Methods, devices, and systems for discontinuous reception for a shortened transmission time interval and processing time
First Claim
1. A method performed by a device, the method comprising:
- monitoring for data transmission scheduling assignments during an active time of a discontinuous reception cycle, and detecting a transmission during the active time;
determining a first timer value; and
starting a first timer, in response to the detecting, wherein the first timer is set for the first timer value that specifies an amount of time between detecting the transmission and starting a second timer that extends the active time by a second timer value;
wherein the first timer value is determined based on one or both of;
a selected first transmission time interval length from multiple transmission time interval lengths for which the device can be enabled;
ora selected shorter first processing time over a second processing time associated with a transmission time interval length used by the device; and
wherein at least one timer value adjustment factor is received from the network to use in determining the first timer value, where the at least one received timer value adjustment factor comprises a transport block size.

Abstract
A method and apparatus for discontinuous reception for a shortened transmission time interval and processing time includes a device monitoring for data transmission scheduling assignments during an active time of a DRX cycle, and detecting a transmission during the active time. The method further includes the device starting a first timer, in response to the detecting, wherein the first timer is set for a first timer value that specifies an amount of time between detecting the transmission and starting a second timer that extends the active time by a second timer value. The first timer value is determined based on one or both of a selected first TTI length from multiple TTI lengths for which the device can be enabled and/or a selected shorter first processing time over a second processing time associated with a TTI length used by the device.
