AI Technical Summary
In new radio non-terrestrial networks, user equipment cannot operate IoT NTN simultaneously while performing GNSS measurements, leading to communication interruptions and increased power consumption. Existing technologies have failed to effectively address the recovery and conflict issues of RRM/RLM/AS operations during GNSS measurement intervals.
By determining the relationship between the completion time of positioning measurements and the availability time of the serving cell, RRM/RLM/AS activities can be adjusted to optimize the behavior of terminal and network devices during GNSS measurement gaps, avoiding unnecessary power consumption and reducing communication interruptions.
Effectively manage RRM/RLM/AS activities during GNSS measurement gaps to reduce unnecessary power consumption, minimize communication interruptions, and improve system efficiency.

Abstract
Description
Technical Field
[0001] Various exemplary embodiments of this disclosure generally relate to the telecommunications field, and more specifically, to methods, apparatus, devices, and computer-readable storage media for processing positioning measurements. Background Technology
[0002] In New Radio (NR) Non-Terrestrial Networks (NTNs), it is assumed that User Equipment (UE) always has the capability for Global Navigation Satellite System (GNSS) measurements and will determine its location based on the measured GNSS information. Further discussion below will focus on supporting the Internet of Things (IoT) over NTNs. The 3GPP (3rd Generation Partnership Project) assumes that UEs cannot operate both GNSS and IoT NTNs simultaneously; therefore, Radio Access Network Working Groups (WG) 1 (RAN1) and RAN WG2 (RAN2) specify GNSS measurement gaps during which UEs can perform GNSS measurements without monitoring the Physical Downlink Control Channel (PDCCH) and performing other “3GPP tasks.”

[0063] As used in this application, the term "circuit system" may refer to one or more or all of the following:
[0064] (a) Hardware circuit implementation only (such as implementation in analog only and / or implementation in digital circuit only), and

Embodiments of this disclosure are applicable to a variety of communication systems. Given the rapid development of communications, there are, of course, future types of communication technologies and systems that can implement this disclosure. This disclosure should not be construed as limiting its scope to the systems described above.
[0071] As used herein, the term "network device" refers to a node in a communication network through which a terminal device accesses and receives services. Network devices can refer to base stations (BS) or access points (APs), such as Node B (NodeB or NB), evolved Node B (eNodeB or eNB), NR NB (also known as gNB), Remote Radio Unit (RRU), Radio Head (RH), Remote Radio Head (RRH), repeaters, Integrated Access and Backhaul (IAB) nodes, low-power nodes such as femtoseconds, picoseconds, non-terrestrial network (NTN) or non-terrestrial network devices (such as satellite network devices, low Earth orbit (LEO) satellites and geostationary orbit (GEO) satellites, aircraft network devices, etc.), depending on the terminology and technology applied. In some example embodiments, the Radio Access Network (RAN) split architecture includes a centralized unit (CU) and a distributed unit (DU) at the IAB donor node. The IAB node includes a mobile terminal (IAB-MT) portion that behaves similarly to a UE toward its parent node, while the DU portion of the IAB node behaves similarly to a base station toward the next-hop IAB node.
[0072] The term "terminal device" refers to any end device capable of wireless communication. By way of example and not limitation, a terminal device may also be referred to as a communication device, user equipment (UE), subscriber station (SS), portable subscriber station, mobile station (MS), or access terminal (AT). Terminal devices can include, but are not limited to, mobile phones, cellular phones, smartphones, Voice over IP (VoIP) phones, wireless local loop phones, tablet computers, wearable terminal devices, personal digital assistants (PDAs), portable computers, desktop computers, image capture terminal devices such as digital cameras, gaming terminal devices, music storage and playback facilities, in-vehicle wireless terminal devices, wireless endpoints, mobile stations, laptop embedded devices (LEEs), laptop mounted devices (LMEs), USB dongles, smart devices, wireless subscriber equipment (CPEs), Internet of Things (IoT) devices, watches or other wearable devices, head-mounted displays (HMDs), vehicles, drones, medical devices and applications (e.g., remote surgery), industrial devices and applications (e.g., robots and / or other wireless devices operating in industrial and / or automated processing chain environments), consumer electronics devices, devices operating on commercial and / or industrial wireless networks, etc. The terminal device may also correspond to the mobile terminal (MT) portion of an IAB node (e.g., a relay node). In the following description, the terms "terminal device," "communication device," "terminal," "user equipment," and "UE" are used interchangeably.
[0073] As used herein, the terms “resource,” “transmission resource,” “resource block,” “physical resource block” (PRB), “uplink resource,” or “downlink resource” can refer to any resource used to perform communication (e.g., communication between a terminal device and a network device), such as resources in the time domain, resources in the frequency domain, resources in the spatial domain, resources in the code domain, or any other combination of time-domain, frequency-domain, spatial-domain, and / or code-domain resources for implementing communication. In the following, unless explicitly stated otherwise, resources in the frequency and time domains will be used as examples of transmission resources used to describe some exemplary embodiments of this disclosure. It should be noted that the exemplary embodiments of this disclosure are equally applicable to other resources in other domains.
[0074] As mentioned above, in NR NTN, IoT NTN or other types of NTN, it is assumed that the UE always has the ability to measure GNSS and will realize its location based on the measured GNSS information.
[0075] In some example implementations, GNSS can be used by the UE to determine its location, allowing the UE to compensate for radio propagation between the UE and the satellite. For geostationary 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 caused by satellite movement (approximately 7.5 km / s relative to Earth).
[0076] In this disclosure, GNSS measurements can be triggered by network devices or UEs.
[0077] Specifically, in some example embodiments, the network device can trigger the UE to perform GNSS measurements during scheduled intervals. Additionally, in some example embodiments, the network device can at least support triggering the UE to perform GNSS measurements aperiodically. In the case of aperiodic triggering, the network device can use a Media Access Control (MAC) control element (CE) or Radio Resource Control (RRC) signaling to trigger the UE to perform GNSS measurements. Triggering by the network device is expected to be based on the reported effective GNSS duration. When the UE is in connected mode, the UE can utilize the MAC CE to report the effective GNSS duration. Additionally, in some example embodiments, the UE is also required to report a “GNSS location fixed duration” (i.e., the time required for the UE to perform GNSS measurements) at least during the initial access phase. The parameter “GNSS location fixed duration” can be used by the network device to determine the length of the GNSS measurement interval. In some example embodiments, a new downlink MAC CE can be introduced to trigger the connected UE to perform GNSS measurements.
[0078] In some example implementations, for GNSS measurements in the connected Radio Resource Control (RRC), if the network device non-periodically triggers the connected UE to perform GNSS measurements, the UE can reacquire GNSS location information with gaps.
[0079] In some example embodiments, the duration of a GNSS measurement gap triggered non-periodically via the MAC CE can be configured by the eNB. Additionally, when the duration of the GNSS measurement gap is not included in the eNB's configuration, the gap duration is equal to the most recently reported fixed duration of the GNSS position used for measurement.
[0080] In some example implementations, if the UE does not receive a trigger for GNSS measurement from the network device, the UE can autonomously perform GNSS measurement. In this case, the network device and the UE should have a common understanding regarding when and how to initiate GNSS measurement. As a specific embodiment, when the UE is not available for scheduling during the GNSS measurement period, the UE can autonomously perform GNSS measurement when the effective GNSS duration expires.
[0081] As a specific implementation, for GNSS measurements under RRC connections, if the network device non-periodically triggers a connected UE to perform GNSS measurements. Furthermore, when configured to autonomously trigger GNSS measurements, if the UE does not receive a trigger from the network device to perform GNSS measurements, the UE can autonomously reacquire GNSS data.
[0082] In some example embodiments, from RAN1's perspective, at least for cases where the frequency and timing errors are within the frequency and timing error requirements using conventional closed-loop time correction, uplink transmission can be allowed for a duration X after the original GNSS effective duration expires without reacquiring GNSS.
[0083] In some example implementations, the UE is not required to transmit or receive any channels / signals during the duration of the non-periodic GNSS measurement gap until it successfully reacquires GNSS.
[0084] In some example embodiments, the UE can report a fixed duration of GNSS position for a single GNSS measurement via a 4-bit field having component values [1, 2, 3, 4, 5, 6, 7, 13, 19, 25, 31, 6*n+1, ...].
[0085] In some example implementations, the GNSS effective duration reported by the UE may be the remaining effective duration.
[0086] In some example embodiments, the UE can trigger a GNSS measurement report after each GNSS fixing operation is completed.
[0087] It can be seen that the eNB can trigger GNSS measurement gaps (MG) non-periodically, during which the UE can perform measurements, and this triggering can be based on downlink MAC CE, and the network is free to decide when to trigger GNSS measurements.
[0088] Furthermore, if the UE does not receive a non-periodic trigger and if the UE is configured with this autonomous GNSS MG configuration, the UE can autonomously reacquire GNSS. Additionally, the UE can report the remaining valid duration for the GNSS validity period upon completion of GNSS fixing. This allows the UE and eNB to have a shared understanding of the UE's GNSS status, i.e., when it is valid and when it has expired.
[0089] As mentioned above, 3GPP assumes that the UE cannot operate GNSS and IoT NTN simultaneously. Therefore, 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." Furthermore, it is anticipated that improved GNSS operation will be studied and specified in the following areas: new location fixation for UE pre-compensation during long connection times and reduced power consumption.
[0090] In some embodiments, radio link management (RLM) can be paused during GNSS measurement intervals while the UE is measuring GNSS. Furthermore, it is not expected that the UE will acquire system information and GNSS location simultaneously. If the UE cannot acquire System Information Block 31 (SIB 31) before the start of the GNSS measurement interval, the acquisition of SIB 31 can be postponed until the GNSS measurement is completed.
[0091] In some example implementations, certain operations can be stopped / paused when the UE measures GNSS during GNSS MG. Example operations include, but are not limited to: the dataInactivityTimer can be stopped; the execution of a Conditional Handover (CHO) can be postponed; RLM-related timers can be stopped (e.g., timers related to RLF and rebuild (e.g., T310, T311, and T301) should be paused; T310 can be paused; T310 can be extended); Time Alignment Timer (TAT) processing can be paused / stopped (e.g., timeAlignmentTimer expires, TAT is paused); unnecessary neighbor cell measurements should be avoided during the duration of the GNSS measurement; Random Access Channel (RACH) / Schedule Request (SR) / Buffer Status Report (BSR) can be paused.
[0092] To date, while some discussions and agreements have been reached regarding UE / network behavior, many issues remain to be addressed. For example, an agreement has been reached that certain AS operations should be suspended when a UE performs GNSS measurements during GNSS measurement intervals. However, whether suspended AS operations should be resumed when the UE completes GNSS measurements has not yet been discussed.
[0093] Another issue to be addressed is that while it has been agreed to suspend RLM during GNSS MG, the impact on RRM measurements has not been defined, nor has it been defined how the UE should "recover" from the missing RLM measurements. Yet another issue to be addressed is that RRM measurements that conflict with GNSS MG have not been discussed.
[0094] Furthermore, it has been agreed that the UE does not need to transmit or receive during GNSS measurement gaps, and the fixed duration of the GNSS location used by the network to configure GNSS measurement gaps is within 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 long period of time (up to 31 seconds or even more). In this case, normal mobility activities can be affected. Moreover, it is unclear whether AS operations should be resumed / continued when the UE completes GNSS measurements if they are paused during GNSS MG (GNSS measurement interval).
[0095] Therefore, how to regulate the behavior of terminal equipment and network equipment during GNSS measurement gaps needs to be discussed.
[0096] According to some exemplary embodiments of this disclosure, a solution is provided for defining the behavior of terminal devices and network devices in discontinuous coverage. In this solution, a first device (e.g., a terminal device) can determine a relationship between the completion time of a positioning measurement (e.g., GNSS measurement or positioning measurement based on 3GPP signaling) and the availability time of the serving cell of the first device, or determine a first time length for the duration of performing the positioning measurement and a second time length for the effective duration of uplink synchronization parameters in the serving cell. Then, based on the determined relationship, RRM / RLM / AS activities can be appropriately processed.
[0097] In summary, since RRM / RLM / AS activities can be defined after GNSS measurements are completed, unnecessary power consumption can be avoided and communication interruptions can be minimized.

Note that the example embodiments described with respect to satellites are equally applicable to other types of network devices. This disclosure is not limited in this respect.
[0103] Example Environment
[0104] Figure 1 An example communication environment 100 in which exemplary embodiments of the present disclosure can be implemented is shown. In the communication environment 100, a plurality of communication devices, including a first device 110 and a second device 120, can communicate with each other.
[0105] exist Figure 1 In the example, 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 cell 130. It should be understood that the second device 120 may be deployed within or outside cell 130 depending on different needs and scenarios.
[0106] In some example embodiments, the communication environment 100 is an NTN network comprising one or more satellites. In some example embodiments, access network equipment (such as a gNB) may be deployed at the satellite (also known 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 known as a transparent architecture. In this disclosure, either or both of the satellite and the access network equipment may be considered as a second device 120, depending on the specific application scenario or requirement. This disclosure is not limited in this respect.
[0107] Additionally, in some example embodiments, either or both of the first device 110 and the second device 120 may move over time, which could cause the positional relationship between the first device 110, the second device 120 and the cell 130 to change.
[0108] like Figure 1 As shown, cell 140 can be a neighboring cell, candidate cell, or target cell of the first device. In some example embodiments, cell 140 can be provided by a third device 125.
[0109] In the following description, for illustrative purposes, some exemplary embodiments are depicted in which the first device 110 operates as a terminal device and the second device 120 operates as a network device. However, in some exemplary embodiments, the operations described in connection with the terminal device can be implemented at the network device or other devices, and the operations described in connection with the network device can be implemented at the terminal device or other devices.
[0110] 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 transmitting (TX) device (or transmitter), and the first device 110 is a receiving (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).
[0111] Communication in communication environment 100 can be implemented according to any suitable communication protocol, including but not limited to cellular communication protocols such as first-generation (1G), second-generation (2G), third-generation (3G), fourth-generation (4G), fifth-generation (5G), and sixth-generation (6G), wireless local area network communication protocols such as IEEE 802.11, and / or any other currently known or future-developed protocols. Furthermore, communication can 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 Extended OFDM (DFT-s-OFDM), and / or any other currently known or future-developed technologies.
[0112] Working principle and example signaling used for communication
[0113] In the following text, reference will be made to Figures 1 to 6 This section discusses further details regarding the procedures following the completion of positioning measurements (such as GNSS) or the end of a measurement gap. For the purposes of this discussion, references will be made to... Figure 1 discuss Figures 1 to 6 Example signaling flows in the example, for instance, using first device 110, second device 120, third device 125, cell 130, and cell 140.
[0114] exist Figures 1 to 6 In the example, the first device 110 can be used as a terminal device, and the second device 120 can be used as a network device.
[0115] It should be understood that the operation of 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 the configuration, parameters, etc. This common understanding can be achieved through any appropriate interaction or by applying the same rules / policies.
[0116] In the following description, although some operations are presented from the perspective of the first device 110, it should be understood that the corresponding operations are performed by the second device 120. Similarly, although some operations are presented from the perspective of the second device 120, it should be understood that the corresponding operations are performed by the first device 110. For the sake of brevity, some identical or similar content is omitted here.
[0117] Additionally, in the following description, examples of message types (such as “RRC message,” “MAC CE,” “DCI”) are for illustrative purposes only and do not imply any limitation. In other example embodiments, any suitable message type may be used for interaction between the first device 110 and the second device 120.
[0118] The following discussion focuses on the behavior of the UE / network in the following scenarios: the UE is configured with GNSS measurement gaps and is also configured with other measurements, such as RLM / RRM, or the UE suspends certain AS operations (e.g., SR, BSR, RACH, TAT timers) when performing GNSS measurements during GNSS measurement gaps.
[0119] In the following text, the positioning measurement completion time refers to the actual time it takes for the first device 110 to complete the positioning measurement. The positioning measurement completion time may be shorter than the allocated / configured GNSS measurement gap.
[0120] Now for reference Figure 2 The diagram shows a signaling diagram 200 for communication according to some example embodiments of the present disclosure.
[0121] In practice, to ensure that the following operations are more technically reasonable, 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 availability time of the serving cell (e.g., cell 130) of the first device 110, and / or determine a first time length for the duration of performing the positioning measurement and a second time length for the effective duration of the uplink synchronization parameters in the serving cell (wherein the first time length is shorter than a third time length of the positioning measurement gap). Based on this relationship, the following operations can be performed more technically.
[0122] It should be noted that the relationship can be determined based on one or more of the following: 1) the correlation between the completion time of the positioning measurement and the availability time of the serving cell of the first device 110; 2) the correlation between a first time length for performing the positioning measurement and a second time length for the effective duration of the uplink synchronization parameters in the serving cell; and 3) other suitable correlations. In short, the relationship can be determined based on multiple factors. This disclosure is not limited in this respect.
[0123] like Figure 2 As shown, the first device 110 performs a positioning measurement (230), and after the positioning measurement is completed, the first device 110 performs at least one of the following (240) based on the relationship:
[0124] Skip the Radio Link Identification Failure (RLF) process in the serving cell (e.g., cell 130); Perform the reconstruction process for the target cell (e.g., cell 140);
[0125] Perform the cell reselection process;
[0126] Stop at least one access layer (AS) operation that was suspended due to the execution of positioning measurements;
[0127] Perform mobility-related processes (e.g., location-triggered CHOs. For example, the first device 110 may obtain a new location (via positioning measurements) and perform a CHO based on a pre-configured location trigger).
[0128] Initiate at least one mobility measurement or positioning reference signal (PRS) measurement, wherein the duration of performing the at least one mobility measurement or PRS measurement at least partially overlaps with the duration of performing the positioning measurement; or
[0129] Resume at least one AS operation that was suspended due to the execution of positioning measurements.
[0130] Therefore, the second device 120 also needs to determine a similar relationship. In some embodiments, the second device 120 may determine a relationship between at least one of the following: the completion time of the first device 110 completing the positioning measurement and the availability time of the serving cell of the first device 110 provided by the second device 120, or a first time length for the duration of the positioning measurement performed by the first device 110 and a second time length for the effective duration of the uplink synchronization parameters in the serving cell.
[0131] It should be noted that although the second device 120 may not be able to determine / monitor / know when the first device 110 actually completes the positioning measurement, the second device 120 can estimate the completion time of the positioning measurement by the first device 110 (or a 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. Using this prediction / estimate / expectation, the second device 120 can maintain alignment 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.
[0132] In some example embodiments, the first device 110 / second device 120 may determine the availability time of the serving cell based on at least one of the following:
[0133] Provide the service time of the second device 120 in the service cell, for example, the t service for a fixed Earth cell.
[0134] Satellite auxiliary information from the second device 120
[0135] The position of the first device 110
[0136] Reference points for serving the community; or
[0137] The service area covered by the community.
[0138] In some example embodiments, the effective duration of the uplink synchronization parameters can be defined as a default value. As an example, the effective duration is predefined by a communications organization (such as 3GPP) or 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.
[0139] Alternatively, in some example embodiments, the effective duration can be configured dynamically or semi-statically. For example, the first device 110 and the second device 120 can determine the effective duration and then notify the other device of the effective duration.
[0140] In some example implementations, the synchronization threshold (i.e., the effective duration of the uplink synchronization parameters) can be a UE-specific value that defines the time during which the UE can maintain serving cell synchronization without performing any serving cell measurements.
[0141] 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.
[0142] The following section will discuss in detail how to operate based on this relationship.
[0143] In some example embodiments, if the location measurement is completed later than or equal to the availability time of the serving cell, the first device 110 may perform at least one of the following after the location measurement is completed: skip the RLF process in the serving cell, perform a reconstruction process with the target cell, perform a cell reselection process, or stop at least one AS operation.
[0144] 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 procedure in the serving cell, perform a reconstruction procedure with the target cell, perform a cell reselection procedure, or stop at least one AS operation.
[0145] To better understand, some example implementations are discussed, in which GNSS measurements are used as examples of positioning measurements.
[0146] In some example embodiments, the first device 110 may compare the GNSS measurement completion time with the serving cell availability time. If the GNSS measurement completion time exceeds the serving cell availability time, the first device 110 may perform an RRC reconstruction (or cell reselection) procedure after the GNSS measurement is completed.
[0147] Alternatively or additionally, if the GNSS measurement completion time exceeds the serving cell availability time, the first device 110 may skip the RLF process in the serving cell.
[0148] Alternatively or additionally, if the GNSS measurement completion time exceeds the serving cell availability time, the first device 110 may stop the suspended AS operation after the GNSS measurement is completed.
[0149] In some example embodiments, cell availability time can be determined based on t services for fixed Earth cells or satellite-assisted information for mobile Earth cells (e.g., the distance between the location of the first device 110 and the cell reference point exceeds a threshold).
[0150] Alternatively, the first device 110 compares the GNSS measurement time length (i.e., a first time length for the duration of performing positioning measurements) with a synchronization threshold (i.e., a second time length for the effective duration of uplink synchronization parameters). If the GNSS measurement time length exceeds the synchronization threshold, the first device 110 may perform an RRC reconstruction (or cell reselection) process after the GNSS measurement is completed.
[0151] Alternatively or additionally, if the GNSS measurement time exceeds the synchronization threshold, the first device 110 may skip the RLF process in the serving cell.
[0152] Alternatively or additionally, if the GNSS measurement time exceeds the synchronization threshold, the first device 110 may stop the suspended AS operation after the GNSS measurement is completed.
[0153] 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.
[0154] In some example embodiments, the first device 110 may receive a third message from the second device 120, the third message indicating at least one of the following:
[0155] Contention-free random access channel (RACH) resources of the target cell.
[0156] RACH-free access resources of the target cell, or
[0157] Cell Radio Network Temporary Identifier (C-RNTI) used for Physical Random Access Channel (PRACH) transmission on the target cell.
[0158] In some example embodiments, the network may also provide the target cell with relevant satellite ephemeris (e.g., future ephemeris valid at the time of GNSS MG completion). Configuration / information may be provided as part of or together with the GNSS MG trigger.
[0159] In some embodiments, the second device 120 may also provide a t-serviceStart parameter (which indicates when the target cell will begin serving the area for a fixed Earth cell).
[0160] In some example embodiments, if the location measurement is completed earlier than or equal to the serving cell's availability time, the first device 110 may perform at least one of the following after the location measurement is completed: initiate at least one mobility measurement or PRS measurement, perform a mobility-related process (e.g., a location-triggered CHO; for example, the first device 110 may have obtained a new location (via location measurement) and perform a CHO based on a pre-configured location trigger), or resume at least one AS operation.
[0161] Alternatively or additionally, if the first time length is longer than or equal to the second time length, then after the positioning measurement is completed, the first device 110 may perform at least one of the following: initiate at least one mobility measurement or PRS measurement, perform a mobility-related process, or resume at least one AS operation.
[0162] In some example embodiments, the first device 110 may extend or shift the duration for performing at least one mobility measurement or PRS measurement.
[0163] In some example embodiments, after at least one mobility measurement or PRS measurement is completed, the first device 110 may transmit information to the second device 120 indicating the remaining effective duration of the positioning.
[0164] In some example embodiments, the first device 110 may transmit a notification to the second device 120 indicating at least one of the following:
[0165] At least one mobility measurement is shifted until the positioning measurement is completed.
[0166] The duration for performing at least one mobility measurement is extended.
[0167] The number of at least one mobility measurement, or
[0168] Time information required to perform at least one mobility measurement.
[0169] 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 and the time required to perform these measurements. The second device 120 may then shift / extend these gaps accordingly.
[0170] In some example embodiments, the first device 110 may optionally report a fixed duration of GNSS location, which also allows the first device 110 to perform mobility measurements (UE implementation scheme) during the duration.
[0171] In some example embodiments, the (GNSS) location fixation duration reported by the first device 110 (e.g., UE) may be longer than the actual duration 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 location fixation duration.
[0172] In some example embodiments, the first device 110 may transmit a first message 220 to the second device 120, the first message indicating at least one of the following:
[0173] The first positioning position is fixed for a fixed duration and an additional duration for performing at least one mobility measurement or PRS measurement, or
[0174] The duration of the second positioning fixation time is determined at least in part based on the additional duration used to perform at least one mobility measurement or PRS measurement.
[0175] In some example embodiments, the second device 120 may receive a second message 210, which may indicate at least one of the following:
[0176] The first instruction instructs the first device to perform at least one mobility measurement or PRS measurement after the positioning measurement is completed.
[0177] At least one parameter indicating the additional duration for performing at least one mobility measurement or PRS measurement, or
[0178] The extended time length of the configured positioning measurement gap.
[0179] To better understand, some example implementations are discussed, in which GNSS measurements are used as examples of positioning measurements.
[0180] In some example embodiments, if the GNSS measurement completion time does not exceed the serving cell availability time and / or the GNSS measurement duration does not exceed the synchronization threshold, the first device 110 can resume the suspended AS operation after the GNSS measurement is completed.
[0181] Furthermore, the first device 110 may still encounter conflicts between GNSS measurements (gap) and RLM and / or RRM measurements. In this case, the first device 110 can assess whether these mobility measurements require a measurement gap. If so, the first device 110 may need to reschedule the mobility measurement gap until after the GNSS measurements are completed.
[0182] In some example embodiments, if the mobility measurement gap extends beyond the duration of the GNSS measurement gap (assuming the first device 110 completes the GNSS measurement before the end of the GNSS measurement gap), the first device 110 may notify the second device 120 of this displacement. Otherwise, the first device 110 may autonomously perform the mobility measurement before reporting the effective GNSS duration to indicate successful GNSS measurement.
[0183] In some example embodiments, the second device 120 may also be used as part of a GNSS measurement gap configuration or GNSS measurement triggering to indicate that the first device 110 is permitted to perform mobility measurements after a GNSS measurement. For example, the second device 120 may be configured with an additional number of mobility measurement gaps or an extended duration of the measurement gaps.
[0184] According to some embodiments, the operation of the first device 110 can be controlled by the second device 120, which will refer to... Figure 3 Let's have a discussion. Figure 3 Signaling diagram 300 for communication is shown according to some example embodiments of the present disclosure.
[0185] In operation, the second device 120 can determine the relationship between the completion time of the 310 positioning measurement and the availability time of the serving cell of the first device 110. Alternatively or additionally, the second device 120 can determine the relationship between a first time length of the 310 positioning measurement and a second time length of the effective duration of the uplink synchronization parameters in the serving cell.
[0186] 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 a fourth message 320 to release the first device 110 into an idle state.
[0187] In some embodiments, the fourth message indicates at least one of the following:
[0188] The reason for instructing the first device to perform positioning measurements related to positioning; or
[0189] The target cell or candidate cell for the first device.
[0190] like Figure 3 As shown, after receiving the fourth message, the first device 110 can switch 330 to an idle state.
[0191] Furthermore, in some example embodiments, after receiving the fourth message, the first device 110 may perform a 340 positioning measurement.
[0192] In the case of discontinuous coverage NTN, the target cell (i.e., the next serving cell) may be far from the current serving cell. In this case, the first device 110 can begin performing location measurements when it approaches the target cell. In some example embodiments, the first device 110 can determine the timing of performing location measurements based on the availability time of the target cell. In this way, power consumption for performing unnecessary location measurements can be avoided.
[0193] In some example embodiments, the first device 110 may compare the GNSS measurement completion time with the serving cell availability time. If the GNSS measurement completion time exceeds the serving cell availability time, the second device 120 may skip the GNSS measurement trigger and release the first device 110 to RRC idle state under the condition of "performing GNSS measurement", and if the physical cell identifier (PCI) is unknown in this state, indicate the target cell identifier (e.g., PCI) or at least the frequency layer / resource / band of the target cell.
[0194] According to some embodiments, the CHO process can be further improved. See now for reference. Figure 4 The diagram shows a signaling diagram 400 for communication according to some example embodiments of the present disclosure.
[0195] like Figure 4 As shown, serving cell 130 and candidate cell 140 can determine 405 as the resources that the first device 110 will use to perform CHO on candidate cell 140.
[0196] Then, serving cell 130 can transmit the CHO configuration of candidate cell 140 to first device 110. In addition, the CHO configuration can indicate the resources used to perform CHO on candidate cell 140.
[0197] In a conventional CHO process, using this CHO configuration, the first device 110 can perform a CHO execution evaluation and be triggered to switch to candidate cell 140 when the CHO conditions are met. However, in the event of a conflict between positioning measurements and the CHO execution evaluation, the CHO execution evaluation may be suspended. If this happens, the resources previously configured for performing CHO on candidate cell 140 may become invalid. The above problem can be resolved through the following discussion.
[0198] like Figure 4 As shown, the first device 110 can perform location measurements that conflict with the CHO evaluation on candidate cell 430, and can start the CHO evaluation on cell 440 after the location measurement is completed or after the location measurement interval ends. In the following, the first device 110 can access candidate cell 140 on cell 450 by using post-handover resources.
[0199] To ensure that candidate cell 140 can also provide resources after the handover. Figure 4 As shown, based on the determination that the positioning measurement at the first device 110 conflicts with the CHO execution evaluation on the candidate cell 140, the serving cell 130 can transmit a fifth message 420 to the candidate cell 140, wherein the fifth message indicates that the candidate cell shift will be used for resources to perform CHO on the candidate cell.
[0200] In addition, whether or not resource exchange is allowed can be enabled as needed.
[0201] In some embodiments, if the serving cell 130 determines a conflict between positioning measurements (e.g., UE GNSS) and the CHO, the serving cell 130 may need to query the candidate cell 140 whether its resources can be shifted by transmitting a fifth message to the candidate cell 140, which requests the candidate cell 140 to shift its resources. Optionally, the candidate cell 140 may transmit a 425 response to the serving cell 130, indicating that the resources can be shifted. In some cases, the serving cell 130 may transmit a second indication to the first device 110, indicating that the first device is permitted to shift the CHO to begin the evaluation process.
[0202] Alternatively, in some embodiments, the serving cell 130 may transmit a second indication to the first device 110, indicating that the first device is permitted to initiate the evaluation by shifting the CHO. In some example embodiments, the second indication may be included in the CHO configuration.
[0203] Additionally, the fifth message can be transmitted to candidate cell 140 under the conditions of the second instruction.
[0204] To better understand, some example implementations are discussed, in which GNSS measurements are used as examples of positioning measurements.
[0205] In some example embodiments, in the case of enhanced machine-class communication (eMTC), when conditional handover is prepared and GNSS measurements begin, the serving node may notify the target node to extend the retention time to allow the UE to perform a delayed CHO execution assessment and complete the conditional handover. In some embodiments, the CHO may be performed based on location, time, and / or radio measurements, and in the case of long GNSS measurements, all types of assessments (and / or CHO execution) will be delayed.
[0206] In some example embodiments, the first device 110 may be implicitly aware of the retained displacement, or the CHO configuration may define whether such displacement is allowed or not in the event of a conflict with GNSS measurements.
[0207] According to some embodiments, C-DRX scenarios can be further improved. See now for reference. Figure 5 The diagram 500 illustrates a signaling diagram for communication according to some example embodiments of the present disclosure.
[0208] In some example embodiments, the second device 120 may transmit 510 a C-DRX configuration indicating at least one activity duration to the first device 110. Figure 5 In this process, the first device 110 can perform 520 positioning measurements.
[0209] In the following, for the first device 110, in response to at least one activity duration overlapping with the 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.
[0210] Therefore, in some example embodiments, for the second device 120, in response to the overlap of the activity duration of at least one activity duration with the positioning measurement gap, the second device 120 may transmit control information at the end of the positioning measurement gap, the control information indicating at least one pending transmission of the first device.
[0211] like Figure 5 As shown, the first device can wake up during T2 (e.g., exit C-DRX mode) and can monitor control information during T2. In some example embodiments, T2 can be a configured / default ON duration or a configured / default wake-up duration.
[0212] In some example embodiments, the second device 120 may transmit a configuration to the first device 120 that may indicate at least one of the following: a third indication that the first device is allowed to wake up at the end of the measurement gap, or the ON duration (e.g., T2) after the measurement gap.
[0213] To better understand, some example implementations are discussed, in which GNSS measurements are used as examples of positioning measurements.
[0214] 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 the GNSS measurement gap, in addition to the normal C-DRX configuration.
[0215] According to some embodiments, mobility measurement can be further improved. Reference now. Figure 6 The diagram 600 illustrates a signaling diagram for communication according to some example embodiments of the present disclosure.
[0216] In operation, the first device 110 receives from the second device 120 a measurement configuration 610 for configuring mobility measurements of neighboring cells (e.g., cell 140).
[0217] In the following description, the first device 110 can perform a location measurement that conflicts with mobility measurement in neighboring cells. The first device 110 can relax the requirements for mobility measurement in neighboring cells.
[0218] Furthermore, the relaxation process can be controlled / configured by the second device 120 / serving cell 130. Specifically, in some example embodiments, the first device 110 can receive a sixth message from the second device 120, which indicates at least one of the following:
[0219] The fourth instruction indicates that if mobility measurement conflicts with positioning measurement, the first device is permitted to relax the requirements for mobility measurement in adjacent cells; or
[0220] At least one parameter used to relax the requirements.
[0221] To better understand, some example implementations are discussed, in which GNSS measurements are used as examples of positioning measurements.
[0222] In some example embodiments, the second device 120 may instruct the first device 110 to relax RLM / RRM measurement requirements, such as the time required to assess a target cell, when the measurement conflicts with the GNSS measurement gap. In some example embodiments, this instruction may be provided in a GNSS or mobility measurement configuration.
[0223] Using the above process, the UE can better handle long GNSS position fixation durations, especially when GNSS measurement gaps conflict with RLM / RRM measurements.
