Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the present invention, the embodiments and features of the embodiments are described without conflict.

An increased capacity leaky cable covering system, as shown in fig. 1, comprising:

a baseband signal processing unit 1 for generating a downlink signal and receiving an uplink signal;

one or more near-end switching units 2, respectively connected to the baseband signal unit 1, for transmitting downlink signals and uplink signals;

a plurality of far-end radio frequency processing units 3 connected to the near-end switching unit 2 for processing downlink signals and uplink signals;

and the plurality of wide-angle leakage cables 4 are connected with the far-end radio frequency processing unit 3 and are used for outputting downlink signals and receiving uplink signals.

And each antenna is connected with the wide-angle leakage cable 4 through a flexible jumper 6 and is used for outputting downlink signals and receiving uplink signals.

Specifically, in the prior art, a radio remote unit is often used as a signal source and single-cable deployment is performed, or an antenna is used as a point source to transmit/receive radio frequency signals, which finally results in limited network capacity of a communication system, uneven coverage, incapability of meeting the requirements of communication services, and even incapability of supporting MIMO multi-channel transmission of a 5G network. Therefore, aiming at the defects of the prior art, the invention discloses a leakage cable covering system for constructing the increased capacity, which comprises a baseband signal processing unit 1, a near-end switching unit 2, a far-end radio frequency processing unit 3, a wide-angle leakage cable 4 and an antenna so as to enlarge the propagation range and increase the network capacity.

In this embodiment, when a 5G networking architecture is implemented, a CU/DU (Central Unit/Distributed Unit) is selected as the baseband signal processing Unit 1, and an NG interface and a core network are connected to the upper side, and a baseband signal processing function is implemented to the lower side. The data aggregation unit and the like are selected as a near-end exchange unit 2, a pRRU (pico Remote radio unit) is selected as a far-end radio frequency processing unit 3 to be connected with a wide-angle leakage cable 4, the wide-angle leakage cable 4 is connected with an antenna through a soft jumper 6, and the antenna can be selected from an omnidirectional antenna, a directional antenna, a single-polarization antenna and a multi-polarization antenna.

Further, in a preferred embodiment of the present invention, the antenna further includes a 4G antenna 5a and a 5G antenna 5 b.

Therefore, as shown in fig. 1, when the baseband signal processing unit 1 generates a downlink signal, the baseband signal processing unit 1 outputs the downlink signal to the far-end rf processing unit 3 through the near-end switching unit 2, and the far-end rf processing unit 3 receives and processes the downlink signal, and outputs the processed downlink signal through the wide-angle leakage cable 4 and the antenna. When the wide-angle leakage cable 4 and the antenna receive the uplink signal, the wide-angle leakage cable 4 and the antenna output the uplink signal to the far-end rf processing unit 3, the far-end rf processing unit 3 receives and processes the uplink signal, and outputs the processed uplink signal to the baseband signal processing unit 1 through the near-end switching unit 2, thereby finally forming the MIMO multi-channel leakage cable covering system which can reach 4T4R of four channels at most as shown in fig. 1.

Further, as shown in fig. 2, the wide-angle leakage cable 4 is composed of an inner conductor 41, an insulating part 42, an outer slot hole 43, a conductor 44, and a sheath 45, and the wide-angle leakage cable 4 is laid along a line according to an indoor environment and is deployed by a hanging rib or a mounting jig to realize a main lobe radiation direction vertically downward, thereby completing signal coverage. In addition, considering practical environment and installation standard, as long as the deviation angle between the main lobe radiation direction and the vertical direction does not exceed +/-5 degrees, a better covering effect can be realized.

The invention is suitable for signal coverage of different scene types, different from the situation that a signal coverage blind area is finally generated by using a remote radio frequency processing unit with a built-in antenna in the prior art, and the invention can avoid the signal blind area by arranging the remote radio frequency processing unit 3, the wide-angle leakage cable 4 and the antenna, thereby playing the role of blind area compensation. In addition, the far-end radio frequency processing unit 3 is externally connected with the antenna, so that the construction difficulty of workers can be reduced, and the economic cost of feeder investment is reduced.

and single-polarized antennas, wherein each single-polarized antenna is connected to the tail end of the wide-angle leakage cable 4 through a flexible jumper 6.

In one embodiment of the present invention, an antenna includes:

and each dual-polarized antenna is connected to the tail end of the wide-angle leakage cable 4 through two soft jumper wires 6.

According to the embodiment, the coverage system provided by the application adopts the far-end radio frequency processing unit 3 as the information source of the system, compared with the radio frequency remote unit scheme adopted in the prior art, the implementation difficulty is high, and only one of integral expansion and non-expansion can be selected during MIMO expansion, the system can effectively increase the system capacity, so that flexible expansion of a small area is facilitated, more users are accommodated, the access success rate and the accuracy of network optimization are improved, and the economic cost of network optimization is reduced.

In addition, this application still adopts wide angle to leak cable 4 and connects distal end radio frequency processing unit 3, has better blind effect of benefit in current 4G/5G indoor coverage system, changes to satisfy building owner and conceals construction and fitment style uniformity requirement.

The problem that in the prior art, the radio remote unit is adopted as the information source to be deployed, and the cable route is too long, and the isolation between 4 cables and the route cannot realize multi-channel coverage can be solved, and the network capacity of the embodiment is 1 to 3 times higher than that of the prior art.

Further, a far-end radio frequency processing unit 3 is connected with a wide-angle leakage cable 4 to increase a leakage cable application scene, compared with the prior art that a radio frequency remote unit is adopted as an information source for deployment, the leakage cable application scene can be obtained through the following calculation:

Therefore, compared with the prior art, the system greatly improves the network capacity by 1 to 3 times.

Furthermore, according to indoor service and scene requirements, the selection and deployment of double-cable and four-cable medium-high capacity indoor coverage schemes can be flexibly performed. And according to the later service development situation, the local far-end radio frequency processing unit 3 can be added and the cells can be split, so that the capacity expansion can be carried out, and the capacity adjustment is more convenient.
