Abstract: A multi-SIM wireless communication device uses various techniques for managing component carrier conflict between different wireless networks. In some aspects, the multi-SIM wireless communication device can indicate to a network entity when a component carrier is muted due to a conflict between carriers of different subscriptions when the device enters a dual-SIM dual active (DSDA) mode or performs DSDA operations.

Abstract: A method and apparatus for a mobile communication device such as a mobile telephone includes a communication system that operates using narrow band-internet of things communication. The mobile communication device switches from communication using a mobile telephone communication system to communication using the narrow band-internet of things communication upon occurrence of a condition. The condition may include the mobile communication apparatus being out of range of a base station for the mobile telephone communication network or the battery level of the mobile communication device falling below a threshold. The mobile communication apparatus may switch from discontinuous reception to extended discontinuous reception If the battery power falls below a second threshold, or may switch to a power save mode if the battery power falls below a third threshold. Fewer services are available with the narrow band-internet of things communication, but the range is extended and power usage is less.
