Title:
UE TRIGGERED REPEATED (RE) TRANSMISSION OF MSG3 PUSCH
Document Type and Number:
WIPO Patent Application WO/2022/147810
Kind Code:
A1
Abstract:
Systems and method for providing support for indicating a request for coverage enhancement are disclosed. In embodiments, a UE indicates a request for coverage enhancement to a base station. The base station, in response to receiving the indication, applies coverage enhancement to subsequent communications between the UE and the base station. Indicating the request for coverage enhancement may include transmitting a physical random access channel (PRACH) message in a portion of a set of frequency domain resources granted to the UE for the transmission of the PRACH message, transmitting a demodulation reference signal in a first set of resource elements different than the standard set of resource elements, transmitting the DMRS using a first set of cyclic shifts different than the standard set of cyclic shifts, and/or scheduling and/or transmitting a sounding reference signal (SRS) as a substitute for the PRACH message.
