    Abstract: A system, a method and an apparatus are described. The apparatus comprise a modem that determines frequencies at which a transceiver of a wireless device is susceptible to interference generated by a different transceiver of the wireless device, and that modifies a search for a radio access network based on the one or more frequencies. The first transceiver may be susceptible to the interference by means of transmission of the interference through one or more circuits within the wireless device. A threshold power level may be modified based on an estimate of the power of the interference. The threshold power level may be used to determine presence of a pilot signal. The interference may be modeled based on a list of frequencies associated with one or more subscriptions of the wireless device. An order of searching for pilot signals may be modified.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may set a value associated with a delay budget report information element based at least in part on determining that the UE is to employ low latency communication with or via a base station. The UE may transmit a message, that includes the value associated with the delay budget report information element, to the base station to indicate that low latency communication is to be employed in association with a default bearer established between the UE and the base station. Numerous other aspects are provided.

    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 translation: 本公开的方面提出了用于管理多模设备（例如，移动台）中的短消息服务（SMS）消息标识（ID）的分配的系统和方法。 所提出的方法确保向移动台（MS）发送的每个SMS分配唯一的消息ID。 可以向SMS消息的每次重传分配与SMS消息的先前传输类似或相同的消息ID。 因此，即使网络消息中心在不同的空中接口和/或不同的调制解调器（调制器/解调器）上传输，网络消息传送中心也可能能够识别标记有唯一消息ID的重复SMS消息。

    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: Certain aspects of the present disclosure relate to methods and apparatus for transmission restriction. An exemplary method generally includes initiating a mobile originating (MO) call, determining availability of parameters for a first access gating mechanism for determining whether to bar or allow transmission of the MO call, selecting the first access gating mechanism or a second access gating mechanism, based on the determination of the availability of the parameters, and applying the selected gating mechanism to determine whether to bar or allow the MO call.
