Abstract: Methods, systems, and apparatuses for wireless communication are described. A user equipment (UE) may receive information from a network node. The system information may include inter-frequency configuration and measurement reporting configuration. The UE may perform a measurement of a frequency or multiple frequencies that are associated with the inter-frequency configuration. Subsequent to the measurement, the UE may transmit a report of the measurement of the frequency or multiple frequencies to the network node during a radio resource control (RRC) connection procedure based on the measurement reporting configuration.

Abstract: Aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may determine whether to configure the UE for a first type of resource sharing or a second type of resource sharing between a first radio access technology (RAT) and a second RAT, wherein one or more UE resources are configured for use with the first RAT. The UE may reconfigure the one or more UE resources for use with the second RAT based at least in part on determining whether to configure the UE for the first type of resource sharing or the second type of resource sharing.

Abstract: Aspects of the present disclosure relate to performing a tune-away from a first radio access technology (RAT) to a second RAT. These techniques include, for example, a method in which one or more radio resources of a user equipment are tuned away from the first RAT (e.g., LTE technology) to the second RAT (e.g., legacy 2G/3G technology and/or Wi-Fi or Bluetooth technology). Based on detecting a need to tune away one or more radio resources, the UE may then determine a tune-away metric for each serving cell based on one or more performance impact factors associated with the serving cell being tuned away. The UE may select one or more of the cells to be tuned away based on the determined tune-away metrics. The UE may then tune one or more radio resources corresponding to the selected at least one cell away from the first RAT to the second RAT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during a packet data convergence protocol (PDCP) reordering timer period, whether one or more packet transfer criteria are satisfied. The UE may transfer, during the PDCP reordering timer period, one or more packets from a reordering window based at least in part on a determination that the one or more packet transfer criteria are satisfied. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service associated with a first subscriber identity module (SIM) of the UE and a first priority. The UE may initiate a second service associated with a second SIM of the UE and a second priority. The UE may switch the first priority and the second priority during at least part of the first service or the second service. The UE may perform a communication in accordance with at least one of the first priority or the second priority. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) determine that at least one packet of a set of packets for a downlink message is unsuccessfully received at a radio link control (RLC) layer of the UE due to a specific situation of a set of specific situations and may transmit the NACK message based on the missing packet (s) on an as needed basis rather than waiting for a timer to expire (e.g., a fast NACK mechanism). In some examples, the specific situations may include the UE missing packets after a measurement gap, missing packets based on wake up latencies for a discontinuous reception mode of the UE, missing packets due to interference from reference signals transmitted by neighboring cells, missing packets due to the UE not decoding retransmissions that have a same redundancy version (RV) of a downlink message, or a combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a parameter associated with a secondary cell group. The UE may perform an optimization response action for a dual connectivity mode of a first frequency parameter or a second frequency parameter when the parameter satisfies a threshold, wherein the optimization response action is associated with whether the secondary cell group is operating with the first frequency parameter or the second frequency parameter. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a device-configured split data threshold for utilizing split data radio bearers (DRBs). A method that may be performed at a user equipment (UE) includes setting a device-configured split data threshold to a value that is less than or equal to a network-configured split data threshold value in response to the network-configured split data threshold value being greater than a first buffer threshold value associated with a data buffer of the UE, monitoring an amount of data in the data buffer, and triggering a first scheduling request (SR) associated with a first communication link and a second SR associated with a second communication link in response to the amount of data in the data buffer being greater than the device-configured split data threshold value.

Abstract: A method of wireless communication, by a user equipment (UE), includes setting up a secondary cell group (SCG) with a second radio access technology (RAT) that differs from a first RAT associated with a master cell group (MCG). The method also includes communicating wirelessly via the secondary cell group and the master cell group. The method further includes predicting a radio link failure (RLF) for the secondary cell group based on multiple inputs to a machine learning model. The method still further includes routing data transmission from the secondary cell group to the master cell group, after predicting the SCG RLF.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold. The UE may receive, based on transmitting the feedback request message, a feedback response message corresponding to a first previously transmitted uplink packet of the at least one previously transmitted uplink packet.
