Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing minimization of drive test (MDT) operations. For example, certain aspects provide a method for wireless communication. The method generally includes receiving, at a radio access network (RAN), a measurement configuration to start a trace of a user-equipment (UE), determining a transition of the UE to an inactive state, and sending one or more messages to coordinate the trace of the UE or indicate that the trace has failed in response to the determination.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive information indicating one or more candidate target secondary nodes (SNs) for a multi radio access technology dual connectivity (MR-DC) handover of a user equipment (UE), wherein the information indicates that the one or more candidate target SNs are associated with direct forwarding paths with a source radio access network (RAN) node of the UE; select a target SN from the one or more candidate target SNs based at least in part on the received information; and perform the MR-DC handover of the UE, wherein the selected target SN is different than the source RAN node of the UE, and wherein a configuration of the MR-DC handover is based at least in part on a direct forwarding path between the selected target SN and the source RAN node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a set of measurements related to a unicast service channel based at least in part on one or more reference signals associated with the unicast service channel and a set of measurements related to a multicast/broadcast service (MBS) channel based at least in part on one or more reference signals associated with the MBS channel. The UE may apply one or more communication parameters to ensure continuity for an MBS service. For example, in some aspects, the one or more communication parameters are based at least in part on the set of measurements related to the unicast service channel and the set of measurements related to the MBS channel. Numerous other aspects are provided.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a packet data convergence protocol (PDCP) entity of a receiver device receives, from a radio link control (RLC) entity of the receiver device, a plurality of RLC data packets received from a transmitter device over an RLC unacknowledged mode (UM) data radio bearer (DRB) or RLC transparent mode (TM) DRB. The PDCP entity generates a plurality of PDCP data packets corresponding to the plurality of RLC data packets. The receiver device determines to send a PDCP status report indicating a reception status at the receiver device of the plurality of PDCP data packets and transmits the PDCP status report to a PDCP entity of the transmitter device. The receiver device receives, in response to sending the PDCP status report, one or more PDCP data packets of the plurality of PDCP data packets that were not successfully received at the receiver device.

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.
