Abstract: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.

Abstract: Systems, methods, and devices for wireless communication are described herein. In some aspects, a method for preventing multiple re-association attempts includes identifying a station, determining a back-off period for the identified station during which an access point will reject association requests from the station, and transmitting a message to the station, the message including the determined back-off period. The method may further include rejecting association requests from the identified station during the back-off period. The method may also include determining a timeout period for the identified station after which disassociation with the access point will occur. The message may further include the determined timeout period. The method may also include disassociating the identified station after the timeout period.

Abstract: Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, an access point receives an authentication request from a station. The access point transmits an authentication initiation request to an authentication server. The access point transmits an authentication response, which includes an estimated response delay, to the station after the authentication initiation request is transmitted to the authentication server. The estimated response delay may allow the station to transition from an awake state to a sleep state for a time based on the estimated response delay. The access point receives an authentication status from the authentication server. The access point receives an association request from the station after the station transitions from the sleep state to the awake state. The access point transmits the authentication status to the station in response to receiving the association request.

Abstract: A method includes determining, at a first transmitter, whether to permit reuse of a first transmit opportunity (TXOP) associated with a message. The method further includes sending a portion of the message from the first transmitter to a first receiver. The portion of the message indicates whether reuse, by a reuse transmitter, of the first TXOP is permitted. When reuse of the first TXOP is permitted, the reuse transmitter is permitted to send a second message while the first transmitter sends a second portion of the message to the first receiver during the first TXOP.

Abstract: Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a station transmits an authentication request to an access point and for the access point to transmit an authentication initiation request to an authentication server. The station receives an authentication response comprising an estimated response delay from the access point. The station transitions from an awake state to a sleep state for a duration of time based on the estimated response delay. The station transmits an association request to the access point after the duration of time and transitioning from the sleep state to the awake state. The station receives an association response from the access point, where the association response comprises an authentication status that indicates whether authentication with the authentication server is successful.
