UCI Multiplexing on PUSCH via Configurable Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently multiplexing Uplink Control Information (UCI) on the Physical Uplink Shared Channel (PUSCH) and other uplink physical layer channels, particularly in 5G New Radio (NR) networks, which affects transmission performance and resource allocation.
Innovation Solution
A method involving the transmission of a first information block and at least one transport block on a channel, where the number of transport blocks is determined by rounding up a product of a configurable parameter and resource size to the nearest integer, optimizing resource allocation and enhancing UCI transmission performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UCI is multiplexed on PUSCH with existing methods, then resource allocation can be performed, but transmission performance and resource utilization are insufficient
Solution Approach 1:
The patent determines the number of resource elements for UCI transmission by calculating the product of a configurable parameter and resource size, then rounding up to the nearest integer. This parameter-based approach allows flexible adjustment of resource allocation to optimize both transmission performance and resource utilization, rather than using fixed allocation methods.
Solution Approach 2:
The number of resource elements allocated for UCI is dynamically determined based on the number of transport blocks and configurable parameters, rather than being statically assigned. This dynamic allocation adapts to varying transmission conditions, improving both reliability and resource efficiency.
2Reliability
If the number of resource elements for UCI is fixed, then allocation is simple, but transmission performance of UCI and HARQ-ACK feedback is limited
Solution Approach 1:
The patent uses a configurable parameter multiplied by resource size, with the result rounded up to determine the number of resource elements. This parameter-driven approach enhances HARQ-ACK feedback performance while keeping the allocation mechanism relatively simple through standardized calculation rules.
Solution Approach 2:
The patent replaces complex heuristic allocation mechanisms with a systematic mathematical calculation approach (product of parameters, rounded up to nearest integer). This substitution provides both improved performance and computational simplicity.
3Reliability
If more resource elements are allocated to UCI, then transmission performance improves, but resource utilization ratio may decrease
Solution Approach 1:
The patent determines resource element allocation through configurable parameters that can be adjusted to balance CSI reporting performance and resource utilization. The configurable nature allows optimization based on specific network conditions and requirements.
Solution Approach 2:
The resource allocation is dynamically adjusted based on the number of transport blocks and configurable parameters, allowing the system to adaptively balance between ensuring sufficient resources for CSI reporting and maintaining high overall resource utilization.

AI summary
A first receiver receives a first signaling; and a first transmitter transmits a first information block and at least one TB on a first channel; herein, the first signaling is used for scheduling the first channel, and a first number is used for transmission of the first information block on the first channel, the first number being related to a number of TB(s) transmitted on the first channel and equal to a smallest one of multiple values; one of the multiple values depends on a result obtained by rounding up a product of a first parameter and a first resource size to a nearest integer, where the first parameter is configurable, and the first resource size is linear with at least one sub resource size, of which each sub resource size is a number of RE(s) allowed to be used for transmitting UCI in an OFDM symbol.
