Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a measurement method and apparatus, a communication method and apparatus, a terminal device, and a network device. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) has introduced Global Navigation Satellite System (GNSS) measurements in its research on non-terrestrial networks (NTNs). GNSS measurements can be used to determine the GNSS location of a terminal device.

[0003] The current NTN only considers sporadic and short-term data transmission services and performs GNSS measurements in the Radio Resource Control (RRC) idle state. Different from this, when the future NTN needs to consider long-term data transmission services, the terminal device may need to perform GNSS measurements in the RRC connected state. At the same time, the terminal device also needs to perform uplink transmission (such as uplink data transmission) in the RRC connected state. However, considering the complexity of the terminal device, the terminal device cannot perform GNSS measurement and uplink transmission at the same time in the RRC connected state. At this time, how the terminal device performs GNSS measurement in the RRC connected state to achieve GNSS measurement enhancement requires further research. Summary of the Invention

[0004] The present application provides a measurement method and apparatus, a communication method and apparatus, a terminal device, and a network device, in the hope of solving how a terminal device performs GNSS measurement in an RRC connected state, so as to achieve GNSS measurement enhancement.

[0005] The first aspect is a measurement method of the present application, comprising:

[0006] When the first valid duration ends and the terminal device can continue uplink transmission, GNSS measurement is performed according to the global navigation satellite system GNSS measurement starting position, the first valid duration represents the valid duration of the first GNSS position information of the terminal device, and the GNSS measurement is used to determine the second GNSS position information of the terminal device.

[0007] It can be seen that although the first effective duration has ended, the terminal device can still continue uplink transmission for a period of time in some scenarios. Therefore, when the first effective duration has ended and the terminal device can continue uplink transmission, since the terminal device cannot perform GNSS measurement and uplink transmission at the same time in the RRC connection state, this application needs to first determine the GNSS measurement starting position, and then perform GNSS measurement based on the GNSS measurement starting position, so as to achieve GNSS measurement enhancement.

[0008] The second aspect is a communication method of the present application, comprising:

[0009] Send first information, where the first information is used to configure the global navigation satellite system GNSS measurement starting position, and the GNSS measurement starting position is used to perform GNSS measurement when the first valid duration ends and the terminal device can continue uplink transmission. The first valid duration represents the valid duration of the first GNSS position information of the terminal device, and the GNSS measurement is used to determine the second GNSS position information of the terminal device.

[0010] It can be seen that although the first effective duration has ended, the terminal device can still continue uplink transmission for a period of time in some scenarios. Therefore, the present application can configure the GNSS measurement starting position to the terminal device through the first information. In this way, when the first effective duration has ended and the terminal device can continue uplink transmission, since the terminal device cannot perform NSS measurement and uplink transmission at the same time in the RRC connection state, the present application needs to first determine the GNSS measurement starting position, and then perform GNSS measurement based on the GNSS measurement starting position, thereby achieving GNSS measurement enhancement.

[0011] A third aspect is a measuring device of the present application, comprising:

[0012] A measurement unit is used to perform GNSS measurement according to the global navigation satellite system GNSS measurement starting position when the first valid duration ends and the terminal device can continue uplink transmission. The first valid duration represents the valid duration of the first GNSS position information of the terminal device, and the GNSS measurement is used to determine the second GNSS position information of the terminal device.

[0013] A fourth aspect is a communication device of the present application, comprising:

[0014] A sending unit is used to send first information, where the first information is used to configure a global navigation satellite system GNSS measurement starting position, where the GNSS measurement starting position is used to perform GNSS measurement when a first valid duration ends and the terminal device can continue uplink transmission, where the first valid duration indicates the valid duration of the first GNSS position information of the terminal device, and the GNSS measurement is used to determine the second GNSS position information of the terminal device.

[0015] In a fifth aspect, the steps in the method designed in the first aspect are applied to a terminal device or in a terminal device.

[0016] In a sixth aspect, the steps in the method designed in the second aspect are applied to a network device or in a network device.

[0017] The seventh aspect is a terminal device of the present application, comprising a processor, a memory, and a computer program or instructions stored on the memory, wherein the processor executes the computer program or instructions to implement the steps in the method designed in the above-mentioned first aspect.

[0018] The eighth aspect is a network device of the present application, comprising a processor, a memory, and a computer program or instructions stored on the memory, wherein the processor executes the computer program or instructions to implement the steps in the method designed in the second aspect above.

[0020] The tenth aspect is a chip module of the present application, comprising a transceiver component and a chip, wherein the chip comprises a processor, wherein the processor executes the steps in the method designed in the above-mentioned first aspect or second aspect.

[0021] The eleventh aspect is a computer-readable storage medium of the present application, wherein the computer-readable storage medium stores a computer program or instructions, and when the computer program or instructions are executed, the steps in the method designed in the first aspect or the second aspect are implemented.

[0071] It should be noted that satellites can be divided into low earth orbit (LEO) satellites, medium earth orbit (MEO) satellites, geostationary earth orbit (GEO) satellites and high elliptical orbit (HEO) satellites according to the different orbital altitudes. For example, the orbital altitude of LEO satellites is between 300km and 1700km. The orbital altitude of MEO satellites is between 7000km and 25000km. The orbital altitude of GEO satellites is 35786km. The orbital altitude of HEO satellites is between 400km and 50000km.

[0072] 4. Non-terrestrial network gateway

[0073] A non-terrestrial network gateway, which can be an earth station or gateway located on the ground, provides sufficient radio frequency (RF) power and RF sensitivity to connect ground-based devices (such as network equipment) to satellites. A non-terrestrial network gateway is a node in the transport network layer (TNL).

[0074] 5. Network equipment

[0075] A network device may be a device with transceiver functions and may be used to communicate with a terminal device.

For example, the network device includes a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU. Furthermore, in other embodiments of the present application, the network device may also include an active antenna unit (AAU). The CU implements part of the functions of the network device, and the DU implements another part of the functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, and implements the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, and implements the functions of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, RF processing, and related functions of the active antenna. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this network deployment, high-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or sent jointly by the DU and AAU. It is understood that network devices may include at least one of the CU, DU, and AAU. Furthermore, the CU may be classified as a RAN device, or as a core network device, without specific limitation.

[0090] 6. Explanation

[0091] For example, in the embodiment of the present application, a transparent satellite communication system is used as an example to illustrate the present application scheme. The transparent satellite communication system adopts a transparent payload. The schematic diagram of the transparent satellite communication system architecture is shown in FIG. Figure 2 As shown in the figure, the terminal device, non-terrestrial network gateway, and gNB are located on the Earth's surface, while the satellite is in Earth orbit. The satellite, non-terrestrial network gateway, and gNB form the NG-radio access network (NG-RAN). The NG-RAN connects to the 5G core network via the NG interface. The satellite and non-terrestrial network gateway can be considered remote radio equipment, and the satellite and non-terrestrial network gateway can communicate via the NR Uu interface.

[0092] 2. NTN Communication System

[0093] 1. NTN communication system and terrestrial network communication system

[0094] In NTN communication systems, satellites typically generate one or more beams (or beam footprints) within a given service area. These beams are typically elliptical in shape, as described in the 3GPP standard. Some satellites (such as LEO satellites) generate beams that move as they orbit. Conversely, some satellites (such as LEO or GEO satellites) generate beams on the ground that do not move as they orbit.

[0095] For example, Figure 3 As shown. Figure 3 In (a), the beam generated by a satellite (such as a LEO satellite or a GEO satellite) does not move as the satellite moves in a fixed orbit. Figure 3 In (b), the beam generated by the satellite moves as the satellite moves in a fixed orbit. Furthermore, when the relative distance between the satellite and the beam generated by the satellite is fixed, the path loss changes little.

[0096] Since the distance between the satellite and the ground is very far (for example, the GEO satellite is 35786km), the propagation distance between the terminal devices (such as UE) at different geographical locations and the satellite is relatively small within the coverage of the same beam or the same cell (that is, the path loss difference of the signal corresponding to the terminal devices at different geographical locations within the coverage of the same beam or the same cell is relatively small). As a result, the signal reception quality (including the downlink signal reception quality of the terminal devices) corresponding to the terminal devices at different geographical locations within the coverage of the same beam or the same cell is very small. For example, Figure 4 As shown in (b).

[0097] exist Figure 4 In the terrestrial network communication system shown in (a), there are terminal devices 4201 and 4202 at different geographical locations within the coverage area / cell of the same beam.

[0098] Since there is a large difference between the distance between the network device 410 and the terminal device 4201 and the distance between the network device 410 and the terminal device 4202, there is a large difference between the signal reception quality corresponding to the terminal device 4201 and the signal reception quality corresponding to the terminal device 4202. Figure 4 In the NTN communication system shown in (b), there are terminal devices 4401 and 4402 at different geographical locations within the coverage of the same beam / cell.

[0099] Since the distance between satellite 430 and the ground is very far, there is a small difference between the distance between satellite 430 and terminal device 4401, and the distance between satellite 430 and terminal device 4402, which leads to a small difference between the signal reception quality corresponding to terminal device 4401 and the signal reception quality corresponding to terminal device 4402.

[0100] 2. Architecture of NTN communication system

[0101] The architecture of the NTN communication system in the embodiment of the present application mainly includes an NTN communication architecture with a transparent satellite (i.e., using a transparent payload) and an NTN communication architecture with a regenerative satellite (i.e., using a regenerative payload). Figure 5 .in, Figure 5 (a) illustrates an NTN communication architecture with transparent satellites, while Figure 5 (b) illustrates an NTN communication architecture with regenerative satellites.

[0102] exist Figure 5 In (a), a satellite 510 in transparent forwarding mode generates at least one beam 520, and the at least one beam 520 can form a cell. A terminal device 530 located in the cell can measure the beams in the cell, select a beam based on the beam measurement results, and ultimately establish a communication connection with the satellite 510 via the selected beam.

[0103] exist Figure 5In (b), satellite 540 in regenerative signal mode generates at least one beam 550, and at least one beam 550 can form a cell. A terminal device 560 located in the cell can measure the beams in the cell, select a beam based on the beam measurement results, and ultimately establish a communication connection with satellite 540 via the selected beam.

[0104] 3. GNSS measurement

[0105] In NTN communication systems, terminal devices must obtain GNSS location information as a prerequisite for data transmission or uplink time advance synchronization. Therefore, when a terminal device has GNSS capabilities, it must perform GNSS measurements to obtain GNSS location information. Because terminal devices have high battery life requirements and typically only store a small amount of power / energy, frequent GNSS measurements should be avoided to minimize battery life and conserve energy.

[0106] It should be noted that the GNSS location information appearing in this application can be understood as terminal device location information (such as UE location information), GNSS positioning information, etc., and this information can be determined based on GNSS.

[0107] Since the current NTN only considers sporadic and short-term data transmission services, terminal devices do not need to remain in the RRC connected state for a long time. Therefore, terminal devices only need to complete GNSS measurements before entering the RRC connected state, and no GNSS measurements are required after entering the RRC connected state. If the GNSS position information becomes outdated during the RRC connected state, the terminal device needs to exit the RRC connected state and enter the idle state to re-determine the new GNSS position information.

[0108] In order to ensure the accuracy of GNSS position information during data transmission or RRC connection state, a validity duration (referred to as "GNSS validity duration") is defined for GNSS position information. In this way, during the GNSS validity duration, the terminal device and the network consider the GNSS position information to be valid and accurate. In addition, the terminal device can report the GNSS validity duration to the network. The value range of the GNSS validity duration can be {10s, 20s, 30s, 40s, 50s, 60s, 5min, 10min, 15min, 20min, 25min, 30min, 60min, 90min, 120min, infinity}.

[0109] In the NTN communication system, considering the complexity of terminal devices, terminal devices cannot perform GNSS measurement and uplink transmission simultaneously in the RRC connected state, that is, GNSS measurement and uplink transmission require time division.

[0110] For example, taking uplink transmission as an example, Figure 6 The basic process of uplink data transmission in the NTN communication system is given, in which GNSS measurement and uplink data transmission need to be separated in time.

[0111] 4. Uplink timing synchronization mechanism in NTN

[0112] In the current NTN communication system, it is assumed that the terminal device has GNSS positioning capabilities. In this way, the terminal device can calculate the round-trip time (RTT) between the terminal device's current location and the satellite based on ephemeris information and GNSS position information. Based on this, in the current NTN communication system, the TA (Timing Advance) value sent by the terminal device uplink is determined by the following parameters:

[0113] - The terminal-level TA value calculated by the terminal device based on the GNSS position information and ephemeris information, that is, the RTT between the terminal device and the satellite;

[0114] - The public TA value broadcast by the network, i.e. the RTT between the satellite and the reference point;

[0115] -TA adjustment value indicated by the network during random access via Message 2 (Msg2) or Message B (MsgB) or MAC CE (TA value does not include this parameter when sending PRACH);

[0116] -Fixed offset indicated by the network: N TA,offset .

[0117] 3. GNSS measurement enhancement process

[0118] 1. Description

[0119] Unlike the current NTN, which only performs GNSS measurements in the RRC Idle state for sporadic, short-term data transmission services, future NTNs, when considering long-term data transmission services, may require that terminal devices perform GNSS measurements in the RRC Connected state to enhance GNSS measurements. Furthermore, terminal devices will also need to perform uplink transmissions (e.g., uplink data transmission) in the RRC Connected state. However, given the complexity of terminal devices, they cannot perform GNSS measurements and uplink transmissions simultaneously; in other words, GNSS measurements and uplink transmissions must be time-divided.

[0120] Based on this, during the GNSS measurement enhancement process, in order to ensure that the terminal device can perform GNSS measurements during the RRC connection state, the network can configure the GNSS measurement time or GNSS measurement gap. During the GNSS measurement time, the terminal device can perform GNSS measurements. There are two ways to perform GNSS measurements:

[0121]

Method 1

[0122] In "Method 1," the network device can send a signaling message (such as MAC CE, RRC signaling, DCI, MAC signaling, etc.) within the GNSS validity period. This signaling message is used to trigger the terminal device to perform GNSS measurement. The terminal device then determines the starting position of the GNSS measurement gap based on the receiving location of the signaling message. At the same time, the network device also configures the length of the GNSS measurement gap. In this way, the starting position and length of the GNSS measurement gap can be used to determine the end position of the GNSS measurement gap.

[0123] For ease of description, this application will refer to the "starting position of the GNSS measurement gap" as the "GNSS measurement starting position." Additionally, in Method 1, the network device may also issue a signaling message (such as a MAC CE, RRC signaling, DCI, or MAC signaling) within the GNSS validity period. This signaling message is used to trigger the terminal device to perform GNSS measurements and directly indicate the GNSS measurement starting position.

[0124] Therefore, the starting position of the GNSS measurement can be determined by the terminal device or directly indicated by the network.

[0125] [Method 2]: The terminal device performs GNSS measurement independently

[0126] In "Method 2", when the GNSS valid period ends (expires, or is called "timeout") and the terminal device does not receive the trigger signaling sent by the network, the terminal device can determine the GNSS measurement starting position based on the end position of the GNSS valid period (also called the "timeout position of the GNSS valid period") and the network configured delay value (delay) (also called offset), so as to perform GNSS measurement based on the GNSS measurement starting position and realize autonomous execution of GNSS measurement.

[0127] The delay value can represent the time interval between the end position of the GNSS effective time and the start position of the GNSS measurement. At the same time, the network will also configure the length of the GNSS measurement gap, such as Figure 7 As shown. Figure 7The time interval between the end position of the GNSS effective time and the start position of the GNSS measurement is the delay value. [Continue uplink transmission]

[0128] In "Method 2", although the GNSS valid duration has expired, in some scenarios the terminal device can still continue uplink transmission for a period of time, such as time period X. For example, although the GNSS valid duration has expired, the uplink time and frequency error of the terminal device can still meet the uplink transmission requirements.

[0129] For the convenience of description, the present application may refer to "a period of time during which the terminal device can still continue uplink transmission" as "durantion during which the terminal device can continue uplink transmission".

[0130] For example, Figure 8 As shown in FIG, since the uplink time-frequency error of the terminal device can still meet the requirements of uplink transmission, when the GNSS effective time ends, the value of the time length for which the terminal device can continue uplink transmission is X.

[0131] In addition, whether the terminal device can continue uplink transmission after the GNSS validity period expires can be determined in the following two ways:

[0132] ◆The first method: based on the uplink timing alignment timer (TAC)

[0133] In the "first method", the network will configure a timing advance group (TAG) for each service cell of the terminal device, that is, each service cell will only belong to one TAG. In addition, in the maintenance of uplink time alignment, the network will configure a TAG to associate a TA value and / or a TAC timer, so that each service cell in the TAG will be associated with a TAC timer. Among them, the TAC timer can be used to control how long the terminal device believes that the service cell in the TAG associated with the TAC timer is uplink timing aligned. In other words, the TAC timer is associated with the TAG.

[0134] At this time, if the GNSS valid time has ended but the TAC timer has not timed out, the terminal device can continue uplink transmission.

[0135] ◆The second method: The network instructs the terminal device whether it can continue uplink transmission.

[0136] In the "second method", the network can indicate through signaling (such as MAC CE, DCI, RRC signaling, UE-specific signaling, MAC signaling, etc.) whether the terminal device can continue uplink transmission or not after the GNSS valid period ends, and configure the duration for which uplink transmission can continue.

[0137] In summary, in “Method 1”, the present application can determine the GNSS starting position based on the receiving position of the trigger signaling sent by the network in order to perform GNSS measurement.

[0138] In "Method 2", the present application can determine the GNSS measurement starting position based on the end position of the GNSS effective time and the delay value configured by the network in order to perform GNSS measurement.

[0139] In addition, in "Method 2", for the scenario where the GNSS validity period ends and the terminal device can continue uplink transmission, since the terminal device cannot perform GNSS measurement and uplink transmission at the same time in the RRC connected state, this application needs to first determine the GNSS measurement starting position. The GNSS measurement starting position and the time required for the terminal device to continue uplink transmission are divided. Then, GNSS measurement is performed based on the GNSS measurement starting position, thereby ensuring that the uplink transmission and GNSS measurement are separated in time, thereby achieving GNSS measurement enhancement.

[0140] [First GNSS position information, second GNSS position information, first validity period]

[0141] It should be noted that since the GNSS validity period can represent the validity period of the terminal device's original GNSS position information, when the GNSS validity period ends (also known as the GNSS validity period timeout), this indicates that the original GNSS position information is outdated, invalid, or inaccurate. At this time, the terminal device needs to perform GNSS measurement to determine the new GNSS position information.

[0142] For ease of distinction and description, this application may refer to the "original GNSS location information" as the "first GNSS location information," and the "new GNSS location information" as the "second GNSS location information." In other words, the GNSS validity period may represent the first GNSS location information of a terminal device, and the GNSS measurement is used to determine the second GNSS location information of the terminal device.

[0143] In addition, for ease of description, this application may refer to the "GNSS valid duration" as the "first valid duration", that is, the first valid duration may refer to the valid duration of the first GNSS position information of the terminal device. Of course, other terms may also be used for description.

[0144] 2. Specific implementation method

[0145] In "Method 2," in the scenario where the GNSS validity period has expired and the terminal device can continue uplink transmission, in order to determine the GNSS measurement starting position, this application will be specifically described from the following four embodiments. Of course, the contents of these embodiments may be interrelated, parallel, or independent of each other, and new embodiments may be formed based on the current example, without specific limitation.

[0146] Example 1:

[0147]

describe

[0148] Since the network configures the first effective duration and the duration during which the terminal device can continue to transmit to the terminal device, as well as the starting position of the first effective duration to the terminal device, the terminal device can determine the end position of the first effective duration based on the starting position of the first effective duration and the first effective duration. Therefore, in "Example 1", the present application can determine the GNSS measurement starting position based on the end position of the first effective duration, thereby facilitating the determination of the GNSS measurement starting position, so as to perform GNSS measurement based on the GNSS measurement starting position.

[0149] The end position of the first valid duration is before the start position of the GNSS measurement. In a specific implementation, the present application may introduce a first delay value, which may also be referred to as an offset. The first delay value may represent the time interval between the end position of the first valid duration and the start position of the GNSS measurement.

[0150] That is, the time interval between the end position of the first effective time length and the start position of the GNSS measurement is the first delay value.

[0151] In this way, the present application can determine the GNSS measurement starting position according to the end position of the first effective duration and the first delay value.

[0152] Optionally, the first delay value is greater than the duration during which the terminal device can continue uplink transmission. In other words, the time interval between the end position of the first effective duration and the start position of the GNSS measurement is greater than the duration during which the terminal device can continue uplink transmission.

[0153] This helps to ensure that GNSS measurement and uplink transmission are time-divided, that is, uplink transmission and GNSS measurement are separated in time.

[0154] For example, Figure 9 As shown, the time interval between the end position of the first effective time length and the starting position of the GNSS measurement is the first delay value Y, and the time length during which the terminal device can continue uplink transmission is X, Y>X.

[0155] Optionally, the first delay value may be configured using an implicit indication method or an explicit indication method, which will be described below respectively.

[0156]

Implicit indication method

[0157] The first delay value may be configured in an implicit indication manner, wherein the implicit indication manner may be that the first delay value is associated with a value of a duration during which the terminal device can continue uplink transmission.

[0158] In this way, when the terminal device obtains the value of the duration during which it can continue uplink transmission, the terminal device can determine the first delay value based on the value of the duration during which it can continue uplink transmission and the association relationship, thereby implicitly indicating the first delay value.

[0159] For example, if the network configures the terminal device to continue uplink transmission for a duration of X1, and its corresponding first delay value is Y1, the terminal device can determine Y1 based on X1, and then determine the GNSS measurement starting position based on the end position of the first effective duration and Y1.

[0160] Optionally, the association relationship may be defined by network configuration, pre-configuration, or protocol.

[0161] Optionally, different terminal devices may have the same associated first delay value for the duration of time during which they can continue uplink transmission.

[0162] In this way, the present application can configure a first delay value to different terminal devices or the same terminal device in an implicit indication manner, which is easy to implement in the network.

[0163] For example, when the network wishes to configure a first delay value for a certain cell or terminal device group, the network may configure different values ​​of the duration during which the terminal devices can continue uplink transmission, and associate them with a first delay value.

[0164] For another example, the network may configure a different value for the duration of uplink transmission continuation for the same terminal device each time. Although a different value for the duration of uplink transmission continuation is configured each time, the network only needs to configure the association once. The terminal device will continue to use the first delay value configured initially, thus reducing network complexity.

[0165] Optionally, different terminal devices may have the same associated first delay value for the duration of time during which they can continue uplink transmission.

[0166] In this way, the present application can configure the same first delay value to different terminal devices or the same terminal device in an implicit indication manner, which facilitates network implementation and reduces network complexity.

[0167] For example, when the network has multiple candidate first delay values ​​for a certain cell or terminal device group, the network can select one from the multiple candidate first delay values ​​and configure the selected first delay value to the cell or terminal device group.

[0168] For another example, the network configures different values ​​for the duration of uplink transmission continuation for the same terminal device each time. Although different values ​​for the duration of uplink transmission continuation are configured each time, the same first delay value can be configured each time based on the association relationship, thereby reducing network complexity.

[0169] Optionally, different terminal devices may have different associated first delay values ​​for the duration of time during which they can continue uplink transmission.

[0170] In this way, the present application can configure different first delay values ​​to different terminal devices or the same terminal device in an implicit indication manner, so as to improve network flexibility.

[0171] For example, when the network has multiple candidate first delay values ​​for a certain cell or terminal device group, the network can configure different first delay values ​​for each terminal device in the cell or terminal device group.

[0172] For another example, the network configures different values ​​for the duration of continued uplink transmission for the same terminal device each time, and can configure different first delay values ​​each time based on the association relationship, thereby improving network flexibility.

[0173]

Explicit indication method

[0174] The first delay value may be configured in an explicit indication manner, wherein the explicit indication manner may be to directly configure the first delay value for the network.

[0175] In this way, the network can directly configure the first delay value, so that the terminal device can determine the GNSS measurement starting position based on the end position of the first effective duration and the first delay value, thereby explicitly indicating the first delay value.

[0176] For example, the network may send a certain signaling (such as MAC CE, RRC signaling, DCI, MAC signaling, UE-specific signaling, etc.) to the terminal device, and the signaling is used to configure the first delay value.

[0177] Example 2:

[0178]

describe

[0179] Since the terminal device can know the starting position and the ending position of the duration for which it can continue uplink transmission, in "Example 2", the present application can determine the GNSS measurement starting position based on the ending position of the duration for which the terminal device can continue uplink transmission, thereby facilitating the determination of the GNSS measurement starting position so as to perform GNSS measurement based on the GNSS measurement starting position.

[0180] The end position of the duration during which the terminal device can continue uplink transmission is before the start position of the GNSS measurement, and the start position of the duration during which the terminal device can continue uplink transmission is the end position of the first valid duration.

[0181] In specific implementation, the present application may introduce a second delay value, which may also be referred to as an offset, wherein the second delay value may represent the time interval between the end position of the duration during which the terminal device can continue uplink transmission and the start position of the GNSS measurement.

[0182] That is to say, the time interval between the end position of the period during which the terminal device can continue uplink transmission and the starting position of the GNSS measurement is the second delay value.

[0183] In this way, the present application can determine the GNSS measurement starting position based on the end position of the duration during which the terminal device can continue uplink transmission and the second delay value. At the same time, since there is a time interval between the end position of the duration during which the terminal device can continue uplink transmission and the GNSS measurement starting position, that is, the time interval between the end position of the first effective duration and the GNSS measurement starting position is greater than the duration during which the terminal device can continue uplink transmission, it is beneficial to ensure that the GNSS measurement and uplink transmission are time-divided, that is, the uplink transmission and GNSS measurement are separated in time.

[0184] For example, Figure 10 As shown, the time interval between the end position of the duration during which the terminal device can continue uplink transmission and the starting position of the GNSS measurement is the second delay value Z, and the value of the duration during which the terminal device can continue uplink transmission is X.

[0185] Optionally, the second delay value may be configured using an implicit indication method or an explicit indication method, which will be described below respectively.

[0186]

Implicit indication method

[0187] The second delay value may be configured in an implicit indication manner, wherein the implicit indication manner may be that the second delay value is associated with a value of a duration during which the terminal device can continue uplink transmission.

[0188] In this way, when the terminal device obtains the value of the duration during which it can continue uplink transmission, the terminal device can determine the second delay value based on the value of the duration during which it can continue uplink transmission and the association relationship, thereby implicitly indicating the second delay value.

[0189] For example, if the network configures the terminal device to continue uplink transmission for a duration of X1, and its corresponding second delay value is Z1, the terminal device can determine Z1 based on X1, and then determine the GNSS measurement starting position based on the end position of the duration of the terminal device continuing uplink transmission and Z1.

[0190] Optionally, the association relationship may be defined by network configuration, pre-configuration, or protocol.

[0191] Optionally, different terminal devices may have the same associated second delay value for the duration of time during which they can continue uplink transmission.

[0192] In this way, the present application can configure a second delay value to different terminal devices or the same terminal device in an implicit indication manner, which is easy to implement in the network.

[0193] For example, when the network wishes to configure a second delay value for a certain cell or terminal device group, the network may configure different values ​​of the duration during which the terminal devices can continue uplink transmission, and associate a second delay value.

[0194] For another example, the network may configure a different value for the duration of uplink transmission continuation for the same terminal device each time. Although the value of the duration of uplink transmission continuation is different each time, the network only needs to configure the association once. The terminal device will continue to use the second delay value configured first each time, thereby reducing network complexity.

[0195] Optionally, different terminal devices may have the same associated second delay value for the duration of time during which they can continue uplink transmission.

[0196] In this way, the present application can configure the same first delay value to different terminal devices or the same terminal device in an implicit indication manner, which facilitates network implementation and reduces network complexity.

[0197] For example, when the network has multiple candidate first delay values ​​for a certain cell or terminal device group, the network can select one from the multiple candidate first delay values ​​and configure the selected first delay value to the cell or terminal device group.

[0198] For another example, the network configures different values ​​for the duration of uplink transmission continuation for the same terminal device each time. Although different values ​​for the duration of uplink transmission continuation are configured each time, the same first delay value can be configured each time based on the association relationship, thereby reducing network complexity.

[0199] Optionally, different terminal devices may have different associated second delay values ​​for the duration of time during which they can continue uplink transmission.

[0200] In this way, the present application can configure different second delay values ​​to different terminal devices or the same terminal device in an implicit indication manner, so as to improve network flexibility.

[0201] For example, when the network has multiple candidate second delay values ​​for a certain cell or terminal device group, the network can configure different second delay values ​​for each terminal device in the cell or terminal device group.

[0202] For another example, the network configures different values ​​for the duration of continued uplink transmission for the same terminal device each time, and can configure different second delay values ​​each time based on the association relationship, thereby improving network flexibility.

[0203]

Explicit indication method

[0204] The second delay value may be configured in an explicit indication manner, wherein the explicit indication manner may be used to directly configure the second delay value for the network.

[0205] In this way, the network can directly configure the first delay value, so that the terminal device can determine the GNSS measurement starting position based on the end position of the time period during which the terminal device can continue uplink transmission and the second delay value, thereby explicitly indicating the second delay value.

[0206] For example, the network may send a certain signaling (such as MAC CE, RRC signaling, DCI, MAC signaling, UE-specific signaling, etc.) to the terminal device, and the signaling is used to configure the second delay value.

[0207] Example 3:

[0208]

describe

[0209] Since the terminal device can know the timeout position of the uplink timing alignment timer, in "Example 3", the present application can determine the GNSS measurement starting position based on the timeout position of the uplink timing alignment timer, so as to facilitate determining the GNSS measurement starting position so as to perform GNSS measurement based on the GNSS measurement starting position.

[0210] The timeout position of the uplink timing alignment timer is before the GNSS measurement start position, and the timeout position of the uplink timing alignment timer is after the end position of the first valid duration.

[0211] In specific implementation, the present application may introduce a third delay value, which may also be called an offset, wherein the third delay value may represent the time interval between the timeout position of the uplink timing alignment timer and the GNSS measurement start position.

[0212] That is, the time interval between the timeout position of the uplink timing alignment timer and the GNSS measurement start position is the third delay value.

[0213] In this way, the present application can determine the GNSS measurement starting position based on the timeout position of the uplink timing alignment timer and the third delay value. At the same time, since there is a time interval between the timeout position of the uplink timing alignment timer and the GNSS measurement starting position, that is, the time interval between the end position of the first effective duration and the GNSS measurement starting position is greater than the duration that the terminal device can continue uplink transmission, it is beneficial to ensure that the GNSS measurement and uplink transmission are time-divided, that is, the uplink transmission and GNSS measurement are separated in time.

[0214] For example, Figure 11 As shown, the time interval between the timeout position of the uplink timing alignment timer and the GNSS measurement start position is the third delay value N, and the remaining duration of the uplink timing alignment timer at the end of the first valid duration is M, that is, the remaining duration value M.

[0215] Optionally, the third delay value may be configured using an implicit indication method or an explicit indication method, which will be described below respectively.

[0216]

Implicit indication method

[0217] The third delay value may be configured in an implicit indication manner, wherein the implicit indication manner may be that the third delay value is associated with a remaining duration value, where the remaining duration value indicates the value of the duration remaining in the uplink timing alignment timer after the first valid duration ends.

[0218] In this way, since the terminal device can know the timeout position of the uplink timing alignment timer and the end position of the first valid duration, the terminal device can obtain the remaining duration value, and then determine the third delay value based on the remaining duration value and the above-mentioned association relationship, thereby realizing the implicit indication of the third delay value.

[0219] For example, if the remaining duration value is M1 and its corresponding third delay value is N1, the terminal device can determine N1 based on M1, and then determine the GNSS measurement starting position based on the timeout position of the uplink timing alignment timer and N1.

[0220] Optionally, the association relationship may be defined by network configuration, pre-configuration, or protocol.

[0221] Optionally, different remaining duration values ​​may be associated with the same third delay value.

[0222] In this way, the present application can configure a third delay value to different terminal devices or the same terminal device in an implicit indication manner, which is easy to implement in the network.

[0223] For example, when the network wishes to configure a third delay value for a certain cell or terminal device group, the network may configure different remaining duration values ​​and associate them with a third delay value.

[0224] For another example, the same terminal device obtains different remaining time values. Although different remaining time values ​​are obtained each time, the network only needs to configure the association once, and the terminal device continues to use the third delay value configured for the first time each time, thereby reducing network complexity.

[0225] Optionally, different remaining duration values ​​are associated with the same third delay value.

[0226] In this way, the present application can configure the same third delay value to different terminal devices or the same terminal device in an implicit indication manner, which facilitates network implementation and reduces network complexity.

[0227] For example, when the network has multiple candidate third delay values ​​for a certain cell or terminal device group, the network can select one from the multiple candidate third delay values ​​and configure the selected third delay value to the cell or terminal device group.

[0228] For another example, the same terminal device obtains different remaining time values ​​each time. Although different remaining time values ​​are obtained each time, the same third delay value can be configured each time according to the association relationship, thereby reducing network complexity.

[0229] Optionally, different remaining duration values ​​are associated with different third delay values.

[0230] In this way, the present application can configure different third delay values ​​to different terminal devices or the same terminal device in an implicit indication manner, so as to improve network flexibility.

[0231] For example, when the network has multiple candidate third delay values ​​for a certain cell or terminal device group, the network can configure different third delay values ​​for each terminal device in the cell or terminal device group.

[0232] For another example, the same terminal device obtains a different remaining duration value each time, and can configure a different third delay value each time according to the association relationship, thereby improving network flexibility.

[0233]

Explicit indication method

[0234] The third delay value may be configured in an explicit indication manner, wherein the explicit indication manner may be used to directly configure the third delay value for the network.

[0235] In this way, the network can directly configure the third delay value, so that the terminal device can determine the GNSS measurement starting position based on the timeout position of the uplink timing alignment timer and the third delay value, thereby explicitly indicating the third delay value.

[0236] For example, the network may send a certain signaling (such as MAC CE, RRC signaling, DCI, MAC signaling, UE-specific signaling, etc.) to the terminal device, and the signaling is used to configure the third delay value.

[0237] Example 4:

[0238]

describe

[0239] Since the network will configure the first valid duration and the uplink timing alignment timer to the terminal device, the terminal device can know the starting position and end position of the first valid duration, as well as the timeout position of the uplink timing alignment timer. Therefore, in "Example 4", the present application can determine the GNSS measurement starting position based on the end position of the first valid duration, thereby facilitating the determination of the GNSS measurement starting position, so as to perform GNSS measurement based on the GNSS measurement starting position.

[0240] The end position of the first valid duration is before the start position of the GNSS measurement.

[0241] In a specific implementation, the present application may introduce a first delay value, which may also be referred to as an offset, wherein the first delay value may represent the time interval between the end position of the first effective duration and the start position of the GNSS measurement.

[0242] That is, the time interval between the end position of the first effective time length and the start position of the GNSS measurement is the first delay value.

[0243] In this way, the present application can determine the GNSS measurement starting position according to the end position of the first effective duration and the first delay value.

[0244] Optionally, the first delay value is greater than the value of the remaining duration of the uplink timing alignment timer at the end of the first effective duration. In other words, the time interval between the end position of the first effective duration and the start position of the GNSS measurement is greater than the duration for which the terminal device can continue uplink transmission.

[0245] This helps to ensure that GNSS measurement and uplink transmission are time-divided, that is, uplink transmission and GNSS measurement are separated in time.

[0246] For example, Figure 12 As shown, the time interval between the end position of the first effective duration and the starting position of the GNSS measurement is the first delay value Y, and the remaining duration of the uplink timing alignment timer at the end of the first effective duration is M, that is, the remaining duration value M, Y>M.

[0247] Optionally, the first delay value may be configured using an implicit indication method or an explicit indication method, which will be described below respectively.

[0248]

Implicit indication method

[0249] The first delay value may be configured in an implicit indication manner, wherein the implicit indication manner may be that the first delay value is associated with a remaining duration value, where the remaining duration value indicates the value of the duration remaining in the uplink timing alignment timer at the end of the first valid duration.

[0250] In this way, since the terminal device can know the timeout position of the uplink timing alignment timer and the end position of the first valid duration, the terminal device can obtain the remaining duration value, and then determine the first delay value based on the remaining duration value and the above-mentioned association relationship, thereby realizing implicit indication of the first delay value.

[0251] For example, if the terminal device obtains the remaining duration value M1 and its corresponding first delay value Y1, the terminal device can determine Y1 based on M1, and then determine the GNSS measurement starting position based on the end position of the first effective duration and Y1.

[0252] Optionally, the association relationship may be defined by network configuration, pre-configuration, or protocol.

[0253] Optionally, different remaining duration values ​​may be associated with the same first delay value.

[0254] In this way, the present application can configure a first delay value to different terminal devices or the same terminal device in an implicit indication manner, which is easy to implement in the network.

[0255] For example, when the network wishes to configure a first delay value for a certain cell or terminal device group, the network may configure different remaining duration values ​​and associate them with a first delay value.

[0256] For another example, the same terminal device obtains different remaining time values. Although different remaining time values ​​are obtained each time, the network only needs to configure the association once, and the terminal device continues to use the first delay value configured for the first time each time, thereby reducing network complexity.

[0257] Optionally, different remaining duration values ​​are associated with the same first delay value.

[0258] In this way, the present application can configure the same first delay value to different terminal devices or the same terminal device in an implicit indication manner, which facilitates network implementation and reduces network complexity.

[0259] For example, when the network has multiple candidate first delay values ​​for a certain cell or terminal device group, the network can select one from the multiple candidate first delay values ​​and configure the selected first delay value to the cell or terminal device group.

[0260] For another example, the same terminal device obtains different remaining time values ​​each time. Although different remaining time values ​​are obtained each time, the same first delay value can be configured each time according to the association relationship, thereby reducing network complexity.

[0261] Optionally, different remaining duration values ​​may have associated first delay values ​​that are different from each other.

[0262] In this way, the present application can configure different first delay values ​​to different terminal devices or the same terminal device in an implicit indication manner, so as to improve network flexibility.

[0263] For example, when the network has multiple candidate first delay values ​​for a certain cell or terminal device group, the network can configure different first delay values ​​for each terminal device in the cell or terminal device group.

[0264] For another example, the same terminal device obtains a different remaining time value each time, and can configure a different first delay value each time according to the association relationship, thereby improving network flexibility.

[0265]

Explicit indication method

[0266] The first delay value may be configured in an explicit indication manner, wherein the explicit indication manner may be to directly configure the first delay value for the network.

[0267] In this way, the network can directly configure the first delay value, so that the terminal device can determine the GNSS measurement starting position based on the end position of the first effective duration and the first delay value, thereby explicitly indicating the first delay value.

[0268] For example, the network may send a certain signaling (such as MAC CE, RRC signaling, DCI, MAC signaling, UE-specific signaling, etc.) to the terminal device, and the signaling is used to configure the first delay value.

[0269] 3. An illustrative description of a measurement method

[0270] 1) Description

[0271] In conjunction with the above content, the following describes an example of a measurement method according to an embodiment of the present application, which can be applied to a terminal device, wherein the terminal device can also be a chip / chip module / device, etc., without specific limitation.

[0272] like Figure 13 FIG. 1 is a flow chart of a measurement method according to an embodiment of the present application, which specifically includes the following steps:

[0273] S1310. When the first effective duration expires and the terminal device can continue uplink transmission, GNSS measurement is performed based on the GNSS measurement starting position. The first effective duration represents the effective duration of the first GNSS position information of the terminal device, and the GNSS measurement is used to determine the second GNSS position information of the terminal device. It should be noted that the details of "first effective duration," "GNSS position information," "terminal device can continue uplink transmission," "GNSS measurement starting position," etc. are described above and will not be repeated here.

[0274] It can be seen that although the first effective duration has ended, the terminal device can still continue uplink transmission for a period of time in some scenarios. Therefore, when the first effective duration has ended and the terminal device can continue uplink transmission, since the terminal device cannot perform GNSS measurement and uplink transmission at the same time in the RRC connection state, this application needs to first determine the GNSS measurement starting position, and then perform GNSS measurement based on the GNSS measurement starting position, so as to achieve GNSS measurement enhancement.

[0431] 1. Description

[0432] The above mainly introduces the solution of the embodiment of the present application from the perspective of the method side. It is understandable that, in order to implement the above functions, the network device includes a hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0433] The embodiments of the present application can divide the network device into functional units according to the above-mentioned method examples. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into a processing unit. The above-mentioned integrated unit can be implemented in the form of hardware or in the form of a software program module. It should be noted that the division of units in the embodiments of the present application is schematic and is only a logical functional division. In actual implementation, other division methods can be used.

[0434] In the case of an integrated unit, Figure 16 The communication device 1600 includes a transmitting unit 1601 .

[0435] It should be noted that the sending unit 1601 may be a module unit for sending information and the like.

[0436] Optionally, the communication device 1600 may further include a storage unit for storing computer program codes or instructions executed by the sending unit 1601. The storage unit may be a memory.

[0437] Optionally, the communication device 1600 may further include a communication unit, wherein the communication unit may be a communication interface, a transceiver, a transceiver circuit, etc.

[0438] Optionally, the communication device 1600 may be a chip or a chip module.

[0439] Optionally, the sending unit 1601 may be integrated into a processing unit.

[0442] Sending unit 1601 is used to send first information, which is used to determine the starting position of the global navigation satellite system GNSS measurement. The GNSS measurement starting position is used to perform GNSS measurement when the first valid time ends and the terminal device can continue uplink transmission. The first valid time indicates the valid time of the first GNSS position information of the terminal device. The GNSS measurement is used to determine the second GNSS position information of the terminal device.
