Abstract

本申请实施例公开了一种通信方法，包括：接收第一配置信息，第一配置信息用于配置一个或多个CORESET，该一个或多个CORESET中至少一个CORESET配置有对应的组索引，该一个或多个CORESET不包含CORESET#0；确定CORESET#0的组索引；根据CORESET#0和/或所述一个或多个CORESET上传输的调度信息来接收该调度信息调度的PDSCH。由于终端设备已经确定了CORESET#0的组索引和/或所述一个或多个CORESET的组索引，可以利用组索引区分不同CORESET上传输的调度信息，从而可以接收不同CORESET上的调度信息调度的PDSCH，实现基于多PDCCH的传输方案。
