Abstract: Disclosed is a channel detection method applied to a wireless local area network device, including: measuring a channel before data are transmitted; and determining a Clear Channel Assessment (CCA) threshold according to a corresponding relation among a channel measurement result, transmitting power levels and channel access parameters, and judging whether a state of the channel is idle according to the CCA threshold. The present application further discloses a channel detection apparatus.

Abstract: Provided is a method for forwarding a multicast message, which includes that: a forwarding chip receives a multicast message, determines that the multicast message is a known multicast message, sends the known multicast message to a Central Processing Unit (CPU), deletes a CPU interface from an outbound interface list of a multicast forwarding table, updates the multicast forwarding table and a multicast state table according to a received multicast routing table, and determines that the multicast forwarding table is converged into a steady state according to the updated multicast state table. A device for forwarding a multicast message is provided, accordingly.

Abstract: Provided are data transmission methods and apparatuses, a primary node, and a secondary node. In the data transmission method, a data transmission opportunity is obtained; and a radio frame is sent to at least one secondary node, wherein a signalling field of the radio frame contains indication information used for indicating that the radio frame is transmitted via an Orthogonal Frequency Division Multiple Access (OFDMA) transmission mode.

Abstract: The present document discloses a data transmission method and a Station (STA). The data transmission method includes: a source STA has data to be sent, and detects, in a back-off process, that a radio channel is busy and a physical frame header part of a radio frame is successfully received; the source STA determines that a medium currently carrying wireless transmission can be multiplexed according to receiver Identification information carried in the received physical frame header part of the radio frame, and the source STA competes for a multiplexing transmission opportunity; and the source STA sends a radio frame to a destination STA after acquiring the multiplexing transmission opportunity.
