Solution Overview
Problem
Current wireless communication systems face challenges in maintaining synchronization between base stations and user equipment regarding beam indications, leading to inefficiencies and resource wastage due to conflicts between different beam indication types.
Innovation Solution
The method involves transmitting a set of beam indications associated with various beam indication types from a base station to user equipment, allowing for the selection and transmission of a second beam indication type that is compatible or of higher priority, thereby maintaining synchronization and reducing processing and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple beam indication types are transmitted simultaneously, then beam indication completeness is improved, but synchronization reliability deteriorates due to conflicts between different beam indication types
Solution Approach 1:
The system dynamically selects which beam indication type to transmit based on the current beam indication type determined in previous communications. The base station adapts its transmission strategy by choosing from different beam indication types (first type indicating beam for downlink channel, second type indicating beam for uplink channel, third type indicating common beam) according to the dynamically determined current type, thereby maintaining synchronization while providing complete beam indications.
2Reliability
If beam indication conflicts are resolved through reestablishment, then synchronization is restored, but processing time and resource consumption increase
Solution Approach 1:
The system performs preliminary action by determining a current beam indication type before transmission conflicts occur. The base station uses this predetermined type information to select appropriate beam indications that are guaranteed to be compatible with the current state, preventing conflicts before they happen. This eliminates the need for time-consuming conflict resolution and reestablishment procedures.
3Productivity
If different beam indications are used for different channels, then channel-specific optimization is improved, but device complexity increases due to multiple beam indication types
Solution Approach 1:
The system applies local quality by using different beam indication types for different channels based on their specific requirements. The first beam indication type is used for downlink channels where the UE needs to receive signals, the second type is used for uplink channels where the UE needs to transmit signals, and the third type is used when a common beam applies to multiple channels. This localized adaptation optimizes each channel while the base station's control over type selection manages the overall complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a set of beam indications, associated with a set of beam indication types, for a set of beams to use for communication via a set of channels. The set of beam indications includes a first beam indication, associated with a first beam indication type, that indicates to use a first beam for communication via at least a first channel of the set of channels. The base station may select, based at least in part on the set of beam indication types, a second beam indication type for transmission of a second beam indication that indicates to use a second beam for communication via the first channel of the set of channels. The base station may transmit the second beam indication using the second beam indication type. Numerous other aspects are described.
