Uplink Transmission Continuity Reporting for Joint Channel Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack efficient mechanisms for a user equipment (UE) to report its uplink transmission continuity capability, such as phase or amplitude continuity, to the base station, which hinders joint channel estimation and increases processing overhead and latency.
Innovation Solution
The UE transmits its uplink transmission continuity capability information, including phase or amplitude continuity, to the base station, allowing for joint channel estimation and reducing signaling overhead and latency by maintaining phase continuity across multiple resource blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE transmits detailed uplink transmission continuity capability information to the base station, then the base station can perform accurate joint channel estimation, but the signaling overhead and processing latency increase
Solution Approach 1:
The patent extracts only the essential continuity capability information (phase continuity and amplitude continuity indicators) from the complete UE capability set and transmits only this extracted information to the base station. This selective extraction maintains channel estimation accuracy while minimizing signaling overhead and processing latency by excluding unnecessary capability details.
Solution Approach 2:
The patent transforms the continuous phase and amplitude characteristics into discrete indicator parameters (e.g., phase continuity indicator, amplitude continuity indicator) that can be efficiently transmitted. This parameter transformation enables the base station to perform joint channel estimation with high accuracy using compact signaling, thereby reducing both overhead and processing time.
2Measurement precision
If the UE maintains phase continuity across multiple resource blocks, then joint channel estimation accuracy improves, but the device complexity and processing requirements increase
Solution Approach 1:
The patent implements phase continuity maintenance across multiple resource blocks as a preliminary action before channel estimation occurs. By pre-establishing phase continuity and reporting this capability to the base station, the UE enables the base station to perform joint channel estimation without requiring complex real-time processing during the estimation itself, thereby reducing instantaneous device complexity.
3Productivity
If the UE reports comprehensive uplink transmission capability information, then the base station can optimize resource allocation, but the signaling overhead increases
Solution Approach 1:
The patent extracts only the critical uplink transmission continuity capability parameters (phase continuity indicator, amplitude continuity indicator, and applicable resource block information) from the complete UE capability set. This selective extraction enables the base station to optimize resource allocation for uplink transmissions while minimizing signaling overhead by excluding redundant capability information.
Solution Approach 2:
Instead of the base station requesting comprehensive capability information and the UE providing it, the patent inverts the approach by having the UE proactively report only the essential continuity capability information that is most relevant for resource allocation optimization. This inversion reduces signaling overhead while maintaining resource allocation efficiency.

AI summary
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmission continuity capability reporting. A user equipment (UE) may generate or otherwise determine UE capability information related to a capability of the UE to maintain a transmission continuity for one or more uplink transmissions across a wireless channel. The UE may send an indication of the transmission continuity capability information, which may be based on a parameter of continuity, an accuracy of continuity, or both, to a base station (BS). The UE may transmit the one or more uplink transmissions, including reference signals, data messages, or both, in accordance with the transmission continuity capability. For example, the UE may maintain a transmission continuity, a transmit power, or both for transmissions across multiple resource blocks (RBs). The BS may perform a joint channel estimation procedure based on the one or more uplink transmissions.
