US 12,587,965 B2 · Low-power modes for vulnerable road user equipment

Abstract

The present disclosure provides technologies and techniques for power optimization of vulnerable road user (VRU) devices in Intelligent Transportation Systems (ITS)/Vehicle-to-Everything (V2X) systems/networks, Internet of Things (IoT) devices, and/or other small form-factor devices. The power optimizations involve disabling or placing the communications functionality of a device in a sleep or inactive mode in situations where such functionality is not needed. The power optimization techniques include medium access control (MAC) optimized discontinuous reception (DRX) configurations, location-based communication, wake-up signaling communication, contextual activation and parameterization of device communication, slot reservation communication. Additional aspects of devices and communication configurations and arrangements may be described.

Dependent claims

A mobile station, comprising:

communication circuitry, wherein the communication circuitry is to:
receive a zone configuration, wherein the zone configuration includes a set of geographic areas at which the mobile station is to activate or deactivate the communication circuitry, wherein to activate the communication circuitry includes to enter an active state, and wherein to deactivate the communication circuitry includes to enter a sleep state;
and
adjust a subset of DRX parameters of the set of DRX parameters based on the geographic areas included in the zone configuration;
and
processor circuitry connected to the communication circuitry, wherein the processor circuitry is to:
cause the communication circuitry to enter the active state when a set of first conditions are met;
and
cause the communication circuitry to enter the sleep state when a set of second conditions are met, wherein the set of first conditions are different than the set of second conditions.

6 more elements

A non-transitory computer readable media (NTCRM) comprising instructions for operating a mobile station, wherein execution of the instructions is to cause the mobile station to:

receive a zone configuration, wherein the zone configuration includes a set of geographic areas at which the mobile station is to activate or deactivate communication circuitry of the mobile station, wherein to activate the communication circuitry includes to enter an active state, and wherein to deactivate the communication circuitry includes to enter a sleep state;
adjust a subset of DRX parameters of the set of DRX parameters based on the geographic areas included in the zone configuration;
determine a current position of the mobile station;
cause the communication circuitry of the mobile station to enter the active state when a set of first conditions are met;
and
cause the communication circuitry to enter the sleep state when a set of second conditions are met, wherein the set of first conditions and the set of second conditions are evaluated based on a comparison of the current position of the mobile station to the set of geographic areas at which the mobile station is to activate or deactivate the communication circuitry.
