Abstract

The present invention provides a method, device, terminal, base station and communication equipment for sending a sounding reference signal. The sending method includes: obtaining sending configuration information for sending a sounding reference signal SRS; the sending configuration information is used to indicate whether the terminal is allowed to send part of the configured ports on an orthogonal frequency division multiplexing OFDM symbol The SRS2. By adopting the method of the present invention, the terminal can obtain transmission configuration information in advance, and according to the transmission configuration information, only SRSs of some ports can be transmitted on one OFDM symbol, so as to avoid wasting power due to transmission of SRSs of ports with poor channel conditions, thereby To a certain extent, the SRS transmission power of ports with better channel conditions is increased, and the channel estimation performance is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device, terminal, base station and communication equipment for sending a sounding reference signal. Background technique [0002] In the 3.5GHz new radio NR, since the terminal has multiple transmitting antennas, it is necessary to support multi-port SRS transmission. The current standardization supports the transmission of SRSs of multiple ports on consecutive N OFDM symbols and the simultaneous transmission of SRSs of multiple ports on one OFDM symbol. [0003] In practical applications, for the way that a terminal UE simultaneously transmits SRSs of multiple ports on one OFDM symbol, since there are situations where some ports correspond to better channel conditions and some ports correspond to poorer channel conditions, for example, for edge UEs, the The situation is more common. In this case, if the UE still uses the SRS of multiple ports to...
