Description

一种干扰处理的方法，相关装置以及设备
本申请要求于2021年03月31日提交中国国家知识产权局、申请号为202110352344.9、发明名称为“一种干扰处理的方法，相关装置以及设备”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
本申请实施例涉及通信领域，尤其涉及一种干扰处理的方法，相关装置以及设备。
背景技术
在现网部署中，当邻小区的用户数据负载较低时，服务小区常常使用高阶调制。基于此，邻小区的信道状态信息参考信号(channel state information reference signal，CSI-RS)以及跟踪参考信号(CSI-RS for tracking，TRS)，会与本小区发送的物理下行共享信道(physical downlink shared channel，PDSCH)数据或TRS所占用的资源元素(resource element，RE)相互碰撞，导致服务小区的TRS或PDSCH在该RE位置上解码失败。又由于发送选用高阶调制，所以个别RE的污染对性能的影响很大。
目前，通常对于邻小区发送导频的具体RE位置会通过做速率匹配来避免资源的重叠所带来的碰撞干扰。具体为，服务小区的基站根据速率匹配的图案(rate-matching pattern)将对应位置的RE空出来，且不发送PDSCH数据，由于通过速率匹配将部分邻区所用的TRS或CSI-RS位置空了出来而不发送PDSCH数据，所以在这些对应位置上不会有来自邻区导频的对服务小区下行PDSCH数据的干扰。
然而，由于速率匹配避免干扰，会浪费许多时频资源，且速率匹配使得邻区CSI-RS或TRS的位置上也无法发送服务小区PDSCH数据，从而降低频谱利用率。
发明内容
本申请提供了一种干扰处理的方法，相关装置以及设备，能够通过SCS配置信息确定干扰消除处理方式，并且在邻小区对服务小区造成干扰的资源元素RE位置上通过所确定的干扰消除处理方式进行干扰消除，因此能够提升在邻小区对服务小区造成干扰的RE位置进行干扰消除的效率，且不影响发送PDSCH数据，从而提升频谱利用率。
第一方面，本申请提供了一种干扰处理的方法。该方法可以由终端设备执行，或者也可以由配置于终端设备中的芯片执行，本申请对此不作限定。该方法包括：终端设备接收服务小区的网络设备发送的辅助信令，该辅助信令包括邻小区的配置信息，邻小区的配置信息包括参考信号配置信息以及子载波间隔SCS配置信息，邻小区是与服务小区相邻的小区，服务小区是对终端设备进行服务的小区，然后根据参考信号配置信息确定第一位置，该第一位置为邻小区对服务小区造成干扰的资源元素RE位置，再根据SCS配置信息确定干扰消除处理方式，最后使用所确定的干扰消除处理方式在第一位置上进行干扰消除。
在该实施方式中，通过辅助信令所包括的邻小区的配置信息中的参考信号配置信息确 定邻小区对服务小区造成干扰的RE位置，然后再根据邻小区的配置信息中的SCS配置信息确定干扰消除处理方式，然后使用该干扰消除处理方式在邻小区对服务小区造成干扰的RE位置上进行干扰消除，由于干扰消除处理方式是根据邻小区的SCS配置信息确定的，因此该干扰消除处理方式能够更高效的消除邻小区对服务小区造成干扰的RE位置上的干扰，且不影响发送PDSCH数据，从而提升频谱利用率。
在本申请的一种可选实施方式中，参考信号配置信息包括信道状态信息参考信号CSI-RS配置信息与跟踪参考信号TRS配置信息中至少一项。基于此，第一位置为CSI-RS的资源元素RE位置与TRS的RE位置中至少一项。
在该实施方式中，具体限定在参考信号配置信息包括CSI-RS配置信息与TRS配置信息中至少一项，从而能够确定第一位置为CSI-RS的资源元素RE位置与TRS的RE位置中至少一项，由此使得在实际应用中，终端设备通过不同的配置信息确定对应的RE位置，从而提升本方案的可行性。
在本申请的一种可选实施方式中，在终端设备接收服务小区的网络设备发送的辅助信令之前，还能够向服务小区的网络设备发送第一指示信息，该第一指示信息用于指示终端设备支持进行信道状态信息参考信号干扰消除CSI-RS-IC与跟踪参考信号干扰消除TRS-IC中至少一项，CSI-RS-IC为对第一干扰进行消除，TRS-IC为对第二干扰进行消除，第一干扰为邻小区的CSI-RS对服务小区数据的干扰，第二干扰为邻小区的TRS对服务小区数据和/或TRS的干扰。例如，当第一指示信息指示终端设备支持进行CSI-RS-IC时，那么终端设备所接收到的辅助信令中包括CSI-RS配置信息以及SCS配置信息。其次，当第一指示信息指示终端设备支持进行TRS-IC时，那么终端设备所接收到的辅助信令中包括TRS配置信息以及SCS配置信息。再次，当第一指示信息指示终端设备支持进行CSI-RS-IC，且能够支持进行TRS-IC时，那么终端设备所接收到的辅助信令中包括CSI-RS配置信息，TRS配置信息以及SCS配置信息。
在该实施方式中，由于第一指示信息能够指示终端设备所支持的干扰消除方式，基于此，服务小区的网络设备根据第一指示信息，确定终端设备支持的干扰消除方式，由此向终端设备发送辅助信令中所携带的配置信息是根据终端设备支持的干扰消除确定，降低资源传输的消耗，也能提升终端设备根据配置信息更高效的完成所支持的干扰消除。
在本申请的一种可选实施方式中，当邻小区的配置信息更新后，辅助信令包括增量式更新后的邻小区的配置信息。具体地，在邻小区的配置信息更新后，能够得到更新后的邻小区的配置信息，为了保证终端设备能够更准确使用配置信息进行干扰消除，需要再次发送辅助信令，为了减少信息传输的资源消耗，此时辅助信令中并不包括更新后的邻小区的配置信息，而是包括将更新后的邻小区的配置信息与更新前的邻小区的配置信息之间，进行更新的那部分配置信息(即增量式更新后的邻小区的配置信息)。例如，若更新前的邻小区的配置信息为邻小区的配置信息A，那么终端设备所接收到的辅助信令会包括邻小区的配置信息A。基于此，若更新后的邻小区的配置信息为邻小区的配置信息B，终端设备所接收到的辅助信令包括增量式更新后的邻小区的配置信息(邻小区的配置信息B-邻小区的配置信息A)。
在该实施方式中，在邻小区的配置信息更新后，重新发送辅助信令能够保证终端设备能够更准确使用配置信息进行干扰消除，提升终端设备进行干扰消除的准确性以及可靠性。其次，仅发送增量式更新后的邻小区的配置信息，不占用其他数据传输的资源，由此降低信息传输的资源消耗。
在本申请的一种可选实施方式中，辅助信令还包括每个邻小区的小区标识，邻小区的小区标识指示邻小区的配置信息来源于邻小区。例如，若与服务小区相邻的小区包括邻小区1以及邻小区2，而终端设备所接收到的辅助信令包括CSI-RS配置信息1，TRS配置信息1以及SCS配置信息1，与CSI-RS配置信息2，TRS配置信息2以及SCS配置信息2。此时终端设备并不知道配置信息来源于哪个邻小区。基于此，若辅助信令还能够包括小区标识1以及小区标识2，且小区标识1指示CSI-RS配置信息1，TRS配置信息1以及SCS配置信息1来源于邻小区1，小区标识2指示CSI-RS配置信息2，TRS配置信息2以及SCS配置信息2来源于邻小区2。那么终端设备能够根据小区标识确定，每个不同配置信息来源于哪个邻小区。
在该实施方式中，通过邻小区的小区标识指示邻小区的配置信息来源于邻小区，能够使得终端设备得知配置信息的来源，由此可知，后续所确定的第一位置以及所进行的干扰消除具体是对哪个邻小区进行，由此能够更为准确且高效的进行干扰消除，从而提升干扰消除的效率。
在本申请的一种可选实施方式中，当邻小区的配置信息更新后，辅助信令包括增量式更新后的邻小区的配置信息以及每个邻小区的小区标识。与前述可选实施例类似，在邻小区的配置信息更新后，能够得到更新后的邻小区的配置信息，为了保证终端设备能够更准确使用配置信息进行干扰消除，需要再次发送辅助信令，为了减少信息传输的资源消耗，此时辅助信令中并不包括更新后的邻小区的配置信息，而是包括将更新后的邻小区的配置信息与更新前的邻小区的配置信息之间，进行更新的那部分配置信息(即增量式更新后的邻小区的配置信息)。应理解，每个小区的小区标识不会因为邻小区的配置信息更新而更新，即每个小区的小区标识是预设固定的。
在该实施方式中，在邻小区的配置信息更新后，重新发送辅助信令能够保证终端设备能够更准确使用配置信息进行干扰消除，提升终端设备进行干扰消除的准确性以及可靠性。其次，通过邻小区的小区标识指示邻小区的配置信息来源于邻小区，能够使得终端设备得知配置信息的来源，能够更为准确且高效的进行干扰消除，进一步地提升干扰消除的效率。再次，仅发送增量式更新后的邻小区的配置信息，不占用其他数据传输的资源，由此降低信息传输的资源消耗。
在本申请的一种可选实施方式中，在终端设备向服务小区的网络设备发送第一指示信息之后，且终端设备接收服务小区的网络设备发送的辅助信令之前，终端设备还能够对L个邻小区的干扰强度进行测量，得到L个干扰强度测量结果，该干扰强度测量结果与邻小区一一对应，然后在L个干扰强度测量结果中确定M个干扰强度测量结果，M个干扰强度测量结果大于其他(L-M)个干扰强度测量结果，即M个干扰强度测量结果对应的邻小区比其他(L-M)个干扰强度测量结果对应的邻小区的干扰强度要强，因此将M个干扰强度测量 结果对应的邻小区确定为待处理小区，最后终端设备向服务小区的网络设备发送第二指示信息，该第二指示信息携带待处理小区的小区标识，第二指示信息用于指示服务小区的网络设备向终端设备发送待处理小区的配置信息，前述L≥2，M≥1，且M＜L。
在该实施方式中，终端设备计算邻小区的干扰强度，由于其他干扰程度较弱的邻小区对服务小区的干扰较小，因此终端设备能够向服务小区的网络设备发送第二指示信息，反馈所有邻小区中干扰强度较强的干扰源(即待处理小区)，使得服务小区的网络设备在后续发送辅助信令时，不对干扰较小的邻小区的配置信息进行发送，降低信息传输的资源消耗。
在本申请的一种可选实施方式中，辅助信令包括待处理小区的配置信息。
在该实施方式中，由于服务小区的网络设备在发送辅助信令时，该辅助信令中仅包括发送干扰强度较强的待处理小区的配置信息，在保证能够消除邻小区干扰的基础上，降低信息传输的资源消耗。
在本申请的一种可选实施方式中，当邻小区的配置信息更新后，辅助信令包括更新后的邻小区的配置信息。具体地，在邻小区的配置信息更新后，能够得到更新后的邻小区的配置信息，为了保证终端设备能够更准确使用配置信息进行干扰消除，需要再次发送辅助信令，此时辅助信令中直接包括更新后的邻小区的配置信息。例如，若更新前的邻小区的配置信息为邻小区的配置信息A，那么终端设备所接收到的辅助信令会包括邻小区的配置信息A。基于此，若更新后的邻小区的配置信息为邻小区的配置信息B，终端设备所接收到的辅助信令包括更新后的邻小区的配置信息(邻小区的配置信息B)。
在该实施方式中，在邻小区的配置信息更新后，重新发送辅助信令能够保证终端设备能够更准确使用配置信息进行干扰消除，提升终端设备进行干扰消除的准确性以及可靠性。
在本申请的一种可选实施方式中，辅助信令包括多个邻小区的配置信息。基于此，终端设备能够根据多个邻小区的CSI-RS配置信息与多个邻小区的TRS配置信息中至少一项，确定多个邻小区的第二位置，该邻小区的第二位置为邻小区的CSI-RS的资源元素RE位置与邻小区的与TRS的RE位置中至少一项。然后终端设备对多个邻小区的第二位置的干扰强度进行测量，得到多个待处理测量结果，该待处理测量结果与邻小区的第二位置一一对应，再在多个待处理测量结果中确定目标测量结果，并且将目标测量结果对应的邻小区的第二位置确定为第一位置。应理解，目标测量结果可以为一个或多个，但目标测量结果的数量是小于待处理测量结果的数量的，目标测量结果的具体数量本实施例中不做限定。
具体地，在多个待处理测量结果中确定目标测量结果可以通过两种不同的方式确定。第一种方式为根据预设数量阈值确定，该预设数量阈值为具体数量，例如预设数量阈值为2，那么目标测量结果的最大数量即为2，基于此，对多个待处理测量结果按照干扰程度的大小进行排序，将多个待处理测量结果中干扰程度的大小为前2个的待处理测量结果，或干扰程度的大小为第1个的待处理测量结果确定为目标测量结果。第二种方式为根据预设百分比阈值确定，该预设百分比阈值为多个待处理测量结果中能够确定目标测量结果数量的最大百分比，例如预设数量阈值为50％，且待处理测量结果的数量为10，那么目标测量结果的最大数量即为5，基于此，对10个待处理测量结果按照干扰程度的大小进行排序，将10个待处理测量结果中干扰程度的大小为前5个的待处理测量结果确定为目标测量结果。 应理解，在实际应用中还可以设定干扰强度阈值，若多个待处理测量结果的干扰程度的大小均小于干扰强度阈值，则说明多个邻小区对服务小区的干扰较弱，此时可以选择暂时不进行干扰消除，具体此处不做限定。
在该实施方式中，终端设备在得到所有邻小区对服务小区造成干扰的RE位置后，对所有邻小区对服务小区造成干扰的RE位置进行干扰测量，从中选择对服务小区干扰较强的邻小区对服务小区造成干扰的RE位置，并且在这些位置会上进行干扰消除，在保证对干扰较强的RE进行干扰消除的基础上。避免了在干扰较弱的RE位置进行干扰消除的资源消耗，由此提升干扰消除的可靠性，并且降低干扰消除的资源消耗。
在本申请的一种可选实施方式中，在终端设备不向服务小区的网络设备发送第一指示信息的场景下，终端设备接收服务小区的网络设备通过广播方式发送的辅助信令，该辅助信令包括邻小区的配置信息，邻小区的配置信息包括CSI-RS配置信息，TRS配置信息以及SCS配置信息。
在该实施方式中，由于终端设备不向服务小区的网络设备发送第一指示信息，为了保证服务小区内所有的终端设备均能进行干扰消除，会将CSI-RS配置信息，TRS配置信息以及SCS配置信息均下发至所有终端设备，因此无论终端设备支持CSI-RS-IC以及TRS-IC中任意一种或多种消除方式，均可以通过邻小区的配置信息进行干扰消除，从而提升干扰消除的可靠性。
第二方面，本申请提供了另一种干扰处理的方法。该方法可以由网络设备执行，或者也可以由配置于网络设备中的芯片执行，本申请对此不作限定。该方法包括：网络设备向终端设备发送辅助信令，其中，辅助信令包括邻小区的配置信息，邻小区的配置信息包括参考信号配置信息以及子载波间隔SCS配置信息，参考信号配置信息用于确定第一位置，第一位置为邻小区对服务小区造成干扰的资源元素RE位置，SCS配置信息用于确定干扰消除处理方式，干扰消除处理方式被用于在第一位置上进行干扰消除，邻小区是与服务小区相邻的小区，服务小区是对终端设备进行服务的小区，网络设备为服务小区的网络设备。
在该实施方式中，网络设备向终端设备发送辅助信令，由于辅助信令包括的邻小区的配置信息中的信道状态信息参考信号CSI-RS配置信息与跟踪参考信号TRS配置信息中至少一项，以及SCS配置信息。使得终端设备能够通过辅助信令所包括的邻小区的配置信息中的信道状态信息参考信号CSI-RS配置信息与跟踪参考信号TRS配置信息中至少一项，确定CSI-RS的资源元素RE位置与TRS的RE位置中至少一项，然后再根据邻小区的配置信息中的SCS配置信息确定干扰消除处理方式，然后使用该干扰消除处理方式在CSI-RS的资源元素RE位置与TRS的RE位置中至少一项上进行干扰消除，由于干扰消除处理方式是根据邻小区的SCS配置信息确定的，因此该干扰消除处理方式能够更高效的消除在CSI-RS或TRS的RE位置上的干扰，且不影响在CSI-RS或TRS上发送PDSCH数据，从而提升频谱利用率。
在本申请的一种可选实施方式中，参考信号配置信息包括信道状态信息参考信号CSI-RS配置信息与跟踪参考信号TRS配置信息中至少一项。基于此，第一位置为CSI-RS的资源元素RE位置与TRS的RE位置中至少一项。
在该实施方式中，具体限定在参考信号配置信息包括CSI-RS配置信息与TRS配置信息 中至少一项，从而能够确定第一位置为CSI-RS的资源元素RE位置与TRS的RE位置中至少一项，由此使得在实际应用中，使得终端设备能够通过不同的配置信息确定对应的RE位置，从而提升本方案的可行性。
在本申请的一种可选实施方式中，在网络设备向终端设备发送辅助信令之前，网络设备还可以接收终端设备发送的第一指示信息，该第一指示信息用于指示终端设备支持进行信道状态信息参考信号干扰消除CSI-RS-IC与跟踪参考信号干扰消除TRS-IC中至少一项，CSI-RS-IC为对第一干扰进行消除，TRS-IC为对第二干扰进行消除，第一干扰为邻小区的CSI-RS对服务小区数据的干扰，第二干扰为邻小区的TRS对服务小区数据和/或TRS的干扰。例如，当第一指示信息指示终端设备支持进行CSI-RS-IC时，那么网络设备向终端设备发送的辅助信令中包括CSI-RS配置信息以及SCS配置信息。其次，当第一指示信息指示终端设备支持进行TRS-IC时，那么网络设备向终端设备发送的辅助信令中包括TRS配置信息以及SCS配置信息。再次，当第一指示信息指示终端设备支持进行CSI-RS-IC，且能够支持进行TRS-IC时，那么网络设备向终端设备发送的辅助信令中包括CSI-RS配置信息，TRS配置信息以及SCS配置信息。
在该实施方式中，由于第一指示信息能够指示终端设备所支持的干扰消除方式，基于此，服务小区的网络设备根据第一指示信息，确定终端设备支持的干扰消除方式，由此向终端设备发送辅助信令中所携带的配置信息是根据终端设备支持的干扰消除确定，降低资源传输的消耗，也能提升终端设备根据配置信息更高效的完成所支持的干扰消除。
在本申请的一种可选实施方式中，当邻小区的配置信息更新后，辅助信令包括增量式更新后的邻小区的配置信息。具体地，在邻小区的配置信息更新后，能够得到更新后的邻小区的配置信息，为了保证终端设备能够更准确使用配置信息进行干扰消除，需要再次发送辅助信令，为了减少信息传输的资源消耗，此时辅助信令中并不包括更新后的邻小区的配置信息，而是包括将更新后的邻小区的配置信息与更新前的邻小区的配置信息之间，进行更新的那部分配置信息(即增量式更新后的邻小区的配置信息)。例如，若更新前的邻小区的配置信息为邻小区的配置信息A，那么网络设备向终端设备发送的辅助信令会包括邻小区的配置信息A。基于此，若更新后的邻小区的配置信息为邻小区的配置信息B，那么网络设备向终端设备发送的辅助信令包括增量式更新后的邻小区的配置信息(邻小区的配置信息B-邻小区的配置信息A)。
在该实施方式中，在邻小区的配置信息更新后，重新发送辅助信令能够保证终端设备能够更准确使用配置信息进行干扰消除，提升终端设备进行干扰消除的准确性以及可靠性。其次，仅发送增量式更新后的邻小区的配置信息，不占用其他数据传输的资源，由此降低信息传输的资源消耗。
在本申请的一种可选实施方式中，辅助信令还包括每个邻小区的小区标识，邻小区的小区标识指示邻小区的配置信息来源于邻小区。例如，若与服务小区相邻的小区包括邻小区1以及邻小区2，而终端设备所接收到的辅助信令包括CSI-RS配置信息1，TRS配置信息1以及SCS配置信息1，与CSI-RS配置信息2，TRS配置信息2以及SCS配置信息2。此时终端设备并不知道配置信息来源于哪个邻小区。基于此，若辅助信令还能够包括小区标 识1以及小区标识2，且小区标识1指示CSI-RS配置信息1，TRS配置信息1以及SCS配置信息1来源于邻小区1，小区标识2指示CSI-RS配置信息2，TRS配置信息2以及SCS配置信息2来源于邻小区2。使得终端设备能够根据小区标识确定，每个不同配置信息来源于哪个邻小区。
在该实施方式中，通过邻小区的小区标识指示邻小区的配置信息来源于邻小区，能够使得终端设备得知配置信息的来源，由此可知，后续所确定的第一位置以及所进行的干扰消除具体是对哪个邻小区进行，由此能够更为准确且高效的进行干扰消除，从而提升干扰消除的效率。
在本申请的一种可选实施方式中，当邻小区的配置信息更新后，辅助信令包括增量式更新后的邻小区的配置信息以及每个邻小区的小区标识。与前述可选实施例类似，在邻小区的配置信息更新后，能够得到更新后的邻小区的配置信息，为了保证终端设备能够更准确使用配置信息进行干扰消除，需要再次发送辅助信令，为了减少信息传输的资源消耗，此时辅助信令中并不包括更新后的邻小区的配置信息，而是包括将更新后的邻小区的配置信息与更新前的邻小区的配置信息之间，进行更新的那部分配置信息(即增量式更新后的邻小区的配置信息)。应理解，每个小区的小区标识不会因为邻小区的配置信息更新而更新，即每个小区的小区标识是预设固定的。
在该实施方式中，在邻小区的配置信息更新后，重新发送辅助信令能够保证终端设备能够更准确使用配置信息进行干扰消除，提升终端设备进行干扰消除的准确性以及可靠性。其次，通过邻小区的小区标识指示邻小区的配置信息来源于邻小区，能够使得终端设备得知配置信息的来源，能够更为准确且高效的进行干扰消除，进一步地提升干扰消除的效率。再次，仅发送增量式更新后的邻小区的配置信息，不占用其他数据传输的资源，由此降低信息传输的资源消耗。
在本申请的一种可选实施方式中，在网络设备接收终端设备发送的第一指示信息之后，且网络设备向终端设备发送辅助信令之前，网络设备还能够接收终端设备发送的第二指示信息，其中，第二指示信息携带待处理小区的小区标识，待处理小区为M个干扰强度测量结果对应的邻小区，M个干扰强度测量结果是在L个干扰强度测量结果中确定的，M个干扰强度测量结果大于其他(L-M)个干扰强度测量结果，L个干扰强度测量结果是对L个邻小区的干扰强度进行测量得到的，干扰强度测量结果与邻小区一一对应，L≥2，M≥1，且M＜L。基于此，网络设备根据待处理小区对应的小区标识确定待处理小区。
在该实施方式中，由于其他干扰程度较弱的邻小区对服务小区的干扰较小，因此终端设备能够向服务小区的网络设备发送第二指示信息，反馈所有邻小区中干扰强度较强的干扰源(即待处理小区)，使得网络设备能够根据待处理小区对应的小区标识确定待处理小区，因此在发送辅助信令时，不对干扰较小的邻小区的配置信息进行发送，降低信息传输的资源消耗。
在本申请的一种可选实施方式中，辅助信令包括待处理小区的配置信息。
在该实施方式中，由于服务小区的网络设备在发送辅助信令时，该辅助信令中仅包括发送干扰强度较强的待处理小区的配置信息，在保证能够消除邻小区干扰的基础上，降低 信息传输的资源消耗。
在本申请的一种可选实施方式中，当邻小区的配置信息更新后，辅助信令包括更新后的邻小区的配置信息。具体地，在邻小区的配置信息更新后，能够得到更新后的邻小区的配置信息，为了保证终端设备能够更准确使用配置信息进行干扰消除，需要再次发送辅助信令，此时辅助信令中直接包括更新后的邻小区的配置信息。例如，若更新前的邻小区的配置信息为邻小区的配置信息A，那么终端网络向终端设备发送的辅助信令会包括邻小区的配置信息A。基于此，若更新后的邻小区的配置信息为邻小区的配置信息B，那么终端网络向终端设备发送的辅助信令包括更新后的邻小区的配置信息(邻小区的配置信息B)。
在该实施方式中，在邻小区的配置信息更新后，重新发送辅助信令能够保证终端设备能够更准确使用配置信息进行干扰消除，提升终端设备进行干扰消除的准确性以及可靠性。
在本申请的一种可选实施方式中，辅助信令包括多个邻小区的配置信息。
在该实施方式中，由于辅助信令包括多个邻小区的配置信息，因此对所有邻小区对服务小区造成干扰的RE位置进行干扰测量，从中选择对服务小区干扰较强的邻小区对服务小区造成干扰的RE位置，并且在这些位置会上进行干扰消除，在保证对干扰较强的RE进行干扰消除的基础上。避免了在干扰较弱的RE位置进行干扰消除的资源消耗，由此提升干扰消除的可靠性，并且降低干扰消除的资源消耗。
在本申请的一种可选实施方式中，在终端设备不向服务小区的网络设备发送第一指示信息的场景下，网络设备通过广播方式向终端设备发送辅助信令，该辅助信令包括邻小区的配置信息，邻小区的配置信息包括CSI-RS配置信息，TRS配置信息以及SCS配置信息。
在该实施方式中，由于终端设备不向服务小区的网络设备发送第一指示信息，为了保证服务小区内所有的终端设备均能进行干扰消除，会将CSI-RS配置信息，TRS配置信息以及SCS配置信息均下发至所有终端设备，因此无论终端设备支持CSI-RS-IC以及TRS-IC中任意一种或多种消除方式，均可以通过邻小区的配置信息进行干扰消除，从而提升干扰消除的可靠性。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)。随着通信系统的不断发展，本申请的技术方案可应用于第五代(5th generation，5G)系统或新无线(new radio，NR)，还可应用于未来网络，如6G系统甚至未来系统；或者还可用于设备到设备(device to device，D2D)系统，机器到机器(machine to machine，M2M)系统等等。
应理解，该通信系统中的网络设备可以是任意一种具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网 络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站(Base Station)基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，无线保真(Wireless Fidelity，WIFI)系统中的接入点(Access Point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(TRP)等。具体地，前述基站即公用移动通信基站，是移动设备接入互联网的接口设备，也是无线电台站的一种形式，是指在一定的无线电覆盖区中，通过移动通信交换中心，与移动电话终端之间进行信息传递的无线电收发信电台。
其次，网络设备还可以为5G、6G甚至未来系统中使用的设备，如NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)，或微微基站(Picocell)，或毫微微基站(Femtocell)，或，车联网(vehicle to everything，V2X)或者智能驾驶场景中的路侧单元(road side unit，RSU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)层，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层(physical layer，PHY)的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
再次，本申请公开的实施例中，服务小区和邻小区可以是5G NR基站对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，在此不做限制。
本申请公开的实施例中，用于实现网络设备的功能的装置可以是网络设备；也可以是能够支持网络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网络设备中。
还应理解，该通信系统中的终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety) 中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、前述的V2X车联网中的无线终端或无线终端类型的RSU等等。本申请的实施例对应用场景不做限定。
此外，为了便于理解，这里对本申请实施例涉及到的一些术语或概念进行解释。
一、UE能力。
UE能力指的是UE能够支持某种特性的能力。UE能力有很多种，在实际应用中，UE会对标准上定义的选择性支持的特性上报UE能力，用于通知服务小区的基站自己是否支持某一个或几个特性。
二、干扰消除(interference cancellation，IC)。
干扰消除指的是UE对受到的干扰进行的一类消除操作。
其次，为了进一步理解本申请实施例，再作出以下几点说明。
第一，在本申请中，为便于描述，在涉及编号时，可以从0开始连续编号。
应理解，上文所述均为便于描述本申请实施例提供的技术方案而进行的设置，而并非用于限制本申请的范围。
第二，在下文示出的实施例中，对于一种技术特征，通过“第一”、“第二”、“第三”等区分该种技术特征中的技术特征，该“第一”、“第二”、“第三”描述的技术特征间无先后顺序或者大小顺序。
第三，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b和c中的至少一项(个)，可以表示：a，或，b，或，c，或，a和b，或，a和c，或，b和c，或，a、b和c。其中a、b和c分别可以是单个，也可以是多个。
第四，本申请公开的实施例将围绕包括多个设备、组件、模块等的系统来呈现本申请的各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
第五，本申请公开的实施例中，“的(of)”，“相应的(relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
随着通信技术的发展，在现网部署中，当邻小区的用户数据负载较低时，服务小区常常使用高阶调制。基于此，邻小区的CSI-RS以及TRS，会与本小区发送的PDSCH数据或TRS所占用的RE相互碰撞，导致服务小区的TRS或PDSCH在该RE位置上解码失败。又由于发送选用高阶调制，所以个别RE的污染对性能的影响很大。例如，请参阅图1，图1为本申请实施例中服务小区受到邻小区的干扰的一个场景示意图，如图1所示，图1中(A)图示出的为服务小区的TRS受到邻小区TRS的干扰的场景，在该场景下，服务小区的TRS受到 邻小区TRS的碰撞，导致服务小区时频估计跟踪不精确，影响信道参数估计，降低PDSCH解调性能。其次，图1中(B)图示出的为服务小区PDSCH受到邻小区TRS的干扰的场景，在该场景下，服务小区的PDSCH受到邻小区TRS碰撞，若UE的一个RE受到干扰就会显著影响高阶调制解调性能，导致整体性能下降。再次，其次，图1中(C)图示出的为服务小区PDSCH受到邻小区CSI-RS的干扰的场景，在该场景下，服务小区的PDSCH受到邻小区CSI-RS的碰撞，与图1中(B)图示出场景类似，若UE的一个RE受到干扰就会导致整体解调性能的下降。
由此可知，邻小区的TRS，CSI-RS，会与服务小区发送的PDSCH数据或TRS所占用的RE相互碰撞，导致服务小区的TRS或PDSCH在该RE位置上解码失败。由于发送选用高阶调制，所以RE的污染对性能的影响非常巨大，导致性能显著降低，包括时频偏跟踪、估计的误差增大，误码率增大，吞吐量降低等问题。目前，为了解决图1中服务小区受到邻小区的干扰的场景中所带来的性能降低的问题，能够对于邻小区发送导频的具体RE位置会通过做速率匹配来避免资源的重叠所带来的碰撞干扰。具体为，服务小区的基站根据速率匹配的图案将对应位置的RE空出来，且不发送PDSCH数据，由于通过速率匹配将部分邻区所用的TRS或CSI-RS位置空了出来而不发送PDSCH数据，所以在这些对应位置上不会有来自邻区导频的对服务小区下行PDSCH数据的干扰。然而，由于速率匹配避免干扰，会浪费许多时频资源，且速率匹配使得邻区CSI-RS或TRS的位置上也无法发送服务小区PDSCH数据，从而降低频谱利用率。
为了解决上述问题，本申请实施例提供了一种干扰处理的方法，相关装置以及设备，能够在CSI-RS或TRS的RE位置上进行干扰消除，且提升频谱利用率。为了便于理解，首先对本申请实施例所使用的通信系统的系统架构进行描述。本申请可以通过网络设备以及一个或多个终端设备组成一个通信系统，基于此，图2为本申请实施例中系统框架的一个示意图，如图2所示，网络设备1，网络设备2与终端设备1到终端设备3组成一个通信系统，网络设备1为服务小区的网络设备，网络设备2为邻小区的网络设备。在该通信系统中，终端设备1到终端设备3能够向网络设备1发送上行数据，网络设备1则可以接收终端设备1到终端设备3的上行数据，而终端设备1到终端设备3还能够发送PDSCH数据。此外，网络设备2的TRS与CSI-RS还可能对终端设备1到终端设备3造成干扰。应理解，在实际应用中，还可以为多个邻小区的网络设备，或者更多终端设备，因此图2中示出的终端设备与网络设备的数量不应理解为本申请实施例的限定。
下面将从方法的角度对本申请实施例提供的方案进行介绍，基于此前述对UE能力以及干扰消除的介绍可知，每个终端设备拥有的UE能力不同，也就是每个终端设备拥有的干扰消除的能力不同，在进行干扰处理的过程中，每个终端设备所有能够执行的干扰消除的操作也不同。因此，在进行干扰处理时，终端设备可以先向当前上报该终端设备进行服务的服务小区的网络设备的关于干扰消除的UE能力，即能够进行的干扰消除的操作，或者，终端设备也可以不上报关于干扰消除的UE能力。为了进一步地对本方案进行理解，下面分别对终端设备不上报关于干扰消除的UE能力，以及上报关于干扰消除的UE能力的不同情况进行介绍。
一、不上报关于干扰消除的UE能力。
在终端设备不上报关于干扰消除的UE能力的情况下，由于终端设备对邻小区的干扰进行消除时，具体需要根据邻小区的相关配置信息进行干扰消除的操作，该配置信息是需要为该终端设备提供的服务的服务小区的网络设备下发的，基于此，配置信息可以为网络设备直接发送的与服务小区相邻的全部邻小区的相关配置信息，或者，网络设备以每个与服务小区相邻的邻小区为单位，每个邻小区的配置信息中分别包括的邻小区的相关配置信息。为了便于理解，下面分别对上述两种情况进行介绍。
(1)不以邻小区为单位
请参阅图3，图3为本申请实施例中干扰处理的方法一个交互流程示意图，如图3所示，在终端设备不上报关于干扰消除的UE能力，且不以邻小区为单位发送配置信息的情况下，干扰处理的方法具体包括如下步骤。
步骤S301、终端设备接收网络设备发送的辅助信令，辅助信令包括邻小区的配置信息，邻小区的配置信息包括CSI-RS配置信息，TRS配置信息以及SCS配置信息。
本实施例中，终端设备接收网络设备发送的辅助信令，辅助信令具体为无线资源控制(radio resource control，RRC)信令。该辅助信令包括邻小区的配置信息，邻小区的配置信息包括参考信号配置信息以及子载波间隔(subcarrier spacing，SCS)配置信息。且本实施例中所描述的网络设备为服务小区的网络设备，而服务小区是对终端设备进行服务的小区，那么邻小区即为与服务小区相邻的小区。具体地，终端设备接收服务小区的网络设备通过广播方式发送的辅助信令。
具体地，由于终端设备并未上报关于干扰消除的UE能力，为了保证终端设备能够对CSI-RS的干扰或TRS的的干扰进行消除，因此参考信号配置信息具体包括CSI-RS配置信息，TRS配置信息。即此时网络设备向终端设备的邻小区的配置信息包括CSI-RS配置信息，TRS配置信息以及SCS配置信息。
可选地，当邻小区的配置信息更新后，再次发送的辅助信令包括增量式更新后的邻小区的配置信息。由于当网络设备确定邻小区的配置信息更新后，网络设备能够得到更新后的邻小区的配置信息。为了保证终端设备能够更准确使用配置信息进行干扰消除，此时网络设备会再次发送辅助信令，使得终端设备能够接收到最新的配置信息。基于此，为了减少信息传输的资源消耗，此时辅助信令中并不包括更新后的邻小区的配置信息，而是包括将更新后的邻小区的配置信息与更新前的邻小区的配置信息之间，进行更新的那部分配置信息(即增量式更新后的邻小区的配置信息)。
其中，增量式更新就是在版本更新时，不重新加载配置信息，只需要加载进行更新的部分配置信息，然后将进行更新的部分配置信息合并到更新前的配置信息上，这时候得到的就是更新后的配置信息，而所加载的进行更新的部分配置信息即为本实施例中所描述的增量式更新后的邻小区的配置信息。示例性地，若更新前的邻小区的配置信息为邻小区的配置信息A，那么在配置信息更新前，终端设备所接收到的辅助信令会包括邻小区的配置信息A。基于此，若更新后的邻小区的配置信息为邻小区的配置信息B，终端设备所接收到的辅助信令包括增量式更新后的邻小区的配置信息(邻小区的配置信息B-邻小区的配置信 息A)。前述示例仅用于理解本方案，具体增量式更新后的邻小区的配置信息需要根据实际情况灵活确定。
具体地，参考信号配置信息中CSI-RS配置信息具体包括CSI-RS的资源位置信息、CSI-RS的序列信息以及CSI-RS的功率信息。其中，CSI-RS的资源位置信息具体包括但不限于CSI-RS的频域位置、天线端口数、周期、偏移、密度以及码分复用类型(code division multiplexing type，CDM type)。CSI-RS的序列信息具体包括但不限于扰码标识(identity，ID)、时隙位置以及正交频分复用(orthogonal frequency division multiplexing，OFDM)符号位置。CSI-RS的功率信息具体包括CSI-RS上的功率分配信息。同理可知，参考信号配置信息中TRS配置信息具体包括TRS的资源位置信息、TRS的序列信息以及TRS的功率信息。其中，TRS的资源位置信息具体包括但不限于TRS的频域位置、天线端口数、周期、偏移、密度以及CDM type。TRS的序列信息具体包括但不限于扰码ID、时隙位置以及OFDM符号位置。TRS的功率信息具体包括TRS上的功率分配信息。
步骤S302、终端设备根据参考信号配置信息确定第一位置。
本实施例中，由于在步骤S301中，终端设备所接收到的辅助信令所包括的邻小区的配置信息中包括参考信号配置信息，因此终端设备能够根据参考信号配置信息确定第一位置，第一位置为邻小区对服务小区造成干扰的资源元素RE位置。
具体地，通过步骤S301可知，参考信号配置信息具体包括CSI-RS配置信息以及TRS配置信息，且CSI-RS配置信息具体包括CSI-RS的资源位置信息、CSI-RS的序列信息以及CSI-RS的功率信息，TRS配置信息具体包括TRS的资源位置信息、TRS的序列信息以及TRS的功率信息。
基于此，终端设备能够获取CSI-RS的资源位置信息中的CSI-RS的频域位置。并获取CSI-RS的资源位置信息中的周期以及偏移，以及获取CSI-RS的序列信息中的时隙位置以及OFDM符号位置，终端设备基于周期，偏移，时隙位置以及OFDM符号位置进行计算，能够得到CSI-RS的时域位置。基于此，终端设备根据获取得到的CSI-RS的频域位置以及计算得到的CSI-RS的时域位置进行计算，能够确定CSI-RS的资源元素(resource element，RE)位置，该CSI-RS的RE位置即为邻小区的CSI-RS对服务小区造成干扰的RE位置。
同理可知，终端设备能够获取TRS的资源位置信息中的TRS的频域位置。并获取TRS的资源位置信息中的周期以及偏移，以及获取TRS的序列信息中的时隙位置以及OFDM符号位置，终端设备基于周期，偏移，时隙位置以及OFDM符号位置进行计算，能够得到TRS的时域位置。基于此，终端设备根据获取得到的TRS的频域位置以及计算得到的TRS的时域位置进行计算，能够确定TRS的RE位置，该TRS的RE位置即为邻小区的TRS对服务小区造成干扰的RE位置。
由此可知，终端设备能够根据CSI-RS配置信息以及TRS配置信息，通过上述方式确定第一位置，且该第一位置包括CSI-RS的RE位置与TRS的RE位置。即终端设备能够确定邻小区的CSI-RS对服务小区造成干扰的RE位置，以及邻小区的TRS对服务小区造成干扰的RE位置。应理解，若服务器小区仅有一个相邻的邻小区，那么可以得到该邻小区的第一位置，若服务小区有多个相邻的邻小区，那么可以得到每个邻小区对应的第一位置，即每个 邻小区中CSI-RS的RE位置与TRS的RE位置。具体此处不对第一位置的具体数量进行限定，具体数量与邻小区的数量一致即可。
在实际应用中，在服务小区有多个相邻的邻小区的场景下，每个邻小区对服务小区的干扰强度是不同的，因此为了使得终端设备能够消除较强的干扰，还可以对所确定的邻小区的CSI-RS对服务小区造成干扰的RE位置，以及邻小区的TRS对服务小区造成干扰的RE位置进行选择。
具体地，终端设备通过前述类似方式确定邻小区的CSI-RS对服务小区造成干扰的RE位置，以及邻小区的TRS对服务小区造成干扰的RE位置，此时将邻小区的CSI-RS对服务小区造成干扰的RE位置，以及邻小区的TRS对服务小区造成干扰的RE位置定义为第二位置。然后对多个邻小区的第二位置的干扰强度进行测量，得到多个待处理测量结果，该待处理测量结果与邻小区的第二位置一一对应。然后通过不同的方式在多个待处理测量结果确定，并且将目标测量结果对应的邻小区的第二位置确定为第一位置。应理解，目标测量结果可以为一个或多个，但目标测量结果的数量是小于待处理测量结果的数量的，目标测量结果的具体数量本实施例中不做限定。
本实施例中可以通过两种不同的方式确定至少一个目标测量结果，第一种方式为通过预设数量阈值确定，第二种方式为通过预设百分比阈值确定，下面分别介绍本实施例中的两种方式。
第一种方式，通过预设数量阈值确定目标测量结果。该预设数量阈值为终端设备确定的具体数量。例如，预设数量阈值为2，那么能够确定目标测量结果的最大数量即为2，基于此，对多个待处理测量结果按照干扰程度的大小进行排序，将多个待处理测量结果中干扰程度的大小为前2个的待处理测量结果，或干扰程度的大小为第1个的待处理测量结果确定为目标测量结果。应理解，在不同的场景下，预设数量阈值是根据终端设备对邻小区的干扰强度通过进行实验和/或基于大量数据的统计所确定的。
第二种方式，通过预设百分比阈值确定目标测量结果。该预设百分比阈值为多个待处理测量结果中能够确定目标测量结果数量的最大百分比。例如，预设数量阈值为50％，且待处理测量结果的数量为10，那么目标测量结果的最大数量即为5，基于此，对10个待处理测量结果按照干扰程度的大小进行排序，将10个待处理测量结果中干扰程度的大小为前5个的待处理测量结果确定为目标测量结果。应理解，在不同的场景下，预设百分比阈值是根据终端设备对邻小区的干扰强度通过进行实验和/或基于大量数据的统计所确定的。
在一种可能的场景下，为了保证能够高效且准确的进行干扰消除，终端设备还能够设定干扰强度阈值，若多个待处理测量结果的干扰程度的大小均小于干扰强度阈值，则说明多个邻小区对服务小区的干扰较弱，此时可以选择暂时不进行干扰消除，即暂时不对第一位置进行确定，具体场景此处不做限定。由此能够避免了在干扰较弱的RE位置进行干扰消除的资源消耗，降低干扰消除的资源消耗。
步骤S303、终端设备根据SCS配置信息确定干扰消除处理方式。
本实施例中，由于在步骤S301中，终端设备所接收到的辅助信令所包括的邻小区的配置信息中包括SCS配置信息，基于此，终端设备能够根据SCS配置信息确定干扰消除处理 方式。
具体地，在5G NR场景下，不同小区配置的SCS可能不同，这就导致在服务小区对相邻小区带来的干扰进行消除时，处理方式有所不同，带来的复杂度也不同。5G NR中，频率范围1(frequency range 1，FR1)能够使用的SCS包括下面三种，分别为15kHz，30kHz以及60kHz，其次，FR2能够使用的SCS包括下面三种，分别为60kHz，120kHz，和240kHz。例如，在FR1的场景下，服务小区的SCS与邻小区的SCS是如下四种配置：(服务小区，邻小区)＝(15，15)，或，(服务小区，邻小区)＝(15，30)，或，(服务小区，邻小区)＝(30，15)，或，(服务小区，邻小区)＝(30，30)。
基于前述四种配置，在服务小区与邻小区的SCS相同，以及服务小区与邻小区的SCS不同的情况下，所涉及的处理方式不一样。例如，在服务小区的SCS与邻小区的SCS为(15，15)或(30，30)这种可能性下，此时可以确定处理方式中仅使用一个快速傅里叶变换(fast fourier transform，FFT)，其次，在服务小区的SCS与邻小区的SCS为(15，30)或(30，15)这种可能性下，此时可以确定处理方式中将使用两个FFT。应理解，前述示例仅用于理解本方案，具体干扰消除处理方式需要根据服务小区与邻小区的SCS配置信息确定，不应理解为本实施例的限定。
步骤S304、终端设备使用干扰消除处理方式在第一位置上进行干扰消除。
本实施例中，由于在步骤S302中，终端设备能够确定第一位置，且在步骤S303中，终端设备能够确定干扰消除处理方式，因此终端设备能够使用干扰消除处理方式在第一位置上进行干扰消除。由此完成对邻小区的CSI-RS对服务小区造成干扰的消除的操作，并且完成对邻小区的TRS对服务小区造成干扰的消除的操作。因此，采用步骤S301至步骤S304中所介绍的干扰处理的方法，能够消除CSI-RS和TRS的干扰，且不影响在CSI-RS或TRS上发送PDSCH数据，从而提升频谱利用率。
(2)以邻小区为单位
请参阅图4，图4为本申请实施例中干扰处理的方法另一交互流程示意图，如图4所示，在终端设备不上报关于干扰消除的UE能力，且以邻小区为单位发送配置信息的情况下，干扰处理的方法具体包括如下步骤。
步骤S401、终端设备接收网络设备发送的辅助信令，辅助信令包括邻小区的配置信息，邻小区的配置信息包括参考信号配置信息，SCS配置信息以及每个邻小区的小区标识。
本实施例中，终端设备接收网络设备发送的辅助信令，辅助信令具体为RRC信令。该辅助信令包括邻小区的配置信息，邻小区的配置信息包括参考信号配置信息，SCS配置信息以及每个邻小区的小区标识。且本实施例中所描述的网络设备以及邻小区与步骤S301中所介绍的类似，在此不再赘述。具体地，终端设备接收服务小区的网络设备通过广播方式发送的辅助信令。
具体地，由于终端设备并未上报关于干扰消除的UE能力，为了保证终端设备能够对CSI-RS的干扰或TRS的的干扰进行消除，因此参考信号配置信息具体包括CSI-RS配置信息以及TRS配置信息。其次为了能够让终端设备能够确定邻小区的配置信息具体来源于哪个邻小区，因此参考信号配置信息还需要包括每个邻小区的小区标识。即此时网络设备向 终端设备的邻小区的配置信息应该包括CSI-RS配置信息，TRS配置信息，SCS配置信息以及每个邻小区的小区标识，邻小区的小区标识指示邻小区的配置信息来源于邻小区。
示例性地，若与服务小区相邻的小区包括邻小区1，邻小区2以及邻小区3，而终端设备所接收到的辅助信令包括CSI-RS配置信息1，TRS配置信息1以及SCS配置信息1，CSI-RS配置信息2，TRS配置信息2以及SCS配置信息2，以及CSI-RS配置信息3，TRS配置信息3以及SCS配置信息3，且还包括小区标识1，小区标识2以及小区标识3。基于此，若小区标识1指示CSI-RS配置信息1，TRS配置信息1以及SCS配置信息1来源于邻小区1，小区标识2指示CSI-RS配置信息2，TRS配置信息2以及SCS配置信息2来源于邻小区2，小区标识3指示CSI-RS配置信息3，TRS配置信息3以及SCS配置信息3来源于邻小区3，那么终端设备能够根据小区标识确定，每个不同配置信息来源于哪个邻小区，因此后续所确定的第一位置也能够确定具体干扰来自于哪个邻小区，由此提升干扰消除的可靠性以及准确度。
可选地，当邻小区的配置信息更新后，再次发送的辅助信令包括增量式更新后的邻小区的配置信息以及小区标识。应理解，每个小区的小区标识不会因为邻小区的配置信息更新而更新，即每个小区的小区标识是预设固定的。为了保证终端设备能够更准确使用配置信息进行干扰消除，此时网络设备会再次发送辅助信令，使得终端设备能够接收到最新的配置信息。具体发送增量式更新后的邻小区的配置信息的方式与步骤S301类似，在此不再赘述。
具体地，邻小区的配置信息中CSI-RS配置信息具体包括CSI-RS的资源位置信息、CSI-RS的序列信息以及CSI-RS的功率信息。且邻小区的配置信息中TRS配置信息具体包括TRS的资源位置信息、TRS的序列信息以及TRS的功率信息。具体信息与步骤S301中介绍的类似，在此不再赘述。
步骤S402、终端设备根据参考信号配置信息确定第一位置。
本实施例中，终端设备根据参考信号配置信息确定第一位置的方式与步骤S302类似，在此不再赘述。
基于此，终端设备还能够根据小区标识确定第一位置为哪个邻小区的RE位置。为了便于理解，以步骤S401所示例的配置信息作为示例进行介绍，终端设备基于与步骤S302类似的方式，通过CSI-RS配置信息1与TRS配置信息1确定第一位置1，同理可知，终端设备通过CSI-RS配置信息2与TRS配置信息2确定第一位置2，以及通过CSI-RS配置信息3与TRS配置信息3确定第一位置3。由于配置信息中还携带有小区标识，因此终端设备可以进一步地确定第一位置1为邻小区1的CSI-RS的RE位置以及TRS的RE位置，同理可知，第一位置2为邻小区2的CSI-RS的RE位置以及TRS的RE位置，第一位置3为邻小区3的CSI-RS的RE位置以及TRS的RE位置。
步骤S403、终端设备根据SCS配置信息确定干扰消除处理方式。
本实施例中，终端设备根据SCS配置信息确定干扰消除处理方式步骤的方式与步骤S303类似，在此不再赘述。
基于此，终端设备还能够根据小区标识确定每个小区的具体干扰消除处理方式。为了 便于理解，再次以步骤S401所示例的配置信息作为示例进行介绍，终端设备基于与步骤S303类似的方式，通过SCS配置信息1确定干扰消除处理方式1，同理可知，终端设备通过SCS配置信息2确定干扰消除处理方式2，以及通过SCS配置信息3确定干扰消除处理方式3。由于配置信息中还携带有小区标识，因此终端设备可以进一步地确定干扰消除处理方式1为对邻小区1采用的干扰消除处理方式，同理可知，干扰消除处理方式2为对邻小区2采用的干扰消除处理方式，干扰消除处理方式3为对邻小区3采用的干扰消除处理方式。应理解，对不同邻小区采用的干扰消除处理方式可以相同也可以不同，具体此处不做限定。
步骤S404、终端设备使用干扰消除处理方式在第一位置上进行干扰消除。
本实施例中，终端设备使用干扰消除处理方式在第一位置上进行干扰消除的方式与步骤S304类似，在此不再赘述。
为了便于理解，再次以步骤S401至步骤S403所示例的配置信息作为示例进行介绍，终端设备使用干扰消除处理方式1在第一位置上1进行干扰消除，从而完成对邻小区1的CSI-RS以及TRE带来的干扰。同理可知，使用干扰消除处理方式2在第一位置上2进行干扰消除，从而完成对邻小区2的CSI-RS以及TRE带来的干扰。其次，使用干扰消除处理方式3在第一位置上3进行干扰消除，从而完成对邻小区3的CSI-RS以及TRE带来的干扰。使得终端设备能够更为准确且高效的进行干扰消除，从而提升干扰消除的效率。
二、上报关于干扰消除的UE能力。
在终端设备上报关于干扰消除的UE能力的情况下，网络设备会根据终端设备上报的关于干扰消除的UE能力，发送终端设备所支持的干扰消除方式对应的配置信息。基于此，配置信息可以为网络设备直接发送终端设备所支持的干扰消除方式对应的配置信息，或者，网络设备以每个与服务小区相邻的邻小区为单位，每个邻小区的配置信息中分别包括邻小区的终端设备所支持的干扰消除方式对应的配置信息。为了便于理解，下面分别对上述两种情况进行介绍。
(1)不以邻小区为单位
请参阅图5，图5为本申请实施例中干扰处理的方法一个交互流程示意图，如图5所示，在终端设备上报关于干扰消除的UE能力，且不以邻小区为单位发送配置信息的情况下，干扰处理的方法具体包括如下步骤。
步骤S501、终端设备向网络设备发送第一指示信息。
本实施例中，终端设备向网络设备发送第一指示信息，该第一指示信息用于指示终端设备关于干扰消除的UE能力，即第一指示信息能够指示终端设备支持进行信道状态信息参考信号干扰消除CSI-RS-IC，或，指示终端设备支持进行跟踪参考信号干扰消除TRS-IC，或，指示终端设备支持进行CSI-RS-IC以及TRS-IC。具体地，CSI-RS-IC为对第一干扰进行消除，第一干扰为邻小区的CSI-RS对服务小区数据的干扰。其次，TRS-IC为对第二干扰进行消除，第二干扰为邻小区的TRS对服务小区数据和/或TRS的干扰。
步骤S502、终端设备接收网络设备发送的辅助信令，辅助信令包括邻小区的配置信息，邻小区的配置信息包括参考信号配置信息以及SCS配置信息。
本实施例中，由于网络设备通过步骤S501能够接收到终端设备发送的用于指示终端设备关于干扰消除的UE能力的第一指示信息。因此基于该第一指示信息所指示的内容，网络设备会向终端设备发送符合终端设备关于干扰消除的UE能力的配置信息。因此终端设备接收网络设备发送的辅助信令，且具体辅助信令为RRC信令，且辅助信令包括邻小区的配置信息，此时邻小区的配置信息包括参考信号配置信息以及SCS配置信息，且参考信号配置信息具体包括CSI-RS配置信息以及TRS配置信息中至少一项。具体地，当邻小区的配置信息更新后，辅助信令包括增量式更新后的邻小区的配置信息以及每个邻小区的小区标识。本实施例中所描述的网络设备，邻小区以及增量式更新后与步骤S301中所介绍的类似，此处不再赘述。

本实施例中当邻小区的配置信息更新后，再次发送的辅助信令包括增量式更新后的邻小区的配置信息的具体方式与步骤S301类似，在此不再赘述。其次，CSI-RS配置信息与TRS配置信息具体包括内容也与步骤S301所介绍类似，在此不再赘述。
步骤S503、终端设备根据参考信号配置信息确定第一位置。
本实施例中，终端设备能够根据步骤S502所获取的参考信号配置信息确定第一位置。
具体地，当步骤S501中第一指示信息指示终端设备支持进行CSI-RS-IC，此时终端设备接收到的辅助信令包括邻小区的配置信息即包括CSI-RS配置信息。基于此，终端设备能够获取CSI-RS的资源位置信息中的CSI-RS的频域位置。并获取CSI-RS的资源位置信息中的周期以及偏移，以及获取CSI-RS的序列信息中的时隙位置以及OFDM符号位置，终端设备基于周期，偏移，时隙位置以及OFDM符号位置进行计算，能够得到CSI-RS的时域位置。基于此，终端设备根据获取得到的CSI-RS的频域位置以及计算得到的CSI-RS的时域位置进行计算，能够确定CSI-RS的RE位置，该CSI-RS的RE位置即为邻小区的CSI-RS对服务小区造成干扰的RE位置。此时第一位置为每个邻小区的CSI-RS的RE位置。
同理可知，当步骤S501中第一指示信息指示终端设备支持进行TRS-IC，此时终端设备接收到的辅助信令包括邻小区的配置信息即包括TRS配置信息。基于此，终端设备能够获取TRS的资源位置信息中的TRS的频域位置。并获取TRS的资源位置信息中的周期以及偏移，以及获取TRS的序列信息中的时隙位置以及OFDM符号位置，终端设备基于周期，偏移，时隙位置以及OFDM符号位置进行计算，能够得到TRS的时域位置。基于此，终端设备根据获取得到的TRS的频域位置以及计算得到的TRS的时域位置进行计算，能够确定TRS的资源元素RE位置，该TRS的RE位置即为邻小区的TRS对服务小区造成干扰的RE位置。此时第一位置为每个邻小区的TRS的RE位置。
再次，当步骤S501中第一指示信息指示终端设备支持进行CSI-RS-IC以及TRS-IC， 此时终端设备接收到的辅助信令包括邻小区的配置信息即包括CSI-RS配置信息以及TRS配置信息。基于此，终端设备能够根据前述两种方式确定CSI-RS的RE位置以及TRS的资源元素RE位置。此时第一位置为每个邻小区的CSI-RS的RE位置与TRS的RE位置。
其他相关步骤以及限定与步骤S302类似，在此不再赘述。

步骤S505、终端设备使用干扰消除处理方式在第一位置上进行干扰消除。
本实施例中，终端设备使用干扰消除处理方式在第一位置上进行干扰消除的方式与步骤S404类似，在此不再赘述。
(2)以邻小区为单位
请参阅图6，图6为本申请实施例中干扰处理的方法另一交互流程示意图，如图6所示，在终端设备上报关于干扰消除的UE能力，且以邻小区为单位发送配置信息的情况下，干扰处理的方法具体包括如下步骤。
步骤S601、终端设备向网络设备发送第一指示信息。
本实施例中，终端设备向网络设备发送第一指示信息与步骤S501类似，在此不再赘述。
步骤S602、终端设备接收网络设备发送的辅助信令，辅助信令包括邻小区的配置信息，邻小区的配置信息包括参考信号配置信息，SCS配置信息以及每个邻小区的小区标识。
本实施例中，终端设备接收网络设备发送的辅助信令，该辅助信令包括邻小区的配置信息。具体地，当邻小区的配置信息更新后，辅助信令包括增量式更新后的邻小区的配置信息以及每个邻小区的小区标识。本实施例中所描述的网络设备，邻小区以及增量式更新后与步骤S301中所介绍的类似，此处不再赘述。
由于终端设备已上报关于干扰消除的UE能力，为了保证终端设备能够对CSI-RS的干扰或TRS的的干扰进行消除，并且能够让终端设备能够确定邻小区的配置信息具体来源于哪个邻小区，此时网络设备向终端设备的邻小区的配置信息应该包括CSI-RS配置信息以及TRS配置信息中至少一项，SCS配置信息以及每个邻小区的小区标识，邻小区的小区标识指示邻小区的配置信息来源于邻小区。邻小区的配置信息具体包括的CSI-RS配置信息以及TRS配置信息与步骤S501中所介绍的类似，而邻小区的小区标识与步骤S401中所介绍的类似，在此也不再赘述。
步骤S603、终端设备根据参考信号配置信息确定第一位置。
本实施例中，终端设备根据参考信号配置信息确定第一位置的方式与步骤S503类似，在此不再赘述。
进一步地，由于本实施例中邻小区的配置信息还包括邻小区的小区标识，因此终端设备还能够根据小区标识确定第一位置为哪个邻小区的RE位置。为了便于理解，以邻小区包括邻小区1以及邻小区2作为示例进行说明，若第一指示信息指示终端设备支持进行TRS-IC，此时终端设备接收到的辅助信令包括邻小区的配置信息即包括TRS配置信息。且对应的邻小区1配置信息为TRS配置信息1，小区标识为“1”，邻小区2配置信息为TRS配置信息2， 小区标识为“2”。基于此，终端设备通过TRS配置信息1确定第一位置1，通过TRS配置信息2确定第一位置2，然后终端设备可以进一步地确定第一位置1为邻小区1的TRS的RE位置，第一位置2为邻小区2的TRS的RE位置。应理解，前述示例仅用于理解本方案，而不应理解为本方案的限定。
步骤S604、终端设备根据SCS配置信息确定干扰消除处理方式。
本实施例中，终端设备根据SCS配置信息确定干扰消除处理方式步骤的方式与步骤S403类似，在此不再赘述。
步骤S605、终端设备使用干扰消除处理方式在第一位置上进行干扰消除。
本实施例中，终端设备使用干扰消除处理方式在第一位置上进行干扰消除的方式与步骤S404类似，在此不再赘述。
在一种可选的实施方式中，图6的实施例中介绍了一种在终端设备上报关于干扰消除的UE能力，且以邻小区为单位发送配置信息的情况下，进行干扰处理的方法，然而在实际应用中，为了降低网络设备发送配置信息的资源消耗，以及在需要对多个邻小区进行选择时，提升终端设备干扰处理的效率，终端设备在向服务小区的网络设备发送第一指示信息之后，且接收服务小区的网络设备发送的辅助信令之前，还能够主动测量每个邻小区的干扰强度，并通过指示信息，将干扰强度较强的邻小区的小区标识发送给网络设备，使得网络设备仅发送干扰强度较强的邻小区的配置信息即可。基于此，下面对此种情况进行详细介绍，请参阅图7，图7为本申请实施例中干扰处理的方法另一交互流程示意图，如图7所示，干扰处理的方法具体包括如下步骤。

本实施例中，在服务器小区有多个邻小区的情况下，终端设备对多个邻小区的干扰强度进行测量后，得到多个邻小区对应的干扰强度测量结果，然后对多个邻小区对应的干扰强度测量结果，按照干扰强度从高到低排序，由此从多个邻小区对应的干扰强度测量结果中确定至少一个干扰强度测量结果，一个或多个干扰强度测量结果为多个干扰强度测量结果中干扰强度最强或者较强的结果，并且将所确定的干扰强度测量结果对应的邻小区确定为待处理小区。
示例性地，若服务器小区有6个邻小区，分别为邻小区1，邻小区2至邻小区6，终端设备对6个邻小区的干扰强度进行测量后，得到邻小区1对应的干扰强度测量结果1，邻小区2对应的干扰强度测量结果2，至邻小区6对应的干扰强度测量结果6。按照干扰强度测量结果反映的干扰强度从大到小排序，若干扰强度从大到小的具体顺序为干扰强度测量结果6，干扰强度测量结果4，干扰强度测量结果3，干扰强度测量结果1，干扰强度测量结果2以及干扰强度测量结果5。此时终端设备根具体情况能够确定干扰强度测量结果6以及干扰强度测量结果4的干扰较强，因此干扰强度测量结果6对应的邻小区6以及干扰强度测量结果4对应的邻小区4，被确定为待处理小区。应理解，被选择的干扰强度测量结果可以为一个或多个，但被选择的干扰强度测量结果小于所有邻小区对应的干扰强度测 量结果的数量，被选择的干扰强度测量结果本实施例中不做限定。
