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 compressing block acknowledgment (ACK) frames/packets are described herein. In some aspects, a method of communicating in a wireless network includes generating a compressed block acknowledgment frame comprising one or more local addresses. The method further includes transmitting the compressed block acknowledgment frame.
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 and methods for low overhead paging in a wireless communications network are described herein. In some aspects, an apparatus for wireless communication includes a receiver and a processor. The receiver receives a request from a first device. The request indicates a first period of a plurality of periods corresponding to a periodicity for transmitting paging messages. The processor assigns the first device to a group scheduled to receive paging messages at most every first period based on the request and determines a start time for transmitting paging messages to the first device based on schedules for transmitting paging messages to a plurality of other devices. In other aspects, an apparatus for wireless communication includes a processor and memory. The processor derives an information sub-unit from an information unit associated with a paging message, compresses the information sub-unit, and generates a second information unit associated with the method of compression.
Abstract:
Systems and methods for communicating in a wireless communication system are described. Various processes for reducing the initial link set up time are described. In one aspect, a method in a wireless communication system is provided. The method includes receiving, at a device, at least two different access request messages each for establishing a link with the device. The method further includes determining a period of time for transmitting access response messages in response to the received access request messages. The method further includes reserving a period of transmission time on a channel for transmitting the access response messages for establishing the link, the reservation based at least in part on the determined period of time. The method further includes transmitting the access response messages during the reserved period of time.
Abstract:
Systems, methods, and devices for communicating packets having a plurality of types are described herein. In some aspects, the packets include a compressed header. In one embodiment, a compression protocol is selected from a plurality of compression protocols to compress a first packet header. The packet may contain a second packet header, which may include information indicative of the compression protocol used to compress the first packet header. The packet may be transmitted, including the first packet header which is compressed using the selected compression protocol.
Abstract:
A method includes receiving, at a first wireless device from a second wireless device, a signal (SIG) unit including a first field. The method also includes determining whether the first field has a particular value that is indicative of a zero-length payload and decoding the SIG unit based at least in part on the determination.
Abstract:
One aspect of the disclosure provides a method for wireless communication by a station or wireless device. The method includes waking from a sleep state. Further, the method includes determining an availability of a transmission medium. In addition, in response to determining that the transmission medium is not available, the method can include determining a sleep time period, entering a second sleep state based on the sleep time period, and freezing a backoff counter for the duration of the second sleep state.
Abstract:
A method includes assigning a flow identifier to a flow that includes a plurality of packets. The method also includes generating a head packet of the plurality of packets. The head packet includes one or more header information fields that are associated with the flow identifier. The method further includes generating at least one data packet of the plurality of packets. The at least one data packet includes packet specific information and the flow identifier instead of the one or more header information fields. The method further includes transmitting the head packet. The method further includes, in response to detecting a successful receipt of the head packet, transmitting the at least one data packet.
Abstract:
Calibration coefficients are combined to provide more robust calibration. In some implementations, calibration coefficients are generated by acquiring two or more sets of calibration coefficients that are associated with different periods of time, different receive devices, or some other condition. These different sets of calibration coefficients are then combined using maximal ratio combining or some other suitable technique. The resulting combined calibration coefficients are used to calibrate implicit channel estimates.
