Embodiment Construction

[0053] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0054] image 3 is a flowchart of a method for sending indication information according to an embodiment of the present invention. Such as image 3 As shown, the method mainly includes the following processing:

[0055] Step S302: The base station configures indication information, wherein the indication information is used to indicate whether the user terminal sends multiple aperiodic SRSs to the base station;

[0056] Step S304: the base station sends the indication information to the user terminal.

[0057] In the related art, due to insufficient multiplexing capacity of the PDCCH for the user terminal, the user terminal cannot effectively transmit the aperiodic SRS. use as image 3 In the m...

Abstract

The invention discloses a method and a device for sending and receiving instruction information; and the method comprises the steps: configuring the instruction information by a base station, wherein the instruction information is used for indicating whether a user terminal sends an aperiodic sounding reference signal (SRS) into the base station for a plurality of times; and sending the instruction information into the user terminal by the base station. According to the technical scheme, the user terminal can more effectively send the aperiodic SRS, thus saving the physical downlink control channel (PDCCH) resource, and improving the timeliness and the accuracy of channel measurement of the base station.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending and receiving indication information. 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). In LTE, a 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 the configuration of higher layers (higher layers), which is also called configuration...
