OFDMA CONTENTION METHOD AND ACCESS POINT

摘要

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.

1. An orthogonal frequency division multiplexing access (OFDMA) contention method, comprising:
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, by the access point, the contention request frame transmitted by the station over the subchannel, and the judging whether the sum of the number of stations succeeding in the contention in the current channel contention period and the number of stations succeeding in the historic contention is minor than the preset threshold, until a number of stations succeeding in contentions is greater than or equal to the preset threshold.
