摘要:
Timing adjustments or frequency offsets that at least partially compensate for Doppler shift (e.g., due to distance of a satellite transmitter or relative speed of a terrestrial receiver) of a signal, physical channel, or resource during wireless transmission are configured. The characteristics compensated comprise one of resource element (RE) mapping, channel state information reference signal (CSI-RS) configuration, bandwidth part (BWP) configuration, or control resource set (CORESET) configuration. Information indicating the multiple configurations is transmitted from a base station (BS) to at least one user equipment (UE). The timing adjustments or frequency offsets are specifically configured for one UE, a group of UEs, or the UEs served by a single serving cell. Joint transmission from multiple cells/TRPs/spotbeams may involve partial/full subcarrier alignment.
