Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing technologies face challenges in efficiently transmitting and receiving data, particularly in MIMO environments where densely distributed users with similar radio channel characteristics hinder system transmission efficiency due to interference and resource limitations.
Innovation Solution
The method involves user equipment (UEs) cooperating to share beams, with each UE determining a dedicated beam and a shared beam based on preferred beam information, and transmitting this information to the base station, allowing for simultaneous reception of UE-common and UE-specific data, enhancing data transmission efficiency.

Engineering Contradiction Analysis
1Productivity
If multiple UEs use dedicated beams in MIMO environment, then data transmission rate is improved, but system resource consumption increases and interference occurs between densely distributed users
Solution Approach 1:
The patent merges beam resources by allowing multiple UEs to share common beams for receiving common data (PBCH, PDSCH) while using dedicated beams only for UE-specific data. This combining approach reduces overall beam resource consumption while maintaining high data transmission rates for both common and dedicated data streams.
Solution Approach 2:
The patent implements multi-functionality by enabling beams to serve dual purposes: common beams handle broadcast and multicast data for multiple UEs simultaneously, while dedicated beams provide personalized data transmission. This universal beam structure optimizes resource utilization across different data types and user groups.
2Reliability
If dedicated beams are allocated to each UE, then UE-specific data reception is enhanced, but interference increases in densely distributed user scenarios
Solution Approach 1:
The patent segments beam allocation into two distinct categories: common beams for shared data transmission and dedicated beams for UE-specific data. This segmentation reduces interference by separating common data transmissions from user-specific transmissions, allowing dense user deployment while maintaining reliable UE-specific data reception.
Solution Approach 2:
The patent applies local quality by providing different beam qualities to different UEs based on their specific needs and channel conditions. UEs with poor channel conditions receive enhanced dedicated beams for reliable data reception, while UEs with good conditions can efficiently share common beams, optimizing overall system performance and reducing interference.
3Quantity of substance
If common beams are used for all UEs, then resource efficiency is improved, but UE-specific data transmission efficiency decreases
Solution Approach 1:
The patent segments data transmission into common data transmitted via shared beams and UE-specific data transmitted via dedicated beams. This segmentation ensures that resource efficiency is maintained for common data while UE-specific data transmission efficiency is preserved through personalized beam allocation.
Solution Approach 2:
The patent implements dynamic beam allocation where the system adaptively determines whether to use common or dedicated beams based on UE-specific channel conditions, data type, and system load. This dynamic approach optimizes the balance between resource efficiency and transmission efficiency for each UE and data stream.
