Abstract
Certain aspects of the present disclosure generally relate to wireless communications and, more specifically, to power savings based on distributed enhanced machine type communication (eMTC) functions, for example, between an applications processor and a modem of an eMTC device. An example method generally includes entering a power saving mode (PSM), wherein entering the PSM includes performing a first power collapse of an applications processor of the wireless node and a modem of the wireless node into a low power state; exiting the PSM at expiry of a wake-up timer, wherein exiting the PSM includes waking up the applications processor and the modem from the low power state to an active power state; and in response to exiting the PSM, performing a second power collapse of the applications processor into the low power state while the modem operates in the active power state.
