Abstract: Encoded control information can be mapped to an enhanced physical downlink control channel (ePDCCH) search space of a user equipment (UE) in accordance with an offset and aggregation level. The ePDCCH search space may include a physical resource block (PRB) set located in a data region of a downlink subframe. The encoded control information may be mapped into one or more enhanced control channel elements (eCCEs) of the ePDCCH search space beginning from a starting location. The starting location is an eCCE location within the PRB set. The PRB set, as well as the starting/eCCE location within the PRB set, are identified in accordance with an offset associated with the UE. A number of eCCEs carrying encoded information corresponds to an aggregation level.

Abstract: Methods and devices for reducing traffic over a wireless link through the compression or suppression of high layer packets carrying predictable background data prior to transportation over a wireless link. The methods include intercepting application layer protocol packets carrying the predictable background data. In embodiments where the background data is periodic in nature, the high layer packets may be compressed into low-layer signaling indicators for communication over a low-layer control channel (e.g., an on off keying (OOK) channel). Alternatively, the high layer packets may be suppressed entirely (not transported over the wireless link) when a receiver side daemon is configured to autonomously replicate the periodic background nature according to a projected interval. In other embodiments, compression techniques may be used to reduce overhead attributable to non-periodic background data that is predictable in context.

Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

Abstract: Embodiments are provided to implement a time/power/frequency hopping scheme for device-to-device (D2D) discovery. The embodiments improve the UE detection of D2D discovery signals from neighboring UEs and account for large number of UEs' discovery signals. This is achieved by having neighboring UEs transmitting at different time instances and at different power levels. Further, neighboring UEs can be configured to transmit on different frequencies. This is achieved by assigning different time/power/frequency sequences to different UEs. An embodiment method includes transmitting, to a UE, parameters a hopping pattern of a first sequence of resources for transmitting a discovery signal by the UE and of a second sequence of resources for receiving a second discovery signal by the UE. The first sequence of resources comprises at least one of a sequence of time instances and a sequence of power levels. The second sequence of resources comprises time instances.
