TECHNICAL FIELD

An exemplary aspect is directed toward communications systems. More specifically an exemplary aspect is directed toward IEEE (Institute of Electrical and Electronics Engineers) 802.11 wireless communications systems.

BACKGROUND

Wireless systems employ processes to manage the radio resources of the wireless devices to optimize parameters including channelization, transmit power, etc. The management of the radio helps avoid or mitigate issues with signal interference, bandwidth contention, etc. Newer Wi-Fi standards allow for more bandwidth capacity for Wireless Local Area Network (WLAN). With wide channel bandwidths, e.g., up to 160 MHz, and very high data rates, higher throughput through the WLAN can be attained. However, usage of wide bandwidths contributes to high frequency reuse, which can cause more interference on at least some channels, among Basic Service Sets (BSSs) in a Radio Frequency (RF) neighborhood. Thus, The Access Points (APs) providing wireless access to the WLAN must carefully administer Radio Resource Management (RRM) to balance the higher bandwidth capacity and the increased interference potential (caused by overlapping spectrum) when selecting the higher bandwidths.

APs may rely on other communications technologies to connect to the rest of the network/Internet. One of the most common connections is an Ethernet switch, which may be directly connected to the AP. APs can also use other technologies as a backhaul, such as 5G networks or Data Over Cable Service Interface Specifications (DOCSIS). The realized capacity that the AP can provide to stations connected to the AP can be bottlenecked by the capacity of the switch and/or backhaul connection. For example, if the switch capacity is only 1 Gbps, then the stations connected to the AP cannot realize the full capacity of the 160 MHz bandwidth channels, which can support as much as 2.3 Gbps. Similarly, the 5G backhaul may have limited data rates, either from physical link capacity limits or from cellular service provider throttling the channel due to tiered plans.

With current RRM techniques, the switch and backhaul limits are not determined or allowed for in the bandwidth allocations, which can lead to excessively wide bandwidth selection, where APs and client stations cannot take advantage of the increased radio capacity, while also reducing the available wireless spectrum.

SUMMARY

Aspects herein can include systems and methods that analyze a bandwidth restriction in a communication stream of an Access Point (AP). Then, based on the bandwidth restriction, the AP can determine a lower amount of wireless bandwidth to provide to station wireless communicating to the AP. The AP can then modify a bandwidth allocation assigned to the station based on the lower amount of wireless bandwidth.
