  • Patent number: 11381264
    Abstract: System-aware radio frequency (RF) front ends for wireless communication systems are provided. High complexity communication systems, such as Third Generation Partnership Project (3GPP) fifth generation (5G)-new radio (NR) systems, impose severe board area, volume, thermal and interference penalties on wireless devices. In the case of 5G-NR, this is due to the number of bands to be supported, the instantaneous bandwidth and spectral efficiency among other parameters. Other communications systems can involve high modulation of other parameters that similarly impose such penalties. Embodiments described herein provide a co-designed RF front end architecture that utilizes system knowledge (e.g., from baseband or other digital control circuitry, from antenna feedback, etc.) to dynamically adjust the parameters of various RF front-end components. System-aware RF front ends are thus able to improve and optimize performance criteria (e.g., to reduce the above penalties in complex communications systems).

  • Patent number: 11337247
    Abstract: Provided are a terminal, a base station and a signal transmission control method whereby a response signal can be efficiently transmitted when the terminal receives downstream allocation control information via an R-PDCCH. An extraction unit receives downstream control information via one of a first downstream control channel, which is transmitted by use of one or more control channel elements (CCE) associated with an upstream control channel resource, and a second downstream control channel different from the first downstream control channel, and also receives data via a data channel. A control unit selects, from resources associated with CCE and from particular resources reported by a base station, an upstream control channel resource to be used in transmission of the response signal, and controls the transmission of the response signal.

    Abstract: A base station includes a millimeter wave communication unit coupled to an impulse radio ultra-wideband (IR-UWB) communication unit. The millimeter wave communication unit is capable of being wirelessly coupled to user-equipment using a millimeter wave communication link. Based on a determination as to whether the user-equipment is configured for IR-UWB ranging and localization, an IR-UWB communication link is established between the base station and user-equipment for IR-UWB ranging and localization. When the IR-UWB communication link is established for IR-UWB ranging and localization, the ranging and localization associated with the millimeter wave communication unit is disabled and the millimeter wave communication link is used for data communication maximizing throughput by utilizing localization and ranging information provided by the IR-UWB communication link.
