Uplink Transport Block Transmission Without Padding Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in utilizing uplink resources for multiple transport blocks, leading to increased power consumption and latency due to the need for padding bits to fill allocated resources, especially in cases where not all resources are utilized.
Innovation Solution
The solution involves transmitting multiple transport blocks via different transmission layers, allowing for skipping unused resources and indicating the unused portions, thereby optimizing resource usage and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If padding bits are added to fill allocated uplink resources for multiple transport blocks, then resource allocation completeness is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent extracts and removes the unnecessary padding bits from the uplink transmission. The base station is configured to indicate which transport blocks should be padded and which should not, allowing the system to eliminate redundant padding transmissions and reduce power consumption while maintaining reliable resource allocation for actual data.
Solution Approach 2:
The patent changes the padding parameter configuration by introducing base station-controlled indication messages that dynamically adjust padding requirements. The base station can set different padding configurations for different transport blocks based on actual data availability, transforming a static full-padding approach into a dynamic selective-padding approach.
2Reliability
If padding bits are added to fill allocated uplink resources, then resource utilization is improved, but latency increases
Solution Approach 1:
The patent removes unnecessary padding bits from uplink transmissions by enabling the base station to indicate which transport blocks require padding and which do not. This extraction of redundant padding data reduces the total transmission time and latency while maintaining proper resource allocation for actual payload data.
3Reliability
If unused uplink resources are transmitted with padding, then resource allocation efficiency is improved, but spectral efficiency decreases
Solution Approach 1:
The patent extracts and eliminates unnecessary padding transmissions by enabling the base station to indicate which transport blocks should not be padded. This removes wasteful spectral usage from the system, improving spectral efficiency by ensuring that only necessary data occupies uplink resources.
Solution Approach 2:
The patent changes the transmission parameter configuration by introducing dynamic padding control indicators from the base station. These indicators modify the padding parameters for different transport blocks based on actual data conditions, optimizing spectral usage by preventing padding of empty or partially-filled transport blocks.

AI summary
Methods, systems, and devices for wireless communications are described that provide for transmitting two or more transport blocks in an uplink transmission, in which a transmitting device may skip transmissions in some portion of a set of allocated resources for the transport blocks. Uplink data may be encoded to be transmitted via the multiple transport blocks, where a first transport block may have first transport block size that is different than a second transport block size of a second transport block. The transport block sizes may be less than the size of the set of allocated resources, and the transport blocks may be transmitted via the different transmission layers, and a portion of the allocated resources may be unused. The transmitting device may provide an indication of the unused resources for use in decoding the transport blocks.
