Example Embodiment

[0031] around.

[0032] figure 1 is a schematic flowchart of a channel competition method provided by an embodiment of the present invention, such as figure 1 shown, including:

[0033] 101. The first device detects whether the target channel includes an idle subchannel in an idle state. If the detection target channel includes an idle subchannel in an idle state, perform step 102. If the detection target channel does not include an idle subchannel in an idle state. , go to step 101.

[0034] 102. The first device sends a request frame to the second device on a target subchannel; the target subchannel is at least one subchannel included in the idle subchannel;

[0035] 103. When the first device receives the response frame sent by the second device, the first device determines that the competition for the target subchannel is successful; the response frame is the second device's response to the request frame made in response to the frame.

Abstract

Disclosed is a channel competition method, comprising: a first device detecting whether a target channel contains an idle sub-channel which is in an idle state or not, and if so, sending a request frame to a second device over a target sub-channel, wherein the target sub-channel is at least one sub-channel which is contained in the idle sub-channel; and when the first device receives a response frame sent by the second device, the first device determining that the competition for the target sub-channel is successful, wherein the response frame is a response frame issued by the second device to the request frame. Correspondingly, further provided is a corresponding device. The embodiments of the present invention can improve the spectrum efficiency of a network system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a channel competition method and equipment Background technique [0002] In the wireless local area network (Wireless Local Area Networks, WLAN) system, the data transmission of the station (Station, STA) adopts the carrier sense multiple access / collision avoidance (Carrier sense multiple access with collision avoidance, CSMA / CA) mechanism for channel In this mechanism, if a STA competes successfully in this mechanism, the STA can use the entire frequency band of the Basic Service Set (BSS) to which the STA belongs to transmit data. If there is interference in one of the subbands in these frequency bands, then Transmissions may fail over the entire frequency band. [0003] At present, the above problems are mainly solved through the back-off mechanism. In the back-off mechanism, the access point (Access Point, AP) or STA maintains a back-off timer. The back-off timer is set as ...
