UL Tx Capability Reporting for Dual-Transmitter Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent understanding of uplink transmitter switching behaviors between terminals and network-side devices leads to errors in uplink transmission, as existing methods lack clarity on how to report and interpret additional UE capabilities for dual-Tx operations.
Innovation Solution
A terminal reports capabilities to a network-side device using different reporting granularities, including information about target band pairs, bands, and identification information to ensure a consistent understanding of UL Tx switching behaviors, thereby improving transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple UE capabilities are introduced to support UL Tx switching, then the functionality and versatility of the terminal is improved, but inconsistencies and errors in understanding UL Tx switching behaviors between terminal and network-side device occur
Solution Approach 1:
The patent segments the capability reporting into multiple distinct capability indicators (first capability, second capability, third capability) that can be reported independently. Each capability corresponds to specific UL Tx switching behaviors under different conditions, allowing the network to understand terminal capabilities in a structured, granular manner that reduces interpretation inconsistencies.
Solution Approach 2:
The patent introduces multiple capability parameters (first capability indicating support for second Tx within first switching period, second capability indicating support for first Tx within second switching period, third capability indicating support for both Txs simultaneously) that change the state of capability representation. These parameter changes enable precise description of different UL Tx switching scenarios, improving both versatility and consistency.
2Measurement precision
If detailed capability information is reported for different band pairs and switching periods, then the precision of UL Tx switching behavior understanding is improved, but the complexity of capability reporting increases
Solution Approach 1:
The patent divides capability reporting into multiple segmented capability indicators, each covering specific aspects of UL Tx switching behavior. This segmentation allows precise reporting of different capability dimensions (single Tx switching, dual Tx switching, switching period support) without requiring a single complex capability field, thereby improving precision while managing complexity through structured decomposition.
Solution Approach 2:
The patent adds another dimension to capability reporting by introducing multiple capability indicators that can be combined in different ways. Instead of a single flat capability field, the system uses multiple capability dimensions (first capability, second capability, third capability) that can be reported independently and combined to describe complex UL Tx switching behaviors, enhancing precision without linearly increasing complexity.

AI summary
An information reporting method and apparatus, and a terminal are disclosed. The method includes: reporting, by a terminal, first information to a network-side device, where the terminal includes a first Tx and a second Tx, and the first information includes: a first capability used to indicate that the terminal supports the second uplink transmitter Tx performing uplink transmission within a first switching period reporting the first capability based on at least one of the following: information of a target band pair; information of at least one band in the target band pair; identification information of a first band; or information of a target band list.
