摘要

Systems and methods herein can synchronize 802.11ax Uplink (UL) and Downlink (DL) Orthogonal Frequency-Division Multiple Access (OFDMA) schedules between adjacent APs that have overlapping BSSs, which may not be solved by BSS coloring. The method includes several stages. First, the APs detect RF interference from APs with overlapping BSSs. Then, the APs conduct time synchronization between these APs. The various APs can then elect a master scheduler. The master scheduler creates and implements a master schedule between these APs to coordinate use of the radio resource.

說(shuō)明書(shū)

FIGS. 1A and 1B illustrate an example of an operating environment associated with aspects herein. The WLANs may comprise a basic service set (BSS) 100a, 100b that may include a master station or controller 101a, 101b, one or more APs 104a-104h, and one or more devices or stations (STAs) 106. The master station 101a, 101b may be an AP using the IEEE 802.11 protocol(s) to transmit and receive. Hereinafter, the term AP will be used to identify the controller 101, but the configurations may not be limited to the AP performing the functions described herein as a separate controller may also perform the functions.

The AP 104 may be a base station and may use other communications protocols as well as the IEEE 802.11 protocol. The IEEE 802.11 protocol may include using OFDMA, Time Division Multiple Access (TDMA), and/or code division multiple access (CDMA). The IEEE 802.11 protocol may include a multiple access technique. For example, the IEEE 802.11 protocol may include Space-Division Multiple Access (SDMA) and/or Multiple-User Multiple-Input Multiple-Output (MU-MIMO). An example configuration of the APs 104 and/or controllers 101 may be as shown in FIG. 6.
