That is to say, the satellites may be LEO satellites, MEO satellites, GEO satellites, or HEO satellites, etc. according to different orbital altitudes.

Wherein, the signal transmitted by the satellite in the embodiment of the present application usually generates one or more beams (beam, or called beam) on a given service area (given service area) bounded by its field of view (field of view) footprint). At the same time, the shape of a beam on the ground can be elliptical, and the field of view of the satellite depends on the antenna and the minimum elevation angle.

First, some nouns and technical solutions involved in the embodiments of the present application are explained to facilitate the understanding of those skilled in the art.

1. NTN communication system

In the NTN communication system, satellites usually generate one or more beams (beams, or called beam footprints) or cells on the ground, and the shape of a beam on the ground can be elliptical. Among them, the beams or cells generated by some satellites (such as LEO satellites) on the ground will also move on the ground as the satellite moves in its orbit; or, some satellites (such as LEO satellites or GEO satellites) on the ground The resulting beam or cell does not move on the ground as the satellite moves in its orbit. As shown in FIG. 3, the beam generated by a satellite (such as a LEO satellite or a GEO satellite) on the ground does not move on the ground as the satellite moves in its orbit.

Since the distance between the satellite and the ground is very far (for example, GEO satellite is 35786km), within the coverage of the same beam or cell, the difference in the propagation distance between the terminal equipment (such as UE) and the satellite in different geographical locations is small (That is, the path loss difference of signals corresponding to terminal devices in different geographical locations within the coverage of the same beam/cell is small), which in turn leads to the signal reception quality corresponding to terminal devices in different geographical locations within the coverage of the same beam/cell (including the downlink receiving quality of the terminal equipment or the uplink receiving quality of the base station) the difference is very small, as shown in FIG. 4 .

In the land network communication system shown in (a) of FIG. 4 , there are

terminal devices

4201 and 4202 with different geographic locations within the coverage of the same beam/cell. Since there is a large difference between the propagation distance from the network device 410 to the terminal device 4201 and the propagation distance to 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. difference. However, in the NTN communication system shown in (b) of FIG. 4 , there are terminal equipment 4401 and terminal equipment 4402 with different geographic locations within the coverage of the same beam/cell. Since the distance from the satellite 430 to the ground is very far, there is a small difference between the propagation distance from the satellite 430 to the terminal device 4401 and the propagation distance to the terminal device 4402, resulting in the signal reception quality corresponding to the terminal device 4401 corresponding to that of the terminal device 4402 There is a small difference between the signal reception quality of the two.

2. Architecture of NTN communication system

The architecture of the NTN communication system in the embodiment of the present application mainly includes an NTN communication architecture (that is, transparent forwarding mode) with a transparent satellite (transparent satellite) (or called bent pipe payload (bent pipe payload)) and a regenerative satellite (regenerative satellite) ) NTN communication architecture (that is, regenerative signal mode), please refer to FIG. 5 . Among them, (a) of FIG. 5 exemplifies the NTN communication architecture with transparent satellites, and FIG. 5 (b) exemplifies the NTN communication architecture with regenerative satellites. In (a) of FIG. 5 , the satellite 510 in the transparent forwarding mode generates at least one beam 520 on the ground, and the at least one beam 520 can form a cell on the ground. At this time, the terminal device 530 located in the cell can measure one of all the beams in the cell, and establish a communication connection with the satellite 510 through the beam. Similarly, in (b) of FIG. 5 , the satellite 540 in the regenerative signal mode generates at least one beam 550 on the ground, and the at least one beam 550 can form a cell on the ground. At this time, the terminal device 560 located in the cell can measure one of all the beams in the cell, and establish a communication connection with the satellite 540 through the beam.

3. The maximum differential delay value in the NTN communication system

In the NTN communication system, since the satellite is relatively far from the ground, and the coverage of the beam or cell formed by the satellite is relatively large, there is a large differential time delay within the coverage of the beam or cell, such as the maximum differential time delay of the synchronous satellite. 2 times the delay value is 20.6ms.

The maximum differential delay value corresponding to the coverage area of a cell or beam refers to the difference between the propagation delay corresponding to the position farthest from the satellite and the propagation delay corresponding to the position closest to the satellite within the coverage area of a certain cell or beam. difference between.

For example, taking the coverage of the beam as an example, as shown in FIG. 6 , D1 represents the shortest distance from the satellite 610 to the coverage area 620 of the beam, and D2 represents the furthest distance from the satellite 610 to the coverage area 620 of the beam. Therefore, the maximum differential delay value corresponding to the coverage area 620 of the beam is 2*D3/c; where, c represents the speed of light; the symbol "/" represents the division sign, that is, the division operation is performed; the symbol "*" represents the multiplication sign , that is, perform the multiplication operation. Thus, 2*D3/c means 2 times D3/c, or 2 times D3/c.

4. Timing advance (TA) in land network communication system

TA, used for uplink transmission of the terminal device, means that the terminal device needs to send an uplink subframe a certain time earlier than receiving a downlink subframe. Since the TAs corresponding to (or used/adopted) by different terminal devices are different, different terminal devices can send uplink data in advance of the TA, so that the uplink data of different terminal devices arrive at the network device at the same time Basically aligned, which is beneficial for network devices to receive uplink data correctly.

TA can be calculated by the network device according to the random access preamble (RA preamble) sent by the terminal device, and then sent to the terminal through the timing advance command (timing advance command, TAC) field in the MAC random access response (RAR) The device, that is, the network device configures the TA to the terminal device.

5. TA in NTN communication system

In the NTN communication system, since the satellite will continue to move along a fixed orbit, the propagation delay (or propagation distance) between the terminal device and the satellite and the distance between the satellite and the network device (or non-ground network gateway) Propagation delay (or propagation distance) changes rapidly with the constant motion of the satellite.

In order to solve the problem of constantly changing propagation delay, the terminal device needs to obtain full TA (full TA) before sending uplink data. Among them, the full TA is equal to the sum of the terminal equipment specific timing advance (UE-specific TA) and the common timing advance (common TA).

The UE-specific TA can be calculated by the terminal device through its own location information (such as calculated by the global navigation satellite system) and satellite ephemeris (satellite ephemeris).

The common TA may be the round trip time (RTT) between the reference point and the network device. The common TA may be calculated by the terminal device according to the common timing advance rate indicated (or configured) by the network device, or may be directly instructed (or configured) by the network device to the terminal device.

For example, as shown in FIG. 7, d0 represents the distance from the satellite 730 to the reference point 720; d1 represents the distance d1 from the terminal device 710 to the satellite 730; d0_F represents the distance from the non-terrestrial network gateway 740 to the satellite 730. Wherein, d1 is calculated by the terminal device 710 according to its own location information and satellite ephemeris. Therefore, UE-specific TA is defined as follows:

TA_1=2*(d1-d0)/c, c is expressed as the speed of light;

The common TA is defined as follows:

TA_2=2*(d0+d0_F)/c;

fullTA is defined as follows:

TA=TA_1+TA_2.

It should be noted that the symbol "*" appearing in this application represents a multiplication sign, that is, a multiplication operation is performed. For example, 2*(d1-d0) means 2 times (d1-d0), or 2 times (d1-d0), etc.

6. K_offset in NTN communication system

In the NTN communication system, when the terminal device sends uplink data, it will send the uplink data in advance according to the timing. Compared with the terrestrial network communication system, due to the larger propagation delay in the NTN communication system, the TA corresponding to the terminal device when sending uplink data will also be larger. Based on this, the existing protocol needs to enhance (enhancements) for TA, and the enhancement can be to introduce an offset (K_offset), and apply K_offset to modify the relevant transmission timing relationship in the NTN communication system. Wherein, K_offset can also be an additional time interval.

For example, in the existing PDCCH scheduling PUSCH process, the DCI in the PDCCH will indicate a scheduling delay value (protocol called K2) to the terminal equipment, and the terminal equipment can determine the transmission resource position of the PUSCH according to the indicated K2 value. However, in the NTN communication system, if the terminal device sends uplink data in advance according to the TA value, it means that there must be a sufficiently large time interval between the PDCCH receiving moment and the PUSCH sending resource location (at least not less than the TA value ) to ensure the early transmission of the terminal equipment. Therefore, in the NTN communication system, the scheduling delay of PDCCH scheduling PUSCH is enhanced to: K2+K_offset, which can ensure that there is a large enough time interval between the receiving time of PDCCH and the sending time of PUSCH for terminal equipment to send in advance, as shown in Figure 8 shown.

In addition, K_offset can be configured to the terminal device through system information or RRC dedicated signaling.

7. Preconfigured resource transmission

Since a terminal device in an idle state or an inactive state needs to enter a connected state through a random access process before sending data, the data transmission mechanism in an idle or inactive state will increase RRC signaling overhead, Terminal equipment energy consumption and transmission delay and other issues, so in order to ensure that the terminal equipment can send data in the idle state, you can configure periodic pre-configured resources for the terminal equipment in advance.

Preconfigured resource transmission may include periodic preconfigured uplink resource (preconfigure uplink resource, PUR) transmission and periodic preconfigured downlink resource (preconfigure downlink resource, PUR) transmission.

In the RRC connection state, pre-configured uplink resource transmission is also called configured grant uplink transmission, which has two types: configured grant type 1 (configured grant type 1) and configured grant type 2 (configured grant type 2).

For configured grant type 1, once the terminal device receives the high-level configuration of configured grant type 1, the terminal device can determine the time-frequency position of the pre-configured uplink resource according to the high-level configuration, and use the pre-configured uplink resource to send uplink data.

For configured grant type 2, after receiving the high-level configuration of configured grant type 2, the terminal device needs to receive the downlink control information (DCI) issued by the network device, and determine whether the configured grant type 2 configured by the high-level is available according to the DCI.

8. Measurement gap (measurement gap, GAP)

The measurement is divided into intra-frequency measurement and inter-frequency measurement.

Same-frequency measurement means that the serving cell where the terminal device is currently located and the target cell to be measured are on the same carrier frequency point (central frequency point).

Inter-frequency measurement means that the serving cell where the terminal device is currently located and the target cell are not on the same carrier frequency point.

If the terminal equipment needs to perform inter-frequency measurement, a simple way is to install two types of RF receivers in the terminal equipment to measure the frequency points of the serving cell and the frequency points of the target cell respectively, but this will bring about cost increase and different frequency The problem of mutual interference between points. Therefore, the 3rd generation partnership project (3rd generation partnership project, 3GPP) proposes a measurement gap method, that is, to reserve a period of time (that is, the length of the measurement gap). During this period of time, the terminal equipment will not send or receive any data, but tune the RF receiver to the frequency point of the target cell for signal quality measurement, and then tune the RF receiver back to the serving cell after the period of time is over To continue normal sending and receiving work.

The network device can configure periodic measurement gaps to the terminal device through configuration information. Wherein, the configuration information may be used to configure the start position of the measurement gap, the length of the measurement gap, and the period of the measurement gap, etc., and the configuration information may include the measGapConfig information element of the MeasConfig field of the high-layer parameter RRCConnectionReconfiguration.

Since the terminal device cannot transmit and receive data during the measurement gap, when the time domain position of the uplink resource overlaps with the measurement gap in the time domain, the terminal device will not be able to use the uplink resource for uplink data transmission.

In addition, after the TA mechanism is introduced, for terminal devices in the land network communication system, since the TA corresponding to the terminal device when using uplink resources to send uplink data is very small, the uplink resources are ahead of the time domain after the TA The location may be equivalent to the time domain location of the uplink resource.

For the network equipment in the land network communication system, since the measurement gap, uplink resource and TA are all configured to the terminal equipment by the network equipment, the network equipment can judge whether the time domain position of the uplink resource ahead of the TA is consistent with The measurement gap overlaps in the time domain, so that there is no need to blindly detect uplink resources overlapping with the measurement gap, so as to save energy consumption.

However, compared with the above-mentioned land network communication system, due to the larger propagation delay in the NTN communication system, the standard protocol introduces K_offset to modify the relevant transmission timing relationship in the NTN communication system.

In addition, for a terminal device in the NTN communication system, since the TA corresponding to the terminal device when using the uplink resource to send uplink data is very large, the time domain position of the uplink resource ahead of the TA cannot be equivalent to the uplink resource. The temporal location of the resource.

For the network equipment in the NTN communication system, if the terminal equipment does not report the TA for uplink transmission, the network equipment does not know the TA when the terminal equipment transmits uplink. In addition, even if the terminal device reports the TA, the TA reported by the terminal device will be quite different from the TA actually used by the terminal device for uplink transmission due to the continuous movement and changes of the satellite. Therefore, the network device cannot determine whether the time domain position of the uplink resource ahead of TA will overlap with the measurement gap in the time domain when the terminal device uses the uplink resource for data transmission, that is, the network device cannot determine which uplink resources the terminal device cannot It is used for uplink data transmission, which causes network devices to perform blind detection on each uplink resource, resulting in unnecessary energy consumption.

In addition, in the NTN communication system, part of the TA for uplink transmission by the terminal device is independently calculated by the terminal device, and part of it is indicated by the network device. When the terminal device does not report the TA, the network device does not know the TA sent by the terminal uplink. In addition, even if the terminal device reports the TA sent uplink, due to the fast movement of the satellite, the actual TA of the terminal device will be quite different from the previously reported TA. For uplink resource transmission, because the network device does not know the TA actually sent by the terminal, the network device cannot determine whether the terminal device will overlap with the measurement gap when using the uplink resource for data transmission. How to solve the overlapping problem of uplink resource transmission and measurement gap in the NTN scenario needs further research.

To sum up, in the NTN communication system, the embodiment of the present application aims at how the adjusted relationship between the time domain position of the uplink resource and the measurement gap will affect the transmission of data by the terminal device and the monitoring of the uplink resource by the network device, The specific research is as follows:

1. For terminal equipment

If it is determined that the time domain position of the uplink resource ahead of the TA overlaps with the time domain position of the measurement gap, the terminal device does not use the uplink resource to send data; or,

If it is determined that the time domain position of the uplink resource ahead of the TA does not overlap with the time domain position of the measurement gap, the terminal device uses the uplink resource to send data; or,

If it is determined that there is a measurement gap overlapping with the time domain position of the uplink resource ahead of TA, the terminal device does not use the uplink resource to send data; or,

If it is determined that there is no measurement gap overlapping with the time domain position of the uplink resource ahead of TA, the terminal device uses the uplink resource to send data; or,

If it is determined (or determined/judged) that the uplink resource overlaps with the measurement gap after the TA is advanced in the time domain, the terminal device does not use the uplink resource to send data; or,

If it is determined (or determined/judged) that the uplink resource does not overlap with the measurement gap after the TA is advanced in the time domain, the terminal device uses the uplink resource to send data; or,

etc.

2. For network equipment

If it is determined (or determined/judged) that the time domain position of the uplink resource ahead of the TA overlaps with the time domain position of the measurement gap, the network device does not blindly detect the uplink resource; or,

If it is determined (or determined/judged) that the time domain position of the uplink resource ahead of the TA does not overlap with the time domain position of the measurement gap, the network device blindly detects the uplink resource; or,

If it is determined (or determined/judged) that there is a measurement gap overlapping with the time domain position of the uplink resource ahead of the TA, the network device does not blindly detect the uplink resource; or,

If it is determined (or determined/judged) that there is no measurement gap overlapping with the time domain position of the uplink resource ahead of the TA, the network device blindly detects the uplink resource; or,

If it is determined (or determined/judged) that the uplink resource overlaps with the measurement gap after the TA is advanced in the time domain, the network device does not blindly detect the uplink resource; or,

If it is determined (or determined/judged) that the uplink resource does not overlap with the measurement gap after the TA is advanced in the time domain, the network device blindly detects the uplink resource; or,

etc.

It should be noted that the TA advanced by the uplink resource may be an enhanced TA in the NTN communication system, such as a full TA.

In addition, the measurement gap may be a measurement time slot before the uplink resource. It can be understood that since the measurement gap can be configured periodically, when judging whether the time domain position after the uplink resource is advanced by TA overlaps with the time domain position of the measurement gap, the measurement time slot is located in the time domain A certain measurement time slot before the uplink resource.

It should be noted that the start time domain position of the measurement gap can also be located after the start time domain position of the uplink resource ahead of TA, but the start time domain position of the measurement gap is located after the end time domain position of the uplink resource ahead of TA Previously, it is sufficient as long as the time-domain position of the measurement gap overlaps with the time-domain position of the uplink resource after the TA advance.

It can be seen that, for the terminal device, the embodiment of the present application introduces an uplink resource availability (or validity) criterion, that is, whether the time domain position of the uplink resource ahead of TA overlaps with the time domain position of the measurement gap, so that the terminal device According to the criterion, it can determine which uplink resources it can use for data transmission, so as to ensure the success of data transmission and improve the robustness of the NTN communication system.

Similarly, for network devices, the embodiment of the present application introduces an uplink resource monitoring (or availability/validity) judgment criterion, that is, whether the time domain position of the uplink resource ahead of TA overlaps with the time domain position of the measurement gap, The network device can determine which uplink resources cannot be used by the terminal device for data transmission according to the criterion. Therefore, the network device does not need to perform blind detection on these uplink resources, thereby helping to save energy consumption of the network device.

In order to realize the above-mentioned technical solutions, other contents, concepts and meanings that may be involved will be further explained below.

1. Configure uplink resources and measurement gaps

It should be noted that the terminal device may receive various configuration information issued by the network device during cell search, cell access, cell camping, random access, uplink and downlink resource scheduling, and other processes. Wherein, the various configuration information includes resource configuration information for configuring uplink resources (such as time-frequency domain resource position, period, time-frequency domain resource size, etc. for configuring uplink resources) and resource configuration information for configuring measurement gaps (such as Configure the time domain resource location, period, time length, etc. of the measurement gap).

In addition, in some embodiments, the uplink resource may be a pre-configured uplink resource. For details, refer to the content in "7. Pre-configured resource transmission" above, which will not be repeated here.

2. The TA advanced by the uplink resources in the time domain

Combining with the content in the above "TA in the NTN communication system", the TA advanced by the uplink resource in the time domain may be a full TA. Therefore, the terminal device needs UE-specific TA calculated by its own location information and satellite ephemeris, and the network device needs to configure (or indicate) common timing advance rate or common TA to the terminal device.

3. Overlap

It should be noted that, the time-frequency domain resource position at which the network device configures the uplink resource to the terminal device may include a start time domain position and an end time domain position. Similarly, the network device configures the time domain resource position of the measurement gap to the terminal device may include a start time domain position and an end time domain position.

In this embodiment of the present application, the start time domain position of the uplink resource may be the start time unit of the uplink resource, and the end position of the uplink resource may be the end time unit of the uplink resource. Wherein, the time unit can be understood as the granularity of communication between the terminal device and the network device in the time domain, that is, the terminal device and the network device communicate in the time domain using the time unit as the granularity/unit. For example, the time unit may be subframe, time slot, symbol, mini-slot, etc., which is not limited. Take the time unit as a time slot as an example. The start position of the uplink resource is the start time slot of the uplink resource, and the end time domain position of the uplink resource may be the end time slot of the uplink resource. Similarly, when the time unit is a symbol, the start position of the uplink resource is the start symbol of the uplink resource, and the end time domain position of the uplink resource may be the end symbol of the uplink resource.

Similarly, the start time domain position of the measurement gap may be the start time unit of the measurement gap; the end time domain position of the measurement gap may be the end time unit of the measurement gap. Take the time unit as a time slot as an example. The start position of the measurement gap is the start time slot of the uplink resource, and the end time domain position of the measurement gap may be the end time slot of the uplink resource.

Therefore, for overlap, it can be understood as follows:

1) The time domain position of the uplink resource advanced by TA and the time domain position of the measurement gap partially or completely overlap in time domain; or, the uplink resource completely or partially overlaps with the measurement gap after being advanced by TA in time domain.

2) The start time domain position (or end time domain position) after the uplink resource advances TA is within the measurement gap;

3) The time interval between the start time domain position of the uplink resource ahead of TA and the start time domain position of the measurement gap is less than the duration of the measurement interval; or, the end time domain position of the uplink resource ahead of TA is within the measurement interval .

4) The time interval between the end time domain position after the uplink resource advances TA and the time domain position of the measurement gap is less than the duration of the measurement interval.

For example, as shown in Figure 9. In (a) of FIG. 9 , the uplink resource 910 is advanced by TA, so that the uplink resource 910 is located in the time domain position 920 after the advance of TA, that is, the uplink resource 910 is located in the measurement gap 930 after the advance of TA, that is, the uplink resource 910 is located in the measurement gap 930 after the advance of TA. It completely overlaps with the part of the measurement gap 930, and L is the duration of the measurement gap. In (b) of FIG. 9 , the uplink resource 910 is advanced by TA to obtain a time domain position 920 , and the time domain position 920 partially overlaps with the measurement gap.

4. Not using the uplink resource to send data and using the uplink resource to send data

For not using the uplink resource to send data, it can be understood as follows:

1) Not using (or not using) uplink resources to send data;

2) Not using (or not using) uplink resources to send data to network devices;

3) Not using (or not using) uplink resources for data transmission;

4) Do not transmit data at the time domain position of the uplink resource ahead of TA;

5) Not using (or not using) the uplink resource to transmit data after advancing TA in time domain.

Similarly, descriptions similar to those described above for sending data using the uplink resources will not be repeated here.

It should be noted that the uplink resources are not used or used to send data, and the data here can be understood as uplink data, that is, data sent from a terminal device to a network device.

5. Do not blindly check the uplink resource and blindly check the uplink resource

For not blindly checking the uplink resource, it can be understood as follows:

1) Do not perform blind detection on the uplink resource;

2) Do not perform blind detection on the uplink resource.

Similarly, the blind detection of the uplink resource can be understood as follows:

1) performing blind detection on the uplink resource;

2) Perform blind detection on the uplink resource.

6. How to determine whether the time domain position of the uplink resource ahead of TA overlaps with the time domain position of the measurement gap or whether there is a measurement gap overlapping with the time domain position of the uplink resource ahead of TA

It should be noted that the embodiment of the present application can be judged in the following manner:

1) According to K_offset, it is determined that the time domain position of the uplink resource ahead of the TA overlaps (or does not overlap) with the time domain position of the measurement gap. For details, refer to the relevant description in the following method 1;

2) According to K_offset, it is determined that there is (or does not exist) a measurement gap that overlaps with the time domain position after the uplink resource advances TA, for details, refer to the relevant description in the following method 2;

3) According to the TA, it is determined that the time domain position of the uplink resource ahead of the TA overlaps (or does not overlap) with the time domain position of the measurement gap, for details, refer to the relevant description in the following method 3;

4) According to the TA, it is determined that there is (or does not exist) a measurement gap overlapping with the time domain position of the uplink resource ahead of the TA. For details, refer to the relevant description in the fourth method below.

Of course, in this embodiment of the present application, the parameters used to determine whether the uplink resource overlaps with the measurement gap in the time domain after TA is advanced, or determine whether there is a measurement gap that overlaps with the uplink resource in the time domain after TA is advanced Or information is not limited, and there is no limitation on whether the parameters or information used by the terminal device and the network device to determine overlap are the same, and whether the determination method is the same, as long as the terminal device and the network device have the same determination results.

The above manner will be described in detail below.

method one:

Combining the above "6. K_offset in the NTN communication system", it can be seen that K_offset can be an additional time interval (or delay value/offset), which can be an additional scheduling delay configured by the network device to the terminal device value. The unit of the K_offset can be millisecond, time slot or subframe. K_offset can be configured to the terminal device through system information or RRC dedicated signaling.

In addition, in the embodiment of the present application, the K_offset can be regarded as a maximum value of TA, that is, when the terminal device uses uplink resources to transmit data, the corresponding TA will not exceed the K_offset.

At the same time, in order to determine (or determine/judgment) according to the K_offset whether the time domain position of the uplink resource advanced by TA overlaps with the time domain position of the measurement gap, the embodiment of the present application may also introduce M, L, T0, T1, Toffset, etc. .

1) The concept of M

M may be the time interval between the uplink resource and the measurement gap.

It should be noted that the measurement gap may be a measurement slot before the uplink resource in the time domain.

Combining with the content in the above "overlap", it can be seen that the time-frequency domain resource positions of the uplink resources may include the start time domain position and the end time domain position, and the time domain resource positions of the measurement gap may include the start time domain position and the end time domain position . In this regard, M can have the following conditions:

①M is the time interval between the start time domain position (or end time domain position) of the uplink resource and the start time domain position of the measurement gap;

②M is the time interval between the start time domain position (or end time domain position) of the uplink resource and the end time domain position of the measurement gap.

2) The concept of L

L may be the duration of the measurement gap, that is, the length of the measurement gap in the time domain.

Combining with the content in the above "1. Configuring uplink resources and measurement gaps", it can be seen that the L may be configured by the network device to the terminal device. In addition, the L may also be predefined or preconfigured by the protocol, which is not specifically limited.

The unit of L may be milliseconds.

3) The concept of T0

T0 may be a preconfigured duration. For example, the T0 may be configured for the terminal device by the network, may be predefined or preconfigured by the protocol, and there is no specific limitation on this.

The unit of T0 may be millisecond, time slot or subframe.

In some embodiments, T0 may be the difference between the maximum and minimum values of TA.

In addition, T0 may be a cell-level configuration, a beam-level configuration, or a terminal device-level configuration.

① T0 is the configuration at the cell level

When T0 is configured at the cell level (that is, the T0 value at the cell level), the network device may determine the T0 according to the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device. Then, the network device can configure the T0 to the terminal device.

For example, the network device sends first indication information to the terminal device, where the first indication information may be used to indicate the T0. Correspondingly, the terminal device receives the first indication information sent by the network device. Wherein, the first indication information may be carried by system information or RRC signaling.

In addition, the maximum differential delay value corresponding to the coverage of the serving cell can be understood in conjunction with the above "3. The maximum differential delay value in the NTN communication system", and will not be repeated here.

In some embodiments, how to determine the T0 according to the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device can be determined according to the following formula:

T0≥2T;

Wherein, 2T represents twice of T, and T is the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device. That is to say, T0 is not less than twice the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device.

②T0 is beam-level configuration

Similarly, when T0 is configured at the beam level (that is, the T0 value at the beam level), the network device can determine the T0 according to the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device. Then, the network device can configure the T0 to the terminal device.

In addition, the maximum differential delay value corresponding to the coverage of the current serving beam can be understood in conjunction with the above-mentioned "3. The maximum differential delay value in the NTN communication system", which will not be repeated here.

In some embodiments, how to determine the T0 according to the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device can be determined according to the following formula:

T0≥2T;

Wherein, 2T represents twice of T, and T is the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device. That is to say, T0 is not less than twice the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device.

③Configuration at the terminal device level

When T0 is configured at the terminal equipment level (that is, the T0 value at the UE level), the network device can determine the T0 according to the TA reported by the terminal equipment, and can determine it according to the location information reported by the terminal equipment.

It should be noted that when a terminal device reports a TA, the TA can be a full TA or a UE-specific TA. Since the network device has a common TA, the network device can calculate the full TA based on the UE-specific TA and common TA reported by the terminal device.

When the location information reported by the terminal device, the network device can calculate the UE-specific TA based on the location information and the satellite ephemeris, and then calculate the full TA.

In addition, although the current full TA obtained by the network device (reported by the terminal device or calculated by the network device based on the UE-specific TA reported by the terminal device) will change due to the continuous movement of the satellite, the satellite follows the predetermined Orbits with a known speed of movement and altitude of the orbit. Based on this, the network device can determine a fixed variable duration according to the current full TA (for example, querying a mapping table with the current full TA), and the fixed variable duration is T0.

4) The concept of T1

T1 may be a preconfigured duration. For example, the T0 may be configured for the terminal device by the network, may be predefined or preconfigured by the protocol, and there is no specific limitation on this.

For example, the network device sends third indication information to the terminal device, where the third indication information may be used to indicate the T1. Correspondingly, the terminal device receives the third indication information sent by the network device. Wherein, the third indication information may be carried by system information or RRC signaling.

The unit of T1 may be millisecond, time slot or subframe.

In some embodiments, T1 can be determined according to the following formula:

T1=T0+L.

Combining the contents of "2) Concept of L" and "3) Concept of T0", it can be seen that T1 may be configured at the cell level, at the beam level, or at the terminal device level. The same reason can be seen as follows:

①T1 is cell-level configuration

When T1 is configured at the cell level (that is, the T1 value at the cell level), the network device can determine the T1 according to the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device and the duration of the measurement gap. Then, the network device can configure the T1 to the terminal device.

In some embodiments, how to determine T1 according to the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device and the duration of the measurement gap can be determined according to the following formula:

T1≥2T+L;

Wherein, 2T represents twice of T, and T is the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device. That is to say, T1 is not less than the sum of twice the maximum differential delay value corresponding to the coverage of the serving cell of the terminal device and the duration of the measurement gap.

②T1 is beam-level configuration

Similarly, when T1 is configured at the beam level (that is, the T1 value at the beam level), the network device can determine the T1 according to the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device and the duration of the measurement gap. Then, the network device can configure the T1 to the terminal device.

In some embodiments, how to determine T1 according to the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device and the duration of the measurement gap can be determined according to the following formula:

T0≥2T+L;

Wherein, 2T represents twice of T, and T is the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device. That is to say, T1 is not less than the sum of twice the maximum differential delay value corresponding to the coverage of the current serving beam of the terminal device and the duration of the measurement gap.

③Configuration at the terminal device level

When T1 is configured at the terminal device level (that is, the T1 value at the UE level), the network device can determine the T1 according to the TA reported by the terminal device and the duration of the measurement gap, or according to the location information reported by the terminal device and the duration of the measurement gap Determining the T1 is specifically consistent with the description in "3) The concept of T0" above, and details will not be repeated here.

5) The concept of Toffset

Toffset may be a preconfigured time offset (or duration/delay value). For example, the Toffset may be configured for the terminal device by the network, may be predefined or preconfigured by the protocol, and there is no specific limitation on this.

The unit of Toffset can be millisecond, time slot or subframe.

It should be noted that Toffset is similar to T0 configured at the terminal device level. Although the current full TA obtained by the network device (reported by the terminal device or calculated by the network device based on the UE-specific TA reported by the terminal device) will change due to the continuous movement of the satellite, the satellite runs along a predetermined orbit , with known velocity and orbital altitude. Based on this, the network device can determine a fixed change duration according to the current full TA (for example, obtain by querying a mapping table with the current full TA), and the fixed change duration is Toffset.

That is to say, Toffset can be determined by the network device according to the satellite moving speed or the satellite orbit height, can be determined according to the TA or position information reported by the terminal device, can be determined according to the TA, satellite moving speed, and satellite orbit height reported by the terminal device The determined one may be determined according to the position information reported by the terminal device, the moving speed of the satellite, and the altitude of the satellite orbit. There is no specific limitation on this.

To sum up, in "Method 1", the terminal device or network device can make a judgment based on K_offset and M, it can make a judgment based on K_offset, M, T0 and L, it can judge whether it overlaps according to K_offset, M and T1, etc. wait. A detailed description will be given below.

6) According to K_offset and M, it is judged whether the time domain position of the uplink resource after TA advances overlaps with the time domain position of the measurement gap. Among them, the size relationship between K_offset and M may exist as follows:

①M≤K_offset

It should be noted that, for an uplink resource, if M≤K_offset exists, it means that the time interval between the uplink resource and the measurement gap is less than or equal to K_offset, where M is the time interval between the uplink resource and the measurement gap. Since K_offset is regarded as a maximum value of TA, the TA corresponding to the terminal device using the uplink resource to transmit data may be greater than M, which may cause the time domain position of the uplink resource to be ahead of the time domain position after TA and the time domain position of the measurement gap Overlap, so that the terminal device does not use the uplink resource to send data, and the network device does not blindly detect the uplink resource.

For example, taking M as the time interval between the start time domain position of the uplink resource and the end time domain position of the measurement gap, as shown in FIG. 10 , when M≤K_offset, it means that TA may be greater than M. Therefore, the uplink resource 1010 is advanced by the TA, so that the uplink resource 1010 is located in the time domain position 1020 after the TA is advanced, that is, the uplink resource 1010 is located in the measurement gap 1030 after the TA is advanced, that is, the uplink resource 1010 is positioned in the measurement gap 1030 after the TA is advanced. 1030 overlap.

②M＞K_offset

Similarly, for an uplink resource, if there is M>K_offset, that is, there is no M≤K_offset, it means that the time interval between the uplink resource and the measurement gap is greater than K_offset, where M is the distance between the uplink resource and the measurement gap time interval. Since K_offset is regarded as a maximum value of TA, the corresponding TA of the terminal equipment when using the uplink resource to transmit data will be smaller than M, resulting in that the time domain position of the uplink resource ahead of TA is different from the time domain position of the measurement gap overlap, so that the terminal device can use the uplink resource to send data, and the network device can blindly detect the uplink resource.

7) According to K_offset, M, T0 and L, determine whether the time domain position of the uplink resource ahead of TA overlaps with the time domain position of the measurement gap

It should be noted that, in the embodiment of the present application, the judgment may be made according to the magnitude relationship among K_offset, M, T0 and L. Among them, the size relationship between K_offset, M, T0 and L may exist as follows:

①K_offset-T0-L≤M≤K_offset

It should be noted that for an uplink resource, if K_offset-T0-L≤M≤K_offset exists, it means that the time interval between the uplink resource and the measurement gap is less than or equal to K_offset, and the time interval between the uplink resource and the measurement gap The time interval is greater than or equal to the difference between K_offset, T0 and L, where M is the time interval between the uplink resource and the measurement gap. At this time, in the embodiment of the present application, K_offset may be regarded as a maximum value of TA, and K_offset-T0 may be regarded as a minimum value of TA. Therefore, the TA corresponding to the terminal device using the uplink resource to transmit data may be greater than M, which may cause the time domain position of the uplink resource ahead of TA to overlap with the time domain position of the measurement gap, so that the terminal device does not use the uplink resource. The resource sends data, and the network device does not blindly detect the uplink resource.

For example, as shown in FIG. 11 , M is the time interval between the start time domain position of the uplink resource 1110 and the end time domain position of the measurement gap. When M=K_offset, the end time domain position of the measurement gap is at position 1130 . At this time, if M≦K_offset, the measurement gap will move to the uplink resource 1120, causing the uplink resource 1120 to overlap with the measurement gap.

When M=K_offset-T0-L, the start time-domain position of the measurement gap is at position 1140 . At this time, if K_offset-T0-L≤M, the measurement gap will move to the uplink resource 1120, causing the uplink resource 1120 to overlap with the measurement gap.

②M<K_offset-T0-L

Similarly, for an uplink resource, if there is M<K_offset-T0-L, that is, there is no K_offset-T0-L≤M≤K_offset, it means that the time interval between the uplink resource and the measurement gap is less than K_offset-T0-L , where M is the time interval between the uplink resource and the measurement gap. K_offset-T0 is regarded as a minimum value of TA. Although the TA corresponding to the terminal device may be greater than M when using the uplink resource to transmit data, it may still cause the time domain position of the uplink resource to be ahead of the TA and the gap between the measurement gap. The positions in the time domain do not overlap, so that the terminal device can use the uplink resource to send data, and the network device can blindly detect the uplink resource.

③M>K_offset

Similarly, for an uplink resource, if there is M>K_offset, that is, there is no K_offset-T0-L≤M≤K_offset, it means that the time interval between the uplink resource and the measurement gap is greater than K_offset, where M is the uplink resource and the time interval between measurement gaps. Since K_offset is regarded as a maximum value of TA, the corresponding TA of the terminal equipment when using the uplink resource to transmit data will be smaller than M, resulting in that the time domain position of the uplink resource ahead of TA is different from the time domain position of the measurement gap overlap, so that the terminal device can use the uplink resource to send data, and the network device can blindly detect the uplink resource.

8) According to K_offset, M and T1, determine whether the time domain position of the uplink resource ahead of TA overlaps with the time domain position of the measurement gap

It should be noted that, in the embodiment of the present application, the judgment may be made according to the magnitude relationship among K_offset, M, and T1. Among them, the size relationship between K_offset, M and T1 may exist as follows

①K_offset-T1≤M≤K_offset

It should be noted that for an uplink resource, if K_offset-T1≤M≤K_offset exists, it means that the time interval between the uplink resource and the measurement gap is less than or equal to K_offset, and the time interval between the uplink resource and the measurement gap greater than or equal to the difference between K_offset and T1, where M is the time interval between the uplink resource and the measurement gap. At this time, in the embodiment of the present application, K_offset may be regarded as a maximum value of TA, and K_offset-T1+L may be regarded as a minimum value of TA. Therefore, the TA corresponding to the terminal device using the uplink resource to transmit data may be greater than M, which may cause the time domain position of the uplink resource advanced by TA to overlap with the time domain position of the measurement gap, so that the terminal device does not use the uplink resource. The data is sent, and the network device does not blindly detect the uplink resource.

②M<K_offset-T1

Similarly, for an uplink resource, if there is M<K_offset-T1, that is, there is no K_offset-T1≤M≤K_offset, it means that the time interval between the uplink resource and the measurement gap is less than K_offset-T1, where M is the Time interval between uplink resource and measurement gap.

3) According to K_offset, M and T1, determine whether there is a measurement gap overlapping with the time domain position of the uplink resource ahead of TA

It should be noted that, in the embodiment of the present application, the judgment may be made according to the magnitude relationship among K_offset, M, and T1. Among them, the size relationship between K_offset, M and T1 may exist as follows:

①K_offset-T1≤M≤K_offset

A detailed description will be given below. 1) According to TA, M, Toffset and L, it is determined whether the time domain position of the uplink resource ahead of TA overlaps with the time domain position of the measurement gap

It should be noted that, in the embodiment of the present application, the determination may be made according to the magnitude relationship among TA, M, Toffset, and L. Among them, the size relationship between TA, M, Toffset and L may exist as follows:

①TA-Toffset-L≤M≤TA+Toffset

It should be noted that, for an uplink resource, if TA-Toffset-L≤M≤TA+Toffset exists, it means that the time interval between the uplink resource and the measurement gap is less than or equal to TA+Toffset, and the uplink resource and the measurement gap The time interval between is greater than or equal to the difference between TA, Toffset and L, where M is the time interval between the uplink resource and the measurement gap. At this time, in the embodiment of the present application, TA+Toffset may be regarded as a maximum value of TA, and TA-Toffset may be regarded as a minimum value of TA. Therefore, the TA corresponding to the terminal device using the uplink resource to transmit data may be greater than M, which may cause the time domain position of the uplink resource ahead of TA to overlap with the time domain position of the measurement gap, so that the terminal device does not use the uplink resource. The resource sends data, and the network device does not blindly detect the uplink resource.

For example, as shown in FIG. 12 , the terminal device reports TA or location information to the network device, and the network device determines Toffset according to the TA or location information, and sends Toffset to the terminal device. Wherein, M is the time interval between the start time domain position of the uplink resource 1210 and the end time domain position of the measurement gap. The end time domain position of the measurement gap is at position 1230 when M=TA+Toffset. At this time, if M≦TA+Toffse, the measurement gap will move to the uplink resource 1220, causing the uplink resource 1220 to overlap with the measurement gap.

When M=TA-Toffset-L, the start time-domain position of the measurement gap is at position 1240 . At this time, if TA-Toffset-L≦M, the measurement gap will move to the uplink resource 1220, causing the uplink resource 1220 to overlap with the measurement gap.

②M<TA-Toffset-L

Similarly, for an uplink resource, if there is M<TA-Toffset-L, that is, there is no TA-Toffset-L≤M≤TA+Toffset, it means that the time interval between the uplink resource and the measurement gap is less than TA-Toffset -L, where M is the time interval between the uplink resource and the measurement gap. TA-Toffset is regarded as a minimum value of TA. Although the TA corresponding to the terminal device may be greater than M when using the uplink resource to transmit data, it may still cause the time domain position of the uplink resource to be ahead of the TA and the gap between the measurement gap. The positions in the time domain do not overlap, so that the terminal device can use the uplink resource to send data, and the network device can blindly detect the uplink resource.

③M>TA+Toffset

Similarly, for an uplink resource, if there is M>TA+Toffset, that is, there is no TA-Toffset-L≤M≤TA+Toffset, it means that the time interval between the uplink resource and the measurement gap is greater than TA+Toffset, where , M is the time interval between the uplink resource and the measurement gap. Since TA+Toffset is regarded as a maximum value of TA, the TA corresponding to the terminal device when using the uplink resource to transmit data will be smaller than M, thus causing the uplink resource to be ahead of the time domain position after TA and the time domain of the measurement gap The locations do not overlap, so that the terminal device can use the uplink resource to send data, and the network device can blindly detect the uplink resource.

Method 4: It should be noted that in "Method 4", in order to determine (or determine/judge) whether there is a measurement gap that overlaps with the time domain position of the uplink resource ahead of the TA according to the TA, the embodiment of the present application may also Introduce M, L, Toffset, etc. Wherein, the specific descriptions of M, L, and Toffset are consistent with those in the above "method 1", and will not be repeated here.

1) According to TA, M, Toffset and L, determine whether there is a measurement gap overlapping with the time domain position of the uplink resource ahead of TA

①TA-Toffset-L≤M≤TA+Toffset

It should be noted that, for an uplink resource, if there is TA-Toffset-L≤M≤TA+Toffset, it means that there may be a measurement gap overlapping with the time domain position of the uplink resource ahead of TA, so that the terminal device does not use The uplink resource sends data, and the network device does not blindly detect the uplink resource.

②M<TA-Toffset-L

Similarly, for an uplink resource, if there is M<TA-Toffset-L, that is, there is no TA-Toffset-L≤M≤TA+Toffset, it means that there may be no overlap with the time domain position of the uplink resource ahead of TA measurement gap, so that the terminal device can use the uplink resource to send data, and the network device can blindly detect the uplink resource.

③M>TA+Toffset

Similarly, for an uplink resource, if there is M>TA+Toffset, that is, there is no TA-Toffset-L≤M≤TA+Toffset, it means that there may be no measurement overlapping with the time domain position of the uplink resource ahead of TA gap, so that the terminal device can use the uplink resource to send data, and the network device can blindly detect the uplink resource.

It should be noted that the implementation manners of "mode 4" and "mode 3" are specifically the same. Therefore, you can refer to "Method 3" for details that are not exhaustive in "Method 4", and will not repeat them here.
