摘要： Techniques for compensating for the time misalignment of receive-transmit switching in a multi- antenna radio network node are disclosed. An example method begins with the detection (1020) of signal transmission timing for each of two or more antennas associated with the radio network node, for at least a first transmission period. Next, the radio network node determines (1030) that transmit timing for at least one of the antennas is misaligned by at least a first threshold time interval, based on the detected signal transmission timings. The example method continues with the adjustment (1040) of transmit timing for at least one of the antennas for one or more subsequent transmission periods, responsive to determining that the transmission timing for at least one of the antennas is misaligned.

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.

摘要： The present invention relates to radio base stations including a standardized interface CPRI between a Radio Equipment (RE) and a Radio Equipment Controller (REC). The present invention also relates to a method. The problem addressed is how to convey calibration information from the RE to the REC, when the capacity is occupied by radio IQ samples. The solution is to suppress the IQ samples to get capacity for the calibration information. Various embodiments of the invention focus on reducing the negative impact the suppression of IQ data may have on detecting the signals received.

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.
