Abstract:
The wireless communication comprises: transmitting downlink control information (DCI) from a transmission point to an UE for the enabled TB and the disabled TB, wherein the DCI comprises a 8-value indicator to indicate CoMP 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 CoMP 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 obtaining the information of whether the enabled TB is initial transmission or retransmission based on the NDI of the disabled TB.
