BEAM-SPECIFIC TIMING PRECOMPENSATION

Abstract:

Aspects relate to a user equipment that transmits an uplink transmission on a first receive beam of a first beam pair link and on a second receive beam of a second beam pair link. A base station receives the uplink transmission on a first transmit beam of the first beam pair link and a second transmit beam of the second beam pair link via first and second transmission and reception points associated with the base station. The base station transmits a downlink transmission on the first transmit beam with a first beam-specific timing precompensation and on the second transmit beam with a second beam-specific timing precompensation. The first beam-specific timing precompensation and the second beam-specific timing precompensation are based on a timing difference between the reception of the uplink transmission via the first TRP and via the second TRP. The user equipment receives the beam-specific timing precompensations.
