FIELD: radio engineering, communication.SUBSTANCE: embodiments of the present invention provide a backoff method and device used for a lower priority access category AC. The method comprises the following steps: when the lower priority AC and another AC in the same station STA obtain a transmission opportunity TXOP at the same time and an internal collision occurs, detecting a TXOP sharing state of the lower priority AC; and executing backoff of the lower priority AC according to the detected TXOP sharing state.EFFECT: performing backoff by detecting a transmission opportunity (TXOP) sharing state.17 cl, 7 dwg, 2 tbl |
