Problems solved by technology

[0004] In this traditional transmission mode, the transmission bandwidth utilization rate of the CPRI interface is only 50% because the inserted filling bits do not carry baseband digital signals. In the future distributed base station architecture with increasing demand for optical fibers, the transmission bandwidth utilization rate of the CPRI interface is too high. Low

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] The embodiment of the present invention provides a data transmission method. By simulating the TDD time division duplex transmission mode of the air interface on the CPRI interface, one optical fiber is time-division multiplexed for uplink and downlink transmission, so as to improve the utilization rate of the transmission bandwidth of the CPRI interface.

Abstract

The embodiment of the present invention discloses a data transmission method, which is applied in a TDD system, including: before the arrival of a downlink period, the REC sends the first part of the downlink data of the downlink period to the RE; periodically sending the second part of the downlink data of the downlink period to the RE, the second part and the first part constitute all the downlink data of the downlink period; the RE receives the downlink data of the downlink period The first part and the second part; the RE sends the first part and the second part as downlink data through the air interface in the downlink period. Correspondingly, the embodiment of the present invention also discloses a base station, which can effectively improve the utilization of the transmission bandwidth of the CPRI interface and effectively improve the utilization rate of the spectrum resources of the air interface.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method and a base station. Background technique [0002] CPRI (CommonPublicRadioInterface, common public radio interface) is an interface standard between REC (RadioEquipmentController, radio equipment controller) and RE (RadioEquipment, radio equipment) in wireless base station equipment developed by several communication equipment manufacturers. The base station is divided into products and independently develops REC and RE technologies. According to the definition of the CPRI standard, there is a clear division of functions between REC and RE, where REC is related to network interface transmission, wireless base station control and management, and digital baseband processing, while RE is related to analog radio frequency functions, such as filtering, modulation, frequency Conversion is related to power amplification. [0003] CPRI interface devices REC and RE ca...
