Title:
PUSCH OPPORTUNITY REPETITIONS FOR RACH PROCEDURE
Document Type and Number:
WIPO Patent Application WO/2021/109101
Kind Code:
A1
Abstract:
In an aspect, a UE identifies a set of RACH opportunities over which to transmit a preamble (e.g., a Msg-A preamble of a 2-Step PRACH procedure). The UE selects a preamble sequence group associated with a repetition level for an uplink message (e.g., a Msg-A payload of a 2-Step PRACH procedure). The UE transmits the preamble to a BS on the identified set of ROs. The BS identifies the repetition level from the preamble. The UE transmits the uplink message to the set of POs in accordance with the repetition level.
