[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0040] Currently, relevant standards organizations are researching NTN technology, which generally uses satellite communication to provide communication services to terrestrial users. Compared to terrestrial cellular communication networks, satellite communication has many unique advantages. First, satellite communication is not limited by the user's geographical location. For example, conventional terrestrial communication cannot cover areas such as oceans, mountains, and deserts where communication equipment cannot be installed or where there is no communication coverage due to sparse population. However, for satellite communication, since a single satellite can cover a large area, and satellites can orbit the Earth, theoretically every corner of the Earth can be covered by satellite communication. Second, satellite communication has significant social value. Satellite communication can provide coverage in remote mountainous areas and impoverished countries or regions at a relatively low cost, enabling people in these areas to enjoy advanced voice communication and mobile internet technologies, helping to narrow the digital divide with developed regions and promoting development in these areas. Third, satellite communication has a long range, and the cost of communication does not increase significantly with increasing communication distance. Finally, satellite communication has high stability and is not affected by natural disasters.

[0041] Communication satellites are classified according to their orbital altitude into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit) satellites, HEO (High Elliptical Orbit) satellites, and so on. Currently, research primarily focuses on LEO and GEO.

[0042] 1. LEO

[0043] Low Earth orbit (LEO) satellites range in altitude from 500km to 1500km, with corresponding orbital periods of approximately 1.5 to 2 hours. The signal propagation delay for single-hop communication between users is generally less than 20ms. The maximum satellite visibility time is 20 minutes. The short signal propagation distance and low link loss mean that the requirements for the transmission power of user terminal equipment are not high.

[0044] 2. GEO

[0045] A geostationary orbit satellite, with an orbital altitude of 35,786 km, orbits the Earth every 24 hours. The signal propagation delay for single-hop communication between users is typically 250 ms.

[0046] To ensure satellite coverage and improve the overall capacity of the satellite communication system, satellites use multi-beam coverage to cover the ground. A single satellite can generate dozens or even hundreds of beams to cover the ground; a single satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0047] Please refer to Figure 1 This illustrates a schematic diagram of a satellite network architecture where communication satellites are transparent payload relay satellites. For example... Figure 1 As shown, the satellite network architecture includes: terminal equipment 10, satellite 20, NTN gateway 30, access network equipment 40, and core network equipment 50.

[0048] Terminal device 10 and access network device 40 can communicate via an air interface (such as a Uu interface). Figure 1 In the illustrated architecture, the access network device 40 can be deployed on the ground. Uplink and downlink communication between the terminal device 10 and the access network device 40 can be relayed via satellite 20 and NTN gateway 30 (usually located on the ground). Taking uplink transmission as an example, the terminal device 10 sends the uplink signal to satellite 20, satellite 20 forwards the uplink signal to NTN gateway 30, and then NTN gateway 30 forwards the uplink signal to access network device 40. Subsequently, access network device 40 sends the uplink signal to core network device 50. Taking downlink transmission as an example, the downlink signal from core network device 50 is sent to access network device 40, access network device 40 sends the downlink signal to NTN gateway 30, NTN gateway 30 forwards the downlink signal to satellite 20, and then satellite 20 forwards the downlink signal to terminal device 10.

[0049] Please refer to Figure 2 This illustrates a different satellite network architecture where communication satellites are regenerative payload relay satellites. Figure 2 As shown, the satellite network architecture includes: terminal equipment 10, satellite 20, NTN gateway 30, and core network equipment 50.

[0050] exist Figure 2In the architecture shown, the functions of the access network device 40 are integrated into the satellite 20, meaning that the satellite 20 possesses the functions of the access network device 40. The terminal device 10 and the satellite 20 can communicate via an air interface (such as a Uu interface). The satellite 20 and the NTN gateway 30 (usually located on the ground) can communicate via SRI (Satellite Radio Interface).

[0051] exist Figure 2 In the illustrated architecture, taking uplink transmission as an example, terminal device 10 sends uplink signals to satellite 20, satellite 20 forwards the uplink signals to NTN gateway 30, and then NTN gateway 30 forwards the uplink signals to core network device 50. Taking downlink transmission as an example, downlink signals from core network device 50 are sent to NTN gateway 30, NTN gateway 30 forwards the downlink signals to satellite 20, and then satellite 20 forwards the downlink signals to terminal device 10.

[0052] In the above Figure 1 and Figure 2 In the network architecture shown, access network device 40 is a device used to provide wireless communication services to terminal device 10. Access network device 40 and terminal device 10 can establish a connection to communicate, including signaling and data exchange. There can be multiple access network devices 40, and two adjacent access network devices 40 can communicate via wired or wireless means. Terminal device 10 can switch between different access network devices 40, that is, establish connections with different access network devices 40.

[0053] Taking a cellular communication network as an example, the access network device 40 in the cellular communication network can be a base station. A base station is a device deployed in the access network to provide wireless communication functions for the terminal device 10. Base stations can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions may differ; for example, in a 5G NR system, they are called gNodeB or gNB. As communication technologies evolve, the name "base station" may change. For ease of description, in this embodiment, the devices that provide wireless communication functions for the terminal device 10 are collectively referred to as base stations or access network devices.

[0054] Furthermore, the terminal device 10 involved in this application embodiment may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of user equipment (UE), mobile station (MS), terminal device, etc. For ease of description, the devices mentioned above are collectively referred to as terminal devices in this application embodiment. In some places in this application embodiment, "UE" is used to represent "terminal device". In this application embodiment, "network device" may be access network equipment (such as a base station) or a satellite.

[0055] Furthermore, taking a 5G NTN network as an example, an NTN network can include multiple satellites 20. One satellite 20 can cover a certain area of ​​the ground, providing wireless communication services to terminal devices 10 in that area. In addition, satellites 20 can orbit the Earth, and by deploying multiple satellites 20, communication coverage of different areas on the Earth's surface can be achieved.

[0056] Furthermore, in the embodiments of this application, the terms "network" and "system" are often used interchangeably, but those skilled in the art will understand their meanings. The technical solutions described in the embodiments of this application can be applied to LTE (Long Term Evolution) systems, 5G NR systems, subsequent evolution systems of 5G NR systems, or other communication systems, and this application does not limit them in this regard.

[0057] Before introducing the technical solution of this application, some background technical knowledge involved in this application will be introduced and explained.

[0058] 1. Timing Advance (TA)

[0059] A key characteristic of uplink transmission is orthogonal multiple access in time and frequency domains for different terminal devices, meaning that uplink transmissions from different terminal devices originating from the same serving cell do not interfere with each other. To ensure the orthogonality of uplink transmissions and avoid intra-cell interference, network devices require that signals from different terminal devices originating from the same time but using different frequency domain resources arrive at the network device at essentially the same time. To ensure time synchronization on the network device side, NR supports an uplink timing advance mechanism.

[0060] By appropriately controlling the offset of each terminal device, network devices can control the arrival time of uplink signals from different terminal devices. For terminal devices farther from the network device, due to the greater transmission delay, uplink data must be sent earlier than for terminal devices closer to the network device.

[0061] Network devices determine the TA (Target Acquisition) of each terminal device based on the uplink transmissions of the measurement terminal devices.

[0062] 2. Timing Advance Group (TAG)

[0063] In carrier aggregation (CA) scenarios, terminal devices use different TAs for different uplink carriers, hence the concept of TAGs is introduced in the standard. The network configures up to four TAGs for each serving cell group of the terminal device, and also configures an associated TAG for each serving cell. The terminal device selects the TA in the TAG corresponding to the serving cell from which it transmits, with each TAG corresponding to one TA.

[0064] 3. Offset value Koffset

[0065] In NR systems, after a terminal device receives an uplink grant from the network device scheduling information in downlink time slot n, it transmits uplink data in uplink time slot n+K, where K is the uplink resource time slot offset supported in the uplink grant, used to determine the time domain resource location for uplink transmission. In NTN networks, due to significantly increased transmission delays, the uplink timing advance of the terminal device increases significantly, causing the range of values ​​for K in the NR system to fail to meet the normal timing requirements of uplink and downlink transmissions. Therefore, the offset value Koffset is introduced to address this issue.

[0066] For example, the transmission timing of the Physical Uplink Shared Channel (PUSCH) scheduled by Downlink Control Information (DCI) is as follows: Figure 3 As shown: If the terminal device receives the scheduling DCI in downlink time slot n, then the time slot allocated for PUSCH transmission is the uplink time slot. The introduction of Koffset ensures that the terminal device can send PUSCH at the specified time after receiving the DCI (Distributed Control Information Center). Here, the role of Koffset is that without it, according to the NR (Normative Radio System)... After the TA mechanism, the time slot for the terminal to transmit PUSCH was actually before the DCI reception, indicating a clear timing error. Here, K2 is the time slot indicated in the DCI scheduling, μ PUSCH and μ PDCCH These are used to determine the subcarrier spacing configured for PUSCH and PDCCH, respectively. The value of K2 ranges from 0 to 32.

[0067] For example, the transmission timing of PUSCHs scheduled by Random Access Response (RAR) grant: For a time slot scheduled for PUSCH transmission by RAR grant, the terminal device in time slot n+K2+Δ+K offset The PUSCH is transmitted uplink. The value of K2 is indicated by the uplink grant in the RAR, and Δ is a value agreed upon in the protocol.

[0068] For example, the transmission timing of Hybrid Automatic Repeat reQuest (HARQ) - Acknowledgement (ACK) on PUCCH: For a PUCCH transmission slot, the terminal device should transmit in slot n+K1+ offset The corresponding HARQ-ACK information is transmitted on the Physical Uplink Control Channel (PUCCH) resources within the DCI. Here, K1 is the number of time slots, indicated by the PDSCH-to-HARQ-timing-indicator field in the DCI format, or provided by the dl-DataToUL-ACK parameter. K1 = 0 corresponds to the last time slot of PUCCH transmission overlapping with the time slot of PDSCH reception or the time slot of Physical Downlink Control Channel (PDCCH) reception indicating semi-static scheduling (SPS) PDSCH release.

[0069] For example, the Media Access Control Element (MAC CE) activation timing: when the HARQ-ACK information corresponding to the PDSCH including the MAC CE command is transmitted on time slot n, the corresponding behavior indicated by the MAC CE command and the downlink configuration assumed by the terminal device should be generated from the time slot. The first time slot after that takes effect, where X may be determined by the NTN's terminal device capabilities. This indicates the number of time slots included in each subframe under the subcarrier spacing configuration μ.

[0070] For example, Channel State Information (CSI) reference resource timing: For CSI reference resources reported in uplink time slot n′, it is based on a single downlink time slot. It is certain. Among them, μ DL and μ ULThese are the subcarrier spacing configurations for downlink and uplink, respectively. CSI_ref The value depends on the type of CSI report.

[0071] For example, the timing of aperiodic SRS transmission: If the terminal device receives a DCI-triggered aperiodic SRS transmission in downlink time slot n, the terminal device will transmit the aperiodic SRS in the uplink time slot. The uplink transmits aperiodic SRS in each triggered SRS resource set. Here, k is configured by the higher-layer parameter (slotOffset) in each triggered SRS resource set and is determined according to the subcarrier spacing corresponding to the triggered SRS transmission, μ... SRS and μ PDCCH These are the subcarrier spacing configurations for the triggered SRS transmission and the PDCCH carrying the trigger command, respectively.

[0072] 4. Koffset configuration

[0073] Currently, networks primarily refer to the TA (Target Acquisition Context) to configure the Koffset value. For example, the koffset is configured based on the maximum TA supported by the cell or a satellite beam, or a dedicated Koffset is configured for the terminal device by referring to its TA.

[0074] In NTN CA scenarios, such as when GEO and LEO use CA for networking, the TA used by terminal devices will vary significantly for different serving cells. If only one Koffset is configured for a terminal device and applied to all serving cells, it will cause unnecessary uplink scheduling delays for those serving cells with smaller actual TAs.

[0075] Please refer to Figure 4 The diagram illustrates a flowchart of a timing parameter configuration method provided in an embodiment of this application. This method can be executed by a terminal device and may include the following steps:

[0076] Step 410: Receive timing parameter configuration information sent by the network device. The timing parameter configuration information is used to determine the time domain resources for uplink transmission on the terminal device.

[0077] The timing parameter configuration information is used to indicate the Koffset used by the terminal device in the serving cell, so that the offset value Koffset used by the terminal device in different serving cells matches the timing advance value TA used by the terminal device in different serving cells.

[0078] For example, the timing parameter configuration information is used to indicate the Koffset of the terminal device in one serving cell; or, the timing parameter configuration information is used to indicate the Koffset of the terminal device in multiple serving cells, that is, to indicate the Koffset of the terminal device in different serving cells.

[0079] Here, the terminal device corresponds to multiple serving cells, but the network can either configure Koffset for only some of the multiple serving cells, or configure Koffset for all of the multiple serving cells.

[0080] Here, Koffset is the time offset, and the unit can be set to various time units in the time domain as needed, such as time slots.

[0081] In the scheme provided in this application, configuring a Koffset for a serving cell by the network means configuring at least one of a public Koffset and a terminal-specific Koffset for the serving cell, while not configuring a Koffset for a serving cell by the network means neither configuring a public Koffset nor a terminal-specific Koffset.

[0082] Typically, when a network configures Koffset for all serving cells, the common Koffset for all serving cells is a mandatory configuration. Conversely, when a network configures Koffset for only some serving cells, the common Koffset for the serving cells is an optional configuration.

[0083] The timing parameter configuration information is used to indicate at least one of the following: the common Koffset of the serving cell of the terminal device, and the terminal-specific Koffset of the terminal device in at least one serving cell.

[0084] For example, the timing parameter configuration information is used to indicate the common Koffset of at least one serving cell among the multiple serving cells of the terminal device. That is, the timing parameter configuration information is used to indicate the common Koffset of one serving cell among the multiple serving cells of the terminal device, or the timing parameter configuration information is used to indicate the common Koffset of multiple serving cells among the multiple serving cells of the terminal device.

[0085] Similarly, timing parameter configuration information is used to indicate the terminal-specific Koffset of the terminal device in a serving cell, or timing parameter configuration information is used to indicate the terminal-specific Koffset of the terminal device in each of multiple serving cells.

[0086] The common Koffset configured by the network for a serving cell refers to the Koffset that the network shares with all terminal devices that use that cell as a serving cell. The network can configure a common Koffset for each serving cell.

[0087] A terminal-specific Koffset refers to the Koffset assigned by the network to a specific terminal device for a particular serving cell. The network can assign different terminal-specific Koffsets to different terminal devices for the same serving cell.

[0088] When determining the Koffset of the serving cell, the terminal device first checks whether the network has configured a terminal-specific Koffset for the serving cell. If so, the terminal-specific Koffset configured by the network for the serving cell is used; otherwise, the common Koffset configured by the network for the serving cell is used.

[0089] In an exemplary embodiment, there may be one or more public Koffsets for each serving cell.

[0090] When there is only one common Koffset, it is a cell-level common Koffset.

[0091] When there are multiple common Koffsets, the common Koffset is the common Koffset at the satellite beam level within the serving cell range.

[0092] In this context, a satellite beam refers to the shape formed on the Earth's surface by the electromagnetic waves emitted by a satellite's antenna. Each satellite corresponds to at least one satellite beam, different satellite beams correspond to different coverage areas, adjacent satellite beams may have partially overlapping coverage areas, and each satellite beam corresponds to at least one synchronization signal block (SSB).

[0093] In a CA scenario, the network can configure multiple TAGs for terminal devices. Different TAGs can use different TAs. One serving cell corresponds to one TAG. Therefore, in an NTN network, the terminal-specific Koffset can be configured either for the corresponding TAG or for the corresponding serving cell.

[0094] For example, the terminal-specific Koffset is the terminal-specific Koffset of the terminal device's TAG, and each serving cell is associated with one TAG;

[0095] Alternatively, the terminal-specific Koffset is the terminal-specific Koffset of the serving cell of the terminal device.

[0096] In this embodiment, the timing parameter configuration information indicates the terminal-specific Koffset of the terminal device's TAG in the following manner:

[0097] The first type is the indicator method corresponding to the TAG.

[0098] The timing parameter configuration information includes the Koffset corresponding to each TAG in at least one TAG of the terminal device; for example, the timing parameter configuration information includes a terminal-specific Koffset configured for each TAG in all TAGs of the terminal device. In this case, the Koffset and TAG are one-to-one. As another example, the timing parameter configuration information includes a terminal-specific Koffset configured for each TAG in some TAGs of the terminal device, while no terminal-specific Koffset is configured for another part of the terminal device. The serving cells corresponding to these TAGs without terminal-specific Koffsets use the common Koffset.

[0099] Alternatively, the timing parameter configuration information includes a Koffset list, which contains multiple Koffsets. Each TAG in at least one TAG of the terminal device is associated with a Koffset in the Koffset list. Similarly, the Koffset list method can be used to configure terminal-specific Koffsets for all TAGs of the terminal device, or only for some TAGs.

[0100] Here, the Koffset list and TAG can be associated in two ways:

[0101] 1. Implicit Association Method

[0102] The timing parameter configuration information only includes a list of Koffsets. Multiple Koffsets in the list are arranged in order, and this order matches the order of their corresponding tags.

[0103] For example, the terminal is configured with a TAG list, and the length of the TAG list and the length of the Koffset list are the same. There is a one-to-one correspondence between the TAGs in the TAG list and the Koffsets in the Koffset list. The i-th TAG in the TAG list corresponds to the i-th Koffset in the Koffset list, where i is a positive integer and does not exceed the length of the TAG list.

[0104] 2. Explicit Association Method

[0105] In addition to the Koffset list, the timing parameter configuration information also includes the association between Koffset and TAG in the Koffset list.

[0106] For example, which Koffset in the Koffset list each TAG is associated with, or at least one TAG associated with each Koffset in the Koffset list.

[0107] In explicit association, the number of Koffset and TAG can be equal or unequal.

[0108] For example, the number of Koffsets may be less than the number of TAGs. When all TAGs on a terminal device are configured with terminal-specific Koffsets, there may be a situation where one Koffset corresponds to more than one TAG, that is, in this case, there is a one-to-many relationship between Koffsets and TAGs.

[0109] The second method is the instruction method corresponding to the service cell.

[0110] The timing parameter configuration information includes the Koffset corresponding to each serving cell in at least one serving cell of the terminal device; for example, the timing parameter configuration information includes a terminal-specific Koffset configured for each serving cell of all serving cells of the terminal device. In this case, the Koffset and the serving cell are one-to-one. As another example, the timing parameter configuration information includes a terminal-specific Koffset configured for each serving cell in some serving cells of the terminal device, while not configuring a terminal-specific Koffset for another part of the serving cells of the terminal device. These serving cells that do not have a terminal-specific Koffset configured use a common Koffset.

[0111] Alternatively, the timing parameter configuration information includes a Koffset list, which contains multiple Koffsets. Each serving cell in at least one serving cell of the terminal device is associated with a Koffset in the Koffset list. Similarly, the Koffset list can be used to configure terminal-specific Koffsets for all serving cells of the terminal device, or only for some serving cells.

[0112] Similarly, the Koffset list and the serving cell also have two association methods: implicit and explicit. For details, please refer to the association section of Koffset list and TAG, which will not be elaborated here.

[0113] The timing parameter configuration method provided in this application enables the terminal device to determine the Koffset used by each serving cell based on the parameter configuration information. The offset value Koffset used by the terminal device in different serving cells is matched with the timing advance value TA used by the terminal device in different serving cells, thereby avoiding uplink scheduling delay caused by all serving cells using the same Koffset and improving network communication quality.

[0114] Please refer to Figure 5 The diagram illustrates a flowchart of a timing parameter configuration method provided in an embodiment of this application. This method can be executed by a network device and may include the following steps:

[0115] Step 510: Send timing parameter configuration information to the terminal device. The timing parameter configuration information is used to determine the time domain resources for uplink transmission on the terminal device.

[0116] The timing parameter configuration information is used to indicate the Koffset used by the terminal device in the serving cell, so that the offset value Koffset used by the terminal device in different serving cells matches the timing advance value TA used by the terminal device in different serving cells.

[0117] For details on how to configure the parameter configuration information, please refer to step 410.

[0118] The timing parameter configuration method provided in this application enables the terminal device to determine the Koffset used by each serving cell based on the parameter configuration information. The offset value Koffset used by the terminal device in different serving cells is matched with the timing advance value TA used by the terminal device in different serving cells, thereby avoiding uplink scheduling delay caused by all serving cells using the same Koffset and improving network communication quality.

[0119] Please refer to Figure 6 The diagram illustrates a flowchart of a timing parameter configuration method provided in an embodiment of this application. This method can be executed jointly by a terminal device and a network device, and may include the following steps:

[0120] Step 610: The network device generates timing parameter configuration information, which is used to determine the time domain resources for uplink transmission of the terminal device.

[0121] The timing parameter configuration information is used to indicate the offset value Koffset used by the terminal device in different serving cells, so that the offset value Koffset used by the terminal device in different serving cells matches the timing advance value TA used by the terminal device in different serving cells.

[0122] For details on how to configure the parameter configuration information, please refer to step 410.

[0123] In an exemplary implementation, the network device determines the common Koffset and terminal-specific Koffset of each serving cell based on the TA of each serving cell of the terminal device.

[0124] When determining the Koffset, it is necessary to ensure that the Koffset is not less than the TA of the corresponding serving cell. For example, the public Koffset of a serving cell is not less than the maximum TA within the coverage area of ​​that serving cell, and the terminal-specific Koffset of a terminal device in a serving cell is not less than the TA of the terminal in that serving cell.

[0125] For example, the public Koffset of a serving cell is equal to the maximum TA within the coverage area of ​​that serving cell, and the terminal-specific Koffset of a terminal device in a serving cell is equal to the TA of the terminal in that serving cell.

[0126] Step 620: The network device sends timing parameter configuration information to the terminal device. The terminal device receives the timing parameter configuration information sent by the network device.

[0127] As mentioned earlier, the timing parameter configuration information includes two parts: a common Koffset and a terminal-specific Koffset. When the network device sends the parameter configuration information to the terminal device, the common Koffset and the terminal-specific Koffset can be sent separately.

[0128] In an exemplary implementation, the public Koffset is sent as follows:

[0129] For the primary serving cell of the terminal device, the network device sends the common Koffset of the serving cell to the terminal device via broadcast; the terminal device receives the common Koffset of the serving cell sent by the network device via broadcast.

[0130] For the secondary serving cell of the terminal device, the network device sends the common Koffset of the serving cell to the terminal device via broadcast or dedicated Radio Resource Control (RRC) signaling; the terminal device receives the common Koffset of the serving cell sent by the network device via broadcast or unicast.

[0131] Broadcasting can be implemented through System Information Block (SIB), Master Information Block (MIB), etc., while unicasting can be implemented through dedicated RRC signaling, MAC CE signaling, or PDCCH signaling, etc.

[0132] The primary serving cell is the primary cell (Psell), and the secondary serving cell is the secondary cell (Scell).

[0133] Of course, the solution provided in this application is also applicable to the Master Cell group (MCG) and Secondary Cell group (SCG) in the dual connectivity (DC) scenario. In the DC scenario, the primary serving cell can be the primary secondary cell (PScell).

[0134] In an exemplary implementation, the terminal-specific Koffset is sent in the following manner:

[0135] The network device sends a terminal-specific Koffset for the serving cell to the terminal device via UE-specific signaling; the terminal device receives the terminal-specific Koffset for the serving cell sent by the network device via UE-specific signaling.

[0136] For example, UE-specific signaling may be dedicated RRC signaling, MAC CE signaling, or PDCCH signaling.

[0137] Step 630: The terminal device determines the Koffset used by the terminal device on each serving cell based on the timing parameter configuration information.

[0138] In an exemplary implementation, the terminal device determines the Koffset used in each serving cell as follows:

[0139] If a terminal-specific Koffset is configured for the first serving cell in the timing parameter configuration information, then the terminal-specific Koffset corresponding to the first serving cell will be determined as the Koffset used by the terminal device in the first serving cell. The first serving cell can be any serving cell.

[0140] If the timing parameter configuration information does not configure a terminal-specific Koffset for the first serving cell, then the common Koffset configured for the first serving cell in the timing parameter configuration information will be determined as the Koffset used by the terminal device in the first serving cell.

[0141] In an exemplary embodiment, the terminal device determines the common Koffset of the first serving cell in the following manner:

[0142] If the timing parameter configuration information for the first serving cell is a cell-level common Koffset, then the cell-level common Koffset configured for the first serving cell will be determined as the Koffset used by the terminal device in the first serving cell.

[0143] If the timing parameter configuration information for the first serving cell is configured with a common Koffset at the satellite beam level, then the common Koffset at the satellite beam level corresponding to the satellite beam where the terminal device is located in the satellite beam corresponding to the first serving cell is determined as the Koffset used by the terminal device in the first serving cell.

[0144] For example, if there are multiple satellite beams within the range of serving cell 1, and the terminal device is located on satellite beam 1 of serving cell 1, then the Koffset used by the terminal device in serving cell 1 is determined to be the common Koffset at the satellite beam level corresponding to satellite beam 1 configured for serving cell 1.

[0145] If the timing parameter configuration information does not configure a common Koffset for the first serving cell, then the terminal-specific Koffset or common Koffset configured for the primary serving cell of the terminal device will be determined as the Koffset used by the terminal device in the first serving cell.

[0146] Alternatively, if the timing parameter configuration information does not specify a common Koffset for the first serving cell, then the largest terminal-specific Koffset or the largest common Koffset configured for all second serving cells associated with the TAG corresponding to the first serving cell will be determined as the Koffset used by the terminal device in the first serving cell. The second serving cell is any serving cell associated with that TAG other than the first serving cell.

[0147] Here, the terminal-specific Koffset or public Koffset configured for the primary serving cell of the terminal device, which is determined as the Koffset used by the terminal device in the first serving cell, can include the following:

[0148] The first method is to directly determine the public Koffset configured for the primary serving cell of the terminal device as the Koffset used by the terminal device in the first serving cell.

[0149] The second approach is that when a terminal-specific Koffset is configured for the primary serving cell of the terminal device, the terminal-specific Koffset configured for the primary serving cell of the terminal device will be determined as the Koffset used by the terminal device in the first serving cell; if no terminal-specific Koffset is configured for the primary serving cell of the terminal device, then the public Koffset configured for the primary serving cell of the terminal device will be determined as the Koffset used by the terminal device in the first serving cell.

[0150] Here, the largest terminal-specific Koffset or the largest common Koffset configured for all second-serving cells associated with the TAG corresponding to the first serving cell refers to the largest terminal-specific Koffset among all terminal-specific Koffsets configured for all second-serving cells associated with the TAG corresponding to the first serving cell, or the largest common Koffset among all common Koffsets configured for all second-serving cells associated with the TAG corresponding to the first serving cell.

[0151] The following examples illustrate the timing parameter configuration method provided in this application:

[0152] Example 1: The timing parameter configuration information is as follows: For each serving cell of the terminal device, a cell-level common Koffset is configured. For the terminal device's TAG1, a terminal-specific Koffset1 is configured. For the terminal device's TAG2, a terminal-specific Koffset2 is configured. For the terminal device's TAG3, no terminal-specific Koffset is configured.

[0153] Based on the timing parameter configuration information, the terminal device determines that the serving cell associated with TAG1 uses the terminal-specific Koffset1, the serving cell associated with TAG2 uses the terminal-specific Koffset2, and each serving cell associated with TAG3 uses the common Koffset corresponding to that serving cell.

[0154] Example 2: The timing parameter configuration information configures a cell-level common Koffset for each serving cell of the terminal device, a TAG list for a serving cell group of the terminal device, including TAG1, TAG2 and TAG3, and a Koffset list for a serving cell group of the terminal device, including terminal-specific Koffset1 and terminal-specific Koffset2, and instructs TAG1 and TAG2 to be associated with terminal-specific Koffset1, and TAG3 to be associated with terminal-specific Koffset2.

[0155] Based on the timing parameter configuration information, the terminal device determines that the serving cell associated with TAG1 uses terminal-specific Koffset1, the serving cell associated with TAG2 uses terminal-specific Koffset1, and the serving cell associated with TAG3 uses terminal-specific Koffset2.

[0156] Example 3: Timing parameter configuration information: For each serving cell of the terminal device, a cell-level common Koffset is configured. For serving cell 1 of the terminal device, a terminal-specific Koffset1 is configured. For serving cell 2 of the terminal device, a terminal-specific Koffset2 is configured. For serving cell 3 of the terminal device, no terminal-specific Koffset is configured.

[0157] Based on the timing parameter configuration information, the terminal device determines that serving cell 1 uses terminal-specific Koffset1, serving cell 2 uses terminal-specific Koffset2, and serving cell 3 uses the common Koffset of serving cell 3.

[0158] Example 4: The timing parameter configuration information configures a cell-level common Koffset for each serving cell of the terminal device, a serving cell list for a serving cell group of the terminal device, including Pcell1, Scell1 and Scell2, and a Koffset list for a serving cell group of the terminal device, including terminal-specific Koffset1 and terminal-specific Koffset2, and instructs Pcell1 and Scell1 to be associated with terminal-specific Koffset1, and Scell2 to be associated with terminal-specific Koffset2.

[0159] Based on this timing parameter configuration information, the terminal device determines that Pcell1 uses terminal-specific Koffset1, Scell1 uses terminal-specific Koffset1, and Scell2 uses terminal-specific Koffset2.

[0160] Using the solution provided in this application, in a CA scenario, the network can flexibly configure multiple Koffsets for terminal devices according to the actual deployment, so that the Koffset used by the terminal device in each serving cell can better match the TA used by the terminal device for that serving cell, effectively reducing uplink scheduling latency and improving data transmission efficiency.
