Embodiment Construction

[0017] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0018] The invention provides a 4G TDD radio frequency near-end and far-end RU system synchronization device based on envelope detection technology, which is simple, practical and low in cost.

[0019] The main function of the present invention is to keep the uplink and downlink switching time of the radio frequency remote coverage unit RU (Remote unit) consistent with the base station in the TDD system, that is, to enable the RU to find out the first switching time point and the second switching time point position, so that the RU can amplify and cover the coupled TDD signal from the base station without causing interference.

[0020] For the whole TDD synchronous device, its key features are: including input ports and output ports. The TDD synchronization device also includes: a synchronization receiving module ...

Abstract

The invention provides a TDD synchronization device for 4G / 5G, which comprises an HUB and an RU; the HUB acquires TDD configuration information and a TDD downlink radio frequency signal from information source equipment; the HUB transmits TDD ratio information to the RU, the HUB converts a TDD synchronization pulse generated by envelope detection into a radio frequency pulse through a switch and transmits the radio frequency pulse to the RU for detection recovery, and the RU recovers a TDD switching signal according to the radio frequency pulse transmitted by the HUB and the TDD ratio and participates in switching control of radio frequency uplink and downlink. According to the invention, envelope detection is adopted, the implementation is simple, the cost is low, and the synchronization precision of low-power signals or unstable-power signals is difficult to guarantee. And the practicability is high for specific scenes.

Description

technical field [0001] The present invention relates to the technical field of TDD synchronization, in particular to a TDD synchronization device for 4G / 5G. Background technique [0002] With the development of information technology and the increasing demands of users, mobile communication technology has become a research hotspot with the greatest development potential and the broadest market prospect in the contemporary communication field. At present, 4G is the main mobile communication technology, and 4G is divided into FDD and TDD. [0003] TDD is instant division duplex, and the transmission and reception of signals are carried out in different time slots of the same frequency channel, and are divided between each other with a certain guaranteed time. To put it simply, it is a two-way "traffic flow" running on a "one-way street", and the traffic can only be controlled by time, allowing the download traffic to pass for a while, and the upload traffic to pass for a whil...
