Abstract: A communications apparatus includes an antenna module, multiple front-end signal processing circuits, and a processor. The antenna module transmits and receives RF signals for communicating with a network device and includes at least one antenna. Each front-end signal processing circuit is coupled to the antenna module for receiving the RF signals and processing the RF signals. The processor is coupled to the front-end signal processing circuits. The processor determines whether there is any downlink data to be received from the network device according to the content of received RF signals. When there is some downlink data to be received from the network device, the processor determines to turn off at least one front-end signal processing circuit and only use the remaining front-end signal processing circuits to process the received RF signals.

Abstract: A video processing method includes decoding a bitstream that includes a plurality of groups of pictures and each group of pictures comprises a frame sequence, determining whether a current frame of a current group of pictures to be displayed has macroblocks with forward reference to a previous frame of a previous group of pictures, wherein the current group of pictures is subsequent to the previous group of pictures, and displaying the current frame of the current group of pictures when the current frame has no macroblock with forward reference to the previous frame of the previous group of pictures. The previous frame of the previous group of pictures is determined to be referenced by the current frame of the current group of pictures according to information specified from the encoding of the current frame.

Abstract: Aspects of the disclosure provide an apparatus that includes a transceiver circuit and a baseband processing circuit. The transceiver circuit is configured to transmit signals that carry a data unit to another apparatus and receive signals that carry a response from the other apparatus. The baseband processing circuit is configured to provide a first digital stream to carry a data unit to the transceiver circuit for transmission, and provide a second digital stream to carry a portion of the data unit to the transceiver circuit for retransmission when the transceiver circuit receives a response that is indicative of a partial receiving failure of the data unit at the other apparatus.
