Abstract

The embodiment of the invention provides TDD communication equipment, a TDD communication system and a power adjustment method, and the TDD communication equipment comprises a receiving and transmitting circuit which is used for transmitting a first signal to a TDD repeater and receiving a second signal from the TDD repeater; and the receiving and transmitting circuit is directly connected with the TDD repeater on a downlink, or a first attenuation module is arranged on the downlink between the receiving and transmitting circuit and the TDD repeater. In the embodiment of the invention, the TDDcommunication equipment is directly connected with the TDD repeater, and the TDD communication equipment adjusts the downlink power and removes a downlink passive attenuation network, so that the energy waste is avoided, and the cost of the attenuation network is saved; or the first attenuation module is arranged on the downlink of the TDD communication equipment and the TDD repeater, the downlink power is adjusted by the TDD communication equipment and the TDD repeater together, and by reducing the transmitting power of the TDD communication equipment, the energy waste is reduced, the attenuation network is simplified, the cost is saved, and the construction complexity is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a TDD communication device, a TDD communication system, and a power adjustment method. Background technique [0002] In the current time division duplex (Time Division Duplexing, TDD) active indoor distribution system, the downlink input power of active indoor distribution equipment such as digital optical fiber repeater and optical fiber distribution system is limited to a certain extent, and generally it is much lower. Due to the downlink transmission power of the communication device (also called the master device), it is usually necessary to install a passive attenuation network between the master device and the active time-division device. The most typical attenuation network is composed of a coupler or an attenuator. Its specific equipment connection such as Figure 1a and Figure 1b shown. [0003] There are following disadvantages in ...
