Solution Overview

Problem

Existing wireless communication systems fail to determine the number of coded modulation symbols per layer when uplink control information (UCI) with different priorities is multiplexed on a physical uplink shared channel (PUSCH).

Innovation Solution

A method and apparatus for determining the number of coded modulation symbols per layer by obtaining control factors to limit resource occupancy, and separately calculating the number of symbols for UCI with different priorities multiplexed on a PUSCH, using specific formulas based on priority and UCI type.

1Productivity

If UCI with different priorities is multiplexed on a PUSCH, then communication efficiency is improved, but the ability to determine the number of coded modulation symbols per layer deteriorates

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent segments the determination process of coded modulation symbols by separating UCI with different priorities. It introduces separate control factors (first control factor for high-priority UCI, second control factor for low-priority UCI) and separate calculation formulas for different priority levels, enabling independent resource allocation and symbol determination for each priority class while maintaining overall multiplexing efficiency.

2Adaptability or versatility

If control factors are introduced to limit resource occupancy, then resource management is improved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by introducing different control factors for different priority levels of UCI. The first control factor specifically limits resource occupancy for high-priority UCI, while the second control factor does the same for low-priority UCI. This localized resource management approach allows flexible adaptation to different service requirements without requiring a complete redesign of the resource allocation system.

AI summary

A method and an apparatus for determining the number of coded modulation symbols, and a communications device are provided. The method includes: obtaining, by a communications device, at least one control factor, where the control factor is used to limit a resource occupied when UCI is multiplexed on a PUSCH; determining first target UCI and second target UCI multiplexed on a target PUSCH for transmission, where a priority of the first target UCI is a first priority, a priority of the second target UCI is a second priority, and the first priority is lower than the second priority; and separately determining, according to a target control factor, the number of coded modulation symbols per layer in a case that the first target UCI and the second target UCI are multiplexed on the target PUSCH.
