Title
(EN) METHOD FOR TRANSMITTING DATA USER EQUIPMENT UNIT AND NETWORK SIDE DEVICE
Abstract
(EN)
The invention relates to a method for transmitting data a user equipment unit and a network side device. The method comprises: receiving in a subframe first data and a first demodulation reference signal transmitted by a first network side device by means of n antenna ports and second data and a second demodulation reference signal transmitted by a second network side device by means of m antenna ports a time-frequency resource occupied by the first demodulation reference signal being different from a time-frequency resource occupied by the second demodulation reference signal time-frequency resources occupied by the first data and the second data being at least partially overlapping; and performing demodulation processing on the data according to the first demodulation reference signal and the second demodulation reference signal. The method for transmitting data the user equipment unit and the network side device of the invention can be applied in a non-quasi co-located scenario such that when multiple network side devices simultaneously transmit data to a user equipment unit in coordinated multiple points transmission/reception the quadrature of demodulation reference signals of the multiple network side devices can be guaranteed.
