    Abstract: Methods and apparatus are provided for avoiding attempts by a UE to attach to a RAT network when that RAT network is unavailable. According to certain aspects, the UE may detect scenarios when the RAT network is unavailable and take preemptive action to prevent the UE from attempting to acquire service on that RAT. For example, the UE may effectively remove that RAT from a list of supported RATs by sending a UE capability message indicating that RAT is not supported, which may prevent network-initiated transitions of the UE to that RAT. The UE may also remove the unavailable RAT from an internal list of supported RATs, which may prevent UE-initiated transitions to that RAT.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a multi-radio access technology (multi-RAT) dual connectivity (DC) (MR-DC) capable cell. The UE may assign a priority to the MR-DC capable cell based at least in part on whether information indicating whether dual connectivity is supported for the UE in a tracking area (TA) is available, the information indicating whether dual connectivity is supported for the UE in the TA, whether system information block (SIB) information indicating frequency bands supported by a network for MR-DC operation cell is available, or MR-DC connectivity information indicating whether at least one frequency band is available to support MR-DC operation. The UE may perform a cell selection procedure or a cell reselection procedure based at least in part on the priority assigned to the MR-DC capable cell. Numerous other aspects are described.

    Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

    Abstract: Aspects of the present disclosure propose systems and methods for managing assignment of short message service (SMS) message identifications (IDs) in a multimode device (e.g., mobile station). The proposed methods ensure that a unique message ID is assigned to each SMS transmitted by the mobile station (MS). Each retransmission of the SMS messages may be assigned a message ID similar to or the same as the previous transmission(s) of the SMS message. As a result, a network messaging center may be able to identify duplicate SMS messages that are marked with unique message IDs even if they are transmitted on different air interfaces and/or by different modems (modulators/demodulators).

    Abstract: Aspects of the present disclosure provided techniques for wireless communications, and more particularly, to techniques and apparatus for publishing service availability. According to certain aspects, a method for wireless communications by a user equipment (UE) is provided. The method generally includes providing status information to a presence server that the UE is available via the first network service, wherein the presence server is a network-based entity that provides presence status services for a plurality of destination devices including the UE, detecting one or more operational limitations that might prevent the UE from being available via the first network service, and updating the presence server, in response to the detecting, to indicate the UE is not available via the first network service.

    Abstract: Methods and apparatus are provided for device configuration (e.g., feature segment loading and system selection). Certain aspects of the present disclosure generally relate to operating a user equipment (UE) in a first radio access network (RAN) with a first set of modem features that supports the first RAN, detecting a second RAN not supported by the first set of modem features, and rebooting the modem software to load a second set of modem features that supports the detected RAN. For certain aspects, the first RAN may be a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network and the second RAN may be a Wideband-Code Division Multiple Access (W-CDMA) network or Long-Term Evolution (LTE) network. This allows features to be loaded into memory (e.g., only) when they are required to support a detected RAN, rather than loading an entire image, thereby conserving DRAM and increasing efficiency.
