Dynamic Radio Capability Mode Indication for Wireless Devices

Solution Overview

Problem

Wireless devices face inefficiencies in resource consumption and Quality-of-Service (QoS) due to the allocation of unnecessarily high radio resources by wireless networks, which can lead to battery drain and poor user experience, especially when using high data rate technologies for applications that do not require them.

Innovation Solution

A method and apparatus for wireless devices to dynamically determine and convey a suitable radio capability mode to the network based on the data requirements of ongoing connections, concealing higher data rate capabilities when lower data rates are sufficient, thereby optimizing resource allocation and reducing unnecessary resource consumption.

1Speed

If the wireless device indicates higher radio capability modes to the network, then the network allocates higher data rate resources, but the device consumes more battery power and receives unnecessary resources

Engineering Contradiction:

Improvedata rateVSAvoidbattery power consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic radio capability mode indication where the wireless device selectively indicates different capability modes (e.g., HSDPA category, HSUPA category) based on the specific data connection requirements. The device transitions from static full-capability indication to dynamic capability indication, matching the indicated mode with actual application needs to avoid unnecessary high power consumption while maintaining adequate data rates.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of radio capability mode indication by introducing a selection mechanism where the device chooses from multiple predefined capability modes (R99 only, R99+HSDPA, R99+HSUPA, HSDPA only, HSUPA only) based on connection type and data requirements. This parameter change allows the device to optimize the balance between data rate and power consumption dynamically.
