Embodiment 1

[0127] The AP divides the Beacon Interval or a specified period of time into multiple time intervals. It is assumed that the AP divides the Beacon Interval into 4 time intervals, and each time interval can be equal or unequal in length. Such as Figure 8 as shown, Figure 8 It is a schematic diagram of contention access time interval division and combination patterns according to Embodiment 1 of the present invention. Figure 8 Among them, "1" indicates that the use is allowed, "0" indicates that the use is not allowed, and the pattern "1010" indicates the time interval that is allowed to be used corresponding to a specific access level. The AP sends time interval configuration information (same as the above indication message) in the Beacon frame, such as the number of time intervals, the length of each time interval, and so on.

[0128] The AP combines each time interval in a certain format to form several patterns (same as the above-mentioned contention access time interv...

Embodiment 2

[0147] The AP divides the Beacon Interval into multiple time intervals, such as Figure 8 As shown, and each time interval is combined in a certain format to form several patterns, and each pattern corresponds to a contention access time interval level. In this embodiment, it is assumed that the AP divides the Beacon Interval into 4 time intervals, and each time interval may be equal or unequal in length. Each bit corresponds to a time interval, and its value of "1" indicates that contention access can be performed within this time interval, and "0" indicates that contention access cannot be performed within this time interval. The 4 time intervals are correspondingly represented by 4 bits, and a total of 16 combinations are formed. For example, "1010" indicates that contention access is available in the first and third time intervals.

[0148] The AP configures the contention access interval level of the corresponding AC in the EDCA parameter set. Alternatively, the AP and...

Embodiment 3

[0152] Figure 11 is a schematic diagram of contention access time interval division and pattern according to Embodiment 3 of the present invention, Figure 11 Among them, "access level 1" indicates that the access level is the first level, and only the data of the highest access level is allowed to compete for sending; "access level 2" indicates that the access level is the second level, and only the highest access level is allowed It competes with the second-level data to send; "Access Level 3" indicates that the access level is the third level, and only the data with the highest access level, the second level, and the third level are allowed to compete for transmission; "Access Level 4" Indicates that the access level is the fourth level, and data contention of all access levels is allowed to be sent. The AP divides the Beacon Interval into multiple time intervals, such as Figure 11 As shown in , the access level information of the contention access time interval is mark...

Abstract

The present invention provides a method and apparatus for sending a radio frame. The method comprises: dividing, by a first station, one or more predetermined intervals or one or more predetermined time periods within the predetermined intervals into a predetermined number of competitive access time intervals, wherein the competitive access time intervals are configured for the first station to competitively send a first radio frame and / or for one or more second stations to competitively send a second radio frame; dividing, by the first station, an access class for the competitive access time intervals; and informing, by the first station, the second station of an indicating message, wherein the indicating message contains divided access class information of the competitive access time intervals, and the access class information is used for assisting the second station to select a competitive access time interval used during competitive sending of the second ratio frame. The problem of lower controllability of a station in the related art is solved, thereby achieving the effect of improving the controllability of the station.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a wireless frame sending method and device. Background technique [0002] At present, with the explosive application of wireless local area network (Wireless Local Area Network, referred to as WLAN) network, the deployment of WLAN network is becoming more and more dense, and the network load is also increasing. More seriously, the efficiency of the WLAN network will show an obvious downward trend, and simply increasing the rate cannot solve this problem. Therefore, the IEEE standardization organization has set up relevant task groups dedicated to solving WLAN network efficiency issues. Among them, improving user experience is an important goal, and how to ensure the service quality of users or services has attracted extensive attention and research. [0003] In related technologies, an access point (abbreviated as AP) and multiple stations (stations, referred to as STA) associ...
