Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

Currently, the related standards organization is researching NTN technology, which generally provides communication services to terrestrial users by adopting a satellite communication mode. Satellite communications have many unique advantages over terrestrial cellular communication networks. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit, geosynchronous Orbit) satellites, HEO (High Elliptical Orbit ) satellites, and the like according to the difference in Orbit heights. LEO and GEO are the main studies at the present stage.

1、LEO

The low orbit satellite has a height ranging from 500km to 1500km and a corresponding orbit period of about 1.5 hours to 2 hours. The signal propagation delay for single hop communications between users is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal equipment is not high.

2、GEO

Geosynchronous orbit satellites have an orbit height of 35786km and a period of 24 hours around the earth. The signal propagation delay for single hop communications between users is typically 250ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

Referring to fig. 1, a schematic diagram of a satellite network architecture is shown, in which the communication satellites are transparent forwarding (transparent payload) satellites. As shown in fig. 1, the satellite network architecture includes: terminal equipment 10, satellites 20, NTN gateway 30, access network equipment 40 and core network equipment 50.

Communication between the terminal device 10 and the access network device 40 may be performed via an air interface, such as the Uu interface. In the architecture shown in fig. 1, the access network device 40 may be deployed on the ground, and uplink and downlink communications between the terminal device 10 and the access network device 40 may be relayed through the satellite 20 and the NTN gateway 30 (typically located on the ground). Taking uplink transmission as an example, the terminal device 10 sends an uplink signal to the satellite 20, the satellite 20 forwards the uplink signal to the NTN gateway 30, the NTN gateway 30 forwards the uplink signal to the access network device 40, and the access network device 40 subsequently sends the uplink signal to the core network device 50. Taking downlink transmission as an example, the downlink signal from the core network device 50 is sent to the access network device 40, the access network device 40 sends the downlink signal to the NTN gateway 30, the NTN gateway 30 forwards the downlink signal to the satellite 20, and the satellite 20 forwards the downlink signal to the terminal device 10.

Referring to fig. 2, a schematic diagram of another satellite network architecture is shown, in which the communication satellites are regenerative forwarding (regenerative payload) satellites. As shown in fig. 2, the satellite network architecture includes: a terminal device 10, a satellite 20, an NTN gateway 30 and a core network device 50.

In the architecture shown in fig. 2, the functionality of the access network device 40 is integrated on the satellite 20, i.e. the satellite 20 is provided with the functionality of the access network device 40. Communication between the terminal device 10 and the satellite 20 may be via an air interface, such as the Uu interface. Communication between the satellites 20 and the NTN gateway 30 (typically located on the ground) may be via SRI (Satellite Radio Interface ).

In the architecture shown in fig. 2, taking uplink transmission as an example, the terminal device 10 sends an uplink signal to the satellite 20, the satellite 20 forwards the uplink signal to the NTN gateway 30, and the NTN gateway 30 sends the uplink signal to the core network device 50. Taking downlink transmission as an example, a downlink signal from the core network device 50 is sent to the NTN gateway 30, and the NTN gateway 30 forwards the downlink signal to the satellite 20, and then the satellite 20 forwards the downlink signal to the terminal device 10.

In the network architecture shown in fig. 1 and 2 described above, the access network device 40 is a device for providing wireless communication services to the terminal device 10. A connection may be established between the access network device 40 and the terminal device 10 so that communication, including interaction of signaling and data, may take place over the connection. The number of access network devices 40 may be plural, and communication between two adjacent access network devices 40 may be performed by wired or wireless means. The terminal device 10 may switch between different access network devices 40, i.e. establish a connection with different access network devices 40.

Taking a cellular communication network as an example, the access network device 40 in the cellular communication network may be a base station. A base station is a device deployed in an access network to provide wireless communication functionality for a terminal device 10. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of base station capable devices may vary, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "base station" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal device 10 with a wireless communication function are collectively referred to as a base station or an access network device.

In addition, the terminal device 10 according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), mobile Station (MS), terminal devices (terminal devices), and so on. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a terminal device. In the embodiments of the present application, some places use "UE" to represent "terminal device". In the embodiments of the present application, the "network device" may be an access network device (e.g., a base station) or a satellite.

In addition, taking a 5G NTN network as an example, a plurality of satellites 20 may be included in the NTN network. One satellite 20 may cover a range of ground areas and provide wireless communication services to the terminal devices 10 on that ground area. In addition, the satellites 20 may orbit the earth, and by deploying multiple satellites 20, communication coverage of different areas of the earth's surface may be achieved.

In addition, in the embodiments of the present application, the terms "network" and "system" are commonly used in combination, but those skilled in the art will understand the meaning. The technical solution described in the embodiments of the present application may be applied to an LTE (Long Term Evolution ) system, a 5G NR system, a subsequent evolution system of the 5G NR system, or other communication systems, which is not limited in this application.

Before the technical scheme of the application is described, some background knowledge related to the application is described.

1. Timing Advance value (TA)

An important feature of uplink transmission is that different terminal devices are orthogonally multiple-access in time-frequency, i.e. uplink transmissions from different terminal devices of the same serving cell do not interfere with each other. In order to guarantee orthogonality of the uplink transmission, avoiding intra-cell (intra-cell) interference, the network device requires that signals from different terminal devices of the same time but different frequency domain resources arrive at the network device substantially aligned. To guarantee time synchronization at the network device side, the NR supports a mechanism of uplink timing advance.

The network device can control the time at which the uplink signals from the different terminal devices arrive at the network device by appropriately controlling the offset of each terminal device. For a terminal device farther from the network device, uplink data is sent in advance than a terminal device closer to the network device due to a larger transmission delay.

The network device determines the TA for each terminal device based on measuring the uplink transmissions of the terminal devices.

2. Timing advance group (Timing Advance Group, TAG)

In the carrier aggregation (Carrier Aggregation, CA) scenario, the terminal device uses different TAs for different uplink carriers, so the concept of TAG is introduced in the standard. The network configures a maximum of 4 TAGs for each group of cells (cell group) of the terminal device, and simultaneously configures its associated TAG for each cell from which the terminal device selects which cell corresponds to the TA in the TAGs, one for each TAG.

3. Offset value Koffset

In the NR system, after the terminal device receives the uplink grant in the network device scheduling information in the downlink time slot n, uplink data is transmitted in the uplink time slot n+K, where K is an uplink resource time slot offset supported in the uplink grant, and is used to determine a time domain resource position of uplink transmission. Since the transmission delay is significantly increased in the NTN network, the uplink timing advance of the terminal device is significantly increased, so that the value range of K in the NR system cannot meet the normal timing sequence of uplink and downlink transmission, and therefore an offset value Koffset is introduced to solve the problem.

For example, the transmission timing of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) scheduled by the downlink control information (Downlink Control Information, DCI) is as shown in fig. 3: if the terminal equipment receives the scheduling DCI on the downlink time slot n, the time slot allocated for PUSCH transmission is an uplink time slot Since Koffset is introduced, it is guaranteed that the terminal device can transmit PUSCH at a time point after receiving the scheduling DCI. Here, the effect of Koffset is that if Koffset is not present, it is as in NR systemAfter the TA mechanism, the time slot of the terminal for carrying out the PUSCH transmission is obviously wrong in time sequence before the DCI is received. Here, K ₂ Indicated in the scheduling DCI, mu _PUSCH Sum mu _PDCCH For determining the subcarrier spacing configured for PUSCH and PDCCH, respectively. K (K) ₂ The value of (2) is in the range of 0 to 32.

As another example, the transmission timing of PUSCH scheduled by random access response (Random Access Response, RAR) grant (grant): for a time slot scheduled by the RAR grant for PUSCH transmission, the terminal equipment performs transmission in the time slot n+K ₂ +Δ+K _offset And transmitting the PUSCH. Wherein K is ₂ The value of (a) is indicated by an uplink grant in the RAR, and delta is defined by the protocol.

For another example, hybrid automatic repeat request (Hybrid Automa) is transmitted on PUCCH tic Repeat reQuest, HARQ) -Acknowledgement (ACK) transmission timing: for the time slot of PUCCH transmission, the terminal device should be in time slot n+k ₁ + _offset Corresponding HARQ-ACK information is transmitted on the physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources within. Wherein K is ₁ Is the number of slots and is indicated by the PDSCH-to-HARQ-timing-indicator information field in the DCI format or is provided by the dl-DataToUL-ACK parameter. K (K) ₁ The last slot of the PUCCH transmission corresponding to=0 overlaps with the PDSCH reception or the slot received by the physical downlink control channel (Physical Downlink Control Channel, PDCCH) indicating the release of the Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) PDSCH.

As another example, the medium access control layer control unit (Media Access Control Element, MAC CE) activates timing: when the HARQ-ACK information corresponding to the PDSCH including the MAC CE command is transmitted on the slot n, the corresponding behavior indicated by the MAC CE command and the assumed downlink configuration of the terminal device should be from the slotThe first time slot after that starts to take effect, where X may be determined by the terminal device capabilities of the NTN. Wherein,the number of slots included in each subframe in the subcarrier spacing configuration μ is represented.

For another example, channel state information (Channel State Information, CSI) refers to resource timing: for the CSI reference resource reporting the CSI in the uplink time slot n ', the CSI reference resource reporting the CSI in the uplink time slot n' is based on a single downlink time slotAnd (3) determining. Wherein,μ _DL sum mu _UL The downlink and uplink sub-carriers are arranged at intervals. n is n _{CSI_ref} The value of (2) depends on the type of CSI reporting.

For another example, aperiodic SRS transmission timing: if the terminal equipment receives DCI trigger transmission aperiodic SRS in downlink time slot n, the terminal equipment transmits the aperiodic SRS in uplink time slotAnd up-transmitting the aperiodic SRS in each triggered SRS resource set. Wherein k is configured by a higher layer parameter (slotOffset) in each triggered SRS resource set and is determined according to a subcarrier spacing corresponding to the triggered SRS transmission, μ _SRS Sum mu _PDCCH The configuration of the subcarrier spacing of the triggered SRS transmission and the PDCCH carrying the trigger command, respectively.

4. Koffset configuration

Currently, the network mainly refers to TA to configure Koffset values. For example, k offset is configured according to the maximum TA supported in the cell or in one satellite beam, or dedicated Koffset is configured for the terminal device with reference to the TA of the terminal device.

In NTN CA scenarios, for example, where GEO and LEO use CA for networking, there may be a large difference in TA used by a terminal device for different serving cells, and if only one Koffset is configured for one terminal device and the Koffset is applied to all serving cells, unnecessary uplink scheduling delay may be caused for those serving cells with smaller actual TA.

Referring to fig. 4, a flowchart of a timing parameter configuration method provided in an embodiment of the present application is shown, where the method may be performed by a terminal device, and the method may include the following steps:

step 410, receiving timing parameter configuration information sent by a network device, where the timing parameter configuration information is used to determine a time domain resource of uplink transmission of a terminal device.

The timing parameter configuration information is used for indicating Koffset used by the terminal equipment in the service cell, so that an offset value Koffset used by the terminal equipment in different service cells is matched with a timing advance value TA used by the terminal equipment in different service cells.

Illustratively, the timing parameter configuration information is used to indicate Koffset of the terminal device in one serving cell; alternatively, the timing parameter configuration information is used to indicate Koffset of the terminal device in a plurality of serving cells, i.e., to indicate Koffset of the terminal device in a different serving cell.

Here, the terminal device corresponds to a plurality of serving cells, but the network may configure Koffset for only a part of the plurality of serving cells, or may configure Koffset for all of the plurality of serving cells.

Koffset here is a time offset, and the unit may be set to various time units in the time domain, such as a slot, or the like, as needed.

In the solution provided in the present application, the network configures Koffset for a serving cell means that at least one of a common Koffset and a terminal-specific (specific) Koffset is configured for the serving cell, and the network does not configure Koffset for a serving cell means that neither the common Koffset nor the terminal-specific Koffset is configured.

In general, when the network configures Koffset for all serving cells, the common Koffset for all serving cells is an optional configuration. Accordingly, when the network configures Koffset for only a portion of the serving cells, then the common Koffset for the serving cells is an optional configuration.

The timing parameter configuration information is used to indicate at least one of: public Koffset of the serving cell of the terminal device, terminal-specific Koffset of the terminal device on at least one serving cell.

Illustratively, the timing parameter configuration information is for indicating a common Koffset of at least one of the plurality of serving cells of the terminal device. That is, the timing parameter configuration information is used to indicate the common Koffset of one of the plurality of serving cells of the terminal device, or the timing parameter configuration information is used to indicate the common Koffset of the plurality of serving cells of the terminal device.

Likewise, the timing parameter configuration information is used to indicate the terminal-specific Koffset of the terminal device in one serving cell, or the timing parameter configuration information is used to indicate the terminal-specific Koffset of the terminal device in each of the plurality of serving cells.

Wherein the common Koffset configured by the network to the serving cell means Koffset commonly configured by the network to all terminal apparatuses having the cell as the serving cell. The network may configure a common Koffset for each serving cell.

The terminal-specific Koffset is the Koffset allocated to a specific terminal device by the network for one serving cell. The network may assign different terminal-specific koffsets to different terminal devices for the same serving cell.

When determining the Koffset of the service cell, the terminal equipment firstly determines whether the network configures the terminal exclusive Koffset for the service cell for the terminal equipment, if so, the terminal exclusive Koffset for the service cell, which is configured for the terminal equipment by the network, is adopted, and if not, the public Koffset, which is configured for the service cell by the network, is adopted.

In an exemplary embodiment, there may be one or more common Koffset for each serving cell.

When the common Koffset is one, the common Koffset is a cell-level common Koffset;

when the common Koffset is plural, the common Koffset is a common Koffset of satellite beam levels within the serving cell.

The satellite beam refers to a shape formed on the earth surface by electromagnetic waves emitted from a satellite antenna of a satellite. One satellite corresponds to at least one satellite beam, different satellite beams correspond to different coverage, adjacent satellite beams may have partially overlapping coverage, and one satellite beam corresponds to at least one synchronization signal block (Synchronization Signal Block, SSB).

In the CA scenario, the network may configure multiple TAGs for the terminal device, different TAGs may use different TAs, and one service cell corresponds to one TAG, so in the NTN network, the terminal-specific Koffset may be configured corresponding to either the TAG or the service cell.

For example, the terminal-specific Koffset is a terminal-specific Koffset of a TAG of the terminal device, one TAG being associated with each serving cell;

alternatively, the terminal-specific Koffset is a terminal-specific Koffset of a serving cell of the terminal device.

In the embodiment of the present application, the timing parameter configuration information indicates the terminal-specific Koffset of the TAG of the terminal device in the following manner:

First, the indication mode corresponding to TAG

The timing parameter configuration information comprises 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 of all TAGs of the terminal device, in which case Koffset and TAG are one-to-one, and for another example, the timing parameter configuration information includes a terminal-specific Koffset configured for each of partial TAGs of the terminal device, and terminal-specific Koffset is not configured for another partial TAG of the terminal device, and serving cells corresponding to TAGs for which no terminal-specific Koffset is configured use a common Koffset.

Alternatively, the timing parameter configuration information comprises a Koffset list comprising a plurality of koffsets, each of the at least one TAG of the terminal device being associated with one of the Koffset lists; likewise, all TAGs of the terminal can be assigned a terminal-specific Koffset by way of a Koffset list, or only a part of the TAGs can be assigned a terminal-specific Koffset.

Here, there are two ways of associating Koffset list and TAG:

1. implicit association mode

The timing parameter configuration information includes only the Koffset list. The plurality of koffsets in the Koffset list are arranged in the same order as the corresponding TAGs.

Illustratively, a TAG list is configured in the terminal, and the length of the TAG list and the length of the Koffset list form a one-to-one correspondence, and the TAG in the TAG list and the Koffset in the Koffset list correspond to the ith Koffset in the Koffset list, and i is a positive integer and does not exceed the length of the TAG list.

2. Explicit association mode

The timing parameter configuration information includes, in addition to the Koffset list, the association relationship of Koffset and TAG in the Koffset list.

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

In the explicit correlation, the number of Koffset and TAG may be equal or unequal.

For example, the number of koffsets is less than the number of TAGs. When all TAGs of the terminal are configured with a terminal-specific Koffset, there is a case where one Koffset corresponds to more than one TAG, i.e., in this case, koffset and TAG exist in one-to-many relationship.

Second, the indication mode of the corresponding service cell

The timing parameter configuration information includes Koffset corresponding to each of at least one serving cell of the terminal device; for example, the timing parameter configuration information includes a terminal-specific Koffset configured for each of all the serving cells of the terminal device, in which case Koffset and serving cell are one-to-one, and for another example, the timing parameter configuration information includes a terminal-specific Koffset configured for each of the partial serving cells of the terminal device, and a terminal-specific Koffset not configured for another partial serving cell of the terminal device, which use a common Koffset.

Alternatively, the timing parameter configuration information includes a Koffset list including a plurality of koffsets, each of at least one serving cell of the terminal device being associated with one of the Koffset lists; likewise, a terminal-specific Koffset may be allocated to all the cells of the terminal device by means of a Koffset list, or only to a part of the cells.

Similarly, the Koffset list and the serving cell also have both implicit and explicit association methods, and specific schemes refer to association parts of the Koffset list and the TAG, which are not described herein.

According to the timing parameter configuration method, the terminal equipment determines the Koffset used by each service cell based on the parameter configuration information, the offset value Koffset used by the terminal equipment in different service cells is matched with the timing advance value TA used by the terminal equipment in different service cells, uplink scheduling delay caused by the fact that all the service cells use the same Koffset is avoided, and network communication quality is improved.

Referring to fig. 5, a flowchart of a timing parameter configuration method provided in an embodiment of the present application is shown, where the method may be performed by a network device, and the method may include the following steps:

Step 510, sending timing parameter configuration information to the terminal device, where the timing parameter configuration information is used to determine a time domain resource of uplink transmission of the terminal device.

The timing parameter configuration information is used for indicating Koffset used by the terminal equipment in the service cell, so that offset value Koffset used by the terminal equipment in different service cells is matched with timing advance value TA used by the terminal equipment in different service cells.

The specific configuration manner of the parameter configuration information is referred to in step 410.

Referring to fig. 6, a flowchart of a timing parameter configuration method provided in an embodiment of the present application is shown, where the method may be performed by a terminal device and a network device together, and the method may include the following steps:

in step 610, the network device generates timing parameter configuration information, where the timing parameter configuration information is used to determine a time domain resource of uplink transmission of the terminal device.

The timing parameter configuration information is used for indicating an offset value Koffset used by the terminal equipment in different service cells, so that the offset value Koffset used by the terminal equipment in different service cells is matched with a timing advance value TA used by the terminal equipment in different service cells.

In an exemplary embodiment, the network device determines the common Koffset and the terminal-specific Koffset of the individual serving cells of the terminal device from the TA of the individual serving cells.

In determining Koffset, it is necessary to ensure that Koffset is not less than the TA of the corresponding serving cell. For example, the public Koffset of a serving cell is not smaller than the corresponding maximum TA in the coverage of the serving cell, and the terminal dedicated Koffset of the terminal equipment on a serving cell is not smaller than the TA of the terminal on the serving cell.

For example, the common Koffset of a serving cell is equal to the corresponding maximum TA within the coverage of the serving cell, and the terminal-specific Koffset of the terminal device on a serving cell is equal to the TA of the terminal on the serving cell.

In step 620, the network device sends timing parameter configuration information to the terminal device. The terminal equipment receives timing parameter configuration information sent by the network equipment.

As described above, the timing parameter configuration information includes two parts, common Koffset and terminal-specific Koffset, and the common Koffset and the terminal-specific Koffset may be separately transmitted when the network device transmits the parameter configuration information to the terminal device.

In an exemplary embodiment, the common Koffset is sent as follows:

for a main serving cell of a terminal device, the network device transmits a public Koffset for the serving cell to the terminal device through broadcasting; the terminal device receives a common Koffset for the serving cell transmitted by the network device through broadcasting.

For the secondary serving cell of the terminal device, the network device sends a common Koffset for the serving cell to the terminal device through broadcast or dedicated radio resource control (Radio Resource Control, RRC) signaling; the terminal device receives a common Koffset for the serving cell transmitted by the network device through broadcasting or unicast.

Wherein, the broadcasting may be implemented by a system information block (System Information Block, SIB), a master system information block (Master Information Block, MIB), etc., and the unicast may be implemented by dedicated RRC signaling, MAC CE signaling, PDCCH signaling, etc.

The Primary serving Cell is a Primary Cell (pcell), and the Secondary serving Cell is a Secondary Cell (Scell).

Of course, the scheme provided in the application is also applicable to a primary cell group (Master Cell group, MCG) and a secondary cell group (Secondary Cell group, SCG) in a dual link (DC, dual connectivity) scenario, where the primary serving cell may be a primary secondary cell (Primary Secondary Cell, PScell).

In an exemplary embodiment, the terminal-specific Koffset is sent as follows:

the network equipment sends a terminal exclusive Koffset aiming at a service cell to the terminal equipment through UE exclusive signaling; the terminal equipment receives the terminal exclusive Koffset aiming at the service cell and sent by the network equipment through the UE exclusive signaling.

The UE-specific signaling is, for example, dedicated RRC signaling, MAC CE signaling, or PDCCH signaling.

In step 630, the terminal device determines the Koffset used by the terminal device on each serving cell according to the timing parameter configuration information.

In an exemplary embodiment, the terminal device determines the Koffset used on each serving cell as follows:

if the terminal exclusive Koffset is configured for the first service cell in the timing parameter configuration information, determining the terminal exclusive Koffset corresponding to the first service cell as the Koffset used by the terminal equipment in the first service cell, wherein the first service cell is any service cell;

And if the terminal exclusive Koffset is not configured for the first service cell in the timing parameter configuration information, determining the public Koffset configured for the first service cell in the timing parameter configuration information as the Koffset used by the terminal equipment in the first service cell.

In an exemplary embodiment, the terminal device determines the common Koffset of the first serving cell as follows:

if the common Koffset of the cell level is configured for the first service cell in the timing parameter configuration information, determining the common Koffset of the cell level configured for the first service cell as the Koffset used by the terminal equipment in the first service cell;

if the common Koffset of the satellite beam level is configured for the first serving cell in the timing parameter configuration information, determining the common Koffset of the satellite beam level corresponding to the satellite beam where the terminal equipment is located in the satellite beam corresponding to the first serving cell as the Koffset used by the terminal equipment in the first serving cell.

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

If the public Koffset is not configured for the first service cell in the timing parameter configuration information, determining the dedicated Koffset or the public Koffset of the terminal configured for the main service cell of the terminal equipment as the Koffset used by the terminal equipment in the first service cell;

or if the public Koffset is not configured for the first serving cell in the timing parameter configuration information, determining the largest terminal exclusive Koffset or the largest public Koffset configured for all the second serving cells associated with the TAG corresponding to the first serving cell as the Koffset used by the terminal equipment in the first serving cell. The second serving cell is a serving cell other than the first serving cell in the serving cells associated with the TAG.

Here, determining the terminal-specific Koffset or the common Koffset configured for the primary serving cell of the terminal device as the Koffset used by the terminal device in the first serving cell may include the following cases:

first, the common Koffset configured for the primary serving cell of the terminal device is directly determined as the Koffset used by the terminal device in the first serving cell.

Secondly, when the terminal exclusive Koffset is configured for the main service cell of the terminal equipment, determining the terminal exclusive Koffset configured for the main service cell of the terminal equipment as the Koffset used by the terminal equipment in the first service cell; if no terminal-specific Koffset is allocated to the primary serving cell of the terminal, the common Koffset allocated to the primary serving cell of the terminal is determined as the Koffset used by the terminal in the first serving cell.

Here, the maximum terminal-specific Koffset or the maximum common Koffset configured for all the second serving cells associated with the TAG corresponding to the first serving cell refers to the maximum terminal-specific Koffset among the terminal-specific koffsets configured for all the second serving cells associated with the TAG corresponding to the first serving cell, or the maximum common Koffset among the common koffsets configured for all the second serving cells associated with the TAG corresponding to the first serving cell.

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

The terminal device determines, based on the timing parameter configuration information, that the serving cell associated to TAG1 uses terminal-specific Koffset1, that the serving cell associated to TAG2 uses terminal-specific Koffset1, and that the serving cell associated to TAG3 uses terminal-specific Koffset2.

In the third embodiment, the timing parameter configuration information configures a cell-level common Koffset for each serving cell of the terminal device, configures a terminal-specific Koffset1 for a serving cell1 of the terminal device, configures a terminal-specific Koffset2 for a serving cell2 of the terminal device, and does not configure a terminal-specific Koffset for a serving cell 3 of the terminal device.

The terminal device determines, based on the timing parameter configuration information, that the serving cell1 uses the terminal-specific Koffset1, that the serving cell2 uses the terminal-specific Koffset2, and that the serving cell 3 uses the common Koffset of the serving cell 3.

Fourth, the timing parameter configuration information configures a cell-level common Koffset for each serving cell of the terminal device, configures a serving cell list for one serving cell group of the terminal device, including Pcell1, scell1, and Scell2, configures a Koffset list for one serving cell group of the terminal device, including terminal-specific Koffset1 and terminal-specific Koffset2, and indicates that Pcell1 and Scell1 are associated with terminal-specific Koffset1, and Scell2 is associated with terminal-specific Koffset2.

The terminal device determines that Pcell1 uses terminal-specific Koffset1, scell2 uses terminal-specific Koffset2 based on the timing parameter configuration information.
