Patent number: 11864113Abstract: Methods, systems, and devices for wireless communication are described. A data layer at a user equipment (UE) may provide information associated with an uplink message to a modem power manager to determine whether to keep resources which are brought up by the scheduler or to power them off for transmitting the uplink message. For example, the data layer may indicate a radio access technology, a subscriber identifier, and a bearer type associated with the uplink message, which may enable the modem power manager to identify which radios to wake up (e.g., or avoid putting to sleep).
