Embodiment

[0041] According to the network coverage requirements of the TD-SCDMA communication standard, the current signal coverage adopts more coverage methods in which BBUs and RRUs are connected. According to the Ir interface protocol proposed by China Mobile, RRU needs to support two optical port transmission rates of 1.25Gbps and 2.5Gbps. For the software in the TD-SCDMA radio remote unit, a set of software can be designed to support two optical port transmission rates at the same time, automatically detect, and automatically adopt different data transmission methods according to different optical port transmission rates. In general, the downlink and uplink design processes of the method for automatic detection and application of the optical port transmission rate of the present invention are as follows:

[0042](1) In the downlink, for the data received by the optical port, the 1.25Gbps data is transmitted according to the transmission rate of the 2.5Gbps optical port, and is conv...

Abstract

The invention relates to an automatic detection and application method of optical port transmission rate, which can realize two types of selective transmission of optical rate and comprises the steps of: 1, in a downlink, transmitting 1.25Gbps data according to 2.5Gbps, and converting the 1.25Gbps data into two paths of data with parallel high-low levels through a DDR (Double Data Rate) module; judging optical port transmission rates and then generating corresponding indicating signals; and respectively selecting all carriers as required from a plurality of antenna carriers for the two types of optical port transmission rates, and transmitting to a DUC (Digital Up Converter) module for transmitting out of a base band; and (2) in an uplink, inserting a plurality of carriers into corresponding antenna carriers according to the indicating signals; and then dividing the 1.25Gbps data into two same high-low level data, transmitting the data out of the base band through the DDR module to combine the data into a string and converting a processing chip. The invention is beneficial to reducing research and development cost and maintenance cost in a large scale, and adaptively detects the optical transmission rate through software without excessive manual intervention.

Description

technical field [0001] The invention relates to a TD-SCDMA digital cellular mobile communication network transmission technology in a mobile communication system, in particular to a software implementation method in a programmable chip supporting automatic detection and application of optical port transmission rate based on Ir protocol. Background technique [0002] In the last 20 years of the 20th century, modern mobile communication technology has gone through two stages: the first generation (analog system) and the second generation (narrowband digital system). [0003] Since the 1990s, mobile communication has developed at a very high speed. In 1999, in the communication equipment market, the share of mobile communication products exceeded 50% of the communication products. Moreover, this proportion is gradually increasing. The gradual popularization of handsets has brought a strong demand for personalized communications, and the rapid development of the Internet has b...
