Abstract: Systems and methods described herein provide a centralized solution for interference mitigation that focuses on efficient spectrum management. Wireless Access Points (APs) collect interference measurements for wireless channels and generate corresponding interferer airtime estimates. The APs also determine Packet Error Rates (PERs) for wireless client devices currently being served via the channels by the APs. The APs send the interferer airtime measurements and the PERs to a centralized controller. If an interferer airtime estimate and a PER for a particular channel satisfy predefined threshold conditions, the controller modifies an allocation of wireless bandwidth for an AP that is currently using the channel and sends a message to the AP indicating how the allocation has been modified.

According to one method, a device under test including at least one processor simulates frame preemption by generating a plurality of simulated preempted frame fragments and an express frame. The test device deterministically orders, independently from MAC merge sublayer fragmentation and ordering, the simulated preempted frame fragments and the express frame for transmission to the DUT. The test device transmits the simulated preempted frame fragments and the express frame to the DUT in an order corresponding to the deterministic ordering. The test device receives a response of the DUT to the simulated preempted frame fragments and the express frame. The test device determines, based on the response of the DUT, whether the DUT operates in accordance with specifications for frame preemption.

Abstract: In an 802.11ax network with an access point, a trigger frame offers random resource units to nodes for data uplink communication to the access point. To dynamically adapt the contention mechanism used by the nodes to access the random resource units, the AP updates a correcting TBD parameter at each new TXOP and includes the updated adjusting parameter in the trigger frame for the next TXOP. The nodes use the TBD parameter to generate a local random RU backoff value from a contention window range, for contending for access to the random resource units. The TBD parameter may directly impact the contention window size CWO or boundaries values of a selection range from which CWO is selected.
