Claim of US Patent No. 11,115,991


1. A method, comprising:sending, by an access point supporting both scheduling transmissions and contention- based transmissions, a scheduling request to a first scheduling server according to a data transmission requirement upon determining to perform the scheduling transmissions, the scheduling request requesting allocation of a first contention frequency band to the access point for performing the scheduling transmissions, wherein the scheduling request comprises frequency band bandwidth information of the first contention frequency band, and frequency band use time information of the first contention frequency band indicating how long the first contention frequency band is to be used;
obtaining, by the access point, an allocation of a second contention frequency band that is allocated by the first scheduling server to the access point according to a first spectrum list and the scheduling request, wherein the first spectrum list comprises frequency band use information of the access point and interference information of the access point;
performing, by the access point, a scheduling transmission using the second contention frequency band without listening on a channel in the second contention frequency band, wherein the second contention frequency band is determined by the first scheduling server, satisfies the scheduling request, is outside an interference frequency band range, and has an interference intensity lower than a preset threshold; and
after obtaining the second contention frequency band, providing, by the access point, a contention frequency of the second contention frequency band to a first station (STA) for use according to a transmission requirement of the first STA in a basic service set (BSS).
