Problems solved by technology

In the initial configuration of resources, terminal devices can use network configuration or pre-configuration to plan the initial resource pool. However, in this scenario, different resource pools may be configured between terminal devices, resulting in new air interface ( New Radio, NR) transmission and NR SL transmission use the same resources, resulting in coexistent co-channel interference, resulting in a reduction in transmission quality

Embodiment Construction

[0040] For ease of understanding, terms involved in this application are first introduced.

[0041]1. Vehicle-to-everything (V2X) communication

[0042] V2X communication refers to the communication between vehicles and anything in the outside world. V2X communication can include but is not limited to: vehicle-to-vehicle (V2V) communication, vehicle-to-pedestrian (V2P) communication, vehicle-infrastructure (vehicle-to-pedestrian, V2P) communication to infrastructure, V2I) communication, vehicle to network (V2N) communication.

[0043] 2. Sidelink (SL)

[0044] SL is a new link type introduced to support direct communication between V2X devices. NR SL is mainly composed of Physical Sidelink Control Channel (PSCCH), Physical Sidelink Shared Channel (PSSCH) and Physical Sidelink Broadcast Channel (PSBCH). It is composed of a sidelink physical feedback channel (Physical SidelinkFeedback Channel, PSFCH).

Abstract

The embodiment of the invention discloses a sidelink interference elimination method and a sidelink interference elimination device, which can be applied to systems such as Internet of Vehicles, V2X, V2V and the like, and the method comprises the following steps: determining a resource occupation condition of first terminal equipment; and sending the resource occupation condition of the first terminal device. By implementing the embodiment of the invention, the terminals can know the corresponding resource occupation condition mutually, so that the same-frequency interference is avoided, the purpose of eliminating the interference is achieved, and the transmission quality is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and apparatus for eliminating sidelink interference. Background technique [0002] In the Internet of Vehicles, the terminal device communicates with the terminal device through a sidelink (SL), and the resources for SL transmission are allocated according to the corresponding resource pool. In the initial configuration of resources, the terminal device can use network configuration or pre-configuration to plan the initial resource pool. However, in this scenario, different resource pools may be configured between terminal devices, resulting in the new air interface ( New Radio, NR) transmission and NR SL transmission use the same resources, resulting in co-existing co-channel interference, resulting in reduced transmission quality. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a method and device for eliminat...
