摘要:
An apparatus and method of allowing user equipment (UE) to transmit information directly with other user equipment, using a device-to-device (D2D) mode is disclosed herein. A D2D UE (dUE1) that wishes so communicate to another UE (dUE2) in D2D mode makes various communications requests to an Evolved Node B (eNB), which can facilitate the connection between dUE1 and dUE2 by having the dUE1 measure the signals from dUE2 to help establish a D2D connection between the dUE1 and the dUE2.
摘要:
A signal structure for use in D2D communications is described. In one embodiment, a preamble for automatic gain control at the receiver end is included in the transmitted signal. Techniques for scheduling of D2D transmissions using carrier sensing multiple access (CSMA) and a power control schemes for interference management are also described.
摘要:
An apparatus and method that allow user equipment (UE) to transmit information directly with other user equipment, using a device-to-device (D2D) mode is disclosed herein. A first D2D UE (dUE1) that wishes so communicate to a second D2D UE (dUE2) in D2D mode makes various communications requests to an Evolved Node B (eNB), which can facilitate the connection between the dUE1 and the dUE2. Among these requests are to make the D2D connection via WiFi instead of via Long Term Evolution (LTE). The eNB determines the WiFi capabilities of dUE1 and dUE2, then assigns a subset of available channels to be scanned by dUE1 and a separate subset of available channels to be scanned by dUE2. Thereafter, the eNB can assign a WiFi channel based on the scans performed by dUE1 and dUE2.

An apparatus may include a transceiver operable to receive a downlink message from a base station for a serving cell, the downlink message allocating a set of control parameters. The apparatus may also include a processor circuit communicatively coupled to the transceiver and an uplink power control module operable on the processor circuit to read the set of control parameters, and apply a signal-to-noise-and-interference (SINR) parameter based on the received set of control parameters to determine physical uplink shared channel (PUSCH) power to be applied for a PUSCH transmission. Other embodiments are disclosed and claimed.

摘要:
Embodiments of user equipment and methods for improved uplink transmission power management and scheduling, are generally described herein. For example, in an aspect, a method of uplink power management is presented, the method includes determining whether a total desired transmission power exceeds a total configured maximum output power for a subframe. When the total desired transmission power exceeds the total configured maximum output power, the method includes allocating a minimum proactive power limitation to each serving cell, assigning a remaining power to one or more channels based on priority, and computing a total power assignment based on the allocating and the assigning.

Machine-readable media, methods, apparatus and system for transmitting ACK/NACK signal in a wireless communication system are described. In some embodiments, a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information may be determined. Then, the sequence may be mapped onto a transmission channel for later transmission from the mobile station to a base station. In some embodiments, the transmission channel may be allocated with at least a part of three feedback mini-tiles (FMTs), wherein each of the FMTs comprises two subcarriers contiguous in frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in time domain and the three FMTs being discontinuous in frequency domain.
