    Abstract: The present document provides a method for avoiding downlink data collision, an Access Point (AP) and a Station (STA). The method for avoiding downlink data collision includes: an AP receiving a radio frame for inquiring whether the AP has a Bufferable Unit (BU) of an STA transmitted by the STA; and after determining that there is a BU of the STA and the BU is larger than a predetermined threshold, the AP exchanging radio frames with the STA to reserve a channel, and transmitting the BU to the STA after succeeding in reserving the channel. The method can guarantee the fairness among various STAs and the reasonable utilization of channel resources, thus avoiding the collision; furthermore, the channel reservation frame transmitted by the AP can reserve a longer period of time, i.e. a plurality of BUs can be transmitted to the STA at a time, thus saving the link overhead.

    Abstract: A method of setup a protection mechanism for scheduled transmissions to multiple stations is introduced. Through transmitting a control frame addressing to multiple stations for immediate simultaneous responses, the transmitter would know the stations that are ready for receiving the scheduled data frames and schedule the packet for those stations. Combining the transmission of the control frame with the power saving mechanism would allow triggering a group of power saving stations to wake up at same for receiving the control frame and scheduled user data frames. A new mechanism of simultaneous group responses to the control frame with orthogonal identifier information for individual station is provided to uniquely identify the responding stations.

    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.
