Title:
DEFAULT PATH LOSS REFERENCE SIGNAL IN UNIFIED TRANSMISSION CONFIGURATION INDICATION FRAMEWORK
Document Type and Number:
WIPO Patent Application WO/2022/147635
Kind Code:
A1
Abstract:
In a wireless network, a user equipment (UE) may be unable to determine a default path loss reference signal associated with an uplink transmission if the uplink transmission is transmitted using a beam associated with a transmission configuration indication (TCI) state and/or the uplink transmission and/or a physical downlink control channel (PDCCH) scheduling the uplink transmission is associated with a repetition configuration. In such cases, depending on a type associated with the uplink transmission, the UE may determine the default path loss reference signal based on the repetition configuration associated with the PDCCH and/or a TCI state for an uplink control channel or uplink reference signal. Accordingly, the UE may perform an uplink power control operation for the uplink transmission using the default path loss reference signal determined based on the repetition configuration associated with the PDCCH and/or the TCI state for the uplink control channel or uplink reference signal.
