Polar Subblock Allocation Using a Universal Reliability Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face increased complexity and memory consumption due to specifying different reliability sequences for various modulation orders in polar coding, which does not scale with the quantity of supported modulation orders.
Innovation Solution
A wireless communication device identifies an allocation of information bits among polar channel subblocks using a reliability sequence associated with multiple modulation orders and a subblock allocation sequence associated with a single modulation order, reducing the need for storing multiple reliability sequences by using a single subblock allocation sequence.

Engineering Contradiction Analysis
1Measurement precision
If different reliability sequences are specified for various modulation orders, then the accuracy of polar coding is improved, but the device complexity and memory consumption increase
Solution Approach 1:
The patent applies universality by using a single reliability sequence that serves multiple modulation orders (QPSK, 16QAM, 64QAM, 256QAM) simultaneously. The base station and user equipment store and use only one reliability sequence regardless of which modulation order is active, making the system universal across different modulation schemes while avoiding the need for multiple separate reliability sequences.
Solution Approach 2:
The patent changes the parameter approach by transitioning from multiple modulation-specific reliability sequences to a single universal reliability sequence. This parameter change allows the system to maintain polar coding accuracy across different modulation orders without increasing memory storage requirements or system complexity.
