Abstract: Embodiments of this disclosure disclose a multi-link communication method and a related apparatus. In a scenario in which simultaneous transmission and reception over a plurality of links is not supported, a multi-link device first sends a first physical layer protocol data unit (PPDU) over a first link, and then sends a second PPDU over a second link through channel contention, where an end time of the second PPDU is not later than an end time of the first PPDU. The method not only ensures fairness of multi-link access, but also can reduce an idle rate of the plurality of links.

Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a picture parameter set (PPS) in a PPS network abstraction layer (NAL) unit and a coded picture comprising a set of video coding layer (VCL) NAL units. A particular VCL NAL unit does not refer to the PPS NAL unit unless a value of a NAL unit header layer identifier (nuh_layer_id) of the PPS NAL unit is less than or equal to a value of a nuh_layer_id of the particular VCL NAL unit. The coded picture is decoded from the set of VCL NAL units based on the PPS in the PPS NAL unit to produce a decoded picture. The decoded picture is forwarded for display as part of a decoded video sequence.

Abstract: This application relates to a method for determining a length of an low-density parity-check (LDPC) code word in a ultra-wideband (UWB) system and a related apparatus. The method includes a communication apparatus that determines a length of an LDPC code based on a length of a to-be-encoded information bit. When the length of the information bit ranges from 0 to 324, a 648-bit LDPC code is selected. When the length of the information bit ranges from 325 to 648 or from 973 to 1296, a 1296-bit LDPC code is selected. When the length of the information bit ranges from 649 to 972, a 1944-bit LDPC code is selected. According to embodiments of this application, higher performance gain can be achieved.

Abstract: A transmission control method in a satellite communication system and a related apparatus are provided. A terminal may determine, through satellite selection, a target satellite with a strongest signal from at least one satellite in geosynchronous orbit. The terminal may determine a satellite transmission link direction based on location information of the terminal and location information of the target satellite and may further determine a radiation direction of a satellite antenna in the terminal based on geomagnetic data and attitude data of the terminal. The terminal may enable, by using the satellite transmission link direction and the radiation direction of the satellite antenna, the radiation direction of the satellite antenna in the terminal to be aligned with the target satellite. After aligning with the target satellite, the terminal may send a first data packet to the target satellite along the radiation direction of the satellite antenna.

Abstract: Example data processing methods and apparatus are described. In one example method, a control node estimates a data volume of result data obtained after a plurality of second computing nodes execute a data processing task in parallel. The control node determines a quantity of reduce tasks based on the data volume and memory information of a first computing node that executes a reduce task. Each of the plurality of second computing nodes partitions, based on the quantity of reduced tasks, the result data generated after the data processing task is executed, where each partition corresponds to one reduce task. The first computing node performs reduce processing on data obtained after partitioning is performed by the plurality of second computing nodes.
