1. A method for determining a contention window, which is performed at an access point and comprises:
acquiring buffer status reports of one or more stations and resource unit allocation status of the access point; and
determining contention window parameters of the contention window according to the buffer status reports and the resource unit allocation status,
wherein the contention window parameters comprise:
a maximum contention window value,
a minimum contention window value, and
a reserved field value, and
wherein the reserved field value is configured to indicate that stations associated and not associated with the access point select, as a corresponding contention window value for initializing an OFDMA back-off (OBO) counter, one of:
the maximum contention window value or
the minimum contention window value of the contention window,
wherein a value of the reserved field value indicates that the stations associated or not associated with the access point select the maximum contention window value as the corresponding contention window value; and
wherein another value of the reserved field value indicates that the stations associated or not associated with the access point select the minimum contention window value as the corresponding contention window value.
