The invention provides a simultaneous and same-frequency full-duplex system and a mobile terminal. Wherein, the simultaneous and same-frequency full-duplex system includes: a baseband processing circuit, a signal processing circuit at a transmitting end, a signal processing circuit at a receiving end, and a signal transceiving circuit. Wherein, the first end of the baseband processing circuit is electrically connected to the first end of the signal processing circuit at the transmitting end; the second end of the signal processing circuit at the transmitting end is electrically connected to the first end of the signal transceiving circuit; the second end of the baseband processing circuit is electrically connected to the first end of the signal processing circuit at the transmitting end The first end of the signal processing circuit at the receiving end is electrically connected; the second end of the signal processing circuit at the receiving end is electrically connected to the second end of the signal transceiving circuit; wherein, the signal transceiving circuit is used to simultaneously transmit uplink signals and receive downlink signals, and to Uplink and downlink signals are isolated. In the above technical solution, one signal transceiver circuit is used to transmit uplink signals and receive downlink signals, isolate uplink signals and downlink signals, perform self-interference suppression, and reduce link complexity.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a simultaneous and same-frequency full-duplex system and a mobile terminal. Background technique [0002] The 5G mobile communication system needs to support higher uplink and downlink rates, so it needs larger bandwidth and higher spectral efficiency support, while the current 4G LTE communication system only supports TDD Time Division Duplexing (TDD for short) or Frequency Division Duplexing (FDD for short) mode is inflexible in configuration and low in spectrum utilization. Therefore, simultaneous same-frequency full-duplex technology has been proposed as one of the key technologies of 5G, and the effect to be achieved is : Uplink and downlink communicate on the same frequency at the same time. In the simultaneous and same-frequency full-duplex system in the prior art, in order to achieve self-interference suppression (that is, the interference of the transmitted signa...
