Abstract: Embodiments of the invention provide a contention method. The contention method includes: receiving, by an access point, an uplink frame transmitted by a station; transmitting, by the access point, a frame responding to the uplink frame. The frame responding to the uplink frame is used to acknowledge the uplink frame and trigger the station to enter the next channel contention period. The contention method can acknowledge the uplink frame and trigger the station to enter the next channel contention period.

Abstract: Embodiments of the disclosure provide a method, an apparatus, and a device for controlling wireless transmission. A first access point in a first system selects, from access point devices in a second system, one access point as a second access point to which the first access point is attached, and connects to the second access point to send first information to a network device. In so doing, the network device determines, according to the first information and second information that is sent by a user device via an access point to which the user device is attached, a transmission mode and a transmission bandwidth between the first access point and the user device, thereby solving a problem of cross timeslot interference that occurs when wireless local area network systems of different types have an overlapping coverage area and are not synchronized.

Abstract: The present invention provides a data transmission method. In the method of the present invention, a station receives an indication frame sent by an access point, where the indication frame is used for allocating a designated random contention channel; a channel state of the designated random contention channel is sensed according to the indication frame; and the station sends data on the designated random contention channel after it is detected that the designated random contention channel is in an idle state. Because in the method of the present invention, a designated random contention channel is allocated to a station, the station can send data on the designated random contention channel, contention among stations is reduced and a time for a station to be connected to a random contention channel is reduced.

Abstract: The present invention provides an uplink data receiving method and apparatus of wireless transceiver device. The method includes: obtaining a wireless channel state parameter of neighboring wireless transceiver device of the device; obtaining downlink data sent by the neighboring wireless transceiver device in a cross slot with the device; reestablishing an interference signal according to the wireless channel state parameter and the downlink data; and removing the interference signal from an uplink data signal received by the device. By reestablishing the interference signal of the neighboring wireless transceiver device on an uplink data signal received by the device in the cross slot, and removing the interference signal from the uplink data signal received by the device, cross slot interference may be eliminated without influencing the flexible allocation of a dynamic TDD system on wireless resources.

Abstract: The present invention discloses a method, an apparatus and a wireless terminal for channel switch, and the method includes: sending information on the target channel and a first channel within the preset channel soft switch time interval after a channel switch announcement instruction is sent on the first channel when the first channel needs to be switched, and stopping sending information on the first channel if the preset channel soft switch time interval ends. By means of above method, the probability of switch failure for the user may be reduced in a scenario with frequent channel switch.

Abstract: Embodiments of the invention provide an OFDMA contention method and an access point. The OFDMA contention method includes: receiving, by an access point, a contention request frame transmitted by a station over a subchannel, and judging whether a sum of a number of stations succeeding in a contention in a current channel contention period and a number of stations succeeding in a historic contention is minor than a preset threshold; if yes, triggering the station to enter a next channel contention period, and repeatedly executing the steps of the receiving and the judging, until a number of stations succeeding in contentions is greater than or equal to the preset threshold. The OFDMA contention method and the access point can increase the number of the stations succeeding in contentions, thereby improving the throughput of an OFDMA system.
