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.
Abstract:
A sleeping method and device are disclosed in the disclosure. The method comprises: a station confirms a first sleeping time for the station to enter a long sleep; the station informs an access point the first sleeping time; the station enters a long sleep according to the first sleeping time. In the disclosure, the station informs the first sleeping time to the access point, which enables the access point to acquire the first sleeping time of the station and cache data for the station, and at the same time, the access point may acquire the state of the station, which saves the cost for sending service indication information.
Abstract:
Methods, systems, and devices for resource indication and selection schemes in wireless communication are described. In one aspect, a wireless communication method is provided to include: performing, by a first device, a first communication of a resource pre-occupation information (RPI) with a second device using a dedicated resource pre-occupied channel or control channel, and wherein when a pre-occupied resource is transmitted at a time ‘n,’ the first communication is performed i) before a time ‘n-X,’ wherein X is an integer not less than 0, or ii) during a time window ending before the time ‘n.’

In one embodiment, a method for performing sidelink communications, includes: receiving, by a first wireless communication device, a first message from a first wireless communication node; determining, by the first wireless communication device, at least one first synchronization reference according to the first message; selecting, by the first wireless communication device, one of the at least one first synchronization reference as a second synchronization reference for receiving a sidelink communication signal; and performing the sidelink communications with the second wireless communication device according to the second synchronization reference, wherein the first message comprises configuration information for the sidelink communication.
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.
