A method for identifying resources of new wireless physical downlink control channels preempt by ultrahigh reliable low delay communication

摘要

A method and system for detecting a PDCCH (physical downlink control channel) of embB (enhanced mobile mobile broadband) under the presence of a user in urllc (ultra reliable low delay communication) is disclosed.The embB WTRU (wireless transmit / receive unit) may receive the embB corset configuration for correspet, which includes a PDCCH preemptive indicator.If the PDCCH preemption is valid based on the PDCCH preemption indicator, the embB WTRU By comparing the channel estimates for each reg (resource element group) bundle in the embB coreset, it is possible to identify and eliminate preempted reg in embB coreset.WTRU may detect the PDCCH by performing channel estimation based on the remaining reg in embB coreset and performing blind decoding on the remaining reg in embB coreset based on the received signal.
