Problems solved by technology

[0005] Based on this, it is necessary to use the BBU unit of the special digital baseband chip of the traditional technology. The manufacturer usually provides a single and high price, which greatly increases the cost of the BBU unit; and the special digital baseband chip is a chip coupled with software and hardware. The realization of functions is relatively limited, resulting in relatively limited user choices, providing an indoor distributed system, data transmission method and storage medium

Abstract

The invention relates to an indoor distributed system, a data transmission method and a storage medium. The indoor distributed system comprises a BBU unit, a protocol conversion CB unit, an expansionunit and a far-end unit; the CB unit is in communication connection with the BBU unit and the expansion unit, and the expansion unit is in communication connection with the far-end unit; the CB unit is used for respectively carrying out protocol conversion on the data received from the expansion unit and the BBU unit and sending timing information to the BBU unit; the timing information is used for indicating the BBU to send downlink data or receive uplink data; and the BBU unit is used for carrying out data communication with the CB unit according to the timing information and the data afterprotocol conversion. According to the indoor distributed system, the cost of the BBU unit can be reduced, and different function requirements of users for the BBU unit are met.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an indoor distributed system, a data transmission method and a storage medium. Background technique [0002] With the rapid increase of mobile users and more and more high-rise buildings, the traffic density and coverage requirements are also rising. These high-rise buildings are large in scale, and the radio signals of wireless communication are blocked and attenuated. In such high-rise buildings Difficult to communicate normally. In environments such as the low floors of large buildings, underground shopping malls, and underground parking lots, it is usually a blind spot. The indoor distributed system can use the indoor antenna distribution system to evenly distribute the signal of the mobile base station in every corner of the room, thereby ensuring ideal signal coverage in the indoor area and better improving the mobile communication environment in the bu...
