D2D (device to device) resource allocation method, D2D data transmission method and device

Abstract

Disclosed are a D2D resource allocation method, and data transmission method and device, the D2D resource allocation method comprising: determining a D2D resource configuration corresponding to the quality of service (QoS) level of a D2D service; and transmitting to a user equipment (UE) the information of the D2D resource configuration corresponding to the service quality level of the D2D service. The D2D data transmission method comprises: according to the received information of the D2D resource configuration corresponding to the service quality level of the D2D service, selecting a transmission resource for the D2D service to be transmitted; and transmitting the data of the D2D service over the selected transmission resource. The D2D service transmission requirement is considered in allocating and selecting D2D resources, thus further improving the system D2D resource allocation efficiency without affecting the D2D service transmission requirement.

AI Technical Summary

Benefits of technology

This patented technology describes methods for efficiently assigning radio frequency spectrum bands or other wireless communication devices' resources among different users within an area served through one network node while ensuring that they receive sufficient signal strength from each user terminal at all times during their assigned time period. By doing this, these systems improve spectral utilization rates and reduce interference caused by neighbor cells. Additionally, it suggests sending specific types of signals called pilot sequences along certain directions over designated frequencies instead of transmitting them continuously throughout its entire bandwidth. These techniques help ensure efficient use of available licensed spectra space and enhance overall performance of mobile networks. Overall, this approach helps optimize usage of both cellular and non-cellular technologies like LTE/UMTS and WiFi.

Problems solved by technology

This patented describes various technical problem addressed in current systems such as Layer-3 Cell Broadcast Service (LLCSA2) and General Packet Radio System (GSM)/Enhanced Data Overall, these techniques aim at improving wireless communications networks while optimizing their use of radio access technology (RAT)-Direct Digital Subscriber Line Access Multiplexing Protocol (DSLDP) protocol for efficient data transfer among multiple users connected over shared channels without interference from signals transmitted simultaneously across those interfaces.
