Problems solved by technology

[0003] However, in the prior art, transmission between the RRU (Radio Remote Unit, near-end unit) of the communication device and the BBU (Building Base band Unite, remote unit) needs to be performed through a feeder, and each transmission signal or reception signal corresponds to a Independent channels, and each independent channel needs to be equipped with a feeder, which makes the cost of communication equipment too high and the construction is inconvenient

Abstract

The present invention relates to the field of communications. Disclosed are a signal transmission method and device, which can reduce the number of feeders in a communication device and reduce costs of the communication device. The specific solution is: acquiring a first send signal and a second send signal; combining the first send signal and the second send signal into a transmit signal, and transmitting the transmit signal through a feeder from a near-end unit to a far-end unit; after the transmit signal is transmitted to the far-end unit, separating the first send signal and the second send signal from the transmit signal; adjusting the frequency of the second send signal to generate a second frequency-converted signal; and separately sending the first send signal and the second frequency-converted signal. The present invention is used in signal sending and signal receiving.

Description

technical field [0001] The present invention relates to the communication field, in particular to a signal transmission method and equipment. Background technique [0002] With the increasing demand for mobile data services and the continuous enrichment of mobile application content, in order to improve data transmission capabilities in the case of limited spectrum resources, MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) technology is widely used in the communication field. For example, an LTE (Long Term Evolution, long-term evolution) network, a WIFI (Wireless Fidelity, wireless broadband) network, and the like. MIMO technology is to transmit data through multiple antennas at multiple channels of the same frequency point, and to receive data through multiple antennas and channels, so that parallel data can be sent or received at the same time, which in turn improves the data transmission capability under limited spectrum resources. . [0003] Howev...
