Abstract:
Disclosed are techniques for reporting a group delay-per-frequency lookup table for transmit and receive beams. In an aspect, a user equipment (UE) receives, from a transmission-reception point (TRP), a first downlink reference signal on at least one downlink reference signal resource using a downlink receive beam, transmits, to the TRP, an uplink reference signal on at least one uplink reference signal resource using an uplink transmit beam, determines a parameter representing a difference between a reception time of the first downlink reference signal and a transmission time of the uplink reference signal, transmit the parameter to a network entity, and transmits, to the network entity, a first lookup table or an identifier of the first lookup table, wherein the first lookup table represents per-frequency group delay information for the downlink receive beam and/or the uplink transmit beam.
