Abstract

The invention provides a transmission method and communication equipment, and the communication equipment comprises a first port, a second port, a third port, at least one branching unit, and SUL receiving equipment which is used for supporting an SUL function. The first port is connected with a multi-channel antenna supporting multiple frequency bands and the at least one branching unit; the second port is connected with a first RRU of the first network and the at least one branching unit, the third port is connected with a second BBU of a second network and the SUL receiving device, the at least one demultiplexer is connected with the SUL receiving device, and communication protocols of the first network and the second network are different. According to the scheme, by means of the communication equipment, when SUL receiving equipment and RRUs supporting different network frequency bands are deployed at the same station, shunt transmission of uplink signals of multiple frequency bands can be achieved, interference caused by stray downlink signals in a network can be filtered out, and therefore the isolation degree requirement is met.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a transmission method and communication equipment. Background technique [0002] At present, it has been determined that the middle and high frequency bands of 3.3GHz-3.6GHz and 4.8GHz-5.0GHz can be divided into working frequency bands of the fifth-generation mobile communication technology (5th-Generation, 5G) system. However, the higher the frequency band, the worse the coverage capability and the limited uplink power of the terminal. Therefore, uplink coverage is more likely to become a bottleneck. How to improve the uplink performance of the 5G system has become an important goal of deploying the 5G system. [0003] In order to improve the uplink performance of the 5G system, the current response strategy is to use 5G uplink and downlink decoupling technology, also known as supplementary uplink (Supplement UL Link, SUL), to break the restriction that the uplink ...
