Abstract: A three-dimensional integrated circuit (3D-IC) architecture incorporates multiple layers, each layer including at least one die and at least one switch to connect the dies on the different layers. In some aspects, a power distribution network (PDN) is routed from a first layer through the switches to supply power to at least one other layer, thereby reducing routing congestion on the layers. The switches can be placed around the periphery of an IC package to improve heat dissipation (e.g., by improving heat transfer from the center to the edge of the IC package). The switches can be used for routing test signals and/or other signals between layers, thereby improving test functionality and/or fault recovery.

Abstract: Methods, systems, and devices are describe for signaling protocols for device-to-device discovery operations in a wireless communication system. A user equipment (UE) may be communicating with a serving base station using a first frequency in a first frequency band. The UE may transmit, to the serving base station, information associated with performing a discovery scan procedure on a second frequency in a second frequency band during a discovery scan interval. The first frequency may be different from the second frequency. The UE may identify a capability to skip one or more downlink transmissions from the serving base station during the discovery scan interval.

Abstract: Assistance data for indoor positioning is generated with vertical access areas, such as stairs, elevators, and escalators, identified along with predicted vertical movement models for the vertical access area. The predicted vertical movement models provide probabilities of movement to different floors by the vertical access areas. The assistance data may be generated by acquiring a floor plan data for a structure having multiple floors and analyzing the floor plan data to detect vertical access areas. The predicted vertical movement model for the vertical access area may then be generated and included in the assistance data along with the vertical access area. Mobile devices using the assistance data may provide vertical access area feedback information that may be used to modify the assistance data. For example, the probability of movement to different floors by a vertical access area may be modified, or additional vertical access areas identified.

Abstract: The disclosure relates to a collaborative demand-based dual-mode Wi-Fi network control framework that may optimize wireless power and performance on wireless devices that may support multiple Wi-Fi networking technologies. In particular, a high performance Wi-Fi link may be reserved to services or applications that have substantial quality of service (QoS) requirements and conventional Wi-Fi links may be utilized to transfer data for services or applications that have typical performance requirements. For example, bandwidth requirements associated with forward traffic may be measured according to sizes and latency requirements associated with the forward traffic and the appropriate Wi-Fi networking mode may be controlled according to the forward traffic bandwidth requirements in combination with the average bandwidth and average retransmission rate associated with the conventional Wi-Fi links, among other factors.

Abstract: Certain aspects of the present disclosure relate to a technique for touch temperature management of a wireless communications device based on power dissipated over time, and possibly internal temperature readings. For example, the information about power dissipated over time can be utilized along with monitored internal temperatures of a device's internal circuitry to reduce transmit power and/or data rates as required in order to keep a surface temperature of the wireless device below a specified limit. A knowledge of how the device's touch temperature varies with the dissipated power and a knowledge of the power dissipation history can be utilized to determine when to reduce the transmit power in order to avoid overheating (e.g., exceeding the touch temperature limit).

Abstract: A first receiver device receives a first pilot signal from a first transmitter device and a second pilot signal from a second transmitter device. The second pilot signal indicates that the second transmitter device intends to transmit a second traffic signal. The first receiver device determines a transmission rate for the first transmitter device as a function of the received signal strength of the first pilot and a predicted amount of the total interference to be perceived by the first receiver device. The predicted amount of the total interference being determined as a function of a SIC success probability. The transmission rate is sent to the first transmitter device. The first receiver device predicts whether the second traffic signal can be decoded and subtracted before the first receiver device decodes the first traffic signal to be transmitted by the first transmitter device as a function of the SIC success probability.

Abstract: Disclosed embodiments pertain to the measurement of heart rate in the presence of motion and noise. Spectral peaks in measurements by an optical sensor are compared with spectral peaks obtained from a motion sensor signal measurements, to obtain a fundamental frequency in the optical sensor signal, where the fundamental frequency is associated with a user's heart rate. A first heart rate may be estimated based on the fundamental frequency. A variety of quality metrics may be determined for the first heart rate estimate. A second estimated heart rate may be determined based by processing a frequency domain representation of the optical sensor signal based on a frequency domain representation of the motion sensor signal. One or more of the previously determined quality metrics may be dynamically adjusted based on a comparison of first and second estimated heart rates.

Abstract: Techniques for multiplexing and transmitting multiple data streams are described. Transmission of the multiple data streams occurs in “super-frames”. Each super-frame has a predetermined time duration and is further divided into multiple (e.g., four) frames. Each data block for each data stream is outer encoded to generate a corresponding code block. Each code block is partitioned into multiple subblocks, and each data packet in each code block is inner encoded and modulated to generate modulation symbols for the packet. The multiple subblocks for each code block are transmitted in the multiple frames of the same super-frame, one subblock per frame. Each data stream is allocated a number of transmission units in each super-frame and is assigned specific transmission units to achieve efficient packing. A wireless device can select and receive individual data streams.

Abstract: Techniques for mitigating interference in a wireless communication network are described. A terminal may desire to communicate with a weaker serving base station and may observe high interference from a strong interfering base station. The two base stations may be asynchronous and have different frame timing. In an aspect, high interference may be mitigated by having the interfering base station reserve downlink and/or uplink resources. The interfering base station may transmit at a low power level or not at all on the reserved downlink resources to reduce interference to the terminal. Terminals served by the interfering base station may transmit at a low power level or not at all on the reserved uplink resources to reduce interference at the serving base station. The terminal may then be able to communicate with the serving base station.

Abstract: Techniques are described for sub-prediction unit (PU) based motion prediction for video coding in HEVC and 3D-HEVC. In one example, the techniques include an advanced temporal motion vector prediction (TMVP) mode to predict sub-PUs of a PU in single layer coding for which motion vector refinement may be allowed. The advanced TMVP mode includes determining motion vectors for the PU in at least two stages to derive motion information for the PU that includes different motion vectors and reference indices for each of the sub-PUs of the PU. In another example, the techniques include storing separate motion information derived for each sub-PU of a current PU predicted using a sub-PU backward view synthesis prediction (BVSP) mode even after motion compensation is performed. The additional motion information stored for the current PU may be used to predict subsequent PUs for which the current PU is a neighboring block.

Once trained, these DNNs are used to predict underlying events in noisy audio to extract therefrom features that enable the separation of the underlying audio events from the noisy components thereof.
