Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of connected discontinuous reception (C-DRX) by using a wireless device (e.g., a user equipment (UE)) with a second receiver. A wireless device with two receivers may place one receiver in a low power mode and take the receiver out of the low power mode in response to a signal received from a serving base station (BS) of the wireless device. A BS may direct a wireless device to enter a low power DRX (LP-DRX) mode or enhanced DRX mode having longer low power cycles than a non-enhanced DRX mode, and the wireless device may place a primary receiver in a low power mode in response to the directive from the BS. Other aspects, embodiments, and features are also claimed and disclosed.

Abstract: Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. A method operational in a receiver device, includes monitoring one or more repurposed channels within a television broadcast frequency spectrum for data waveforms, wherein waveforms of different bandwidths coexist within the one or more repurposed channels, and at least a larger waveform has a first bandwidth larger than a channel bandwidth for each repurposed channel. The method also includes receiving a waveform over a repurposed channel from among the one or more repurposed channels, wherein the received waveform has a second bandwidth smaller than the channel bandwidth. The method further includes processing the received waveform by applying a downclocking factor to a clock of the receiver device that causes the receiver device to process the received waveform according to the second bandwidth to obtain a data payload from the received waveform.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to ultra low-power paging frames for wake up and discovery. One example apparatus for wireless communications generally includes at least one interface configured to receive via a first radio and a second radio, wherein the at least one interface receives a paging frame from another apparatus via the second radio while the first radio is in a first power state that is lower than a second power state of the second radio; and a processing system configured to take one or more actions based on a command field included in the paging frame.

Abstract: A method of line coding is disclosed that limits error propagation in a decision feedback equalizer (DFE) of a receiving device. A communications device receives a set of bits to be transmitted over a channel and divides the set of bits into a plurality of blocks based, at least in part, on a line coding scheme. The device then encodes each of the blocks of bits into a corresponding block of symbols based on the line coding scheme. Specifically, the line coding scheme has a non-uniform coding efficiency, wherein a first bit or a last bit of each block of bits is mapped to a single data symbol. For some embodiments, the line coding scheme may be a ternary line coding scheme that maps a block of 3k+1 bits to a corresponding block of 2k+1 symbols, where k is an integer greater than 1.

Abstract: In a method of scheduling frames, a first channel of a plurality of channels is selected for a first frame. The first frame is sent across a media-independent interface to a physical-layer device for transmission on the first channel. A data rate of the media-independent interface is greater than a data rate of the physical-layer device for the first channel. After the first frame is sent across the media-independent interface, subsequent sending of frames for the first channel across the media-independent interface is disabled for a period of time that is based at least in part on rate adaption from the data rate of the media-independent interface to the data rate of the physical-layer device for the first channel.

Abstract: A method includes transmitting, from an electronic device in a neighbor awareness network (NAN) via a first wireless protocol, a wake up message indicating discovery information associated with a second wireless protocol. The method further includes communicating information via the NAN using the second wireless protocol after transmitting the wake up message.

Abstract: A spatio-temporal random voting scheme is provided that incorporates location distribution, spatial randomness, and temporal randomness in the collection of information from a plurality of sensing devices within the cognitive network. The region is divided into a plurality of sectors, where each sector is a portion of the region. A subset of sectors is selected from the plurality of sectors in the region to provide spatial randomness. A device is randomly selected from each sector in the subset of sectors to provide additional spatial randomness to the information collection process. Temporal randomness may be introduced by randomly selecting a timeslot within a sensing window period in which devices are to scan a frequency spectrum band to determine if a signal energy above a threshold is detected. Sensing reports are then collected from the selected sensing devices and used to determine whether the frequency spectrum band is available or in use.
