Abstract: A correlation magnitude signal is divided into a plurality of samples at a sequence of intervals over a symbol time, where the correlation signal corresponds to a magnitude of a correlation of a signal received at a receiver device with a known sequence. A sample with a highest magnitude value for the symbol time is selected from the plurality of samples. A symbol-synchronization signal that corresponds to an interval of the sequence of intervals containing the sample with the highest magnitude value is provided to a rake receiver system.

Abstract: A first communication device in a wireless local area network (WLAN) determines one or more frequency division, full duplex (FDFD) parameters for an FDFD operation that includes FDFD communications via a first frequency segment and a second frequency segment. The first frequency segment and the second frequency segment are separated by a gap in frequency. The one or more FDFD parameters include a parameter indicating a duration of the FDFD operation. The first communication device generates a communication frame that includes one or more indications of the one or more FDFD parameters. The one or more indications in the communication frame include an indication of the duration of the FDFD operation. The first communication device transmits the communication frame to prompt a plurality of second communication devices to participate in the FDFD operation.

Abstract: A method for operation of a first communication device in a wireless local area network (WLAN) communication channel between the first communication device and one or more second communication devices is described for a WLAN communication channel that has a plurality of component channels. A first component channel of the plurality of component channels is designated as a first primary channel and a second component channel of the plurality of component channels is designated as a second primary channel by the first communication device. A backoff timer that corresponds to the second component channel is suspended by the first communication device while utilizing the first component channel and without utilizing the second component channel. The backoff timer is resumed by the first communication device when utilization of the first component channel has completed.

Abstract: A method for accessing a shared medium includes receiving, at a first device associated with a first basic service set (BSS), a packet from a second device associated with a second BSS. The packet includes an indication of a duration for which the shared medium is expected to be busy. The method includes setting, at the first device, a first counter for an inter-BSS channel access to the duration in response to the second BSS being different than the first BSS and in response to the duration being greater than a current value of the first counter. The method includes setting, at the first device, a second counter for an intra-BSS channel access to the duration in response to the second BSS being the same as the first BSS and irrespective of whether the duration indicated in the packet is greater than a current value of the second counter.

Abstract: Embodiments described herein provide a mechanism including the configuration and use of the wakeup request (WUR) frame to announce the transmission of a management frame. Specifically, the WUR frame is configured with information indicating whether the incoming management frame includes new BSS operation information, based on which the low power device may determine whether to wake up the 802.11 WLAN receiver to receive the management frame.

Abstract: A first communication device determines an amount of data queued at the first communication device for transmission. When a control field is to be generated according to a first format, the first communication device determines a scaling value (SV) and an unscaled value (UV) corresponding to the determined amount of data queued for transmission such that a result of SV multiplied by BV indicates the determined amount of data queued for transmission, and generates the control field to include i) a scaling factor subfield set to indicate the SV, and ii) an unscaled queue size subfield set to indicate the BV. When the control field is to be generated according to a second format, the first communication generates the control field to include a queue size subfield set to indicate the determined amount of data queued for transmission and such that the control field does not include the scaling factor subfield.

Abstract: Embodiments described herein provide a method for performing beamforming in a multiple-user-multiple-input-multiple-output (MUMIMO) system. At a MUMIMO access point, MUMIMO data may be received from a station of a plurality of stations. Uplink channel state information may be obtained, from the MUMIMO data, representing an uplink channel between the station and the MUMIMO access point. The uplink channel includes signals transmitted from the station using the second number of antennas. Downlink channel state information may be computed, based on the uplink channel state information, representing a downlink channel between the MUMIMO access point and the station.

Abstract: The present disclosure includes systems and techniques relating to wireless local area network devices. A described technique include accessing a data stream intended for transmission to a single wireless communication device; multiplexing the data stream to two or more radio pathways to produce a data packet; generating, via the two or more radio pathways, two or more different portions of the data packet based on an aggregated capacity of two or more wireless channels that are associated with the two or more radio pathways, the two or more radio pathways being respectively configured to use two or more groups of orthogonal frequency division multiplexing (OFDM) subcarriers to generate the two or more different portions of the data packet; and transmitting the data packet to the single wireless communication device by concurrent transmissions of the two or more different portions via the two or more wireless channels.

Abstract: The present disclosure includes systems and techniques relating to controlling access to a shared communication medium in a wireless communication system. In some implementations, a first communication device associated with a first basic service set (BSS) identified by a first BSS indicator receives a data unit transmitted by a second communication device. The data unit includes (i) a second BSS indicator indicating a second BSS associated with the second communication device and (ii) a duration indicator indicating a duration of time for which the shared communication medium is expected to be busy. An inter-BSS channel access counter is set based on the duration of time indicated by the duration indicator if the second BSS is different from the first BSS. An intra-BSS channel access counter is set based on the duration of time indicated by the duration indicator if the second BSS is the same as the first BSS.
