Problems solved by technology

The base station coverage and capacity of telecom operators are planned according to the density distribution of traditional types of terminals (such as mobile phones), and it is difficult to guarantee good coverage for D2D / OBU terminals
What's more serious is that if telecom operators are unwilling to upgrade base stations and optimize networks to support D2D / V2V services in consideration of cost, D2D / OBU terminals may be completely in the Out of coverage scenario. At this time, LTE D2D and LTE V2V technologies are also Only random selection of resource pools or LBT methods can be used, and its performance is hardly better than pure Ad Hoc systems such as IEEE 802.11p

Abstract

An embodiment of the present invention proposes a method for secondary link data transmission, including: the scheduling terminal sends the first physical control signaling to the sending terminal, and the first physical control signaling includes a method for transmitting the first type of system information The scheduling terminal sends the first type of system information to the sending terminal, where the first type of system information includes secondary link resource pool information, and the secondary link resource pool information is used for the transmission The terminal performs secondary link transmission with the receiving terminal. In the embodiment of the present invention, the scheduling terminal can configure Sidelink transmission resources for the sending terminal, which can significantly improve the success rate of D2D and V2V communication, reduce time delay, and expand the capacity of D2D and V2V communication.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a method and terminal for secondary link data transmission. Background technique [0002] Device to Device (Device to Device, D2D) communication and Vehicle to X (Vehicle to X, V2X) Internet of Vehicles communication has become a hot area of ​​wireless communication technology development, where V2X includes Vehicle to Vehicle (Vehicle to Vehicle, V2V) communication, vehicle -Road facility (Vehicle to Infrastructure, V2I) communication and vehicle-pedestrian (Vehicle to Pedestrian, V2P) communication, etc. [0003] D2D communication can be used for new services such as social networking, shopping and entertainment, and rescue and disaster relief. V2V communication can share sensing information such as on-board radar and camera between vehicles through wireless communication between multiple on-board units (On board Unit, OBU). The line-of-sight ra...
