Abstract: Systems, methods, and devices authenticate mobile network cellular cells using asymmetric/public-key cryptography algorithms (e.g., Digital Signature Algorithm (DSA)) through integrity protecting the cellular cells broadcasted messages (e.g., paging and/or system information blocks (SIBs) system information broadcast messages) by message authentication code (MAC).

Abstract: Coordinated leaving for a UE having a first SIM and a second SIM may include decoding, at a baseband processor, an RRC reconfiguration message associated with the first SIM received from a first network. A communication corresponding to the second SIM received from a second network is decoded while the baseband processor is processing the received RRC reconfiguration message. The communication received from the second network is determined to comprise a higher priority than the RRC reconfiguration procedure. Based on determining, a UAI message corresponding to the first SIM is encoded by the baseband processor for transmission to the first network. The UAI message is configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure. The first SIM is transitioned to an idle mode. An RRC request corresponding to the second SIM is encoded by the baseband processor for transmission to the second network.

Abstract: A user equipment (UE) is configured to receive a mobility configuration from a source cell of a network, wherein the mobility configuration includes at least one mobility measurement object, determine that a radio link failure (RLF) event has occurred on the source cell, searching for a primary cell (PCell) only on frequencies associated with the at least one mobility measurement object to reestablish a radio resource control (RRC) connection and reestablish the RRC connection with the PCell.

Abstract: A user equipment (UE) may establish a radio resource control (RRC) connection with a first cell of a cellular network and transmit signaling comprising an indication of enhanced radio link failure (RLF) recovery capability. The UE may receive one or more RRC messages comprising configuration information for RLF recovery on the first cell. The UE detect one or more RLFs corresponding to the first cell and further determine, via a connection reestablishment cell selection procedure, that the first cell is a suitable RLF recovery candidate cell. In response to the detection and determination, the UE may apply the configuration information for the first cell. The UE may then transmit signaling comprising a trigger indicating a RLF recovery to the cellular network and re-establish the RRC connection with the cellular network using the configuration information.

Abstract: Determining RRC processing delays for multi-subscriber identify module (MSIM) user equipments (UEs) may include decoding a capabilities message from a UE that indicates the UE is an MSIM UE that includes at least a first SIM and a second SIM. A communication for the first SIM of the UE may be encoded. The communication may be configured to cause the UE to perform a radio resource control (RRC) procedure. A transmission request received from the UE may be decoded. The transmission request may be associated with the RRC procedure. In response to receiving the transmission request, an uplink (UL) gram may be scheduled for the first SIM of the UE.

The communication received from the second network is determined to comprise a higher priority than the RRC reconfiguration procedure. Based on determining, a UAI message corresponding to the first SIM is encoded by the baseband processor for transmission to the first network. The UM message is configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure. The first SIM is transitioned to an idle mode. An RRC request corresponding to the second SIM is encoded by the baseband processor for transmission to the second network.

Abstract: This disclosure relates to a mobile device, comprising: a physical layer (PHY) system configured to process physical layer related operations; a higher layer system configured to process operations related to layers above the physical layer; and a communication channel established between the PHY system and the higher layer system for reporting a plurality of transactions to the higher layer system, wherein the PHY system is configured to consolidate the plurality of transactions based on a single wake-up message directed to the higher layer system.

Abstract: A user equipment (UE) explicitly accounts for a coverage enhancement (CE or sometimes called enhanced coverage) feature in a public land mobile network (PLMN) search and/or selection. By explicitly using CE indicators in PLMN search and/or selection, a UE can determine whether to use a PLMN that may only be available in CE mode for voice services or data services, or fail to meet criteria, such as high data rate, that cannot be provided in CE mode. For example a UE can use the PLMN search and/or selection with (1) automatic PLMN selection at switch-on or recovery from lack of coverage, (2) higher priority PLMN selection, (3) manual PLMN selection, and/or (4) limited service capabilities while in CE mode.
