Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminals have limited flexibility in uplink transmission on unlicensed frequency bands due to fixed transmission modes, lacking support for frequency hopping.
Innovation Solution
Implementing a resource transmission method that allows terminals to determine an uplink transmission mode based on configuration or scheduling information, supporting or not supporting frequency hopping on unlicensed frequency bands, enhancing flexibility by enabling various frequency hopping patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed uplink transmission mode is used on unlicensed frequency bands, then the transmission protocol is simple and easy to implement, but the terminal flexibility is poor and frequency hopping cannot be supported
Solution Approach 1:
The patent applies dynamics by enabling the terminal to dynamically switch between different uplink transmission modes (frequency hopping and non-frequency hopping modes) based on received indication information. This allows the system to adapt to different channel conditions and requirements on unlicensed frequency bands, improving terminal flexibility while maintaining protocol manageability through standardized switching mechanisms.
Solution Approach 2:
The patent implements parameter changes by introducing configurable transmission mode parameters that can be adjusted through indication information from the network side. The terminal can change its transmission behavior (frequency hopping enabled or disabled) based on these parameters, allowing the system to optimize performance for different scenarios without requiring completely different protocols.
2Productivity
If frequency hopping is not supported on unlicensed frequency bands, then the transmission mode is fixed and easy to manage, but transmission efficiency and adaptability are limited
Solution Approach 1:
The patent applies universality by designing a unified uplink transmission framework that can handle both frequency hopping and non-frequency hopping scenarios through a single protocol structure. The network side sends indication information to select the appropriate mode, making the system multi-functional and capable of achieving high transmission efficiency in both frequency hopping and non-frequency hopping conditions without requiring separate protocols.
3Adaptability or versatility
If dynamic grant based uplink transmission is used, then transmission parameters can be dynamically indicated, but on unlicensed frequency bands only fixed transmission modes are permitted according to current protocols
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of indication information sent by the network side to the terminal. This intermediary enables dynamic transmission mode selection on unlicensed frequency bands while maintaining protocol compliance, as the switching is controlled through standardized signaling rather than ad-hoc modifications. The intermediary allows dynamic grant-based transmission to work properly on unlicensed bands by mediating between the terminal's capability and protocol requirements.

AI summary
A resource transmission method, a resource transmission apparatus, and a communications device. The resource transmission method is applied to a terminal and includes: obtaining first information, where the first information includes at least one of configuration information and scheduling information for uplink transmission; and determining an uplink transmission mode based on the first information, where the uplink transmission mode supports frequency hopping on an unlicensed frequency band, or the uplink transmission mode does not support frequency hopping on the unlicensed frequency band.
