Embodiment Construction

[0085] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0086] Such as figure 1 As shown, it is one of the schematic flowcharts of the information sending method provided by the embodiment of the present invention, which is applied to a terminal. The implementation process of this method will be described in detail below with respect to this figure.

[0087] Step 101, acquire the adjustment information of the sending mode of the sounding reference signal.

[0088] Here, the manner of sending the sounding reference signal may include: sending the SRS based on the number of sending antennas, and sending the SRS based on the SRS period.

[0089] Specifically, sending SRS based on the number of sending antennas may include: using four antennas to send SRS in turn, using three antennas to send SRS in turn and on...

Abstract

The invention provides an information sending method and device, a terminal and a base station. The method comprises the following steps: acquiring sending mode adjustment information of a sounding reference signal; adjusting the number of transmitting antennas and / or the transmitting period of the sounding reference signal according to the transmitting mode adjusting information; and sending thesounding reference signal based on the adjusted number of the sending antennas and / or the sending period. According to the method disclosed in the invention, the sending mode of the sounding referencesignal can be flexibly adjusted according to the sending mode adjustment information, thereby achieving the effect of saving the electric quantity of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information sending method, device, terminal and base station. Background technique [0002] In the New Radio (NR) system, when the terminal is in the Non-Standalone (NSA) mode or the Standalone (SA) mode, the terminal antenna transmits and receives 1 transmit 4 receive or 2 transmit 4 receive . The agreement stipulates that in NSA mode, the sounding reference signal (Sounding Reference Signal, SRS) rotation method is to send SRS on 4 antennas in turn and only one antenna sends SRS at the same time; in SA mode, the SRS rotation method is The four antennas send SRS in turn and two antennas send SRS respectively at the same time, and the SRS information is distinguished by the port number. [0003] In a Multiple-Input Multiple-Output (MIMO) system using Nt transmitting antennas and Nr receiving antennas, the transmission channel can be represented by a matrix, a...
