Abstract:
Device-to-device (D2D) communications between user equipment (UE) allows two UEs in a long-term evolution (LTE) network to communicate directly with each other without the need to first send their communications to a network (such as via an evolved node B). In order to communicate in a D2D mode, the UEs first need to discover each other. One method of allowing the UEs to discover each other involves the use of a physical uplink control channel (PUCCH). After a network determines that certain UEs would benefit from D2D communication, the UEs can be set up to send and receive discovery signals using the PUCCH.
