Embodiment Construction
[0020] figure 1 It is a schematic flow chart of an embodiment of a power control method for a dedicated pilot in the present invention, including:
[0021] Step 11: Perform precoding processing on the dedicated pilot, the precoding matrix used in the precoding processing is the same as the precoding matrix used in the High Speed Physical Downlink Shared Channel (HS-PDSCH);
[0022] Among them, the dedicated pilot (dedicated pilot) is a concept relative to the common pilot (common pilot), the common pilot is the pilot sent to all UEs, and the dedicated pilot is the pilot sent to a certain UE , the UE can perform more accurate channel estimation and data demodulation according to the corresponding dedicated pilot. For the specific concept of the dedicated pilot, refer to the provisions in the Long Term Evolution (Long Term Evolution, LTE) protocol.
[0023] The precoding matrix adopted by the HS-PDSCH refers to the precoding matrix adopted by the data carried by the HS-PDSCH...
