    Abstract: One feature pertains to a method that includes establishing a radio communication connection with a first radio access node (RAN) that uses control plane signaling connections to carry user plane data. The method also includes determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN. A reestablishment request message is transmitted to the second RAN that includes parameters that enable a core network node communicatively coupled to the second RAN to authenticate the wireless communication device and allow or reject reestablishment of the radio communication connection. The parameters include at least a message authentication code (MAC) based in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device.

    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment (UE), may receive a configuration of a page monitoring periodicity, and a configuration of a wake-up signal from a network node, such as a base station. The UE may perform discontinuous monitoring for a plurality of wake-up signals based at least in part on a wake-up signal periodicity, and receive the wake-up signal on the wake-up signal periodicity. The UE may then monitor for paging messages to receive paging information, or updates to system information, during a page monitoring period according to the page monitoring periodicity, the wake-up signal periodicity, the received wake-up signal, or a combination thereof.

    Abstract: Disclosed embodiments facilitate UE location determination in systems with dense PRS configurations, reduced PRS periodicity, frequency hopping, and involving UE inter-frequency measurements. The techniques may be applied to Bandwidth reduced-Low complexity (BL) UEs, or enhanced Machine Type Communication (eMTC) UEs or Further enhanced MTC (FeMTC) UEs and/or in LTE-M systems. A method on a UE may comprise: receiving a Reference Signal Time Difference (RSTD) measurement request; transmitting, in response to the RSTD measurement request, a dedicated gap request comprising a requested configuration of dedicated gaps; and receiving, in response to the dedicated gap request, a message comprising a dedicated gap configuration. The dedicated gap request may comprise a request for dedicated measurement gaps and the message may comprise a dedicated measurement gap configuration. In some embodiments, the dedicated gap request may comprise a request for dedicated autonomous gaps and the message may comprise a dedicated autonomous gap configuration.

    Abstract: Methods and devices are disclosed for enabling improved performance on a single-transmit multi-SIM wireless communication device. The wireless communication device may detect a voice communication on a modem stack associated with the first SIM and a data communication on a modem stack associated with the second SIM. The wireless communication device may identify a data rate used by the voice codec to encode uplink traffic channel (TCH) bursts in the voice communication, and determine whether the identified data rate used by the voice codec permits TCH burst cancellation. If it is determined that the identified data rate used by the voice codec permits TCH burst cancellation, the wireless communication device may downgrade a portion of the uplink TCH bursts scheduled on the modem stack associated with the first SIM.
