Indoor distributed system, data transmission method and storage medium

Abstract

The application relates to an indoor distributed system, a data transmission method and a storage medium. The indoor distributed system includes: a BBU unit, a protocol conversion CB unit, an extension unit and a remote unit, the CB unit communicates with the BBU unit and the extension unit respectively, and the extension unit communicates with the remote unit Communication connection; the CB unit is used to perform protocol conversion on the data received from the extension unit and the BBU unit, and send timing information to the BBU unit; the timing information is used to indicate the BBU The unit sends downlink data or receives uplink data; the BBU unit is used to perform data communication with the CB unit according to the timing information and data after protocol conversion. The indoor distributed system can reduce the cost of the BBU unit and meet different functional requirements of users for the BBU unit.

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...
