摘要:
This application discusses, among other things, methods and apparatus for providing more efficient ways to enable D2D discovery and D2D communication simultaneously. In an example, a method can include assembling device-to device (D2D) discovery data at a wireless device, assembling D2D communication data at the wireless device, assembling a D2D preamble including the discovery data and the communication data, and transmitting the D2D preamble using a wireless transmitter of the wireless device.

A device includes a transceiver to receive, from a base station, a physical downlink shared channel (PDSCH) transmission and processing circuitry to classify downlink (DL) subframe types for a set of DL subframes associated with a first uplink (UL) subframe for transmission of a hybrid automatic report request acknowledgment (HARQ-ACK) and perform physical uplink control channel (PUCCH) resources mapping based on the classified DL subframe Types for an acknowledgement transmission associated with PDSCH transmission reception.
摘要:
An apparatus, system, and method for space-time cochannel interference cancellation are described. The apparatus may include a time stacking module to stack consecutive subcarrier signals for a period of time equal to several symbols and a space-time subcarrier beamformer module to perform space-time subcarrier beamforming by applying space-time beamformer weights to stacked symbols on one or more subcarriers. The space-time beamformer weights may be calculated based on spatial and time correlation properties of one or more interference signals. Other embodiments are described and claimed.

Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Apparatuses and methods for supporting operation of narrow bandwidth devices within a broadband network are described herein. A user equipment (UE) may retrieve control channels within a narrow bandwidth device region of a downlink subframe. The control channels may be received in a subcarrier of a new carrier type (NCT) implemented in accordance with a standard of the 3GPP family of standards. Cell-specific reference signals may be excluded on the NCT subcarrier.

摘要:
A system for communicating through a multicarrier communication channel estimates a channel transfer function Hnm(K) each of a plurality of subcarriers of a multicarrier communication channel from received training signals. The system also estimates a spatial correlation matrix Rnn(k) for each subcarrier from noise and interference samples obtained during the reception of the training signals through two or more receive-signal paths. Receiver and transmitter beamformer weights may be generated for the subcarriers using the channel transfer function Hnm(k) and the spatial correlation matrices Rnn(k) for use in subsequent communication through the channel.
摘要:
In a multicarrier receiver, spatial correlation estimates are enhanced by multiplying by weighting values generated from a channel length estimate. The channel length estimate is calculated from a channel estimate (e.g., an estimate of the channel response function) and a signal-to-noise ratio estimate. The spatial correlation estimates represent the correlation between frequency-domain samples from different antennas.
