RANDOM ACCESS CHANNEL TRANSMISSION AND DOWNLINK MONITORING BY A HALF-DUPLEX USER EQUIPMENT

Title:

RANDOM ACCESS CHANNEL TRANSMISSION AND DOWNLINK MONITORING BY A HALF-DUPLEX USER EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2023/010421

Kind Code:

A1

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for one or more downlink reference signals periodically transmitted from a base station during a first time period. The UE may determine that the UE is to participate in a random access procedure with the base station during a random access occasion, while the UE is operating in a half-duplex communication mode. The UE may identify that a first downlink reference signal is scheduled during a second time period that includes at least one random access occasion that corresponds with a reference signal for which the UE is configured to monitor, where the second time period is a subset of the first time period. As such, the UE may refrain from monitoring for the downlink reference signal during the time period in favor or proceeding with the random access procedure.
