Abstract: This application relates to a downlink control information indication method during coordinated multipoint transmission/reception in a wireless communications system. For a plurality of network side devices that send downlink data to user equipment on a same carrier and in a same subframe, downlink data transmission information used when the network side devices separately send the downlink data is indicated by using a plurality of pieces of downlink control information. Therefore, diversity transmission and/or multi-stream transmission in a multipoint coordination scenario are/is supported, and when the user equipment cannot normally receive downlink data sent by some network side devices because some downlink control information encounters an error, the user equipment may still receive, based on an indication of remaining downlink control information that encounters no error, downlink data sent by a network side device corresponding to the remaining downlink control information that encounters no error.

Abstract: This application relates to a data transmission method. The method includes: receiving, in a subframe, first data and first demodulation reference signal(s) that are sent by a first network side device by using n antenna port(s), and second data and second demodulation reference signal(s) that are sent by a second network side device by using m antenna port(s), where time-frequency resources occupied by the first demodulation reference signal(s) are different from time-frequency resources occupied by the second demodulation reference signal(s), and a time-frequency resource occupied by the first data and that occupied by the second data at least partly overlap; and performing demodulation processing on the data based on the first demodulation reference signal(s) and the second demodulation reference signal(s). The data transmission method may be applied to coordinated multipoint transmission/reception in which a plurality of network side devices that are not quasi-co-located simultaneously send data to user equipment.
