That is, the satellites may be LEO satellites, MEO satellites, GEO satellites, HEO satellites, or the like according to the orbit heights.

Among other things, the signals transmitted by satellites in embodiments of the present application will typically produce one or more beams (or "beam footprint") on a given service area (given service area) bounded by its field of view. Meanwhile, the shape of one beam on the ground may be elliptical, and the field of view of the satellite depends on the antenna and the minimum elevation angle, etc.

In addition, the AAU realizes partial physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer may eventually become information of the PHY layer or be converted from the information of the PHY layer, higher layer signaling (e.g., RRC layer signaling) may be considered to be transmitted by the DU or by the du+aau. It is understood that the network device may include devices of one or more of CU nodes, DU nodes, AAU nodes. In addition, the CU may be divided into network devices in an access network (radio access network, RAN), or may be divided into network devices in a Core Network (CN), which is not particularly limited.

It should be noted that the satellite payload implements frequency conversion and radio frequency amplifiers in both the uplink and downlink directions, the satellite corresponding to an analog RF repeater. Furthermore, different transparent satellites may be connected to the same gNB on the ground.

First, some terms and technical solutions involved in the embodiments of the present application are explained so as to be easily understood by those skilled in the art.

1. NTN communication system

In NTN communication systems, satellites typically generate one or more beams (or "beam antennas") or cells on the ground, while one beam may be elliptical in shape on the ground. Wherein a beam or cell generated by a portion of the satellites (e.g., LEO satellites) on the ground will also move on the ground as the satellites move in their orbits; alternatively, a beam or cell generated by a portion of the satellites (e.g., LEO satellites or GEO satellites) on the ground does not move on the ground as the satellite moves in its orbit. As shown in fig. 3, a beam generated by a satellite (e.g., LEO satellite or 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, the GEO satellite is 35786 km), the difference of propagation distances between the terminal devices (such as UEs) at different geographic locations and the satellite in the coverage area of the same beam or cell is small (i.e., the difference of path loss of signals corresponding to the terminal devices at different geographic locations in the coverage area of the same beam/cell is small), which in turn results in very small difference of signal receiving quality (including downlink receiving quality of the terminal device or uplink receiving quality of the base station) corresponding to the terminal devices at different geographic locations in the coverage area of the same beam/cell, as shown in fig. 4.

In the land network communication system shown in fig. 4 (a),

terminal devices

4201 and 4202 having different geographical locations within the coverage area of the same beam/cell. Since there is a large difference between the propagation distance of the network device 410 to the terminal device 4201 and the propagation distance to the terminal device 4202, there is caused 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. Whereas in the NTN communication system shown in fig. 4 (b),

terminal devices

4401 and 4402 having different geographical locations within the coverage area 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 a small difference between the signal reception quality corresponding to the terminal device 4401 and the signal reception quality corresponding to the terminal device 4402.

2. Architecture of NTN communication system

The architecture of the NTN communication system in the embodiments of the present application mainly includes an NTN communication architecture (i.e., transparent forwarding mode) with transparent satellites (transparent satellite) (or called bent-tube payloads (bent pipe payload)) and an NTN communication architecture (i.e., regenerated signal mode) with regenerated satellites (regenerative satellite), please refer to fig. 5. Where (a) of fig. 5 illustrates an NTN communication architecture with transparent satellites, and (b) of fig. 5 illustrates an NTN communication architecture with regenerative satellites. In fig. 5 (a), the transparent repeating mode satellite 510 generates at least one beam 520 on the ground, and the at least one beam 520 may form a cell on the ground. At this time, the terminal device 530 located in the cell may measure one beam among all beams of the cell and establish a communication connection with the satellite 510 through the beam. Similarly, in fig. 5 (b), the satellite 540 reproducing the signal pattern generates at least one beam 550 on the ground, and the at least one beam 550 may form a cell on the ground. At this time, the terminal device 560 located in the cell may measure one beam among all beams of the cell and establish a communication connection with the satellite 540 through the beam.

3. Maximum differential delay value in NTN communication system

In NTN communication systems, since satellites are relatively far from the ground and the coverage area of a beam or cell formed by the satellites is relatively large, there is a large differential delay in the coverage area of the beam or cell, for example, the maximum differential delay value of a geostationary satellite is 20.6ms, which is 2 times.

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

For example, taking the coverage of a beam as an example, as shown in fig. 6, D1 is represented as the closest distance of the satellite 610 to the coverage area 620 of the beam, and D2 is represented as the furthest distance of the satellite 610 to the coverage area 620 of the beam. Therefore, the coverage area 620 of the beam corresponds to a maximum differential delay value of 2×d3/c; wherein c is represented as the speed of light; the symbol "/" indicates a divisor, i.e. performs a division operation; the symbol "×" is denoted as the multiplication, i.e. a multiplication operation is performed. Thus, 2 x D3/c represents 2 times D3/c, or 2 times D3/c.

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

The TA, used for uplink transmission of the terminal device, means that the terminal device needs to send an uplink subframe in advance of receiving a downlink subframe by a certain time. Since the TAs corresponding to (or used/employed by) the different terminal devices are different, the different terminal devices may each transmit upstream data in advance of the TAs, so that the upstream data of the different terminal devices are substantially aligned in time of arrival at the network device, thereby facilitating correct reception of the upstream data by the network device.

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

5. TA in NTN communication system

In NTN communication systems, since a satellite moves along a fixed orbit, the propagation delay (or propagation distance) between a terminal device and the satellite and the propagation delay (or propagation distance) between the satellite and a network device (or non-terrestrial network gateway) can change rapidly with the continuous movement of the satellite.

In order to solve the problem that propagation delay is continuously changed, before uplink data is sent, a terminal device needs to acquire a full TA (full TA). Wherein the full TA is equal to the sum of a terminal device specific timing advance (UE-specific TA) and a common timing advance (common TA).

The UE-specific TA may be calculated by the terminal device from its own location information (e.g., calculated by the global navigation satellite system) and satellite ephemeris (satellite ephemeris).

The common TA may be a Round Trip Time (RTT) between the reference point and the network device. The common TA may be calculated by the terminal device according to a common time advance change rate (common timing advance rate) indicated (or configured) by the network device, or may be directly indicated (or configured) by the network device to the terminal device.

For example, as shown in FIG. 7, d0 is represented as the distance of satellite 730 from reference point 720; d1 is denoted as the distance d1 of the terminal device 710 from the satellite 730; d0_f is represented as the distance of non-terrestrial network gateway 740 to satellite 730. Wherein d1 is calculated by the terminal device 710 based on its own position information and satellite ephemeris. Thus, the UE-specific TA is defined as follows:

ta_1=2, (d 1-d 0)/c, c being denoted as the speed of light;

common TA is defined as follows:

TA_2＝2*(d0+d0_F)/c；

full TA is defined as follows:

TA＝TA_1+TA_2。

note that the symbol "×" appearing in the present application indicates a multiplication, i.e., a multiplication operation is performed. For example, 2 x (d 1-d 0) refers to 2 times (d 1-d 0), or 2 times (d 1-d 0), etc.

6. K_offset in NTN communication system

In the NTN communication system, when transmitting uplink data, a terminal device performs timing advance transmission according to TA. Compared with a land network communication system, because there is a 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, existing protocols require enhancements (enhancements) for the TA, which may be introducing an offset (k_offset) and applying k_offset to modify the relevant transmission timing relationship in the NTN communication system. The k_offset may be an additional time interval.

For example, in the existing PUSCH scheduling process of the PDCCH, the DCI in the PDCCH may indicate a scheduled delay value (called K2) of the terminal device, and the terminal device may determine the transmission resource location of the PUSCH according to the indicated K2 value. However, in the NTN communication system, if the terminal device performs advanced transmission according to the TA value when transmitting uplink data, it means that there must be a sufficiently large time interval (at least not smaller than the TA value) between the PDCCH receiving time and the PUSCH transmission resource location to ensure advanced transmission of the terminal device. Therefore, in the NTN communication system, the scheduling delay of PDCCH scheduling PUSCH is enhanced as: k2+k_offset, so that a sufficiently large time interval between the PDCCH receiving time and the PUSCH transmitting time can be ensured for the terminal device to transmit in advance, as shown in fig. 8.

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

7. Preconfigured resource transmission

Since the terminal device in idle state or inactive state (inactive) can send data only after entering the connection state through the random access process, and the data transmission mechanism in idle or inactive state can increase the problems of RRC signaling overhead, terminal device energy consumption, transmission delay and the like, in order to ensure that the terminal device can send data in idle state, periodic pre-configuration resources can be configured for the terminal device in advance.

The pre-configured resource transmissions may include periodic pre-configured uplink resource (preconfigure uplink resource, PUR) transmissions and periodic pre-configured downlink resource (preconfigure downlink resource, PUR) transmissions.

In the RRC connected state, preconfigured uplink resource transmissions, also called configured grant (configured grant) uplink transmissions, exist in two types: configuration authorization type 1 (configured grant type 1) and configuration authorization type2 (configured grant type 2).

For configured grant type, once the terminal device receives the higher layer configuration of configured grant type 1, the terminal device may determine the time-frequency location of the preconfigured uplink resource according to the higher layer configuration, and use the preconfigured uplink resource to transmit uplink data.

For configured grant type, after receiving the higher layer configuration of configured grant type2, the terminal device needs to receive Downlink Control Information (DCI) issued by the network device, and determine whether configured grant type2 of the higher layer configuration is available according to the DCI.

8. Measurement GAP (measurement GAP)

The measurements are divided into on-channel measurements (intra-frequency measurement) and off-channel measurements (inter-frequency measurement).

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

The inter-frequency measurement means that the serving cell and the target cell where the terminal equipment is currently located are not located on one carrier frequency point.

If the terminal equipment needs to perform different frequency measurement, a simple way is to install 2 radio frequency receivers in the terminal equipment to respectively measure the frequency point of the serving cell and the frequency point of the target cell, but this brings the problems of cost improvement and mutual interference between different frequency points. Therefore, the third generation partnership project organization (3rd generation partnership project,3GPP) proposes a measurement gap approach, i.e. reserving a period of time (i.e. the length of the measurement gap). And in the period of time, the terminal equipment does not send and receive any data, but adjusts the radio frequency receiver to the frequency point of the target cell to measure the signal quality, and adjusts the radio frequency receiver back to the service cell after the period of time is finished so as to continue normal transceiving operation.

The network device may configure the periodic measurement gap to the terminal device via the configuration information. The configuration information may be used to configure a start position of the measurement gap, a length of the measurement gap, a period of the measurement gap, and the like, and the configuration information may include measGapConfig cells of a MeasConfig field of the higher layer parameter rrcconnectionreconfigurations.

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 cannot utilize the uplink resource to transmit uplink data.

In addition, after introducing the TA mechanism, for the terminal device in the land network communication system, since the TA corresponding to the terminal device when transmitting the uplink data by using the uplink resource is very small, the time domain position of the uplink resource after advancing the TA can be equivalent to the time domain position of the uplink resource.

For network equipment in a land network communication system, because the measurement gap, the uplink resource and the TA are configured to the terminal equipment by the network equipment, the network equipment can judge whether the time domain position of the uplink resource after advancing the TA overlaps with the measurement gap in the time domain, so that blind detection of the uplink resource overlapping with the measurement gap is not needed, and energy consumption is saved.

However, compared to the land network communication system described above, since there is a greater 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 a TA corresponding to the terminal device when transmitting uplink data by using an uplink resource is very large, a time domain position after the uplink resource advances by the TA cannot be equivalent to a time domain position of the uplink resource.

For a network device in the NTN communication system, if the terminal device does not report the TA of the uplink transmission, the network device does not know the TA when the terminal device transmits the uplink. In addition, even if the terminal device reports the TA, the TA reported by the terminal device and the TA actually adopted by the uplink transmission of the terminal device have larger difference due to the continuous motion change of the satellite. Therefore, the network device cannot determine whether the time domain position of the terminal device after the uplink resource advances by TA when the uplink resource is used for data transmission overlaps with the measurement gap in the time domain, that is, the network device cannot determine which uplink resources are unavailable for uplink data transmission by the terminal device, so that the network device needs to perform blind detection on each uplink resource, and unnecessary energy consumption is generated.

In addition, in the NTN communication system, a part of the TA that the terminal device performs uplink transmission is autonomously calculated by the terminal device, and the other part is indicated by the network device. Under the condition that the terminal equipment does not report the TA, the network equipment does not know the TA which is sent by the terminal in the uplink. In addition, even if the terminal device reports the uplink TA, there is a large difference between the actual TA of the terminal device and the previously reported TA due to the rapid movement of the satellite. For uplink resource transmission, the network device does not know the TA actually sent by the terminal in uplink, so that the network device cannot determine whether the terminal device overlaps with the measurement gap when sending data by using the uplink resource. How to solve the overlapping problem of uplink resource transmission and measurement gap in NTN scenario, further research is needed.

In summary, in the NTN communication system, the specific research of how the relation between the adjusted time domain position of the uplink resource and the measurement gap affects the transmission of data by the terminal device and the monitoring of the uplink resource by the network device is as follows:

1. for terminal equipment

If the time domain position of the uplink resource after TA is advanced is overlapped with the time domain position of the measurement gap, the terminal equipment does not use the uplink resource to send data; or,

If the time domain position of the uplink resource after TA is advanced is judged to be not overlapped with the time domain position of the measurement gap, the terminal equipment transmits data by utilizing the uplink resource; or,

if the measurement gap overlapped with the time domain position after the advance TA of the uplink resource exists, the terminal equipment does not use the uplink resource to send data; or,

if the fact that the measurement gap overlapped with the time domain position after the advance TA of the uplink resource does not exist is judged, the terminal equipment sends data by utilizing the uplink resource; or,

if the uplink resource is determined (or determined/judged) to be overlapped with the measurement gap after TA is advanced in the time domain, the terminal equipment does not use the uplink resource to send data; or,

if the uplink resource is determined (or determined/judged) to be not overlapped with the measurement gap after TA is advanced in the time domain, the terminal equipment transmits data by using the uplink resource; or,

etc.

2. For network devices

If the time domain position of the uplink resource after TA is advanced is overlapped with the time domain position of the measurement gap, the network equipment does not blindly detect the uplink resource; or,

if the time domain position of the uplink resource after TA is advanced is judged (or determined/judged) and the time domain position of the measurement gap is not overlapped, the network equipment 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 after the upstream resource advances by TA, the network device does not blindly detect the upstream resource; or,

if it is determined (or determined/judged) that there is no measurement gap overlapping with the time domain position after the upstream resource advances by TA, the network device blindly detects the upstream resource; or,

if the uplink resource is overlapped with the measurement gap after TA is advanced in the time domain, the network equipment does not blindly detect the uplink resource; or,

if the uplink resource is judged (or determined/judged) not to overlap with the measurement gap after TA is advanced in the time domain, the network equipment blindly detects the uplink resource; or,

etc.

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

In addition, the measurement gap may be one measurement slot before the uplink resource. It will be appreciated that since the measurement gap may be periodically configured, the measurement slot is a measurement slot that is temporally located before the uplink resource when determining whether there is an overlap between the time domain position after the advance TA of the uplink resource and the time domain position of the measurement gap.

It should be noted that, the initial time domain position of the measurement gap may also be located after the initial time domain position after the uplink resource advances TA, but the initial time domain position of the measurement gap may be located before the end time domain position after the uplink resource advances TA, so long as there is an overlap between the time domain position of the measurement gap and the time domain position after the uplink resource advances TA.

As can be seen, for the terminal device, the embodiment of the present application introduces a criterion for determining availability (or validity) of uplink resources, that is, whether the time domain position after the uplink resources advance TA overlaps with the time domain position of the measurement gap, so that the terminal device can determine which uplink resources can be used for data transmission according to the criterion, thereby being beneficial to ensuring that the data transmission is successful to improve the robustness of the NTN communication system.

Similarly, for the network device, the embodiment of the application introduces a criterion for uplink resource monitoring (or availability/validity), that is, whether the time domain position of the uplink resource after the advance TA overlaps with the time domain position of the measurement gap, so that the network device can determine which uplink resources are unavailable for data transmission by the terminal device according to the criterion. Therefore, the network equipment can avoid blind detection on the uplink resources, thereby being beneficial to saving the energy consumption of the network equipment.

To achieve the above technical solution, further explanation is given below on other contents, concepts and meanings that may be related to the technical solution.

1. Configuring uplink resources and measurement gaps

It should be noted that, the terminal device may receive various configuration information issued by the network device in a process of cell search, cell access, cell residence, random access, uplink and downlink resource scheduling, and the like. The various configuration information includes resource configuration information (such as time-frequency domain resource position, period, time-frequency domain resource size, etc. for configuring uplink resources) and resource configuration information (such as time-domain resource position, period, time length, etc. for configuring measurement gaps) for configuring measurement gaps.

In addition, in some embodiments, the uplink resource may be a preconfigured uplink resource, which is specifically described in the foregoing "7, preconfigured resource transmission", and will not be described in detail.

2. TA advanced by uplink resource in time domain

In combination with the content in the above-mentioned "TA in NTN communication system", the TA advanced in the time domain by the uplink resource may be a full TA. Thus, the terminal device needs to calculate the UE-specific TA from 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. Overlapping of

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

In this embodiment, the starting time domain position of the uplink resource may be a starting time unit of the uplink resource, and the ending position of the uplink resource may be an ending time unit of the uplink resource. In this case, a time unit is understood to mean the granularity of the communication between the terminal device and the network device in the time domain, i.e. the terminal device and the network device communicate in the time domain with the granularity of the time unit. For example, the time unit may be a subframe, a slot, a symbol, a mini-slot, etc., which is not limited thereto. Taking time units as an example of time slots. The starting position of the uplink resource is the starting time slot of the uplink resource, and the ending time domain position of the uplink resource can be the ending time slot of the uplink resource. Similarly, in the case where the time unit is a symbol, the starting position of the uplink resource is the starting symbol of the uplink resource, and the ending time domain position of the uplink resource may be the ending symbol of the uplink resource.

Similarly, the starting time-domain position of the measurement gap may be the starting time unit of the measurement gap; the end time domain position of the measurement gap may be an end time unit of the measurement gap. Taking time units as an example of time slots. The starting position of the measurement gap is the starting time slot of the uplink resource, and the ending time domain position of the measurement gap can be the ending time slot of the uplink resource.

Thus, for overlapping, the following can be understood:

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

2) The initial time domain position (or the end time domain position) of the uplink resource after TA is advanced is positioned in the measurement gap;

3) The time interval between the initial time domain position of the uplink resource after TA is advanced and the initial time domain position of the measurement gap is smaller than the duration of the measurement interval; or, the end time domain position after the uplink resource advances by TA is positioned in the measurement interval.

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

For example, as shown in fig. 9. In fig. 9 (a), the uplink resource 910 is advanced by TA, so that the uplink resource 910 is located at the time domain position 920 after being advanced by TA, that is, the uplink resource 910 is located in the measurement gap 930 after being advanced by TA, that is, the uplink resource 910 is completely overlapped with the part of the measurement gap 930 after being advanced by TA, and L is the duration of the measurement gap. In fig. 9 (b), the uplink resource 910 is advanced by TA, resulting in the time domain location 920, and the time domain location 920 partially overlaps with the measurement gap.

4. Transmitting data without using the uplink resource and transmitting data using the uplink resource

For transmitting data without using the uplink resource, it can be understood as follows:

1) Transmitting data without (or without) using uplink resources;

2) Transmitting data to the network device without using (or employing) the uplink resources;

3) The uplink resource is not utilized (or not adopted) for data transmission;

4) Data transmission is not carried out at the time domain position after the uplink resource advances by TA;

5) The uplink resource is not adopted (or not used) to transmit data after TA is advanced in time domain.

Similarly, the description of using the uplink resource to transmit data is similar to that described above, and will not be repeated.

It should be noted that, data is not transmitted using or using uplink resources, and here, data may be understood as uplink data, that is, data transmitted from a terminal device to a network device.

5. Blindly detecting the uplink resource and blindly detecting the uplink resource

For non-blind detection of the uplink resource, it can be understood as follows:

1) Blind detection is not carried out on the uplink resource;

2) And (5) blind detection is not carried out on the uplink resource.

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

1) Performing blind detection on the uplink resource;

2) And performing blind detection on the uplink resource.

6. How to determine whether the time domain position after the advance TA of the uplink resource overlaps with the time domain position of the measurement gap or whether the measurement gap overlapping with the time domain position after the advance TA of the uplink resource exists

It should be noted that, the embodiment of the present application may make the determination in the following manner:

1) According to K_offset, determining that the time domain position of the uplink resource after TA is advanced overlaps (or does not overlap) with the time domain position of the measurement gap, specifically, see the related description in the following mode one;

2) According to K_offset, determining that there is (or does not exist) a measurement gap overlapped with a time domain position after an uplink resource advances TA, specifically, see the related description in the following second mode;

3) According to TA, determining that the time domain position of the uplink resource after TA is advanced overlaps (or does not overlap) with the time domain position of the measurement gap, specifically, see the related description in the following third mode;

4) And judging whether a measurement gap overlapped with the time domain position after the advance TA of the uplink resource exists (or not) according to the TA, and particularly referring to the related description in the mode four.

Of course, in the embodiment of the present application, parameters or information used for determining whether there is an overlap with a measurement gap in the time domain after determining that an uplink resource advances to the TA, or whether there is an overlap with a measurement gap in the time domain after determining that an uplink resource advances to the TA, are not limited, whether parameters or information used for determining that a terminal device and a network device overlap with each other are the same, and whether a determination mode is the same are not limited, so long as determination results of the terminal device and the network device are consistent.

The following describes the above modes in detail.

Mode one:

as can be seen from the above description of "k_offset" in the NTN communication system, k_offset may be an additional time interval (or delay value/offset), and may be an additional scheduling delay value configured by the network device to the terminal device. The k_offset may be in units of milliseconds, slots, or subframes. The k_offset may be configured to the terminal device through system information or RRC dedicated signaling.

In addition, the embodiment of the present application may consider the k_offset as a maximum value of the TA, that is, the TA corresponding to the terminal device when transmitting data using the uplink resource will not exceed the k_offset.

Meanwhile, in order to determine (or determine/determine) whether the time domain position after the uplink resource advances by TA and the time domain position of the measurement gap overlap according to the k_offset, M, L, T0, T1, toffset, etc. may also be introduced in the embodiment of the present application.

1) 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 one measurement slot located before the uplink resource in the time domain.

As can be seen from the above description of "overlapping", the time-frequency domain resource positions of the uplink resource may include a start time domain position and an end time domain position, and the time domain resource positions of the measurement gap may include a start time domain position and an end time domain position. For this, M may be the following:

(1) m is the time interval between the starting time domain position (or ending time domain position) of the uplink resource and the starting time domain position of the measurement gap;

(2) m is the time interval between the starting time domain position (or ending time domain position) of the uplink resource and the ending time domain position of the measurement gap.

2) Concept of L

L may be the length of the measurement gap, i.e. the length of the measurement gap in the time domain.

As can be seen from the above description of "1, configuration of uplink resources and measurement gaps", the L may be configured by the network device to the terminal device. In addition, the L may also be pre-defined or pre-configured by a protocol, which is not particularly limited.

The unit of L may be milliseconds.

3) Concept of T0

T0 may be a pre-configured duration. For example, the T0 may be network-configured to the terminal device, may be pre-defined or pre-configured by a protocol, and is not particularly limited.

The unit of T0 may be a millisecond, a slot, or a 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 a cell level configuration

When T0 is a configuration at the cell level (i.e., a T0 value at the cell level), the network device may determine the T0 according to a maximum differential delay value corresponding to a coverage area of a serving cell of the terminal device. The network device may then configure the T0 to the terminal device.

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

In addition, the maximum differential delay value corresponding to the coverage area of the serving cell may be understood by combining the content of the foregoing "maximum differential delay value in 3, NTN communication system", which will not be described in detail.

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

T0≥2T；

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

(2) T0 is the configuration of the beam level

Similarly, when T0 is a configuration of a beam level (i.e., a T0 value of the beam level), the network device may determine the T0 according to a maximum differential delay value corresponding to a coverage area of a current service beam of the terminal device. The network device may then configure the T0 to the terminal device.

In addition, the maximum differential delay value corresponding to the coverage area of the current service beam may be understood by combining the content of the above "maximum differential delay value in 3 and NTN communication systems", which will not be described in detail.

In some embodiments, for how to determine this T0 according to the maximum differential delay value corresponding to the coverage area of the current service beam of the terminal device, it may be determined according to the following formula:

T0≥2T；

wherein 2T represents 2 times of T, and T is the maximum differential delay value corresponding to the coverage area of the current service beam of the terminal device. That is, T0 is not less than 2 times the maximum differential delay value corresponding to the coverage area of the current service beam of the terminal device.

(3) Configuration of terminal equipment level

When T0 is configured at the level of the terminal device (i.e., the T0 value at the level of the UE), the network device may determine the T0 according to the TA reported by the terminal device, and may determine the T0 according to the location information reported by the terminal device.

When the terminal device reports the TA, the TA may be a full TA or a UE-specific TA. Because the network device has the common TA, the network device can calculate the full TA according to the UE-specific TA and the common TA reported by the terminal device.

When the terminal device reports the position information, the network device can calculate the UE-specific TA according to the position information and the satellite ephemeris, and then calculate the full TA.

In addition, although the current full TA (obtained by the terminal device or calculated by the network device from the UE-specific TA reported by the terminal device) obtained by the network device may be changed due to the continuous motion change of the satellite, the satellite runs along a predetermined orbit and has a known moving speed and orbit height. Based on this, the network device may determine a fixed variable duration (e.g., obtained by querying a mapping table with the current full TA) according to the current full TA, where the fixed variable duration is T0.

4) Concept of T1

T1 may be a pre-configured duration. For example, the T0 may be network-configured to the terminal device, may be pre-defined or pre-configured by a protocol, and is not particularly limited.

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

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

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

T1＝T0+L。

as can be seen from the above-described "2) L concept" and "3) T0 concept", T1 may be a cell-level configuration, a beam-level configuration, or a terminal device-level configuration. The same thing can be said to be as follows:

(1) t1 is a cell level configuration

When T1 is a configuration at a cell level (i.e., a T1 value at a cell level), the network device may determine T1 according to a maximum differential delay value corresponding to a coverage area of a serving cell of the terminal device and a duration of a measurement gap. The network device may then configure the T1 to the terminal device.

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

T1≥2T+L；

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

(2) T1 is the configuration of the beam level

Similarly, when T1 is a configuration of a beam level (i.e., a T1 value of the beam level), the network device may determine T1 according to a maximum differential delay value corresponding to a coverage area of a current service beam of the terminal device and a duration of the measurement gap. The network device may then configure the T1 to the terminal device.

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

T0≥2T+L；

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

(3) Configuration of terminal equipment level

When T1 is configured at the terminal device level (i.e., the T1 value at the UE level), the network device may determine the T1 according to the TA and the duration of the measurement gap reported by the terminal device, and may determine the T1 according to the location information and the duration of the measurement gap reported by the terminal device, which is specifically consistent with the description in the concept of "3) T0" above, which is not repeated herein.

5) Concept of Toffset

Toffset may be a preconfigured time offset (or duration/delay value). For example, the Toffset may be network-configured to the terminal device, may be pre-defined or pre-configured by a protocol, and is not particularly limited.

The unit of Toffset may be a millisecond, a slot, or a subframe.

Note that Toffset is similar to T0 of the above-described configuration at the terminal device level. Although the current full TA obtained by the network device (either as reported by the terminal device or as calculated by the network device from the UE-specific TA reported by the terminal device) may change due to the constant motion change of the satellite, the satellite runs along a predetermined orbit and has a known movement speed and orbit height. Based on this, the network device may determine a fixed variable duration (e.g., obtained by querying a mapping table with the current full TA) according to the current full TA, where the fixed variable duration is Toffset.

That is, toffset may be determined by the network device according to the satellite moving speed or the satellite orbit height, may be determined according to the TA or the position information reported by the terminal device, may be determined according to the TA, the satellite moving speed, and the satellite orbit height reported by the terminal device, and may be determined according to the position information, the satellite moving speed, and the satellite orbit height reported by the terminal device, which are not particularly limited.

In summary, in "mode one", the terminal device or the network device may perform the determination according to k_offset and M, may perform the determination according to k_ offset, M, T0 and L, may perform the determination according to k_offset, M and T1, whether they overlap, and so on. The following is a detailed description.

6) It should be noted that whether the time domain position after the uplink resource advances TA and the time domain position of the measurement gap overlap is determined according to k_offset and M, and the embodiment of the present application may determine according to the magnitude relation between k_offset and M. The size relationship between k_offset and M may be as follows:

①M≤K_offset

it should be noted that, for an uplink resource, if M is less than or equal to k_offset, it is indicated 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 data transmission by the terminal device using the uplink resource may be greater than M, which may cause the time domain position of the uplink resource after the TA is advanced to overlap with the time domain position of the measurement gap, so that the terminal device does not use the uplink resource to transmit data, and the network device does not blindly detect the uplink resource.

For example, taking M as an example of the time interval between the starting time domain position of the uplink resource and the ending time domain position of the measurement gap, as shown in fig. 10, when m+_k_offset, it is indicated that TA may be greater than M. Therefore, the uplink resource 1010 is advanced by the TA, so that the uplink resource 1010 is advanced by the TA and then located at the time domain position 1020, i.e., the uplink resource 1010 is advanced by the TA and then located in the measurement gap 1030, i.e., the uplink resource 1010 is advanced by the TA and then overlaps with the measurement gap 1030.

②M＞K_offset

Similarly, for an uplink resource, if M > k_offset exists, i.e., M is not greater than or equal to k_offset, it is indicated that the time interval between the uplink resource and the measurement gap is greater than 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 when transmitting data using the uplink resource will be smaller than M, so that the time domain position of the uplink resource after advancing TA and the time domain position of the measurement gap do not overlap, so that the terminal device can transmit data using the uplink resource, and the network device can blindly detect the uplink resource.

7) Judging whether the time domain position after the uplink resource advances TA overlaps with the time domain position of the measurement gap according to K_ offset, M, T0 and L

It should be noted that, in the embodiment of the present application, the determination may be performed according to the magnitude relationship between k_ offset, M, T0 and L. The size relationship between k_ offset, M, T0 and L may be as follows:

①K_offset-T0-L≤M≤K_offset

it should be noted that, for an uplink resource, if k_offset-T0-L is less than or equal to M and less than or equal to k_offset, 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 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, the present embodiment may consider k_offset as a maximum value of TA and k_offset-T0 as a minimum value of TA. Therefore, the TA corresponding to the data transmission by the terminal device using the uplink resource may be greater than M, so that the time domain position of the uplink resource after the TA is advanced may overlap with the time domain position of the measurement gap, so that the terminal device does not use the uplink resource to transmit data, and the network device does not blindly detect the uplink resource.

For example, as shown in fig. 11, M is a time interval between a start time domain position of the uplink resource 1110 and an 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 is less than or equal to k_offset, the measurement gap will move toward the uplink resource 1120, resulting in the uplink resource 1120 overlapping with the measurement gap.

When m=k_offset-T0-L, the starting time domain position of the measurement gap is at position 1140. At this time, if K_offset-T0-L is less than or equal to M, the measurement gap will move towards the uplink resource 1120, resulting in the uplink resource 1120 overlapping the measurement gap.

②M＜K_offset-T0-L

Similarly, for an uplink resource, if M < K_offset-T0-L exists, that is, K_offset-T0-L is not less than M and not more than K_offset, the time interval between the uplink resource and the measurement gap is smaller than K_offset-T0-L, wherein M is the time interval between the uplink resource and the measurement gap. k_offset-T0 is considered as a minimum value of TA, and although the TA corresponding to the terminal device when transmitting data using the uplink resource may be greater than M, it may still cause the time domain position after the uplink resource advances by TA to be not overlapped with the time domain position of the measurement gap, so that the terminal device may transmit data using the uplink resource, and the network device may blindly check the uplink resource.

③M＞K_offset

Similarly, for an uplink resource, if M > K_offset exists, that is, K_offset-T0-L is not greater than or equal to M and not greater than K_offset, the time interval between the uplink resource and the measurement gap is greater than 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 when transmitting data using the uplink resource will be smaller than M, so that the time domain position of the uplink resource after advancing TA and the time domain position of the measurement gap do not overlap, so that the terminal device can transmit data using the uplink resource, and the network device can blindly detect the uplink resource.

8) Judging whether the time domain position after the uplink resource advances TA overlaps with the time domain position of the measurement gap according to K_offset, M and T1

It should be noted that, in the embodiment of the present application, the judgment may be performed according to the magnitude relation among k_offset, M and T1. Wherein the size relationship among K_offset, M and T1 may be as follows

①K_offset-T1≤M≤K_offset

It should be noted that, for an uplink resource, if k_offset-t1 is less than or equal to M and less than or equal to k_offset, 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 is 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, the present embodiment may consider k_offset as a maximum value of TA and k_offset-t1+l as a minimum value of TA. Therefore, the TA corresponding to the data transmission by the terminal device using the uplink resource may be greater than M, so that the time domain position of the uplink resource after the TA is advanced may overlap with the time domain position of the measurement gap, so that the terminal device does not use the uplink resource to transmit data, and the network device does not blindly detect the uplink resource.

②M＜K_offset-T1

Similarly, for an uplink resource, if M < K_offset-T1 exists, that is, K_offset-T1 is not less than M and not more than K_offset, the time interval between the uplink resource and the measurement gap is smaller than K_offset-T1, wherein M is the time interval between the uplink resource and the measurement gap. K_offset-t1+l is regarded as a minimum value of TA, and although the TA corresponding to the terminal device when transmitting data using the uplink resource may be greater than M, the time domain position of the uplink resource after the TA is advanced may still not overlap with the time domain position of the measurement gap, so that the terminal device may transmit data using the uplink resource, and the network device may blindly check the uplink resource.

③M＞K_offset

Similarly, for an uplink resource, if M > k_offset exists, that is, k_offset-t1 is not less than or equal to M and not more than k_offset, it indicates that the time interval between the uplink resource and the measurement gap is greater than 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 when transmitting data using the uplink resource will be smaller than M, so that the time domain position after the uplink resource advances TA and the time domain position of the measurement gap do not overlap, so that the terminal device can transmit data using the uplink resource, and the network device can blindly detect the uplink resource.

Mode two:

it should be noted that, for an uplink resource, if k_offset-T0-L is equal to or less than M is equal to or less than k_offset, it is noted that there may be a measurement gap overlapping with a time domain position after the uplink resource advances by TA, 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.

②M＜K_offset-T0-L

Similarly, for an uplink resource, if M < k_offset-T0-L exists, that is, k_offset-T0-L is not greater than or equal to M and less than or equal to k_offset, it is indicated that there may not exist a measurement gap overlapping with a time domain position of the uplink resource after TA is advanced, so that the terminal device may transmit data using the uplink resource, and the network device may blindly test the uplink resource.

③M＞K_offset

Similarly, for an uplink resource, if M > k_offset exists, that is, k_offset-T0-L is not greater than or equal to M and not greater than k_offset, it is indicated that there may not exist a measurement gap overlapping with the time domain position of the uplink resource after the advance TA, so that the terminal device may transmit data by using the uplink resource, and the network device may blindly detect the uplink resource.

3) Determining whether a measurement gap overlapped with a time domain position after the advance TA of the uplink resource exists according to K_offset, M and T1

It should be noted that, in the embodiment of the present application, the judgment may be performed according to the magnitude relation among k_offset, M and T1. The size relationship among k_offset, M, and T1 may be as follows:

①K_offset-T1≤M≤K_offset

it should be noted that, for an uplink resource, if k_offset-t1 is equal to or greater than M and equal to or greater than k_offset, it is noted that there may be a measurement gap overlapping with a time domain position of the uplink resource after the advance TA, 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.

②M＜K_offset-T1

Note that the "mode two" and the "mode one" are implemented in the same manner. Therefore, the details of the "mode two" may be referred to as "mode one" specifically, and will not be described herein.

Mode three:

in "mode three", in order to determine (or determine/determine) whether or not the time domain position after the uplink resource is advanced by TA overlaps with the time domain position of the measurement gap, M, L, toffset may be introduced in the embodiment of the present application. The specific description of M, L, toffset is the same as that of the above-mentioned "mode one", and will not be repeated here.

Similarly, in "mode three", the terminal device or the network device can determine whether or not to overlap according to TA, M, toffset and L. The following is a detailed description. 1) Determining whether the time domain position of the uplink resource after TA is advanced overlaps with the time domain position of the measurement gap according to TA, M, toffset and L

It should be noted that, in the embodiments of the present application, the determination may be made according to the magnitude relationship between TA, M, toffset and L.

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 is less than or equal to M and less than or equal to ta+toffset, it means that the time interval between the uplink resource and the measurement gap is less than or equal to ta+toffset, and the time interval between the uplink resource and the measurement gap 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, the embodiment of the present application may consider ta+toffset as a maximum value of TA, and TA-Toffset as a minimum value of TA. Therefore, the TA corresponding to the data transmission by the terminal device using the uplink resource may be greater than M, so that the time domain position of the uplink resource after the TA is advanced may overlap with the time domain position of the measurement gap, so that the terminal device does not use the uplink resource to transmit data, and the network device does not blindly detect the uplink resource.

For example, as shown in fig. 12, the terminal device may report TA or location information to the network device, and the network device determines Toffset according to the TA or location information and issues Toffset to the terminal device. Where M is the time interval between the starting time domain position of the uplink resource 1210 and the ending time domain position of the measurement gap. When m=ta+toffset, the end time domain position of the measurement gap is at position 1230. At this time, if M is less than or equal to ta+toffse, the measurement gap will move to the uplink resource 1220, so that the uplink resource 1220 will overlap with the measurement gap.

When m=ta-Toffset-L, the starting time domain position of the measurement gap is at position 1240. At this time, if TA-Toffset-L is less than or equal to M, the measurement gap will move to the uplink resource 1220, so that the uplink resource 1220 will overlap with the measurement gap.

②M＜TA-Toffset-L

Similarly, for an uplink resource, if M is less than TA-Toffset-L, i.e. TA-Toffset-L is not less than M and not more than TA+Toffset, the time interval between the uplink resource and the measurement gap is smaller than TA-Toffset-L, where M is the time interval between the uplink resource and the measurement gap. The TA-Toffset is regarded as a minimum value of TA, and although the TA corresponding to the terminal device when transmitting data using the uplink resource may be greater than M, the time domain position of the uplink resource after advancing the TA may still not overlap with the time domain position of the measurement gap, so that the terminal device may transmit data using the uplink resource, and the network device may blindly detect the uplink resource.

③M＞TA+Toffset

Similarly, for an uplink resource, if M > TA+Toffset exists, that is, TA-Toffset-L is not less than or equal to M and not more than TA+Toffset exists, the time interval between the uplink resource and the measurement gap is larger 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 transmitting data by using the uplink resource will be less than M, so that the time domain position of the uplink resource after advancing TA and the time domain position of the measurement gap do not overlap, so that the terminal device can transmit data by using the uplink resource, and the network device can blindly detect the uplink resource.

Mode four: in "fourth mode", in order to determine (or determine/determine) whether or not there is a measurement gap overlapping with the time domain position after the advance TA of the uplink resource, M, L, toffset and the like may be introduced in the embodiment of the present application. The specific description of M, L, toffset is the same as that of the above-mentioned "mode one", and will not be repeated here.

Similarly, in "mode four", the terminal device or the network device may determine whether there is an overlapping measurement gap according to TA, M, toffset and L, and so on. The following is a detailed description.

1) Determining whether there is a measurement gap overlapping with the time domain position after the advance TA of the uplink resource according to TA, M, toffset and L

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 is less than or equal to M and less than or equal to ta+toffset, it is noted that there may be a measurement gap overlapping with a time domain position of the uplink resource after TA is advanced, 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.

②M＜TA-Toffset-L

Similarly, for an uplink resource, if M is less than TA-Toffset-L, that is, TA-Toffset-L is not less than or equal to M and less than or equal to TA+toffset, it is indicated that there may not exist a measurement gap overlapping with the time domain position of the uplink resource after TA is advanced, so that the terminal device may send data by using the uplink resource, and the network device may blindly detect the uplink resource.

③M＞TA+Toffset

Similarly, for an uplink resource, if M > ta+toffset exists, that is, TA-Toffset-L is not less than or equal to M and not more than ta+toffset exists, it is indicated that there may not exist a measurement gap overlapping with the time domain position of the uplink resource after advancing TA, so that the terminal device may send data by using the uplink resource, and the network device may blindly detect the uplink resource.

The "fourth mode" and the "third mode" are specifically the same implementations. Therefore, the details of the "mode four" may be specifically referred to as "mode three", which will not be described herein.

In summary, the communication method according to the embodiment of the present application will be described in detail below taking a decision based on TA or k_offset as an example.

Fig. 13 is a schematic flow chart of a communication method according to an embodiment of the present application, which specifically includes the following steps:

S1310, the terminal equipment receives resource configuration information from the network equipment, wherein the resource configuration information is used for configuring uplink resources.

Correspondingly, the network device sends the resource configuration information to the terminal device.

S1320, the terminal equipment judges that the time domain position of the uplink resource after advancing the TA overlaps with the time domain position of the measurement gap according to the TA or the K_offset, and does not use the uplink resource to send data, wherein the measurement gap is used for signal measurement.

Correspondingly, the network device determines that the time domain position of the uplink resource after advancing the TA overlaps with a measurement gap according to the TA or the K_offset, and does not monitor the uplink resource to send data, wherein the measurement gap is used for signal measurement.

It should be noted that, in some embodiments, in a case where an uplink resource configured by the network device for the terminal device is a periodic resource, the terminal device or the network device may determine for each uplink resource in the periodic resource. For example, when the terminal device needs to use an uplink resource of a certain period, a determination is made for the uplink resource. The network device may determine the uplink resource of a certain period before blind detection of the uplink resource is required.

It can be seen that, in this embodiment of the present application, for a terminal device, a criterion for determining availability (or validity) of an uplink resource is introduced in this embodiment, that is, whether there is an overlap between a time domain position after an advance TA of the uplink resource and a time domain position of a measurement gap is determined according to TA or k_offset, so that when there is an overlap between the time domain position after the advance TA of the uplink resource and the time domain position of a measurement slot, the terminal device may not use the uplink resource to perform data transmission, thereby ensuring that data transmission is successful to improve communication reliability.

For network equipment, the embodiment of the application introduces an uplink resource monitoring (or availability/effectiveness) judging criterion, namely whether the time domain position after the uplink resource advances TA and the time domain position of the measurement gap are overlapped or not is judged according to TA or K_offset, so that when the time domain position after the uplink resource advances TA and the time domain position of the measurement time slot are overlapped, the network equipment can not blindly detect the uplink resource, thereby being beneficial to reducing the blind detection times of the network equipment and achieving the purpose of saving power consumption.
