In existing room subsystem, in order to fully consider the whole covering of room subsystem, BBU is using directly transmitting wherein one
A logic port signal sends signal to the mode of all RRU physical ports, alternatively, BBU is identical using directly transmitting
The mode of two RRU physical ports of logic port signal to arbitrary neighborhood sends signal.Wherein, two adjacent RRU are
Refer to shortest two RRU of distance in a certain plane in space.
For example, as shown in Fig. 2, every floor arranges the RRU that a single-shot list is received, and using function point in two floors
Device realizes the distributed arrangement of domestic aerial, and BBU directly sends RRU1 and RRU2, RRU1 and RRU2 for logic port signal P0
The signal of port be P0, then, signal P0 is sent to power splitter 1 by RRU1, and power splitter 1 is by signal P0 using function point processing
The equal signal P0 of two-way power is obtained, similarly, signal P0 is sent to power splitter 2 by RRU2, and signal P0 is used function by power splitter 2
Processing is divided to obtain the equal signal P0 of two-way power.
In the prior art, due to using above-mentioned signal processing method to make the signal phase of two adjacent RRU physical ports
Together, the signal of two physical ports is the identical same logic port signal of frequency, therefore, the physics of two adjacent RRU
The signal of the transmitting of antenna corresponding to port also belongs to the same logic port signal.If terminal is in two adjacent physics ends
It, should when even terminal is in signal overlapping coverage area when the region that the signal that the antenna corresponding to mouthful is launched is collectively covered
Terminal will receive the identical a logic port signal of two-way frequency, in this way, terminal can only parse a logical end message
Number, and can not know other logic port signals, the waste of resource is caused, in addition, due to signal covering friendship in existing system
Two signals in folded area are the same logic port signal, and therefore, existing signal covering crossover region can effectively support two-way
Power diversity, but multithread can not be supported to be multiplexed, cause power system capacity lower.
For example, as shown in Fig. 2, there are signals to cover crossover region between Stall and second floor, in signal covering crossover region
In terminal A receive the signal P0 of antenna 1 and the signal P0 of antenna 2, the signal P0 of antenna 1 and the signal P0 of antenna 2 are same
One logic port signal, terminal A can only identify a signal P0 in the signal that demodulation receives, and can not know also
With the presence of another way signal P0, in this way, resulting in the waste of resource.
And following embodiment of the present invention does not retransmit identical logic port signal to two adjacent physical ports, but
Processing is weighted to multiple logic port signals, processing is then obtained into signal and is passed through corresponding to physical port correspondingly
Antenna transmitting, wherein the signal of each physical port is synthesized by least two logic port signals, and adjacent two
The signal of physical port is incoherent, in this way, signal covering crossover region can support multithread to be multiplexed, raising power system capacity,
And the terminal being located in signal covering crossover region also can accurately parse each logic port signal, without will cause resource
Waste.
The various technologies that the present invention describes are suitable for room subsystem, apply also for other distributed networkings.
