Embodiment Construction

[0067] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0068] figure 1 A block diagram of a communication system provided by an exemplary embodiment of the present disclosure is shown. The communication system may be a schematic diagram of a non-roaming 5G system architecture (Non-roaming 5G system architecture), and the system architecture may be applied to a vehicle to everything (V2X) service using D2D technology.

[0069] The system architecture includes a data network (Data Network, DN), and a V2X application server (Application Server) required by the V2X service is set in the data network. The system architecture also includes a 5G core network. The network functions of the 5G core network include: Unified Data Management (UDM), Policy Control Function (PCF), Network Exposure Function (...

Abstract

The present disclosure provides a transmission power control method, device, device and storage medium for direct connection communication, and relates to the field of mobile communications. The method includes: a first UE sends the i th SL-RSRP report to a second UE; A UE restarts the high-layer filtering of SL-RSRP after sending the i-th SL-RSRP report for T duration; the first UE sends the i+1-th RSRP report to the second UE, the The i+1th SL-RSRP report is used for transmit power control by the second UE. The present disclosure enables the second UE to obtain a relatively accurate SL-RSRP report for each adjusted transmission power, improves the accuracy of the transmission power control of the transmitting end user equipment in the Internet of Vehicles communication, thereby reducing the number of interference between user equipment.

Description

technical field [0001] The present disclosure relates to the field of mobile communications, and in particular, to a transmission power control method, apparatus, device, and storage medium for direct-connect communication. Background technique [0002] Vehicle wireless communication technology (Vehicle to Everything, V2X) is a new generation of information communication technology that connects the vehicle with everything, where V represents the vehicle and X represents any object that interacts with the vehicle. Currently, X mainly includes vehicles, people, Traffic roadside infrastructure and networks. The information modes of V2X interaction include: vehicle-to-vehicle (Vehicle to Vehicle, V2V), vehicle-to-road (Vehicle to Infrastructure, V2I), vehicle-to-Pedestrian (V2P), vehicle-to-network (Vehicle to Pedestrian, V2P) Vehicle to Network, V2N) interaction. [0003] In the fifth-generation mobile communication technology (5th-Generation, 5G), for the unicast service an...
