Embodiment Construction
[0052] The present invention will be described below in conjunction with the accompanying drawings and embodiments.
[0053] The uplink and downlink time slot synchronization scheme proposed in the embodiment of the present invention is applicable to but not limited to the distributed pico base station cost reduction scheme, such as figure 1 shown. The distributed pico base station includes: a baseband unit, a switching unit and a radio frequency unit. In order to reduce the total cost of the distributed pico base station network, the radio frequency unit is implemented by connecting multiple amplification units externally through a power divider to expand its coverage. The external amplifying unit works in the TDD mode, and its uplink and downlink time slot switching switches need a control signal (that is, the above-mentioned uplink and downlink time slot synchronization signal).
[0054] An embodiment of the present invention provides an uplink and downlink time slot sync...
