Base Station Resource Scheduling for Flexible Uplink Downlink Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies, such as 4G and 5G systems, lack the ability to flexibly adjust uplink and downlink resources according to throughput requirements, leading to inefficiencies and increased signaling burden.
Innovation Solution
A resource scheduling method that selects schedulable resource symbols based on interference conditions and adjusts them according to uplink and downlink throughput requirements, sending specific resource scheduling information to user equipment (UE) to adaptively configure frame structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uplink and downlink resource reconfiguration is performed through upper layer signaling for each UE, then resource allocation flexibility is improved, but signaling overhead increases significantly causing signaling storm
Solution Approach 1:
The patent segments the resource configuration into two parts: common resource configuration (sent once to all UEs) and UE-specific resource adjustments (sent only when changes are needed). This segmentation reduces redundant signaling while maintaining flexibility, as UEs can determine their specific resource allocation based on the common configuration plus minimal UE-specific indicators.
Solution Approach 2:
The patent changes the parameter representation from complete resource configuration messages to compact resource adjustment indicators. Instead of transmitting full reconfiguration information, the system transmits parameter changes (e.g., resource symbol index adjustments, resource block offsets) that UEs can apply to their existing configurations, significantly reducing signaling overhead.
2Productivity
If traditional frame structure with fixed DL/GP/UL proportions is used, then system complexity is reduced, but ability to adapt to different throughput requirements is worsened
Solution Approach 1:
The patent introduces dynamic resource symbol adjustment within the frame structure, allowing the boundaries between DL, GP, and UL resources to be flexibly repositioned based on throughput requirements. The base station can dynamically select from multiple candidate resource symbol configurations and notify UEs of the active configuration, enabling the frame structure to adapt to varying traffic conditions while maintaining manageable complexity through predefined configurations.
3Productivity
If resource symbols are selected based on interference situation, then resource allocation efficiency is improved, but scheduling complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-identifying and marking resource symbols that are suitable for scheduling based on interference conditions. The base station evaluates interference situations in advance and prepares candidate resource symbol sets before actual scheduling decisions are made, reducing the complexity of real-time scheduling while maintaining efficient resource allocation.

AI summary
The present application relates to the technical field of mobile communication and discloses a resource scheduling method, a base station, a user equipment (UE), an electronic device and a storage medium. The resource scheduling method is applied to the base station and includes: selecting schedulable resource symbols from the resource symbols in a reserved slot according to interference situation of resource symbols in the reserved slot; selecting several resource symbols from the schedulable resource symbols and generating resource scheduling information of the UE according to uplink and/or downlink throughput requirements of the UE, during a scheduling cycle of the UE; and sending the resource scheduling information to the UE. The resource scheduling information includes information indicating that the several resource symbols are adjusted to uplink and/or downlink resource symbols of the UE.
