Uplink Signal Processing Mode for Overlapping Data and Control Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR technologies face inefficiencies in transmitting uplink signals, particularly in scenarios where uplink data and control information have overlapping transmission times, leading to suboptimal resource allocation and reliability issues due to static configuration of parameters like βoffsetHARQ-ACK and α, which fail to dynamically adjust to varying reliability and latency requirements of different use cases.
Innovation Solution
A terminal and communication method that dynamically determine a processing mode for uplink data and control information based on requirements, allowing for flexible resource allocation by adjusting parameters such as βoffsetHARQ-ACK and α, ensuring appropriate transmission of uplink signals according to the specific reliability and latency needs of different use cases, such as eMBB and URLLC.

Engineering Contradiction Analysis
1Productivity
If transmission of uplink data channel and uplink control channel overlap in time, then resource utilization efficiency improves, but transmission reliability deteriorates due to static parameter configuration
Solution Approach 1:
The patent applies dynamics by making the processing mode configurable based on different scenarios. The terminal can be configured to select from multiple processing modes (drop one of the channels, multiplex control information on data channel, or puncture data channel) depending on the specific transmission scenario, transforming a static system into a dynamic one that adapts to different reliability and efficiency requirements
Solution Approach 2:
The patent changes parameters by introducing configurable processing mode parameters that determine how overlapping channels are handled. The network can configure different processing modes via RRC signaling or DCI, allowing the system to adjust the processing behavior (which channel to drop, how to multiplex, puncture pattern) based on traffic type, QoS requirements, and channel conditions
2Device complexity
If processing mode is statically configured, then device complexity reduces, but adaptability to different use cases deteriorates
Solution Approach 1:
The patent implements dynamics by enabling configurable processing modes that can be adjusted based on different use cases such as eMBB and URLLC. The terminal receives configuration from the network via RRC signaling or DCI and dynamically selects the appropriate processing mode, allowing the system to adapt to varying reliability and latency requirements without permanently increasing device complexity
Solution Approach 2:
The patent applies universality by designing a processing framework that handles multiple different scenarios through a unified configurable mechanism. The same terminal hardware and base processing logic can serve multiple functions by selecting different processing modes based on the configured parameters, making the system versatile across different 5G use cases without requiring separate dedicated processing paths

AI summary
Provided is a terminal that can appropriately transmit an uplink signal. In a terminal (200), a control unit (211) determines a processing mode with respect to uplink data and uplink control information according to a requirement for at least one of uplink data and uplink control information when transmission of an uplink data channel that includes the uplink data and transmission of an uplink control channel that includes the uplink control information temporally overlap. A transmission unit (218) transmits the at least one of the uplink data and the uplink control information on the basis of the determined processing mode.
