Embodiment 1

[0035] Such as figure 1As shown, when the signal relay system for 5G communication of the present invention adopts frequency division duplex technology, the operating frequency of the downlink signal enhancement subsystem 10 is different from that of the uplink signal enhancement subsystem 20 . At this time, the two subsystems can work at the same time, that is, the base station can also receive signals transmitted by the wireless terminal while sending signals to the wireless terminal.

[0036] At a certain moment, the first receiving antenna 11 in the downlink signal enhancement subsystem 10 receives the base station signal with frequency f1, after being amplified and filtered by the first low noise amplification module 12, it passes through the first transmitting antenna with omnidirectional radiation characteristics 13 Spread toward the interior of the building. At the same time, the second receiving antenna 21 in the uplink signal enhancement subsystem 20 receives the wi...

Embodiment 2

[0038] Such as figure 2 As shown, when the signal relay system for 5G communication of the present invention adopts time-division duplex technology, the operating frequency of the downlink signal enhancement subsystem 10 is the same as that of the uplink signal enhancement subsystem 20. At this time, the two subsystems are respectively Work.

[0039] At time t1, the first receiving antenna 11 in the downlink signal enhancement subsystem 10 receives the base station signal with frequency f, after being amplified and filtered by the first low noise amplification module 12, it passes through the first transmitting antenna 13 with omnidirectional radiation characteristics Spread towards the interior of the building. At time t2, the second receiving antenna 21 in the uplink signal enhancement subsystem 20 receives the wireless terminal signal with frequency f, after being amplified and filtered by the second low noise amplification module 22, it passes through the second transmit...

Embodiment 3

[0041] Such as image 3 As shown, when the signal relay system for 5G communication of the present invention adopts simultaneous and same-frequency full-duplex technology, the operating frequency of the downlink signal enhancement subsystem 10 is the same as that of the uplink signal enhancement subsystem 20, and the two sets of The system can work at the same time, which requires high isolation performance between the two subsystems.

[0042] At a certain moment, the first receiving antenna 11 in the downlink signal enhancement subsystem 10 receives the base station signal with frequency f, after being amplified and filtered by the first low-noise amplification module 12, it passes through the first receiving antenna 11 with high isolation and omnidirectional radiation characteristics. A transmitting antenna 13 propagates in the direction of the interior of the building. At the same time, the second receiving antenna 21 in the uplink signal enhancement system 20 can receive ...

According to the system, a 5G signal sent by a base station can be effectively amplified and transmitted to an indoor wireless terminal, moreover, a signal of the indoor wireless terminal can be amplified and uploaded to the base station, the reliability of a wireless communication system is improved, the problem that a signal shade and a blind area exist in a building is solved, and various indoor wireless terminal devices can carry out communication normally.

Description

technical field [0001] The present invention relates to the technical field of the fifth generation wireless communication, in particular to a signal relay system for 5G communication. Background technique [0002] With the rapid development of communication technology, there will be more and more wireless terminal users, which will inevitably lead to an increase in network demand, resulting in a shortage of spectrum resources. According to the development trend at home and abroad, the millimeter wave frequency band will become a main frequency band of the 5G communication system. However, in the millimeter wave frequency band, the signal power attenuates very quickly with the propagation distance and obstacles, and the signal often becomes very weak after passing through walls or glass, and may not even be received by wireless terminals. [0003] Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0004] T...
