Terminal UCI Multiplexing Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems face challenges in appropriately determining resources for the Physical Uplink Control Channel (PUCCH) when multiple Uplink Control Information (UCI) with different priorities are multiplexed, leading to inefficiencies in resource allocation.
Innovation Solution
A terminal and radio communication system that includes a control unit capable of multiplexing UCI with different priorities in the PUCCH, determining resources based on whether the first UCI is associated with the first downlink control information, allowing for dynamic or semi-static resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple UCIs with different priorities are multiplexed in PUCCH, then the quantity of information transmitted is improved, but the resource allocation complexity increases
Solution Approach 1:
The patent segments the PUCCH resource allocation process by introducing separate determination methods for different UCI priorities. When multiple UCIs with different priorities are multiplexed, the resource allocation is divided into priority-based segments, where each priority level can have its own resource determination rules, thus managing the complexity of handling multiple UCIs simultaneously
Solution Approach 2:
The patent implements dynamic resource determination based on the association between downlink control information and uplink control information. The resource allocation is not fixed but adapts dynamically based on whether the first UCI is associated with downlink control information, allowing the system to flexibly handle different multiplexing scenarios
2Adaptability or versatility
If dynamic resource allocation is used for multiplexed UCIs, then the adaptability is improved, but the processing complexity increases
Solution Approach 1:
The patent employs dynamic resource determination where the PUCCH resource is selected based on real-time association conditions between downlink and uplink control information. This dynamic approach allows the system to adapt to different multiplexing scenarios while providing clear decision rules that manage processing complexity
Solution Approach 2:
The system enables self-service resource allocation by using the association relationship between downlink control information and uplink control information as the decision criterion. The terminal autonomously determines the appropriate PUCCH resource based on predefined rules, reducing the need for complex external coordination

AI summary
A terminal is disclosed including a control unit that is capable of multiplexing a first uplink control information of a first priority and a second uplink control information of a second priority in an uplink control channel; and a communication unit that transmits an uplink signal via the uplink control channel, wherein the control unit determines a resource of the uplink control channel based on whether the first uplink control information is associated with the first uplink control information.
