  • Patent number: 10764874
    Abstract: An access point generates a trigger frame to trigger an uplink multi-user (MU) transmission by multiple client stations. The access point generates the trigger frame to include a common information field and multiple per-station information fields. The access point generates the common information field to include (i) a subfield that indicates a bandwidth of the uplink MU transmission, and (ii) information that indicates a guard interval and a long training field (LTF) mode to be used by the multiple client stations for the uplink MU transmission, and generates each per-station field to include respective frequency allocation information that indicates respective frequency resources to be used by the respective client station for the uplink MU transmission. The access point transmits the trigger frame to the multiple client stations to trigger the uplink MU transmission by the multiple client stations.

  • Patent number: 10756864
    Abstract: According to one embodiment of the present invention, a method by which a terminal transmits a signal in a wireless communication system comprises the steps of: receiving timing advance (TA) information on a self-contained subframe having all of a downlink control region, a downlink data region, a guard period (GP) for transmission/reception switching, and an uplink control region; and transmitting uplink control information by advancing transmission timing corresponding to the uplink control region by the time length indicated by the TA information, wherein, when the time length indicated by the TA information is shorter than a predetermined magnitude, the terminal can first transmit a specific uplink signal, and then transmit the uplink control information in a GP remaining period remaining after completion of the transmission/reception switching.

  • Patent number: 10757713
    Abstract: Mobile devices often use orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, physical distance between the mobile device and a signal source for positioning and other environmental factors can influence the signal strength of received signals. Received signals at the mobile device that are stronger may drown out the weaker signals, particularly when two signal sources occupy the same symbol. In traditional OFDM, a signal source transmits the same symbol for each positioning occasion, so a weaker signal may never be detected over a stronger signal, reducing the accuracy of the positioning calculations. Described herein are systems and methods for using a pattern to vary the designated symbol for each signal source in a wireless network so that a weaker signal from a signal source may be detected on at least some of the positioning occasions.

  • Patent number: 10693595
    Abstract: In a serial communication interface with transceivers that run on different clocks, an ACK transmit FIFO is used to track packets transmitted, and an ACK receive queue is used to track ACK bits for received packets. The ACK receive queue contains a number of entries, and training for the transceivers begins transmitting ACK bits from the ACK receive queue once the ACK receive queue has multiple valid ACK bits. When the ACK receive queue is less than a lower threshold, an ACK compensation mechanism sends one or more packets that make the ACK receive queue grow. When the ACK receive queue is more than an upper threshold, the ACK compensation mechanism sends one or more packets that make the ACK receive queue shrink. The combination of the ACK receive queue and the ACK compensation mechanism allow dynamically compensating for the different clocks of the two transceivers.

  • Patent number: 10681123
    Abstract: The application layer of a first wireless device may be configured to receive a ranging request indication from a MAC layer of the first wireless device, determine whether the MAC layer should respond to the ranging request, and send a ranging response to the MAC layer with an indication of whether to respond to the ranging request. The MAC layer may be configured to decode a ranging set-up request from a second wireless device, where the ranging set-up request comprises time slots. If an auto-response is set to false, send a ranging request indication to the application layer and receive from the application layer a ranging response, and if the auto-response is set to true or the ranging response indicates the MAC layer should respond to the ranging set-up request, select a time slot, and encode a ranging response with an indication of the selected time slot.

  • Patent number: 10616053
    Abstract: A reconfigurable triplexer that can support more frequency bands than a traditional triplexer is disclosed. For example, the reconfigurable triplexer can handle frequencies of several hundred megahertz up to 10 gigahertz. Further, certain implementations of the reconfigurable multiplexer can reduce or eliminate frequency dead zones that exist with traditional multiplexers. The reconfigurable triplexer includes a multi-stage filter bank capable of supporting a number of frequency bands and a bypass circuit that enables the triplexer to support a variety of sets of frequencies. For instance, unlike traditional triplexers, the reconfigurable triplexer can support both frequency bands with relatively narrow spacing and frequency bands with relatively wide spacing. Further, the inclusion of the bypass circuit enables the reduction or elimination of dead zones between supported frequencies.
