COVERAGE ENHANCEMENT OF PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) TRANSMISSIONS

WIPO Patent Application WO/2024/065485

A1

Mechanisms are provided for a user equipment (UE) and a base station to support coverage enhancement of Physical Uplink Control Channel (PUCCH) transmissions by multiple repetitions to improve signal quality and reliability. A UE can be configured to determine, based on a reference signal measurement by the UE and a predetermined threshold, whether the UE is in a repetition enhancement mode to transmit a PUCCH transmission in a dedicated PUCCH resource set in a wireless system. In response to a determination of the UE in the repetition enhancement mode, the UE can transmit the PUCCH transmission in repetitions in the dedicated resource set according to a repetition enhancement configuration, which can be determined based on a system information (SI) received from the base station.
