Abstract:
Aspects of the present disclosure provide example preamble formats with repeated signal (SIG) fields that may help provide backwards compatibility and help address the effects of larger delay spreads in various wireless bands (e.g., WiFi bands).
Abstract:
Systems, methods, and devices for concurrently allowing station-to-station transmissions and access point-to-station transmissions are described herein. In some aspects, a method comprises transmitting, to an access point, a request for an available channel frequency. The method further comprises receiving a coordination message from the access point. The coordination message may indicate that a first frequency channel is allocated for transmissions between a first device and a second device and that a second frequency channel is allocated for transmissions between a third device and a fourth device. The method further comprises transmitting a first data packet to the fourth device using the second frequency channel concurrently with a transmission of a second data packet between the first device and the second device using the first frequency channel.
Abstract:
Systems, methods, and devices for transmitting data are described herein. In some aspects, a method comprises generating a first message. The first message may comprise an allocation of a first station to a first frequency channel and a second station to a second frequency channel. The method further comprises transmitting the first message over the first frequency channel and the second frequency channel. The method further comprises transmitting, after transmission of the first message, a second message to the first station using the first frequency channel. The method further comprises transmitting, after transmission of the first message, a third message to the second station using the second frequency channel.
Abstract:
Systems and methods for aggregation of multiple physical protocol data units are disclosed. In one aspect, a method of transmitting a physical layer packet to a plurality of wireless devices is disclosed. The method includes generating a physical layer packet, the packet including a plurality of payloads, wherein at least one of the payloads comprises first data addressed to a first device and second data addressed to a second device, and wherein each payload is preceded by at least a signal field in the physical layer packet, and transmitting the physical layer packet.
Abstract:
Methods and apparatuses for communicating over a wireless communication network are disclosed herein. One method includes selecting one of a plurality of allocation schemas for allocation of wireless resources to wireless communication devices. The method further includes generating an allocation message comprising an identifier of the selected allocation schema and one or more allocations of wireless resources according to selected allocation schema. The method further includes transmitting the allocation message to one or more wireless communication devices.
Abstract:
In one aspect, a method of communicating via a wireless medium by a wireless communications apparatus within a network is provided. The method includes detecting an operating characteristic associated with a load of the network. The method further includes determining a process for adjusting a size of a contention window in response to a successful transmission of a frame based on the detected operating characteristic, the contention window being provided for determining a deferral period for deferring access to the wireless medium. The method further includes transmitting information indicating the process to one or more wireless devices operating within the network.
Abstract:
Systems and methods for communicating in a wireless communication system are described. Various processes for detecting and correcting communication errors described. In aspect a method in a wireless communication system is provided. The method includes transmitting a first packet from a sending device to a receiving device. The method further includes listening for an acknowledgement during a first time period. The method further includes transmitting a second packet to the receiving device after a second time period, when an acknowledgement is not received during the first time period. The second packet includes one or more error-correction codes operable to recover the first packet.
Abstract:
A method of wirelessly communicating a packet includes generating, at a first wireless device, a first packet including a first preamble decodable by a plurality of devices and a second preamble decodable by only a subset of the plurality of devices. The first preamble includes a first signal field. The second preamble includes a first training field. The method further includes transmitting the first packet concurrently with one or more second packets to be transmitted by wireless devices other than the first wireless device.
Abstract:
Systems, methods, and devices for wireless communication. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a receiver configured to receive a wireless signal comprising a packet. At least a portion of the wireless signal may be received over a channel with a channel bandwidth of at least approximately five hundred megahertz. The packet may be formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising at least one hundred and twenty-eight tones. The apparatus further comprises a processor configured to evaluate the wireless signal. The processor may comprise a transform module configured to convert the at least one OFDM symbol into a frequency domain signal.
Abstract:
