As shown in fig. 1, one embodiment of the present invention provides an SRS transmission method 100, which may be performed by a terminal device, including the steps of:

s102: if the additional SRS and the PUSCH transmission resources collide, the PUSCH is preferentially transmitted, and part or all of the additional SRS is discarded.

The above transmission resources include at least one of transmission time domain resources and transmission frequency domain resources, and the step of collision between the additional SRS and PUSCH transmission resources may specifically include the following three cases: additional SRS and PUSCH transmission time domain resource collisions; or the additional SRS and the PUSCH transmit frequency domain resource conflict; or the additional SRS and PUSCH transmit time domain resources and transmit frequency domain resources collide.

The additional SRS and PUSCH transmission resources mentioned in this step collide, specifically, all of the additional SRS collide with PUSCH transmission resources; or that part of the additional SRS collides with PUSCH transmission resources.

If the additional SRS and PUSCH transmission resources mentioned in this step collide, part or all of the additional SRS is specifically, for example:

all of the additional SRS collides with the PUSCH transmission resource, and all of the additional SRS is discarded;

for another example, if the portion of the additional SRS collides with the PUSCH transmission resource, only the portion of the additional SRS that collides with the PUSCH transmission resource may be discarded, and the PUSCH and the portion of the additional SRS that does not collide with the PUSCH transmission resource may be preferentially transmitted.

As another example, if a portion of the additional SRS collides with PUSCH transmission resources, then all of the additional SRS may be discarded.

According to the SRS transmission method provided by the embodiment of the invention, when the transmission resources of the additional SRS and the PUSCH conflict, the PUSCH is preferentially transmitted, and part or all of the additional SRS is discarded. The embodiment of the invention provides a conflict processing mechanism for the additional SRS and the PUSCH, is convenient for improving the receiving correctness of the PUSCH and the additional SRS and improving the communication effectiveness.

Optionally, after discarding part or all of the additional SRS in S102 of the foregoing embodiment, the method may further include the following steps: transmitting part or all of the additional SRS over a target resource; wherein the target resource comprises: the additional SRS transmission resources that are closest to and available to the transmission resources where the additional SRS collide.

s202: if the additional SRS and the PUSCH transmission resources collide, the PUSCH is preferentially transmitted, and part or all of the additional SRS is discarded.

The execution of this step can be seen in S102 of the above embodiment.

S204: part or all of the additional SRS is transmitted through the target resource.

Wherein, the target resource and the transmission resource of the PUSCH do not collide.

The additional SRS transmitted through the target resource in S204 may be part or all of the above-described discarding in S202. Specifically, for example, the portion of the additional SRS transmission resource collision is discarded in S202, and the portion of the additional SRS transmission resource collision is transmitted through the target resource in S204; for another example, all of the additional SRS is discarded in S202, and all of the additional SRS is transmitted through the target resource in S204.

Optionally, in S202, the additional SRS and PUSCH transmit resource conflicts in one TTI, and the target resources include: additional SRS transmission resources available in a next TTI of the above TTI. The next TTI of the above TTI may specifically be the first TTI after the above TTI, or may also be the second TTI, the third TTI, or the like after the above TTI.

Optionally, the target resource includes: the next available additional SRS transmission resource. Wherein the available additional SRS transmission resources are semi-statically configured by the network device.

Optionally, the target resource may be indicated by the network device, so before part or all of the additional SRS is transmitted through the target resource in S204, the method further includes the following steps: receiving indication information; and determining the target resource according to the indication information.

In this embodiment, the network device may indicate a time-frequency resource for the additional SRS with the transmission resource conflict, and timely send the additional SRS with the transmission resource conflict, so as to improve the transmission effectiveness of the additional SRS.

Alternatively, the target resource may be semi-statically configured, so that the terminal device may further determine the target resource before the S204 transmits part or all of the additional SRS through the target resource.

In this embodiment, the terminal may timely send the additional SRS with the transmission resource conflict through the target resource configured in a semi-static manner, so as to improve the transmission effectiveness of the additional SRS.

According to the SRS transmission method provided by the embodiment of the invention, when the transmission resources of the additional SRS and the PUSCH conflict, the PUSCH is preferentially transmitted, part or all of the additional SRS is discarded, and the additional SRS is transmitted through the target time-frequency resource. The embodiment of the invention provides a conflict processing mechanism for the additional SRS and the PUSCH, is convenient for improving the receiving correctness of the PUSCH and the additional SRS and improving the communication effectiveness.
