摘要:
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:
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:
Technology is discussed for supporting wireless communication paths from an antenna array with a vertical directional component. Examples reduce training feedback for increased numbers of communication paths by only reporting on a subset of Reference Signals (RSs) provided for various vertical beam configurations. Additional examples reduce feedback with virtual measurements based on a difference between RS measurements. One such measurement can come from full set of RSs for a reference beam configuration and another from a partial set of RSs for an additional beam configuration. Such virtual measurements can also be based on cross correlation for beamforming weights associated with the two configurations. Several examples of preparing and sending measurement reports consistent with Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards are discussed. The supporting technology also increases diversity and reduces a power differential between spatially multiplexed layers transmitting a common codeword.

An apparatus includes a processor a channel state information (CSI) module operative on the processor to evaluate channel state information for a multiplicity of transmission points and to allocate a selection of channel state information reference signals (CSI-RS) to an uplink sub-frame allotted for transmitting channel quality/precoding matrix index/rank indicator (CQI/PMI/RI) information to a transmission point. The apparatus may further include a wireless transceiver operative to transmit the selection of CSI-RS in the uplink sub-frame to the transmission point in a wireless network, and receive information from the transmission point in response to the CSI-RS and a digital display operative to present the information received from the transmission point.

摘要:
Apparatuses and methods for channel state information reference signal (CSI-RS) configuration in distributed remote radio head (RRH) systems are described. A transmission point selection module can receive a user equipment (UE) signal via a transmission point from a plurality of transmission points sharing a single cell identification. A downlink transmission point can be selected based on the UE signal. The UE can then be configured to report CSI-RS measurements for the selected downlink transmission point.

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.
