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: The disclosure provides for selectively utilizing an inactive mode for saving power during wireless communications. A user equipment (UE) may transmit a first data packet for a first bearer using a Hybrid Automatic Repeat request (HARQ) process to a base station on a first channel. The UE may receive at least two acknowledgments, for the HARQ process on a second channel different than the first channel indicating that the first data packet was successfully received by the base station. The UE may determine whether a second data packet is communicated for the first bearer or a second bearer. The UE may also determine, based at least in part on the determination of whether the second data packet is communicated, whether to enter into an inactive mode in which at least the second channel is not decoded.

Abstract: A user equipment (UE) can establish a first connection using a first radio access technology (RAT), wherein the UE operates in a communication mode having one or more dormant periods with respect to the first connection. The UE can receive a data packet over a second connection using a second RAT, wherein the data packet is from a data flow which is allowed or configured to be delivered via the first connection and the second connection. It can be determined that the data packet is received over the second connection when the UE is operating in a dormant period of the one or more dormant periods with respect to the first connection. A termination of the dormant period over the first connection can be requested based at least in part on determining that the data packet is received when the UE is operating in the dormant period.

Abstract: Methods and apparatuses are provided that include enhancing decoding of multicast broadcast control communications, which can be of a relatively large size. A configuration message related to a broadcast channel structure can be received in multiple instances and/or segmented data units. A receiver can combine multiple instances and/or accumulate segmented data units to obtain and/or decode a control channel over which the configuration message is communicated. Communicating segmented data units of the configuration message can allow a broadcast station to utilize a lower data rate, more reliable modulation and coding scheme to encode the configuration message.
