Ethernet-based radio remote data transmission method

Abstract

The invention provides a method and device for sending and receiving data between the radio equipment (RE) and radio equipment controller (REC) of a radio base station through the Ethernet. The method for sending data comprises the following steps: adapting the data frames, meeting the radio remote protocol, of a physical adaptation layer to obtain data frames suitable for the physical layer transmission of the Ethernet; and sending the adapted Ethernet data frames on the physical layer of the Ethernet.

Description

technical field

[0001] The present invention relates to wireless communication, in particular to a method and device for transmitting and receiving data between a radio remote unit and a baseband processing unit. Background technique

[0002] In some current wireless access networks such as 3G, Wimax and LTE (Long Term Evolution), base stations are configured as centralized nodes with most components located at a central location. However, radio base stations can also be configured in a distributed architecture. For example, a distributed radio base station may take the form that one or more radio equipment (RE) parts are connected to a radio equipment controller (REC) part through a radio base station internal interface.
