In the scheme, a first device may determine a relationship between a completion time of a positioning measurement and an available time of a serving cell of the first device, or a relationship between a first time length of a duration for performing the positioning measurement and a second time length of an effective duration of an uplink synchronization parameter in the serving cell. The mobility activity may then be appropriately handled based on the determined relationship.

Description

Technical Field

[0001] Various example embodiments of the present disclosure relate generally to the field of telecommunications, and in particular, to methods, devices, apparatus, and computer-readable storage media for processing positioning measurements. Background Art

[0002] In New Radio (NR) Non-Terrestrial Networks (NTNs), it is assumed that the User Equipment (UE) always has the capability of Global Navigation Satellite System (GNSS) measurements and will achieve its position based on the measured GNSS information. In the following, more work on supporting the Internet of Things (IoT) on Non-Terrestrial Networks (NTNs) will be discussed. The 3rd Generation Partnership Project (3GPP) assumes that the UE cannot operate both GNSS and IoT NTNs simultaneously, so the Radio Access Network Working Group (WG) 1 (RAN1) and RAN WG2 (RAN2) specify GNSS measurement gaps during which the UE can perform GNSS measurements without monitoring the Physical Downlink Control Channel (PDCCH) and performing other "3GPP tasks".

It should not be considered that the scope of the present disclosure is limited to the above-mentioned system.

[0065] As used herein, the term "network device" refers to a node in a communication network via which a terminal device accesses the network and receives services from it. A network device may refer to a base station (BS) or an access point (AP), such as a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), a NR NB (also referred to as a gNB), a remote radio unit (RRU), a radio head (RH), a remote radio head (RRH), a repeater, an integrated access and backhaul (IAB) node, a low-power node such as a femto, a micro), a non-terrestrial network (NTN) or a non-terrestrial network device (such as a satellite network device, a low earth orbit (LEO) satellite and a geosynchronous orbit (GEO) satellite, an aircraft network device, etc.), depending on the terminology and technology applied. In some example embodiments, a radio access network (RAN) split architecture includes a centralized unit (CU) and a distributed unit (DU) at an IAB donor node. An IAB node includes a mobile terminal (IAB-MT) portion that behaves like a UE toward a parent node, and a DU portion of an IAB node behaves like a base station toward a next-hop IAB node.

[0066] The term "terminal device" refers to any terminal device capable of wireless communication. As an example and not limitation, the terminal device may also be referred to as a communication device, a user equipment (UE), a subscriber station (SS), a portable subscriber station, a mobile station (MS) or an access terminal (AT). The terminal device may include, but is not limited to, a mobile phone, a cellular phone, a smart phone, a voice over IP (VoIP) phone, a wireless local loop phone, a tablet computer, a wearable terminal device, a personal digital assistant (PDA), a portable computer, a desktop computer, an image capture terminal device such as a digital camera, a game terminal device, a music storage and playback facility, a vehicle-mounted wireless terminal device, a wireless endpoint, a mobile station, a laptop embedded device (LEE), a laptop mounted device (LME), a USB dongle, a smart device, a wireless user equipment (CPE), an Internet of Things (IoT) device, a watch or other wearable device, a head mounted display (HMD), a vehicle, a drone, medical equipment and applications (e.g., remote surgery), industrial equipment and applications (e.g., robots and / or other wireless devices operating in industrial and / or automatic processing chain environments), consumer electronic devices, equipment operating on commercial and / or industrial wireless networks, etc. The terminal device may also correspond to the mobile terminal (MT) part of an IAB node (eg, a relay node).In the following description, the terms "terminal device", "communication device", "terminal", "user equipment" and "UE" may be used interchangeably.

[0067] As used herein, the terms "resource", "transmission resource", "resource block", "physical resource block" (PRB), "uplink resource" or "downlink resource" may refer to any resource used to perform communication (e.g., communication between a terminal device and a network device), such as a resource in the time domain, a resource in the frequency domain, a resource in the spatial domain, a resource in the code domain, or any other combination of time domain, frequency domain, spatial domain and / or code domain resources to achieve communication. In the following, unless explicitly stated, resources in the frequency domain and the time domain will be used as examples of transmission resources for describing some example embodiments of the present disclosure. It should be noted that the example embodiments of the present disclosure are also applicable to other resources in other domains.

[0068] As mentioned above, in NR NTN, IoT NTN or other types of NTN, it is assumed that the UE always has the capability of GNSS measurement and will achieve its position based on the measured GNSS information.

[0069] In some example embodiments, GNSS may be used by the UE to determine its position so that the UE can compensate for radio propagation between the UE and the satellite. For geosynchronous orbit, the UE should compensate for propagation delay (covering approximately 36,000 km), while for low earth orbit satellites, the UE also needs to compensate for Doppler and time shift due to satellite motion (approximately 7.5 km / s relative to the earth).

[0070] In the present disclosure, GNSS measurements may be triggered by a network device or a UE.

[0071] Specifically, in some example embodiments, the network device may trigger the UE to perform GNSS measurements during a scheduled gap. Additionally, in some example embodiments, the network device may at least support triggering the UE to perform GNSS measurements aperiodically. In the case of aperiodic triggering, the network device may use a media access control (MAC) control element (CE) or a radio resource control (RRC) signaling to trigger the UE to perform GNSS measurements. The triggering by the network device is expected to be based on the reported GNSS effective duration. When the UE is in connected mode, the UE may report the GNSS effective duration using a MAC CE. Additionally, in some example embodiments, the UE is also required to report a "GNSS position fix duration" (i.e., the time required for the UE to perform GNSS measurements) at least during the initial access phase. The parameter "GNSS position fix duration" may be used by the network device to determine the length of the GNSS measurement gap. In some example embodiments, a new downlink MAC CE may be introduced to trigger the connected UE to perform GNSS measurements.

[0072] In some example embodiments, for GNSS measurements in a connected radio resource control (RRC), if a network device aperiodically triggers a connected UE to perform GNSS measurements, the UE may reacquire a GNSS position fix in the event of a gap.

[0073] In some example embodiments, for GNSS measurement gaps triggered aperiodically by MAC CE, their duration may be configured by the eNB. Additionally, when the duration of the GNSS measurement gap is not included in the configuration of the eNB, the gap duration is equal to the duration of the last reported GNSS position fix for measurement.

[0074] In some example embodiments, if the UE does not receive a trigger for GNSS measurement from the network device, the UE may autonomously perform GNSS measurement. In this case, the network device and the UE should have a common understanding of when and how to start GNSS measurement. As a specific embodiment, when the UE is not available for scheduling during the GNSS measurement period, the UE may autonomously perform GNSS measurement when the GNSS valid duration expires.

[0075] As a specific embodiment, for GNSS measurement under RRC connection, if the network device triggers the UE in the connected state to perform GNSS measurement non-periodically. In addition, when configured to be able to trigger GNSS measurement autonomously, if the UE does not receive a trigger to perform GNSS measurement from the network device, the UE can autonomously reacquire GNSS.

[0076] In some example embodiments, from the perspective of RAN1, at least for the case where the frequency error and timing error are within the frequency and timing error requirements using traditional closed-loop time correction, uplink transmission may be allowed without reacquiring GNSS for a duration X after the original GNSS valid duration expires.

[0077] In some example embodiments, the UE is not required to transmit or receive any channel / signal during the aperiodic GNSS measurement gap duration before the UE successfully reacquires the GNSS.

[0078] In some example embodiments, the UE may report a GNSS position fix duration for a GNSS measurement via a 4-bit field with component values ​​[1, 2, 3, 4, 5, 6, 7, 13, 19, 25, 31, 6*n+1, ...].

[0079] In some example embodiments, the GNSS valid duration reported by the UE may be a remaining valid duration.

[0080] In some example embodiments, the UE may trigger a GNSS measurement report after each completion of a GNSS fix operation.

[0081] It can be seen that the eNB can trigger GNSS Measurement Gaps (MGs) aperiodically during which the UE can perform measurements, and the trigger can be based on the downlink MAC CE, and the network is free to decide when to trigger GNSS measurements.

[0082] Furthermore, if the UE does not receive an aperiodic trigger and if the UE is configured with such an autonomous GNSS MG configuration, the UE may autonomously reacquire GNSS. Additionally, the UE may report the remaining valid duration for the GNSS valid duration upon completion of the GNSS fix operation. This enables the UE and the eNB to have a common understanding of the UE's GNSS status, i.e., when it is valid and when it is expired.

[0083] As mentioned above, 3GPP assumes that the UE cannot operate GNSS and IoT NTN simultaneously, so RAN1 and RAN2 specify GNSS measurement gaps during which the UE performs GNSS measurements without monitoring the Physical Downlink Control Channel (PDCCH) and performing other "3GPP tasks". In addition, it is expected that improved GNSS operation will be studied and specified in the following aspects: new position fixes for UE pre-compensation during long connection times and reduced power consumption.

[0084] In some embodiments, when the UE is measuring GNSS, radio link management (RLM) may be suspended during the GNSS measurement gap. In addition, it is not expected that the UE acquires system information and GNSS position at the same time, and if the UE cannot complete the acquisition of system information block 31 (SIB 31) before the start of the GNSS measurement gap, the acquisition of SIB 31 may be postponed until the GNSS measurement is completed.

[0085] In some example embodiments, when the UE measures GNSS during GNSS MG, some operations may be stopped / suspended. Example operations include, but are not limited to: dataInactivityTimer may be stopped, execution of conditional handover (CHO) may be postponed, RLM-related timers may be stopped (e.g., timers related to RLF and re-establishment (e.g., T310, T311, and T301) should be suspended; T310 may be suspended; T310 may be extended), time alignment timer (TAT) processing may be suspended / stopped (e.g., timeAlignmentTimer expires, TAT is suspended); unnecessary neighbor cell measurements may be avoided during the duration of GNSS measurement; random access channel (RACH) / scheduling request (SR) / buffer status report (BSR) may be suspended.

[0086] So far, although some discussion and agreement have been reached on UE / network behavior, there are still many outstanding issues that need further discussion. For example, it has been agreed that certain AS operations should be suspended when the UE performs GNSS measurements during a GNSS measurement gap. However, there has been no discussion on whether the suspended AS operations should be resumed when the UE completes the GNSS measurements.

[0087] Another outstanding issue is that while it has been agreed to suspend RLM during GNSS MG, the impact on RRM measurements is not defined, nor is it defined how the UE should "recover" from missing RLM measurements. Another outstanding issue is that there has been no discussion regarding RRM measurements that conflict with GNSS MG.

[0088] Furthermore, it has been agreed that the UE does not need to transmit or receive during the GNSS measurement gaps, and that the GNSS position fix duration used by the network to configure the GNSS measurement gaps is in the range of [1, 2, 3, 4, 5, 6, 7, 13, 19, 25, 31, 6*n+1, ...] seconds. This means that the UE cannot perform any RLM and RRM measurements for a very long period of time (up to 31 seconds or even more). In this case, normal mobility activities may be affected. Furthermore, for AS operations that are suspended when the UE performs GNSS measurements during GNSS MG, it is not clear whether the AS operations should be resumed / continued when the UE completes the GNSS measurements.

[0089] In view of this, how to specify the behavior of terminal equipment and network equipment during GNSS measurement gaps remains to be discussed.

[0090] According to some exemplary embodiments of the present disclosure, a solution for specifying the behavior of terminal devices and network devices in non-continuous coverage is provided. In this solution, a first device (e.g., a terminal device) can determine the relationship between the completion time of a positioning measurement (e.g., a GNSS measurement or a positioning measurement based on 3GPP signaling) and the available time of a serving cell of the first device, or determine a first time length of the duration for performing the positioning measurement and a second time length of the valid duration of an uplink synchronization parameter in the serving cell. Then, based on the determined relationship, RRM / RLM / AS activities can be appropriately processed.

[0091] In summary, since RRM / RLM / AS activities can be defined after the GNSS measurement is completed, unnecessary power consumption can be avoided and communication interruptions are minimized.

[0092] It should be noted that any section / subsection headings provided herein are not intended to be limiting. Embodiments are described throughout this document, and any type of embodiment may be included under any section / subsection. Furthermore, embodiments disclosed in any section / subsection may be combined in any manner with any other embodiments described in the same section / subsection and / or in different sections / subsections.

[0093] As used herein, the terms "serving coverage", "serving cell", "serving area", "source cell", "source network", "serving satellite", "serving network", "serving gNB", and "serving eNB" may be used interchangeably.

[0094] As used herein, the terms "candidate cell / network", "target cell / network", and "neighboring cell / network" may be used interchangeably.

[0095] As used herein, the terms "gap," "duration," "period," "cycle," "length of time," and "window" may be used interchangeably.

[0096] In the following, satellites will be used as examples of network devices to describe some specific example embodiments of the present disclosure. Note that the example embodiments described with respect to satellites are also applicable to other types of network devices. The present disclosure is not limited in this regard. Example Environment

[0097] Figure 1 An example communication environment 100 is shown in which example embodiments of the present disclosure may be implemented. In the communication environment 100, a plurality of communication devices including a first apparatus 110 and a second apparatus 120 may communicate with each other.

[0098] exist Figure 1 In the example of , the first device 110 may include a terminal device, and the second device 120 may include a network device serving the terminal device. The service area of ​​the second device 120 may be referred to as a cell 130. It should be understood that the second device 120 may be deployed in or outside the cell 130 according to different demand scenarios.

[0099] In some example embodiments, the communication environment 100 is an NTN network including one or more satellites. In some example embodiments, access network equipment (such as gNB) may be deployed at the satellite (also referred to as a regenerative architecture). Alternatively, in some example embodiments, the access network equipment may be deployed separately from the satellite, such as on the ground, also referred to as a transparent architecture. In the present disclosure, depending on the specific application scenario or requirements, either or both of the satellite and the access network equipment may be regarded as the second device 120. The present disclosure is not limited in this respect.

[0100] Additionally, in some example embodiments, either or both of the first device 110 and the second device 120 may move over time, which may cause the positional relationship between the first device 110, the second device 120, and the cell 130 to be changed.

[0101] like Figure 1 As shown, the cell 140 may be a neighboring cell, a candidate cell, or a target cell of the first device. In some example embodiments, the cell 140 may be provided by the third device 125.

[0102] In the following, for the purpose of illustration, some example embodiments are described in which the first device 110 operates as a terminal device and the second device 120 operates as a network device. However, in some example embodiments, the operations described in conjunction with the terminal device may be implemented at a network device or other device, and the operations described in conjunction with the network device may be implemented at a terminal device or other device.

[0103] In some example embodiments, if the first device 110 is a terminal device and the second device 120 is a network device, the link from the second device 120 to the first device 110 is referred to as a downlink (DL), and the link from the first device 110 to the second device 120 is referred to as an uplink (UL). In the DL, the second device 120 is a transmission (TX) device (or transmitter), and the first device 110 is a reception (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver).

[0104] The communication in the communication environment 100 may be implemented according to any suitable communication protocol, including but not limited to cellular communication protocols of the first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), sixth generation (6G), etc., wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, etc., and / or any other protocol currently known or developed in the future. In addition, the communication may utilize any suitable wireless communication technology, including but not limited to: code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplex (FDD), time division duplex (TDD), multiple input multiple output (MIMO), orthogonal frequency division multiple access (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM) and / or any other technology currently known or developed in the future. How it works and example signaling used for communication

[0105] In the following, reference will be made to Figures 1 to 6 More details on what to do after a positioning measurement (e.g. GNSS) is completed / at the end of a measurement gap are discussed. For the purposes of this discussion, reference will be made to Figure 1 discuss Figures 1 to 6 , for example, by using the first device 110 , the second device 120 , the third device 125 , the cell 130 , and the cell 140 .

[0106] exist Figures 1 to 6 In the example of , the first device 110 can be used as a terminal device and the second device 120 can be used as a network device.

[0107] It should be understood that the operations at the first device 110 and the second device 120 should be coordinated. In other words, the second device 120 and the first device 110 should have a common understanding of configurations, parameters, etc. This common understanding can be achieved through any suitable interaction or by applying the same rules / policies.

[0108] In the following, although some operations are described from the perspective of the first device 110, it should be understood that the corresponding operations should be performed by the second device 120. Similarly, although some operations are described from the perspective of the second device 120, it should be understood that the corresponding operations should be performed by the first device 110. For the sake of brevity, some of the same or similar contents are omitted here.

[0109] Additionally, in the following description, examples of message types (such as "RRC message", "MAC CE", "DCI") are only used for illustrative purposes and do not imply any limitation. In other example embodiments, any suitable message type can be used for the interaction between the first device 110 and the second device 120.

[0110] In the following, the behavior of the UE / network is discussed in particular for the following scenarios: the UE is configured with GNSS measurement gaps and the UE is also configured with other measurements, such as RLM / RRM, or when the UE performs GNSS measurements during the GNSS measurement gaps, the UE suspends certain AS operations (e.g., SR, BSR, RACH, TAT timer).

[0111] Hereinafter, the positioning measurement completion time refers to the actual time when the first device 110 completes the positioning measurement. The positioning measurement completion time may be shorter than the allocated / configured GNSS measurement gap.

[0112] Reference now Figure 2 , which shows a signaling diagram 200 for communication according to some example embodiments of the present disclosure.

[0113] In operation, in order to ensure that the following operations are more reasonable at the technical level, in some example embodiments, the first device 110 may determine the relationship between the completion time of the positioning measurement (less than the measurement gap) and the available time of the serving cell (e.g., cell 130) of the first device 110, and / or determine the first time length of the duration for performing the positioning measurement and the second time length of the valid duration of the uplink synchronization parameter in the serving cell (wherein the first time length is shorter than the third time length of the positioning measurement gap). Based on this relationship, the following operations can be performed more reasonably at the technical level.

[0114] It should be noted that the relationship can be determined based on one or more of the following: 1) an association between the completion time of the positioning measurement and the available time of the serving cell of the first device 110; 2) an association between a first time length of the duration for performing the positioning measurement and a second time length of the valid duration of the uplink synchronization parameter in the serving cell; and 3) other suitable associations. In short, the relationship can be determined based on multiple factors. The present disclosure is not limited in this regard.

[0115] like Figure 2 As shown, the first device 110 performs 230 a positioning measurement, and after the positioning measurement is completed, the first device 110 performs 240 at least one of the following based on the relationship: Skipping a radio link failure (RLF) procedure in a serving cell (e.g., cell 130); Performing a reestablishment process with a target cell (e.g., cell 140); Execute cell reselection process; stopping at least one access stratum (AS) operation suspended due to performing positioning measurements; Performing mobility-related procedures (e.g., CHO based on location trigger. For example, the first device 110 may have obtained a new location (via positioning measurements) and performs CHO based on a pre-configured location trigger); Starting to perform at least one mobility measurement or positioning reference signal (PRS) measurement, a duration for performing the at least one mobility measurement or PRS measurement at least partially overlapping with a duration for performing the positioning measurement; or At least one AS operation that was suspended due to performing positioning measurements is resumed.

[0116] Therefore, the second device 120 also needs to determine a similar relationship. In some embodiments, the second device 120 may determine 250 a relationship between at least one of the following: a completion time of the first device 110 completing the positioning measurement and an available time of the serving cell of the first device 110 provided by the second device 120, or a first time length of a duration for performing the positioning measurement by the first device 110 and a second time length of a valid duration of an uplink synchronization parameter in the serving cell.

[0117] It should be noted that, although the second device 120 may not be able to determine / monitor / know the time when the first device 110 actually completes the positioning measurement, the second device 120 can estimate the completion time of the first device 110 completing the positioning measurement (or the first time length for the duration of the positioning measurement performed by the first device 110). In this case, the second device 120 can predict / estimate / expect that the first device 110 has completed the positioning measurement. With this prediction / estimation / expectation, the second device 120 can be consistent with the first device 110. The details of how to predict / estimate / expect that the first device 110 has completed the positioning measurement may depend on the network implementation.

[0118] In some example embodiments, the first device 110 / the second device 120 may determine the available time of the serving cell based on at least one of the following: The service time of the second device 120 providing the service cell, for example, t service for a terrestrial fixed cell, satellite assistance information of the second device 120, the location of the first device 110, The reference point of the serving cell; or The coverage area of ​​the service cell.

[0119] In some example embodiments, the valid duration of the uplink synchronization parameter may be defined as a default value. As an example, the valid duration is predefined by a communication organization (such as 3GPP), or is predefined by a network operator or service provider. In this way, no additional signaling exchange is required between the first device 110 and the second device 120.

[0120] Alternatively, in some example embodiments, the valid duration may be dynamically or semi-statically configured. For example, the first device 110 and the second device 120 may determine the valid duration and then notify the other device of the valid duration.

[0121] In some example embodiments, the synchronization threshold (ie, the validity duration of the uplink synchronization parameter) may be a UE-specific value that defines the time the UE can maintain serving cell synchronization without performing any serving cell measurements.

[0122] In some example embodiments, the first device 110 may report the value of such a synchronization threshold as a UE capability. Alternatively, the synchronization threshold may be configured by the second device 120.

[0123] In the following, we will discuss in detail how to operate based on this relationship.

[0124] In some example embodiments, if the completion time of the positioning measurement is later than or equal to the available time of the serving cell, then after completion of the positioning measurement, the first device 110 may perform at least one of the following: skipping the RLF process in the serving cell, performing a reestablishment process with the target cell, performing a cell reselection process, or stopping at least one AS operation.

[0125] Alternatively or additionally, if the first time length is equal to or longer than the second time length, the first device may perform at least one of the following: skip the RLF process in the serving cell, perform a reestablishment process with the target cell, perform a cell reselection process, or stop at least one AS operation.

[0126] For better understanding, some example embodiments are discussed where GNSS measurements are used as examples of positioning measurements.

[0127] In some example embodiments, first device 110 may compare the GNSS measurement completion time and the serving cell available time. If the GNSS measurement completion time exceeds the serving cell available time, first device 110 may perform an RRC reestablishment (or cell reselection) process after the GNSS measurement is completed.

[0128] Alternatively or additionally, if the GNSS measurement completion time exceeds the serving cell available time, the first device 110 may skip the RLF procedure in the serving cell.

[0129] Alternatively or additionally, if the GNSS measurement completion time exceeds the serving cell available time, the first device 110 may stop the suspended AS operation after the GNSS measurement is completed.

[0130] In some example embodiments, the cell available time may be determined based on a t service for an earth-fixed cell or based on satellite assistance information for an earth-mobile cell (eg, a distance between the location of the first device 110 and a cell reference point exceeds a threshold).

[0131] Alternatively, the first device 110 compares the GNSS measurement time length (i.e., the first time length of the duration for performing positioning measurements) and the synchronization threshold (i.e., the second time length of the valid duration of the uplink synchronization parameter). If the GNSS measurement time length exceeds the synchronization threshold, the first device 110 may perform an RRC reestablishment (or cell reselection) process after the GNSS measurement is completed.

[0132] Alternatively or additionally, if the GNSS measurement time length exceeds the synchronization threshold, the first device 110 may skip the RLF procedure in the serving cell.

[0133] Alternatively or additionally, if the GNSS measurement time length exceeds the synchronization threshold, the first device 110 may stop the suspended AS operation after the GNSS measurement is completed.

[0134] In some example embodiments, the second device may assist the first device 110 in connecting to the next cell. For example, the serving cell may provide the UE context to the target cell, and the target cell may provide contention-free random access resources / PRACH and configured C-RNTI / RACH-free access resources via the serving cell.

[0135] In some example embodiments, the first device 110 may receive a third message from the second device 120, and the third message may indicate at least one of the following: The target cell’s contention-free random access channel (RACH) resources, RACH-free access resources of the target cell, or The cell radio network temporary identifier C-RNTI is used for physical random access channel PRACH transmission on the target cell.

[0136] In some example embodiments, the network may also provide the target cell with relevant satellite ephemeris (eg, future ephemeris valid when the GNSS MG is completed). The configuration / information may be provided as part of or together with the GNSS MG trigger.

[0137] In some embodiments, the second device 120 may also provide a parameter of t-serviceStart (which indicates when the target cell will start serving the area for the geostationary cell).

[0138] In some example embodiments, if the completion time of the positioning measurement is earlier than or equal to the availability time of the serving cell, then after the completion of the positioning measurement, the first device 110 may perform at least one of the following: start performing at least one mobility measurement or PRS measurement, perform a mobility-related process (e.g., CHO based on location triggering. For example, the first device 110 may obtain a new location (via positioning measurement) and perform CHO based on a preconfigured location trigger), or resume at least one AS operation.

[0139] Alternatively or additionally, if the first time length is longer than or equal to the second time length, after completion of the positioning measurement, the first device 110 may perform at least one of the following: start performing at least one mobility measurement or PRS measurement, perform mobility-related procedures, or resume at least one AS operation.

[0140] In some example embodiments, the first device 110 may extend or shift a duration for performing at least one mobility measurement or PRS measurement.

[0141] In some example embodiments, after completion of at least one mobility measurement or PRS measurement, the first device 110 may transmit information indicating a remaining positioning valid duration to the second device 120 .

[0142] In some example embodiments, the first device 110 may transmit a notification to the second device 120, the notification indicating at least one of the following: at least one mobility measurement is shifted to the completion of the positioning measurement, a duration for performing at least one mobility measurement is extended, the number of at least one mobility measurement, or Time information required for performing at least one mobility measurement.

[0143] In some example embodiments, after a GNSS measurement gap, the first device 110 may inform the second device 120 (as a UE capability) about the number of RLM / RRM measurements it needs to perform / the time required to perform these measurements. The second device 120 may then shift / extend these gaps accordingly.

[0144] In some example embodiments, the first device 110 may optionally report a GNSS position fix duration, which also allows the first device 110 to perform mobility measurements during the duration (UE implementation).

[0145] In some example embodiments, the (GNSS) position fix duration reported by the first device 110 (e.g., UE) may be longer than the duration actually required by the first device 110 (e.g., UE). Therefore, the first device 110 (e.g., UE) may perform mobility measurements during the difference between the actual required duration and the reported position fix duration.

[0146] In some example embodiments, the first device 110 may transmit 220 a first message to the second device 120, and the first message may indicate at least one of the following: a first positioning position fix time duration and an additional duration for performing at least one mobility measurement or a PRS measurement, or A second position fix time duration is determined based at least in part on an additional time duration for performing at least one mobility measurement or a PRS measurement.

[0147] In some example embodiments, second device 120 may receive 210 a second message from second device 120, the second message may indicate at least one of the following: a first indication indicating that the first device is allowed to perform at least one mobility measurement or PRS measurement after completion of the positioning measurement, at least one parameter indicating an additional duration for performing at least one mobility measurement or PRS measurement, or The extended time length of the configured positioning measurement gap.

[0148] For better understanding, some example embodiments are discussed where GNSS measurements are used as examples of positioning measurements.

[0149] In some example embodiments, if the GNSS measurement completion time does not exceed the serving cell available time and / or the GNSS measurement time length does not exceed the synchronization threshold, the first device 110 may resume the suspended AS operation after the GNSS measurement is completed.

[0150] In addition, the first device 110 may still encounter GNSS measurements (gaps) that conflict with RLM and / or RRM measurements. In this case, the first device 110 may evaluate whether these mobility measurements require measurement gaps. If so, the first device 110 may need to shift the mobility measurement gaps to after the completion of the GNSS measurements.

[0151] In some example embodiments, if the mobility measurement gap is extended to exceed the GNSS measurement gap duration (assuming that the first device 110 completes the GNSS measurement before the GNSS measurement gap ends), the first device 110 may notify the second device 120 about the shift. Otherwise, the first device 110 may autonomously perform the mobility measurement before reporting the GNSS valid duration to indicate that the GNSS measurement is successful.

[0152] In some example embodiments, second device 120 may also indicate as part of a GNSS measurement gap configuration or a GNSS measurement trigger that first device 110 is allowed to perform mobility measurements after the GNSS measurement. For example, second device 120 may configure the number of additional mobility measurement gaps or the extended time length of the measurement gaps.

[0153] According to some embodiments, the operation at the first device 110 may be controlled by the second device 120, which will refer to Figure 3 Have a discussion. Figure 3 A signaling diagram 300 for communication according to some example embodiments of the present disclosure is shown.

[0154] In operation, the second device 120 may determine 310 a relationship between a completion time of the positioning measurement and an available time of the serving cell of the first device 110. Alternatively or additionally, the second device 120 may determine 310 a relationship between a first time length of the positioning measurement and a second time length of a valid duration of an uplink synchronization parameter in the serving cell.

[0155] Then, if the completion time of the positioning measurement is later than or equal to the service availability time, and / or the first time length is equal to or longer than the second time length, the second device 120 may transmit 320 a fourth message for releasing the first device 110 to the idle state.

[0156] In some embodiments, the fourth message indicates at least one of the following: a positioning-related reason indicating that the first device is performing positioning measurements; or A target cell or candidate cell for the first device.

[0157] like Figure 3 As shown, after receiving the fourth message, the first device 110 can transition 330 to an idle state.

[0158] Furthermore, in some example embodiments, after receiving the fourth message, the first device 110 may perform 340 positioning measurements after receiving the fourth message.

[0159] In the case of non-continuous coverage NTN, the target cell (i.e., the next serving cell) may be far away from the current serving cell. In this case, when the first device 110 approaches the target cell, the first device 110 may start to perform positioning measurements. In some example embodiments, the first device 110 may determine the time point for performing positioning measurements based on the available time of the target cell. In this way, power consumption for performing unnecessary positioning measurements can be avoided.

[0160] In some example embodiments, the first device 110 may compare the GNSS measurement completion time and the serving cell available time. If the GNSS measurement completion time exceeds the serving cell available time, the second device 120 may skip the GNSS measurement trigger and release the first device 110 to RRC idle with the reason being "performing GNSS measurement" and, if the physical cell identity (PCI) is unknown in this state, indicate the target cell identity (e.g., PCI) or at least the frequency layer / resource / band of the target cell.

[0161] According to some embodiments, the CHO process can be further improved. Figure 4 , which shows a signaling diagram 400 for communication according to some example embodiments of the present disclosure.

[0162] like Figure 4 As shown, the serving cell 130 and the candidate cell 140 may determine 405 resources to be used by the first device 110 to perform CHO on the candidate cell 140 .

[0163] The serving cell 130 may then transmit 410 the CHO configuration of the candidate cell 140 to the first device 110. In addition, the CHO configuration may indicate resources for performing CHO on the candidate cell 140.

[0164] In the conventional CHO process, with this CHO configuration, the first device 110 can perform a CHO execution evaluation and be triggered to switch to the candidate cell 140 when the CHO condition is met. However, in the case where the positioning measurement conflicts with the CHO execution evaluation, the CHO execution evaluation may be suspended. If so, the resources previously configured for performing CHO on the candidate cell 140 may become invalid. The above problem can be solved through the following discussion.

[0165] like Figure 4 As shown, the first device 110 can perform 430 a positioning measurement that conflicts with the CHO execution evaluation on the candidate cell, and can start 440 the CHO execution evaluation after the positioning measurement is completed or after the positioning measurement gap of the positioning measurement ends. Hereinafter, the first device 110 can access 450 the candidate cell 140 by using the post-switching resources.

[0166] To ensure that the candidate cell 140 can also provide resources after switching. Figure 4 As shown, based on determining that the positioning measurement at the first device 110 conflicts with the CHO execution evaluation on the candidate cell 140, the serving cell 130 may transmit 420 a fifth message to the candidate cell 140, wherein the fifth message indicates that the candidate cell shifts resources to be used for performing CHO on the candidate cell.

[0167] In addition, whether to allow exchange of resources can be enabled on demand.

[0168] In some embodiments, in the case where the serving cell 130 determines that the positioning measurement (e.g., UE GNSS) and the CHO conflict, the serving cell 130 may need to ask the candidate cell 140 whether the resources can be shifted by transmitting a fifth message to the candidate cell 140, the fifth message requesting the candidate cell 140 to shift the resources. Optionally, the candidate cell 140 may transmit 425 a response to the serving cell 130 indicating that the resources can be shifted. In the case, the serving cell 130 may transmit a second indication to the first device 110, the second indication indicating that the first device is allowed to shift the start of the CHO execution evaluation.

[0169] Alternatively, in some embodiments, serving cell 130 may transmit a second indication to first device 110, the second indication indicating that the first device is allowed to shift the start of the CHO performance evaluation. In some example embodiments, the second indication may be included in the CHO configuration.

[0170] Additionally, the fifth message may be transmitted to the candidate cell 140 under the condition of the second indication.

[0171] For better understanding, some example embodiments are discussed where GNSS measurements are used as examples of positioning measurements.

[0172] In some example embodiments, in the case of enhanced machine type communication (eMTC), when conditional handover is prepared and GNSS measurements start, the serving node may notify the target node to extend the retention time to allow the UE to perform a deferred CHO execution evaluation and complete the conditional handover. In some embodiments, CHO may be performed based on location, time and / or radio measurements, and in the case of long GNSS measurements, all types of evaluations (and / or CHO executions) will be delayed.

[0173] In some example embodiments, the first device 110 may be implicitly aware of the reserved shifts, or the CHO configuration may define whether such shifts are allowed or not allowed in case of conflict with GNSS measurements.

[0174] According to some embodiments, the C-DRX scenario can be further improved. Figure 5 , which shows a signaling diagram 500 for communication according to some example embodiments of the present disclosure.

[0175] In some example embodiments, the second device 120 may transmit 510 to the first device 110 a C-DRX configuration indicating at least one activity duration. Figure 5 In the embodiment of the present invention, the first device 110 may perform 520 positioning measurements.

[0176] Hereinafter, for the first device 110 , in response to at least one activity duration overlapping with a positioning measurement gap, the first device 110 may wake up 530 at the end of the measurement gap to monitor control information indicating at least one pending transmission of the first device.

[0177] Thus, in some example embodiments, for the second device 120, in response to the activity duration of at least one activity duration overlapping with the positioning measurement gap, the second device 120 may transmit control information at the end of the measurement gap of the positioning measurement, the control information indicating at least one pending transmission of the first device.

[0178] like Figure 5 As shown, the first device may wake up during T2 (eg, exit C-DRX mode) and may monitor control information during T2. In some example embodiments, T2 may be a configured / default ON duration or a configured / default wake-up duration.

[0179] In some example embodiments, second device 120 may transmit a configuration to first device 120 that may indicate at least one of the following: a third indication indicating that the first device is allowed to wake up at the end of the measurement gap, or an ON duration (e.g., T2) after the measurement gap.

[0180] For better understanding, some example embodiments are discussed where GNSS measurements are used as examples of positioning measurements.

[0181] In some example embodiments, if the DRX ON duration overlaps with a GNSS measurement gap, the first device 110 may be configured to exit C-DRX at the end of the GNSS measurement gap to check for any pending transmissions within the overlapping ON duration. In some example embodiments, the second device 120 may configure the first device 110 to wake up for a (short) ON duration after a GNSS measurement gap in addition to a normal C-DRX configuration.

[0182] According to some embodiments, the mobility measurement can be further improved. Figure 6 , which shows a signaling diagram 600 for communication according to some example embodiments of the present disclosure.

[0183] In operation, the first device 110 receives 610 from the second device 120 a measurement configuration for configuring mobility measurement of a neighboring cell (eg, the cell 140 ).

[0184] Hereinafter, the first device 110 may perform 620 a positioning measurement that conflicts with a mobility measurement of a neighboring cell. The first device 110 may relax 630 a requirement for the mobility measurement of the neighboring cell.

[0185] In addition, the relaxation process may be controlled / configured by the second device 120 / serving cell 130. Specifically, in some example embodiments, the first device 110 may receive a sixth message from the second device 120, the sixth message indicating at least one of the following: a fourth indication, indicating that if the mobility measurement conflicts with the positioning measurement, the first device is allowed to relax the requirement for the mobility measurement of the neighboring cell; or At least one parameter used to relax the requirement.

[0186] For better understanding, some example embodiments are discussed where GNSS measurements are used as examples of positioning measurements.

[0187] In some example embodiments, the second device 120 may indicate to the first device 110 that the first device 110 is allowed to relax RLM / RRM measurement requirements, such as the time required to evaluate a target cell, when the measurement conflicts with a GNSS measurement gap. In some example embodiments, the indication may be provided in a GNSS or mobility measurement configuration.

[0188] With the above process, the UE can better handle long GNSS position fix durations, especially when GNSS measurement gaps conflict with RLM / RRM measurements. Example Method
