Abstract

The present application discloses a method for transmitting a sounding reference signal, a terminal device, and a network device. The method includes: the terminal device determines, in a first time-domain resource unit, a plurality of first sounding reference signal SRS for sending the terminal device. Two time-domain resource units; the terminal device determines target resources for sending the SRS on the plurality of second time-domain resource units according to the frequency hopping pattern of the terminal device; The target resource sends the SRS to the network device. Therefore, the interference of SRS signals between different terminal equipments is reduced, and the situation of continuous strong interference between terminal equipments is also avoided.

Description

technical field [0001] The embodiments of the present application relate to the field of wireless communication, and more specifically, relate to a method for transmitting a sounding reference signal, a terminal device, and a network device. Background technique [0002] In the Long Term Evolution ("LTE") system, the terminal will receive the cell sounding reference signal (Sounding Reference Signal, "SRS") subframe broadcast by the network side through high-level signaling, and the SRS can only be used in the cell SRS transmitted in subframes. The terminal needs to perform rate matching on the Physical Uplink Shared Channel (Physical Uplink Shared Channel, “PUSCH”) or the Physical Uplink Control Channel (Physical Uplink Control Channel, “PUCCH”) in the SRS subframe of the cell when performing data transmission. If in the SRS subframe of the cell, the terminal conflicts between the bandwidth for transmitting PUCCH or PUSCH and the bandwidth for transmitting SRS resources, t...
