PUSCH Signaling Bit Control for Transform Precoder Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing the number of bits in signaling related to transform precoders, leading to ambiguity, increased overhead, and reduced scheduling flexibility, particularly in scenarios like eMBB, URLLC, and MBS.
Innovation Solution
A method and apparatus that manage the number of bits in signaling by enabling or disabling transform precoders on cells within a cell set, ensuring that when all cells have enabled precoders, the number of bits is zero, and when any cell is disabled, the number of bits is one, thereby optimizing scheduling flexibility and reducing ambiguity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of bits in the first domain of the first signaling is increased to provide scheduling flexibility, then scheduling flexibility is improved, but signaling overhead increases
Solution Approach 1:
The patent applies dynamics by making the number of bits in the first domain configurable based on the transform precoder status. When transform precoder is disabled on any cell, the field uses 1 bit to indicate the status; when transform precoder is enabled on all cells, the field uses 0 bits. This dynamic adaptation resolves the contradiction by adjusting signaling overhead according to actual scheduling flexibility requirements.
Solution Approach 2:
The patent changes the parameter of the first domain's bit length based on the transform precoder configuration state. By setting the number of bits to 0 or 1 according to whether transform precoder is enabled or disabled, the system optimizes the balance between scheduling flexibility and signaling overhead, directly resolving the technical contradiction.
2Quantity of substance
If the number of bits in the first domain is set to a fixed value, then signaling overhead is reduced, but ambiguity in understanding the first domain increases
Solution Approach 1:
The patent uses feedback mechanisms where the base station determines the transform precoder status and configures the appropriate number of bits accordingly. This feedback loop ensures that the signaling overhead is minimized while the receiving end can correctly interpret the first domain based on the configured bit length, eliminating ambiguity.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the number of bits in the first domain based on the transform precoder status before transmission. This preliminary configuration ensures that both transmitting and receiving ends have consistent understanding of the signaling format, preventing ambiguity while maintaining low overhead.
3Quantity of substance
If transform precoder is disabled on cells to reduce signaling overhead, then signaling overhead is reduced, but demodulation performance deteriorates
Solution Approach 1:
The patent dynamically adjusts the transform precoder configuration based on channel conditions and service requirements. When channel conditions are good and overhead needs reduction, transform precoder can be disabled with 0 bits. When demodulation performance needs improvement, transform precoder is enabled with 1 bit indication, thus dynamically balancing overhead and performance.
Solution Approach 2:
The patent changes the transform precoder parameter based on system state. By configuring whether transform precoder is enabled or disabled according to channel quality and service type, the system optimizes the tradeoff between signaling overhead and demodulation performance, resolving the contradiction between these two parameters.
