Abstract: This disclosure provides systems, methods and apparatuses for early measurement associated with configuring with multiple secondary nodes (SNs). In one aspect, the configuration of multiple SNs may be improved by allowing a master node (MN) to determine a multi-SN configuration based at least in part on measurements of actual channel conditions as seen by the UE. Enabling the MN to receive the measurement information early during a process associated with establishing a connection between the UE and the MN may thereby improve efficiency and reduce latency associated with the configuration of multiple SNs.

Abstract: This disclosure provides systems, methods, and apparatuses for low latency switching between a plurality of secondary nodes (SNs) based on a configuration for the plurality of the SNs provided to a user equipment (UE). In one aspect, the UE may obtain measurements for the plurality of the SNs according to the configuration during dual connectivity communications with a master node (MN). The MN or the UE may facilitate switching between the plurality of the SNs based on the measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive radio resource control (RRC) signaling indicating a duration for a timer to be used during a random access channel (RACH) procedure in which the UE transmits mobile-originated uplink data. While in an inactive mode, the UE may transmit the mobile-originated uplink data in a first message of the RACH procedure and the UE may start the timer based at least in part on transmitting the uplink data. The UE may monitor, while in the inactive mode and for the duration of the timer indicated in the RRC signaling, to detect a second message of the RACH procedure including mobile-terminated downlink data in response to the mobile-originated uplink data. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently collecting and reporting minimization of drive test (MDT) measurements for one or more radio access technology (RAT) types and/or for multiple base stations in a dual connectivity deployment. In one example, a user equipment (UE) may receive an MDT measurement configuration indicating a first RAT type for collecting measurements and a second RAT type for reporting measurements. In this example, the UE may use the measurement configuration to collect MDT measurements for the first RAT type, and the UE may report the MDT measurements to a base station associated with the second RAT. Further techniques for efficiently collecting and reporting MDT measurements in a dual connectivity deployment are also described herein.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is operating in a dual-connectivity configuration with a master node (MN) and a secondary node (SN). The UE may receive at least one request that the UE report MDT measurements. The UE may perform a first portion of measurements associated with the first base station and perform a second portion of measurements associated with the second base station. The UE may perform the measurements while the UE is operating in the dual-connectivity configuration. The UE may transmit one or more reports including information indicative of the first portion of measurements, information indicative of the second portion of measurements, or both.

Abstract: Inform a master node about the feasible of secondary node cells during resumption of dual connectivity may require a large message. Additionally, the message may need to be encrypted. A solution to overcome the size and security limitation is to report a short identifier (or index) which is only shared between the UE and the MN. Accordingly, an apparatus, e.g., a UE, may be configured to receive, from a master node, a configuration comprising a mapping of cell identities for a plurality of secondary cells for reporting SN measurements and transmitting an SN report comprising measurements for at least a subset of the plurality of secondary cells using the mapping of cell identities. The apparatus may be configured to receive, from a first master node, a configuration for MN-DC, enter an inactive state or an idle state, and resume a connected state with a second master node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to perform a conditional handover procedure to transfer from a source cell to a target cell of a plurality of candidate target cells. The UE may transmit, to the source cell, a conditional handover execution message to indicate the conditional handover procedure to transfer from the source cell to the target cell based at least at least in part on determining to perform the conditional handover procedure. The UE may communicate with the target cell to transfer to the target cell based at least in part on determining to perform the conditional handover procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include receiving from a master cell group of a dual connectivity environment a first message indicating that a secondary cell group of the dual connectivity environment is suspended, maintaining a lower layer configuration for the secondary cell group and modifying a measurement report configuration for the secondary cell group based on the first message and while the secondary cell group is suspended, receiving from the master cell group a second message indicating that the secondary cell group is no longer suspended, and reconnecting to the secondary cell group using the lower layer configuration for the secondary cell group based on the second message.

Abstract: Systems, apparatuses, and methods for configurations for small data transmission by which a user equipment transmits, to a base station, user data within a random access message in a radio resource control inactive state. The user equipment may receive, via broadcast system information and/or unicast messages from the base station, a configuration on support capability or parameters for small data transmission. Based on the received configuration, the user equipment may transmit user data to the base station. The user equipment may transmit a random access preamble on a resource separately reserved for small data transmission.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that improve data packet exchange between a UE in an inactive mode and a network. In certain configurations, the apparatus may receive, from a user equipment (UE) in an active mode, a first packet including a first identifier associated with an anchor base station, a second identifier associated with a UE context, and a payload. The apparatus may identify the anchor base station based at least in part on one or more of the first identifier associated with the anchor base station or the second identifier associated with the UE context. The apparatus may transmit a second packet to the anchor base station. The second packet may include at least a portion of the first packet.
