Resource Block Allocation Using RIV for Non-Contiguous 5G Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource block allocation formats in wireless communications, particularly in 5G networks, are inefficient for non-contiguous sequences, leading to unnecessary bit overhead and waste due to the requirement for contiguous increases or decreases in starting resource block locations and lengths, which is not suitable for emerging communication demands like IoT and mMTC.
Innovation Solution
A method for allocating resource blocks using a resource indication value (RIV) based on conditional equations that allow for both contiguous and non-contiguous sequences, optimizing the number of bits required by determining the RIV based on the sequence's starting identifier and length, thereby reducing overhead.

1Productivity
If resource blocks are allocated based on proportional fairness using per-user channel quality indicators, then system throughput is improved, but the complexity of selecting and managing multiple channel quality indicators increases
Solution Approach 1:
The patent segments the channel quality assessment into multiple indicators (CQI1, CQI2, CQI3) corresponding to different resource block groups. Each CQI reflects channel quality for specific RBGs, allowing the system to select appropriate indicators based on allocation patterns rather than managing all possible combinations, thus reducing complexity while maintaining throughput optimization
Solution Approach 2:
The patent pre-calculates and stores multiple channel quality indicators for different resource block group configurations before actual resource allocation. This preliminary computation allows the base station to quickly select the most relevant CQI during scheduling based on the intended RBG allocation pattern, avoiding complex real-time calculations and reducing operational complexity
2Device complexity
If a single channel quality indicator is used for all resource blocks, then the complexity of channel quality management is reduced, but the accuracy of resource block allocation deteriorates
Solution Approach 1:
The patent applies local quality by calculating separate channel quality indicators (CQI1, CQI2, CQI3) for different resource block group configurations. Each CQI reflects the specific channel conditions for its corresponding RBGs, allowing accurate, localized quality assessment rather than a single global indicator, thereby improving allocation accuracy without significantly increasing management complexity
Solution Approach 2:
The patent implements dynamic selection of channel quality indicators based on the actual resource block group allocation pattern. The system adapts which CQI to use for each scheduling decision, selecting the most relevant indicator dynamically rather than using a static single indicator or always using all indicators, thus balancing accuracy and complexity

AI summary
A system and method for allocating network resources are disclosed herein. In one embodiment, the system and method are configured to perform: determining a resource indication value based on a combination of at least two of a first parameter, a second, and a third parameter, the resource indication value indicative of respective identifiers of a sequence of resource blocks to be allocated to a communication node, wherein the resource indication value is determined by a predefined relationship between the combination of the at least two of the first, second, and third parameters; and transmitting the resource indication value to the communication node.
