Compact UCI Mapping on PUSCH for Faster Uplink Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face inefficiencies in processing uplink control information (UCI) due to uncertainties in transmission parameters, leading to increased processing times, resource consumption, and higher rates of dropped or delayed communications.
Innovation Solution
A method and apparatus for a user equipment (UE) to determine and transmit UCI that identifies transmission parameters for a physical uplink shared channel (PUSCH) communication, enabling efficient processing and reducing the need for iterative parameter guessing by the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UCI transmission parameters are not clearly defined for PUSCH communications, then the system maintains flexibility in resource allocation, but processing times increase and communication reliability decreases
Solution Approach 1:
The patent applies preliminary action by pre-defining UCI transmission parameters (such as modulation scheme, coding rate, resource allocation) for PUSCH communications before actual transmission occurs. This allows the base station to prepare demodulation and decoding configurations in advance, reducing processing time during actual communication while maintaining reliable transmission through standardized parameter sets.
2Productivity
If UCI transmission parameters are clearly defined for PUSCH communications, then processing efficiency improves and communication reliability increases, but system flexibility and adaptability decrease
Solution Approach 1:
The patent applies parameter changes by defining specific UCI transmission parameters (modulation order, coding rate, resource block allocation) that can be adjusted based on channel conditions and traffic requirements. This allows the system to maintain processing efficiency through standardized parameter definitions while preserving adaptability by enabling dynamic selection from predefined parameter sets according to actual communication needs.
3Reliability
If UCI is transmitted without clear parameter definitions, then resource allocation remains flexible, but the need for retransmissions increases
Solution Approach 1:
The patent applies feedback by incorporating acknowledgment mechanisms where the base station confirms successful reception and decoding of UCI transmissions. With clearly defined parameters, the base station can reliably decode UCI and provide feedback to the UE, reducing retransmissions. The feedback loop ensures communication success while minimizing redundant transmissions through proper parameter configuration.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit a compact uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU). The UE may transmit the UCI in the PRU based at least in part on a semi-static payload construction and resource mapping rule. Numerous other aspects are provided.
