Abstract

The invention discloses a method for a baseband unit to reset a multi-level remote radio frequency unit. First, the baseband unit sets the reset bit and reset address in the reset information control word, and sends the reset information; then each remote The end radio frequency unit sequentially receives the reset information and detects it. If the detection result is a reset request and the reset address in the reset information is consistent with the identification number of the remote radio unit that detected the reset information or the reset address is global If the identification number is reset, the remote radio frequency unit is reset. The base station unit BBU of the technical solution of the present invention can independently reset the RRUs without affecting the work of other RRUs, improves the reliability of the system, and avoids the impact of local failures on the global business, and supports the entire link It has a reset function and has good compatibility with the existing technology from the scheme, and the realization is simple and convenient.

Description

technical field

[0001] The invention relates to a method for a baseband unit in a wireless communication system to reset a multistage remote radio frequency unit. Background technique

[0002] In recent years, the development of wireless communication system architecture has gradually evolved into such a trend: separate the BBU (Base Band Unit, baseband unit) from the RRU (Remote Radio Unit, remote radio frequency unit), and use long-distance transmission means (such as optical fiber , cables) connect the BBU with multiple RRUs, and then place the RRUs in various places where they are needed. This architecture improves the flexibility of networking on the one hand, and reduces the maintenance cost of the network on the other hand. Therefore, this architecture is more and more recognized by users, and there are more and more application occasions. In recent years, this architecture has been written into certain industry standards, such as OBSAI (Open Base Station Architectu...
