US 12,726,326 B2 · Time division duplexing (TDD) synchronized compensation

Abstract

Disclosed are exemplary methods and devices (e.g., circuits, compensators, low-gain signal boosters, repeaters, signal amplifier devices, etc.) for providing time division duplexing synchronized compensation between a terminal device (e.g., mobile phone, user equipment within a vehicle, a coupling antenna on a wireless charger, etc.) and an antenna (e.g., a vehicle roof antenna, etc.) or antenna connection, etc. In an exemplary embodiment, a circuit includes at least one detector, at least one control unit, at least one uplink path including at least one transmission amplifier, and at least one downlink path including at least one reception amplifier. The uplink and downlink paths are configured to be operable for respectively amplifying uplink and downlink signals having a same frequency according to time division duplexing. The control unit is configured to be operable for activating the uplink path and deactivating the downlink path before an uplink signal is transmitted by a terminal device.
