Embodiment Construction
[0030] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0031] A schematic diagram of an embodiment of the RRU for cross-band carrier aggregation of the present invention is as follows figure 1 shown. Wherein, the first port 101 is used to connect the input port or the input and output port of the additional RRU; the input side of the combiner 102 is respectively connected to the first port and the transceiver of the RRU for cross-band carrier aggregation, and the output side is connected to the second port; The second port 103 is a port for connecting the RRU and the antenna for cross-band carrier aggregation. The additional RRU and the RRU used for cross-band carrier aggregation work in different frequency bands.
[0032] Such an RRU can internally aggregate the signal of the additional RRU and its own signal, so that the common antenna can be realized without an extern...
