PACKET DATA UNIT MAPPING INTO TIME RESOURCE PATTERNS FOR EFFICIENT DEVICE-TO-DEVICE COMMUNICATIONS

摘要

A User Equipment (UE) device or network system facilitates direct device-to-device (D2D) communication with another UE device, in which a single scheduling assignment indicates the transmission of packet data units, their corresponding retransmissions, and a mapping scheme into an available resource pool. The UE device operates to switch between a D2D communication and a cellular network communication. A single SA transmission from the UE enables the D2D communication by providing mapping parameters for decoding a subsequent SA transmission and a detection of the PDUs within sub-frames between two SA transmissions.
