技术领域
本申请涉及通信领域，并且，更具体地，涉及资源配置方法、装置和系统。
背景技术
在多入多出(multi-input multi-output，MIMO)无线通信系统中，因长期演进(long term evolution，LTE)系统与第五代(5th generation，5G)系统对频谱利用率要求较高，引入了同频组网。但是同频组网在提高频谱利用率的同时产生了小区间干扰的问题。
信道探测参考信号(sounding reference signal，SRS)用于信道的测量估计和质量探测等，调度较为频繁。在引入同频组网时容易造成SRS信噪比降低，系统性能差，是目前亟需解决的问题。

应理解，本申请实施例中，终端设备可以是用于实现终端设备功能的装置，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。

为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
1、天选终端：天选终端的所有物理天线都具备发送信号的能力，以2T4R天选终端为例，2T4R表示该终端共有4根物理天线，每次发送信号用其中2根物理天线，可通过两次发送信号实现4根物理天线发送信号的效果。
2、非天选终端：该终端的发送天线数目<接收天线数目，以2T4R非天选终端为例，2T4R表示该终端共4根物理天线，用于发送信号的物理天线只有2根。
3、SRS资源：SRS的最小分配单位，包括发送SRS能够使用的时域位置、发送SRS能够使用的频域位置、发送SRS能够使用的带宽和发送SRS的天线端口。
4、SRS资源集合：由多个SRS资源组成，不同的SRS资源集合中承载的SRS功能不同。
5、码本(code book，CB)属性的SRS资源集合：该SRS资源集合承载的SRS的功能是用于上行码本选择。
6、天线轮询(antenna switching，AS)属性的SRS资源集合：该SRS资源集合承载的SRS的功能是用于天线轮发。
网络设备为终端设备分配SRS资源时，分配1个用于发送CB属性的SRS的资源集合，该资源集合中最多包含2个SRS资源；分配1个用于发送AS属性的SRS的资源集合，若该终端设备为非天选终端设备，用于发送AS属性的SRS的资源集合中最多包含1个SRS资源，若该终端设备为天选终端设备，用于发送AS属性的SRS的资源集合中最多包含的SRS资源数目为该天选终端设备的物理天线数目，即为不同终端设备分配的SRS资源的数目上限是不同的。此外，相同的SRS资源可以复用在不同的资源集合中，例如，SRS资源res 0，可以既属于CB属性的SRS资源集合，又属于AS属性的SRS资源集合。
LTE与5G系统因对频谱利用率有较高的要求引入了同频组网的方式，从而带来了小区间干扰。SRS调度较为频繁，因此小区间或小区内终端设备设备采用同样资源发送SRS时会出现严重的干扰，从而造成了SRS的信噪比降低。
在一种可能的实施方式中，生成SRS序列的基序列标识受到u，v以及SRS的序列长度Nzc的影响，基序列标识q值的计算公式如下：
Figure PCTCN2022091062-appb-000001
q bar＝Nzc*(u+1)/31
上述公式中的u为组号，可以取值为0-29，可以表示30个小区，v为序列号，可以取值为0或1。
若要提升SRS的信噪比，并期望SRS的邻区干扰随机化，需通过支持SRS的组跳(例如，按照小区标识将30个小区分为一组，使得该组小区的SRS序列同步跳跃)来实现u值的修改，从而在当不同小区的终端设备采用相同资源发送SRS时实现q值的变化。干扰随机化是指终端设备所受干扰会随着时间发生变化。
但是SRS的组跳在实现小区间SRS干扰随机化的过程中，不能实现小区内的SRS干扰随机化。并且SRS的组跳在实现过程中需全网同步开启，若同组的小区没有同步开启，可能在某个时刻两个小区的SRS序列标识跳跃至相同位置，不能实现小区间的SRS干扰随机化，从而影响系统的性能。
可选地，期望SRS的邻区干扰随机化，进一步提升系统性能，还可通过v值的修改来实现，即序列跳。序列跳中v值与伪随机序列相关，根据时隙编号v值会随机产生0或者1两种。从而会使得每个终端设备的SRS序列随着时隙编号的增加而随机性的改变，进而完成SRS干扰随机化。
但个别情况下，例如，调度SRS的带宽为8RB，为SRS配置2梳分，SRS的序列长度Nzc为47，v＝1时，两个连续的u如u＝1和u＝2时，通过上述公式计算得到的q均等于4，也就是说这种情况下出现两个不同小区开启序列跳的q值相同，发生系统错误，从而影响系统性能。
而且上述组跳和序列跳的方案，在网络设备配置的发送SRS的周期较大时，例如大于20毫秒，以NR系统为例，时隙符号为0-19，则终端设备第一次发送SRS和第二次发送SRS的时隙符号会出现重复的情况，每个终端设备的SRS序列随着时隙符号的增加不能随机性的改变，因此达不到SRS干扰随机化的效果。
图2是适用于本申请实施例的一种资源配置方法的流程交互示意图。该方法200包括：
步骤S210，网络设备向第一终端设备发送配置信息。对应的，第一终端设备接收该配置信息。
一种可能的实施方式中，该配置信息指示第一终端设备的第一基序列标识，第一信号的资源，和第一信号的周期中的至少一种。或，该配置信息包括第一终端设备的第一基序列标识，第一信号的资源，和第一信号的周期中的至少一种。其中，该第一终端设备和第二终端设备属于同一个小区，该第二终端设备对应第二基序列标识。
可选地，第一信号为用于信道探测的参考信号，例如SRS。第一信号的资源包括时域资源，频域资源，和码字资源中的至少一种。第一信号的周期为第一终端设备发送第一信 号的周期，以SRS举例，即第一信号的周期为第一终端设备发送SRS的周期。
应理解，SRS仅为第一信号的一种举例，第一信号还可以是其他的用于信道探测的参考信号，或者在技术发展中，第一信号可以为SRS的演化信号，本申请对此不做任何限定。后文以SRS的举例也类似，在后文描述中不再赘述。
示例地，网络设备为第一终端设备配置基序列标识k 1，为第二终端设备配置基序列标识k 2。应理解，基序列标识k 1对应至少一个终端设备，该至少一个终端设备包括第一终端设备；同理，基序列标识k 2也对应至少一个终端设备，该至少一个终端设备包括第二终端设备，并且网络设备为小区内终端设备配置的基序列标识的个数还可以是两个以上，本申请对此不做任何限定。网络设备为基序列标识k 1对应的至少一个终端设备中的其中一个终端设备配置的SRS资源与网络设备为基序列标识k 2对应的至少一个终端设备中的其中一个终端设备配置的SRS资源在频域，时域和码字上可以重叠。
本申请通过给小区内的终端设备配置2个及2个以上的基序列标识，可以使得不同基序列标识的终端设备进行第一信号的资源分配时，为不同的基序列标识的终端设备分配的资源在时域，频域及码字资源上可以重叠。相较于现有技术中为小区内的终端设备配置相同的基序列标识的方案，能够使得小区内的终端设备缩短发送第一信号的周期，从而可以增加小区容量，提升系统性能。
可选地，为小区内的终端设备配置2个及2个以上的基序列标识时，第一信号的周期为T1，为小区内的终端设备配置相同的基序列标识时，第一信号的周期为T2，则T1≤T2。
可选地，网络设备在分配基序列标识时可以通过终端设备所属小区的标识或者在0～29的标识之间随机进行分配。网络设备针对相同基序列标识的终端设备进行第一信号的资源分配时，为不同的终端设备分配的资源在时域，频域及码字资源不重叠。
在一种可能的实施方式中，网络设备为第一终端设备配置的第一信号的资源数量和第二终端设备不同，和/或网络设备为第一终端设备配置的第一信号的周期和第二终端设备不同。该第一终端设备的第一资源在第一时刻与第二资源的频域位置相同，该第一终端设备的第一资源在第二时刻与第三资源的频域位置相同，该第二资源和该第三资源所属的终端设备对应第二基序列标识。其中，第一资源为第一终端设备的第一信号的资源，第二资源和第三资源可以为第二终端设备的第一信号的资源，第二资源和第三资源的天线端口不同。或者第二资源为第二终端设备的第一信号的资源，第三资源为第三终端设备的第一信号的资源，第二终端设备和第三终端设备对应第二基序列标识，第二终端设备和第三终端设备为不同的终端设备。
示例地，网络设备为第一终端设备配置的SRS资源的数量和发送SRS的周期和第二终端设备不同，该第一终端设备的第一SRS资源在第一时刻与第二SRS资源的频域位置相同，该第一终端设备的第一SRS资源在第二时刻与第三SRS资源的频域位置相同，该第二SRS资源和该第三SRS资源所属的终端设备对应第二基序列标识。该第二SRS资源和第三SRS资源所属的终端设备不同，或者该第二SRS资源和第三SRS资源所属的终端设备相同，但该第二SRS资源和第三SRS资源的天线端口不同。
可选地，网络设备为该第一终端设备配置的第一信号的资源数量和该第一信号的周期是该第二终端设备的1/2。例如，第一终端设备的SRS资源的数量和该SRS的发送周期是第二终端设备的1/2。
下面以SRS举例，说明不同情况下网络设备为小区内的终端设备发送第一信号的具体配置。
作为一种示例，第一终端设备和第二终端设备都是非天选终端，网络设备为该第一终端设备的配置1个AS属性的SRS资源，网络设备为该第二终端设备配置2个SRS资源，其中一个是AS属性的SRS资源，另一个是CB属性的SRS资源。网络设备为该第一终端设备的SRS的发送周期配置为字段Tsrs1，为第二终端设备的SRS的发送周期配置为字段Tsrs2，并将Tsrs1配置为Tsrs2的1/2。
作为另一种示例，第一终端设备和第二终端设备都是天选终端，网络设备为该第一终端设备的配置2个AS属性的SRS资源，网络设备为该第二终端设备配置4个SRS资源，其中2个是AS属性的SRS资源，其他2个是CB属性的SRS资源。网络设备为该第一终端设备的SRS的发送周期配置为字段Tsrs1，为第二终端设备的SRS的发送周期配置为字段Tsrs2，并将Tsrs1配置为Tsrs2的1/2。
应理解，上述一种示例中的第一终端设备和第二终端设备可以是以2T4R非天选终端举例，也可以是以1T2R非天选终端举例，但另一种示例中的第一终端设备和第二终端设备是以2T4R天选终端举例。
还应理解，本申请实施例提供的方法还可适用于1T4R终端设备，上述2T4R终端设备和1T2R终端设备仅为举例，本申请对此不做任何限制。
可选地，网络设备为该第一终端设备配置的第一信号的资源数量和该第一信号的周期是该第二终端设备的2/3。例如，第一终端设备的SRS资源的数量和该SRS的发送周期是第二终端设备的2/3。
作为再一种示例，第一终端设备和第二终端设备都是天选终端，网络设备为该第一终端设备配置2个AS属性的SRS资源，网络设备为该第二终端设备配置3个SRS资源，其中2个是AS属性的SRS资源，其余的1个是CB属性的SRS资源。网络设备为该第一终端设备的SRS的发送周期配置为字段Tsrs1，为第二终端设备的SRS的发送周期配置为字段Tsrs2，并将Tsrs1配置为Tsrs2的2/3。
应理解，上述三种示例中网络设备为第一终端设备和第二终端设备分配的不同属性的SRS资源的数目仅为举例，本申请对此不做任何限制。并且网络设备为第一终端设备和第二终端设备配置的第一信号的资源数量和该第一信号的周期的比值除了上述列举的1/2和2/3之外，还可以是其他的比值，本申请对此也不做任何限定。
可选地，步骤S210中的配置信息承载于无线资源控制信令中。例如，该配置信息承载于RRC信令中。
步骤S220，终端设备发送第一信号，该第一信号承载于第一信号的资源上。对应地，网络设备在该资源上接收该第一信号。
示例地，终端设备发送SRS，该SRS承载于SRS资源上。对应地，网络设备在该SRS资源上接收该SRS。
应理解，不同基序列标识的第一信号属于非正交信号，如果第一终端设备和第二终端设备在相同的时频资源上发送第一信号，会产生互相干扰。下面针对步骤S210中不同的第一信号的资源和发送周期的配置方案具体描述第一信号的干扰随机化过程。
图3是适用于本申请实施例的一种确定信道估计的方法的示意图。
可选地，步骤S220后，网络设备需根据不同时刻接收到的第一信号进行信道估计。该方法200还包括：
步骤S310，网络设备获取多个时刻的第一信号接收信道响应矩阵，该多个时刻包括该第一时刻和第二时刻。
示例地，网络设备获取多个时刻的SRS接收信道响应矩阵，该多个时刻包括该第一时刻和第二时刻。
一种可实现的方式，网络设备获取该第一时刻的第一SRS接收信道响应矩阵和第二时刻的第二SRS接收信道响应矩阵。
另一种可实现的方式，网络设备获取第一时刻的第一SRS接收信道响应矩阵，第二时刻的第二SRS接收信道响应矩阵和第三时刻的第三SRS接收信道响应矩阵。
可选地，网络设备获取某个时刻的SRS接收信道响应矩阵包括：网络设备获取某个时刻的SRS接收真实信道响应矩阵和SRS干扰项。
示例地，t 1时刻终端设备A的SRS资源A与终端设备a的SRS资源a 0在频域位置上相同，则对于终端设备A而言，在t 1时刻的SRS接收信道响应矩阵
Figure PCTCN2022091062-appb-000002
其中，H A(t1)为SRS接收真实信道响应矩阵，Inf(a 0)为SRS干扰项。
可选地，该多个时刻中相邻时刻的时间间隔为该第一终端设备发送该第一信号的周期。例如，第一时刻与第二时刻之间的时间间隔为第一终端设备发送该第一信号的周期，第二时刻与第三时刻之间的时间间隔为第一终端设备发送该第一信号的周期。
步骤S320，网络设备对该多个时刻的第一信号接收信道响应矩阵进行加权平均得到该第一终端设备的信道响应矩阵。
示例地，网络设备对该多个时刻的SRS接收信道响应矩阵进行加权平均得到该第一终端设备的信道响应矩阵。
对应于一种可实现的方式，网络设备对该第一SRS接收信道响应矩阵和第二SRS接收信道响应矩阵进行加权平均得到该第一终端设备的第一信道响应矩阵。
对应于另一种可实现的方式，网络设备对该第一SRS接收信道响应矩阵，第二SRS接收信道响应矩阵和第三SRS接收信道响应矩阵进行加权平均得到该第一终端设备的第二信道响应矩阵。
下面以SRS举例，具体说明不同配置场景中第一信号的干扰随机化过程。
作为一种示例，如图4所示，该场景对应于上述步骤S210中作为一种示例的配置SRS资源的方案。其中，第一终端设备和第二终端设备都是非天选终端，网络设备为该第一终端设备的配置1个AS属性的SRS资源，网络设备为该第二终端设备配置2个SRS资源，其中一个是AS属性的SRS资源，另一个是CB属性的SRS资源。网络设备为该第一终端设备的SRS的发送周期配置为字段Tsrs1，为第二终端设备的SRS的发送周期配置为字段Tsrs2，并将Tsrs1配置为Tsrs2的1/2。
第一终端设备可以是图4中终端设备A或终端设备B，终端设备A和终端设备B对应的基序列标识为k1；用A0和B0分别标识终端设备A和终端设备B的SRS资源。第二终端设备可以是图4中的终端设备a或终端设备b，终端设备a和终端设备b对应的基序列标识为k2；用a0与a1标识终端设备a的两个SRS资源，b0和b1标识终端设备b的两个SRS资源。终端设备A和终端设备B发送SRS资源的周期Tsrs2配置为2T，终端设 备a和终端设备b发送SRS资源的周期Tsrs1配置为4T，T为图中所示的相邻时刻的时间间隔。
图4中，终端设备A和终端设备B的SRS资源，与终端设备a和终端设备b的SRS资源的频域位置相同，时域位置分配如图4所示。其中A0资源与a0资源会出现在相同的时频资源位置形成干扰，B0资源与b0资源会出现在同样时频位置互相干扰，同理对于A0资源与b1资源，B0资源与a1资源也会在相同时频域位置互相干扰。
从图4可以看到，对于终端设备A而言，在不同的时刻碰撞到的干扰有所不同，以终端设备A的资源A0为例，在t1时刻碰撞终端设备a的资源a0，在t3时刻碰撞终端设备b的资源b1，由于终端设备a和终端设备b发送SRS的信道不同，相当于终端设备A在不同时刻碰撞的干扰不同，从而可以达到SRS干扰随机化的目的。

Figure PCTCN2022091062-appb-000007
Figure PCTCN2022091062-appb-000008
由于终端设备a和终端设备b的信道不同，因此在SRS接收信道响应统计时相互独立，因而

基于上述基序列标识和SRS资源配置方案，使得SRS干扰随机化，从而通过网络设备的滤波算法，降低了小区内的SRS干扰，有效的提升了上下行的系统性能。
应理解，图4中对于基序列标识为k1对应的终端设备的个数仅为举例，上述加权平均滤波算法仅为示例，网络设备还可通过其他的滤波算法得到第一信道响应矩阵，本申请对此不做任何限制。
作为另一种示例，如图5所示，该场景对应于上述步骤S210中作为一种示例的配置SRS资源的方案。其中，第一终端设备和第二终端设备都是天选终端，网络设备为该第一终端设备的配置2个AS属性的SRS资源，网络设备为该第二终端设备配置4个SRS资源，其中2个是AS属性的SRS资源，2个是CB属性的SRS资源。网络设备为该第一终端设备的SRS的发送周期配置为字段Tsrs1，为第二终端设备的SRS的发送周期配置为字段Tsrs2，并将Tsrs1配置为Tsrs2的1/2。
