Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provided techniques that for wireless communications by a user equipment (UE). An exemplary method, performed by a UE, generally includes obtaining a first system information message from a wireless network configured to utilize Multimedia Broadcast multicast service Single Frequency Network (MBSFN) subframes and non-MBSFN subframes, determining, based on the first system information message, a first set of valid subframes and a first set of non-MBSFN subframes, obtaining a second system information message from the wireless network based on the first set of valid subframes and the first set of non-MBSFN subframes, and accessing the wireless network based on the first system information message and the second system information message.

Abstract: Techniques for optimizing user equipment radio capability signaling for wireless communications are described. In one technique, a type of network to access for communications is determined. A capability identifier(s) associated with a set(s) of user equipment (UE) radio capabilities is determined based, at least in part, on the type of network. The capability identifier(s) is sent to the network. Upon receiving an indication of the capability identifier(s), the set(s) of UE radio capabilities associated with the capability identifier(s) is identified and stored.

Abstract: A UE transmits to a source base station a capability of the UE associated with a bandwidth class or a band combination. The capability is associated with a handover in which the UE maintains connections with the source base station and a target base station. The UE receives a handover message comprising at least one of a target base station configuration to apply during handover execution or a source base station configuration to apply during handover execution based on the capability of the UE. The UE establishes a connection with the target base station and maintains a connection with the source base station over a period of time during the handover. The UE communicates with the source base station and the target base station during handover execution using at least one of the target base station configuration or the source base station configuration.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station (BS), an indication that the UE is to perform a conditional handover from the source BS to a target BS and is to perform at least one of: a two protocol stack handover from the source BS to the target BS or a dual connectivity handover from the source BS to the target BS. The UE may perform the conditional handover and at least one of the two protocol stack handover or the dual connectivity handover based at least in part on the indication. 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 receive a message that indicates a change from an evolved universal mobile telecommunications system (UMTS) terrestrial radio access (E-UTRA) packet data convergence protocol (PDCP) to a New Radio (NR) PDCP, wherein the message includes an instruction to perform an intra-cell handover; generate one or more security keys based at least in part on receiving the message that includes the instruction to perform the intra-cell handover; and communicate using the one or more security keys after the intra-cell handover is performed. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to dual connectivity reporting. In one example, a dual connectivity communication is established, which includes a communication with a master node according to a first radio access technology (RAT), and a communication with a secondary node according to a second RAT. A change in measurement capability is then detected, and subsequently reported to the master node and/or secondary node. In another example, a scheduling entity establishes a first or second communication of a dual connectivity communication with a scheduled entity. The first communication is established according to a first RAT when operating as a master node, and the second communication is established according to a second RAT when operating as a secondary node. An indication is then received from the scheduled entity of a change in measurement capability, and the first and/or second communications are reconfigured in response to the change in measurement capability.
