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.

Abstract: Access terminals are configured to decrease awake state durations (and conversely increase standby state durations) utilizing a preamble skip operation. According to one example, an access terminal may assign a finger of a receiver to receive a control channel transmission at a time after a beginning of a preamble of the control channel transmission, and before an initial boundary of a slot after a first slot of the control channel transmission, the preamble of the control channel transmission including information corresponding to a data rate of the control channel transmission. The access terminal may further be configured to decode the control channel transmission in accordance with a predicted data rate. Other aspects, embodiments, and features are also included.

Abstract: Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine, using a real-time clock (RTC) included in a microcontroller, that a modem module is to exit a power saving mode; instruct a load switch to connect the modem module to a battery of the UE based at least in part on the determination; and instruct the modem module to exit the power saving mode based at least in part on the determination. Numerous other aspects are provided.
