CG-PUSCH Resource Offsets for HARQ-ACK and CG-UCI Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new radio (NR) systems, the simultaneous transmission of physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) is not supported, leading to increased UE implementation complexity when uplink control information (UCI) is multiplexed on PUSCH, necessitating a method to determine the number of resource elements (REs) and locations for correct decoding.
Innovation Solution
A method to determine the number of resources occupied by joint coding of configured grant uplink control information (CG-UCI) and hybrid automatic repeat request acknowledgment (HARQ-ACK) on a configured grant physical uplink shared channel (CG-PUSCH) using offsets corresponding to CG-UCI and HARQ-ACK, allowing for correct decoding by network-side devices.

Engineering Contradiction Analysis
1Productivity
If UCI is multiplexed on PUSCH for transmission, then communication efficiency is improved, but UE implementation complexity increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the offset value (betaOffset) based on different service types and traffic conditions. The network can configure different offset parameters for different UCI types (HARQ-ACK, CSI, SR) and different PUSCH formats, allowing the system to adapt resource allocation parameters to specific scenarios, thereby improving communication efficiency while managing UE complexity through standardized parameter adjustment mechanisms.
Solution Approach 2:
The patent implements preliminary action by pre-configuring offset parameters through higher-layer signaling (RRC configuration) before actual UCI multiplexing occurs. The network pre-defines the resource element allocation offsets for different UCI types, so that when UCI needs to be multiplexed on PUSCH, the UE can directly apply these pre-configured parameters without complex real-time calculations, thus improving efficiency while controlling implementation complexity.
2Measurement precision
If the number of REs for UCI is increased, then decoding accuracy is improved, but available resources for data transmission are reduced
Solution Approach 1:
The patent uses parameter changes to dynamically adjust the betaOffset parameter that controls the ratio of REs allocated to UCI versus data. By changing this offset parameter based on channel conditions, UCI type, and traffic requirements, the system can optimize the balance between decoding accuracy and data transmission capacity without fixed resource allocations.
Solution Approach 2:
The patent implements dynamics by making the UCI resource allocation flexible and adaptive rather than static. The offset parameters can be dynamically adjusted through DCI signaling or pre-configured RRC parameters, allowing the system to adapt the number of REs allocated to UCI based on real-time conditions, thus optimizing both decoding accuracy and data transmission efficiency according to actual needs.

AI summary
A resource determining method, a resource determining apparatus, and a communications device. The resource determining method is applied to a terminal and includes: determining, based on an offset, the number of resources occupied by joint coding of configured grant uplink control information (CG-UCI) and hybrid automatic repeat request acknowledgment (HARQ-ACK) when the HARQ-ACK is multiplexed on a configured grant physical uplink shared channel (CG-PUSCH) for transmission, where the offset is determined by a first offset and/or a second offset, the first offset is an offset corresponding to the HARQ-ACK, and the second offset is an offset corresponding to the CG-UCI.
