Device to-device communication
First Claim
1. An apparatus for use in a device-to-device, D2D, communication enabled user equipment, UE, comprising:
- a receiver to receive a signal from another UE;
a processor to determine, based on the received signal, a channel condition between the UE and the another UE, and to generate a dedicated information element (IE) that includes a plurality of integer values, the plurality of integer values to include a first integer value that corresponds to the channel condition, wherein the plurality is a number that is equal to or less than a predetermined limit of UEs with which the UE is to be connected in a D2D group; and
a transmitter to send the dedicated IE to report the determined channel condition to an evolved Node B, eNB, whereinthe processor is to initiate D2D communication based on a communication from the eNB, received in response to the report of the determined channel condition.

Abstract
An apparatus is provided for a device-to-device, D2D, communication enabled user equipment, UE, comprising a processing section to determine, based on a signal received from another UE, a channel condition between the UE and the another UE; the UE to report the determined channel condition to an evolved Node B, eNB. The processing section is to initiate D2D communication based on a communication from the eNB, received in response to the report. Also, an apparatus is provided for a network element, comprising An input to receive a describing a channel condition between a first UE and a second UE; a processor to determine, based on the channel condition, whether or not D2D communication between the first UE and the second UE is to be enabled; and an output to output a result of the determination when the processor determines D2D communication is to be enabled. Related methods are also provided.

23. A non-transient machine-readable storage medium having stored thereon instructions that, when executed by a computer, cause the computer to initiate device-to-device, D2D, communication between a plurality of user equipments UEs, the plurality of UEs forming a cluster, the instructions to cause the computer to:
-
determine, by a first UE, a channel condition, the channel condition associated with a signal received from a second UE, where the first UE and second UE are in the cluster; report the determined channel condition to an evolved Node B, eNB, using a dedicated information element (IE) that includes a plurality of integer values, the plurality of integer values to include a first integer value that corresponds to the channel condition, wherein the plurality is a number that is equal to or less than a predetermined limit of UEs with which the first UE is to be connected in a D2D group; and receive a result of a determination to enable D2D communication in response to the report of the determined channel condition.
