请参阅图2，图2示出了根据本公开一实施方式的端口配置方法的流程图。

在相关技术中，基站在对终端的端口进行配置时，是对协议中终端可能支持的所有层进行配置，例如，当协议中终端可能支持的最大传输层数为8，相关技术对1-8层全部进行配置，而没有考虑具体终端的能力，在这种情况下，基站通过DCI向基站发送目标端口选择参数将对应1-8层，将占用大量的DCI数据位，从而造成大量的信令开销，浪费了资源。
本公开通过对终端的端口进行适应性配置，可以降低信令开销。

其中，所述天线端口配置参数被所述终端用于选择与所述终端的传输能力适配的关联关系集合。
在一种可能的实施方式中，所述根据所述设备信息向所述终端发送所述天线端口配置参数及所述端口选择参数，包括：
