Solution Overview

Problem

Current wireless cellular communication systems, such as LTE, lack the ability to configure reserved resources in the frequency domain, leading to inefficient operation for services like NB-IoT, which requires frequency-division multiplexing with LTE, resulting in cumbersome and inefficient designs.

Innovation Solution

The system allows for configurable resources on a PRB or RBG level in the frequency domain and an OFDM symbol, slot, or mini-slot level in the time domain, with additional signaling to control mobile device behavior regarding reserved resources, enabling adaptive control of rate matching and puncturing behavior around reserved resources.

Solution Approach 1:

The system segments the frequency domain resources into specific reserved resource blocks (RBs) or resource block groups (RBGs) for NB-IoT services. The base station configures reserved resources at granular levels (PRB or RBG level) in the frequency domain and OFDM symbol, slot, or mini-slot level in the time domain, allowing efficient frequency-division multiplexing while maintaining organized resource management

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements dynamic control of reserved resources through additional signaling mechanisms. The base station can dynamically adjust reserved resource configurations and control mobile device behavior regarding reserved resources, enabling adaptive rate matching and puncturing behavior around reserved resources based on network conditions and service requirements
