Abstract: Disclosed is a sounding reference signal (SRS) transmission method. The method comprises: determining a resource on an unlicensed carrier for transmitting an SRS; and transmitting the SRS according to the determined resource. The invention solves a problem in the prior art in which transmitting an SRS on an unlicensed carrier is less feasible, thereby increasing feasibility of transmitting an SRS on an unlicensed carrier. Also disclosed are an SRS reception method, an apparatus, a system, and a storage medium.

Abstract: A configuration method for resource sharing among multiple wireless links is provided. The multiple wireless links include a first link and a second link, or include a first link, a second link and a third link. In the method, P-Q configuration is performed on a set N formed by a group of continuous units, and a set P configured for downlink transmission of the second link/third link and a set Q configured for uplink transmission of the second link/third link in the set N are determined; U-V configuration is performed on the set N, and a set U configured for downlink transmission of the first link/third link and a set V configured for uplink transmission of the first link/third link in the set N are determined; and a set S for uplink transmission of the second link/third link and downlink transmission of the second link/third link is determined.

Abstract: Provided are a preamble transmission method and apparatus. The method comprises: a UE executing LBT on a first time frequency resource of an unlicensed carrier until a right to use the unlicensed carrier is acquired, wherein the LBT comprises LBT executed for transmitting a preamble; and after a right to use the access to the unlicensed carrier is acquired, the UE transmitting the preamble on a second time frequency resource located behind the first time frequency resource, wherein the second time frequency resource is a pre-configured PRACH time frequency resource at a fixed position, or a PRACH time frequency resource determined according to an LBT execution position. By means of the present disclosure, the problem in the relevant art of intra-cell interference caused by uplink data transmission over an unlicensed carrier is solved, and the uplink data transmission quality is improved.

Abstract: The present disclosure provides a method and an apparatus for determining a Listen Before Talk (LBT) mode, as well as a method for LBT mode switching. The method includes: determining (100) an LBT mechanism and/or an LBT mechanism parameter set based on related indication information and/or priority information and/or measurement information; and performing (101), by a transmitting device, contention-based channel access based on the determined LBT mechanism and/or LBT mechanism parameter set. With the present disclosure, an LBT mode can be determined. With the selection of the LBT mode, it is possible to avoid waste of channel resources and indication information due to an improper LBT mode, thereby improving an efficiency of contention-based channel access.
