Resource Indication Value Encoding for Non-Contiguous Block Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resource block allocation methods in wireless communications, particularly in 5G networks, face inefficiencies when dealing with non-contiguous sequences of resource blocks, requiring additional overhead bits and complex protocols to determine starting locations and lengths, which limits allocation flexibility.
Innovation Solution
A method that determines a single resource indication value using a predefined equation with two parameters, allowing for efficient allocation of non-contiguous resource block sequences by discretizing starting locations and lengths based on a resolution factor, enabling flexible allocation without extra overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional DCI formats are used to allocate non-contiguous RB sequences, then allocation flexibility is improved, but overhead bits increase and system complexity increases
Solution Approach 1:
The patent merges the indication of starting RB location and RB sequence length into a single RIV parameter. Instead of using separate fields for starting location and length, the invention combines them into one compact indicator that the UE can decode efficiently, thereby reducing overhead bits while maintaining allocation flexibility.
Solution Approach 2:
The patent changes the parameter representation by introducing a resolution factor that discretizes the RB sequence length. This allows the RIV to encode both starting location and length information in a compressed form, reducing the number of bits required while supporting non-contiguous allocations.
2Adaptability or versatility
If conventional DCI formats are used to allocate non-contiguous RB sequences, then allocation flexibility is improved, but device complexity increases
Solution Approach 1:
The patent enables the UE to self-determine the RB allocation by decoding the RIV and using the resolution factor to interpret the starting location and length. This eliminates the need for additional protocols between BS and UE to clarify the allocation, reducing protocol complexity while maintaining flexibility.
Solution Approach 2:
The patent performs preliminary discretization of the RB sequence length based on the resolution factor before encoding into RIV. This pre-processing step simplifies the subsequent decoding process at the UE, reducing the computational complexity and protocol overhead required during actual allocation.
3Adaptability or versatility
If RIV is used to indicate multiple combinations of RB sequence length and starting location, then allocation flexibility is improved, but reliability decreases
Solution Approach 1:
The patent applies different interpretation rules for RIV based on the specific combination of starting location and sequence length. By localizing the interpretation logic to specific RIV ranges and patterns, the system maintains unambiguous determination while supporting multiple allocation configurations, thus preserving both flexibility and reliability.
