Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR specifications do not allow for beam-specific operations for multiple panels on user equipment (UE) to perform simultaneous downlink (DL) and uplink (UL) operations via multiple beam links, limiting the flexibility and efficiency of wireless communication.
Innovation Solution
The implementation of a method and apparatus that enable full power UL MIMO operation by dynamically allocating DL/UL operations based on beam-specific configuration information, including beam identifiers, slot, and symbol configurations, allowing for multi-beam operations between base stations and user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beam-specific operations are not allowed in current 5G NR specifications, then device complexity is reduced and ease of operation is maintained, but communication efficiency and flexibility deteriorate
Solution Approach 1:
The patent segments the communication system into multiple independent beam links, each with its own configuration information including beam identifiers, slot configurations, and symbol configurations. This allows separate control and optimization of each beam link while maintaining overall system coordination through the base station.
Solution Approach 2:
The patent implements dynamic beam-specific operations where configuration information can be changed independently for each beam link. The base station can dynamically allocate different DL/UL operations to different beam links based on channel conditions, traffic requirements, and interference levels, enabling adaptive optimization without increasing fundamental device complexity.
2Productivity
If simultaneous DL and UL operations are not allowed via multiple beam links, then interference is reduced and reliability is improved, but communication flexibility and throughput deteriorate
Solution Approach 1:
The patent applies local quality by allowing different operational modes (DL or UL) to be assigned to different beam links based on their specific conditions. Each beam link can be independently configured with appropriate slot and symbol patterns suited to its local channel characteristics, traffic demands, and interference environment, thereby optimizing overall system throughput while maintaining reliability through diversified operations.
3Adaptability or versatility
If beam-specific configuration information is implemented, then communication flexibility is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent implements a universal configuration framework where the base station maintains centralized control for generating and managing beam-specific configuration information. The configuration structure uses standardized elements (beam identifiers, slot configurations, symbol configurations) that can be applied across multiple beam links, providing flexibility through a unified multi-functional system rather than requiring separate complex processing for each beam.

AI summary
A method for a beam-specific operation between a base station (BS) and a user equipment (UE) is provided. The method comprises obtaining a configuration for at least one of a downlink (DL) reception or an uplink (UL) transmission, wherein the configuration comprises beam identifiers (IDs) and a slot and symbol configuration for respective ones of the one or more beam IDs. The method further includes performing, according to the configuration information, a DL operation or an UL operation.
