Physical Uplink Channel Prioritization for Overlap Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in ensuring secure and efficient handling of physical uplink channels, particularly in the presence of intercepting communication devices, which can compromise the security and integrity of data transmission.
Innovation Solution
The proposed solution involves a communication manager in the user equipment (UE) that identifies security levels for overlapping physical uplink channels and transmits them based on these levels, enhancing security and prioritization of channels according to their security requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink channels are multiplexed on the same time-frequency resources, then resource utilization efficiency is improved, but security risk increases due to potential eavesdropping on confidential information
Solution Approach 1:
The uplink channel is segmented into multiple layers (physical layer, MAC layer, RLC layer, PDCP layer) with different security protection mechanisms applied to each layer, allowing confidential information to be separated from non-confidential information and protected accordingly
Solution Approach 2:
Different security protection measures are applied to different parts of the channel based on their security requirements - confidential information receives enhanced protection through dedicated physical channels or stronger encryption, while non-confidential information uses standard multiplexing
2Power
If physical channel resources are allocated for uplink channels, then transmission capability is improved, but resource waste occurs when channels are not fully utilized
Solution Approach 1:
Multiple uplink channels (PUCCH, PUSCH, SRS) are merged and multiplexed on the same time-frequency resources when possible, allowing the system to achieve full transmission capability while utilizing resources more efficiently by combining channel functions
Solution Approach 2:
The channel allocation and multiplexing configuration is made dynamic, allowing the system to adjust resource allocation based on real-time traffic conditions and channel state, ensuring transmission capability is maintained while minimizing resource waste during low-utilization periods

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a set of security levels for a set of physical uplink channels, wherein the set of physical uplink channels are overlapping in time. The UE may transmit one or more of the set of physical uplink channels based at least in part on the set of security levels for the set of physical uplink channels. Numerous other aspects are described.
