Abstract: Wireless communication devices are adapted to facilitate transmission and reception of non-orthogonal communications. In one example, wireless communication devices can encode an amount of data in accordance with information that at least some of the data will be transmitted as part of a non-orthogonal transmission. The wireless communication device may further transmit the encoded data, and the encoded data can be non-orthogonally combined as part of a non-orthogonal transmission. In another example, wireless communication devices can receive a wireless transmission including a plurality of data streams non-orthogonally combined together. The wireless communication device may decode at least one of the data streams. Other aspects, embodiments, and features are also included.

Abstract: Apparatuses and methods for performing asynchronous multicarrier communications are provided. One such method involves generating, at a first wireless device, a waveform including one or more carriers, shaping the waveform to reduce interference between the waveform and adjacent waveforms, and transmitting, on a spectrum, the shaped waveform asynchronously.

Abstract: Embodiments herein maximize frame usage by selectively arranging the data within the frame thereby giving the transmitting processor additional time generate and transmit the data within the frame without increasing the time gap G of the frame and without increasing the overall length of the frame. Further, the selective arrangement also gives the receiving processor additional time to process the data of the frame and send Ack/Nack information regarding the success/failure of the processing without increasing the time gap G of the frame and without increasing the overall length of the frame. Other aspects, embodiments, and features are also claimed and described.

Abstract: An idle mode UE can RACH to a cell different from the cell paging the UE. The UE can be allocated additional time to respond to all cells in the neighborhood to identify the cell in which to RACH. Interference cancellation can occur at different rates based on whether the UE is in connected mode or idle mode. The time to respond to the page can be a function of a paging cycle. Additionally, a variable bias may promote early handoff to lower power cells and late handoff to high power cells.

Abstract: Techniques are described for wireless communication. A first method includes measuring, by a first device, a condition of a wireless channel; and generating at least one channel side information feedback message based on the measured condition of the wireless channel. The at least one channel side information feedback message provides information on a relationship of a set of parameters, including a data rate parameter, an error probability parameter, and at least one of a deadline parameter or a transmission link parameter. A second method includes measuring, by a first device, interference on a wireless channel; identifying an interfering device for the wireless channel based on the measurement; and generating a channel side information feedback message based on the measured interference on the wireless channel. The channel side information feedback message indicates the interfering device for the wireless channel and a correlation of interference from the interfering device with time or frequency.

Abstract: Apparatuses and methodologies are described that enhance performance in a wireless communication system using beamforming transmissions. According to one aspect, the channel quality is monitored. Channel quality indicators can be used to select a scheduling technique, such as space division multiplexing (SDM), multiple-input multiple output (MIMO) transmission and opportunistic beamforming for one or more user devices. In addition, the CQI can be used to determine the appropriate beam assignment or to update the beam pattern.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for blind detection of cell-specific reference signals. Methods and apparatus are provided for detecting a cell-specific reference signal (CRS) in an orthogonal frequency division multiplexed (OFDM) symbol by a user equipment (UE). The method generally includes predicting a current channel response of a current OFDM symbol based on a channel response of at least one previous OFDM symbol, estimating a noise power level of the current OFDM symbol, forming a log likelihood ratio (LLR) of two detection hypotheses based on the predicted current channel response and the estimated noise power level, comparing the LLR to a pre-determined threshold, and determining that at least one CRS is present in the current OFDM symbol based on the comparison.
