A method comprising receiving a first indication, from a terminal device, indicating that the terminal device is capable of supporting carrier aggregation, obtaining information regarding a battery level of the terminal device, estimating battery consumption per one carrier component, and based, at least partly, on the estimated battery consumption and information regarding the battery level, determining a number of additional carrier components to be activated for the terminal device.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of one or more periodic communications. The UE may receive an indication of a resource allocation for a communication. The UE may determine whether to receive the communication based at least in part on whether the resource allocation has resources within a threshold amount of time from a closest periodic communication of the one or more periodic communications. Numerous other aspects are described.

A communication apparatus includes a function for performing transmission and reception of a wireless signal in a period having a predetermined length which arrives at a predetermined time interval, a function for performing at least one process of the transmission and the reception of the wireless signal in the period as a substitute for a particular communication apparatus belonging to a set of a plurality of communication apparatuses among which the period is synchronized, and a function for deciding whether or not proxy processing is to be performed in accordance with a frequency of periods during which the communication apparatus performs the transmission and the reception of the wireless signal among a plurality of the periods.

A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier sturcture composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.

Methods and systems are provided for supporting efficient and secure “Machine-to-Machine” (M2M) communications using a module, a server, and an application. A module can communicate with the server by accessing the Internet, and the module can include a sensor and/or an actuator. The module, server, and application can utilize public key infrastructure (PKI) such as public keys and private keys. The module can internally derive pairs of private/public keys using cryptographic algorithms and a first set of parameters. A server can authenticate the submission of derived public keys and an associated module identity. The server can use a first server private key and a second set of parameters to (i) send module data to the application and (ii) receive module instructions from the application. The server can use a second server private key and the first set of parameters to communicate with the module.

Examples of electronic devices are described herein. In some examples, an electronic device includes a tracking device. In some examples, the electronic device includes a controller. In some examples, the controller may be to detect a power condition of the electronic device. In some examples, the controller may be to set a timer to deactivate the tracking device in response to detecting the power condition.

The present application relates to acquiring sensor data at a user equipment (UE). The described aspects include receiving a first input representing a request to activate one or more sensors. The described aspects further include activating, by a controller at the UE, the one or more sensors in response to receiving the first input. Further, the described aspects include receiving the sensor data from each of the one or more sensors in response to activating the one or more sensors.

In some embodiments, a user equipment device (UE) implements improved communication methods which include radio resource time multiplexing, dynamic sub-frame allocation, and UE transmit duty cycle control. In some embodiments, the UE may communicate with base stations using radio frames that include multiple sub-frames, transmit information regarding allocation of a portion of the sub-frames of a respective radio frame for each of a plurality of the radio frames, and transmit and receive data using allocated sub-frames and not using unallocated sub-frames. In some embodiments, the UE may operate according to a sub-frame allocation based on its current power state. The UE may transmit information to the base station and receive the sub-frame allocation based on at least the information. In some embodiments, the UE may switch transmit duty cycles based on an occurrence of a condition at the UE. The UE may inform the network of the switch.

A thermostat may include one or more temperature sensors, a processor configured to operate in a sleep mode and a wake mode, and a Wi-Fi chip that wirelessly communicates with a thermostat management server. The Wi-Fi chip may be configured to receive data packets from the thermostat management server while the processor operates in the sleep mode, and determine a priority level of the received data packets. The priority level may include a standard priority level and a keep-alive priority level. The Wi-Fi chip may also be configured to filter the received data packets based on the determined priority level of each packet such that the keep-alive priority level packets are discarded, and forward the standard priority level packets to the processor.

A system and method for updating industrial cellular communications devices. A supercapacitor and a cellular modem are connected electronically to one another. A host can communicate bidirectionally and wirelessly with the cellular modem. A microcontroller is connected electronically with the cellular modem, such that the microcontroller facilitates monitoring with the cellular modem of a voltage and temperature associated with the super capacitor. When the voltage of the super capacitor attains a lower voltage limit, the cellular modem stops receiving data from the host and sends a status code to the host and disconnects a data call and data transfer and enters into a sleep mode during which time the super capacitor is recharged. The cellular modem can reestablish the data call with the host after the super capacitor has been recharged.
