Uplink Control Signaling for Unused CG PUSCH Occasion Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in appropriately reporting a dynamic indication of unused CG PUSCH occasions, leading to potential issues with resource utilization efficiency and processing in licensed and unlicensed spectra.
Innovation Solution
A terminal is equipped with a control section that determines uplink control information based on the presence or absence of support for transmission of first information, considering the operating frequency band and specific control parameters, and a transmission section that transmits this information to the base station.

1Productivity
If dynamic indication of unused CG PUSCH occasions is implemented, then resource utilization efficiency is improved, but device complexity increases due to additional control sections and transmission procedures
Solution Approach 1:
The control section integrates the determination of uplink control information with the existing terminal structure, combining the dynamic indication function with resource management operations. This merging approach enables the terminal to report unused CG PUSCH occasions while utilizing existing structural elements, thereby improving resource utilization efficiency without proportionally increasing device complexity
Solution Approach 2:
The terminal dynamically determines whether to transmit first information indicating unused uplink signal occasions based on real-time conditions such as operating frequency band and control parameter configuration. This dynamic adaptation allows the system to optimize resource utilization efficiency in different scenarios while managing complexity through conditional operation rather than always-on complex processing
2Measurement precision
If support for transmission of first information is added, then reporting accuracy of unused CG PUSCH occasions is improved, but processing time increases
Solution Approach 1:
The terminal performs partial processing by determining uplink control information based on specific conditions (operating frequency band and control parameter configuration) rather than always executing full processing routines. This partial action approach improves reporting accuracy when needed while reducing processing time in scenarios where the additional information transmission is not required
Solution Approach 2:
The system changes processing parameters based on operating conditions, specifically adjusting whether first information is transmitted based on the operating frequency band (licensed vs. unlicensed) and control parameter configuration. This parameter adaptation enables accurate reporting of unused CG PUSCH occasions in appropriate scenarios while minimizing processing time by avoiding unnecessary processing in other scenarios

AI summary
A terminal comprising: a control unit which determines uplink control information on the basis of the presence or absence of support for transmission of first information that specifies the occasion of an unused uplink signal, the support being defined according to the fact of being a licensed spectrum or the fact that a specific control parameter has not been set; and a transmission unit which transmits the uplink control information.
