Summary:Methods and systems for detecting an enhanced massive mobile broadband (eMBB) physical downlink control channel (PDCCH) in the presence of for ultra-reliable low latency communication (URLLC) users are disclosed. A eMBB wireless transmit/receive unit (WTRU) may receive a eMBB control resource set (CORESET) configuration for a CORESET including a PDCCH preemption indicator. If PDCCH preemption is enabled based on the PDCCH preemption indicator, the eMBB WTRU may identify and remove preempted resource element groups (REGs) in the eMBB CORESET by comparing channel estimates for each REG bundle in the eMBB CORESET. The WTRU may perform channel estimation based on remaining REGs in the eMBB CORESET and detect the PDCCH by performing blind decoding, based on a received signal, on the remaining REGs in the eMBB CORESET.
