Abstract:
Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a receiver of a relay is configured to receive a relay initiator frame and a data frame. A transmitter of the relay is configured to transmit an amplified version of the data frame at a same or substantially same time as a time that the data frame is received if the relay initiator frame is received prior to the data frame.
Abstract:
Systems, methods, and devices for registering a relay in a wireless communications network are described herein. In some aspects, a device is configured to operate as a relay and to transmit an association message. The association message comprises capabilities of the device and an indication of whether the device relays uplink traffic, downlink traffic, or both. An access point is configured to receive the association message to associate the device with the access point based on the association message and to transmit a beacon message to a station. The beacon message comprises an indication of whether the access point is associated with a relay.
Abstract:
Systems, methods, and devices for setting up a relay in a wireless communications network are described herein. In some aspects, a transmitter of a station is configured to transmit a relay request to an access point. The access point is configured to transmit a discovery request frame based on the relay request to at least one relay. Each of the at least one relay is configured to transmit a discovery message based on the discovery request frame to the station. A processor of the station is configured to select one relay of the at least one relay based on each received discovery message. The transmitter is further configured to transmit a message comprising an identification of the selected one relay of the at least one relay to the access point.
Abstract:
Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, an access point is configured to receive a request for relay connection and to transmit a message to at least one relay based on the received request for relay connection. The message comprises an instruction to transmit a setup response frame. A station is configured to transmit the request for relay connection to the access point and to select one of the at least one relay based on at least one setup response frame received from at least one of the at least one relay. The selected one of the at least one relay is configured to relay data packets between the station and the access point.
Abstract:
Systems, methods, and devices for securely communicating data are described herein. In some aspects, a station is configured to communicate with an access point. A relay includes an uncontrolled port and a controlled port. The relay is configured to forward association, authentication, and secure relay setup frames between the station and the access point through the uncontrolled port. The relay is configured to forward data packets between the station and the access point through the uncontrolled port once the station establishes a relay relationship with the relay.
Abstract:
Systems, methods, and devices for reducing collisions in a wireless communications network are described herein. In some aspects, a processor is configured to decrementing a value of a counter if a channel of a wireless communications network is idle for at least an extended slot time. The processor may be further configured to generate a polling request and allow the transmission of the polling request to an access point over the wireless communications network when the value of the counter reaches a threshold value.
Abstract:
Systems, methods, and devices for acknowledging communications from a plurality of wireless devices in a wireless network are described herein. In some embodiments, an access point for the wireless network transmits a group acknowledgment (ACK) to indicate whether communications (packets) from the plurality of wireless devices have been received or correctly decoded within some time interval. Each wireless device may have a different time interval associated with it. For some embodiments, the time interval for a wireless device is relative to when a previous group ACK was sent. A group ACK may include a bitmap. In some embodiments, the bitmap indicating whether a communication has been received or correctly decoded may be transmitted as part of a beacon.
Abstract:
A method for reduced overhead paging by an access point is described. The method includes assigning at least one paging identifier to at least one station. The method also includes partitioning a paging identifier space into paging identifier sets. The method further includes generating a paging message based on at least one of the paging identifier sets and the at least one paging identifier. The method additionally includes sending the paging message.
Abstract:
Systems, methods, and devices for communicating packets having a plurality of types are described herein. The sender or receiver-MAC address, depending on the packet direction, is substituted with a shorter local identifier in order to reduce packets' overhead.
Abstract:
Systems, methods, and devices for discovering a wireless communications network are described herein. In some aspects, a transmitter of a station is configured to transmit a probe request. The probe request is addressed to one of a wildcard service set identifier and a service set identifier of a service set in which a relay operates. A receiver of the station is configured to receive a probe request response from the relay. The probe response comprises an identification of an access point the relay is associated with and capabilities of the relay.
