Abstract

本申请提供了一种用于检测PDCCH的方法、装置和通信设备，包括：终端设备针对非授权频谱载波上配置的下行BWP中可用的子带，从多种CORESET配置中，确定第一CORESET配置，其中，所述CORESET配置中未限定频域资源绝对位置，所述可用的子带为网络设备执行LBT成功的子带；基于所述第一CORESET配置，所述终端设备，所述第一PDCCH为用于调度所述终端设备的PDCCH；基于确定的所述资源位置，所述终端设备检测所述第一PDCCH。本申请实施例提供的方法，通过对下行BWP中可用的子带，从多种未限定频域资源绝对位置的CORESET配置中，动态选择第一CORESET配置，以用于确定该可用的子带上检测PDCCH的资源位置，从而可以实现灵活选择CORESET配置，因此能够达到终端设备的盲检次数的最大化，并且可以提高PDCCH资源的利用率。
