IPC: H04W12/06
Abstract: An embodiment method includes receiving, by an access point (AP), a first authentication request from a station (STA) that requests authentication of the STA, transmitting, by the AP, a second authentication request to a server that requests including extensible authentication protocol (EAP) authentication signaling to verify mutual possession of a shared key between the STA and the server, and receiving, by the AP, a first authentication response from the server in response to the second authentication request. The first authentication response includes an indication that authentication of the STA was successful. The method further includes transmitting, by the AP, a second authentication response to the STA, and receiving, by the AP, an association request that includes a message integrity code (MIC) from the STA.

Abstract: System and method embodiments are provided for pausing data transmission in a full-duplex wireless network. Embodiments eliminate the deadlocks in the full duplex MAC layer and improve the system efficiency. In an embodiment, a method in a wirelessly enabled and full duplex enabled network component for pausing an ongoing data transmission includes beginning a transmission, with the network component, of first data to a first station; determining, with the network component, that transmission of a second data to a second station is required before completion of the transmission of the first data to the first station; transmitting, with the network component, a pause indicator to the first station notifying the first station that transmission of the first data will be paused; transmitting, with the network component, the second data to the second station; and resuming transmitting, with the network component, the first data to the first station.
