Multi cell cellular base station system and data stream transmission method

Abstract

The invention discloses a multi-deme comb base station system and data flow transmitting method in the field of communicating. It time-division multiplies the base band signals and introduces the one or above exchanging plates which are connected with the base band processing module by A bus and connected with the radio frequency processing module by B bus.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission technology between a base station baseband module and a radio frequency module with multiple cells. Background technique [0002] In the 1960s, Bell Laboratories and other units in the United States proposed the concept of cellular mobile communication. However, its complex control system, especially the control of the mobile station, was not developed for cellular mobile until the 1970s with the maturity of semiconductor technology, the development of large-scale integrated circuit devices and microprocessor technology, and the wide application of surface mount technology. The realization of communication provides the technical basis. Today, cellular mobile communication has developed from the second generation Global System for mobile Communication (GSM for short) to Wideband Code Division Multiple Access (WCDMA for short). The third generation mobile communicati...

Problems solved by technology

[0009] In practical application, the above solution has the following problems: For the former interface, the connection relationship between the baseband processing module and the RF processing module is fixed, and there is only one link, which does not have flexibility; If one component fails on the road, the entire link cannot be used

If the number of cells is large, there will be too many interconnections and the hardware design will be very complicated.

When N=12, 144 connections need to be established, which will cause waste of resources and is difficult to achieve in practical applications

[0011] The main reason for this situation is that the data interface design between the existing baseband processing module and the radio frequency processing module, or the connection relationship is single, lacking the necessary backup; or the connection is too complicated to be applied in practice
