Embodiment Construction

[0085] like figure 1 As shown, the indoor distribution system, referred to as the room sub-system, mainly includes a near-sub system 1 and a plurality of remote sub-systems 2, wherein, the near-sub system 1 (also called the master node) receives the base station signal, and sends the base station signal to the remote sub-system. System 2 (also called the slave node), the remote subsystem 2 processes the received base station signal, and sends it to the air interface through the RF power division feeder system (such as a passive RF power division feeder system) to complete the base station signal in the indoor environment. cover.

[0086] further as figure 1 As shown in the figure, control units are set in the near-terminal system 1 and the far-end subsystem 2 respectively. For the sake of distinction, they are hereinafter referred to as the near-end control unit A1 and the far-end control unit A2, respectively. For the near-terminal system 1 and the far-end subsystem 2 Corre...

Abstract

Near-end and far-end control combining units, near-end and far-end subsystems, and room division systems, wherein the near-end control combining units include: a near-end first signal path, and the near-end first signal path is a single channel The multi-channel near-end second signal path is suitable for frequency-shifting the frequencies of the near-end second signals output by the multi-channel second signal source channels to different frequency points respectively to form multi-channel near-end third signals with different frequency points ; the first communication monitoring module, based on the signal parameter information of the near-end first signal and the near-end second signal and the far-end monitoring parameter information, controls the on-off of the multi-channel near-end second signal path, and The signal parameter information of the first signal and the second signal obtained by transmitting and measuring the near-end fourth signal is taken as the near-end signal parameter information; the combiner is suitable for the near-end first signal and the multi-channel near-end third signal Combined with the near-end fourth signal to form a near-end fifth signal, and transmit the near-end fifth signal to the single-channel cable.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a near-end and far-end control combining unit, a near-end and far-end subsystem, and a room division system. Background technique [0002] In the urban application environment, due to the rapid increase of mobile users and the increase of high-rise buildings, the traffic density and coverage requirements are also rising. In indoor environments such as large buildings, underground shopping malls, and underground parking lots, mobile communication signals are weak. It is very easy to form blind areas and shadow areas of mobile communication, resulting in mobile phones and other terminals that use mobile communication signals cannot be used normally. At present, the indoor distribution system can be used to improve the mobile communication signal in the indoor environment. Using the indoor distribution system, the mobile communication signal of th...
