Embodiment Construction

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0018] The biggest difference between the Sidelink SPS mechanism and the LTE R9SPS mechanism is that the multi-period SPS mechanism is introduced, and the reporting of UE assistance information is added, so that the base station eNB can better configure SL SPS and activate and release SL SPS resources. The embodiment of the present invention propo...

Abstract

The embodiment of the invention provides a semi-persistent scheduling resource allocation method and a base station. The method comprises the steps that if it is judged that the SL SPS resource release requirement exists or the SL SPS service release request sent by UE is received, and remaining control resources exist, the UE is authorized to be indicated to release the SL SPS resource; If it isjudged that the SL SPS service meeting the redistribution condition exists and the remaining control resources and service resources exist, the SL SPS resource is redistributed to the corresponding UE; And if it is judged that the SL SPS new access service exists and the remaining control resources and service resources exist, SPS resources are allocated to the corresponding UE. According to the semi-persistent scheduling resource allocation method and the base station provided by the embodiment of the invention, the classification and priority processing process of the SL SPS service is given, the resources can be more effectively utilized and allocated on the premise of ensuring the QoS of the user, and the resource utilization rate and the system capacity are improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of wireless communication, and specifically relates to a semi-persistent scheduling resource allocation method and a base station. Background technique [0002] V2X (Vehicle to X), that is, the information exchange between the vehicle and the outside world, is the key technology of the future intelligent transportation system. V2X was approved as a project at the 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) RAN#68 meeting, mainly researching the vehicle data transmission scheme based on the 3GPP communication protocol. V2X communication includes V2V communication (vehicle-to-vehicle communication), V2I communication (vehicle-to-roadside infrastructure communication) and V2P communication (vehicle-to-pedestrian communication). V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-v...
