Embodiment 1

[0031] see figure 2 As shown, this embodiment provides a high-power coverage device for a TDD mobile communication system, including: a donor-side circulator, a downlink high-power amplifier, and an uplink low-noise amplifier; the downlink high-power amplifier is connected to a signal transmitting device, and the The uplink low-noise amplifier is connected to the signal receiving device, the uplink low-noise amplifier and the downlink high-power amplifier are respectively connected to the donor-end circulator, and the donor-end circulator is connected to the TDD base station;

[0032] The donor-side circulator is used to separate the TDD uplink and downlink signals, and send the separated downlink signals to the downlink high-power amplifier (downlink); and combine the amplified uplink signals with the downlink signals , and send the combined signal to the TDD base station (uplink);

[0033] The downlink high-power amplifier is used to perform power amplification processing ...

Embodiment 2

[0055] image 3 Shown is a schematic diagram of the coverage of a TDD mobile communication system high-power coverage device in a macro station scenario, and figure 2 In contrast, this embodiment adds a signal receiving device for signal diversity reception on the basis of the first embodiment (and the signal receiving device in this embodiment specifically adopts an antenna feeder system), and at the same time adds an uplink filter, an A radio frequency switch and an uplink low noise amplifier, wherein the newly added uplink low noise amplifier is directly connected to the TDD base station, and the newly added radio frequency switch is connected to the synchronization unit. The two RF switches are under the command of the synchronization unit: when the TDD base station is in the downlink transmitting state, the two RF switches are in the off state, and when the TDD base station is in the uplink receiving state, the two RF switches are in the connected state, which avoids Wh...

Embodiment 3

[0058] Such as Figure 4 Shown is a schematic diagram of combined synchronous coverage of a high-power coverage device of a TDD mobile communication system and a high-power coverage device of an FDD mobile communication system. When multiple systems are combined for high-power coverage, the FDD system can easily complete high-power coverage through the power amplifier, while the traditional TDD equipment is combined with the uplink and downlink of the FDD base station for coverage, so it is also limited The maximum tolerable power of the circulator cannot complete high-power coverage, and it cannot achieve synchronous coverage with other systems. Therefore, in this embodiment, after the TDD uplink and downlink signals are separated by a circulator, the downlink is amplified by a high-power amplifier and combined with the downlink input of the FDD base station into the downlink POI, and connected to the downlink transmitting antenna feeder system The downlink coverage is compl...

The uplink low noise amplifier and the downlink high power amplifier are respectively connected with the donor end circulator which is connected with a TDD base station. The high-power covering method and the covering device of the TDD mobile communication system promote covering effect and reduce real estate coordination difficulty, and the covering device has good market application prospect.

Description

technical field [0001] The invention relates to a TDD mobile communication system, in particular to a high-power coverage method for a TDD mobile communication system and a high-power coverage device for a TDD mobile communication system. Background technique [0002] In some scenarios, a high-power amplification device is sometimes used to amplify the base station signal for coverage alone or after being combined by a combiner for coverage. However, in the TDD (Time Division Duplexing) system, since the uplink and downlink have the same frequency, it is necessary to use a circulator to combine the downlink output of the high-power amplifier device, such as figure 1 As shown, in the downlink: the downlink filter performs downlink filtering on the signal from the TDD base station, and the donor-side circulator separates the filtered signal from uplink to uplink, and then performs power amplification processing through the downlink high-power amplifier, and retransmits The en...
