Terminal Uplink Multiplexing Groups for Simpler Collision Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The allocation of uplink control and shared channels in a slot complicates signal collision control, making terminal implementation difficult in wireless communication systems.
Innovation Solution
A terminal is equipped with a reception unit to identify multiplexing groups, a control unit to perform multiplexing within these groups, and a transmission unit to send the multiplexed information to the base station, simplifying the transmission process.

Engineering Contradiction Analysis
1Adaptability or versatility
If uplink control channel and uplink shared channel are allocated freely in a slot, then resource utilization and flexibility are improved, but control complexity and terminal implementation difficulty increase
Solution Approach 1:
The patent divides uplink channels into separate multiplexing groups (first multiplexing group for PUCCH, second multiplexing group for PUSCH) with distinct multiplexing rules. This segmentation allows flexible resource allocation while simplifying terminal processing by providing clear, separate handling procedures for different channel types, thereby resolving the contradiction between allocation flexibility and implementation complexity.
2Productivity
If free allocation of PUCCH and PUSCH is implemented, then system capacity and data transmission rate are improved, but signal collision control complexity increases
Solution Approach 1:
By segmenting channels into different multiplexing groups with dedicated rules, the patent enables high system capacity through flexible allocation while simplifying collision control. The first multiplexing group handles PUCCH with specific multiplexing rules, and the second multiplexing group handles PUSCH with different rules, preventing complex collision scenarios while maintaining high productivity.
Solution Approach 2:
The patent establishes multiplexing rules in advance for different channel groups before actual transmission occurs. This preliminary configuration of multiplexing behavior allows the system to achieve high data transmission rates while avoiding complex real-time collision control, as terminals can pre-process and prepare transmissions according to predetermined rules.

AI summary
A terminal includes: a reception unit configured to receive information indicating which multiplexing group is to be a multiplexing destination of uplink information from a base station; a control unit configured to perform multiplexing of the uplink information for each multiplexing group; and a transmission unit configured to transmit the multiplexed uplink information to the base station.
