  • Patent number: 10693585
    Abstract: A method of link adaptation is described including establishing, using a first serving point, a multi-user full duplex mode wherein the multi-user full duplex mode enables a downlink to a first wireless device and an uplink from a second wireless device. The first serving point requests from the first wireless device a first channel quality indicator indicating channel quality between the serving point and the first wireless device in a full duplex time period and a second channel quality indicator indicating channel quality between the serving point and the first wireless device in non-full duplex time period. The full duplex mode is evaluated using the first and second channel quality indicators. At least one parameter of the full duplex mode is adjusted based on the evaluating.

  • Patent number: 10575295
    Abstract: A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

MAC components operate essential in accordance with the 802.11 standard. Signals at 2.4/5 GHz intermediate frequency (IF) output from an IF module are upconverted to an RF mmWave spectrum. The RF signals are routed to different subsector antennas and/or polarizations of a subsector antenna in order to direct the RF mmWave signal to a desired destination. Beamforming by the physical structures of antennas, direct the RF signals to a particular subsector. The combination of allocating resources within the MAC, processing within the MBI module before being upconverting to RF, together with signal switching of the RF signals, determines the destination to which signals are to be transmitted and the source from which signals are to be received.

A wireless device (e.g., cellular telephone) is able to communicate with a base station in a cell of the cellular network over a non-cellular interface via another wireless device in a cell through the use of multi-hopping. A wireless device may request permission to communicate with the base station over a non-cellular interface via hopping off another wireless device when its signal strength is below a threshold. Alternatively, a wireless device may receive a request to communicate with the base station over a non-cellular interface via hopping off the wireless device that sent the request when that wireless device has excess capacity in its bandwidth with the base station. By enabling wireless devices to communicate with a base station in such a manner, the effective capacity of the cellular network is expanded and the effective capacity of the cellular network is improved.

  • Patent number: 10257108
    Abstract: A full-duplex (FD) capable access point (AP) of a wireless basic service set (BSS) that includes a plurality of stations (STAs) is configured to implement opportunistic FD downlink (DL) transmissions to a non-FD capable STA in the BSS when decoding uplink (UL) data from a UL STA in the BSS. While decoding the UL data, the AP selects a DL STA from a queue of DL STAs based on a predetermined FD DL transmission rate from the AP to the DL STA while the AP is decoding the UL data from the UL STA. The AP then causes an amount of data to be transmitted as an FD transmission to the selected DL STA while the processor is decoding the data from the UL STA.

  • Patent number: 10236925
    Abstract: A front-end circuit includes an antenna terminal, front-end terminals (Pfe1, Pfe2), a circulator, and frequency-variable filters. The circulator sends transmission signals of communication bands of a frequency division duplex system and a time division duplex system from the front-end terminal (Pfe1) to the antenna terminal. The circulator sends a reception signal from the antenna terminal to the front-end terminal (Pfe2). The frequency-variable filter is connected between the front-end terminal (Pfe1) and the circulator, passes transmission signals of the frequency division duplex system and the time division duplex system, and attenuates signals other than the above transmission signals. The frequency-variable filter is connected between the circulator and the front-end terminal (Pfe2), passes a reception signal of the frequency division duplex system, and attenuates signals other than the above reception signal.
