Abstract:
A method of performing downlink multiuser superposition transmission (MUST) with enhanced channel state information (CSI) feedback is proposed. When a user equipment (UE) reports CQI/SINR feedback for RI=RANK-2, the UE also reports a single beam CQI/SINR feedback for RI=RANK1. As a result, the scheduling base station can calculate the actual SINRs based on different MUST scenarios and thereby determining appropriate modulation and coding scheme (MCS) for the UE. Furthermore, if the granularity of the CQI table cannot reflect the high values of the single beam SINR, then a predefined scaling factor (0<β<1) known to both the base station and the UE may be applied.

Claim (Index 8):
A method comprising:\n measuring reference signals from a base station by a user equipment (UE) in a wireless communication network; transmitting channel state information (CSI) feedback to the base station, wherein the CSI feedback comprises a first channel quality indicator (CQI) associated with a first beam group and a second beam group and a second CQI associated with a single beam group; receiving a downlink transmission scheduled to the UE and a second co-channel UE over an allocated time-frequency radio resource using a multiuser transmission scheme; and applying a modulation and coding scheme (MCS) received from the base station, wherein the MCS is determined based on the CSI feedback and the multiuser transmission scheme.
