摘要： An eNodeB in a TDD system (100), comprising first and second transmitters (408-411 ), a first receiver (302; 402-405), a control unit (306, 416), and means (305, 415) for diverting part of a transmitted signal from the first and second transmitters (408-411 ) to the first receiver (302; 402-405). The diverting means (305, 415) are connected to the transmitter part via a switch function (308, 418) and the transceiver also comprises a delay component (304, 404. The control unit (306, 416) activates the switch (308, 418) when the output power of the transmitted signals falls below a threshold, and the delay component (304, 404) delays so that the diverted signals are received by the receiver part (303; 402-405) at a predefined point in time. The transceiver (300) comprises a comparison unit (307, 417) for comparing the diverted signals from the first and second transmitters after reception through the first receiver.

摘要： Disclosed is a method for providing ability of tuning resonance frequency in different applications. The method according to the invention at least comprises the step of adding ferroelectric disks in the resonators. Here, the ferroelectric disks have the relative dielectric constants varying according to change of ambient environment. In the invention, since the resonance frequency can vary according to the ambient environment, the tuning range of filters and duplexers/multiplexers having the resonators with ferroelectric disks is large. In addition, the resonance frequency can be changed in high frequency environment according to the invention. So, the invention can be used to improve the size and cost of the filters and duplexers/multiplexers in different applications, especially in low noise environment.

摘要： Method and radio node(500) for controlling a change of communication mode between transmit mode and receive mode according to a Time Division Duplex, TDD, scheme. The radio node has at least two parallel branches (504, 06) for transmission and reception of radio signals, wherein the branches currently operate in a first communication mode. The radio node obtains one or more indication signals (S1A, S1B) generated by one or more of the branches to indicate that the first mode has been turned off. When it is determined that the first communication mode has not been turned off in a faulty branch, e.g. by not receiving an indication signal in time from that branch,the first mode is disabled in the faulty branch, and/or the faulty branch is reported to a supervision centre (510). Thereby, it can be discovered when one of the branches is misaligned or otherwise faulty and suitable actions can be taken for repairing or replacing the faulty branch.

摘要： Method and apparatus for controlling performance in a TDD radio node (600) having multiple parallel branches (604, 606) and antennas (604a, 606a) for radio transmission of signals propagating through a transmit chain in each of the branches before emission from the antennas. A signal generator (602a) generates a signal that propagates through each branch, and tapping means (608) taps the signal from each of the branches after the transmit chain. A control unit (610) then determines a timing of the tapped signal from each of the branches, and monitors timing alignment of the branches based on the determined timing of tapped signals. If it is discovered that there is a timing misalignment between the branches which exceeds a preset acceptable limit, a transmission delay can be adjusted for at least one of the branches to reduce the misalignment.
