Abstract

Embodiments of the present disclosure relate to a method, device and computer readable media for communications. A method comprises receiving, at a first terminal device from a second terminal device, information about a first set of candidate resources for the first terminal device to perform a sidelink transmission. The method further comprises determining a second set of candidate resources for performing the sidelink transmission. The method further comprises determining a first subset of the second set by identifying an overlap between the first set and the second set based at least on the information. The method further comprises selecting target resources for the sidelink transmission based at least on the first subset.

Description

TECHNICAL FIELD Embodiments of the present disclosure generally relate to the field of telecommunication, and in particular, to a method, device and computer readable medium for communications. BACKGROUND Certain communication systems enable vehicle to everything (V2X) and device to device (D2D) communications to be performed. V2X communications can be based on communication technologies such as sidelink communication technologies. For this, sidelink resource pools and sidelink channels can be established for vehicles participating in such communications. In V2X communications, there are two modes of resource allocation. In a first mode (also referred to as NR V2X mode 1 or mode 1 hereinafter), one terminal device may perform V2X communications with the other terminal device by using resources allocated by a network device. In a second mode (also referred to as NR V2X mode 2 or mode 2 hereinafter), one terminal device may perform V2X communications with the other terminal device by using resources autonomously selected in a resource pool by the one terminal device. In order to enhance reliability and reduce latency, feasibility and benefit of the enhancements in the mode 2 need to be studied. SUMMARY In general, example embodiments of the present disclosure provide a method, device and computer readable medium for communications. In a first aspect, there is provided a method for communications. The method comprises receiving, at a first terminal device from a second terminal device, information about a first set of candidate resources for the first terminal device to perform a sidelink transmission. The method further comprises determining a second set of candidate resources for performing the sidelink transmission. The method further comprises determining a first subset of the second set by identifying an overlap between the first set and the second set based at least on the information. The method further comprises selecting target resources for the sidelink transmission based at least on the first subset. In a second aspect, there is provided a terminal device. The terminal device comprises a processor and a memory storing instructions. The memory and the instructions are configured, with the processor, to cause the terminal device to perform the method according to the first aspect. In a third aspect, there is provided a computer readable medium having instructions stored thereon. The instructions, when executed on at least one processor of a device, cause the device to perform the method according to the first aspect. It is to be understood that the summary section is not intended to identify key or essential features of embodiments of the present disclosure, nor is it intended to be used to limit the scope of the present disclosure. Other features of the present disclosure will become easily comprehensible through the following description.
