Abstract:
1. A method of transmitting a physical uplink shared channel (PUSCH) by a user equipment (UE) in a wireless communication system, the method comprising: transmitting a first codeword (CW) and a second CW to a base station (BS) via the PUSCH; receiving downlink control information (DCI) from the BS via a physical downlink control channel (PDCCH), the DCI including a first new data indicator (NDI) field corresponding to the first CW and a second NDI field corresponding to the second CW; and retransmitting at least the first CW or the second CW when at least the first NDI field or second NDI field has not been toggled, wherein the DCI further includes a first redundancy version (RV) field for the first CW, a second RV field for the second CW, a PUSCH resource block allocation field, a transmit power control (TPC) command for the PUSCH, a cyclic shift field for a demodulation reference signal (DMRS), a channel state information (CSI) request field, a precoding information field, an uplink index for time division duplexing (TDD) and a downlink allocation index for the TDD.
