User Terminal UCI Resource Allocation via Beta Offset Sets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation mobile communication systems, user terminals face challenges in determining the appropriate resources for transmitting uplink control information (UCI) on the Physical Uplink Shared Channel (PUSCH), leading to potential deterioration in communication throughput and spectral efficiency due to the lack of a method to specify the correct set of beta offset values.
Innovation Solution
A user terminal is equipped with a transmitting section that transmits uplink data and control information on an uplink shared channel, and a control section that specifies and controls the resources for UCI transmission based on selected beta offset values from configured sets, using a set designation field within the Downlink Assignment Indicator (DAI) to determine the appropriate set for efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sets of beta offset values are configured for the UE, then the adaptability of resource allocation for UCI transmission is improved, but the complexity of specifying and selecting the appropriate set increases
Solution Approach 1:
The patent introduces a set designation field as an intermediary element that mediates between the multiple configured beta offset sets and the resource allocation process. This field, included in downlink control information, serves as a selector that points to the appropriate beta offset set, thereby simplifying the UE's task from managing multiple sets to simply reading the designation field and applying the indicated set, thus resolving the contradiction between adaptability and complexity
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple sets of beta offset values and their corresponding set designation fields in advance through higher layer signaling. This preparation allows the UE to efficiently select the appropriate resource allocation parameters without performing complex real-time calculations, as the correct set is already identified and designated before the actual UCI transmission occurs
2Productivity
If an appropriate specification method for beta offset sets is not used, then the simplicity of the system is maintained, but the communication throughput and spectral efficiency deteriorate
Solution Approach 1:
The set designation field acts as an intermediary that bridges the gap between simple system operation and optimized throughput. By including this compact field in the downlink control information, the system achieves high communication throughput through appropriate resource allocation while maintaining simplicity in UE implementation, as the UE only needs to read and apply the designated set rather than perform complex optimization algorithms

AI summary
A user terminal according to one aspect of the present disclosure includes a transmitting section that transmits uplink data and uplink control information on an uplink shared channel, and a control section that specifies one set among a plurality of sets of beta offset values, and controls an amount of resources for transmission of the uplink control information on the uplink shared channel, based on one of the beta offset values selected from the one set. According to one aspect of the present disclosure, reduction of communication throughput and so on can be prevented in UCI on PUSCH.
