Embodiment Construction

[0041] In the following description, for purposes of illustration rather than limitation, specific details are set forth, such as particular architectures, interfaces, techniques, etc., in order to provide a thorough understanding of the present invention. It will be apparent, however, to those skilled in the art that the invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail. Additionally, individual functional blocks are presented in some of the figures. Those skilled in the art will appreciate that these functions may be implemented using separate hardware circuits, using software operating in conjunction with a suitably programmed digital microprocessor or general purpose computer, using application specific integrated circuits (ASICs), and / or using one or m...

Abstract

An embodiment of the invention provides a multiplex method of a communication signal, a wireless communication system and a radio equipment controller. Taking a CPRI (common public radio interface) as an example, in each embodiment provided in the invention, through bearing a plurality paths of CPRI links on a limited physical link (CPRI-MUX), generally on a path of high speed physical link, a physical bandwidth is fully utilized, a quantity of interconnection interfaces is reduced, system cost is reduced, and compatibility of a CPRI standard is maintained simultaneously. When the high speed physical link bandwidth is not enough, a physical link can be increased further.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of December 17, 2008 and an application number of 200810241623.2. technical field [0002] The invention relates to the communication field, in particular to a multiplexing method of communication signals, a wireless communication system and a wireless device controller. Background technique [0003] The radio base station system may be divided into a radio equipment controller (Radio Equipment Controller, REC for short) and a radio equipment (Radio Equipment, RE for short). The interface connecting the REC and the RE may be referred to as a REC-RE interface. [0004] The Common Public Radio Interface (CPRI for short) standard is an interface standard formulated by communication equipment manufacturers. In this standard, the REC-RE interface connecting the REC and the RE may be called a CPRI interface. [0005] The Open Base Station Architecture Initiative (OBSAI) s...
