Abstract

The embodiment of the invention discloses an SRS (sounding reference signal) sending method, which relates to the technical field of wireless communication, and is designed for simplifying the signaling design of a communication system. The SRS sending method comprises the following steps: receiving control signaling from a base station, wherein a first field in the control signaling is used for indicating the operation of data transmission or SRS sending, a second field is used for indicating a frequency hopping mode used for data transmission or SRS sending, and a third field is used for indicating frequency band information during the process of transmitting data or SRS sending; according to the first field in the control signaling, determining whether the control signaling indicates an operation of SRS sending or data transmission; when the first field in the control signaling indicates an operation of SRS sending, according to the frequency band information indicated by the third field in the control signaling, sending a SRS in the frequency hopping mode indicated by the second field in the control signaling. The embodiment of the invention also provides an SRS receiving method corresponding to the SRS sending method, a base station and user equipment. The methods, base station and user equipment disclosed by the embodiment of the invention are used for SRS sending.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for sending and receiving sounding reference signals, a base station and user equipment. Background technique [0002] A Sounding Reference Signal (SRS, Sounding Reference Signal) is an uplink signal sent by a user equipment (UE, User Equipment) to implement uplink frequency domain scheduling. [0003] In the prior art, the method of sending the sounding reference signal is that the base station configures various parameters of the SRS for the user equipment; the base station sends the above-mentioned SRS parameters to the user equipment through dedicated signaling; The corresponding configuration of the SRS parameters sends the SRS to the base station, so that the base station can obtain uplink channel information through the SRS. [0004] However, the inventors found that the above method has at least the following problems: designing dedicated ...
