Embodiment Construction

[0066] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0067] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways than described here; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, and Not all examples.

[0068] In practical applications, in order to meet the needs of operators for co-sited, co-located, multi-carrier and large-bandwidth applications, hardware channels can be added (for example, to cover 300M bandwidth signals, 150M before channel 1 transmission, 150M after channel 2 transmission),...

Abstract

The invention relates to a remote transmission coverage method and system and a remote unit. The method comprises the following steps: receiving a plurality of carrier signals; carrying out processing based on the plurality of carrier signals, and obtaining a plurality of paths of radio frequency signals; and carrying out power amplification on the plurality of paths of radio frequency signals, inputting the amplified signals into a filtering integrated module in a remote unit to carry out filtering on the signals, combining the filtered plurality of paths of radio frequency signals based on signal types of the plurality of paths of radio frequency signals, generating a radio frequency signal with a target bandwidth, and sending the radio frequency signal to an antenna, wherein the filtering integrated module comprises a filter, a circulator and a bridge which are connected in sequence. Therefore, large-bandwidth signal emission of each antenna port is realized, the large-bandwidth and high-power signal coverage requirement is met, the networking cost is reduced, the networking convenience is improved, and the communication quality is improved.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a remote transmission coverage method, system, and remote unit. Background technique [0002] With the advent of the 5G era, major communication manufacturers have developed various types of 5G products such as RRU (RemoteRadio Unit, radio frequency remote unit), DAS (Distributed Antenna System, distributed antenna system) or repeaters. Currently, RRU , DAS or repeater supports carrier operating bandwidth generally between 100M and 200M, which cannot meet the needs of operators for co-site co-location and multi-carrier large-bandwidth applications. [0003] In related technologies, by adding hardware channels (for example, 300M bandwidth signals need to be covered, 150M before channel 1 transmission, and 150M after channel 2 transmission), and then each channel has a separate external antenna. Since each antenna has only one frequency band signal, so 2 anten...
