Simultaneous BWP Activation for 5G NR Spectrum Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR systems cannot simultaneously activate multiple bandwidth parts (BWP) or numerologies, leading to inefficient spectrum utilization and service transmission, as activating one BWP deactivates the previous one, causing data transmission interruptions and wasting spectrum resources.
Innovation Solution
A method where a terminal receives control information to determine if multiple BWP pairs can be simultaneously activated, allowing for flexible activation of additional BWP pairs without deactivating existing ones, enabling concurrent transmission of multiple services and improving scheduling flexibility and spectrum utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one BWP is activated at a time, then the system maintains simple BWP management and clear resource allocation, but it cannot support simultaneous transmission of multiple types of services and leads to spectrum resource waste
Solution Approach 1:
The patent segments the bandwidth part configuration into multiple independently activatable BWP pairs, where each BWP pair can be independently controlled for different services. This allows simultaneous activation of multiple BWP pairs, enabling different services to use different numerologies without mutual interference, thus resolving the contradiction between service versatility and spectrum efficiency.
Solution Approach 2:
The patent introduces dynamic BWP pair activation mechanisms where the terminal can simultaneously activate multiple BWP pairs based on service requirements. The network can dynamically configure and activate appropriate BWP pairs for different services, allowing the system to adaptively switch between single-BWP and multi-BWP modes, thereby improving both service adaptability and spectrum utilization.
2Adaptability or versatility
If BWP switching is performed between two numerologies, then the terminal can use different numerologies for different services, but it causes radio frequency bandwidth conversion that interrupts data transmission
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple BWP pairs with different numerologies before service activation. When a service requires a specific numerology, the corresponding BWP pair is already prepared and can be immediately activated without requiring mid-transmission switching, thus eliminating transmission interruptions while maintaining numerology adaptability.
Solution Approach 2:
The patent introduces BWP pairs as intermediary structures that bridge different numerologies. Each BWP pair acts as an independent resource container that can be activated without affecting others, serving as a mediator that allows numerology switching without causing RF bandwidth conversion interruptions to ongoing transmissions.
3Productivity
If multiple BWP pairs are simultaneously activated, then the system can support concurrent transmission of multiple services with different numerologies, but it increases system complexity in BWP management and resource allocation
Solution Approach 1:
The patent segments resource management into independent BWP pair units, where each BWP pair can be independently configured, activated, and managed. This segmentation allows the network to control activation of specific BWP pairs based on service requirements without managing all BWPs globally, reducing management complexity while enabling multi-service concurrent transmission and improving spectrum utilization.
4Ease of operation
If a BWP is deactivated when another is activated, then the system maintains clear resource allocation boundaries, but it causes data transmission interruptions and reduces scheduling flexibility
Solution Approach 1:
The patent segments the resource allocation space into multiple independent BWP pair units that can be simultaneously active. This segmentation allows the network to activate multiple BWP pairs for different services without deactivating others, maintaining clear resource boundaries for each service while enabling flexible scheduling and eliminating transmission interruptions caused by mandatory BWP switching.

AI summary
The present invention discloses a resource configuration method and device, and a computer storage medium. The method includes: a terminal receives first control information transmitted by a network device, where a BWP which is currently activated by the terminal is a first downlink BWP and a first uplink BWP, and the first control information includes first indication information which is used to indicate that a BWP to be activated is a second downlink BWP or a second uplink BWP; and the terminal determines whether the first downlink BWP, the first uplink BWP, the second downlink BWP and the second uplink BWP are simultaneously activatable, if the first downlink BWP, the first uplink BWP, the second downlink BWP and the second uplink BWP are simultaneously activatable, the terminal maintains the first downlink BWP and the first uplink BWP in an activated state while activating the second downlink BWP and the second uplink BWP.
