Solution Overview

Problem

The existing LTE systems face a challenge in efficiently allocating uplink frequency domain resources due to insufficient total bits for indicating single-cluster resource location allocation information within certain system bandwidths during uplink transmission, particularly when multiple ports are used.

Innovation Solution

The method involves determining the number of total bits for multi-port frequency domain resource location allocation information based on system bandwidth and aligning the bits of single-cluster or multiple-cluster uplink frequency domain resource location allocation information with the Least Bit Status (LBS) or Most Bit Status (MBS) bit within the total bits, ensuring sufficient bit allocation for accurate resource indication.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the existing multi-port frequency domain resource location allocation information bit allocation method is used, then the indication capability for multiple clusters is supported, but the total bits are insufficient to indicate single-cluster uplink resource location allocation information within certain system bandwidths

Engineering Contradiction:
Improveindication capability for multiple clustersVSAvoidtotal bits for resource location allocation
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies dynamic bit allocation by determining the number of bits for frequency domain resource location allocation information based on the actual system bandwidth. The bit allocation is no longer fixed but dynamically adjusted according to the specific bandwidth configuration, allowing the system to allocate sufficient bits for single-cluster indication while maintaining compatibility with multi-cluster scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of bit allocation by introducing a determination mechanism that calculates the required number of bits based on system bandwidth. This parameter change transforms the fixed bit allocation into a variable one that adapts to different bandwidth scenarios, ensuring sufficient representation capacity for single-cluster resource location information.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the bit allocation is increased to accommodate single-cluster resource location information, then the indication completeness is improved, but the complexity of bit allocation determination increases

Engineering Contradiction:
Improveindication completeness of resource locationVSAvoidcomplexity of bit allocation determination
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent simplifies the complexity issue by establishing a clear parameter-based determination method where the number of bits is directly derived from system bandwidth. This systematic approach replaces complex ad-hoc allocation with a standardized parameter change mechanism that is easier to implement and manage.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system performs self-service by automatically determining the appropriate bit allocation based on the configured system bandwidth without requiring external intervention or complex manual configuration. The determination mechanism inherently adapts to the system's actual bandwidth configuration, ensuring both completeness and simplicity.

Inventive Principle:
Principle #25Self-service

3Reliability

If single-cluster resource location allocation is indicated with sufficient bits, then the uplink transmission reliability is improved, but the resource overhead increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent achieves the balance between reliability and overhead through parameter-based dynamic allocation. The number of bits is precisely determined according to system bandwidth, providing sufficient representation for single-cluster resource locations while avoiding excessive allocation. This parameter-driven approach ensures optimal resource utilization.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial action by allocating bits precisely according to the actual bandwidth requirements rather than providing a fixed excessive allocation. The bit allocation is tailored to the specific system configuration, providing just enough capacity for reliable single-cluster indication without unnecessary overhead.

Inventive Principle:
Principle #16Partial or excessive action
