Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems face challenges in improving signal reliability and efficiency, particularly in complex and dynamic environments, due to signal attenuation and blockage, which affect data throughput and power consumption.
Innovation Solution
Configuring user equipment (UE) with mode-specific default bandwidth parts (BWPs) and inactivity timers based on network entity operation modes, allowing for optimized communication parameters such as bandwidth and power usage, thereby enhancing reliability and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single default BWP configuration is used for all network modes, then device complexity is reduced, but communication reliability deteriorates due to inability to optimize for different traffic conditions
Solution Approach 1:
The patent implements dynamic BWP configuration where the network entity determines the appropriate default BWP based on current operation mode and traffic conditions. The UE is configured with multiple default BWPs corresponding to different network modes, and the network entity provides mode indications to select the appropriate configuration. This dynamic adaptation resolves the contradiction by allowing the system to switch between simplified and optimized configurations based on actual operating conditions.
Solution Approach 2:
The patent changes the parameter of BWP configuration from a static single configuration to multiple mode-specific configurations. By introducing mode-specific default BWPs with different bandwidth and parameter settings optimized for different traffic conditions, the system improves communication reliability while managing complexity through structured parameter variation across modes.
2Productivity
If bandwidth is increased to improve data throughput, then productivity increases, but power consumption increases
Solution Approach 1:
The patent applies local quality by configuring different BWP parameters for different network modes based on traffic conditions. For high-traffic modes, wider bandwidths are allocated to maximize throughput. For low-traffic modes, narrower bandwidths are used to reduce power consumption. This localized optimization of bandwidth allocation resolves the contradiction by matching resource usage to actual traffic demands rather than using a fixed high-bandwidth configuration.
Solution Approach 2:
The system dynamically adjusts bandwidth allocation through mode-specific BWP configurations. The network entity determines the appropriate BWP based on current traffic conditions and provides mode indications to the UE. This dynamic bandwidth adjustment allows the system to achieve high throughput when needed while conserving power during low-activity periods.

AI summary
Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE), including receiving, from a network entity, default bandwidth part (BWP) configuration information for a plurality of modes of operation of the network entity, the plurality of modes comprising a first mode and a second mode, and the default BWP configuration information indicating a first default BWP for the first mode and a second default BWP for the second mode; receiving, from the network entity, a mode indication indicating the network entity is operating in the first mode; and communicating with the network entity using the first default BWP based on receiving the mode indication and based on expiration of an inactivity timer.
