Abstract: During operation, transmitters in the electronic device provide first and second FMCW radar signals, where carrier frequencies of the first and the second FMCW radar signals have a predefined variation as a function of time over a predefined frequency range, and the predefined variation as a function of time of a second carrier frequency of the second FMCW radar signal has a predefined delay relative to the predefined variation as a function of time of a first carrier frequency of the first FMCW radar signal. Furthermore, at least a receiver in the electronic device receives first and second reflected FMCW radar signals within a bandwidth of the receiver, where, at a given time, a frequency difference between carrier frequencies of the first and the second reflected FMCW radar signals, which corresponds to the predefined delay, is less than the bandwidth (and which may be less than a predefined value).

Abstract: A circuit board in an electronic device includes a first set of transmit antennas and a first set of receive antennas arranged along an azimuth direction, and a second set of transmit antennas and a second set of receive antennas arranged along a direction that includes components in the azimuth direction and an elevation direction. Moreover, separations between adjacent transmit antennas in the first or second set of transmit antennas along the azimuth direction may be greater than one half of the fundamental wavelength. Furthermore, separations between adjacent receive antennas in the first or second set of receive antennas along the azimuth direction may equal one half of the fundamental wavelength. Additionally, adjacent antennas in the second set of transmit antennas and the second set of receive antennas may be partially offset from each other and partially overlap with each other along the elevation direction.

Abstract: Dynamically control of receive diversity switching in a user equipment (UE) is disclosed. By dynamically controlling the switching between enabling and disabling the receive diversity, power consumption in UEs, such as smart phones and other mobile devices may be reduced. Control is based, at least in part, on measurements for data activity performed by the UE. When the UE finds measurements that would suggest data activity, the UE will switch to enable a receive diversity state when conditions are available for the switch. Similarly, when the UE finds measurements that would suggest data inactivity, the UE will switch to disable the receive diversity state when conditions are available for the switch.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided for prioritizing the performance of measurements during measurement gaps and the reception of multicast/broadcast content. The apparatus receives a configuration from a serving cell to perform a measurement during a measurement gap of a unicast service while in a connected mode. In addition, the apparatus determines whether to refrain from leaving the serving cell on a first frequency and performing the measurement on a second frequency of a neighboring cell in order to receive multicast/broadcast content associated with a multicast/broadcast service during the measurement gap.

Abstract: User experiences on wireless devices are affected by communication, computation, and user interface capabilities. Another key performance indicator of a wireless device is its battery life. A method, algorithm and apparatus for improving the communication, computation and user interface capabilities of a mobile device is disclosed, which requires the expenditure of less energy and increases battery life. The trade-off between battery life and user experience related to the communication capability is managed by a protocol stack power optimization algorithm that optimally allocates energy resources. The power management algorithm inputs and combines measurements made at various layers of the protocol stack to selectively control a set of actions impacting energy usage. The algorithm maps from a set of measurements to a set of actions that provides the best trade-off between user experience and energy consumption.

Abstract: Techniques for scaling symbols to account for large abrupt changes in received power at a user equipment (UE) are described. The UE performs AGC on received samples to obtain input samples. The UE processes (e.g., CDMA demodulates) the input samples to obtain first symbols. The UE determines the power of the input samples and derives a symbol gain based on (e.g., inversely related to) the power of the input samples. The UE scales the first symbols with the symbol gain to obtain detected data symbols having approximately constant amplitude, even with large abrupt changes in the power of the input samples. The UE estimates signal amplitude and noise variance based on the detected data symbols, computes LLRs for code bits of the detected data symbols based on the signal amplitude and noise variance, and decodes the LLRs to obtain decoded data.

Abstract: Techniques for controlling transmit power are described. Due to link imbalance, a downlink (DL) serving cell may have the best downlink for a UE, and an uplink (UL) serving cell may have the best uplink for the UE. In one design of UL power control, the UE receives first and second UL TPC commands from the DL and UL serving cells, respectively, and adjusts its transmit power based on these UL TPC commands and in accordance with an OR-of-the-UPs rule. In one design of DL power control, the UE generates a DL TPC command based on received signal qualities of both the DL and UL serving cells. In another design, power control is performed independently for the DL and UL serving cells. The UE generates a separate DL TPC command for each cell, which adjusts its transmit power based on the DL TPC command for that cell.
