Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, user equipment often faces challenges in transmitting uplink signals due to network resource burdens on serving cells, which can lead to failed transmissions when multiple devices are connected, causing power loss and potential signal interruption.
Innovation Solution
The method involves using network resources from neighboring cells to alleviate the burden on serving cells by determining and utilizing the cell with the lowest power loss for signal transmission, thereby ensuring fluent signal transmission and reducing power loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the serving cell allocates network resources to multiple user equipments, then the network coverage and service capability are improved, but the network burden on the serving cell increases and may cause transmission failures
Solution Approach 1:
The patent divides the network resource allocation function between the serving cell and neighboring cells. Instead of concentrating all resource allocation on the serving cell, the system segments the allocation across multiple cells, allowing user equipment to receive resources from neighboring cells when the serving cell is overloaded.
Solution Approach 2:
The patent introduces neighboring cells as intermediary resources. When the serving cell cannot allocate sufficient resources, neighboring cells act as mediators to provide alternative network resources to user equipment, reducing the burden on the serving cell while maintaining service capability.
2Productivity
If the serving cell allocates network resources to many user equipments, then more devices can be served, but user equipment may fail to transmit uplink signals due to lack of allocated resources
Solution Approach 1:
The patent implements dynamic resource allocation where user equipment can switch between serving cell resources and neighboring cell resources based on real-time availability. This dynamic approach ensures that transmission reliability is maintained even when the serving cell is overloaded, as equipment can access neighboring cell resources when needed.
Solution Approach 2:
The patent performs preliminary measurement and selection of neighboring cells with lower power loss before actual resource allocation. By pre-identifying suitable neighboring cells and their available resources, the system ensures that reliable alternative transmission paths are ready when the serving cell cannot provide sufficient resources.
3Speed
If uplink signals are transmitted through the serving cell, then the transmission path is direct, but power loss increases when the serving cell is congested
Solution Approach 1:
The patent changes the transmission parameter by selecting different cells (serving cell or neighboring cell) based on power loss measurements. When neighboring cells exhibit lower power loss, the system switches the transmission path to those cells, optimizing energy efficiency while maintaining transmission effectiveness.

AI summary
The present invention provides a method and an apparatus for transmitting an uplink signal, where the method includes: receiving information that is of a network resource and sent by a scheduling cell, where the scheduling cell is a neighboring cell of a serving cell to which the user equipment belongs; and sending the information of the network resource to the user equipment, so that the user equipment sends the uplink signal by using the network resource. In the method and apparatus for transmitting an uplink signal according to embodiments, the uplink signal is sent by allocating the user equipment with the network resource of the scheduling cell with a small power loss, thereby ensuring quality of the uplink signal as far as possible.
