序列的循环移位1、循环移位2、3、…、循环移位d作为SRS序列进行SRS发送，d为大于1的整数。也就是说，SRS端口pi先以基序列的循环位移1作为SRS序列进行SRS发送，然后以基序列的循环位移2作为SRS序列进行SRS发送，然后以基序列的循环位移3作为SRS序列进行SRS发送，依次类推，以基序列的循环位移d作为SRS序列进行SRS发送之后，重新开始以基序列的循环位移1作为SRS序列进行SRS发送。
如背景技术部分所述，采用循环移位跳变的方式随机化SRS序列间的干扰能达到较好的干扰随机化效果。然而，在实际应用场景中，既有支持循环移位跳变的终端设备，也有不支持循环移位跳变的终端设备。本申请中，支持循环移位跳变的终端设备是指可采用循环移位跳变的方式随机化SRS序列间的干扰的终端设备。或者说，支持循环移位跳变的终端设备具备采用循环移位跳变的方式随机化SRS序列间的干扰的能力或功能。本申请中，不支持循环移位跳变的终端设备是指不能采用循环移位跳变的方式随机化SRS序列间的干扰的终端设备。或者说，不支持循环移位跳变的终端设备不具备采用循环移位跳变的方式随机化SRS序列间的干扰的能力或功能。当接入网设备(例如基站)将支持循环移位跳变的终端设备对应的SRS端口与不支持循环移位跳变的终端设对应的SRS端口配置在同一把梳齿上进行复用时，二者的信道估计性能可能会遭受严重损失。因此，如何在充分利用循环移位跳变带来的干扰随机化效果的同时，保证上述情况下信道估计性能不受损失是亟待解决的问题。

在一种可能的实现方式中，上述第一信息指示第一集合，上述第一集合包括上述第一端口不可用的循环移位索引，上述第一端口的循环移位范围由上述第一集合确定。第一端口不可用的循环移位索引可理解为：不支持循环移位跳变的通信装置对应的SRS端口占用的循环移位索引或者不支持循环移位跳变的通信装置对应的SRS端口占用的循环移位值对应的循环移位索引，即已经被不支持循环移位跳变的SRS端口占用的循环移位索引或者已经被不支持循环移位跳变的SRS端口占用的循环移位值对应的循环移位索引。可选的，上述第一信息以位图的方式指示上述第一集合包括的循环移位索引，上述位图中的N个比特与N个循环移位索引一一对应，上述N个比特中任意比特的值为1或0代表与上述任意比特对应的循环移位索引属于上述第一集合。上述N为大于1的整数。N可以等于最大循环移位数量还可以是其他取值，本申请不作限定。在该实现方式中，第一端口的循环移位范围由第一集合确定，可以准确地确定第一端口的循环移位范围。
在一种可能的实现方式中，上述第一信息指示第一集合、梳齿数量KTC以及第二缩放因子γ，上述第一集合包括上述第一端口不可用的循环移位索引，上述第一端口的循环移位范围由上述第一集合、上述梳齿数量以及上述第二缩放因子共同确定。步骤402一种可能的实现方式如下：第一通信装置通过梳齿数量KTC确定最大循环移位数量参阅表1；通过上述最大循环移位数量上述第一集合以及上述第二缩放因子γ，确定上述第一端口的循环移位范围。上述第一信息指示第一集合、梳齿数量以及第二缩放因子可替换为：上述第一信息指示第一集合和梳齿数量，上述第二缩放因子是预定义的，即第一信息不需要指示第二缩放因子。可选的，第一通信装置采用上述公式(1)或公式(2)确定上述第一端口的循环移位范围。在该实现方式中，第一端口的循环移位范围由第一集合、梳齿数量以及第二缩放因子共同确定，可以准确地确定第一端口的循环移位范围。
在一种可能的实现方式中，上述第一信息指示第二集合，上述第二集合包括一个或多个循环移位索引，上述第二集合为所有循环移位索引构成的全集的真子集，上述第一端口的循环移位范围由上述第二集合确定。上述第二集合包括一个或多个循环移位索引可视为第一端口可用的循环移位索引。这里的所有循环移位索引构成的全集可以是也可以是{0,1,…,MZC-1}，还可以包括其他取值。其中，表示最大循环移位数量，MZC表示SRS序列长度。可选的，上述第一信息以位图的方式指示上述第二集合包括的循环移位索引，上述位图中的N个比特与N个循环移位索引一一对应，上述N个比特中任意比特的值为1或0代表与上述任意比特对应的循环移位索引属于上述第二集合。上述N为大于1的整数。N可以等于最大循环移位数量也可以等于SRS序列长度MZC，还可以是其他取值，本申请不作限定。在该实现方式中，第一端口的循环移位范围由第二集合确定，可以准确地确定第一端口的循环移位范围。

403、第一通信装置在第一端口上发送参考信号。
第一通信装置在第一端口上发送参考信号可以是：第一通信装置根据第一端口的循环移位范围，在第一端口上发送参考信号。第一通信装置在第一端口上发送参考信号时，第一端口占用的循环移位值属于第一端口的循环移位范围。
可选的，第一端口占用的循环移位值随上述参考信号的发送时刻和/或发送频率变化，上述第一端口占用的循环移位值属于上述第一端口的循环移位范围。第一端口占用的循环移位值是指发送参考信号占用的循环移位值，参考信号可以是SRS。第一端口占用的循环移位值随上述参考信号的发送时刻变化可以理解为：第一端口在不同时刻发送SRS占用的循环移位值不同。例如，第一通信装置在第一时刻通过第一端口发送SRS 1时占用循环移位值1，第一通信装置在第二时刻通过该第一端口发送SRS 2时占用循环移位值2；其中，该第一时刻和该第二时刻不同，该循环移位值1和该循环移位值2不同。第一端口占用的循环移位值随上述参考信号的发送频率变化可以理解为：第一端口在不同频率资源上发送SRS占用的循环移位值不同。例如，第一通信装置在频率资源1上通过第一端口发送SRS 1时占用循环移位值1，第一通信装置在频率资源2上通过该第一端口发送SRS 2时占用循环移位值2；其中，频率资源1和频率资源2不同，该循环移位值1和该循环移位值2不同，频率资源1和频率资源2对应于相同的时间资源或不同的时间资源。
本申请实施例中，第一通信装置根据第一信息，确定第一端口的循环移位范围。第一通信装置在占用该循环移位范围中的任意循环移位值发送参考信号时，能够避免或减少在将支持循环移位跳变的终端设备对应的SRS端口与不支持循环移位跳变的终端设对应的SRS端口配置在同一把梳齿上进行复用时，二者的信道估计性能可能会遭受严重损失的问题。或者说，第一通信装置根据第一信息，确定第一端口的循环移位范围，能够在充分利用循环移位跳变带来的干扰随机化效果的同时，保证信道估计性能不受损失。
下面通过几个实施例来介绍第一信息可能的格式以及第一通信装置根据第一信息确定第一端口的循环移位范围可能的实现方式。
实施例一：第一信息指示第一端口的循环移位范围。第一信息指示第一端口的循环移位范围可视为：第一信息指示第一区间长度，上述第一端口的循环移位范围由上述第一端口配置的循环移位值和上述第一区间长度共同确定。
可选的，第一信息中的第一字段的取值与第一端口的循环移位范围具有对应关系。第一字段占用一个或多个比特(bit)。或者说，第一信息中的第一字段的取值与第一区间长度具有对应关系。
示例11：第一信息中的第一字段占用1bit。第一信息中的第一字段的取值与第一端口的循环移位范围的对应关系可如下：
若第一字段的取值为0，则该第一字段指示第一端口的循环移位范围为[0,2π]，即第一端口的循环移位范围不受限制；或者说，若第一字段的取值为0，则该第一字段指示第一区间长度为2π。
若第一字段的取值为1，则该第一字段指示第一端口的循环移位范围为或者说，若第一字段的取值为1，则该第一字段指示第一区间长度为
其中，β>0为预定义的或第二通信装置(例如基站)通过第一信息指示的第一缩放因子。可选的，第一信息还指示KTC、以及第一通信装置根据KTC得到参阅表1；根据以及得到参阅上述公式(6)和公式(7)；根据β以及得到根据以及得到第一信息指示第一区间长度、KTC、以及β时，或指示第一区间长度、KTC、以及时，第一通信装置可利用第一信息确定第一端口的循环移位范围。应理解，第一信息中的第 一字段可视为确定第一端口的循环移位范围或者第一区间长度的公式，可能由第一信息指示的KTC、 以及β为确定第一端口的循环移位范围或者第一区间长度所需的参数。
以为例，当第一字段的取值为0时，该第一字段指示第一端口的循环移位范围不受限制，即[0,2π]，该第一字段的取值对应第二通信装置没有将第一端口与不支持循环移位跳变的通信装置对应的SRS端口配置在同一把梳齿上进行码分复用的情况；当该第一字段的取值为1时，该第一字段指示第一端口的循环移位范围为即将时延域等分成8份(索引为0～7)，第一端口使用的循环移位值可以为第x份的起始点与第x份的中点之间的任意值，该第一字段的取值对应第二通信装置将第一端口与不支持循环移位跳变的通信装置对应的SRS端口配置在同一把梳齿上进行码分复用的情况。可理解，若第二通信装置没有将第一端口与不支持循环移位跳变的通信装置对应的SRS端口配置在同一把梳齿上进行码分复用，则向第一通信装置发送包含取值为0的第一字段的第一信息，该第一通信装置根据该第一信息可获知第一端口的循环移位范围不受限制，即第一端口的循环移位范围为[0,2π]；若第二通信装置将第一端口与不支持循环移位跳变的通信装置对应的SRS端口配置在同一把梳齿上进行码分复用，则向第一通信装置发送包含取值为1的第一字段的第一信息，该第一通信装置根据该第一信息确定第一端口的循环移位范围，例如
示例12：第一信息中的第一字段占用2bit。第一字段的取值与第一端口的循环移位范围的对应关系可如下：
若第一字段的取值为00，则该第一字段指示第一的循环移位范围为[0,2π]，即第一端口的循环移位范围不受限制；或者说，若第一字段的取值为00，则该第一字段指示第一区间长度为2π；
若第一字段的取值为01，该第一字段指示第一端口的循环移位范围为或者说，若第一字段的取值为01，则该第一字段指示第一区间长度为
若第一字段的取值为10，该第一字段指示第一端口的循环移位范围为或者说，若第一字段的取值为10，则该第一字段指示第一区间长度为
若第一字段的取值为11，该第一字段指示第一端口的循环移位范围为或者说，若第一字段的取值为11，则该第一字段指示第一区间长度为
其中，β3>β2>β1>0为预定义的或第二通信装置通过第一信息指示的第一缩放因子。可选的，第一信息还指示KTC、以及第一通信装置根据KTC得到参阅表1；根据以及得到参阅上述公式(6)和公式(7)；根据β1、β2、β3以及得到以及根据以及得到以及第一信息指示第一区间长度、KTC、β1、β2以及β3中时，或指示第一区间长度、KTC、以及时，第一通信装置可利用第一信息确定第一端口的循环移位范围。应理解，第一信息中的第一字段可视为确定第一端口的循环移位范围或者第一区间长度的公式，可能由第一信息指示的KTC、β2以及β3为确定第一端口的循环移位范围或者第一区间长度所需的参数。
以β2＝1,β3＝2为例，当第一字段的取值为00时，该第一字段指示第一端口的循环移位范围不受限制，即[0,2π]，该第一字段的取值对应第二通信装置没有将第一端口与不支持循环移位跳变的通信装置对应的SRS端口配置在同一把梳齿上进行码分复用的情况；当该第一字段的取值为01时，该第一字段指示第一端口的循环移位范围为即将时延域等分成8份(索引为0～7)，第一端口使用的循环移位值可以为第x份的起始点与第x份的中点之间的任意值；当第一字段的取值为10时，该第一字段指示第一端口的循环移位范围为即将时延域等分成8份(索引为0～7)，第一端口使用的循环移位值可以为第x份的起始点与第(x+1)份的起始点之间的任意值；当第一字段的取值为11时，该第一字段指示第一端口的循环移位范围为即将时延域等分成8份(索引为0～7)，第一端口使用的循环移位值可以为第x份的起始点与第(x+2)份的起始点之间的任意值。若第一字段的取值为01、10、11中的任一个，则该第一字段对应第二通信装置将第一端口与不支持循环移位跳变的通信装置对应的SRS端口配置在同一把梳齿上进行码分复用的情况。
第一字段的具体取值可视第二通信装置为同一梳齿上所有不支持循环移位跳变的通信装置对应的SRS端口(下文简称不支持循环移位跳变的SRS端口)配置的循环移位索引、该第二通信装置为该梳齿上所有支持循环移位跳变的通信装置对应的SRS端口(下文简称支持循环移位跳变的SRS端口)配置的循环移位索引以及该梳齿上所有支持循环移位跳变的SRS端口对应的信道的时延扩展而定。或者说，第二通信装置可以根据不支持循环移位跳变的SRS端口对循环移位索引的占用情况、支持循环移位跳变的SRS端口对循环移位索引的占用情况以及支持循环移位跳变的SRS端口对应的信道的时延扩展生成指示支持循环移位跳变的SRS端口的循环移位范围的第一信息。第二通信装置还可根据其他因素生成第一信息，本申请不作限定。支持循环移位跳变的SRS端口(例如第一端口)的循环移位范围内的任意循环移位值需要保证支持循环移位跳变的SRS端口占用该任意循环移位值进行SRS发送后其对应的时延域信道与不支持循环移位跳变的SRS端口对应的时延域信道尽量不发生重叠。通过第一信息指示第一端口的循环移位范围，第一通信装置结合预定义的或第二通信装置通过第一信息指示的第一缩放因子即可得到其对应的SRS端口的循环移位范围，从而在保证不支持循环移位跳变的SRS端口与支持循环移位跳变的SRS端口的信道估计性能不受损失的前提下，充分利用了循环移位跳变带来的干扰随机化效果。下面结合附图和举例来描述第二通信装置生成指示支持循环移位跳变的SRS端口的循环移位范围的第一信息的实现方式。
图5为本申请实施例提供的一种SRS端口对应的时延域信道的示意图。假设复用在同一把梳齿上的SRS端口对应的信道的时延扩展近似相同，黑色垂直虚线将黑色水平实线代表的时延域等分成8份(索引为0～7)，曲线501表示不支持循环移位跳变的SRS端口对应的时延域信道，实曲线502表示支持循环移位跳变的SRS端口在不进行循环移位跳变(即占用基站配置的循环移位值)时对应的时延域信道，虚曲线503表示支持循环移位跳变的SRS端口进行循环移位跳变后对应的时延域信道。箭头表示支持循环移位跳变的SRS端口可用的循环移位范围。应理解，只要支持循环移位跳变的SRS端口进行循环移位跳变后的循环移位值仍处在箭头表示的范围内，不支持循环移位跳变的SRS端口与支持循环移位跳变的SRS端口的信道估计性能就不会遭受损失。
以图5中的第一行为例，第二通信装置(例如基站)为不支持循环移位跳变的各个SRS端口分别配置了循环移位索引0、2、4、6，为支持循环移位跳变的各个SRS端口分别配置了循环移位索引1、5，第二通信装置通过某种方式估计(如根据历史信息预测)支持循环移位跳变的各个SRS端口对应的信道的时延扩展均较小(例如，配置了循环移位索引1的SRS端口对应的信道的时延径集中分布在8等分时延域中第1份的起始点与第1份的中点之间，配置了循环移位索引5的SRS端口对应的信道的时延径集中分布在8等分时延域中第5份的起始点与第5份的中点之间)，则第二通信装置可以通过取值为“01”的第一字段指示配置了循环移位索引1的SRS端口可用的循环移位范围为以及指示配置了循环移位索引5的SRS端口可用的循环移位范围为配置了循环移位索引1的SRS端口对应的信道的 时延径集中分布在8等分时延域中第1份的起始点与第1份的中点之间，该SRS端口对应的信道的时延径在整体向右移位时延域的(8等分时延域中一份的)后，该SRS端口对应的信道的时延径分布在8等分时延域中第1份的中点与第1份的终止点(第2份的起始点)之间，不会影响各SRS端口的信道估计性能；配置了循环移位索引5的SRS端口对应的信道的时延径集中分布在8等分时延域中第5份的起始点与第5份的中点之间，该SRS端口对应的信道的时延径在整体向右移位时延域的(8等分时延域中一份的)后，该SRS端口对应的信道的时延径分布在8等分时延域中第5份的中点与第5份的终止点(第6份的起始点)之间，不会影响各SRS端口的信道估计性能，因此β1的取值可以为支持循环移位跳变的通信装置结合预定义的或第二通信装置通过第一信息指示的第一缩放因子即可得到配置了循环移位索引1的SRS端口可用的循环移位范围为配置了循环移位索引5的SRS端口可用的循环移位范围为这样既可以保证不支持循环移位跳变的SRS端口与支持循环移位跳变的SRS端口的信道估计性能不受损失，又可以充分利用循环移位跳变带来的干扰随机化效果。应理解，如图5中的第二行和第三行所示，第二通信装置可采用类似的方式生成指示支持循环移位跳变的SRS端口的循环移位范围的第一信息，这里不再详述。
实施例一中，第一信息指示第一端口的循环移位范围，可以准确地确定第一端口的循环移位范围。
实施例二：第一信息指示第一集合，上述第一集合包括上述第一端口不可用的循环移位索引，上述第一端口的循环移位范围由上述第一集合确定。

示例21：第一信息指示第一集合，即第一端口不可用的循环移位索引，第一端口的循环移位范围为：
其中，表示上述第一端口的循环移位范围，j表示循环移位索引，表示上述最大循环移位数量，γ为第二缩放因子，B(j)＝1表示循环移位索引j已经被不支持循环移位跳变的SRS端口占用，B(j)＝0表示循环移位索引j没有被不支持循环移位跳变的SRS端口占用(可能被支持循环移位跳变的SRS端口占用，也可能没有被任何SRS端口占用)。可选的，0≤γ≤1为预定义的或第二通信装置(例如基站)通过第一信息指示的第二缩放因子。
示例22：第一信息指示第一集合，即第一端口不可用的循环移位索引，第一端口的循环移位范围为：

实施例二中，第一信息指示第一集合，第一通信装置根据该第一集合可以准确地确定第一端口的循环移位范围。
实施例三：上述第一信息指示第二集合，上述第二集合包括一个或多个循环移位索引，上述第二集合为所有循环移位索引构成的全集的真子集，上述第一端口的循环移位范围由上述第二集合确定。可选的，上述所有循环移位索引构成的全集被划分为ε个预定义的真子集，上述第二集合为ε个真子集中的一个，上述第一信息指示第二集合，上述第一端口的循环移位范围由所述第二集合确定。上述ε为大于1的整数。第一信息指示的第二集合为若干个预定义的真子集中的一个，可以以较小的开销确定第一端口的循环移位范围。

以为例，当所有循环移位索引构成的全集被划分为{0,2,4,6}、{1,3,5,7}两个预定义子集时，第二通信装置可以通过第一信息指示第二集合为{0,2,4,6}或{1,3,5,7}。例如，第一信息中的第二字段指示第二集合，若该第二字段的取值为0，则该第二字段指示第二集合为{0,2,4,6}；若该第二字段的取值为1，则该第二字段指示第二集合为{1,3,5,7}。当所有循环移位索引构成的全集被划分为{0,1,2,3}、{4,5,6,7}两个预定义集合时，第二通信装置可以通过第一信息指示第二集合为{0,1,2,3}或{4,5,6,7}。当所有循环移位索引构成的全集被划分为{0,4}、{1,5}、{2,6}、{3,7}四个预定义子集时，第二通信装置可以通过第一信息指示第二集合为{0,4}、{1,5}、{2,6}、{3,7}中的任一集合。例如，第一信息中的第二字段指示第二集合，若该第二字段的取值为00，则该第二字段指示第二集合为{0,4}；若该第二字段的取值为01，则该第二字段指示第二集合为{1,5}；若该第二字段的取值为10，则该第二字段指示第二集合为{2,6}；若该第二字段的取值为11，则该第二字段指示第二集合为{3,7}。进一步地，以第二集合为{0,2,4,6}，为例，则第一端口的循环移位范围为
第二通信装置通过上述第一信息指示没有被不支持循环移位跳变的SRS端口占用的循环移位索引的集合，即第二集合，第一通信装置结合预定义的或第二通信装置通过第一信息指示的第三缩放因子δ即可得到第一端口的循环移位范围，以便在保证不支持循环移位跳变的SRS端口与支持循环移位跳变的SRS端口的信道估计性能不受损失的前提下，充分利用了循环移位跳变带来的干扰随机化效果。
实施例三中，第一信息指示第二集合，第一通信装置根据该第二集合可以准确地确定第一端口的循环移位范围。

图7为本申请实施例提供的另一种通信交互方法流程图。如图7所示，该方法包括：
701、第二通信装置向第一通信装置发送第一信息。
相应的，第一通信装置接收来自第二通信装置的第一信息。第二通信装置可以是接入网设备，例如基站。第一通信装置为终端设备。第一信息用于指示第一端口对应的循环移位变化图样。上述第一端口为上述第一通信装置对应的端口中的一个。第一端口可以是一个SRS资源集中的一个SRS资源包括的若干SRS端口中的一个。本申请实施例以第一端口为例来描述第一通信装置确定SRS端口的循环移位范围的流程。应理解，第一通信装置可采用类似的方式确定任意SRS端口的循环移位范围。
第一信息可以承载于一个或者多个格式相同/不同的信令之上，例如无线资源控制(radio resource control，RRC)信令、介质接入控制(media access control，MAC)控制元素(control element，CE)、下 行控制信息(downlink control information，DCI)等。
第二通信装置在发送第一信息之前，生成第一信息。第一信息用于第一通信装置确定第一端口对应的循环移位变化图样。可选的，第二通信装置根据不支持循环移位跳变的SRS端口对循环移位索引的占用情况和/或支持循环移位跳变的SRS端口对循环移位索引的占用情况和/或支持循环移位跳变的SRS端口对应的信道的时延扩展生成第一信息。
702、第一通信装置根据第一信息，确定第一端口对应的循环移位变化图样。
上述第一端口对应的循环移位变化图样包括的循环移位索引构成的集合为所有循环移位索引构成的全集的真子集。所有循环移位索引构成的全集可以是也可以是{0,1,…,MZC-1}，还可以包括其他取值。其中，c表示正整数常量，表示最大循环移位数量，MZC表示SRS序列长度。
703、第一通信装置在第一端口上发送参考信号。
第一通信装置在第一端口上发送参考信号可以是：第一通信装置在第一端口上发送参考信号，第一端口占用的循环移位值按照第一端口对应的循环移位变化图样随参考信号的发送时刻和/或发送频率变化。
可选的，第一信息中的第一字段指示第一端口对应的循环移位变化图样，该第一字段占用的比特数与候选的循环移位变化图样的数量有关。包含不同顺序的相同循环移位索引的循环移位变化图样(如{0,2,4,6}与{4,6,0,2})可以被视为不同的循环移位变化图样，也可以被视为不同起始点下的相同的循环移位变化图样。起始点可以是第二通信装置为第一端口配置的循环移位索引，也可以通过其他方式确定。下文中包含不同顺序的相同循环移位索引的循环移位变化图样被视为不同起始点下的相同的循环移位变化图样，起始点为第二通信装置为第一端口配置的循环移位索引。
考虑到现有协议中属于一个SRS资源的若干个SRS端口占用的循环移位索引呈均匀分布，所有循环移位索引构成的全集可能以ε1为间隔被等分为ε1个循环移位变化图样，ε1为的约数。考虑到用于不同TRP进行信道估计的SRS之间存在时延差，所有循环移位索引构成的全集可能被连续地等分为ε2个循环移位变化图样，ε2为的约数。所有循环移位索引构成的全集还可能以其他的方式被划分为若干个循环移位变化图样，本申请实施例不作限定。
以为例，当所有循环移位索引构成的全集被划分为{0,2,4,6}、{1,3,5,7}两个循环移位变化图样时，第二通信装置可以通过第一信息指示支持循环移位跳变的SRS端口(例如第一端口)对应的循环移位变化图样为{0,2,4,6}或{1,3,5,7}。当所有循环移位索引构成的全集被划分为{0,1,2,3}、{4,5,6,7}两个循环移位变化图样时，第二通信装置可以通过第一信息指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{0,1,2,3}或{4,5,6,7}。例如，第一信息中的第一字段指示第一端口对应的循环移位变化图样，若该第一字段的取值为0，则该第一字段指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{0,1,2,3}；若该第一字段的取值为1，则该第一字段指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{4,5,6,7}。当所有循环移位值构成的全集被划分为{0,4}、{1,5}、{2,6}、{3,7}四个循环移位变化图样时，第二通信装置可以通过第一信息指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{0,4}、{1,5}、{2,6}、{3,7}中的任一个。例如，第一信息中的第一字段指示第一端口对应的循环移位变化图样，若该第一字段的取值为00，则该第一字段指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{0,4}；若该第一字段的取值为01，则该第一字段指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{1,5}；若该第一字段的取值为10，则该第一字段指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{2,6}；若该第一字段的取值为11，则该第一字段指示支持循环移位跳变的SRS端口对应的循环移位变化图样为{3,7}。进一步地，以第一信息指示支持循环移位跳变的SRS端口pi对应的循环移位变化图样为{0,2,4,6}，第二通信装置为SRS端口pi配置的循环移位索引为4为例，则SRS端口pi对应的循环移位变化图样为{4,6,0,2}，即SRS端口pi占用的循环移位索引随SRS发送时刻和/或发送频率以4,6,0,2,4,6,0,2,…的规律进行变化。
本申请实施例中，第一通信装置根据第一信息，确定第一端口对应的循环移位变化图样。第一通信装置在按照该循环移位变化图样发送参考信号时，能够避免或减少在将支持循环移位跳变的终端设备对应的SRS端口与不支持循环移位跳变的终端设对应的SRS端口配置在同一把梳齿上进行复用时，二者的信道估计性能可能会遭受严重损失的问题。或者说，第一通信装置根据第一信息，确定第一端口对应的循环移位变化图样，能够在充分利用循环移位跳变带来的干扰随机化效果的同时，保证信道估计性能不受损失。
