Description

Technical Field

[0001]

[0006] Generally speaking, aspects of the present disclosure relate to wireless communications and to techniques and apparatus for interruption measurements for dual active protocol stack switching and conditional switching. Background Art

[0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).

[0003] A wireless communication network may include multiple base stations (BS) that can support communications for multiple user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to a communication link from a BS to a UE, while an uplink (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0004] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global level. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to be better integrated with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), and using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), so as to better support mobile broadband Internet access, as well as support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

[0022] The following is a more complete description of various aspects of the present disclosure with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. More specifically, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether the aspect is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect. For example, using any number of aspects set forth herein, a device can be implemented or a method can be implemented. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0023] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0024] It should be noted that although various aspects may be described herein using terms commonly associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to communication systems based on other generations, such as 5G and later (including NR technology).

[0025] Figure 11 is a diagram showing a wireless network 100 in which various aspects of the present disclosure may be implemented. The wireless network 100 may be an LTE network or some other wireless network (e.g., a 5G or NR network). The wireless network 100 may include a plurality of BSs 110 (shown as BSs 110a, BSs 110b, BSs 110c, and BSs 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0026] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0027] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks, and / or similar interfaces using any suitable transport networks).

[0028] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0029] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0030] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0031] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0032] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or a connection to a network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component, a memory component, etc.).

[0033] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0034] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, etc.), mesh network, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0035] As noted above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0036] Figure 2 Base station 110 and UE 120 (which may be Figure 11. Block diagram of a design 200 of a base station 110 and a UE 120. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0037] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, a synchronization signal may be generated using position coding to transmit additional information.

[0038] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0039] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and provide decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0040] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component in the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with interruption measurements for dual active protocol stack (DAPS) handover and conditional handover (CHO), as described in more detail elsewhere herein. Figure 2 Any other component in may perform or direct e.g. Figure 6 The process of 600 Figure 7 The operations of process 700 and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120, the one or more instructions may perform or direct, for example, Figure 6 The process of 600 Figure 7 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0041] In some aspects, the UE 120 may include: a unit for detecting an interruption trigger for initiating a report of an interruption parameter associated with a DAPS handover procedure or a CHO procedure; a unit for reporting the interruption parameter to a base station based at least in part on detecting the interruption trigger, wherein the interruption parameter is used to indicate at least one of a duration of the handover interruption or a start time of the handover interruption; and the like. In some aspects, such a unit may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, etc.

[0042] In some aspects, the base station 110 may include: a unit for receiving an interruption parameter associated with a DAPS handover procedure or a CHO procedure from a UE, wherein the interruption parameter is used to indicate at least one of a duration of the handover interruption or a start time of the handover interruption; a unit for determining a duration of the handover interruption based at least in part on the interruption parameter; and the like. In some aspects, such a unit may include a unit for combining Figure 2 One or more components of the base station 110 are depicted, such as the antenna 234, the DEMOD 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the DEMOD 232, the antenna 234, and the like.

[0043] As noted above, Figure 2 is provided as an example. Other examples may differ from those described above. Figure 2 Examples described.

[0044] Figure 3 is a diagram illustrating an example 300 of performing a handover process according to various aspects of the present disclosure. Figure 3 As shown in , example 300 may include UE 120, source BS 110 (e.g., to which UE 120 is connected via a source connection), and target BS 110 (e.g., to which UE 120 is being handed over from source BS 110 and / or to which UE 120 will be connected via a target connection).

[0045] As indicated by reference numeral 310, the source BS 110 may determine that the UE 120 will perform at least one of a dual active protocol stack (DAPS) handover procedure or a conditional handover (CHO) procedure. In some aspects, the DAPS handover procedure may include a multi-stage handover, in which two protocol stacks are used to handover the UE 120 from the source BS 110 to the target BS 110. In the DAPS handover procedure, packet data convergence protocol (PDCP) functions may be split between the source BS 110 and the target BS 110. For example, sequence numbering / reordering functions may be maintained at the source BS 110, while other PDCP functions are independently run at both the source BS 110 and the target BS 110.

[0046] In some aspects, the CHO process may include a handover in which a handover command (e.g., a radio resource configuration (RRC) connection reconfiguration including mobility control information) is associated with a condition. For example, when the UE 120 determines that the condition is met, the UE 120 may perform the handover according to the handover command.

[0047] In some aspects, a dual-connectivity handover process may be performed and may include a handover in which the UE 120 is simultaneously connected to a source BS 110 as a master BS and a target BS 110 as a slave BS, and in which the source BS 110 and the target BS 110 communicate with each other to exchange roles (e.g., the source BS 110 becomes the slave BS and the target BS 110 becomes the master BS).

[0048] As indicated by reference numeral 320, the source BS 110 may send a handover indication, and the UE 120 may receive the handover indication. For example, the handover indication may indicate that the UE will perform at least one of a DAPS handover procedure or a CHO procedure. The handover indication may include a handover command associated with the DAPS handover procedure, a CHO trigger condition associated with the CHO procedure, etc. In some aspects, the handover indication may be included in an RRC connection reconfiguration request. For example, the RRC connection reconfiguration request may be sent from the source BS 110 to the UE 120. In some aspects, the RRC connection reconfiguration request may include a set of conditions that the UE 120 will use to select the target BS 110.

[0049] As indicated by reference numeral 330, UE 120 may perform at least one of a DAPS handover procedure or a CHO procedure. For example, UE 120 may perform at least one of a DAPS handover procedure or a CHO procedure based at least in part on a handover indication received from source BS 110.

[0050] like Figure 3 As shown in FIG, quality of service (QoS), mobility enhancement, etc. may be facilitated by core access and mobility management function (AMF) 340, radio access network (RAN) operation, administration, and maintenance (OAM) function 350, etc. Mobility enhancement for UE handover may have certain design goals, such as approximately zero millisecond handover interruption latency (e.g., for real-time gaming applications and other ultra-reliable low-latency communication (URLLC) applications), handover reliability, reduced handover ping-pong, etc. In order to meet these design goals, various types of handover enhancements may be used.

[0051] While these techniques may facilitate meeting design goals related to reliability and / or latency, the handover process may still result in service interruptions of varying durations and frequencies of occurrence. In some aspects described herein, techniques for reporting interruption parameters associated with a DAPS handover process, a CHO process, and / or a dual connectivity handover process are provided. Some aspects of the data collection techniques provided herein for mobility enhancement may enable network vendors and / or operators to evaluate handover interruption performance, which may facilitate optimizing resource allocation to reduce handover user data interruptions and improve handover robustness.

[0052] As noted above, Figure 3 Other examples are possible and may differ from the example described with respect to diagram 300 .

[0053] Figure 4 4 is a diagram illustrating an example 400 of interruption parameter reporting for a DAPS handover procedure or a CHO procedure in accordance with various aspects of the present disclosure. Figure 4 As shown in , UE 120 can communicate with source BS 110 and target BS 110.

[0054] As indicated by reference numeral 410, the UE 120 may detect an interruption trigger. The interruption trigger may be configured to cause the UE 120 to initiate a report of an interruption parameter associated with a DAPS handover procedure or a CHO procedure. In some aspects, the interruption trigger may include a handover command associated with a DAPS handover procedure, a CHO trigger condition associated with a CHO procedure, and the like.

[0055] In some aspects, as shown by reference numeral 420, the interruption trigger can be associated with the cessation of communication with the source BS 110. Communication may be stopped due to the UE 120 tuning away from the source BS 110, etc. In some aspects, the handover process can include a secondary cell group (SCG) change. The interruption parameters can correspond to the SCG change interruption.

[0056] In some aspects, detecting the outage trigger may include receiving an outage measurement activation indication from the source BS 110. The outage measurement activation indication may include a set of outage measurement configuration parameters, which may indicate an outage trigger.

[0057] As indicated by reference numeral 430, UE 120 may send an outage report and target BS 110 (or source BS 110, or other network element) may receive the outage report. The outage report may indicate an outage parameter 440 to BS 110 based at least in part on detecting an outage trigger. In some aspects, the outage parameter may indicate at least one of a duration of a handover outage or a start time of a handover outage.

[0058] In the case where the interruption parameter indicates a start time of the handover interruption, the target BS 110 may be configured to determine a duration of the handover interruption based at least in part on the start time of the handover interruption. The duration of the handover interruption may include an amount of time between the start time of the handover interruption and the end time of the handover interruption. As shown by reference numeral 450, the target BS 110 may detect the end time of the handover interruption.

[0059] In some aspects, the interruption parameter 440 associated with the DAPS handover procedure may correspond to an uplink interruption during the DAPS handover procedure. The start time of the handover interruption may include the time when the UE tunes away from the source cell (e.g., source BS 110). In some aspects, the end time of the handover interruption may include the time when a random access channel (RACH) procedure initiated by the UE 120 with the target cell (e.g., target BS 110) is successful.

The start time of the handover interruption may include a time when a CHO trigger condition is satisfied. The end time of the handover interruption may include a time when the CHO process is completed.

[0062] In some aspects, the CHO process includes a near-radio link failure (RLF) process, wherein an initial handover failure is followed by selection of a CHO candidate cell by the UE 120. Reporting the outage parameters to the BS 110 may include sending an enhanced RLF report. The enhanced RLF report may include a near-RLF parameter set. In some aspects, the near-RLF parameter set may indicate: a handover type (DAPS, CHO, etc.); a cell level (RSRP, RSRQ, etc.) corresponding to a serving cell; a beam level corresponding to a serving cell; a cell level corresponding to a CHO candidate cell; a beam level corresponding to a CHO candidate cell; RACH failure information (time expiration, no response to message 1, no response to message 3, conflict, etc.); a reason for the handover failure, wherein the reason for the handover failure includes a legacy handover failure or a failure to access a CHO candidate cell; a CHO signal parameter (RSRP, RSRQ, etc.), the CHO parameter indicates a signal measurement associated with a CHO candidate cell; and the like.

[0063] In some aspects, the techniques described herein for reporting handover interruption measurements may enable network vendors and / or operators to evaluate handover interruption performance, which may facilitate optimizing resource allocation to reduce handover user data interruption and improve handover robustness.

[0064] As noted above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0065] Figure 5 5 is a diagram illustrating another example 500 of interruption parameter reporting for a DAPS handover procedure or a CHO procedure in accordance with various aspects of the present disclosure.

[0067] In some aspects, the MDT configuration may be associated with a signaling-based MDT procedure. In some aspects, the MDT configuration may be associated with a management-based MDT procedure. In some aspects, the MDT procedure may be initiated by a RAN Operation, Administration, and Maintenance (OAM) function instead of or in addition to the AMF 510.

[0068] The MDT configuration may include an interruption measurement configuration parameter set 540. The interruption measurement configuration parameter set may indicate the handover types for which the UE will perform interruption measurements, the areas (e.g., one or more cells) within which the UE will perform interruption measurements, the maximum number of handover interruption measurements the UE will perform, and the like.

[0069] As indicated by reference numeral 550, UE 120 may detect an interruption trigger. The interruption trigger may be similar to the above in conjunction with Figure 4 The interruption trigger discussed. The interruption trigger may be configured to cause the UE 120 to initiate a report of an interruption parameter associated with the DAPS handover procedure or the CHO procedure. As indicated by reference numeral 560, the UE 120 may send and the target BS 110 may receive an interruption report. The interruption report may include the interruption parameter and may be sent to the target BS 110 based at least in part on detecting the interruption trigger.

[0070] In some aspects, the UE 120 may report the outage parameters to the target BS 110 by sending the outage parameters in an event-based report according to the immediate MDT. In some aspects, the event-based report may include at least one of a handover complete message, a dedicated outage measurement report, etc. In some aspects, the UE 120 may report the outage parameters to the BS 110 by sending the outage parameters in a log report according to the log-type MDT procedure.

[0071] In some aspects, the outage report may be sent to the target BS 110 in response to a request for an outage report from the target BS 110. In some aspects, the UE 120 may send an indication of the availability of the log report to the base station. The request for the outage report may be sent to the UE 120 in response to receiving the indication of the availability of the log report. The outage report may include an outage parameter and / or a handover parameter set, as described above in conjunction with Figure 4 As indicated by reference numeral 570, the target BS 110 may provide an MDT report to the AMF 510. The MDT report may include an interruption parameter and / or a handover parameter set.

[0072] In some aspects, the techniques described herein for reporting handover interruption measurements can enable network vendors and / or operators to evaluate handover interruption performance, which can facilitate optimizing resource configuration to reduce handover user data interruption and improve handover robustness. In some aspects, using MDT signaling to configure and report interruption measurements enables reporting to be accomplished without introducing additional signaling overhead.
