    Abstract: An uplink reference signal transmission method is disclosed. User equipment receives first configuration information of a first uplink measurement reference signal and second configuration information of a second uplink measurement reference signal from a wireless network device. The first configuration information is used to configure a time-frequency resource of the first uplink measurement reference signal, and the second configuration information is used to configure a time-frequency resource of the second uplink measurement reference signal. The first uplink measurement reference signal is a zero-power uplink measurement reference signal, and the second uplink measurement reference signal is a non-zero-power uplink measurement reference signal. The user equipment sends, based on the first configuration information and the second configuration information, the second uplink measurement reference signal on a time-frequency resource, other than the time-frequency resource of the first uplink measurement reference signal, in the time-frequency resource of the second uplink measurement reference signal.

    Abstract: A CSI measurement method and apparatus are described. The CSI measuring includes obtaining CSI configuration information that includes first frequency-domain indication information and that is sent by a second network device, where the CSI configuration information instructs the first network device to perform a CSI measurement, and the first frequency-domain indication information indicates a frequency-domain location in which the first network device performs CSI measurement. The CSI measuring includes measuring, based on the CSI configuration information, a reference signal in the frequency-domain location indicated by the first frequency-domain indication information. The CSI measurement is sent to a network device, so that a reference signal in a specific frequency-domain location in channel bandwidth is measured.

    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.
