Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is entered Row clearly and completely describes, it is clear that described embodiment is only a part of embodiment of the present invention, Rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having Have and make the every other embodiment obtained under creative work premise, broadly fall into present invention protection Scope.

Term " first " in description and claims of this specification and above-mentioned accompanying drawing, " second ", " the 3rd " and " the 4th " etc. are for distinguishing different object rather than for describing particular order. Additionally, term " includes " and " having " and their any deformation, it is intended that cover non-exclusive Comprise.Such as contain series of steps or the process of unit, method, system, product or equipment It is not limited to step or the unit listed, but the most also includes step or the list do not listed Unit, or the most also include other step intrinsic for these processes, method, product or equipment or Unit.

In below describing, in order to illustrate rather than in order to limit, it is proposed that such as particular system structure, The detail of interface, technology etc, in order to thoroughly cut and understand the present invention.But, the technology of this area Personnel are it should be clear that can also realize the present invention in the other embodiments do not have these details. In other situation, omit the detailed description to well-known device, circuit and method, in order to avoid Unnecessary details hinders description of the invention.

It addition, the terms "and/or", a kind of incidence relation describing affiliated partner, Can there are three kinds of relations, such as, A and/or B in expression, can represent: individualism A, simultaneously There is A and B, individualism B these three situation.It addition, character "/" herein, typically represent The forward-backward correlation relation to liking a kind of "or".

In the subsystem of existing room, in order to take into full account the overall covering of room subsystem, BBU uses straight Receive and send one of them logic port signal to the mode of all of RRU physical port to send signal, Or, BBU uses and directly transmits identical logic port signal to two RRU physics of arbitrary neighborhood The mode of port sends signal.Wherein, two adjacent RRU refer in the most a certain plane Two RRU that distance is the shortest.

Such as, as in figure 2 it is shown, in two floors, every floor arranges the RRU that a single-shot list is received, And using power splitter to realize the distributed arrangement of domestic aerial, BBU is directly by logic port signal P0 The signal of the port being sent to RRU1 and RRU2, RRU1 and RRU2 is P0, and then, RRU1 will Signal P0 is sent to power splitter 1, and signal P0 employing merit divisional processing is obtained two-way power by power splitter 1 Equal signal P0, in like manner, signal P0 is sent to power splitter 2 by RRU2, and power splitter 2 is by signal P0 uses merit divisional processing to obtain the signal P0 that two-way power is equal.

In prior art, owing to using above-mentioned signal processing method to make adjacent two RRU physics end The signal of mouth is identical, and the signal of two physical ports is the same logic port signal that frequency is identical, Therefore, the signal that the antenna corresponding to physical port of two adjacent RRU is launched falls within same Logic port signal.If terminal is in the letter that the antenna corresponding to adjacent two physical port is launched During number region collectively covered, when even terminal is in signal overlapping coverage area, this terminal will connect Receiving the individual logic port signal that two-way frequency is identical, so, terminal can only parse a logical end Message number, and other logic port signals cannot be known, cause the waste of resource, further, since Two signals during signal covers crossover region in existing system are same logic port signal, therefore, Existing signal covers crossover region can effectively support two-way power diversity, but cannot support multithread multiplexing, Cause power system capacity relatively low.

Such as, as in figure 2 it is shown, there is signal between Stall and second floor to cover crossover region, it is in this letter Number terminal A covered in crossover region receives the signal P0 of antenna 1 and the signal P0 of antenna 2, sky The signal P0 of the line 1 and signal P0 of antenna 2 is same logic port signal, and terminal A is in demodulation During the signal received, a signal P0 can only be identified, and also another road signal cannot be known P0 exists, and so, result in the waste of resource.

And following example of the present invention do not retransmit identical logical end to two adjacent physical ports Message number, but be weighted multiple logic port signals processing, then process is obtained signal one Being launched by the antenna corresponding to physical port of one correspondence, wherein, the signal of each physical port is By at least two logic port signal syntheses, and the signal of two adjacent physical ports is uncorrelated , so, signal covers crossover region just can support multithread multiplexing, improves power system capacity, and is positioned at The terminal that signal covers in crossover region also is able to parse each logic port signal accurately, without Cause the wasting of resources.

The various technology that the present invention describes are applicable to room subsystem, apply also for other distributed networkings.
