摘要： Certain features relate to systems and methods for jointly optimizing a radio access network (RAN) and distributed antenna system (DAS). A joint RAN-DAS self-optimizing network (SON) entity can determine target parameters based on parameters specific to the DAS and parameters specific to the RAN. The joint RAN-DAS-SON entity can optimize the RAN and DAS using the target parameters. Jointly optimizing the RAN and the DAS can improve the capacity characteristics, coverage characteristics, or the performance characteristics of the RAN and DAS. In some aspects, the joint RAN-DAS-SON entity can optimize the RAN and DAS by re-allocating power levels of downlink signals transmitted by remote units of the DAS to compensate for underutilized carrier signals in situations of low traffic load.

摘要： The present invention provides a channel detection method applied when an LTE system works in an unlicensed frequency band, a terminal and a base station. The channel detection method applied when an LTE system works in an unlicensed frequency band comprises determining a current sub-frame when a data traffic arrives, and setting a channel detection time in the current sub-frame and/or in a next adjacent sub-frame to perform channel state detection; and performing data traffic transmission when it is detected that the channel is in an idle state. By means of the technical solution of the present invention, on the premise that the normal working of the LTE system in the unlicensed frequency band is guaranteed, the time delay of data traffic transmission due to channel state detection at a fixed detection period can be effectively reduced, thereby improving data traffic transmission efficiency and at the same time achieving harmonious coexistence of the LTE system and other systems in the unlicensed frequency band.

摘要： A power detector for detecting an output power of a power amplifier is provided. The power amplifier is used to transmit signal power to the antenna. The power detector includes a phase shifter, a multiplier and a calibration unit. The phase shifter sequentially applies a plurality of candidate phase calibration amounts to the output voltage of the power amplifier to generate a plurality of adjusted signals with different phases in a calibration mode. The multiplier sequentially mixes the replica current and each of the plurality of adjusted signals, to generate a plurality of analog signals with different phases. The calibration circuit determines a target phase calibration amount of the phase shifter from the candidate phase calibration amounts according to the plurality of analog signals.

摘要： A method for calibrating a transmitter includes operating the transmitter using a first transmitter setting; obtaining, via an external reference measuring device, a transmit power reference value indicative of a first transmit power of the transmitter corresponding to the first transmitter setting, and obtaining, using an internal measuring device of the transmitter or of a receiver associated with the transmitter, a first uncalibrated transmit power measurement value corresponding to the first transmit power. The method further includes calibrating the internal measuring device using the transmit power reference value and the first uncalibrated transmit power measurement value to provide a calibrated internal measuring device, operating the transmitter using a second transmitter setting, and obtaining, using the calibrated internal measuring device, a second transmit power measurement value indicative of a second transmit power corresponding to the second transmitter setting. Lastly, the method includes obtaining self-calibration data based on the second transmitter setting and the second transmit power measurement value, and storing the self-calibration data in a calibration data structure.

摘要： A mobile phone terminal includes a transmitting side speech signal path switch and receiving side speech signal path switch, and a general purpose USB port. The signal path switches are interposed between a speech coder/decoder and an A/D converter and D/A converter to enable a terminal acoustic evaluation signal to be input and output through a path different from that in a normal operation mode of the mobile phone terminal. The general purpose USB port is used for connecting the signal path switches with an external terminal unit so that the control signals of the signal path switches and a terminal acoustic test signal are transferred across these signal path switches and the general purpose USB port. The mobile phone terminal can mount the external connection port for the acoustic evaluation test more efficiently.

摘要： A reception amplifier failure detecting device includes an antenna sharing unit, a reception amplifier, a receiver, an electric field detecting section, a transmitter, a power control section, and a failure detecting section. The antenna sharing unit demultiplexes a transmission signal from a transmission system to an antenna and a reception signal from the antenna to a reception system. The reception amplifier amplifies the reception signal. The receiver receives an output signal from the reception amplifier. The electric field detecting section detects the electric field strength of a signal received by the receiver. The transmitter outputs a transmission signal to the antenna via the antenna sharing unit. The power control section controls the transmission power of the transmitter on the basis of a standard transmission value, and outputs transmission power information. The failure detecting section performs failure determination by comparing the electric field strength information with a failure detection reference value set on the basis of a standard attenuation value, a standard amplification value of the reception amplification means, and the transmission power information of the transmission means. A reception amplifier failure detecting method is also disclosed.

摘要： Methods and systems for automated testing of extremely-high frequency devices are disclosed. A device under test (DUT) is set in a simultaneous transmit and receive mode. The DUT receives a lower frequency radio frequency (RF) signal from a test unit and up-converts the lower frequency RF signal to a higher frequency RF signal. The DUT transmits the higher frequency RF signal using a first antenna, and receives the higher frequency RF signal using a second antenna. The DUT down-converts the received higher frequency RF signal to a received test RF signal and provides the received test RF signal to the test unit for comparing measurements derived from the received test signal to a design specification for the DUT.
