Communication devices and OBO counter value taking method thereof, electronic equipment and storage medium

Abstract

The invention discloses an OBO counter value taking method of communication devices. The method comprises the steps: acquiring a Beacon message sent by an AP, wherein the Beacon message comprises the frequency unused rate of the RU in a previous trigger frame and the number of associated communication devices; calculating the number of unallocated communication devices which are not allocated to the RU in the associated communication devices according to the number of the associated communication devices; calculating the number of competitive RUs allocated to the associated communication devices by the AP in the previous trigger frame according to the frequency unutilization rate; acquiring the number of the RUs which are not successfully competed in the competitive RUs distributed to the associated communication equipment by the AP in the previous trigger frame; and determining the value of an OBO counter according to the number of the unallocated communication devices, the number of the competitive RUs and the number of the RUs which do not compete successfully. The invention further discloses the communication devices, electronic equipment and a computer readable storage medium. By adopting the embodiment of the invention, the value of the OBO counter can be determined according to the resource utilization condition of the current AP, so that the associated communication devices can increase the opportunity of successful RU competition.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication device and an OBO counter value acquisition method thereof, an electronic device and a storage medium. Background technique [0002] The 802.11ax protocol introduces OFDMA (Orthogonal Frequency Division Multiple Access) technology, that is, multiple access technology, so that AP (Access Point, wireless access point) and STA (Station, client) can support random RU (Resource Unit, resource unit) access. Based on this, the AP needs to maintain the OFDMA contention window OCW required for random access to the RU, and the STA needs to maintain the OBO counter required for the random access to the RU. [0003] When a STA competes for RU, at first the STA will select a random number as the value of the OBO counter, and then the AP will send a contention type trigger frame, which is used to trigger an uplink RU access, which includes determining Determinis...

Problems solved by technology

Therefore, the value of the OBO counter determines when the STA performs RU random access. That is to say, the value of the OBO counter within the appropriate range can increase the chance of STA competition success. However, the 802.11ax protocol does not specify the specific value of the OBO counter. instead of using random numbers, STAs will use the same random number generation method in different environments, which will easily cause access conflicts, resulting in a low STA competition success rate
