Solution Overview

Problem

Existing resource allocation signaling methods in broadband carrier systems often result in excessive overhead, particularly when using tree-based allocation schemes, leading to inefficient use of binary bits for denoting resource allocation cases, which can exceed the predetermined signaling overhead.

Innovation Solution

A method and apparatus for parsing continuous resource allocation signaling that adjusts the calculation of resource allocation signaling values to ensure the signaling overhead remains at ceil(log2(N*(N+1)/2) bits, using specific formulas and units to determine the number and location of allocated resource blocks, and converting binary signals to decimal for efficient parsing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a tree-based resource allocation method is used to reduce control signaling overhead, then the signaling overhead is reduced to ceil(log2(N*(N+1)/2)) bits, but the overhead may still exceed the predetermined signaling overhead in certain allocation cases

Engineering Contradiction:

Improvecontrol signaling overheadVSAvoidsignaling overhead precision

Core Design Contradiction:

Loss of informationVSManufacturing precision

Solution Approach 1:

The patent modifies the resource allocation signaling formula by changing the ceiling function argument from log2(N^2) to log2(N*(N+1)/2), which precisely matches the actual number of allocation cases. This parameter change ensures the signaling overhead exactly covers all possible allocations without exceeding predetermined limits.

2Adaptability or versatility

If conventional resource allocation signaling formulas are used, then all possible (O,P) combinations can be indicated, but the signaling overhead exceeds the actual number of allocation cases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent extracts and removes the redundant ceiling operation that causes overhead expansion. By changing ceil(log2(N^2)) to ceil(log2(N*(N+1)/2)), it extracts only the necessary bits to represent actual allocation cases, eliminating wasted signaling capacity while maintaining full allocation coverage.

AI summary

A method for generating continuous resource allocation signaling comprises: a sender determines a value of the total number of resource blocks NRB in a system according to the total resource number in the system and determines, according to the amount and location of the total resources occupied by the continuous resources allocated to the target user equipment, the number of continuous resource blocks allocated to the user equipment LCRBs and the value of the index number of the starting resource block RBstart in the continuous resource blocks allocated to the user equipment; a value RIV of resource allocation signaling of the user equipment is calculated, wherein the overhead of the resource allocation signaling is equal to ceil⁢log2⁢NRB⋅NRB+12 for numbers NRB of resource blocks in the system, including the case of NRB = 5; and the resource allocation signaling of the target user equipment is generated according to RIV and transmitted. An apparatus for generating continuous resource allocation signaling, and a method and an apparatus for parsing continuous resource allocation signaling, are also disclosed.
