Abstract: Embodiments of the present disclosure relate to devices, methods, devices and computer readable storage media for resource selection in a Vehicle to Everything (V2X) communication. The method comprises determining, at a terminal device, a resource reservation period for at least one sidelink transmission; and in accordance with a determination, based on the resource reservation period, that a reference resource associated with the at least one sidelink transmission is subsequent to a sensing window, determining, from a resource selection window of the terminal device, at least one further reference resource to be reserved for the at least one sidelink transmission based on the resource reservation period. In this way, the conflict of resource selection can be avoided and therefore the performance of the sidelink transmission can be improved.

Abstract: Embodiments of the present disclosure provide a solution for sensing sidelink resources. In a method for communication, in accordance with receiving, at a terminal device from a network device, a first higher layer parameter indicating that partial sensing is enabled for the terminal device, the terminal device determines a candidate resource for performing a sidelink transmission in a target slot. The terminal device determines, for the partial sensing, a sensing window with a configured time length before the target slot. The terminal device determines, in the sensing window, a set of slots based on the configured time length of the sensing window. The terminal device determines a reservation state of the candidate resource by monitoring the set of slots. With the embodiments of the present disclosure, a feasible partial sensing procedure is provided for a terminal device to perform a sidelink transmission in the 5G NR, and thus the performance of sidelink transmissions can be improved.
