Abstract

The invention discloses a method and an apparatus in a node used for wireless communication. The first node receives the first signaling and executes first channel sensing in the first resource pool; and sending a second signaling on the target time-frequency resource block, the first signaling is used for indicating a first time-frequency resource set; the second signaling comprises a first priority, and the first priority is used for determining a first threshold value and a second threshold value; the first threshold value is higher than the second threshold value; whether the first time-frequency resource block belongs to the first time-frequency resource set or not is used for determining whether a first target threshold value is one of the first threshold value or the second threshold value; the first time-frequency resource block is associated to a second time-frequency resource block; the first target threshold value is used for determining whether the second time-frequency resource block belongs to a first alternative resource pool or not when the first node executes the first channel perception. According to the method, coordinated resources among users are effectively utilized, and the freedom degree of resource selection is guaranteed.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a sidelink-related transmission scheme and device in wireless communication. Background technique [0002] Starting from LTE (Long Term Evolution, long-term evolution), 3GPP (3rd Generation Partner Project, third-generation partnership project) has been developing SL (Sidelink, secondary link) as a direct communication method between users, and in In Rel-16 (Release-16, version 16), the first NR SL (New Radio Sidelink, new air interface secondary link) standard of "5G V2X with NR Sidelink" was completed. In Rel-16, NR SL is mainly designed for V2X (Vehicle-To-Everything, Internet of Vehicles), but it can also be used for Public Safety. [0003] However, due to time constraints, NR SL Rel-16 cannot fully support the business requirements and working scenarios identified by 3GPP for 5G V2X. So 3GPP will enhance NR SL in Rel-17. Con...
