Interface between host processor and wireless processor for artificial reality

Abstract

Disclosed herein are devices and methods related to an interface between a host processor and a wireless processor of a first device for maintaining an artificial reality session with a second device. In one aspect, the host processor is configured to provide data of the artificial reality session to the wireless processor, and the wireless processor is configured to transmit the data to the second device through a wireless medium. In one aspect, the host processor is configured to provide an indicator indicating an end of transmission of the data, to the wireless processor, to cause the wireless processor to transmit the indicator to the second device through the wireless medium, and to cause the host processor and the wireless processor to enter a sleep state in response to transmission of the indicator. The indicator may cause the second device to enter the sleep state.

         10 . The first device of  claim 9 , wherein the host processor is configured to schedule the scheduled time to enter the active state for the wireless processor, the host processor, the another wireless processor, and the another host processor. 
     
     
         11 . A method comprising:
 providing, by a host processor of a first device, data of a communication session to a wireless processor of the first device;   transmitting, by the wireless processor, the data to a second device through a wireless medium; and   providing, by the host processor, an indicator indicating an end of transmission of the data, to the wireless processor, to cause:
 the wireless processor to transmit the indicator to the second device through the wireless medium and to enter a sleep state until a scheduled time for additional data of a subsequent communication session, and 
 the host processor to enter another sleep state until the scheduled time, in response to transmission the indicator. 
   
     
     
         12 . The method of  claim 11 , wherein providing the data to the wireless processor of the first device includes providing the data to the wireless processor through a network layer of communication between the host processor and the wireless processor.
