The invention provides a configuration method and device for secondary link semi-persistent scheduling. The method for configuring the secondary link semi-persistent scheduling includes: the UE receives a radio resource control connection reconfiguration message sent by the base station; the UE configures the secondary link semi-persistent scheduling according to the radio resource control connection reconfiguration message; wherein, the The radio resource control connection reconfiguration message includes a secondary link communication configuration information element, and the secondary link communication configuration information element includes a semi-persistent scheduling secondary link wireless network temporary identifier and semi-persistent scheduling configuration information. The method and device for configuring the secondary link semi-persistent scheduling provided by the present invention, for services with periodic characteristics, by adding the semi-persistent scheduling secondary link wireless network temporary identifier and semi-persistent scheduling configuration in the secondary link communication configuration information element information, so that the PC5 interface resources are allocated to the UE in a semi-persistent scheduling manner, which reduces the overhead of the air interface and reduces the overhead of PDCCH control signaling.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a configuration method and device for secondary link semi-persistent scheduling. 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 RAN#68 meeting, mainly researching the vehicle data transmission scheme based on the 3GPP communication protocol. V2X communication includes V2V (Vehicle-to-vehicle, vehicle-to-vehicle), V2I (Vehicle-to-infrastructure, vehicle-to-roadside infrastructure) communication and V2P (Vehicle-to-person) communication. V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-vehicle entertainment information, etc. [0003] The basic message types of V2X are divided into CAM (Cooperativ...
