example 1

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

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

[0054] The base station triggers the user terminal to send the measurement reference signal, and delivers 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 enabling indication information of the measurement reference signal, precoding information of the measurement reference signal, and sending times of the measurement reference signal. The precoding enabling indication information of the measurement reference signal in this example is used to indicate whether the measurement reference signal needs to be precoded.

[0055] The user terminal sends the measurement refe...

Embodiment 2

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

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

[0065] The above configuration information includes one or more of the following indication information: precoding enabling indication information of the measurement reference signal, precoding information of the measurement reference signal, and the number of times of sending the measurement reference signal.

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

[0067] The base station sends configuration information for sending measurement reference signals to the user terminal according to Figure 4 ...

Embodiment 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 above-mentioned measurement reference signal to the user terminal; the above-mentioned configuration information includes one or more of the following indication information: precoding enabling indication of the measurement reference signal information, precoding information of the measurement reference signal, and the number of transmission times of the measurement reference signal.

[0077] Such as Figure 5 As shown in the figure, 401 is the 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, wherein the configuration precoding is enabled.

[0078] The user terminal sends the precoded measurement reference signal to RRH0 and RRH1 according to the obtained configuration information. The macro base statio...

Abstract

The present invention provides a method and system for sending a measurement reference signal, wherein the above method includes: the base station sends configuration information for sending the measurement reference signal SRS to the user terminal, wherein the configuration information includes: used to indicate whether the SRS is Precoding enabling indication information for precoding; the user terminal receives configuration information; when the precoding enabling indication information indicates enablement, the user terminal performs precoding on the SRS to be sent, and sends the precoded SRS to the base station; When the precoding enabling indication information indicates that the precoding is not enabled, the SRS without precoding is sent to the base station. The above-mentioned technical means provided by the present invention solves technical problems such as insufficient SRS user multiplexing capacity in the related art, thereby realizing the purpose of saving SRS resources and improving the utilization rate of SRS resources more effectively, thereby achieving the purpose of increasing SRS user The effect of multiplexing capacity.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for sending a measurement reference signal (Sounding Reference Signal, SRS for short). Background technique [0002] The uplink physical channels of the Long Term Evolution (abbreviated as LTE) system include a physical random access channel (Physical Random Access Channel, abbreviated as PRACH), a physical uplink shared channel (Physical uplink shared channel, abbreviated as PUSCH), a physical uplink Control channel (Physical uplink control channel, PUCCH for short). [0003] In LTE, a physical downlink control channel PDCCH (Physical downlink control channel, PDCCH for short) is used to carry uplink and downlink scheduling information and uplink power control information. The base station (e-Node-B, referred to as eNB) can configure the user terminal (User Equipment, referred to as UE) through downlink control information, or the terminal equipment accepts...
