    摘要： According to one or more embodiments, a playback device is provided. The device includes processing circuitry configured to receive a video stream including a plurality of video packets, where each of the plurality of video packets is associated with a respective video timestamp value. The playback device is further configured to store at least one of the plurality of video packets in a jitter buffer, and to adjust each of the respective video timestamp values by a respective delay value, where each of the respective delay values is either a dynamic delay value based on a first condition being satisfied or a fixed delay value based on a second condition being satisfied. The playback device is further configured to play the video stream according to the adjusted video timestamp values for reduced initial delay at the jitter buffer.

    摘要： A method in a first wireless device (WD) supporting wireless communication with a second WD is described. A plurality of wireless packets is received from the second WD including at least a first wireless packet. At least another wireless packet of the plurality of wireless packets is one of a retry packet and a repeat packet of the first packet. Each wireless packet of the plurality of wireless packets includes a plurality of bits and a first group of bits. For each received wireless packet, the plurality of bits corresponding to the received wireless packet is de-spread, and the first group of bits is correlated with a predetermined group of bits. The method further includes performing a majority vote based on the correlation of the first group of bits of each received wireless packet and creating a corrected packet based in part on the majority vote.

    摘要： Apparatuses and methods are disclosed for optimizing an L2-L1 interface. In some embodiments, a method for a network node includes grouping, at an open systems interconnection, OSI, layer 2, L2, codeblocks, CBs, based at least in part on a hardware property associated with an OSI layer 1, L1, processing engine; and sending the grouped CBs to the OSI L1 processing engine. In some embodiments, a method for a network node includes receiving, by an open systems interconnection, OSI, layer 1, L1, processing engine, a group of codeblocks, CBs, the CBs being grouped together based at least in part on a hardware property associated with the OSI L1 processing engine; and performing CB group-level encoding on at least the received group of CBs.

    摘要： In some embodiments, an authentication device is provided. The authentication device configured to determine that the wearable device is authorized to participate in the premises security system, cause transmission of a first security token that is usable to validate that the wearable device is authorized to participate in the premises security system, in response to the status update, request the first security token from the wearable device, validate that the wearable device is authorized to participate in the premises security system based at least in part on the first security token received from the wearable device and in response to validating that the wearable device is authorized to participate in the premises security system, cause transmission of a second security token to the wearable device where the second security token is usable to trigger a premises security system action.
