Abstract: A method includes: determining, by an AP from all STAs associated with the AP, a concurrent STA joining a concurrent group, and generating concurrent group information of the concurrent group; and sending the concurrent group information to another AP in a system other than the AP, so that a BSS to which the another AP belongs determines, according to the concurrent group information, to join the concurrent group, to eventually form the concurrent group. All concurrent STAs that are associated with the AP and that join the concurrent group perform channel contention within a concurrent time by using an increased target CCA threshold, to increase a possibility that the concurrent STAs send data, so that a system throughput is improved.

Abstract: Example radio link monitoring methods and apparatus are described. One example method includes performing radio link monitoring (RLM) in a second bandwidth part (BWP) by a terminal device. The terminal device receives first switching information from a network device that is used to indicate that an active BWP includes a first BWP, and switches from the second BWP to the first BWP based on the first switching information. The terminal device removes a measurement result obtained by performing RLM in the second BWP, where the measurement result includes a quantity N1 of one or more out of synchronization (OOS) states or a quantity N2 of one or more in synchronization (IS) states. RLM is performed in the first BWP.

Abstract: This application discloses an LDPC code-based decoding method and apparatus, and pertains to the field of communications technologies. In this application, n×L LLR values may be decoded based on a target element in a target basis matrix, and a non-target element in the target basis matrix is forbidden to participate in decoding the n×L LLR values. The non-target element is a zero matrix, and the LLR value does not change after the LLR value is processed based on the non-target element. Therefore, the non-target element in the target basis matrix is forbidden to participate in decoding. In this way, decoding of the LLR value is not affected. In addition, a decoding time overhead and an occupied resource are reduced and decoding performance is improved because the LLR value is no longer processed based on a non-target element.

Abstract: A wavelength tunable optical transmitter apparatus relates to the field of communications technologies and includes a plurality of multi-longitudinal mode lasers (1), a cyclic wavelength demultiplexer/multiplexer (2), and a reflector (3). The multi-longitudinal mode lasers output multi-longitudinal mode signals having a periodically repeated frequency interval, where the period is Δfmode. The cyclic wavelength demultiplexer/multiplexer performs periodically repeated filtering on the multi-longitudinal mode signals input by the multi-longitudinal mode lasers, to obtain single frequency signals, where a repetition period of a filter window is Δfband, Δfmode is different from Δfband, and Δfmode and Δfband are not in an integer-multiple relationship, and then, multiplexes the plurality of single frequency signals and outputs the multiplexed signal. The reflector reflects the multiplexed signal. The reflected multiplexed signal separately returns to the multi-longitudinal mode laser by using the cyclic wavelength demultiplexer/multiplexer again.
