[0031] This disclosure presents a method and apparatus for measuring global navigation satellite systems.

[0032] In a first aspect, embodiments of this disclosure propose a global navigation satellite system measurement method, executed by a terminal, the method comprising:

[0033] In time-division duplex mode, it receives global navigation satellite system signals within the measurement gaps of the global navigation satellite system;

[0034] The signals of the Global Navigation Satellite System are measured.

[0035] The present invention discloses a global navigation satellite system measurement method. When the UE is in TDD mode, it first receives GNSS signals within the GNSS measurement gap, and then measures the received GNSS signals. This avoids the UE frequently entering the idle state after the GNSS-related information expires, ensuring that the UE can perform GNSS measurements efficiently and reducing power consumption.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0037] Receive first information; the first information is used to instruct the global navigation satellite system to measure the gap.

[0038] In the above embodiments, the GNSS measurement gap is configured by the network device. Specifically, the network device sends first information, which the UE receives. This first information indicates the GNSS measurement gap. The UE determines the GNSS measurement gap for receiving GNSS signals based on this first information. The first indication information may include the start point of the GNSS measurement gap, the time period of the GNSS measurement gap, and the period of the GNSS measurement gap. The indication of the start point of the GNSS measurement gap may be an offset relative to the reception time slot of the GNSS measurement gap indicating the MAC CE, or an offset of the time slot in which the UE feeds back ACK-NACK information for that MAC CE. This method is flexible and expands its applicability.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, the GNSS measurement gap is preset. The preset protocol includes the start point of the GNSS measurement gap, the time period of the GNSS measurement gap, the period of the GNSS measurement gap, etc. The indication of the start point of the GNSS measurement gap may be relative to a certain radio frame, subframe, or one of the following specific downlink channels:

[0040] Narrowband physical downlink shared channel information;

[0041] Narrowband physical downlink control channel information;

[0042] Narrowband system information block type 1;

[0043] Narrowband master synchronization signal;

[0044] Narrowband auxiliary synchronization signal.

[0045] In the above embodiments, the GNSS measurement gap is preset, that is, the GNSS measurement gap is predefined by the protocol. This method does not require network devices to configure GNSS measurement gaps, reduces signaling overhead, and improves efficiency.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, the Global Navigation Satellite System measurement gaps are located within narrowband IoT subframes that are not used by the terminal. These unused narrowband IoT subframes are not used to perform uplink or downlink NB-IoT services. These unused narrowband IoT subframes include non-uplink narrowband IoT subframes (non-U NB-IoT subframes) and non-downlink narrowband IoT subframes (non-D NB-IoT subframes).

[0047] In the above embodiments, GNSS signals are received in Iridium system subframes not used by the UE, avoiding conflicts between receiving GNSS signals and transmitting NB-IoT NTN related information, and ensuring the transmission efficiency of information related to the NB-IoT NTN TDD mode system.

[0055] In the above embodiments, the target information that originally needed to be received on the downlink subframe of the narrowband IoT was discarded or delayed. The GNSS signal measurement period of the UE should include these discarded or delayed subframes, which expands the range of resources that can be used for GNSS measurement, further ensuring that the UE can perform GNSS measurement efficiently and further reducing power consumption.

[0062] In the above embodiments, at least one of the NPDSCH information, NPDCCH information, SIB1-NB, NPSS, and NSSS that originally needed to be received on the target downlink subframe is discarded or delayed. The UE's GNSS signal measurement period should include these discarded or delayed subframes, which expands the range of resources that can be used for GNSS measurement, further ensures that the UE can perform GNSS measurement efficiently, and further reduces power consumption.

[0166] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things (IoT) device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, narrowband Internet of Things (NB-IoT) terminal, and bandwidth-reduced low-complexity or coverage-enhanced (BL / CE) terminal, but is not limited thereto.

[0167] In some embodiments, network device 102 may include at least one of access network device, core network device, and satellite device.

[0168] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network.

[0169] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0170] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0171] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0172] In some embodiments, the satellite equipment includes at least one of GNSS satellites and NTN satellites. NTN satellites include at least one of transparently relaying satellites and satellites carrying base stations.

[0173] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0174] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0175] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0176] In some embodiments, for a Narrow Band Internet of Things (NB-IoT) UE in an NTN Frequency Division Duplex (FDD) serving cell, when the UE receives a GNSS measurement command from a Media Access Control (MAC) Element (MAC CE) in an NPDSCH, where the NPDSCH ends in downlink subframe n, the GNSS measurement gap is determined based on the following conditions:

[0177] 1. If the UE does not provide a Hybrid Automatic Repeat reQuest (HARQ) acknowledgement (HARQ-ACK) message for the Hybrid Automatic Repeat reQuest (HARQ) process, which is associated with the NPDSCH transport block carrying the GNSS measurement command MAC CE, the UE should assume that the GNSS measurement gap begins in downlink subframe n+13.

[0178] 2. If the UE provides HARQ-ACK information for the HARQ process, the HARQ process is associated with the NPDSCH transport block carrying the GNSS measurement command MAC CE. The UE should assume that the GNSS measurement gap starts in downlink subframe k+2, where k is the first downlink subframe after the Narrow band Physical Uplink Shared Channel (NPUSCH) transmission ends. The NPUSCH is used to carry the acknowledgement (ACK) / negative acknowledgement (NACK) response for the HARQ process.

[0179] In some embodiments, the terms "uplink", "uplink", and "physical uplink" can be used interchangeably, as can the terms "downlink", "downlink", and "physical downlink", as well as the terms "sidelink", "sidelink", "sidelink communication", "sidelink communication", "direct connection", "direct link", "direct communication", and "direct link communication".

[0180] In some embodiments, for NB-IoT UEs in an NTN FDD serving cell during GNSS measurement gaps, the UE does not need to monitor the NPDCCH until it reacquires its GNSS location and performs contention-based random access.

[0181] In some embodiments, for a Bandwidth-reduced Low-complexity or Coverage Enhanced (BL / CE) UE in an NTN FDD serving cell, when the UE receives a GNSS measurement command MAC CE in the PDSCH, where the PDSCH ends in downlink subframe n, the GNSS measurement gap is determined according to the following conditions:

[0182] 1. If the UE does not provide HARQ-ACK information for the HARQ process, the HARQ process is associated with the Physical Downlink Shared Channel (PDSCH) transport block carrying the GNSS measurement command MAC CE, and the UE should assume that the GNSS measurement gap begins in downlink subframe n+6.

[0183] 2. If the UE provides HARQ-ACK information for the HARQ process, the HARQ process is associated with the PDSCH transport block carrying the GNSS measurement command MAC CE. The UE should assume that the GNSS measurement gap starts in downlink subframe k+2, where k is the first downlink subframe after the PDSCH transmission ends. The HARQ process is associated with the Physical Downlink Shared Channel (PDSCH) transport block.

[0184] In some embodiments, for a BL / CE UE in an NTN FDD serving cell, during the GNSS measurement gap, the UE does not need to monitor the Machine Type Communication Physical Downlink Control Channel (MPDCCH) until it reacquires its GNSS location and performs contention-based random access.

[0185] The timing relationship between BL / CE UEs and typical NB-IoT UEs in MAC CEs with HARQ-ACK feedback differs slightly. However, logically, terminals within GNSS measurement gaps should not perform control channel listening but should focus on GNSS signal acquisition and tracking to ensure positioning accuracy. Once positioning is complete, the terminal will continue subsequent data transmission, as illustrated in Figure 1B.

[0186] The relevant technical solutions do not yet support GNSS measurement in TDD mode. As a result, NTN terminals working in IoT TDD mode have to frequently enter idle mode in order to obtain GNSS measurement results, resulting in high power consumption.

[0187] In some embodiments, terms such as "physical downlink shared channel (PDSCH)" and "DL data" can be used interchangeably, as can terms such as "physical uplink shared channel (PUSCH)" and "UL data".

[0188] Figure 2A is one of the exemplary interactive schematic diagrams of a global navigation satellite system measurement method provided according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to a global navigation satellite system measurement method, which includes:

[0189] Step 2101: Network device 102 sends first information to terminal 101. The first information is used to instruct the Global Navigation Satellite System to measure the gap.

[0190] In some embodiments, the first information is used to indicate the global navigation satellite system measurement gap in TDD mode.

[0191] In some embodiments, terminal 101 receives first information sent by network device 102.

[0192] In some embodiments, the global navigation satellite system measurement gap is preset. Terminal 101 acquires the first information specified by the protocol, at which point step 2101 can be omitted.

[0193] In some embodiments, the terminal 101 obtains the first information from the upper layer(s), in which case step 2101 can be omitted.

[0194] In some embodiments, the terminal 101 processes the information to obtain the first information, and step 2101 can be omitted.

[0195] In some embodiments, the terminal 101 autonomously implements the function indicated by the first information, or the above function is a default or default value, in which case step 2101 can be omitted.

[0196] In some embodiments, the global navigation satellite system measurement gap includes one or more time windows, each time window including a start position and a window length, wherein the units of the start position and window length can be at least one of frames, subframes, time slots, and orthogonal frequency division multiplexing (OFDM) symbols.

[0197] In some embodiments, the Global Navigation Satellite System measurement gap indicated by the first information is located within a narrowband IoT subframe that is not used by the terminal 101. These unused narrowband IoT subframes are not used to perform uplink or downlink NB-IoT services. These unused narrowband IoT subframes include non-uplink narrowband IoT subframes (non-U NB-IoT subframes) and non-downlink narrowband IoT subframes (non-D NB-IoT subframes). Figure 2B is a schematic diagram of subframes in TDD mode according to an embodiment of this disclosure. As shown in Figure 2B, the unused narrowband IoT subframes are the subframes other than those within the dashed and solid boxes. The subframes are located outside the downlink active subframes of the Iridium system.

[0198] In some embodiments, the Global Navigation Satellite System (GNSS) measurement gap indicated by the first information includes narrowband Internet of Things (NB-IoT) downlink subframes. The start point and time period of the GNSS measurement gap are in the narrowband NB-IoT downlink subframes (i.e., NB-IoT subframes). Figure 2B is a schematic diagram of a subframe in TDD mode provided according to an embodiment of the present disclosure. As shown in Figure 2B, the narrowband NB-IoT downlink subframe is the subframe within the solid line box.

[0199] In some embodiments, if the information related to the Global Navigation Satellite System of terminal 101 fails, network device 102 sends first information to terminal 101.

[0200] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0201] In some embodiments, the terms "codebook," "codeword," and "precoding matrix" can be used interchangeably. For example, a codebook can be a collection of one or more codewords / precoding matrices.

[0202] In some embodiments, terms such as “moment,” “point in time,” “time,” and “time location” can be used interchangeably, as can terms such as “duration,” “segment,” “time window,” “window,” and “time.”

[0203] In some embodiments, the terms “frame”, “radio frame”, “subframe”, “slot”, “sub-slot”, “mini-slot”, “symbol”, “symbol”, and “transmission time interval (TTI)” can be used interchangeably.

[0204] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.

[0205] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0206] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0207] In some embodiments, the terms "precoding", "precoder", "weight", "precoding weight", "quasi-co-location (QCL)", "transmission configuration indication (TCI) status", "spatial relation", "spatial domain filter", "transmission power", "phase rotation", "antenna port", "antenna port group", "layer", "the number of layers", "rank", "resource", "resource set", "resource group", "beam", "beam width", "beam angular degree", "antenna", "antenna element", and "panel" can be used interchangeably.

[0208] In step 2102, network device 102 sends second information to terminal 101. The second information is used to indicate the target downlink subframe in the narrowband IoT downlink subframe.

[0209] In some embodiments, where the Global Navigation Satellite System measurement gap indicated by the first information includes a narrowband IoT downlink subframe, network device 102 can send second information to terminal 101. The network device uses the second information to inform the UE that a downlink narrowband IoT subframe is available. This method is more flexible and expands its applicability. The second information includes a bitmap, downlinkBitmapNonAnchor, or downlinkBitmap-r13.

[0210] In some embodiments, network device 102 can send second information to terminal 101 via a bitmap.

[0211] In step 2103, network device 102 drops or postpones the target information that was originally to be transmitted on the target downlink subframe.

[0212] In some embodiments, where the Global Navigation Satellite System measurement gap indicated by the first information includes a narrowband IoT downlink subframe, network device 102 discards or postpones target information that would otherwise need to be transmitted on a target downlink subframe within the narrowband IoT downlink subframe.

[0213] In some embodiments, "discarding" can be understood as "removing" or "discarding." Network device 102 discards the target information that was originally intended to be transmitted on the target downlink subframe within the narrowband IoT downlink subframe. This can be understood as network device 102 no longer transmitting the target information on the target downlink subframe. Terminal 101 does not expect to receive the target information on the target downlink subframe.

[0214] In some embodiments, the global navigation satellite system measurement gap includes a first time period, which is the time period during which target information is originally to be transmitted; the target information is not transmitted or is delayed during the first time period.

[0215] In some embodiments, the global navigation satellite system measurement gap includes the number of subframes for which receiving target information that would normally be received on the narrowband IoT downlink subframe is not expected, or the number of subframes for which receiving target information that would normally be received on the narrowband IoT downlink subframe is postponed.

[0216] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data and / or instructions received; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the receiver to respond to the sent content.

[0217] In some embodiments, network device 102 postpones the transmission of target information that would normally be sent on a target downlink subframe within the narrowband IoT downlink subframe. This can be understood as network device 102 not transmitting the target information on the target downlink subframe within the current period, but transmitting it on target downlink subframes in subsequent periods. Terminal 101 does not receive the target information on the target downlink subframe within the current period, but receives it on target downlink subframes in subsequent periods. The unit of the aforementioned period includes at least one of frames and subframes. In one embodiment, the period is 90 milliseconds (ms), i.e., 9 NB radio frames.

[0218] In some embodiments, the target information includes at least one of the following:

[0219] Narrowband physical downlink shared channel information;

[0220] Narrowband physical downlink control channel information;

[0221] Narrowband system information block type 1;

[0222] Narrowband master synchronization signal;

[0223] Narrowband auxiliary synchronization signal.

[0224] In some embodiments, the terms "synchronization signal (SS)," "synchronization signal block (SSB)," "reference signal (RS)," "pilot," and "pilot signal" can be used interchangeably.

[0225] Step 2104: When terminal 101 is in time-division duplex mode, network device 102 sends GNSS signals to terminal 101 within the GNSS measurement gap.

[0226] In some embodiments, when the terminal 101 is in time-division duplex mode, the terminal 101 receives the global navigation satellite system signal sent by the network device 102 within the global navigation satellite system measurement gap.

[0227] Step 2105: The terminal 101 measures the signal of the Global Navigation Satellite System to obtain information related to the Global Navigation Satellite System, such as its own position information.

[0228] In some embodiments, information related to the Global Navigation Satellite System includes at least one of the location information and time synchronization information of the terminal 101.

[0229] The global navigation satellite system measurement method disclosed in this embodiment may include at least one of steps 2101 to 2105. For example, step 2104 + step 2105 may be implemented as an independent embodiment, step 2101 + step 2104 + step 2105 may be implemented as an independent embodiment, step 2103 + step 2104 + step 2105 may be implemented as an independent embodiment, step 2101 + step 2103 + step 2104 + step 2105 may be implemented as an independent embodiment, and step 2101 + step 2102 + step 2103 + step 2104 + step 2105 may be implemented as an independent embodiment, but is not limited thereto.

[0230] In some embodiments, steps 2102 and 2103 may be performed in an alternate order or simultaneously, and steps 2103 and 2104 may be performed in an alternate order or simultaneously.

[0231] In some embodiments, steps 2101 and 2102 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0232] In some embodiments, step 2102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0233] In some embodiments, steps 2101, 2102, and 2103 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0234] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0235] Figure 2C is a second exemplary interactive schematic diagram of a global navigation satellite system measurement method provided according to an embodiment of the present disclosure. As shown in Figure 2C, the present disclosure relates to a global navigation satellite system measurement method, which includes:

[0236] Step 2201: Network device 102 sends first information to terminal 101. The first information is used to indicate the GNSS measurement gap. The first information may indicate the start point of the GNSS measurement gap, the time period of the GNSS measurement gap, the period of the GNSS measurement gap, etc. The indication of the start point of the GNSS measurement gap may be an offset relative to the reception time slot of the GNSS measurement gap indicating the MAC CE, or an offset of the time slot in which the UE feeds back ACK-NACK information for that MAC CE.

[0237] In some embodiments, the Global Navigation Satellite System measurement gap is located in a narrowband IoT subframe that the terminal 101 does not use to perform uplink or downlink narrowband IoT services.

[0238] The Iridium system time slots / subframes used by Terminal 101 include NB-IoT DL and UL time slots / subframes, meaning that the Global Navigation Satellite System measurement gaps do not include NB-IoT DL and UL time slots / subframes.

[0239] In some embodiments, it is determined which downlink subframes cannot be considered NB-IoT DL and UL subframes in the following manner:

[0240] 1. UE's rules for determining downlink subframes

[0241] The NB-IoT UE needs to determine whether a downlink subframe or a TDD-specific subframe configured for NB-IoT downlink transmission is an NB-IoT downlink subframe based on the following conditions:

[0242] 1.1 Judgment by exclusion criteria:

[0243] In some embodiments, if a subframe contains transmissions of NPSS / NSSS / NPBCH / SIB1-NB, then the subframe is not considered a downlink subframe.

[0244] In some embodiments, if the UE is operating in IoT-NTN TDD mode and the subframe is outside the downlink active subframe of the Iridium system, then the subframe is not considered an NB-IoT downlink subframe.

[0245] Figure 2B is a schematic diagram of a subframe in TDD mode according to an embodiment of the present disclosure. As shown in Figure 2B, the dashed box represents the IoT NTN TDD uplink subframe, and the solid box represents the IoT NTN TDD downlink subframe. A subframe includes one or more slots. The Iridium system downlink subframes span different radio frames in the nine NB-IoT radio frames, and the subframe numbers of the downlink active subframes are [3,4,5,6,7,8,9,0].

[0246] 1.2 Determine based on resource reservation configuration:

[0247] In some embodiments, if the higher-level parameter resourceReservationConfigDL is configured, for NPDSCH transmissions scrambled with C-RNTI using the UE-specific NPDCCH search space:

[0248] If the "Resource Reservation Field" in the DCI is set to 0, then the subframe is considered an NB-IoT downlink subframe.

[0249] If the "Resource Reservation Field" in DCI is set to 1, and if it is determined from higher-layer parameters that the subframe is not fully reserved, it will be regarded as an NB-IoT downlink subframe (a subframe is only considered fully reserved when all OFDM symbols in a subframe are reserved).

[0250] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value), but is not limited thereto.

[0251] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0252] In some embodiments, if the higher-level parameter resourceReservationConfigDL is configured, for NPDCCH transmissions scrambled with C-RNTI or SPSC-RNTI using the UE-specific NPDCCH search space:

[0253] If it is determined from higher-layer parameters that the subframe is not fully reserved, it is considered an NB-IoT downlink subframe (a subframe is considered fully reserved only when all orthogonal frequency division multiplexing (OFDM) symbols in a subframe are reserved).

[0254] 1.3 Determining by bitmap:

[0255] Downlink active subframes are subframes configured as usable downlink subframes using downlinkBitmapNonAnchor or downlinkBitmap-r13. In some embodiments, the subframes with a bitmap value of 1 in the aforementioned subframe numbers [3,4,5,6,7,8,9,0] are the downlink active subframes.

[0256] In some embodiments, the terms "search space", "search space set", "search space configuration", "search space set configuration", "control resource set (CORESET)", and "CORESET configuration" can be used interchangeably.

[0257] 1.4 Determine based on other conditions:

[0258] An NB-IoT UE should treat this subframe as an NB-IoT downlink subframe if the following conditions are met:

[0259] If an NB-IoT carrier has received the higher-layer parameter operationModeInfo, this subframe is configured as an NB-IoT downlink subframe;

[0260] or,

[0261] This subframe is a special TDD subframe configured for NB-IoT downlink transmission after the UE obtains SystemInformationBlockType1-NB.

[0262] 2. UE's rules for determining uplink subframes

[0263] The NB-IoT UE should determine whether a subframe is an NB-IoT uplink subframe according to the following rules:

[0264] 2.1 If the UE is operating in IoT-NTN TDD mode and the uplink subframe is within the uplink active period.

[0265] 2.2 If the high-level parameter resourceReservationConfigUL is already configured, further determination is required based on the resource reservation rules.

[0266] Step 2202: When terminal 101 is in time-division duplex mode, network device 102 sends GNSS signals to terminal 101 within the GNSS measurement gap.

[0267] In some embodiments, when the terminal 101 is in time-division duplex mode, the terminal 101 receives the global navigation satellite system signal sent by the network device 102 within the global navigation satellite system measurement gap.

[0268] Step 2203: The terminal 101 measures the global navigation satellite system signal to obtain information related to the global navigation satellite system.

[0269] In some embodiments, information related to the Global Navigation Satellite System includes at least one of the location information and time synchronization information of the terminal 101.

[0270] Figure 2D is a third exemplary interactive schematic diagram of a global navigation satellite system measurement method provided according to an embodiment of the present disclosure. As shown in Figure 2D, the embodiments of the present disclosure relate to a global navigation satellite system measurement method, which includes:

[0271] Step 2301: Network device 102 sends first information to terminal 101. The first information is used to indicate the GNSS measurement gap. The first information may indicate the start point of the GNSS measurement gap, the time period of the GNSS measurement gap, the period of the GNSS measurement gap, etc. The indication of the start point of the GNSS measurement gap may be an offset relative to the receiving time slot of the GNSS measurement gap indicating the MAC CE, or an offset of the time slot in which the UE feeds back ACK-NACK information for that MAC CE.

[0272] In some embodiments, if the Iridium system excludes the transmission of GNSS signals within its transmission time slots, the starting point and time period of the GNSS measurement gap are guaranteed to be in downlink active subframes (DNB-IoT subframes). This is equivalent to the Iridium system allocating some resources to terminal 101 and no longer occupying them itself. That is, the GNSS measurement gap includes Narrowband IoT downlink subframes.

[0273] In some embodiments, if the starting frame and subframe of the Global Navigation Satellite System (GNSS) measurement gap are not within the NB-IoT downlink subframe, the GNSS measurement gap should be postponed until the start of the next NB-IoT downlink subframe.

[0274] In some embodiments, dropped or delayed downlink channels (downlink slots / downlink subframes) are also included in the Global Navigation Satellite System measurement gaps.

[0275] In some embodiments, for NPUSCH of format 1 and 2, frame structure type 2, and Δf = 3.75 kHz, the NPUSCH transmission occurs in the first N... slots The NPUSCH transmission takes place within a set of time slots that span two consecutive uplink subframes and do not overlap with any uplink subframes configured as invalid. Under TDD configurations 1 and 4, if the start position of the NPUSCH is indicated as the second time slot in two consecutive uplink subframes, the NPUSCH transmission will be delayed until the start position of the two consecutive uplink subframes.

[0276] In some embodiments, if NPUSCH to N slots If, in a time slot mapping or its repeated mapping, there are resource elements that overlap with the target Narrow Band Physical Random Access Channel (NPRACH) resource, then:

[0277] For the N NPUSCH transmission with Δf = 3.75 kHz, slots If a time slot overlaps with a configured NPRACH resource, the transmission will be postponed to the next Nth time slot that does not overlap with any NPRACH resource. slots It is carried out in one time slot.

[0278] For the N USCH transmission where Δf = 15kHz is located slots If a time slot overlaps with the configured NPRACH resource, the transmission will be postponed to the next one, provided that the first time slot satisfies n s N mod 2 = 0, and does not overlap with any NPRACH resource slots It is carried out in one time slot.

[0279] The target NPRACH resource includes at least one of the following NPRACH resources:

[0280] Based on the NPRACH resources configured in nprach-ParametersList in SystemInformationBlockType2-NB;

[0281] If the UE supports multi-carrier NPRACH, the NPRACH resources are configured according to the nprach-ParametersList provided by ul-ConfigList in SystemInformationBlockType22-NB;
