Title:
JOINT MSG3 REPETITION FACTOR AND TPC INDICATION
Document Type and Number:
WIPO Patent Application WO/2021/114203
Kind Code:
A1
Abstract:
A user equipment (UE) operating as an NR-Light UE may repeat transmissions of uplink signals such as a random access (RA) message (Msg) 3 on a physical uplink shared channel (PUSCH) during a random access channel (RACH) procedure. The UE may receive a random access response (RAR) message including a RAR uplink (UL) grant. The UE may determine, based on a single bit of the RAR message, whether repetition of a RA Msg 3 is indicated. The UE may determine both of a repetition factor and a transmit power control (TPC) command for the RA Msg 3 based on a TPC field of the RAR UL grant. The UE may transmit the RA Msg 3 based on the repetition factor and the TPC command.
