Apple patents timer logic to manage data for extended reality devices
Apple describes a method for managing data transmission in extended reality (XR) applications using a specific timer. The system tracks when data is sent during active network periods and stops the timer when the device enters a low-power sleep mode to prevent conflicting transmissions.
In the filing’s own words
A user equipment (VE) is configured to operate the UE in a discontinuous reception (DRX) mode comprising a DRX OnDuration where the UR monitors a Physical Downlink Control Channel (PDCCH) and a DRX OffDuration where the UE does not monitor the PDCCH, transmit, during the DRX OnDuration, first data to a network or a device using a first grant, identify a first hybrid automatic repeat request (HARQ) process associated with the first grant, start a first timer associated with the first HARQ process upon transmitting the first data using the grant, wherein the UE is prevented from transmitting data using any configured grant (CG) associated with the first HARQ process while the timer is running and stop the first timer when the UE transitions from the DRX OnDuration to the DRX OffDuration.
What exactly they claim (claim 1)
1. A method performed by a user equipment (UE), comprising: operating the UE in a discontinuous reception (DRX) mode comprising a DRX OnDuration where the UE monitors a Physical Downlink Control Channel (PDCCH) and a DRX OffDuration where the UE does not monitor the PDCCH; transmitting, during the DRX OnDuration, first data to a network or a device using a first grant; identifying a first hybrid automatic repeat request (HARQ) process associated with the first grant; starting a first timer associated with the first HARQ process upon transmitting the first data using the first grant, wherein the UE is prevented from transmitting data using any configured grant (CG) associated with the first HARQ process while the first timer is running; and stopping the first timer when the UE transitions from the DRX OnDuration to the DRX OffDuration.
