Group-Based Beam Indication for Lower Wireless Signaling Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in network resource overhead and signaling flexibility, particularly in managing beam indications for multiple channels, resources, and component carriers, leading to unnecessary consumption of network, base station, and user equipment resources.
Innovation Solution
Implementing group-based beam indication and signaling techniques that allow a single beam indication to be applied across a group of channels, resources, bandwidth parts, or component carriers, thereby reducing the need for separate signaling for each individual element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate beam indications are used for each channel, resource, or component carrier, then signaling precision is improved, but network resource overhead increases
Solution Approach 1:
The patent combines multiple beam indications into a single group-based beam indication that can be applied to multiple channels, resources, or component carriers simultaneously. This merging approach reduces the total number of signaling messages required while maintaining the ability to provide precise beam control across multiple elements through the unified indication mechanism.
Solution Approach 2:
The group-based beam indication mechanism is designed to serve multiple functions simultaneously - it can indicate beams for different channel types (PDSCH, PUSCH, PUCCH), different resource types, and multiple component carriers through a single indication structure. This multi-functionality allows the system to maintain signaling precision across diverse elements without requiring separate dedicated indications for each.
2Manufacturing precision
If separate beam indications are used for each channel, resource, or component carrier, then beam control accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the processing of multiple beam indications into a single group-based indication processing step. Instead of separately processing individual beam indications for each channel or resource, the UE processes a unified group-based indication that covers multiple elements, thereby reducing computational complexity while preserving beam control accuracy through the consolidated indication data.
Solution Approach 2:
The patent segments the group of channels, resources, or component carriers into manageable units that can be collectively indicated by a single beam indication. This segmentation allows the system to maintain precise beam control for each individual element within the group while using a streamlined indication mechanism that reduces overall device complexity compared to handling each element separately.
3Adaptability or versatility
If individual signaling is used for each element, then signaling flexibility is improved, but energy consumption increases
Solution Approach 1:
The patent combines multiple individual signaling operations into a single group-based signaling event. By merging the indication of beams for multiple channels, resources, or component carriers into one signaling message, the system reduces the total number of transmission and reception operations required, thereby lowering energy consumption while preserving signaling flexibility through the configurable group structure that can be adapted to different scenarios.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink beam indication for at least one of a channel, a resource, a resource set, a bandwidth part, or a component carrier; and use the downlink beam indication for a group of channels, resources, resource sets, bandwidth parts, or component carriers. In some aspects, a UE may receive an indication of a spatial relation and multiple physical uplink control channel (PUCCH) resources to which the spatial relation is to be applied; and use the spatial relation to transmit on one or more PUCCH resources of the multiple PUCCH resources. Numerous other aspects are provided.
