NR PUSCH and NR PUCCH Multiplexing in Control Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently multiplexing data and control information, particularly in high-data-rate scenarios such as those supported by New Radio (NR) networks, where existing methods struggle to manage the allocation of time and frequency resources effectively.
Innovation Solution
The proposed solution involves a method for the User Equipment (UE) to decode downlink control information (DCI) that indicates an allocation for NR physical uplink shared channel (NR PUSCH) transmissions, allowing for flexible allocation of physical resource blocks (PRBs) across data and control regions within a slot, enabling NR PUSCH and NR PUCCH multiplexing in the same symbol periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time resources and frequency resources are allocated for multiplexing of data and control information in a frame, then resource utilization improves, but device complexity increases due to challenging operations at high data rates
Solution Approach 1:
The slot is divided into a data region and a control region, with the data region containing one or more symbol periods for NR PUSCH transmission and the control region containing one or more symbol periods for NR PUCCH transmission. This segmentation allows independent resource allocation and simplifies the multiplexing operations by separating data and control channels into distinct regions while still enabling efficient resource utilization through flexible allocation within each region.
2Reliability
If NR PUSCH transmission is restricted to data region only, then control channel reliability is maintained, but data rate is limited and cannot support high-speed NR applications
Solution Approach 1:
The invention extends NR PUSCH transmission from the traditional data region only into the control region dimension, allowing data transmission in both data region symbol periods and control region symbol periods. This dimensional expansion of transmission resources significantly increases the available bandwidth for data transmission while maintaining control channel reliability through dedicated control region allocation, thereby supporting high data rate NR applications.
3Adaptability or versatility
If flexible allocation of PRBs across data and control regions is implemented, then adaptability improves for high data rate scenarios, but difficulty of detecting and measuring resource allocation increases
Solution Approach 1:
By segmenting the slot into distinct data and control regions with clearly defined symbol period allocations, the invention provides a structured framework for flexible PRB allocation. The data region is configured to include one or more symbol periods and the control region includes one or more symbol periods, creating clear boundaries that simplify resource allocation detection and measurement while maintaining high adaptability for different data rate scenarios.

AI summary
Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication are generally described herein. The UE may receive downlink control information (DCI) that indicates an allocation for a new radio (NR) physical uplink shared channel (NR PUSCH) transmission, by the UE, in a channel of multiple physical resource blocks (PRBs) in a slot that comprises: a predetermined data region, and a predetermined control region reserved for NR physical uplink control channel (NR PUCCH) transmissions. The DCI may be configurable to indicate whether the allocation includes one or more of the PRBs in the control region. The allocation may include one or more of the PRBs in one or more symbol periods in the data region and may be configurable to include one or more of the PRBs in one or more symbol periods in the control region.
