Base Station Selecting Multiple User Equipments for Downlink Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in maintaining throughput rate and reliability of data transmission when the environment of a single user equipment deteriorates, as they primarily operate on a single user equipment without effective assistance from other devices.
Innovation Solution
A method and apparatus that utilize multiple user equipments to assist each other in transmitting data by detecting and selecting the best radio bearer for data transmission, even if the environment of the source or destination user equipment deteriorates, thereby ensuring continuous and reliable data transmission through mutual assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single user equipment is used for data transmission, then the system operation is simple, but the throughput rate and reliability fall sharply when the environment deteriorates
Solution Approach 1:
The patent combines multiple user equipments into a collaborative transmission system where one UE acts as the data transmission target and another UE assists in the transmission process. This merging of resources improves reliability by providing alternative transmission paths when the primary UE's environment deteriorates, while the base station coordinates this collaboration to manage system complexity.
Solution Approach 2:
The patent enables user equipments to serve multiple functions: a UE can be both a data transmission target and an assisting device for other UEs. This multi-functionality allows the system to dynamically allocate roles based on environmental conditions, improving overall reliability without proportionally increasing device complexity.
2Productivity
If multiple user equipments are used to assist data transmission, then the throughput rate and reliability improve, but the system complexity increases
Solution Approach 1:
The base station serves as an intermediary that coordinates the collaborative transmission between multiple user equipments. It manages the selection of assisting UEs, determines transmission paths, and controls the communication protocols, thereby enabling improved throughput rate through multiple UEs while centralizing the complexity management function.
Solution Approach 2:
The patent implements dynamic role assignment where user equipments can switch between being data transmission targets and assisting devices based on real-time environmental conditions. This dynamic flexibility allows the system to optimize throughput rate by selecting the best available UEs for each transmission task while adapting to changing conditions without permanent complexity increases.

AI summary
The present invention relates to a method and an apparatus used for communication, including: when a base station receives downlink data through a first system bearer of a first user equipment, detecting, by the base station, according to a context of the first user equipment stored by the base station itself, whether a radio bearer which is of other user equipment except the first user equipment and assists the first user equipment or the first system bearer in transmitting data exists in the base station; if the radio bearer exists, selecting, by the base station, from the first user equipment and the other user equipment except the first user equipment, at least one user equipment that transmits the downlink data; and sending, by the base station, the downlink data through a specified radio bearer corresponding to the at least one user equipment.
