  • Patent number: 10972993
    Abstract: Logic to “loosely” manage synch frame transmissions in a synch network via the devices synched to the network that implement the logic. Logic may distributedly adjust the frequency of attempting synch frame transmissions without estimating the size of the neighborhood. Logic in devices of a synch network to let each device maintain a Transmission Window (TW). Logic to determine the frequency of attempting synch frame transmissions based upon the TW. Logic to increase TW if the device detects a synch frame transmission. Logic to decrease TW if the device successfully transmits a synch frame. Logic to balance power consumption and discovery timing by adjusting the decrease in TW responsive to a synch transmission in relation to the increase in TW responsive to detection of a synch transmitted by another device.

  • Patent number: 10536903
    Abstract: Logic may comprise hardware and/or code to select a narrow band from a wider channel bandwidth. Logic of communications between devices may select, e.g., a 1 or 2 MHz sub-channel from a wider channel bandwidth such as 4, 8, and 16 MHz and transmit packets on the selected 1 or 2 MHz channel. For instance, a first device may comprise an access point and a second device may comprise a station such as a low power sensor or a meter that may, e.g., operate on battery power. Logic of the devices may facilitate a frequency selective transmission scheme. Logic of the access point may transmit sounding packets or control frames across the sub-channels of the wide bandwidth channel, facilitating selection by the stations of a sub-channel and subsequent communications on the sub-channel between the access point and the station.

  • Patent number: 10349405
    Abstract: Logic may coordinate communications of different types of wireless communications devices such as high power and low power wireless communications devices. Logic may coordinate communications by assigning time slots to a low power station (LP-STA) in a management frame such as a beacon transmitted by an access point (AP) associated with the LP-STA. Logic of the high power stations (HP-STAs) may receive the beacon and shepard logic of the HP-STA may defer transmissions by the HP-STA throughout the duration(s) indicated in the beacon from the AP. Logic of the LP-STA may comprise carrier sense multiple access with collision avoidance logic to determine when to transmit a communication. Shepard logic of an HP-STA may detect the communication from the LP-STA and defer transmission of communication during a time duration for the communication by the LP-STA.

  • Patent number: 10200974
    Abstract: Logic for collision mitigation between transmissions of wireless transmitters and receivers operating at different bandwidths. Logic of the receivers may be capable of receiving and detecting signals transmitted at narrower bandwidths. In several embodiments, the receivers comprise a clear channel assessment logic that implements a guard interval (or cyclic prefix) detector to detect transmissions at narrower bandwidths. For instance, a two MegaHertz (MHz) bandwidth receiver may implement a guard interval detector to detect 1 MHz bandwidth signals and a 16 MHz bandwidth receiver may implement logic to detect one or more 1 MHz bandwidth signals and any other combination of, e.g., 1, 2, 4, 8 MHz bandwidth signals. In many embodiments, the guard interval detector may be implemented to detect guard intervals on a channel designated as a primary channel as well as on one or more non-primary channels.

  • Patent number: 10177956
    Abstract: A wireless device may include processing circuitry that is configured to process a preamble of a packet, the preamble comprising a legacy portion comprising a legacy signal field (L-SIG) and a subsequent portion comprising a non-legacy signal field. The processing circuitry may be further configured to determine whether a symbol of the non-legacy signal field is modulated using binary phase shift keying (BPSK) or modulated using quadrature binary phase shift keying (OBPSK). The processing circuitry may be further configured to process the subsequent portion of the packet in accordance with a first packet format if the symbol of the non-legacy signal field is modulated using OBPSK, and to process the subsequent portion of the packet in accordance with a different packet format if the symbol of the non-legacy signal field is modulated using BPSK.

  • Publication number: 20180279263
    Abstract: Various embodiments are described for a trained data transmission for communication systems. A training phase may include a first wireless station exchanging medium reservation messages with a second wireless station to reserve a medium and to select a data transmission parameter. The data transmission parameter may include a modulation scheme and a forward error correction (FEC) coding rate. At least one of the medium reservation messages may include a duration field indicating a duration for which the medium is reserved. A first data phase may include sending data from the first wireless station to the second wireless station according to the selected data transmission parameter. A second data phase may then be performed without first repeating the training phase. The second data phase may include transmitting data from the first wireless station to a second wireless station according to the data transmission parameter.

  • Patent number: 10070433
    Abstract: A technology for a user equipment (UE) that is operable to communicate in an ad-hoc wireless multicast communications network is disclosed. Another UE can be selected to send a request to send (RTS) control frame to. The RTS control frame can be communicated to the other UE. The RTS control frame indicates that the UE requests to send a multicast data frame. A clear to send (CTS) message can be received from the other UE, indicating the UE is clear to send the multicast data frame. The multicast data frame can be transmitted by the UE to a selected group of UEs.

  • Publication number: 20180205805
    Abstract: Embodiments provide a new short beacon frame format and its operation with full beacon frame transmissions for wireless communications devices. Many embodiments comprise a medium access control (MAC) sublayer logic to build frames comprising the short beacon frame for a first communications device. In some embodiments, the MAC sublayer may determine a frame control field comprising a type field indicative of an extension frame and a subtype indicative of a short beacon. In further embodiments, the frame control field may comprise a service set identifier (SSID) control field, and a reserved field. Some embodiments may store the short beacon frame or frame format in memory, in logic, or in another manner that facilitates transmission of the short beacon frames. Some embodiments may receive and detect communications with the short beacon frames. Further embodiments may generate and transmit a communication with the short beacon frames.

    Abstract: Generally discussed herein are systems and apparatuses arranged to perform a Time-of-Flight (ToF) or Round Trip Time measurement. The disclosure also includes techniques of making and using the systems and apparatuses. According to an example a station (STA) can be arranged to perform a Time-of-Flight (ToF) measurement, the STA can include a transceiver arranged to transmit a hard constraint indicating a time window in which the STA is unavailable for performing the ToF measurement, and receive an action frame of the ToF measurement from another STA at a time that is outside the time window.
