Example Embodiment

[0051] Example 1

[0052] The method for sending measurement reference signals provided in this example can solve the problem of insufficient SRS multiplexing capacity in the prior art.

[0053] The sending method of measurement reference signal provided in this example includes:

[0054] The base station triggers the user terminal to send the measurement reference signal, and sends configuration information for sending the measurement reference signal to the user terminal. The configuration information includes one or more of the following indication information: precoding enable indication information of the measurement reference signal, precoding information of the measurement reference signal, and the number of transmissions of the measurement reference signal. The precoding enable indication information of the measurement reference signal in this example is used to indicate whether the measurement reference signal is to be precoded.

[0055] The user terminal sends the measureme...

[0062] Example 2

[0063] The method for sending measurement reference signals provided in this example is implemented by a system including a base station and a user terminal. among them,

[0064] The base station is used to trigger the user terminal to send the measurement reference signal, and to send the configuration information of the measurement reference signal to the user terminal;

[0065] The foregoing configuration information includes one or more of the following indication information: precoding enable indication information of the measurement reference signal, precoding information of the measurement reference signal, and the number of transmissions of the measurement reference signal.

[0066] The user terminal is used to send the measurement reference signal to the base station according to the obtained configuration information.

[0067] The base station sends the configuration information for sending the measurement reference signal to the user terminal according to ...

Example Embodiment

[0075] Example 3

[0076] In this example, the base station is used to trigger the user terminal to send the SRS, and to send the configuration information of the measurement reference signal to the user terminal; the configuration information includes one or more of the following indication information: precoding enable indication of the measurement reference signal Information, measurement reference signal precoding information, measurement reference signal transmission times.

[0077] Such as Figure 5 As shown in the figure, 401 is a macro base station, 402 is RRH0, and 403 is RRH1. In the CoMP system, the base station sends configuration information for sending measurement reference signals to the user terminal, where the configuration precoding is enabled.

[0078] The user terminal sends precoded measurement reference signals to RRH0 and RRH1 according to the obtained configuration information. The macro base station compares the strength of the measurement reference signal r...

Abstract

The invention provides a method and a system for sending a measuring reference signal. The method comprises the following steps: issuing configuration information sending a survey reference signal (SRS) to a user by a base station, wherein the configuration information comprises precoding enabling indication information used for indicting whether the SRS is precoded or not; receiving configuration information by a user terminal; when the precoding enabling indication information indicates and enables, precoding the SRS to be sent and sending a precoded SRS to the base station by the user terminal; and when the precoding enabling indication information does not indicate and enable, sending the SRS which is not precoded to the base station. According to the technical means provided by the invention, the technical problems of insufficient user multiplexing capacity of the SRS in the relevant technology is solved so as to save SRS resource and effectively improve the SRS resource use rate, thereby improving the user multiplexing capacity of the SRS.
