Abstract

Techniques are described for wireless communication. A base station may indicate to a UE, in a pre-wakeup period, whether the base station will transmit a grant to the UE. The pre-wakeup period may occur at the beginning of a DRX cycle. The base station may transmit an indication of a grant to the UE, and the base station may indicate a time period during which the UE may wake up to receive the grant. The indication may include scheduling information for the grant. The UE may select a DRX mode based on a configuration received from the base station, a traffic pattern, or scheduling history. The UE may monitor for the grant, and receive the grant. In other examples, the UE or the base station may identify that the grant was not received, and may reset a DRX cycle based on the identification.
