摘要： A method and apparatus are described for obtaining port index information. In one scenario, downlink (DL) control information (DCI) is received that includes new data indicator (NDI). The NDI has a value indicating an antenna port for single-port transmission. In response to receiving the DCI, a single-port transmission associated with the indicated antenna port is received. The NDI may be associated with a disabled codeword and the DCI may include a second NDI. The DCI may be received over a physical downlink control channel (PDCCH). The DCI may include a resource block (RB) assignment information field (IF), a hybrid automatic repeat request (HARQ) process identity (ID) IF, a transmit power control (TPC) IF and, for each of a plurality of transport blocks, a modulation and coding scheme (MCS), an NDI and a redundancy version (RV).
