    Abstract: System and methods for providing special radio provisions to link budget limited devices. Before establishing a cellular connection with a cellular network, a user equipment device (UE), such as a link budget limited UE, may negotiate the special radio provisions with the network by presenting requested profile information to the network, and receiving back approved profile information from the network. The UE may perform these communications either directly, via a non-cellular communication connection with the network, or indirectly, via a companion or proxy device. When the UE initiates a cellular connection with the network, both entities may use information specified in the approved profile information, which may improve efficiency of the connection. In some scenarios, the approved profile information may identify a class of devices to which the UE belongs. The approved profile information may also be used in establishing connections with other devices of the same class.

    Abstract: A user equipment (“UE”) that performs methods to connect to multiple radio access networks (RAN) including a home network RANs and roaming RANs to perform communications. An exemplary method performed by a UE initially connected to a Long Term Evolution radio access network (LTE-RAN) of a home network and registered with a voice over LTE (VoLTE) service of the home network to perform voice communications via the LTE-RAN, includes detecting a service disrupting event preventing VoLTE communication with the LTE-RAN, deregistering from the VoLTE service of the home network, scanning for available bands in the LTE-RAN of the home network and while scanning for the available bands in the LTE-RAN of the home network, connecting to a further radio access network (RAN) of the home network that allows circuit-switched communications with the home network, wherein the UE performs voice communications as circuit-switched communications via the further RAN.

    Abstract: This disclosure relates to techniques for UEs (including link budget limited UEs) to improve communications performance with a cellular network. A UE may be configured to provide a request (for a first process executed by the UE) for a high-bandwidth connection to a base station of a cellular network during a first RRC connection. In some embodiments, the RRC connection is established by another process. In some embodiments, the UE is configured to receive signaling from the base station indicating that the base station cannot satisfy the high-bandwidth connection request and the UE is configured not to send or receive data for the high-bandwidth connection during the first RRC connection in response to the signaling. In some embodiments, the UE is configured to re-send the request on a second, subsequent RRC connection that is not established by the first process. In some embodiments, the UE is configured to opportunistically re-send the request on subsequent RRC connections established by one or more other processes until the base station is able to grant the request.

    Abstract: This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.
