Abstract: A detailed design of an LTE Link Adaptation function for LTE uplink is disclosed. A new approach for adapting SINR backoff in OLLA is used when serving non-time-sensitive radio bearers without target BLER constraint. A sub-optimal scheduler is also disclosed wherein the SINR measurements at the ILLA input are updated on each TTI for the UEs scheduled in that sub-frame for future UL transmission with a fresher interference measurement from the sub-frame preceding by 8 ms the actual transmission sub-frame. This allows for exploitation of a correlation peak of the interference resulting from HARQ retransmissions. A schedule incorporating these features improves upon, with a minor complexity increase, the spectral efficiency performance of a low-complexity baseline scheduler only based on SINR updates at SRS rate.

Abstract: Embodiments of a power line communication (PLC) transmitter device for overlapping priority contention windows are presented. A processor is configured to perform a physical channel sense operation to detect an idle channel on a PLC network. A transmitter transmits a normal priority data packet on the channel during a high priority contention window. In another embodiment, a Normal Priority Contention Window (NPCW) is allowed to overlap with a High Priority Contention Window (HPCW). The minimum contention window for the normal priority frames (i.e., NPCW) is equal to or longer than the contention window for high priority frames (i.e., HPCW). By making the NPCW longer than the HPCW, the high priority frames will have a better chance than normal priority frames to get access to the channel on transmission reattempts.

Abstract: Channel state information (CSI) feedback in a wireless communication system is disclosed. A precoding matrix is generated for multi-antenna transmission based on precoding matrix indicator (PMI) feedback, wherein the PMI indicates a choice of precoding matrix derived from a matrix multiplication of two matrices from a first codebook and a second codebook. In one embodiment, the first codebook comprises at least a first precoding matrix constructed with a first group of adjacent Discrete-Fourier-Transform (DFT) vectors. In another embodiment, the first codebook comprises at least a second precoding matrix constructed with a second group of uniformly distributed non-adjacent DFT vectors.

Abstract: Topology discovery of a target system having a plurality of components coupled with a scan topology may be performed by driving a low logic value on the data input signal and a data output signal of the scan topology. An input data value and an output data value for each of the plurality of components is sampled and recorded. A low logic value is then scanned through the scan path and recorded at each component. The scan topology may be determined based on the recorded data values and the recorded scan values.

Abstract: Transmitting a acknowledge/not acknowledge (ACK/NACK) response in a wireless cellular network by mapping the data value into a cyclic shifted version of a reference signal. A subframe is formed with a plurality of symbols with certain symbols designated as reference signal (RS) symbols. The receiver and transmitter both know when an ACK/NACK response is expected. If an ACK/NACK response is not expected, then an RS is inserted in the duration of symbols designated as RS symbols. If an ACK/NACK response is expected, then the ACK/NACK response is embedded in one or more of the symbols designated as RS symbols. The subframe is transmitted to a receiver, and the receiver can determine the ACK/NACK value in the RS symbol, if present, and also use the RS symbol for coherent demodulation of a CQI (channel quality indicator) or data.

Abstract: An integrated circuit is formed by forming an isolation mesa over a single crystal substrate which includes silicon, and forming a first epitaxial layer on the substrate by a selective epitaxial process so that a top surface of the first epitaxial layer is coplanar with the top surface of the isolation mesa. A non-selective epitaxial process forms single-crystalline silicon-based semiconductor material on the first epitaxial layer and non-crystalline silicon-based material on the isolation mesa. A cap layer is formed over the second epitaxial layer, and a radiantly-induced recrystallization process causes the non-crystalline silicon-based material to form single-crystalline semiconductor over the isolation mesa.

Abstract: An adaptive threshold approach is applied to detect true touch signals and filter out increased noise signals. More specifically, statistics regarding the signals from a touch screen are used to create a touch signal threshold that changes with the statistics of the touch signals. Accordingly, the threshold can automatically move higher in high noise situations and lower in low noise situations. So configured, fewer noise signals are erroneously interpreted as touches for the device associated with the touch screen.
