Abstract: The present disclosure describes a method and an apparatus for managing security mode command (SMC) integrity failures at a user equipment (UE). For example, a method is provided for managing SMC integrity failures which receives a SMC message at the UE from a network entity. A message authentication code for data integrity (MAC-I) failure based at least on a mismatch of a security parameter at the UE may be detected at the UE. Moreover, a corrective action may be performed at the UE in response to the detection of the MAC-I failure at the UE.

Abstract: Aspects described herein relate to throttling packet-switched (PS) call establishment in wireless communications. A circuit-switched (CS) call can be conducted by using a first radio access technology (RAT). A cell update (CU) procedure for a PS call using a second RAT can be detected as due to one or more conditions. A cause for the one or more conditions can be determined based on one or more parameters related to a transmitter or receiver. PS call establishment attempts can accordingly be throttled based at least in part on determining the cause for the one or more conditions

Abstract: An example method may include receiving, at a user equipment (UE), data on a primary carrier supported by the UE, wherein the UE exits a discontinuous reception (DRX) mode in response to receiving the data. Further, the example method may include determining from the data an indication at the UE that handling of one or more secondary carriers also supported by the UE is to be reactivated, wherein the handling of the one or more secondary carriers was deactivated at the UE when the primary carrier entered the DRX mode. In addition, the example method may include activating, at the UE, handling of the one or more secondary carriers in response to the indication.

Abstract: The present disclosure presents a method and an apparatus for cell reselection during a SRNS relocation at a UE. For example, the disclosure presents a method for stopping signaling radio bearers (SRBs) sending a response message for the first Cell Update Confirm or the URA Update Confirm message and waiting for a layer two acknowledgement (L2 ACK) message from the network entity, triggering a second Cell Update or a URA Update procedure in a newly selected serving cell of the UE when waiting for the L2 ACK message from the network entity and waiting for the second Cell Update Confirm or the URA Update Confirm message, and performing a corrective action at the UE after the triggering of the second Cell Update or the URA Update procedure when the UE is waiting for the L2 ACK message from the network entity. As such, a cell reselection during a serving radio network subsystem (SRNS) relocation at a UE may be achieved.

Abstract: Certain aspects of the present disclosure relate to apparatuses and methods for maintaining reachability at a user equipment (UE). In one aspect, the apparatuses and methods are configured to detect a change in a radio connection between the UE and a peer entity, wherein the change in the radio connection is associated with the UE entering an idle state, to communicate to the peer entity, in response to detecting the change in the radio condition, an indication that the UE is to enter the idle state and is reachable for a specified duration of time while in the idle state, and to enter the idle state after communicating the indication to the peer entity. In another aspect, the apparatuses and methods are configured to communicate to the peer entity an indication that the peer entity is not to attempt to reach the UE during the specified duration of time.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE identify, based on a support of a cell for the UE operating with reduced capability, a cell type of the cell. The cell type is one of a reduced capability (RC) type, a fallback (FB) type, or a neither (N) type, corresponding to various support for the UE operating with the reduced capability. The UE further configures a device mode, where the device mode includes an RC mode or a FB-allowed mode, and manages the connection between the UE and the cell based on the device mode and the cell type.

Abstract: The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.

Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE). The method generally includes: performing connection reestablishment in response to a triggering condition, the connection reestablishment comprising: suspending operation of at least one data radio bearer (DRB) for carrying user data, transmitting a connection reestablishment request to a base station (BS), receiving from the BS a connection reestablishment message, and transmitting a connection reestablishment complete message to the BS; and transmitting at least a portion of the user data over non-access stratum (NAS) signaling, before the operation of the at least one suspended DRB is resumed.
