Wireless communication method of signaling CoMP states, and transmission point and user equipment therefor

摘要

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.

1. A wireless communication method of signaling coordinated multipoint (CoMP) states with one transport block (TB) enabled and one TB disabled, comprising:
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 CoMP states for the enabled TB in conjunction with a new data indicator (NDI) of the disabled TB; if an NDI of the enabled TB is equal to an untoggled value or the value of the 8-value indicator for the enabled TB is equal to 0, 1, 2, or 3, the UE using an NDI of the disabled TB to select a CoMP state from a first CoMP state and a second CoMP state, the untoggled value representing that the NIA of the enabled TB is not changed with respect to the NDI of the enabled TB in a previous transmission; and if the NDI of the enabled TB is equal to a toggled value and the value of the 8-value indicator is 4, 5, 6, or 7, the UE interpreting that a single layer and a third CoMP 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, the toggled value representing that the NDI of the enabled TB is changed with respect to the NDI of the enabled TB in the previous transmission.
