Abstract: Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power.

Abstract translation: 通过牺牲时间和/或频率分集来提供低功率发射机和/或接收机设备，以换取更低的功耗。 当信道条件指示时间和/或频率扩展对于传输是不必要的时，发射机可以进入其中使用时间选通方案或时间重复方案执行传输的功率节约模式。 在时间选通方案中，符号只传输一次，而不是多次，但是传输功率增加。 在时间重复方案中，相同符号的副本在不同的符号传输周期上以相同频率发送多次，而不是在不同的符号传输周期上在不同的频率上重发。 因此，可以生成符号一次并存储以用于随后的重传，从而允许一些发送器/接收器链组件可以以较低的占空比或处理速度操作以节省功率。

Abstract: A method, system and computer program product for a wireless mobile display digital interface (WMDDI) association procedure that allows establishing and joining more than one multicast group to facilitate the interoperability of multiple client devices based on host and client capabilities. The protocol provides for the exchange and update of capabilities and multicast addresses for layered multicast transmission applications. The system is used for interoperating devices with different capabilities and provides for efficient transmissions by using different multicast addresses mapped to different layers of a bitstream. The protocol adapts to changes in capabilities, in joining/releasing of multicast addresses and in link quality.

Abstract: Certain aspects of the present disclosure propose computer-program products for discovery of source or sink devices and their capabilities, prior to establishing a link such as a tunneled direct link setup (TDLS) link. The established link may be used for different applications such as Wi-Fi Display session with the desired source or sink device. The proposed computer-program product may also be applied to devices that utilize peer to peer communication.

Abstract: A tile concept allows independent encoding and decoding of regions of the video frames combined with changes in the way that the coded tiles are packetized and queued for transport. After the coded tile network abstraction layer (NAL) units are packetized into MPEG-TS frames, the more important tile data is put in the network abstraction layer at the head of the queue while the less important data is inserted later in the queue. Audio can also be accorded high priority. For a given link bandwidth/latency environment, the important data is transmitted first and the less important data can be discarded at the transmitter with less impact on the user perceived quality.
