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: 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 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: A wireless communication technique includes generating, by a wireless terminal, a transmission message that includes a preamble portion and a data portion. In this technique, transmission resources for the data portion are related to transmission resources for the preamble portion using a relationship rule. The wireless terminal transmits the transmission message to a network-side device during a random access procedure.

Abstract: A wireless communication method is described for managing packet data convergence protocol (PDCP) service data unit (SDU). The method can include receiving, at a first protocol layer of a first communication device, a first service data unit (SDU) and a second service data unit (SDU) for a source from a second protocol layer for transmission to a second communication device. The method can also include starting a first timer with a first initial value for the first SDU, and starting a second timer with a second initial value for the second SDU. The second initial value can be different from the first initial value in response to determining that the second SDU is to be routed differently from the first SDU to the second communication device.
