The present disclosure discloses a wireless communication method of signaling Coordinated Multipoint (Co MP) sates, and a TP and a UE therefor. The wireless communication comprises: transmitting a downlink control information (DCI) from a transmission point (TP) to a user equipment (UE) for the enabled TB and the disabled TB, wherein the DCI comprises a 8-value indicator to indicate demodulation reference signal (DMRS) antenna ports, scrambling identity, number of layers, and Co MP states for the enabled TB in conjunction with the new data indicator (NDI) of the disabled TB; if the NDI of the enabled TB is untoggled or the value of the 8-value indicator for the enabled TB is equal to 0, 1, 2, or 3, the UE using the NDI of the disabled TB to select a Co MP state from a first CoMP state and a second CoMP state; and if the NDI of the enabled TB is toggled and the value of the 8-value indicator is 4, 5, 6, or 7, the UE interpreting that a single layer and a third Co MP state are configured for the enabled TB, and obtaining the information of whether the enabled TB is initial transmission or retransmission based on the NDI of the disabled TB. |
