Abstract: The method includes: an intercepting station detecting a first radio signal of a third-party station and updating a local network allocation vector and/or response indication deferral; triggering a channel contention access procedure when determining that a second radio signal of the third-party station meets a spatial orthogonal condition, and then completing data transmission within updated time. In the case that the network allocation vector or response indication deferral is not 0, the third-party station ignoring or resetting the network allocation vector or the response indication deferral when determining that a sector transmission in a transmission initiated by the station is orthogonal with a transmission space to be carried out by itself, the third-party station initiating a contention and starting the spatial orthogonal transmission within a duration indicated by the updated network allocation vector or the response indication deferral.

Abstract: The disclosure provides a communication processing method and an apparatus for communication processing in a wireless network. The method comprises: a master node of the wireless network acquires channel allocation information, wherein the channel allocation information is used for indicating a channel resource needed for communication between the master node and subnodes or between the subnodes, and the channel allocation information carries an access parameter used for indicating a channel access backoff policy of the channel resource; and the master node sends, on a first frequency band, the channel allocation information to the subnodes. With the disclosure, problems in related art that frequency band types of channels are indistinguishable, no definition is provided in terms of bandwidth operations and channel utilization is low are solved. It is further achieved that different operations may be implemented on different frequency bands in a wireless network and a variable communication bandwidth is supported, which is beneficial for full use of channels and avoids mutual interference.

Abstract: Provided are a method and a device for sending traffic indication information. In the method, an AP sends a radio frame to multiple STAs associated with the AP, wherein the radio frame carries an indication field, and the indication field is used to indicate whether the radio frame carries traffic indication virtual bitmap information. According to the technical solution provided, in the case where the AP has no unicast cache data for any station, multiple STAs associated with the AP can know whether the AP has their respective unicast cache data to be sent.
