Abstract:
A co-time, co-frequency full-duplex terminal includes a radio frequency transceiver, a power divider, a local transmitting antenna, a controllable adaptive module, and a signal mixer. The radio frequency transceiver transmits a radio frequency signal. The power divider divides the radio frequency signal into radio frequency signals in a first path and a second path. The local transmitting antenna transmits the radio frequency signal in the first path. The controllable adaptive module controls the radio frequency signal in the second path to have an amplitude equal to an amplitude of a self-interference signal and have a phase opposite to a phase of the self-interference signal. The signal mixer mixes the radio frequency signal, after being controlled by the controllable adaptive module, with a base station signal and the self-interference signal.
Abstract:
The present invention discloses a wireless communication data transmission method, receiving a data sent from a base station to a mobile terminal with a downlink frequency channel by using full-duplex technology; emitting a data emitted from the mobile terminal to the base station, and receiving the data sent from the base station to the mobile terminal by using time division multiplexing technology through an uplink frequency channel. The uplink frequency channel, which is originally only used for emitting a base station uplink data, is used for receiving a data originally only received by the downlink frequency channel.

Abstract:
A method and a mobile terminal for displaying a user guide are provided, the method comprising: displaying a user guide icon on top of the screen of the mobile terminal; when detecting that the user guide icon is clicked, displaying a description page of the user guide on the screen of the mobile terminal. By the above method, the present disclosure can remedy the deficiencies present in the prior art that paper manuals are troublesome to carry with, not environmentally friendly, expensive and not conducive to browse and use, and can meanwhile, allow the user to open the user guide at any time during the process of operating the mobile terminal, thus greatly facilitating the operation for the user.
Abstract:
A fast charging terminal is provided, which includes a battery, a USB interface, a switch module, a supply voltage detecting unit, a central processor, and a charging management unit. After the USB interface is connected to an intelligent charger, the switch module is switched on when the supply voltage outputted by the USB interface is within a safe supply voltage range such that the charging management unit converts the supply voltage and the supply current. The charging management unit decreases the supply voltage and increases the supply current to charge the battery.
Abstract:
A mobile terminal and a system with a multichannel transceiver are provided. The mobile terminal includes a central processing unit and a multichannel transceiver. The central processing unit outputs first and second transmitted signals to a first transmitter module and a second transmitter module. The first and second transmitted signals are filtered, frequency-converted, amplified, and transmitted to corresponding transmitting channels. First and second received signals received by a plurality of receiving channels are amplified and then transmitted to a first receiver module and a second receiver module, respectively, and the first and second received signals are frequency-converted, filtered, and output to the central processing unit.

In the present disclosure, the mobile terminal is bonded with a SIM card, the SIM card is multifunctional, and a single SIM card corresponds to a plurality of terminals.
Abstract:
A wireless terminal and data receiving and transmitting methods thereof are described. When the wireless terminal receives data, an antenna is used for receiving receipt signals from an uplink band and a downlink band, allowing mixed signals to enter a duplexer. The duplexer separates receipt signals from the uplink band and downlink band, and passes the receipt signal from the downlink band through a downlink band receiving end and passes the receipt signal from the uplink band through a shift switch to enter a central processing unit for aggregation together.
Abstract:
An offline communication method includes steps of: receiving, by a first TDD (Time Division Duplexing) terminal, an instruction for setting the first TDD terminal as a D2D (Device-to-Device) terminal device; interchanging, by the first TDD terminal, upstream time slots and downstream time slots thereof, and setting the first TDD terminal to be in a mode of conforming a D2D communication environment in response to said instruction; and searching, in a mode that the upstream time slots and the downstream time slots are interchanged, for a second TDD terminal which is adjacent to the first TDD terminal and is not set as a D2D mode, and establishing a connection therebetween after the second TDD terminal is searched out. By this way, communication between those offline intelligent mobile terminals within a short distance can be carried out.
