Embodiment Construction

[0106] The basic idea of ​​the present invention is to separate the baseband part and the radio frequency part of the base station to form a baseband unit (BBU, baseband Unit) and a radio frequency unit (RFU, Radio Frequency Unit), and the RFU is provided with a device that is connected to the BBU and transmits data information. The baseband radio frequency interface forms a split base station system. Moreover, on the basis of the separation of BBU and RFU, the BBU capacity is further divided, and each unit is also placed separately, so that each baseband unit can support the minimum configuration, and multiple baseband units can be combined to support the macro base station. capacity. In the present invention, the transmission unit, main control and clock synchronization unit, baseband signal processing unit and interface unit of the BBU are highly integrated and designed, such as integrated on a single board, and set in a small BBU box. Form a field replaceable unit; throug...

Abstract

The invention discloses a split-type base station system and a networking method and a baseband unit thereof. In the system, a baseband unit (BBU) of a base station is separated from a radio-frequency unit (RFU), and the RFU is equipped with a baseband radio-frequency interface which is intercommunicated with the BBU to transmit data information, thereby forming the split-type base station system. Additionally, besides the separation of the BBU from the RFU, the BBU capacity is divided and each unit is placed separately. By the capacity-expansion interface and baseband radio-frequency interface provided by the BBU interface units, the networking and capacity-expansion of BBU are realized with flexibility, the occupied area is reduced, the operating cost is reduced, and the operational reliability of the base station system is improved.

Description

technical field [0001] The invention relates to base station technology, in particular to a split base station system, its networking method and base band units forming distributed base stations. Background technique [0002] In the mobile communication system, the base station is an important part of the mobile communication network. It is connected between the user terminal and the base station controller, and is used to send and receive wireless signals, so that the user terminal can access the wireless network, and at the same time complete the communication with the base station controller. information interaction. Figure 1 is a schematic diagram of the composition and structure of a base station in a mobile communication system. As can be seen from Figure 1, the base station mainly includes: [0003] The interface between the base station and the base station controller is used to complete the interface function between the base station and the base station controller...
