Solution Overview

Problem

Current wireless communication systems face challenges in efficient resource allocation, particularly in scenarios where the bandwidth of processed frequency resources by user equipment (UE) is smaller than the allocated bandwidth part, leading to issues with interleaved mapping and resource allocation efficiency.

Innovation Solution

The solution involves disabling or prohibiting interleaved mapping when the UE's processed bandwidth is smaller than the allocated bandwidth part, and instead, using a subset of resources within the bandwidth part for mapping, as indicated by the base station, to ensure efficient resource allocation without exceeding the UE's processing capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If interleaved mapping is used for resource allocation in a bandwidth part, then resource allocation flexibility is improved, but processing complexity and errors increase when UE bandwidth is smaller than allocated bandwidth part

Engineering Contradiction:
Improveresource allocation flexibilityVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes the mapping parameter from interleaved mapping to non-interleaved mapping based on the relationship between UE processing bandwidth and allocated bandwidth part. When UE bandwidth is smaller than the allocated bandwidth part, non-interleaved mapping is applied to reduce processing complexity and avoid errors, while maintaining resource allocation flexibility when UE bandwidth is sufficient.

Principle #35Parameter changes

2Reliability

If interleaved mapping is used for resource allocation, then resource distribution is improved, but allocation efficiency decreases when UE processing bandwidth is limited

Engineering Contradiction:
Improveresource allocation reliabilityVSAvoidresource allocation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent dynamically selects between interleaved and non-interleaved mapping based on real-time conditions (UE processing bandwidth vs. allocated bandwidth part). This dynamic adaptation ensures reliable resource allocation by avoiding interleaved mapping when UE processing capabilities are insufficient, while maintaining allocation efficiency through non-interleaved mapping in such scenarios.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If the base station allocates a full bandwidth part to UE, then resource allocation coverage is improved, but UE processing burden increases beyond its capabilities

Engineering Contradiction:
Improveallocated resource quantityVSAvoidUE processing ease
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent segments the bandwidth part into manageable portions by applying non-interleaved mapping when UE processing bandwidth is smaller than the allocated bandwidth part. This segmentation approach allows the UE to process resources in a more manageable manner, reducing processing burden while still receiving adequate resource allocation coverage.

Inventive Principle:
Principle #1Segmentation

AI summary

A method and apparatus are disclosed. In an example from the perspective of a base station, the base station transmits a configuration of a bandwidth part to a User Equipment (UE). The base station determines a subset of frequency resources within the bandwidth part. The base station transmits, to the UE, an indication of one or more allocated resources, within the subset of frequency resources, for a transmission. The base station does not enable interleaved mapping for the transmission.
