  • Publication number: 20240049095
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) using information identified via radio access technology (RAT) (e.g., Long Term Evolution (LTE)) to support communications in another RAT (e.g., New Radio (NR)). For example, the UE may receive, from a first base station operating according to a first radio access technology an indication of a high speed associated with a first wireless connection of the UE with the first base station. The UE may perform a channel estimation procedure for the first wireless connection to generate a Doppler value based on receiving the indication. The UE may apply the generated Doppler value to a frequency tracking loop or a time tracking loop for communications with a second base station via a second wireless connection, wherein the second base station is operating according to a second RAT.

  • Publication number: 20240007910
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

  • Publication number: 20230354156
    Abstract: A user equipment (UE) receives a SIB1 message from a base station. The SIB1 message lists first and second public land mobile network identifiers (PLMN IDs), the first PLMN ID having a corresponding tracking area code (TAC) and the second PLMN ID not having a TAC. The UE reports the first PLMN ID and TAC but not the second PLMN ID while performing PLMN selection. In another aspect, the UE unsuccessfully attempts to select or reselect to a shared cell of the base station with the second PLMN ID. In response to the failed attempt, the UE bars the shared cell as a candidate for cell selection/reselection, due to a missing TAC. When the UE attempts to select or reselect to the shared cell with the first PLMN ID, which may or may not have a TAC, the UE reevaluates the barring due to selection of the first PLMN ID.

  • Publication number: 20230319920
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with two subscriptions. The first subscription may support dual connectivity with one or more cell groups, such as a master cell group (MCG) and a secondary cell group (SCG), while a second subscription may not support dual connectivity. Each subscription may support communications with one or more radio access technologies (RAT). The UE may use the protocol stack for a RAT in the first subscription to receive idle-mode signaling, such as one or more paging messages, from the second subscription using the same RAT.

In another aspect, a device may modify, such as extend or shift, a network measurement gap to generate a modified measurement gap for monitoring control signals of another network for inter-RAT procedures. The device may modify the network measurement gap to align the network's measurement gap, such as LTE measurement gap, with a measurement window of another network, such as an SMTC window of a 5G network. Other aspects and features are also claimed and described.

  • Publication number: 20220312280
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a first subscription of the UE and a second subscription of the UE are associated with a same cell and are being used for a same radio access technology (RAT). The UE may activate a proxy subscription mode for the first subscription based at least in part on the determination that the first subscription of the UE and the second subscription of the UE are associated with the same cell and are being used for the same RAT, wherein the proxy subscription mode enables the UE to use the first subscription to perform one or more idle mode operations for the second subscription while the second subscription is in an idle mode. Numerous other aspects are provided.
