Abstract

The application provides a method and device for transmitting and receiving calibration data of a TD-SCDMA (time division-synchronization code division multiple access) base station, and the method and the device are used for solving the problems that width phase consistency alarm is generated and a calibration effect is influenced during calibration in the prior art. The method for transmitting the calibration data of the TD-SCDMA base station comprises the following steps of: switching on a calibration switch when a downlink pilot frequency time slot is finished; controlling a transmission time slot through a register, and calibrating and transmitting calibration data of an antenna in the transmission timeslot reading register; and switching off the calibration switch when an uplink pilot frequency timeslot is finished. The method for receiving the calibration data of the TD-SCDMA base station comprises the following steps of: switching on the calibration switch when the downlink pilot frequency timeslot is finished; controlling a receiving timeslot through a register according to a transmission timeslot during data transmission, and storing calibration data received by a work antenna in the receiving timeslot into a memory; and closing the calibration switch when the uplink pilot frequency timeslot is closed. According to the application, the transmission timeslot and receiving timeslot of the calibration data can be regulated, remote interface is reduced, the anti-jamming capability during calibration can be enhanced, and the calibration effect is better.

Description

technical field [0001] The present application relates to mobile communication technology, in particular to a method for sending and receiving data calibrated by a TD-SCDMA base station, and a device for sending and receiving data calibrated by a TD-SCDMA base station. Background technique [0002] refer to figure 1 , which shows the structural diagram of the TD-SCDMA base station described in this application. [0003] TD-SCDMA (TimeDivision-SynchronousCodeDivisionMultipleAccess, Time Division Synchronous Code Division Multiple Access) base station mainly includes BBU (BaseBandUnit) and RRU (RemoteRFUnit). [0004] The work of the TD-SCDMA base station system is divided into uplink and downlink time slots. Among them, in the downlink direction, the RRU receives the control signal and baseband data signal from the BBU through the optical fiber, analyzes the data according to the protocol, performs up-conversion processing on the downlink data, and finally transmits it from...
