Downlink and uplink transmission method and transmission device for mobile communication signals in built-up area

Abstract

The invention relates to a downlink and uplink transmission method and a transmission device for mobile communication signals in a built-up area. The method comprises the steps that 1, a baseband processing unit at a system side sends a downlink communication photosignal and transmits to an optical transceiver at the system side; 2, the optical transceiver sends the received downlink communication photosignal to a family communication unit of each user family at a user side by a passive optical network; 3, each family communication unit transforms the downlink communication photosignal into a downlink communication electric signal and sends the downlink communication electric signal to a corresponding user. The transmission method and the transmission device have the irreplaceable advantages that no feeder line exists, the construction is simple, the networking is flexible and fast, the adjusting is easy, the cost is reduced, the coverage effect is good, and the like, and have wide prospect for equipment manufacturers and mobile communication operators especially under the condition of fiber to the home at the present stage.

Description

technical field [0001] The invention relates to a wireless signal coverage method, in particular to a downlink and uplink transmission method and transmission device for mobile communication signals in densely built areas. Background technique [0002] The current mobile network networking methods are macro base station, micro cell, pico cell, indoor distribution, femto and other forms. The main problem at present is that the traditional mobile network construction is difficult and expensive in terms of network infrastructure and construction coordination. , high later maintenance costs and other disadvantages. In addition, for large residential buildings, office buildings, etc., there are likely to be dead spots and holes in network coverage; [0003] The current communication mode in the mobile communication network is the baseband processing unit (BBU) and the remote radio unit (RRU) (the current technology is also connected by optical fiber, but the location of the RRU ...

[0002] The current mobile network networking methods are macro base station, micro cell, pico cell, indoor distribution, femto and other forms. The main problem at present is that the traditional mobile network construction is difficult and expensive in terms of network infrastructure and construction coordination. , high later maintenance costs and other disadvantages

In addition, for large residential buildings, office buildings, etc., there are likely to be dead spots and holes in network coverage;

[0003] The current communication mode in the mobile communication network is the baseband processing unit (BBU) and the remote radio unit (RRU) (the current technology is also connected by optical fiber, but the location of the RRU cannot enter the user's home, and a new BBU is also required. The optical fiber between the RRU and the RRU requires a new antenna. The wireless indoor distribution system is that the RRU RF signal is connected through a feeder line, and the feeder line needs to be laid to the antenna, which is difficult to construct.
