Abstract: Techniques for handover into eIMTA enabled cells are disclosed. In an aspect, a target cell reconfigures RRC connection with a UE after completed handover to enable eIMTA and/or CoMP for the UE. In another aspect, a target cell includes eIMTA configuration information in a handover command to a UE. In another aspect, the target cell may estimate a virtual cell identity to generate the eIMTA configuration information and delay scheduling transmissions to the UE by flexible subframes until after handover is complete and the correct eIMTA configuration information confirmed by measurement or else corrected by RRC connection reconfiguration. In other aspects, the target cell may determine the correct virtual cell identity before handover, either by measuring SRS of the UE, or by receiving information in a handover request indicating results of CSI-RS measurement, by the UE, of virtual cells of the target cell.

Abstract: A technique is disclosed to minimize service interruption at a wireless user equipment device during a handover by maintaining dual active connections during the handover. Upon initiating the handover, an initial/first connection with a first access node is maintained while establishing a second connection with a second access node. The user equipment device can receive data over the first connection and second connection during the handover. The first connection may be terminated (by the user equipment device or by timing out due to inactivity) after the handover is completed. Other aspects, embodiments, and features are also claimed and described.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receiving information indicating an available MBMS service, a non-self-standing carrier frequency on which the available MBMS service is provided, and one or more PCC frequencies to which the non-self-standing carrier frequency is attached. The UE selects a preference for one PCC frequency of the one or more PCC frequencies in order to obtain information for receiving the available MBMS service on the non-self-standing carrier frequency. The UE receives the available MBMS service on the non-self-standing carrier frequency based on the obtained information.

Abstract: Various embodiments provide methods and apparatus for network-controlled DRVCC. In an embodiment method, a wireless user equipment may include requesting handover of a voice over Internet protocol (VoIP) call from a first network to a second network, activating a second radio, continuing the voice call on the circuit switched (CS) domain of the second network, and communicating data for applications other than the voice call via the first network. An embodiment method may include determining whether the first network supports voice-over-LTE (VoLTE) calls, and deactivating a radio in response to determining that the first network supports VoLTE calls. An embodiment method may include determining whether a quality of the VoIP call satisfies a quality threshold, deactivating the radio continued to the second network when the quality of the VoIP call satisfies the quality threshold, and activating the second radio when the VoIP call quality does not satisfy the quality threshold.
Abstract translation: 各种实施例提供了用于网络控制的DRVCC的方法和装置。 在一个实施方式中，无线用户设备可以包括请求通过因特网协议（VoIP）呼叫从第一网络到第二网络的切换，激活第二无线电，继续在电路交换（CS）域上的语音呼叫 第二网络，以及经由第一网络为不同于语音呼叫的应用传送数据。 实施例方法可以包括确定第一网络是否支持LTE语音（VoLTE）呼叫，以及响应于确定第一网络支持VoLTE呼叫来停用无线电。 一种实施方式可以包括确定VoIP呼叫的质量是否满足质量阈值，当VoIP呼叫的质量满足质量阈值时停用继续到第二网络的无线电，以及当VoIP呼叫质量不满足时激活第二无线电 满足质量门槛。

Abstract: Certain aspects of the present disclosure provide techniques for data collection for non-terrestrial networks (NTN). One aspect provides a method for wireless communications by a user equipment (UE). The method generally includes transmitting an indication of a capability of the UE to connect to a network via both terrestrial network (TN) cells and non-terrestrial network (NTN) cells and transmitting one or more data collection reports in accordance with the indicated capability.

Abstract: The present disclosure provides systems, methods, and apparatuses for maintaining continuity of a buffer status report (BSR) from a user equipment (UE) when the UE is handed over between base stations. In one aspect, a base station or a component thereof may be configured to allocate a set of resources for transmission by a UE. The set of resources may have a capacity that is insufficient for an amount of data indicated by a BSR from the UE. The base station or component thereof may be further configured to transmit, to another base station in association with handover of the UE, an indication that the capacity of the set of resources is insufficient for the amount of the data indicated by the BSR.

Abstract: Aspects described herein relate to receiving, from a network node, a list of supported models or model structures (MS) identifiers (IDs) per machine learning function name (MLFN) or machine learning feature (MLF) at the network node, updating a capability at the UE to an updated capability based on the list of supported models or MS IDs per MLFN or MLF at the network node, and downloading, at the UE and from a model repository, one or more models or MSs per MLFN or MLF based on the updated capability and available resources at the UE. Other aspects relate to transmitting the list of supported models or MS IDs and configuring use of a model or MS ID for a particular MLFN or MLF.

Abstract: A UE may select one or more paging attributes for paging reception. The one or more paging attributes may be selected from a set of network supported paging attributes. The UE may transmit, to a network, an indication of the one or more paging attributes for paging reception. The UE may receive, from the network, a response message based on the indication of the one or more paging attributes. The response message may include a first UE group number. The first UE group number may be based on at least the one or more paging attributes. The UE may receive a paging indication including a UE group number. The UE may proceed to receive and decode the paging message associated with the paging indication when the UE group number in the paging indication matches the first UE group number. Otherwise, the UE may safely disregard the paging message.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to performing a handover on a per-data radio bearer (DRB) basis. In some examples, the disclosure is directed to indicating, to a source network entity, a make-before-break (MBB) handover capability of the UE, the MBB handover capability supporting MBB handovers for one or more DRBs identified by the source network entity. In some examples, the disclosure describes receiving, from the source network entity, configuration information for a handover from the source network entity to a target network entity, the configuration information identifying the one or more DRBs supported for the MBB handover.

Abstract: Aspects described herein relate to interference mitigation for communication with muting via inter-cell coordination. In one example, a network entity such as a cell may identify a time or frequency resource allocated for communication with a user equipment (UE), and transmit, to a neighboring network entity, a muting message indicating that the time or frequency resource is occupied for communication. In another example, the network entity may receive, from a neighboring network entity, a muting message indicating that a time or frequency resource is occupied for communication. The network entity may further forgo scheduling of an uplink or downlink transmission to a UE on the indicated time or frequency resource. The network entity may further schedule data for uplink or downlink transmission with the UE on a different time or frequency resource.
