    摘要: At a UE, a rank indication is determined for multi-rank CSI feedback for a subband. The UE selects one of multiple combinations of first and second offset levels for the subband to indicate the determined rank indication. Each offset level is for one of two different codewords and denotes an offset between an MCS class reported in a subband CQI and an MCS class in a wideband CQI. The UE transmits one or more indications of the first and second offset levels. A base station receives the one or more indications, and determines the rank indication based on the one or more indications of the first and second offset levels. The base station schedules, based on the determined rank indication, data for transmission to the user equipment using one or multiple ranks.
