Switching between sidelink transmission and reception

Abstract

A first wireless device receives first sidelink control information (SCI): scheduling a reception of a first PSSCH, and indicating that the first wireless device transmits a first physical sidelink feedback channel (PSFCH) via a first PSFCH resource. The first wireless device transmits a second SCI: scheduling a transmission of a second PSSCH, and indicating that the first wireless device receives a second PSFCH via the first PSFCH resource. Based on a result of a listen-before-talk (LBT) procedure on a PSFCH transmission associated with the first PSSCH, the first wireless device does not transmit, via the first PSFCH resource, the first PSFCH associated with a first priority value. The first wireless device receives, via the first PSFCH resource, the second PSFCH associated with a second priority value, wherein the second priority value is higher than the first priority value.
