Embodiment Construction

[0064] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] Such as figure 1As shown, this embodiment provides an SRS sending method, which is applied to the first communication device, including:

[0066] Step S110: Send an SRS by using an SRS symbol, wherein the SRS symbol is a transmission symbol for transmitting the SRS; the frequency resources occupied by two adjacent SRS symbols in the time domain are at least partly the same; the two adjacent SRS symbols in the time domain For at least part of the same frequency resource in the SRS symbols, the same antenna port is used to send the SRS.

[0067] In this embodiment, the first communication device may be a user equipment (User Equipment, UE), and at this time, the SRS sent in the step S110 is an SRS sent uplink. The SRS is an uplink sounding reference signal, which can be used to detect uplink channel s...

Abstract

Embodiments of the invention disclose an SRS sending method, a phase difference processing method, communication equipment and a storage medium. The SRS sending method applied to the first communication equipment comprises that an SRS is sent via an SRS symbol which is used to transmit the SRS; at least part of frequency resource occupied by two SRS symbols in neighbor time domains is the same; and the part occupying the same frequency resource of the two SRS symbols in the neighbor time domains uses the same antenna port to send the SRS.

Description

technical field [0001] The present invention relates to a synchronization technology in the communication field, in particular to a sounding reference signal (Sounding Reference Signal, SRS) transmission method, a phase difference processing method, a communication device and a storage medium. Background technique [0002] The 5G system allows SRS to be sent on consecutive multiple symbols within one slot. The 5G system supports full-band access of low frequency and high frequency. In a high-band communication scenario, there will be a phase difference between multiple consecutive symbols that transmit SRS due to influences such as phase noise, and the phase difference will affect the accuracy of SRS detection. In the prior art, this phase difference is measured by sending a phase tracking signal for detecting the phase difference. However, in this way, the channel detection depends on the transmission of the phase tracking signal, which leads to problems such as increased...
