Multi-carrier enhancements for improving reliability in URLLC-U

Abstract:

In various aspects, a base station and user equipment (UE) exchange an indication of UE capabilities and a monitoring schedule for the UE to monitor an integer M frequency band partitions for a predetermined signal. The base station performs one or more successful clear carrier assessments (CCAs) on an integer N frequency band partitions of the M frequency band partitions, wherein N<M, and maps one or more downlink transmissions to only the N frequency band partitions. Based on the mapping, the base station transmits the predetermined signal on only the N frequency band partitions, followed by a downlink signal during a transmission opportunity (TXOP). The UE cycles through the M frequency band partitions while monitoring for the predetermined signal according to the monitoring schedule, detects the predetermined signal on only the integer N frequency band partitions, and tunes to receive the downlink signal during the TXOP.
