Solution Overview
Problem
Existing wireless communication systems face limitations in communication flexibility and efficiency, particularly in 3GPP LTE and LTE-Advanced networks, which affect the performance of user equipment and base stations.
Innovation Solution
Implementing enhanced methods for uplink and downlink transmissions in user equipment and base stations, including improved scheduling and resource allocation techniques, such as enhanced Physical Downlink Control Channel (PDCCH) and Physical Uplink Control Channel (PUCCH) management, to optimize communication efficiency and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing communication structures are used in LTE and LTE-Advanced networks, then device portability and convenience are maintained, but communication flexibility and efficiency are limited
Solution Approach 1:
The patent implements dynamic resource allocation where the base station can flexibly assign uplink control information to different physical channels (PUCCH or PUSCH) based on real-time scheduling decisions. This dynamic approach allows the system to adapt communication structures to varying traffic conditions, resolving the contradiction between communication flexibility and efficiency by making the system adaptable rather than static
Solution Approach 2:
The patent enables uplink control information to be transmitted through multiple possible channels (both PUCCH and PUSCH), creating a multi-functional system. The same control information can be routed through different channels depending on scheduling decisions, thereby achieving both flexibility (multiple path options) and efficiency (optimal channel selection) simultaneously
2Productivity
If communication capacity and speed are improved, then consumer expectations for reliable service are met, but system complexity increases
Solution Approach 1:
The patent changes the scheduling parameter from fixed to dynamic, allowing the base station to adjust resource allocation based on traffic conditions. This parameter change enables improved communication capacity through optimized resource usage while managing system complexity by using intelligent scheduling algorithms rather than requiring complex hardware modifications
3Speed
If resource allocation is optimized, then communication speed increases, but scheduling complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the base station autonomously makes scheduling decisions to determine whether uplink control information should be transmitted on PUCCH or PUSCH based on current resource availability and traffic conditions. This self-service scheduling approach improves communication speed through optimized resource allocation while managing complexity by using decision algorithms rather than manual configuration

AI summary
A user equipment (UE) is described. The UE includes a higher layer processor configured to acquire a first radio resource control (RRC) configuration including first information for indicating a control resource set (CORESET), to acquire second RRC configuration including second information for indicating one or more search space sets, and to acquire third RRC configuration including third information for indicating a resource set for physical downlink shared channel (PDSCH) rate matching. The UE also includes physical downlink control channel (PDCCH) receiving circuitry configured to monitor a PDCCH. The UE also includes PDSCH receiving circuitry configured to receive the PDSCH, upon a detection of the PDCCH.
