Description

Technical Field

[0001] Various embodiments of the present disclosure generally relate to the field of telecommunication, and more specifically, to a method, device, apparatus, and computer-readable storage medium for monitoring control information in a positioning gap.

Background Art

[0002] In a new radio (NR) non-terrestrial network (NTN), it is assumed that a user equipment (UE) always has the function of global navigation satellite system (GNSS) measurement and realizes its positioning according to the measured GNSS information. Hereinafter, more research on the support of the internet of things (IoT) via a non-terrestrial network (NTN) will be described. The 3rd generation partnership project (3GPP) assumes that a UE cannot operate GNSS and IoT NTN simultaneously. Therefore, the radio access network working group 1 (RAN1) and RAN working group 2 (RAN2) define a GNSS measurement gap in which a UE can perform GNSS measurement without monitoring a physical downlink control channel (PDCCH) and executing other "3GPP tasks".

Furthermore, communication between terminal devices and network devices in a communication network may be conducted in accordance with any appropriate generation of communication protocol, including but not limited to first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, fifth-generation (5G) communication protocols, and / or any other protocols currently known or to be developed in the future. Embodiments of this disclosure can be applied to a variety of communication systems. Given the rapid advancements in communications, there will naturally be future types of communication technologies that can be implemented alongside this disclosure. The scope of this disclosure should not be considered to be limited to the systems described above.

[0025] As used herein, the term “network device” refers to a node in a communications network through which terminal devices access and receive services from the network. Depending on the terminology and technology applied, network devices may include, for example, base stations (BS) or access points (AP), node B (NodeB or NB), advanced node B (eNodeB or eNB), NR NB (also called gNB), remote radio units (RRU), radio headers (RH), remote radio heads (RRH), relays, Integrated Access and Backhaul (IAB) nodes, low-power nodes such as femto and pico, non-terrestrial network (NTN) or non-terrestrial network devices such as satellite network devices, low earth orbit (LEO) satellites and geosynchronous earth orbit (GEO) satellites, aircraft network devices, and the like. In some exemplary embodiments, the radio access network (RAN) partitioning architecture includes centralized units (CUs) and distributed units (DUs) in an IAB donor node. The IAB node includes a mobile terminal (IAB-MT) section that behaves like a UE with respect to the parent node, and the DU section of the IAB node behaves like a base station with respect to the next-hop IAB node.

[0026] The term "terminal device" refers to any terminal equipment that may be capable of wireless communication. For example, terminal devices may also be called communication devices, user equipment (UE), subscriber station (SS), portable subscriber station, mobile station (MS), or access terminal (AT). Terminal devices may include, but are not limited to, mobile phones, cellular phones, smartphones, voice over IP (VoIP) phones, wireless local loop phones, tablets, wearable terminal devices, personal digital assistants (PDAs), portable computers, desktop computers, image capture terminal devices such as digital cameras, game terminal devices, music recording and playback devices, vehicle-mounted wireless terminal devices, wireless endpoints, mobile stations, laptop-embedded equipment (LEE), laptop-mounted equipment (LME), USB dongles, smart devices, wireless consumer-premises equipment (CPE), Internet of Things (IoT) devices, watches or other wearables, 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 in the context of industrial and / or automated processing chains), consumer electronic devices, and devices operating on commercial and / or industrial wireless networks. A terminal device may also correspond to the mobile termination (MT) portion of an IAB node (for example, a relay node). In the following description, the terms “terminal device,” “communication device,” “terminal,” “user equipment,” and “UE” may be used interchangeably.

[0027] As used herein, the terms “resource,” “transmit resource,” “resource block,” “physical resource block” (PRB), “uplink resource,” or “downlink resource” may refer to any resource for communication, such as communication between a terminal device and a network device, including resources in the time domain, resources in the frequency domain, resources in the spatial domain, resources in the code domain, or any other resources that enable communication. Hereinafter, unless otherwise specified, resources in both the frequency domain and the time domain are used as examples of transmit resources 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.

[0028] As mentioned above, in NR NTN, IoT NTN, or other types of NTN, it is assumed that the UE always has GNSS measurement capabilities and achieves location determination according to the measured GNSS information.

[0029] GNSS can be used by a UE to determine its position so that it can compensate for radio wave propagation between the UE and the satellite. This allows the UE to pre-compensate for uplink transmissions in the time and frequency domains, taking into account the long propagation distance to the satellite (up to 36,000 km for geostationary satellites). In the case of low Earth orbit satellites, the UE can also take into account the satellite's motion, as such satellites move relative to the Earth at 7.5 km / s.

[0030] In this disclosure, GNSS measurements can be triggered by a network device or UE.

[0031] Specifically, a network device can trigger a UE to perform GNSS measurements during a scheduled gap. Furthermore, in some exemplary embodiments, the network device can at least support triggering a 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 GNSS validity period. If the UE is in connected mode, the UE can report the GNSS validity period via the MAC CE. Furthermore, in some exemplary embodiments, the UE may also report the "GNSS positioning duration" (i.e., the time required for the UE to perform GNSS measurements) at least during the initial access phase. The parameter "GNSS positioning duration" can be used by the network device to determine the length of the GNSS measurement gap. In some exemplary embodiments, a new downlink MAC CE may be introduced to trigger a connected UE to perform GNSS measurements.

[0032] In GNSS measurements under a Radio Resource Control (RRC) connection, if a network device non-periodically triggers the connected UE to perform a GNSS measurement, the UE can reacquire its GNSS position through the gap.

[0033] If the GNSS measurement gap is triggered aperiodically by MAC CE, the duration of the GNSS measurement gap can be configured by eNB. Furthermore, if the duration of the GNSS measurement gap is not included in the configuration by eNB, the gap duration is equal to the most recently reported GNSS positioning duration for the measurement.

[0034] If the UE does not receive a trigger for a GNSS measurement from the network device, the UE may perform the GNSS measurement autonomously. In this scenario, the network device and the UE must have a common understanding of when and how to start the GNSS measurement. As a specific embodiment, since the UE is not available for scheduling during the GNSS measurement period, the UE may perform the GNSS measurement autonomously at the expiration of the GNSS validity period.

[0035] A specific example is when a network device aperiodically triggers a connected UE to perform a GNSS measurement in the context of RRC connectivity. Furthermore, if configured to allow autonomous triggering of GNSS measurements, the UE may autonomously reacquire GNSS data if it does not receive a trigger from the network device to perform a GNSS measurement.

[0036] From a RAN1 perspective, uplink transmission may be possible during a period X after the expiration of the original GNSS validity period without GNSS reacquisition, provided that the frequency error and timing error are within the frequency and timing error requirements of conventional closed-loop time correction.

[0037] The UE may not be required to transmit or receive any channels / signals during the aperiodic GNSS measurement gap duration before the UE successfully reacquires GNSS data.

[0038] Furthermore, the UE can report a single GNSS positioning duration for GNSS measurement via a 4-bit field having component values ​​[1,2,3,4,5,6,7,13,19,25,31,6*n+1,...].

[0039] In some exemplary embodiments, the GNSS validity period reported by the UE may be the remaining validity period. In some exemplary embodiments, the UE may trigger a GNSS measurement report each time a GNSS positioning operation is completed.

[0040] As can be seen from the above, the eNB can aperiodically trigger a GNSS measurement gap (MG) in which the UE can perform measurements, and this trigger can be based on the downlink MAC CE, allowing the network to freely decide when to trigger the GNSS measurement.

[0041] As mentioned above, 3GPP assumes that a UE cannot operate GNSS and IoT NTN simultaneously, and therefore RAN1 and RAN2 define a GNSS measurement gap during which a UE can perform GNSS measurements without monitoring the physical downlink control channel (PDCCH) and other "3GPP tasks".

[0042] Generally speaking, since the 3GPP receiver is unavailable while the GNSS receiver is active, a UE should not monitor the PDCCH while it is performing a GNSS measurement. Also, the 3GPP receiver may be available when the UE has completed its GNSS measurement. However, the network may not know that the UE has finished its GNSS measurement, and therefore, the network should not schedule the UE using the PDCCH until it has confirmed that the UE is able to monitor the PDCCH.

[0043] With this in mind, if the UE can provide early feedback on completed GNSS measurements, such as an SR or other indication regarding the reporting of the remaining GNSS validity period, the network can understand that the GNSS measurements are complete. In that case, the network can then begin PDCCH scheduling earlier.

[0044] If the UE has completed the GNSS measurement before the end of the GNSS measurement gap, and the UE can report a new remaining GNSS validity period after a successful GNSS measurement, another issue is how to ensure that the network and the UE have a common understanding regarding whether and how to perform PDCCH transmission (for the network) and whether and how to perform PDCCH monitoring / reception (for the UE).

[0045] According to some exemplary embodiments of the present disclosure, a solution is provided for monitoring control information in a position measurement gap. In this solution, upon determination that position measurement is complete in a position measurement gap, a first device (such as a terminal device) determines a first time point for transmitting first information indicating the completion of position measurement, and then determines whether to begin monitoring control information from a second device (such as a network device) before the end of the position measurement gap, based on at least one of the first time point, round-trip time (RTT) between the first and second devices, processing time required for the second device to process the first information, or an offset associated with monitoring control information. The second device may also determine whether to begin transmitting control information accordingly. As a result, transmission of control information can be performed within the position measurement gap, and therefore control information can be transmitted to the first device in a timely manner.

[0046] The terms “gap,” “duration,” “period,” “cycle,” “length of time,” and “window” as used herein may be used interchangeably.

[0047] In the following, a satellite is used as an example of a network device to illustrate some specific exemplary embodiments of the disclosure. It should be noted that the exemplary embodiments described with respect to a satellite are equally applicable to other types of network devices; the disclosure is not limited thereto.

[0048] Furthermore, GNSS measurements may be used as examples of positioning to illustrate some specific exemplary embodiments of certain aspects of this disclosure. It should be noted that the exemplary embodiments described with respect to satellites are equally applicable to other types of positioning, such as 3GPP-based positioning (e.g., multi-RTT or observation arrival time difference OTDOA). This disclosure is not limited thereto.

[0049] In some exemplary embodiments, "UE-eNB RTT" may be used as an example of RTT between a first device and a second device. Specifically, in the case of a non-terrestrial network, UE-eNB RTT may refer to the sum of the UE's timing advance value and k-Mac, which is measured in units of subframes that are not rounded or truncated to an integer number of subframes. It should be understood that if this solution is applied to scenarios other than NTN, the definition of RTT may be redefined accordingly.

[0050] Please note that the PDCCH for NB-IoT will be referred to as NPDCCH. This disclosure is equally applicable to this control channel as well.

[0051] The principles and embodiments of this disclosure will be described in detail below with reference to the drawings.

[0052] It should be noted that none of the section / subsection headings shown herein are intended to be limiting. Embodiments are described throughout this specification, and any type of embodiment may be included in any section / subsection. Furthermore, any embodiment disclosed in any section / subsection may be combined in any way with any other embodiment described in the same section / subsection and / or different sections / subsections.

[0053] Exemplary Embodiments Figure 1 shows an exemplary communication environment 100 in which an exemplary embodiment of the present disclosure can be implemented. 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.

[0054] In the embodiment shown in Figure 1, the first device 110 may include a terminal device, and the second device 120 may include a network device that provides services to the terminal device. The serving area of ​​the second device 120 may be referred to as a cell 130. It should be understood that the second device 120 can be deployed either inside or outside of cell 130, depending on different requirements scenarios.

[0055] In some exemplary embodiments, the communication environment 100 is an NTN network including one or more satellites. In some exemplary embodiments, access network devices (such as gNBs) may be deployed on the satellites, also known as a regenerative relay architecture. Alternatively, in some exemplary embodiments, the access network devices may be deployed separately from the satellites, such as by being deployed on the ground, also known as a transparent relay architecture. In this disclosure, depending on a particular application scenario or requirement, either or both of the satellites and the access network devices may be considered as a second device 120. This disclosure is not limited thereto.

[0056] In the following, for illustrative purposes, some exemplary embodiments will be described using a first device 110 operating as a terminal device and a second device operating as a network device. However, in some exemplary embodiments, the operations described in relation to a terminal device may be performed in a network device or other device, and the operations described in relation to a network device may be performed in a terminal device or other device.

[0057] In some exemplary embodiments, when 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 called a downlink (DL), while the link from the first device 110 to the second device 120 is called an uplink (UL). In a DL, the second device 120 is a transmit (TX) device (or transmitter) and the first device 110 is a receive (RX) device (or receiver). In a UL, the first device 110 is a TX device (or transmitter) and the second device 120 is an RX device (or receiver).

[0058] Communication in communication environment 100 can be carried out in accordance with 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 Institute for Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocols currently known or to be developed in the future. Furthermore, communication may use 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 (OFDM), Discrete Fourier Transform spread OFDM (OFT-s-OFDM), and / or any other technology currently known or to be developed in the future.

[0059] Communication operating principles and signaling examples The following section will describe the details of the operation upon completion of position measurement (GNSS, etc.), referring to Figures 2 to 5. For the purpose of explanation, the signaling flow illustrated in Figures 2 to 5 will be described using, for example, the first device 110 and the second device 120, referring to Figure 1.

[0060] In the embodiments shown in Figures 2 to 5, the first device 110 functions as a terminal device, and the second device 120 functions as a network device.

[0061] It should be understood that the operations of the first device 110 and the second device 120 must be coordinated. In other words, the second device 120 and the first device 110 must have a common understanding of rules, configurations, parameters, etc. Such a common understanding can be achieved through any appropriate interaction or by applying the same rules / policies.

[0062] In the following, some operations will be described from the perspective of the first device 110, but please understand that the corresponding operations must be performed by the second device 120. Similarly, some operations will be described from the perspective of the second device 120, but please understand that the corresponding operations must be performed by the first device 110. For the sake of brevity, some identical or similar content will be omitted in this specification.

[0063] Furthermore, in the following description, examples of message types (such as “RRC message”, “MAC CE”, and “DCI”) are for illustrative purposes only and do not imply any limitation. In other exemplary embodiments, any suitable message type may be used for interaction between the first device 110 and the second device 120.

[0064] In summary, the following exemplary embodiment clearly defines when the UE should monitor the PDCCH, depending on the relationship between the UE-eNB RTT and the end of the GNSS measurement gap configured by the network, and the timing of when the UE should transmit the first information (which concerns the new remaining GNSS validity period, and is therefore sometimes referred to as "information concerning the new remaining GNSS validity period") and the end of the GNSS measurement gap configured by the network.

[0065] During operation, the first device 110 performs position measurement 230. Next, in accordance with the determination that the position measurement has been completed in the position measurement gap, the first device 110 determines a first time point 240 for transmitting first information indicating the completion of the position measurement.

[0066] Next, the first device 110 determines, based on one or more factors, whether or not to start monitoring control information from the second device 120 before the end of the position measurement gap.

[0067] In some exemplary embodiments, the position measurement may be a 3GPP-based position measurement (such as multi-RTT or OTDOA) or a Global Navigation Satellite System (GNSS) measurement.

[0068] In some exemplary embodiments, control information can be transported via a physical downlink control channel (PDCCH).

[0069] Examples of one or more factors are as follows: - At the first point in time, - Round-trip time (RTT) between the first device 110 and the second device 120, - The processing time required for the second device 120 to process the first information, or - An offset associated with monitoring control information.

[0070] In some exemplary embodiments, the offset refers to a time offset used to delay the monitoring of control information. The reference point can be defined as any suitable time, such as a first time point or other time points. Furthermore, in some exemplary embodiments, the offset associated with the monitoring of control information can be defined as a default value configured by the second device 120 or reported by the first device 110.

[0071] In some exemplary embodiments, the first device 110 can transmit first information to the second device 120. In this way, the second device can obtain a more accurate time point in time regarding when the first device 110 has completed position measurement.

[0072] The first piece of information will be described in more detail below. In some illustrative embodiments, the first piece of information may be one of the following: - Scheduling Request (SR), - Buffer Status Report (BSR), - Physical Random Access Channel (PRACH) transmission, or - Media Access Control (MAC) control element (CE).

[0073] In some exemplary embodiments, the first information can be transmitted using a pre-configured resource.

[0074] In some exemplary embodiments, it may be necessary to first determine a first monitoring opportunity for control information before transmitting the first information. In some embodiments, the first monitoring opportunity may occur after a first time point in time when the first message is transmitted using a pre-configured resource.

[0075] Alternatively, in some exemplary embodiments, the first monitoring opportunity may occur after a second time point in time that is a certain period after the first time point. Furthermore, this period may be determined based on at least one of RTT, processing time, or an offset associated with monitoring the control information. In one exemplary embodiment, the period may be RTT. In another exemplary embodiment, the period may be the sum of RTT and processing time. In a further exemplary embodiment, the period may be an offset associated with monitoring the control information.

[0076] The following describes how to determine whether or not to start monitoring control information from the second device 120 before the end of the position measurement gap, based on one or more of the above factors.

[0077] In some exemplary embodiments, the first device 110 may begin monitoring control information before the end of the position measurement gap, according to the determination that the end of the position measurement gap is after a second time point which is a certain period after the first time point 260-1. As described above, the period can be determined based on at least one of RTT, processing time, or an offset associated with monitoring control information.

[0078] Therefore, the second device 120 can start transmitting control information before the end of the position measurement gap, according to the determination that the end of the position measurement gap is after a second point in time which is a certain period after the reception of the first information 260-2.

[0079] In some exemplary embodiments, the first device 110 may begin monitoring control information after the end of a position measurement gap, based on the determination that the end of the position measurement gap is before a second time point which is a certain period after a first time point.265-1 As described above, the period can be determined based on at least one of RTT, processing time, or an offset associated with monitoring control information.

[0080] Therefore, the second device 120 can start transmitting control information after the end of the position measurement gap, according to the determination that the end of the position measurement gap is before a second time point which is a certain period after the first time point 265-2.

[0081] If the first device is configured in a discontinuous receiver (DRX) configuration, it is possible to further determine, based on the DRX configuration, when to monitor control information.

[0082] In some exemplary embodiments, if the first device 110 is configured with a DRX configuration, the first device 110 may apply the DRX configuration after the second time point. Applying the DRX configuration means monitoring the first DRX-on period after the second time point.

[0083] Alternatively, in some exemplary embodiments, if the first device 110 is configured in a DRX configuration, the first device 110 can enter a DRX active time after a second time point without waiting for a first on period configured by the DRX configuration.

[0084] In some exemplary embodiments, the first device 110 can receive second information from the second device 120, the second information indicating at least one of the following: - A first indication used to enable or disable the transmission of first information before the end of the positioning gap, - A second indication used to enable or disable monitoring of control information prior to the position measurement gap, or - A third indication used to enable or disable monitoring of control information after the end of the position measurement gap and before a second time point which is a certain period after the first time point.

[0085] Furthermore, all of the above procedures may be performed as UE functions or configured by the second device 120.

[0086] As shown in Figure 2, in some exemplary embodiments, the first device 110 can transmit third information to the second device 120, the third information indicating at least one of the following: - Function-related information that indicates whether the first device 110 supports the transmission of first information before the end of the position measurement gap, - Second function-related information that indicates whether the first device 110 supports monitoring of control information before the end of the position measurement gap, or - Third function-related information that indicates whether the first device 110 supports monitoring of control information after the end of the position measurement gap and a second time point which is a certain period after the first time point.

[0087] For the sole purpose of making the above procedure easier to understand, some exemplary embodiments will be explained with reference to Figures 3A to 4B, which show the timings 300A, 300B, 400A, and 400B for monitoring control information in the position measurement gap.

[0088] In some exemplary embodiments, if the reporting time for "New remaining GNSS validity period information" and "UE-eNB RTT" is before the end of the scheduled GNSS measurement gap, the UE can initiate PDCCH monitoring before the end of the measurement gap, i.e., during duration 310, the UE can initiate PDCCH monitoring as shown in Figure 3A.

[0089] In some exemplary embodiments, “New remaining GNSS validity period information” may be an SR, BSR, PRACH, or MAC CE transmission of the new remaining GNSS validity period on a pre-configured resource.

[0090] In some exemplary embodiments, the UE reports "new remaining GNSS lifetime information" in a pre-configured resource or PRACH resource for SR / BSR. The UE can determine a first PDCCH monitoring opportunity based on when it sends the report or PRACH (to synchronize with the network before the report reaches the network), and the time of the pre-configured resource is known to the network. The network can assume that the UE can report new remaining GNSS lifetime in a predefined resource, i.e., this report will not affect PDCCH monitoring and, for example, scheduled DL data.

[0091] In some exemplary embodiments, if the reporting times for "New Remaining GNSS Validity Period Information" and "UE-eNB RTT" fall after a scheduled GNSS measurement gap, the UE can begin PDCCH monitoring at the end of the measurement gap (i.e., before the eNB has received the information). As shown in Figure 3B, the UE can monitor PDCCH during duration 350.

[0092] In a further embodiment, the network defines / configures the following: - Whether or not the UE can provide information early, i.e., before the end of the GNSS measurement gap, i.e., before the reporting time + RTT has elapsed, i.e., the first indication, - Regardless of whether the UE has been reported early or not, is it expected that the UE will monitor PDCCH before the end of the GNSS measurement gap, i.e., a second indication? - In a scenario where the UE reports (relatively) late, is it expected that the UE will monitor the PDCCH between the end of the GNSS measurement gap and the next reporting time + RTT, i.e., a third indication?

[0093] In some exemplary embodiments, PDCCH monitoring opportunities may be based on C-DRX, if configured. In this case, the UE would monitor the PDCCH based on whether it is within a DRX active time (e.g., within a first C-DRX on period 410, as shown in Figure 4A) that occurs after the UE has determined that PDCCH monitoring needs to be resumed before the end of the configured measurement gap. In Figure 4A, the UE monitors on period #A (while within the GNSS measurement gap) instead of postponing monitoring until after the GNSS measurement gap (on period #B).

[0094] In another embodiment, the UE can be triggered to enter a C-DRX active time (such as active time 450 as shown in Figure 4B) after the reporting time and "UE-eNB RTT" by triggering the start of an on-period timer or a drx-inactive timer, but this will only be done based on the eNB configuration. In one exemplary embodiment of Figure 4B, the UE starts a new active time #X immediately after the reporting time and "UE-eNB RTT" rather than waiting for on-period A. Alternatively, in another exemplary embodiment of Figure 4B, the UE starts a new active time #X immediately after the reporting time and continues to monitor on-period #A after that new active time #X.

[0095] In some embodiments, the network may assume that the UE has completed its measurements early and is therefore able to monitor the PDCCH early. This can reduce latency, but it also wastes resources and energy if the UE does not complete its measurements early. The UE may choose to monitor the PDCCH in a known window, for example, immediately after pre-configured resources. If the UE receives nothing in this window, it can determine that the network is not employing opportunistic techniques. The UE would then fall back to monitoring the PDCCH according to the other option, namely after the reporting time and the "UE-eNB RTT".

[0096] Next, we refer to Figure 5, which shows a flowchart of Method 500, performed in a first apparatus according to an exemplary embodiment of part of the present disclosure.

[0097] In Figure 5, the UE can report the GNSS positioning duration and the remaining GNSS validity period, and can receive a GNSS measurement gap configuration that includes a PDCCH monitoring rule used to determine whether to start monitoring control information before the end of the position measurement gap. The UE can then receive a GNSS measurement trigger and perform a GNSS measurement.

[0098] If necessary, the UE may transmit new information about the remaining GNSS validity period at time T. The UE can determine whether the transmission time T and the UE-eNB RTT (which may include the processing time required for the NW to process the new information about the remaining GNSS validity period, the offset associated with monitoring the control information, and any other relevant factors) are before the end of the GNSS measurement gap. If so, the UE can monitor the PDCCH after the transmission time T and UE-eNB RTT; otherwise, the UE can monitor the PDCCH after the end of the GNSS measurement gap.

[0099] In summary, after the UE successfully reacquires GNSS, the UE can be considered uplink synchronized. As a result, the UE can initiate uplink transmission to report the new remaining GNSS validity period. However, the network will not recognize that the UE has terminated its measurement early / before the end of the GNSS measurement gap until the UE has initiated such uplink transmission for reporting. Therefore, the UE does not need to monitor PDCCH until the first uplink transmission and UE-eNB RTT if it occurs before the end of the GNSS measurement gap. The UE does need to monitor PDCCH after the first uplink transmission and UE-eNB RTT if it occurs before the GNSS measurement gap, according to the process illustrated above.
