Abstract

The invention discloses a method and a device for transmitting and receiving data. The method for transmitting data comprises the following steps of: respectively compressing data of each antenna of a data transmitting end to obtain the compressed data, and caching the compressed data into different antennae, wherein the compressed data comprises valid data intercepted from corresponding antenna in the compression process and an interception index, and the interception index is used for indicating an interception start bit; reading the compressed data cached in each antenna, converting bit width of the compressed data into a bit width value required by framing, forming a basic frame with the compressed data of which bit width is converted, and transmitting the basic frame. The method provided by the invention compresses the data to be transmitted, and correspondingly decompressed the data at a receiving end, so that link loading rate is improved without using an optical module which supports high data rate, and cost is effectively saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for sending and receiving data based on the CPRI protocol. Background technique [0002] The Common Public Radio Interface CPRI (Common Public Radio Interface) Alliance is an industrial cooperation organization dedicated to the formulation of main interface specifications between the radio equipment control center REC (Radio Equipment Controller) inside the radio base station and the radio equipment RE (Radio Equipment). The CPRI protocol formulated by it is used for the general interface between base station and radio frequency in wireless communication base stations. The protocol is divided into physical layer and data link layer horizontally; vertically divided into user data plane, control management plane and synchronization plane. In the CPRI protocol, user platform data is transmitted in IQ data mode. Each IQ data stream corresponds to the data o...
