Power enhancement techniques for vehicle-to-pedestrian wireless communication systems

A method for wireless communication by a vehicle user equipment (UE), comprising:

• identifying a wake up configuration for a wake up time period;
• receiving, within a first portion of the wake up time period, a message within a first resource pool that comprises an identifier of a first UE and at least one of location data of the first UE, sensor data of the first UE, or trajectory data of the first UE based at least in part on the wake up configuration;
• and
• transmitting a paging signal within a paging occasion of the wake up time period based at least in part on receiving the message and at least one of the location data, the sensor data, or the trajectory data, wherein a resource of the paging occasion is adjacent in time to a resource of the first resource pool.

A method for wireless communications by a user equipment (UE), comprising:

• identifying a paging occasion for a first radio access technology (RAT) that is different than a paging occasion of a sidelink RAT;
• transmitting, via the sidelink RAT, a message that comprises an identifier of the UE during a first portion of a wake up time period positioned relative to the paging occasion of the first RAT;
• and
• monitoring, during a second portion of the wake up time period that occurs relative to the first portion and based at least in part on transmitting the message that comprises the identifier of the UE, for a collision warning message from a vehicle UE that comprises the identifier of the UE, wherein a resource of the first portion is adjacent in time to a resource of the second portion.

A method for wireless communications by a vehicle user equipment (UE), comprising:

• receiving, from a first UE, paging cycle information that indicates a paging cycle of a wake up time period for a sidelink radio access technology (RAT) relative to a paging occasion configured for the first UE by a first RAT;
• receiving a message that comprises an identifier of the first UE during a first portion of the wake up time period that occurs relative to the paging occasion of the first RAT;
• and
• transmitting, based at least in part on the message, a collision warning message during a second portion of the wake up time period that occurs relative to the first portion, wherein a resource of the first portion is adjacent in time to a resource of the second portion.
