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.

Abstract: Performing a circuit-switched fallback (CSFB) call with improved reliability. A request to establish a CSFB call may be received by a UE that is currently in a pool overlap area. The network resource controller, or the base station, transmits information to the UE which indicates the pools in which neighboring cells are operating. The UE uses this information to select a circuit-switched cell on which to operate for the CSFB operation, wherein the selected CS cell is in the same pool area as the current pool area. This prevents the UE from inadvertently camping on a CS cell in a different pool area, which could cause call failure on some networks. The information provided by the base station may comprise a pool area id, or may comprise mapping relation information that is useable by the UE to determine the current pool area.

Abstract: Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.

Abstract: The techniques described herein include superior home-on-home roaming procedures by enabling user equipment (UE) to modify a home public land mobile network (HPLMN) search periodicity based on a likelihood of detecting an HPLMN cell (e.g., base station). A UE may be configured to determine a current geographic location of the UE, access a database that includes information about the HPLMN for the location (e.g., prior HPLMN searches), determine an appropriate HPLMN search periodicity based on the information, and perform HPLMN searches based on the appropriate HPLMN search periodicity. In some implementations, the UE may determine the HPLMN search periodicity based on a number (N) of HPLMN cells, and/or times an HPLMN cell sample, associated with the geographic area, has been detected previously.

Abstract: In some embodiments, a wireless device such as a user equipment (UE) may communicate with a base station using an advanced form of carrier aggregation. The UE may provide signaling to the network specifying a number P of downlink component carriers to be configured for use by the UE for downlink carrier aggregation and a number Q of uplink component carriers to be configured for use by the UE for uplink carrier aggregation. The UE can only utilize a lesser number M of downlink component carriers at any given time in downlink carrier aggregation and can only utilize a lesser number N of uplink component carriers at any given time in uplink carrier aggregation. Thus the UE may request the network to configure a greater number P and Q of downlink and uplink component carriers, respectively, than the UE can actually use at any instant of time.

Abstract: Embodiments described herein relate to wireless communications, including methods and apparatus for configuring synthetic electronic subscriber identity module (eSIM) profiles for wireless devices based on user credentials. A synthetic eSIM profile is generated at a wireless device based on transformation of user credentials that include a user identity and user cryptographic information. The user identity can include an identifier for a user account, and the user cryptographic information can include a password for the user account. The wireless devices can use the synthetic eSIM profile to obtain and load one or more fully functional eSIM profiles to an embedded universal integrated circuit card (eUICC) to without requiring a bootstrap eSIM profile or non-cellular wireless access.
