3. The method of claim 2 , wherein the duration of time for the HARQ process is a multiple of the time unit.
4. The method of claim 1 , wherein the time unit of the DRX timer is associated with a retransmission of a HARQ process in a plurality of HARQ processes.
5. The method of claim 1 , wherein the DRX timer is one of:
an HARQ round trip time (RTT) timer,
a drx-RetransmissionTimer, and
an uplink (UL) RetransmissionTimer.
6. The method of claim 1 , wherein the plurality of different numerologies are associated with a respective plurality of carriers and the time unit of the DRX timer is associated with a carrier in the plurality of carriers.
7. The method of claim 6 , wherein the plurality of carriers includes a first and second carrier mapping to a first and second frequency spacing respectively, and wherein a first time unit associated with the first carrier is a multiple of a second time unit associated with the second carrier when the second frequency spacing is the multiple of the first frequency spacing.
8. A wireless device, comprising:
a processor, and
a memory coupled to the processor and storing instructions thereon, the instructions, when executed by the processor, causing the wireless device to perform actions, the actions comprising:
determining a time unit of a discontinuous reception (DRX) timer based on one of a plurality of different numerologies each indicating a frequency spacing configuration, the time unit of the DRX timer being determined based on information of one of a plurality of different scheduling units; and
determining a value indicated by the DRX timer to be a duration of time for the DRX timer based on the time unit.
9. The wireless device of claim 8 , wherein the time unit of the DRX timer is associated with a Hybrid Automatic Repeat request (HARQ) process in a plurality of HARQ processes.
10. The wireless device of claim 9 , wherein the duration of time for the HARQ process is a multiple of the time unit.
