技术领域
本公开涉及通信技术领域，尤其涉及一种MU-MIMO场景下的终端用户间干扰处理方法及相关设备。
背景技术
5G NR基站在3.5GHz和更高频段普遍采用大规模MIMO部署，MU-MIMO因其对于网络整体吞吐量的提升以及可同时同频支持多用户传输等优点，是5G NR中广泛采用的传输方式。但在MU-MIMO场景下，存在终端用户之间的干扰，在Rel-16之前主要依靠网络侧设备(例如基站)对各用户信道信息进行调度，以避免此类干扰，但由于网络侧设备调度需要兼顾公平性、流量需求和实际用户位置等因素，实际传输中此类干扰对下行接收可靠性的影响依然较大。5G NR Rel-17引入了MMSE-IRC接收机用于抑制复用用户终端干扰。仿真结果表明，在网络侧设备采用正交预编码和随机预编码时，相比于传统的MMSE接收，E-MMSE-IRC/R-ML接收机利用更高的网络侧信息和较高的复杂度，可以预期获得更高的接收端可靠性，被纳入了3GPP Rel-18解调性能增强的研究内容中。
因而，如何提供一种根据终端的支持能力信息辅助终端进行MU-MIMO场景下终端用户间干扰处理方法，是目前亟待解决的技术问题。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本公开的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。
