Problems solved by technology

[0008] As the LTE bandwidth or the number of antennas increases, the optical port rate will increase proportionally, which will greatly increase the hardware cost of the device; and, as the optical port rate continues to increase, the current hardware equipment will not be able to meet the corresponding optical port rate. port rate requirement

Embodiment Construction

[0034] The basic idea of ​​the present invention is: set the compression flag; set the compression algorithm flag to specify the compression algorithm when compression is needed; When receiving the data stream, determine whether the data stream needs to be decompressed through the obtained compression flag, and then directly obtain the original data stream, or first decompress according to the specified compression algorithm of the compression algorithm flag, and then obtain the original data stream .

[0035] Here, the compression flag bit is used to identify whether the original data stream undergoes compression processing, and the compression flag bit is sent separately before sending the data stream. The compression flag can be implemented with one bit, for example: 0 indicates that the original data stream is not compressed, and 1 indicates that the original data stream is compressed. The setting of the compression flag enables the receiver to know whether the received d...

Abstract

Disclosed is a method for data compression, comprising: determining whether a data stream to be sent currently is required to be compressed, if not required, setting a compression flag bit as not performing compression processing, and sending the compression flag bit and the original data stream sequentially; if required, setting the compression flag bit as performing compression processing; setting a compression algorithm flag bit as a designated compression algorithm, and compressing the original data stream by using the designated compression algorithm; first sending the compression flag bit, and then packaging the compressed data stream and the set compression algorithm flag bit together for sending. Meanwhile, disclosed are a method for data decompression, and an apparatus and a system corresponding thereto. With the present invention, data compression efficiency is improved without increasing the device cost, so as to satisfy the demand for a higher optical interface rate.

Description

technical field [0001] The invention relates to data compression and decompression technology, in particular to a data compression and decompression method, device and system in a wireless communication system. Background technique [0002] In a long term evolution (LTE, Long Term Evolution) wireless communication system, a radio access network is composed of an evolved node B (eNodeB, Evolved NodeB). The eNodeB is further composed of an evolved indoor baseband processing unit (eBBU, Evolved Building Base band Unit) and an evolved remote radio unit (eRRU, Evolved RadioRemote Unit). Protocols such as a radio frequency interface (CPRI, Common Public Radio Interface) or an open wireless interface (ORI, Open Radio Interface) perform data interaction. [0003] In the CPRI protocol, a radio equipment controller (REC, Radio Equipment Control) corresponds to an eBBU, and a radio frequency equipment (RE, Radio Equipment) corresponds to an eRRU. The CPRI protocol stipulates the inte...
