Dynamic Resource Multiplexing for Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in resource utilization due to semi-static resource partitioning between LTE enhanced Machine Type Communication (eMTC) and narrowband IoT (NB-IoT) and 5G NR, leading to suboptimal use of resources.
Innovation Solution
Implementing dynamic resource multiplexing by signaling uplink/downlink configurations that include both fixed and flexible resource allocations, allowing for flexible resource utilization between eMTC/NB-IoT and NR communications, enabling efficient use of resources and avoiding collisions with other signals.

Engineering Contradiction Analysis
1Productivity
If semi-static resource partitioning is used between eMTC/NB-IoT and 5G NR, then resource allocation is simplified and stable, but resource utilization efficiency deteriorates due to inability to dynamically adapt to changing traffic conditions
Solution Approach 1:
The patent introduces dynamic resource multiplexing where resources initially allocated for eMTC/NB-IoT can be dynamically reassigned to 5G NR when not in use. The base station transmits indication information to UEs about which resources are available for dynamic use, allowing the system to adapt resource allocation in real-time based on actual traffic conditions while maintaining a semi-static baseline configuration.
Solution Approach 2:
The patent creates a multi-functional resource allocation mechanism where the same physical resources can serve multiple purposes: primarily for eMTC/NB-IoT communication, and secondarily for 5G NR communication when eMTC/NB-IoT resources are idle. This universal resource pool approach allows flexible switching between different communication technologies without requiring completely separate dedicated resources for each.
2Productivity
If dedicated resources are allocated for eMTC/NB-IoT communication, then communication reliability is ensured, but bandwidth utilization deteriorates due to unused resources remaining idle
Solution Approach 1:
The patent implements a self-service resource allocation mechanism where the system automatically identifies and reallocates idle eMTC/NB-IoT resources to 5G NR without manual intervention. The base station monitors resource usage and dynamically adjusts allocations based on actual demand, allowing resources to serve themselves for their primary function while automatically becoming available for secondary use when idle.
Solution Approach 2:
The patent changes the operational parameters of resource allocation from fixed to dynamic. The indication information transmitted by the base station contains parameter changes that inform UEs about which resources are currently available for dynamic multiplexing, allowing the system to adapt resource characteristics in real-time while maintaining communication reliability through controlled transitions.
3Adaptability or versatility
If flexible resource configuration is implemented for dynamic multiplexing, then resource adaptability improves, but system complexity increases due to additional configuration management
Solution Approach 1:
The patent segments the resource configuration into two distinct parts: a semi-static baseline configuration that provides stability, and a dynamic indication configuration that provides flexibility. The indication information is transmitted separately and supplements the existing semi-static configuration, allowing the system to gain adaptability without completely redesigning the configuration management structure.
Solution Approach 2:
The patent performs preliminary configuration of semi-static resource allocations before dynamic multiplexing is activated. This preliminary setup establishes a stable foundation that reduces the complexity of subsequent dynamic adjustments, as the system only needs to manage changes and indications rather than complete resource allocation from scratch.

AI summary
The present disclosure relates to methods and devices for dynamic resource multiplexing. In one aspect, a base station can transmit a first uplink/downlink configuration for communicating with one or more User Equipments (UEs). The first uplink/downlink configuration can comprise a set of fixed resources configured for uplink communication without downlink resources for downlink communication or for downlink communication without uplink resources for uplink communication. The base station can also transmit a second uplink/downlink configuration for communicating with the one or more UEs. The second configuration can comprise a flexible resource configuration. Additionally, the base station can communicate with a least one of the one or more UEs based on the first uplink/downlink configuration or the second uplink/downlink configuration.
