Abstract

This invention relates to a method and apparatus of the resource selection for sidelink communication. The method comprises segmenting a packet with a packet size larger than a predetermined value into a base part and an aperiodic part; transmitting the base part through periodic traffic and sending a resource request of the aperiodic part to a group leader; and transmitting the aperiodic part through the group leader based on the resources allocated by a joint resource selection. The method also comprises receiving a resource request of an aperiodic part sent by a group member; and allocating the resources to the group member based on a joint resource selection. The method and apparatus ensure the persistence of V2X periodic traffic and improve the efficiency of resource allocation.

Description

technical field

[0001] The present invention relates to a method and apparatus for a resource selection scheme for sidelink communications. Background technique

[0002] With the cross-generational development of communication technology, vehicle networking can realize the comprehensive network architecture of V2X (vehicle-connected everything) within the vehicle, vehicle-to-vehicle, vehicle-to-road, vehicle-to-person, and vehicle-to-cloud service platforms, thereby greatly improving vehicle intelligence. . LTE-V2X mainly solves the problem of "sensor sharing" between traffic entities. It can extend the range of on-board detection systems (such as radar and cameras) from the line-of-sight range of tens of meters to the non-line-of-sight range of hundreds of meters, and double the efficiency of on-board AI to achieve assistance in relatively simple traffic scenarios. drive.

[0003] LTE V2X includes two technologies: LTE-V-Cell and LTE-V-Direct. LTE-V-Cell is based on bas...
