Embodiment Construction

[0030] Embodiments of the present invention provide a CPRI-based data transmission method, a baseband processing unit, and a communication system, which can realize the multi-communication standard support function of the BBU without changing the existing networking mode.

[0031] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without 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.

Abstract

An embodiment of the invention discloses a wireless communication method and a distributed base station system, which relates to the field of communication and can realize multi-communication-system support functions of BBUs (baseband units) on the premise of keeping existing networking modes unchanged. A data transmission method based on CPRI (common public radio interface) includes: transmitting the BBU of the second communication system to second control data of at least one radio remote unit (RRU) to convert similar-CPRI type combined data and transmitting the combined data to the BBU of the first communication system through similar-CPRI type channels; restoring the combined data received by the BBU of the first communication system to be second control data, transmitting the second control data and the first control data to at least one RRU through CPRI channels so that at least one RRU supports data uploading and/or downloading of the first communication system and the second communication system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless communication method and a distributed base station system. Background technique [0002] The current 3G network uses a large number of distributed base station architectures, that is, using a radio remote unit (Radio Remote Unit, referred to as RRU) and a baseband processing unit (BaseBand Unit, referred to as BBU) connected by optical fibers, such as figure 1 shown. One BBU can support multiple RRUs, and the BBU+RRU multi-channel solution can well solve the indoor coverage problem of large venues. The RRU and the BBU are respectively responsible for the radio frequency processing part and the baseband processing part of the base station. They are installed independently, placed separately, and connected through electrical or optical interfaces to form a distributed base station form. [0003] The technical feature of RRU is that the base station is divided into tw...
