Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a user equipment performs an inter-radio access technology (RAT) mobility procedure from a first network to a second network while idle mode signaling reduction (ISR) is active, locally deactivates ISR in connection with completion of the inter-RAT mobility procedure, and initiates a location management procedure in the second network. Depending on the respective type of the first and second network, and the connection state of the UE with respect to the first network, the mobility procedure may be performed in response to a mobility command received from the first network, or in response to a mobility condition of the first network as detected by the UE.

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: A client device includes a memory comprising a buffer for buffering data having real-time constraints and a hardware-based processor comprising digital logic circuitry. The processor is configured to execute a real-time application configured to determine times during which the data will be available for download, determine a time at which the data is needed to prevent a buffer underrun for the buffer, and when the data is available, send a request for the data and deadline information representative of the time at which the data is needed to avoid the buffer underrun. In this manner, a sending device can prioritize delivery of the requested data to prevent the buffer underrun for the client device.

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, a logged measurement configuration including a PLMN ID and a NID, the logged measurement configuration further including at least one of a trace reference, a logging area, a MDT PLMN list, or a MDT NPN list. The apparatus may also store the PLMN ID and the NID based on the received logged measurement configuration. Additionally, the apparatus may compare the PLMN ID and the NID to an MDT SNPN list to identify if the PLMN ID and the NID are included in the MDT SNPN list. The apparatus may also transmit, to the base station, an availability indicator if the PLMN ID and the NID are included in the MDT SNPN list.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure quality of experience (QoE) metrics and transmit a QoE report that is formatted to be readable by a base station, such that a base station may receive the QoE report and independently perform adjustments associated with the service being utilized by the UE. A UE may receive a configuration message that includes a first configuration for reporting QoE measurements to a base station and a second configuration for reporting QoE measurements to a QoE server. The UE may measure one or more QoE metrics in accordance with the configuration message, and generate a first report for the base station based on the QoE measurements and the first configuration. Upon generating the report, the UE may transmit the first report to the base station in accordance with the first configuration.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first base station and a second base station may be neighbor base stations and the first base station may receive, from the second base station, information relating to a multicast-broadcast services (MBS) session context of an MBS session supported by the second base station. The first base station may use the received MBS session context information to control communication or connections between the first base station and one or more user equipment (UEs) that are served by the first base station. For example, the first base station may use the received MBS session context information for target cell selection in a handover procedure, an MBS-specific measurement configuration, interference avoidance, or system information block (SIB) construction, among various other use cases.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a multicast or broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode (AM). The UE may determine an adjustment of an RLC AM transmission window of a base station. The RLC AM transmission window may be associated with retransmission of RLC packets associated with the MRB. The UE may synchronize an RLC AM reception window of the UE with the RLC AM transmission window based at least in part on determining the adjustment of the RLC AM transmission window of the base station. The RLC AM reception window may be associated with reassembly of RLC packets associated with the MRB. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may selectively determine to decode a downlink shared channel multicast transmission based on whether the downlink shared channel includes a retransmission of an initial multicast transmission. A base station may transmit a message in a downlink control channel to indicate if the downlink shared channel is carrying the retransmission of the initial multicast transmission. For example, the base station may transmit a group random network temporary identifier, downlink control information with a retransmission indicator bit, or both to indicate if the downlink shared channel is carrying the retransmission. In some cases, the message in the downlink control channel may be received at a layer one (L1) of the UE, and the downlink shared channel transmission may be decoded at L1 of the UE and sent to a layer two (L2) of the UE for processing.
