4 results about "Ultra wide bandwidth" patented technology

Techniques related to ultra-wide-bandwidth (UWB) transmission mechanisms in wireless communications are described. A device (e.g., an access point (AP)) establishes a basic service set (BSS) on a primary link and a secondary link. The device then performs an aggregated bandwidth operation with one or more stations (STAs). The aggregated bandwidth of the primary link and the secondary link depends on the channel availability of each of the primary link and the secondary link.

Methods and systems for communication technology in which a fifth generation (5G) communication system supporting a higher data transfer rate after a fourth generation (4G) system is converged with Internet of Things (IoT) technology are provided. A method performed by a terminal in a wireless communication system includes receiving, from a base station, a radio resource control (RRC) message including a configuration of at least one frequency band and a configuration of a primary frequency band for the terminal, wherein the configuration of the at least one frequency band includes at least one of a subcarrier spacing, a cyclic prefix, and information on a frequency domain location and a bandwidth of the at least one frequency band; monitoring a control channel on the primary frequency band from the base station; and receiving, from the base station, a downlink control information indicating an active frequency band among the at least one frequency band based on the control channel.

The utility model provides an ultra-wide bandwidth dual-frequency combiner. The ultra-wide bandwidth dual-frequency combiner comprises a main shell, a high-frequency band-pass assembly and a low-frequency band-pass assembly. The main shell is provided with a high-frequency resonant cavity and a low-frequency resonant cavity, the two components are adjacently arranged, and the resonant cavities are communicated at the combined output end. The low-frequency band-pass component comprises a band-shaped main body, a 90-degree bent three-section band-shaped bent part and a plurality of resonance branches, two ends of the band-shaped main body are respectively connected with a low-frequency input end and a combined output end, the bent part extends a transmission path to adjust equivalent inductance, and compared with a traditional linear structure, the filter network parameters can be flexibly optimized; resonance branches of different areas expand the out-of-band suppression range, and the filtering characteristic is improved. Wherein the passband of the high-frequency band-pass assembly is 4800-5000MHz, the passband of the low-frequency assembly is 700-3700MHz, and the high-frequency band-pass assembly and the low-frequency assembly realize ultra-wide-band low-pass and high-pass dual-frequency signal efficient combination transmission through a combination output end.

The application discloses a kind of millimeter wave injection locking tripler, including two parts of harmonic generator and injection locking oscillator.Harmonic generator is used to generate harmonic signal, and injection locking oscillator is used to lock the harmonic generated by harmonic generator, and harmonic generator is connected with injection locking oscillator by transformer coupling.Compared with the structure of conventional frequency multiplier, the application still has a wide locking range when the input power is small, and has the advantages of ultra-wide bandwidth, low input sensitivity, low power consumption, high integration and the like.
