Abstract: Methods and devices are disclosed to configure a wireless transmit receive unit (WTRU) with multiple physical downlink control channel (PDCCH) control resource sets (CORESETs) including at least a first PDCCH CORESET identifying first frequency resources of a downlink (DL) bandwidth part (BWP) for detection of downlink control information (DCI) and a second PDCCH CORESET identifying second frequency resources of the DL BWP for detection of DCI. The WTRU monitors one or more search spaces linked to active PDCCH CORSETs for transmissions of DCI. On determination that an interferer may impact PDCCH resources, a network sends, and a WTRU receives, signaling to suspend monitoring of search spaces linked to one of the first PDCCH CORSET or the second PDCCH CORESET for a suspend time period. Upon expiration of the suspend time period or sending/receiving unsuspend signaling, the WTRU resumes monitoring search spaces linked to a previously suspended PDCCH CORESET.
