Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication networks, existing methods for configuring operating bandwidths for User Equipment (UE) often result in low bandwidth utilization ratios due to fixed bandwidth configurations that do not adapt to varying data transmission needs of UEs, leading to inefficient resource allocation.
Innovation Solution
A method and device for dynamically configuring the operating bandwidth of UEs by obtaining bandwidth capacity parameters, including maximum and minimum operating bandwidths and frequency band ranges, to determine and send bandwidth configuration information that aggregates carriers, allowing for flexible adjustments based on data transmission requirements.

Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed bandwidth configuration is used for UE, then the configuration is simple and stable, but the bandwidth utilization ratio is low and resource allocation is inefficient
Solution Approach 1:
The patent implements dynamic bandwidth configuration where the base station adjusts the operating bandwidth of UE based on real-time data transmission requirements. The bandwidth configuration information includes multiple bandwidth parts (BWPs) with different bandwidth sizes, and the base station can switch between them or allocate different BWPs to different UEs dynamically, transforming the static fixed bandwidth into a dynamic adaptable resource allocation mechanism.
Solution Approach 2:
The patent changes the bandwidth parameter from a fixed value to a configurable range. The bandwidth configuration information specifies a first bandwidth part with a first bandwidth and a second bandwidth part with a second bandwidth, allowing the system to adjust the operating bandwidth parameter according to actual data transmission needs, thereby improving bandwidth utilization without requiring complete reconfiguration of the communication system.
2Productivity
If the operating bandwidth is increased to meet high data transmission needs, then the data transmission rate improves, but the bandwidth utilization ratio decreases when data amount is small
Solution Approach 1:
The patent segments the total bandwidth into multiple bandwidth parts (BWPs), where each BWP represents a distinct bandwidth resource unit. The base station can allocate different combinations of BWPs to different UEs based on their data transmission requirements, allowing fine-grained control over bandwidth allocation and preventing waste of bandwidth resources when data amounts are small.
Solution Approach 2:
The patent implements partial bandwidth allocation where UEs are assigned only the bandwidth portions they actually need for current data transmission tasks. Instead of allocating the maximum available bandwidth to all UEs, the system allocates bandwidth partially and dynamically, matching the allocation level to the actual data transmission requirements to avoid resource waste.

AI summary
Embodiments of the present disclosure provide a method and a device for configuring an operating bandwidth and relate to the field of mobile communication technology. The method includes: obtaining bandwidth capacity parameters of user equipment (UE), wherein the bandwidth capacity parameters include a maximum operating bandwidth, a minimum operating bandwidth and a frequency band range that are supported by the UE; determining bandwidth configuration information of the UE according to the bandwidth capacity parameters, wherein the bandwidth configuration information includes a carrier identifier, an operating bandwidth and an operating frequency of each of at least one carrier, a sum of the operating bandwidths of all the carriers is not less than the minimum operating bandwidth and not more than the maximum operating bandwidth, and the operating frequency of each carrier is within the frequency band range; and sending the bandwidth configuration information to the UE, wherein the bandwidth configuration information is configured to aggregate the at least one carrier into an operating carrier by the UE. In the present disclosure, as the base station could dynamically configure the operating bandwidth for the UE according to the bandwidth capacity parameters of the UE, the bandwidth in the base station could be reasonably configured. Thus, the bandwidth utilization ratio is increased.
