Abstract

Methods and apparatuses for device-to-device (D2D) communication are provided. In an method, configuration messages including configuration information with respect to a control channel for the D2D communication is generated (S201) and the configuration messages are transmitted (S202) to user equipments that support D2D communication. With the methods and apparatuses, resources used for D2D control channel are reasonably allocated to explore diversity gain or reduce interference.

Description

technical field [0001] The non-limiting and exemplary embodiments of the present disclosure herein relate to the field of wireless communications. In particular, embodiments herein relate to methods and apparatus for device-to-device (D2D) communication. Background technique [0002] Recent developments in 3GPP Long Term Evolution (LTE) facilitate access to local IP-based services in homes, offices, public hotspots, or even outdoor environments. One of the important use cases of local IP access and local connection involves direct communication between devices that are close to each other (usually less than tens of meters, but sometimes up to hundreds of meters), an exemplary scenario is in figure 1 shown in . Such as figure 1 As illustrated in , in addition to communicating with the BS, two D2D-enabled user equipments (UEs) 1 and 2 also communicate directly with each other. Since D2D-enabled UEs are much closer to each other than cellular devices that must communicate v...
