Abstract: Techniques for peer-to-peer (P2P) transmission in a multi-user (MU) multiple-input-multiple-output (MIMO) environment. A first wireless station (STA), including a plurality of radio antennas, identifies channel state information (CSI) relating to a connection between the first STA and a wireless access point (AP). The first STA determines connection information relating to a MU MIMO P2P connection between the first STA and a second STA. The first STA generates a plurality of values relating to precoding for the plurality of radio antennas, based on the CSI and the connection information. The first STA and the second STA exchange data over the P2P connection, using the plurality of values relating to precoding.

Abstract: Techniques for neighborhood management between WiFi and unlicensed spectrum radios. A wireless access point (AP), including a first radio, identifies a neighboring second radio operating using at least a portion of an unlicensed radio spectrum, based on a time that the AP receives a transmission from the second radio using a frequency within the unlicensed radio spectrum. Transmission between the first radio and the second radio is synchronized by identifying a clock offset between a first clock relating to the first radio and a second clock relating to the second radio.

Abstract: Aspects described herein include a method for use with an access point (AP). The method comprises inspecting control frames received from a rogue AP, characterizing an intrusion by the rogue AP using one or more spatial reuse parameters included in the control frames, and selecting a defensive posture for the AP based on the characterization.

Abstract: A method includes transmitting a message over a first link using a first radio of a plurality of radios of a multi-link device and in response to determining that the message was not properly received, selecting a second radio of the plurality of radios of the multi-link device. A second link of the second radio provides a higher probability than the first link that the message will be properly received. The method also includes retransmitting the message over the second link using the second radio.

Abstract: A method includes instructing, by a WiFi access node, a first device to communicate using an uplink frequency band with a first uplink power. The method also includes instructing, by the WiFi access node, a second device to communicate using the uplink frequency band with a second uplink power different from the first uplink power.

Abstract: Optimization of radio communications of a wireless network of a local site may be provided. A probe frame or an association frame may be received from a Client Device (CD) operating in the local site that identifies at least one operating class and Multi-Link (ML) capability information of the CD. Channel information of at least one Access Point (AP) having ML capability in the local site may be embedded in a probe response frame or in an association response frame based on the at least one operating class and the ML capability information of the CD. The probe response frame or the association response frame that includes the channel information of the at least one AP having ML capability in the local site may be transmitted, as unicast, to the CD.

Abstract: Techniques for distributed computation are provided. A plurality of edge computing devices available to execute a computing task for a client device is identified, and a first latency of transmitting data among the plurality of edge computing devices is determined. A second latency of transmitting data from the client device to the plurality of edge computing devices is determined, and a set of edge computing devices, from the plurality of edge computing devices, is determined to execute the computing task based at least in part on the first and second latencies. Execution of the computing task is facilitated using the set of edge computing devices, where the client device transmits a portion of the computing task directly to each edge computing device of the set of edge computing devices.

Abstract: Embodiments for preliminary antenna configuration for a radio in an access point are described. A preliminary antenna configuration with a first number of antennas transmitting at a first power level based on a maximum transmission power for the radio is used to determine a second antenna configuration based on network level factors, where the second antenna configuration includes a second number of antennas. The second antenna configuration is used to determine a third antenna configuration from the second antenna configuration, where the third antenna configuration includes a third number of antennas transmitting at a third power level based on a client transmission factors for a plurality of client devices connected to the access point. The third antenna configuration is used to transmit network traffic from the access point to the plurality of client devices using the third antenna configuration.
