Base Station Timing Adjustment for Long-Distance Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outlying areas such as seas, islands, deserts, and remote rural regions face low coverage in mobile communications networks, requiring numerous base station deployments, which is costly and inefficient.
Innovation Solution
Adjusting the downlink sending moment and/or uplink receiving moment of a base station to eliminate transmission delays caused by long-distance communication, thereby expanding coverage without altering existing network protocols or increasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If base stations are deployed in outlying areas to improve coverage, then coverage is improved, but deployment cost increases
Solution Approach 1:
The patent changes the timing parameters of base station operations by adjusting the downlink sending moment and uplink receiving moment. This time parameter adjustment allows the base station to accommodate round-trip transmission delays in long-distance coverage scenarios, enabling extended coverage without deploying additional base stations in outlying areas
2Area of stationary object
If base stations are deployed in outlying areas to improve coverage, then coverage is improved, but deployment complexity increases
Solution Approach 1:
The patent modifies operational parameters (timing moments) rather than physical deployment parameters. By adjusting when the base station sends and receives signals, the system achieves extended coverage without the complexity of physically deploying additional infrastructure in remote locations
Solution Approach 2:
The patent separates the coverage extension function from physical base station deployment. Instead of adding more base stations, it segments the solution into timing adjustment mechanisms that allow existing base stations to serve distant users through coordinated time shifts in downlink and uplink operations
3Area of stationary object
If transmission delay is eliminated by adjusting timing moments, then long-distance coverage is achieved, but synchronization complexity increases
Solution Approach 1:
The patent applies preliminary timing adjustments to the downlink sending moment and uplink receiving moment before actual data transmission occurs. By pre-calculating and setting these timing moments based on expected round-trip delays, the system eliminates transmission delay issues without requiring complex real-time synchronization mechanisms during operation

AI summary
The present invention provides a long-distance coverage method and a base station. The long-distance coverage method in the present invention includes: determining, by a base station according to an initial radius, a round trip delay, where the initial radius is a cell radius of an initial coverage area of the base station; adjusting, by the base station according to the round trip delay, a downlink sending moment and an uplink receiving moment between the base station and long-distance user equipment UE; and communicating, by the base station, with the long-distance UE based on an adjusted downlink sending moment and an adjusted uplink receiving moment. In embodiments of the present invention, a downlink sending moment and/or an uplink receiving moment of a base station are or is adjusted, to eliminate a transmission delay caused by long-distance communication and to implement long-distance coverage of the base station without changing an existing network protocol.
