Wireless Node RE Allocation for Reliable Control Block Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The relationship between the number of coded modulation symbols per layer used for transmitting a control information block and the RE resource block is not effectively managed when the control information block and a code block set are multiplexed for transmission within the same RE resource block, leading to inefficiencies in resource utilization and potential transmission reliability issues.
Innovation Solution
A method and apparatus for wireless communication that involves determining a target RE subset within an RE set for transmitting a code block set and a bit block, where the number of bits in the code block set and control information block jointly determine the number of coded modulation symbols per layer, ensuring these integers are not exceeded, and avoiding DMRS and PTRS occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control information block and code block set are multiplexed in the same RE resource block, then resource utilization efficiency is improved, but the relationship between coded modulation symbols and RE resources becomes complex and difficult to manage
Solution Approach 1:
The patent segments the RE set into a target RE subset specifically for control information block transmission. By dividing the RE resources and assigning specific subsets to different purposes (code block set vs. control information block), the patent simplifies the management of multiplexed transmissions while maintaining high resource utilization efficiency.
2Reliability
If more REs are allocated for control information block transmission, then transmission reliability is improved, but available resources for code block set transmission are reduced
Solution Approach 1:
The patent dynamically determines the number of coded modulation symbols per layer for control information block transmission based on available RE resources. The determination process considers the total REs in the target RE subset and adjusts the symbol allocation accordingly, enabling flexible resource distribution that maintains reliability while optimizing code block set transmission capacity.
3Quantity of substance
If the number of coded modulation symbols per layer is increased, then control information transmission capacity is improved, but the precision of resource allocation becomes more difficult to control
Solution Approach 1:
The patent employs a feedback mechanism where the number of coded modulation symbols per layer is determined based on the actual available RE resources in the target RE subset. The determination process uses the count of REs satisfying specific conditions as input to calculate the appropriate number of symbols, ensuring precise resource allocation that matches actual available capacity while maintaining transmission capacity.

AI summary
Disclosed in the present application is a method and an apparatus used in a wireless communication node. A first node receives first signaling, which is used to indicate a first RE set, and sends a first code block set and a first bit block in only a target RE subset within the first RE set. The first code block set is used to determine the target RE subset from the first RE set; a first control information block comprises the first bit block, and the number of bits comprised in the first control information block and the number of bits comprised in the first code block set are jointly used to determine a first integer; the number of all REs in the target RE subset that satisfy the first condition is used to determine a second integer; the first target integer is the number of coded modulation symbols per layer used for transmitting the first bit block in the target RE subset, and the first target integer is not greater than the first integer and not greater than the second integer.
