Methods and apparatuses for device-to-device communication
First Claim
1. A user equipment (UE) for a cellular communication network configured to communicate in a duplex mode with a network node of the cellular communication network, transmitting data to the network node in an up-link (UL) duplex resource, and receiving data from the network node in a down-link (DL) duplex resource;
- whereinthe UE is further capable of direct device-to-device (D2D) communication with an other UE of the cellular communication network using the UL duplex resource; and
the UE comprises a transceiver configured to, as part of a D2D control procedure;
receive, from the network node, a grant to listen to a transmission in the UL duplex resource from the other UE to the network node;
in response to receiving said grant, listen to said transmission in the UL duplex resource from the other UE; and
determine a quality metric of said transmission from the other UE as received by the transceiver of the UE.

Abstract
A UE for a cellular communication network is disclosed. The UE is adapted to communicate in a duplex mode with a network node of the cellular communication network, transmitting data to the network node in a UL duplex resource, and receiving data from the network node in a DL duplex resource. The UE is further capable of direct D2D communication with another UE of the cellular communication network using the UL duplex resource. The UE comprises a transceiver adapted to, as part of a D2D control procedure, receive, from the network node, a grant to listen to a transmission in the UL duplex resource from the other UE to the network node. Furthermore, the transceiver is adapted to, as part of the D2D control procedure, in response to receiving said grant, listen to said transmission in the UL duplex resource from the other UE, and determine a quality metric of said transmission from the other UE as received by the transceiver of the UE. A corresponding network node and corresponding methods are also disclosed.
