Abstract

In a method for controlling direct data transmission between a plurality of mobile devices in a wireless network, a master node or a plurality of the mobile devices in the network is selected for calculating an estimate of the average network load. The selected master node or the selected plurality of mobile devices calculates an estimate of the average network load. An optimal repetition factor,for direct communication between the mobile devices, is estimated based on the average network load. Resources are allocated based on the optimal repetition factor, and a message is transmitted from at least one of the mobile devices to at least another of the mobile devices using the allocated resources.

Description

technical field [0001] The present application relates to methods and apparatus for controlling direct data transfer between mobile devices in a wireless network. Background technique [0002] Traditional wireless networks for mobile devices (UEs) rely on cellular infrastructure to support UE communications. In these traditional networks, communication is controlled by network nodes even if communication occurs only between a pair of UEs. Among them, both uplink (UL) and downlink (DL) transmissions take place between the UE and the network node. [0003] Unlike inter-UE communication via network nodes, direct communication uses direct links between UEs. The only role (if any) of the network nodes in this process is to establish direct links and allocate resources. 3GPP LTE Release 13 allows for this type of decentralized communication, where the term "sidelink" is used to refer to a direct link between UEs. The PC5 interface at each UE facilitates the direct link between...
