Transmission resource configuration selection method, device and terminal

Abstract

The present invention provides a transmission resource configuration selection method, comprising: obtaining a resource configuration set, the resource configuration set includes at least one resource configuration; determining whether the value of the reservation counter of the resource configuration in the resource configuration set is 0, and if so, Start resource configuration selection or reselection; determine the resource configuration selection window, and remove unavailable resource configurations in the resource configuration set within the time range of the resource configuration selection window based on the sensing results in the sensing time window to obtain multiple candidate resource configurations; Randomly select a resource configuration among the plurality of candidate resource configurations, and send control signaling and data on resources included in the selected resource configuration, where the control signaling includes information about the resource configuration where the control signaling is sent and Reservation time information configured for the resource. The invention can simultaneously meet the requirements of the periodic data packets with the same size, the periodic data packets with different sizes and the non-periodic services for resource allocation.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and terminal for selecting transmission resource configuration. Background technique [0002] LTE (Long Term Evolution, long-term evolution) V2X (Vehicle-to-Everything, in-vehicle communication technology) has two resource acquisition methods: mode 3 is for the base station to allocate transmission resources, and mode 4 is for the terminal to obtain transmission resources through perception, which is a perception-based Semi-static resource allocation method (Sensing Based SPS), the specific working principle is described as follows: [0003] The Internet of Vehicles terminal confirms whether to perform resource selection or reselection according to whether the resource reselection counter is 0. The initial value of the resource reselection counter is configured or pre-configured by the Internet of Vehicles terminal at a high level after eac...

AI Technical Summary

Problems solved by technology

In LTE V2X transmission mode 4, the sender adopts perception-based semi-static resource allocation to obtain resources in the time domain and frequency domain. This mechanism has good performance for services with the same size of periodic data packets, but for Serious performance loss for different businesses and non-periodic businesses
