Abstract
describes the discovery signal generation and D2D discovery signal transmission and scheduling of physical layer processing and process the device (D2D) with respect to the device. The invention claims a method for detecting and measuring the D2D signal D2D signal identification management and by a wireless transmit/receive unit (WTRU) for scheduling monitoring PDCCH. The D2D discovery may be configured the WTRU D2D specific transmitting/receiving timing mode. the discovery signal may carry transmitting a discovery signal for explicit information regarding the user and/or service identification payload and may be mapped to physical resources to the decoupling/receiving from the downlink operation. The WTRU may D2D finds that signal quality is measured and reported to the network.
Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal D2D signal identity management and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.
