Abstract

The invention discloses a method and an apparatus in a node used for wireless communication. The first node receives the first signaling in the first time window; sending a second signaling and a second signal on a second time-frequency resource block; the first signaling comprises a first priority and a first identifier; the second signaling comprises a second priority and a second identifier; the first priority and the second priority are jointly used for determining a first threshold value and a second threshold value; whether the first identifier and the second identifier are the same or not is used for determining whether a target threshold value is the first threshold value or the second threshold value; the first time-frequency resource block is associated to a first target time-frequency resource block, and the target threshold value is used for determining whether the first target time-frequency resource block belongs to a first alternative resource pool or not. The problem of hidden nodes of the same receiving user is effectively solved under the condition that no signaling overhead is increased.

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...
