Abstract: Access terminals are adapted to dynamically decrease awake state durations (and conversely increase sleep state durations) when operating in a slotted idle mode. According to one example, an access terminal can determine an offset corresponding to a time difference between the beginning of a preceding slot cycle and receipt of a first packet transmission. The access terminal can store information corresponding to the determined offset, and can employ the stored information to power on a receiver circuit after the beginning of a subsequent slot cycle by an amount of time corresponding to the determined offset. Other aspects, embodiments, and features are also included.

Abstract translation: 接入终端适于在以时隙空闲模式操作时动态地降低唤醒状态持续时间（并且相反地增加睡眠状态持续时间）。 根据一个示例，接入终端可以确定与前一时隙周期的开始和第一分组传输的接收之间的时间差相对应的偏移。 接入终端可以存储与所确定的偏移相对应的信息，并且可以使用所存储的信息在接下来的时隙周期开始之后的接收机电路上接通与所确定的偏移相对应的时间量。 还包括其他方面，实施例和特征。

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: Certain aspects of the present disclosure generally relate to wireless communications and, more specifically, to enhanced or evolved machine type communication (eMTC) power saving mode (PSM) enhancements for service outage. An example method generally includes receiving, from a modem of the wireless node, a first indication that indicates at least one of: network connectivity or network accessibility at the wireless node; receiving, from an applications processor of the wireless node, a second indication that indicates at least one of: server accessibility or availability of one or more applications; and determining when to enter a PSM based, at least in part, on at least one of: the first or second indications.
