In order to improve the management of the power consumption of electronic devices (such as cellular telephones), the operating mode of an interface circuit in an electronic device may be changed when certain commands are received. In particular, when one or more commands are received that disable data communication via the interface circuit and a cellular-telephone network and/or enable communication via another interface circuit in the electronic device and a wireless local area network (WLAN), the interface circuit may be transitioned to an operating mode in which data communication via the cellular-telephone network using a communication protocol that supports only data and no voice is disabled. For example, the communication protocol may include a Long Term Evolution (LTE)-compatible communication protocol.

Electronic device with reduced power consumption

Throttling of transition attempts to connected mode based on user context. A wireless device may camp on a serving cell. A motion state of the wireless device may be monitored. One or more connected mode transition procedures on the serving cell may be attempted. If at least a threshold number of connected mode transition procedures fail on the serving cell while the wireless device is stationary, further connected mode transition attempts may be throttled for up to a certain amount of time. Alternatively, or in addition, the wireless device may bar itself from camping on that cell for up to a certain amount of time. Either or both of throttling connected mode transition attempts or barring cells may also be based on other aspects of user context, such as display state.

User context aware throttling of transition attempts to connected mode

Described herein are methods performed by user equipment ('UE') for carrier aggregation deployment and organization in unlicensed bands. The method includes initiating a cell selection process with a target cell, wherein the target cell sends a plurality of information blocks, receiving a first information block, prior to reading a second information block, determining whether the target cell is suitable for the UE to camp on based on the first information block, and terminating the cell selection process when the target cell is determined to be unsuitable for camping based on the first information block. The terminating may include comparing data from the first information block to data stored in a database. The method further includes determining whether the UE is in a stationary state or is in a state of motion, and using this information to improve cell selection delay on target cell.

Systems and methods for cell selection and reselection by improving system information reading procedure

A method for measurement reporting to improve throughput when using multicarrier cells is disclosed. The method can include a wireless communication device performing a first measurement of a primary carrier and performing a second measurement of a secondary carrier. The method can further include the wireless communication device deriving a combined measurement as a function of the first measurement and the second measurement. The method can also include the wireless communication device reporting the combined measurement to a serving network.
