User Device Resource Configuration via Local Condition Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network providers face challenges in detecting conditions at user devices that affect communication quality, such as the Doppler effect, phase noise, and power status, leading to suboptimal resource configurations.
Innovation Solution
User devices are empowered to detect these conditions and initiate requests for resource configurations, such as numerology, mini-slot, and OFDM symbol schedules, allowing them to select settings better suited for their environment, which they then transmit to the base station for allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the provider (base station) manages resource allocation autonomously, then network control and management is simplified, but the provider cannot detect conditions at the user device that affect communication quality
Solution Approach 1:
The user device acts as an intermediary that detects local conditions (Doppler effect, phase noise, power status, thermal status) and translates them into resource configuration requests. This mediator role allows the base station to indirectly obtain device condition information without needing complex sensing capabilities at the base station itself.
Solution Approach 2:
The user device performs self-service by autonomously detecting its own operational conditions and selecting appropriate resource configurations based on those conditions. The device then communicates its needs to the base station through uplink transmissions, enabling the system to adapt to device-specific conditions without increasing base station complexity.
2Productivity
If the provider selects resource configurations, then network-wide optimization is possible, but suboptimal configurations are assigned due to lack of device-specific condition detection
Solution Approach 1:
The system transitions from uniform network-wide resource allocation to localized device-specific resource configuration. Each user device can request resource configurations tailored to its local conditions (mobility, power status, thermal status, data buffer state), ensuring that resource allocation matches the specific requirements of each device rather than applying a one-size-fits-all approach.
Solution Approach 2:
The user device monitors changes in operational parameters (Doppler effect indicating mobility, phase noise indicating oscillator quality, power status, thermal status) and adjusts resource configuration requests accordingly. This dynamic parameter-based adaptation allows the system to optimize communication quality in response to changing device conditions.
3Reliability
If user devices initiate resource configuration requests based on detected conditions, then communication quality adapts to device conditions, but additional signaling overhead is introduced
Solution Approach 1:
The user device performs preliminary detection of its operational conditions and pre-selects appropriate resource configurations before needing to transmit data. By having resource configuration requests ready in advance based on current device state, the system reduces the need for repeated signaling during active communication periods.
Solution Approach 2:
The system implements partial device autonomy where only certain devices or certain conditions trigger uplink resource configuration requests. Not every device continuously requests resource reconfiguration, but rather only when device conditions warrant a change, thus balancing adaptation benefits against signaling overhead.

AI summary
The present disclosure describes techniques and systems for user device-initiated requests for resource configuration. In some aspects, a user device can detect one or more conditions related to communicating with a base station over a wireless connection. The user device selects, based on the conditions, elements of a resource configuration for communicating with the base station. The user device then transmits a request indicating the selected elements of the resource configuration to the base station, which can then allocate resources to the user device based on the request. The elements of the resource configuration selected by the user device may include one or more of numerology configuration, mini-slot configuration, or a schedule for uplink and downlink OFDM symbols within a resource of the wireless network. This may allow the user device to influence a resource configuration that is better-suited for communication over one or more channels of the wireless connection.
