Abstract: Crest Factor Reduction (CFR) parameters are determined for a dual band Power Amplifier (PA). A first band of the dual band PA is associated with a first Multi-Link Operation (MLO) link and a second band of the dual band PA is associated with a second MLO link. Determining the CFR parameters comprises determining based on a configuration of the first MLO link and the second MLO link. A first portion of the CFR parameters is provided to a first crest factor reduction block. First portion of the CFR parameters comprises a first clipping threshold associated with the first band and first filter coefficients associated with the first band. A second portion of the CFR parameters is provided to a second crest factor reduction block. The second portion of the CFR parameters comprises a second clipping threshold associated with the second band and second filter coefficients associated with the second band.

Abstract: Improved Radio Frequency (RF) performance by optimizing temperature may be provided. A plurality of heatmaps may be created associating a plurality of component heat characteristics, of a plurality of components of a device, with a plurality of pre-defined performance trade-off states. Next, a shortest path through the plurality of pre-defined performance trade-off states may be determined. The device may then be placed in successive ones of the plurality of pre-defined performance trade-off states according to the determined shortest path until a Transmit (TX) performance target is met.

Abstract: Optimal determination of wireless antenna configurations may be provided. A computing device may direct an antenna array of an Access Point (AP) to generate a wide beamwidth, to locate a cluster of two or more stations. Upon locating the cluster, the AP can narrow the beamwidth, and, with the narrower beamwidth, receive a key performance indicator (KPI) from at least one of the two or more stations in the cluster. The computing device may then generate a statistical model, based on the KPI and an antenna vector of the antenna array. Based on the statistical model, the computing device can determine a second antenna vector to optimize the KPI for one or more of the client stations. The computing device can then modify the antenna state of the AP to generate the determined antenna vector.

Abstract: Network traffic interference detection and management may be provided. An infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP may be detected, and information associated with the infringement event may be added to an infringement list, wherein the information includes a MAC address associated with the infringing AP. A controller, may receive the infringement list and notify the infringement event to the infringing AP. The infringing AP may determine whether a transmission associated with the infringement event is low latency and high priority. When the transmission is not low latency and high priority the infringing AP may modify future transmissions based on the notification. When the transmission is low latency and high priority the infringing AP may notify the controller that the transmission is low latency and high priority. The controller may then create a negotiation between the victim AP and the infringing AP, wherein the negotiation comprises managing future transmissions of the victim AP and the infringing AP.

Abstract: Ultra-Wideband (UWB) ranging and location tracking, and particularly an UWB antenna array system and methods for improving the accuracy for Phase-Difference-of-Arrival (PDOA) is provided. UWB ranging may include receiving a poll signal from a client via a first and second antenna. PDOA between the first and second antenna is determined based on the poll signal. A response signal is transmitted to the client, and a first portion of a final signal is received via the first antenna and a third antenna and a second portion of the final signal is received via the second and third antenna. PDOA between the first and third antenna is determined based on the first portion, and PDOA between the second and third antenna is determined based on the second portion. The client location is then determined based on the PDOAs.

Abstract: Optimal determination of transmit power level for MLDs in A Wireless Local Area Network (WLAN). An AP can establish synchronous downlink multi-link operations with another MLD. A first link and a second link between the AP and the MLD both operate in a same sub-band. The AP can then determine the same power level for both the first link and second link. After establishing the same power level, the AP can then determine a second power level for the first link and a third power level for the second link. The second power level is greater than the third power level. The AP can then provide the second power level for the first link and the third power level for the second link.
