Uplink Control Multiplexing for Skipped Wireless Transmissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing uplink transmissions, particularly in scenarios where data is not available for transmission, leading to inefficiencies in resource utilization and potential interference.
Innovation Solution
Implementing uplink skipping and uplink control information multiplexing techniques, where a subset of uplink transmissions includes uplink control information multiplexed from the remainder of the transmissions when data is not available, optimizing resource allocation and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uplink transmissions are performed continuously even when data is not available, then resource allocation is simplified, but resource utilization efficiency deteriorates and interference increases
Solution Approach 1:
The system dynamically adjusts uplink transmission behavior based on data availability. When data is available, normal transmissions occur; when data is not available, transmissions are skipped. This dynamic adaptation resolves the contradiction by making resource allocation simple only when necessary while maximizing resource utilization when data is present.
Solution Approach 2:
The transmission parameters are changed based on data availability conditions. The system transitions between different transmission states (transmit vs. skip) depending on whether data is available, thereby optimizing resource utilization without permanently complicating the resource allocation structure.
2Reliability
If uplink transmissions are performed continuously even when data is not available, then transmission reliability is maintained, but interference increases and resource waste occurs
Solution Approach 1:
The harmful element (unnecessary transmission when no data is available) is extracted and removed from the system. By skipping transmissions when data is not available, the system eliminates source interference while maintaining reliability for actual data transmissions.
3Productivity
If uplink control information is multiplexed from transmissions where data is not available, then resource utilization is improved, but system complexity increases
Solution Approach 1:
Uplink control information from skipped transmissions is merged with subsequent transmissions that have data available. This combining approach improves resource utilization by avoiding duplicate control information transmission while managing complexity through standardized multiplexing procedures.
Solution Approach 2:
The uplink transmission mechanism serves multiple functions: it transmits both data and control information, and it adapts its behavior based on data availability. This multi-functionality allows the system to improve resource utilization without requiring separate dedicated mechanisms for control information.
4Productivity
If uplink transmissions are skipped when data is not available, then resource utilization improves, but transmission reliability may deteriorate
Solution Approach 1:
The system uses feedback mechanisms to ensure that skipped transmissions are properly accounted for. Control information from skipped transmissions is fed forward to subsequent transmissions, ensuring that no control information is lost while still achieving resource utilization improvements through skipping.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information identifying a set of uplink resources for a set of uplink transmissions. The UE may transmit a subset of the set of uplink transmissions, wherein the subset of the set of uplink transmissions includes uplink control information multiplexed from a remainder of the set of uplink transmissions corresponding to one or more instances in which data is not available for transmission. Numerous other aspects are described.
