具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面先对本发明中涉及相关背景做一个简要说明，如下所示：
1、探测信号(Sounding Reference Signal，SRS)
SRS信号是5G/NR(New Radio，新无线)系统中重要的参考信号，广泛用于NR系统中的各种功能中，例如：
(1)用于下行信道状态信息的获取(UE sounding procedure for DL CSI(Down Link Channel State Information，下行信道状态信息)acquisition)；
(2)用于上行波束管理；
(3)用于定位功能；
(4)配合基于码本(codebook-based)的上行传输(包括频域调度和Rank/预编码矩阵指示(precoding matrix indicator，PMI)/调制编码方式(Modulation Coding Scheme，MCS)的确定)；
(5)配合基于非码本(Non-Codebook based)的上行传输(包括频域调度和SRS资源指示(Sounding Reference Signal Resource Indicator，SRI)/MCS的确定)。
网络可以给一个用户设备(User Equipment，UE)配置一个或多个SRS Resource set(SRS资源组)，每个SRS Resource set可以配置1个或多个SRS resource(SRS资源)。
SRS的传输可以分为周期性(Periodic)、半持续(Semi-persistent)、非周期(Aperiodic)几种，详细情况如下：
(1)周期SRS与半持续性SRS
周期SRS是指周期性传输的SRS，其周期和时隙偏移由无线资源控制(Radio Resource Control，RRC)信令配置，终端一旦接收到相应的配置参数，就按照一定的周期发送SRS，直到所述RRC配置失效。周期性SRS的空间相关信息(Spatial Relation Info，通过隐式的方式来指示发送波束)也由RRC信令配置。所述空间相关信息可以指示一个CSI-RS(Channel State Information Reference signal，信道状态信息参考信号)，SSB(Synchronization Signal Block，同步信号块)或者参考SRS，终端根据指示的CSI-RS/SSB的接收波束确定第三SRS资源的发送波束，或者，根据参考SRS资源的发送波束，确定第三SRS资源的发送波束。
半持续性SRS也是周期性传输的SRS，周期和时隙偏移(slot offset)由RRC信令配置，但其激活和去激活信令是通过媒体接入控制单元(Media Access Control Control Element，MAC CE)承载的。终端在接收到激活信令后开始周期性传输SRS，直到接收到去激活信令为止。半持续SRS的空间相关信息(发送波束)通过激活SRS的MAC CE一起承载。
终端接收到RRC配置的周期和时隙偏移后，根据以下公式(1)确定能够用于传输SRS的时隙：
Figure PCTCN2021072569-appb-000001
其中，T SRS和T offset为配置的周期和偏移，n f和
Figure PCTCN2021072569-appb-000002
分别为无线帧和时隙编号。
(2)非周期SRS传输
在NR系统中引入了非周期SRS传输，基站可以通过上行或者下行DCI(Downlink Control Information，下行控制信息)触发终端的SRS传输。用于触发非周期SRS传输的触发信令既可以通过UE(User Equipment，用户设备)专属搜索空间中用于调度PUSCH(Physical Uplink Share Channel，物理上行共享信道)/PDSCH(Physical Downlink Share Channel，物理下行共享信道)的DCI承载，也可以通过公共搜索空间中的DCI format 2_3来承载。其中，DCI format 2_3不仅可以用于触发非周期SRS传输，也可以同时用于配置一组UE或一组载波上的SRS的，传输功率控制(Transmission power control，TPC)命令。
表1：SRS触发信令
Figure PCTCN2021072569-appb-000003
终端接收到非周期SRS触发信令(例如DCI)后，在触发信令所指示的SRS资源集合上进行SRS传输。其中，触发信令与SRS传输之间的时隙偏移(slot offset)由高层信令(RRC)配置。网络侧预先通过高层信令指示终端每个SRS资源集合的配置参数，包括时频资源、序列参数、功率控制参数等。另外，对于触发的SRS资源集合中的每个SRS资源，终端还可以通过该资源的空间相关信息确定在该资源上传输SRS所用的发送波束，该信息通过RRC配置给每个SRS资源。
其中，针对时隙偏移(slot offset)，如果UE在时隙n接收到触发非周期SRS的DCI信令，UE将在时隙
Figure PCTCN2021072569-appb-000004
发送对应集合中的SRS资源，如下图1A所示。其中，k为针对每个集合配置的RRC参数slotOffset，而μSRS和μPDCCH分别为携带触发命令的触发SRS和PDCCH的子载波间距配置。
2、SRS时域资源配置：
startPosition INTEGER(0..13)：l offset∈{0，1，......，13}；
nrofSymbols ENUMERATED{n1，n2，n4}：连续的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号个数
Figure PCTCN2021072569-appb-000005
即：每个SRS资源可以配置在一个时隙的任意符号；
SRS的时域开始符号，
Figure PCTCN2021072569-appb-000006
即从时隙的最后一个符号开始倒数计数。如图1B所示，为SRS时域资源配置的一个示意图。
3、SRS资源频域配置：
SRS的频域配置由38.211-Table 6.4.1.4.3-1中的参数C SRS,B SRS(由RRC信令配置)决定，m SRS,b为SRS传输的物理资源块(Physical Resource Block，PRB)个数，其中b＝B SRS。
表2 SRS带宽配置(SRS bandwidth configuration)
Figure PCTCN2021072569-appb-000007
SRS资源的序列长度由以下公式决定，SRS资源的序列长度即为占用的子载波的数目：
Figure PCTCN2021072569-appb-000008
SRS资源的频域起始位置由以下公式决定：
Figure PCTCN2021072569-appb-000009
其中，
Figure PCTCN2021072569-appb-000010
Figure PCTCN2021072569-appb-000011
其中，K TC为梳状配置的个数。
Figure PCTCN2021072569-appb-000012
为一个RB占用的子载波个数。n shift为高层配置参数。
NR系统支持SRS的跳频，若在满足b hop<B SRS的情况下(其中b hop为RRC配置参数)，终端则以跳频的形式发送SRS信号。其中m SRS,0为SRS跳频的总带宽，m SRS,b为每次跳频发送的PRB个数。且终端由以下公式确定每次跳频的频域位置，n b为频域位置索引参数：
Figure PCTCN2021072569-appb-000013
N b由上述表2确定，n RRC为RRC配置参数，其中F b(n SRS)由以下公式确定：
Figure PCTCN2021072569-appb-000014
其中，无论N b参数的取值，
Figure PCTCN2021072569-appb-000015
参数n SRS表示SRS跳频的次数，对于非周期SRS，SRS跳频的次数由以下公式确定：
Figure PCTCN2021072569-appb-000016
其中，
Figure PCTCN2021072569-appb-000017
Figure PCTCN2021072569-appb-000018
为连续的OFDM符号个数(为RRC配置参数)，R为重复因子(由RRC配置)用于指示不跳频的重复OFDM符号个数。例如，当R＝1时，以1个OFDM符号为单位跳频；当R＝2时，以2个OFDM符号为单位跳频。
对于周期和半周期SRS，SRS跳频的次数由以下公式确定：
Figure PCTCN2021072569-appb-000019
其中，T SRS和T offset为配置的周期和偏移，n f和
Figure PCTCN2021072569-appb-000020
分别为无线帧和时隙编号，
Figure PCTCN2021072569-appb-000021
为每帧包含的时隙个数。
按照目前的协议配置，网络设备为每个SRS资源配置带宽和跳频的参数。SRS资源在配置好的带宽中进行传输。若下一时刻需要改变SRS探测的信道的频域位置或者带宽大小，则需要通过RRC进行配置。而且，考虑到临近带宽的信道条件类似，引入跨子带的SRS以探测不同频段位置的信道，以达到在同等的条件下可以探测到更大的信道带宽。并且通过调整参数的配置，可以达到部分跳频的效果，以支持更强的覆盖和更大的容量。
为了解决上述问题，可能的处理方式分别是灵活配置SRS传输带宽，以及跨子带传输SRS。以上两种方法具有更好的灵活性，可以更加动态地指示传输SRS资源的频域位置以及带宽大小
