Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced power saving mode (PSM) for an active time duration of a PSM with extended discontinuous reception (eDRX) configuration in a wireless communication system. In one aspect, a user equipment (UE) is configured to enter a deep sleep mode during inactive times of a PSM, and to operate in eDRX mode during the active times of the PSM. Operating in eDRX mode during the active times includes dividing each of the active time durations into at least one eDRX idle period and at least one eDRX paging period. The UE determines whether a set of criteria for implementing a variant of the PSM is met, and when the set of criteria is met, the UE implements the variant of the PSM, which includes powering down the UE to a deep sleep mode at least during eDRX idle periods.

Abstract: Techniques for extending battery life in a mobile device are provided. An example of a mobile device according to the disclosure includes at least one external motion detect sensor, a mobile device management module operably coupled to the at least one external motion detect sensor, the mobile device management module comprising at least one processor configured to detect a motion interrupt, load a partial image state into the mobile device management module, detect a motion that meets or exceeds while in the mobile device management module is in the partial image state, load a full image state into the mobile device management module, and enable the mobile device management module in a full active state.

Abstract: A data storage device includes: a controller; an engine for performing at least one of encryption and decryption; and a logic circuit. In response to receiving a memory access command, the controller controls the logic circuit to generate an initialization vector based on initialization information in a first portion of the received command, selects a key from a plurality of keys based on key information in a second portion of the command, and controls the engine to perform at least one of encrypting and decrypting plain text data specified by the received command using the initialization vector and the selected key.
