Example Embodiment

[0030] Example 1

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

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

[0054] Embodiment 2

[0055] image 3 Shown is a schematic diagram of coverage in a macro station scenario of a high-power coverage device of a TDD mobile communication system, and figure 2 In contrast, this embodiment adds a signal receiving apparatus for signal diversity reception on the basis of Embodiment 1 (and the signal receiving apparatus in this embodiment specifically adopts an antenna feeder system), and at the same time adds an uplink filter, a RF switch and an uplink low noise amplifier, wherein, the newly added uplink low noise amplifier is directly connected with the TDD base station, and the newly added RF switch is connected with the synchronization unit. Both radio frequency switches are under the command of the synchronization unit: when the TDD base station is in the downlink transmitting state, the two radio frequency switches are in the off state, and when the TDD base station is in the uplink receiving state, the two radio frequency switches are in the...

[0057] Embodiment 3

[0058] like 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 a power amplifier, while traditional TDD equipment is combined with the FDD base station after uplink and downlink. The maximum withstand power of the circulator cannot achieve high-power coverage, so it cannot achieve synchronous coverage with other systems. For this reason, in this embodiment, after the TDD uplink and downlink signals are separated by a circulator, the downlink is power amplified by a high-power amplifier, and then combined with the downlink input of the FDD base station into the downlink POI, and connected to the downlink transmission antenna feeder system Complete downlink coverage; uplink i...

The downlink high power amplifier is connected with a signal emission device, and the uplink low noise amplifier is connected with a signal receiving device. 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...
