Description

Data transmission method, chip, terminal and storage medium

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a data transmission method, a chip, a terminal and a storage medium.

Background

In a Non-Terrestrial network (NTN), when transmitting uplink data, a terminal performs advanced transmission based on a Timing Advance (TA) value, so as to ensure synchronization of an uplink and a downlink. For example, in a process of scheduling a Physical Uplink Shared Channel (PUSCH) in an existing Physical Downlink Control Channel (PDCCH), a Downlink Control Information (DCI) in the PDCCH indicates a scheduled delay value of a terminal, thereby determining a transmission resource position of the PUSCH.

However, in a satellite communication network, since there is a large propagation delay for transmission between a terminal and a satellite, the terminal generally needs to perform an advance transmission based on a determined timing advance in order to align uplink and downlink timings. The scheduling delay value indicated in the DCI is usually set to be small, and cannot meet the requirement of a large timing advance in a satellite scene, that is, based on the existing scheduling delay, the terminal cannot perform timing advance transmission. This causes a problem in time synchronization between the terminal and the satellite, and thus reduces transmission efficiency between the terminal and the satellite.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

In NTN, for example, for a satellite communication network, a cell may typically contain multiple beams (beams). Due to the rapid movement of the satellite, the terminal needs to perform beam switching frequently. When a terminal (e.g., an internet of things device) accesses through the satellite communication network, a beam management mechanism is required to allocate communication resources. However, there is no corresponding beam management mechanism in current physical network protocols.

Through research on the above problems, the inventors found that carrier management is supported in the internet of things, that is, communication resources are generally allocated in units of carriers in the internet of things. For example, in an internet of things network, a single frequency point cell usually has a bandwidth of 180kHZ, and the remaining traffic channel capacity is small except for a Narrowband Primary Synchronization Signal (NPSS), a Narrowband Secondary Synchronization Signal (NSSS), and a System Information Block (SIB). Therefore, in order to support a large number of terminals, it is necessary to increase the network capacity by using a plurality of frequency points. The cell may include a plurality of non-anchor carriers that only carry NPDCCH and NPDSCH, but not NPSS, NSSS, and NPBCH, in addition to anchor carriers that support simultaneous carrying NPSS, NSSS, a Narrowband Physical Broadcast Channel (NPBCH), and a Narrowband Physical Downlink Control Channel (NPDCCH). The frequency spectrum bandwidth of each carrier is 180kHz, and the maximum frequency spectrum span of all carriers in a cell does not exceed 20 MHz. The terminal may perform data transmission on the non-anchor carrier.

Thus, a mapping relationship may be established between carriers and beams, e.g., one beam for each carrier, e.g., carrier 1 for beam 1 and carrier 2 for beam 2. Therefore, beam switching can be realized through carrier switching, and beam management is further realized.

However, when the network side switches between different beams, the transmission delay between the terminal and the satellite is different. At present, only scheduling delay is considered on a network side, and transmission delay between the terminal and the satellite is not considered, so that a problem is brought to time synchronization between the terminal and the satellite, and transmission efficiency between the terminal and the satellite is further influenced.

Based on the above problem, an embodiment of the present application provides a data transmission method.

The data transmission method provided by the embodiment of the present application is now described with reference to fig. 1 to 10. Fig. 1 is an application scenario provided in the embodiment of the present application, and referring to fig. 1, the application scenario includes a terminal 100 and a satellite 200. It is understood that the satellite 200 is a network-side device, and does not limit the embodiments of the present application, and in some embodiments, the network-side device may also be embodied in other forms.

A terminal can also be called a terminal device, User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. The terminal may be a Station (ST) in a WLAN, and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a vehicle networking terminal, a computer, a laptop computer, a handheld communication device, a handheld computing device, a satellite radio, a Wireless modem card, a television Set Top Box (STB), a Customer Premises Equipment (CPE), and/or other devices for communicating over a Wireless system, as well as a next generation communication system, e.g., a Mobile terminal in a 5G Network or a future-evolution Public Land Mobile Network (Public Land Mobile Network, PLMN) mobile terminals in the network, etc. The terminal may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable intelligent device has the advantages that the generalized wearable intelligent device is complete in function and large in size, can realize complete or partial functions without depending on a smart phone, such as a smart watch or smart glasses, and only is concentrated on a certain application function, and needs to be matched with other devices such as the smart phone for use, such as various smart bracelets for monitoring physical signs, smart jewelry and the like. The terminal can also be an internet of things device.

The embodiment of the present application does not specifically limit the specific form of the terminal.

Fig. 2 is a schematic flowchart of an embodiment of a data transmission method provided in the present application, including:

in step 101, the satellite 200 transmits timing offset configuration information.

Specifically, the satellite 200 may transmit the timing offset configuration information in a broadcast manner. For example, the satellite 200 may broadcast a system broadcast message (e.g., SIB) through NPBCH, where the SIB may carry the above-mentioned timing offset configuration information. The timing offset configuration information may include a plurality of timing offsets, and each timing offset may correspond to one uplink carrier. It can be understood that, since each uplink carrier corresponds to one beam, the timing offset of each uplink carrier may also correspond to one beam, so that different uplink carriers or beams may correspond to different timing offsets. Table 1 is a timing offset configuration information table, and as shown in table 1, the timing offset configuration information table may include mapping relationships between uplink carriers, beams, and timing offsets.

TABLE 1

Uplink carrier ID	Beam ID	Timing offset
			Uplink carrier 1	Beam 1	T_offset1
Uplink carrier 2	Beam 2	T_offset2
			…	…	…

It should be understood that table 1 above only shows an exemplary mapping relationship between uplink carriers, beams and timing offsets, and does not limit the embodiments of the present application. In some embodiments, the timing offset configuration information may also include a mapping relationship between an uplink carrier and a timing offset or a mapping relationship between a beam and a timing offset, where the mapping relationship between the uplink carrier and the beam may be configured in the terminal 100 in advance.

It should be noted that the timing offset of each uplink carrier can be determined by the transmission delay between the terminal 100 and the satellite 200.

In addition, table 1 above only exemplarily represents the identity of the uplink carrier by an ID manner, and does not limit the embodiment of the present application, and in some embodiments, the identity of the uplink carrier may also be identified by an index (index) manner.

Optionally, the satellite 200 may also transmit the above timing offset configuration information through RRC dedicated signaling. For example, after the RRC connection is established between the terminal 100 and the satellite 200, the satellite 200 may send RRC dedicated signaling to the terminal 100, where the RRC dedicated signaling may carry the timing offset configuration information. For specific RRC dedicated signaling, reference may be made to 3GPP related protocols, which are not described herein again.

In step 102, the terminal 100 receives and stores the timing offset configuration information transmitted from the satellite 200.

In step 103, the satellite 200 prepares to switch from the first beam to the second beam, and transmits the ID of the second carrier to the terminal 100 through the first beam.

Specifically, since frequent switching of beams used between the satellite 200 and the terminal 100 may occur due to rapid movement of the satellite 200, the satellite 200 may notify the switched target beam through a downlink message. In a specific implementation, the downlink message may be DCI or a Random Access Response Grant (RAR Grant), the first beam may be any one of the beam resources of the satellite 200, and the first beam may be a beam before handover, for example, the first beam may be beam 1 in table 1. The first beam corresponds to a first carrier, which may be one of the carrier resources of the terminal 100, e.g., carrier 1 in table 1. The second beam may be another beam in the beam resources of the satellite 200 and the second beam may be the target beam after the handover. For example, the second beam may be beam 2 in table 1. The second beam corresponds to a second carrier, which may be another carrier in the carrier resources of the terminal 100, e.g., carrier 2 in table 1.

For example, the satellite 200 may send DCI through the PDCCH where the first beam is located, or send an RAR Grant through a Random Access (RA) process, where the specific RA process may refer to a 3GPP related protocol, and details are not described herein. Wherein the DCI or RAR Grant may include an ID of the second carrier.

Optionally, the DCI or RAR Grant may further include a scheduling delay.

It should be understood that the above example only illustrates a manner in which the downlink message (e.g., DCI or RAR Grant) includes the ID of the second carrier, and does not constitute a limitation to the embodiment of the present application, and in some embodiments, since the uplink carrier has a mapping relationship with a beam, the ID of the second carrier may also be replaced by the ID of the second beam.

In step 104, the terminal 100 receives the ID of the second carrier transmitted from the satellite 200, and determines the data transmission time based on the ID of the second carrier.

Specifically, since the satellite 200 transmits the DCI or the RAR Grant through the first beam, the terminal 100 may receive the DCI or the RAR Grant through the first carrier based on the mapping relationship between the uplink carrier and the beam. When the terminal 100 receives the DCI or the RAR Grant transmitted by the satellite 200, the scheduling delay in the DCI or the RAR Grant and the ID of the second carrier may be obtained.

Next, a timing offset (e.g., T _ offset2) corresponding to the second carrier may be obtained by querying in the stored timing offset configuration information based on the ID of the second carrier. After the timing offset of the second carrier is obtained, the data transmission time may be determined based on the scheduling delay and the timing offset of the second carrier. Illustratively, the data transmission time T is T _ start + T0+ T _ offset2, where T _ start is the start time, and T0 is the scheduling delay.

Optionally, since there is a carrier switching delay in the carrier switching process, the carrier switching delay may also be considered when calculating the data transmission time T. Illustratively, the data transmission time T is T _ start + T0+ T _ offset2+ T1, where T1 is the carrier switching delay.

Taking DCI as an example, as shown in fig. 3, the satellite 200 transmits DCI to the terminal 100 through a PDCCH where a first beam is located, and the terminal 100 receives the DCI transmitted by the satellite 200 through the first carrier based on a mapping relationship between an uplink carrier and the beam. The time when the terminal 100 completely receives the DCI is T _ start. After the terminal 100 completely receives the DCI, the terminal may acquire the scheduling delay T0 in the DCI and the timing offset T _ offset2 of the second carrier, and may transmit data at time T _ start + T0+ T _ offset 2. For example, data may be transmitted through the PUSCH on which the second carrier is located at time T _ start + T0+ T _ offset 2.

Optionally, after acquiring the timing offset T _ offset2 of the second carrier, the timing offset T _ offset1 of the first carrier may be further acquired. At this time, the above T _ offset1 and T _ offset2 may be compared.

If T _ offset1> -T _ offset2, the data transmission time T-T _ start + T0+ T _ offset 1;

if T _ offset1< ═ T _ offset2, the data transmission time T is T _ start + T0+ T _ offset 2.

It is understood that fig. 3 only illustrates the DCI scenario by way of example, and does not constitute a limitation to the embodiments of the present application. In some embodiments, the data transmission time may also be determined by means of the RAR Grant.

In step 105, the terminal 100 transmits data to the satellite 200 based on the data transmission time.

Specifically, when the terminal 100 determines the data transmission time, the terminal may transmit data to the satellite 200 at the data transmission time using the PUSCH in which the second carrier is located.

In the embodiment of the application, the network side configures the transmission delay based on each beam, when the network side switches to the target carrier, the terminal side determines the corresponding transmission delay based on the target carrier, and determines the data transmission time based on the transmission delay, so that the time synchronization between the terminal side and the network side can be realized, and the transmission efficiency between the terminal side and the network side can be further improved.

Fig. 4 is a schematic flowchart of another embodiment of a data transmission method provided in the present application, including:

in step 201, the satellite 200 transmits timing offset set configuration information.

Specifically, the satellite 200 may transmit the timing offset set configuration information in a broadcast manner. For example, the satellite 200 may broadcast a system broadcast message (e.g., SIB) through NPBCH, where the SIB may carry the above-mentioned timing offset set configuration information. The timing offset set configuration information may include a plurality of timing offset sets, each timing offset set may correspond to one uplink carrier, and each timing offset set may include a plurality of timing offsets. It can be understood that, since each uplink carrier corresponds to one beam, the timing offset set of each uplink carrier may also correspond to one beam, thereby realizing that different uplink carriers or beams may correspond to different timing offsets. Table 2 is a timing offset set configuration information table, which may include mapping relationships between uplink carriers, beams and timing offset sets, as shown in table 2.

TABLE 2

Uplink carrier ID	Beam ID	Timing offset set
			Uplink carrier 1	Beam 1	T_offset11，T_offset12
Uplink carrier 2	Beam 2	T_offset21，T_offset22
			…	…	…

It is to be understood that table 2 above only shows the number of timing offsets in the timing offset set by way of example, and does not constitute a limitation on the embodiments of the present application. In some embodiments, each set of timing offsets may also include 3 or more timing offsets.

Optionally, the satellite 200 may also transmit the above timing offset set configuration information through RRC dedicated signaling. For example, after the RRC connection is established between the terminal 100 and the satellite 200, the satellite 200 may send RRC dedicated signaling to the terminal 100, where the RRC dedicated signaling may carry the timing offset set configuration information.

In step 202, the terminal 100 receives and stores the timing offset set configuration information transmitted by the satellite 200.

In step 203, the satellite 200 prepares to switch from the first beam to the second beam, and transmits the ID and the index identifier of the second carrier to the terminal 100 through the first beam.

Specifically, the satellite 200 may send the ID and the index identifier of the second carrier to the terminal 100, where the ID and the index identifier of the second carrier may be carried by DCI or RAR Grant. The index identifies an index that characterizes a timing offset in the set of timing offsets. In a specific implementation, the index identifier may be indicated by a special field in DCI or RAR Grant. Illustratively, if the set of timing offsets includes 2 timing offsets, the special field may include 1 bit (e.g., the index identification may be 0 or 1). Taking uplink carrier 1 as an example, if the index flag is "0", a first timing offset (e.g., T _ offset11) may be indicated; if the index identification is "1," a second timing offset (e.g., T _ offset12) may be indicated.

Optionally, the DCI or RAR Grant may also carry a scheduling delay.

In step 204, the terminal 100 receives the ID and the index identifier of the second carrier sent by the satellite 200, and determines the data transmission time based on the ID and the index identifier of the second carrier.

Specifically, since the satellite 200 transmits the DCI or the RAR Grant through the first beam, based on the mapping relationship between the uplink carrier and the beam, the terminal 100 may receive the DCI or the RAR Grant through the first carrier. After receiving the DCI or RAR Grant transmitted by the satellite 200, the terminal 100 may obtain the scheduling delay, the ID of the second carrier, and the index identifier in the DCI or RAR Grant.

Next, a timing offset set corresponding to the second carrier may be obtained based on a timing offset set configuration information query by the ID of the second carrier. After acquiring the set of timing offsets for the second carrier, the timing offset in the set of timing offsets may be determined based on the index identifier (e.g., the timing offset may be T _ offset21 or T _ offset22 in the set of timing offsets for the second carrier), and the data transmission time may be determined based on the scheduling delay and the determined timing offset for the second carrier. For example, if it is determined that the timing offset in the timing offset set of the second carrier is T _ offset21, the data transmission time T is T _ start + T0+ T _ offset 21.

Optionally, since there is a carrier switching delay in the carrier switching process, the carrier switching delay may also be considered when calculating the data transmission time T. Illustratively, the data transmission time T is T _ start + T0+ T _ offset21+ T1, where T1 is the carrier switching delay.

In step 205, the terminal 100 transmits data to the satellite 200 based on the data transmission time.

In the embodiment of the application, the network side configures the transmission delay set based on each beam, when the network side switches to the target carrier, any one of the transmission delays can be selected from the transmission delay set, and the terminal side determines the sending time based on the transmission delay indicated by the network side, so that the flexibility of selecting the transmission delay can be improved, the time synchronization between the terminal side and the network side can be realized, and the transmission efficiency between the terminal side and the network side can be improved.

The above is described by taking the network side switching from the first beam to the second beam as an example through fig. 2-4, and the following is described by taking the cross-beam data transmission as an example through fig. 5-10.

Fig. 5 is a schematic flowchart of a data transmission method according to still another embodiment of the present application, including:

in step 301, the satellite 200 transmits timing offset configuration information.

Specifically, the satellite 200 may transmit the timing offset configuration information in a broadcast manner. For example, the satellite 200 may broadcast a system broadcast message (e.g., SIB) through NPBCH, where the SIB may carry the above-mentioned timing offset configuration information. The timing offset configuration information may include a plurality of timing offsets, and each timing offset may correspond to one uplink carrier. It can be understood that, since each uplink carrier corresponds to one beam, the timing offset of each uplink carrier may also correspond to one beam, so that different uplink carriers or beams may correspond to different timing offsets.

Optionally, the satellite 200 may also transmit the above timing offset configuration information through RRC dedicated signaling. For example, after the RRC connection is established between the terminal 100 and the satellite 200, the satellite 200 may send RRC dedicated signaling to the terminal 100, where the RRC dedicated signaling may carry the timing offset configuration information.

In step 302, the terminal 100 receives and stores the timing offset configuration information transmitted from the satellite 200.

In step 303, the satellite 200 sends instruction information to the terminal 100 through the first beam, instructing the terminal 100 to perform segmented transmission on one transmission block scheduled this time.

Specifically, in order to improve the utilization efficiency between the beams, the satellite 200 may segment the transmission block scheduled this time and then transmit the segmented transmission block on two beams (for example, the transmission block may be transmitted on a first beam and a second beam). In a specific implementation, the satellite 200 may send indication information to the terminal 100, where the indication information may be carried by DCI or RAR Grant. The indication information may include scheduling delay, an ID of the second carrier, and data segmentation information, where the data segmentation information is used to indicate a segmentation condition of a transport block scheduled this time and a corresponding condition of the segmented transport block and an uplink carrier. Table 3 is an example table of data division information.

TABLE 3

As shown in table 3, the data partitioning information may include a data identification field and a carrier ID field, where the data identification field is used to identify a partition manner of a Transport Block, for example, assuming that one Transport Block (TB) is 1024 bytes, if the Transport Block is partitioned, a first data segment with a length of 400 bytes (for example, a first byte is 0 and a last byte is 399) and a second data segment with a length of 624 bytes (for example, a first byte is 400 and a last byte is 1023) are obtained respectively. Wherein the first data segment corresponds to uplink carrier 1, that is, the terminal 100 may transmit the first data segment using a first carrier (e.g., the first carrier may be uplink carrier 1 in table 3, and the uplink carrier 1 corresponds to a first beam); and the second data segment corresponds to uplink carrier 2, that is, the terminal 100 may transmit the second data segment using the second carrier (e.g., the second carrier may be uplink carrier 2 in table 3, and uplink carrier 2 corresponds to the second beam).

It is understood that the above table 3 only illustrates an exemplary manner of segmenting data by the above related domains, and does not limit the embodiments of the present application, and in some embodiments, the data segmentation information may also include more or less domains.

In step 304, the terminal 100 receives the indication information transmitted from the satellite 200, and determines the data transmission time based on the indication information.

Specifically, since the satellite 200 transmits the DCI or the RAR Grant through the first beam, the terminal 100 may receive the DCI or the RAR Grant through the first carrier based on the mapping relationship between the uplink carrier and the beam. When receiving the DCI or RAR Grant transmitted by the satellite 200, the terminal 100 may acquire the indication information (e.g., scheduling delay, ID of the second carrier, and data segmentation information) in the DCI or RAR Grant.

Next, the timing offset configuration information may be queried based on the ID of the second carrier to obtain the timing offset corresponding to the second carrier (e.g., T _ offset2 in table 1). After the timing offset of the second carrier is obtained, a timing offset corresponding to the first carrier (e.g., T _ offset1 in table 1) may also be obtained, and the data transmission time of each data segment may be determined based on the scheduling delay, the timing offset of the first carrier, and the timing offset of the second carrier. In an exemplary manner, the first and second electrodes are,

if T _ offset1> -T _ offset2, the data transfer time T _1 of the first data segment is T _ start + T0+ T _ offset1 (for convenience of description, the "data transfer time of the first data segment" will be simply referred to as "first time", hereinafter), and the data transfer time T _2 of the second data segment is T _ start + T0+ T _ offset1+ T1+ T2 (for convenience of description, the "data transfer time of the second data segment" will be simply referred to as "second time", hereinafter); wherein T _ start is a start time, T0 is the scheduling delay, T1 is a carrier switching delay, and T2 is a transmission duration of the first data segment. The transmission duration T2 of the first data segment may include the cumulative duration of the first transmission and the retransmission of the first data segment, wherein the number of retransmissions may be preconfigured (e.g., the maximum number of uplink retransmissions may be configured as 128).

If T _ offset1< ═ T _ offset2, the first time T _1 is T _ start + T0+ T _ offset2, and the second time T _2 is T _ start + T0+ T _ offset2+ T1+ T2.

Referring to fig. 6, as shown in fig. 6, the satellite 200 transmits DCI to the terminal 100 through the PDCCH where the first beam is located, instructs that the transmission block scheduled this time is divided into two data segments (for example, a first data segment and a second data segment), and transmits the two data segments on a first carrier corresponding to the first beam and a second carrier corresponding to the second beam. After receiving the DCI transmitted by the satellite 200 completely, the terminal 100 determines a start time T _ start, calculates a timing offset T _ offset2 of the second carrier, and compares the timing offset T _ offset2 of the second carrier with the timing offset T _ offset1 of the first carrier. Assuming that T _ offset1> -T _ offset2, the terminal 100 determines that the first time T _1 is T _ start + T0+ T _ offset1, where T0 is the scheduling delay indicated in DCI. Next, assuming that the accumulated duration of transmitting (e.g., including first transmission and retransmission) the first data segment is T2, the terminal 100 may determine that the second time T _2 is T _ start + T0+ T _ offset1+ T1+ T2, where T1 is a carrier switching delay.

Alternatively, if T _ offset1< ═ T _ offset2, the first time T _1 is T _ start + T0+ T _ offset1, and the second time T _2 is T _ start + T0+ T _ offset2+ T1+ T2.

Referring to fig. 7, as shown in fig. 7, the satellite 200 transmits DCI to the terminal 100 through the PDCCH where the first beam is located, instructs that the transmission block scheduled this time is divided into two data segments (for example, a first data segment and a second data segment), and transmits the two data segments on a first carrier corresponding to the first beam and a second carrier corresponding to the second beam. After receiving the DCI transmitted by the satellite 200 completely, the terminal 100 determines a start time T _ start, calculates a timing offset T _ offset2 of the second carrier, and compares the timing offset T _ offset2 of the second carrier with the timing offset T _ offset1 of the first carrier. Assuming that T _ offset1< T _ offset2, the terminal 100 determines that the first time T _1 is T _ start + T0+ T _ offset1, where T0 is the scheduling delay indicated in the DCI. Next, assuming that the accumulated duration of transmitting (e.g., including first transmission and retransmission) the first data segment is T2, the terminal 100 may determine that the second time T _2 is T _ start + T0+ T _ offset2+ T1+ T2, where T1 is a carrier switching delay.

In step 305, the terminal 100 transmits data to the satellite 200 based on the data transmission time.

Specifically, the terminal 100 may transmit a first data segment to the satellite 200 using a first carrier based on the first time, and may retransmit the first data segment based on a preset number of retransmissions. Then, after the retransmission of the first data segment is completed, a second data segment may be transmitted to the satellite 200 using a second carrier based on the second time, and the second data segment may be retransmitted based on a preset number of retransmissions.

It should be noted that the foregoing embodiment only illustrates a scenario in which a transport block is divided into two parts, and does not constitute a limitation to the embodiment of the present application, and in some embodiments, the transport block may be divided into more blocks.

In the embodiment of the application, the network side indicates the terminal side to divide the transmission block into two parts, the two parts are respectively transmitted on two carriers, and each part of the transmission block corresponds to different transmission time delays when being transmitted, so that the time synchronization of the network side and the terminal side can be realized, the cross-carrier application can be fully utilized, and the data transmission efficiency can be improved.

Fig. 8 is a schematic flowchart of a data transmission method according to still another embodiment of the present application, including:

the satellite 200 transmits the timing offset configuration information, step 401.

In step 402, the terminal 100 receives and stores the timing offset configuration information transmitted from the satellite 200.

In step 403, the satellite 200 transmits scheduling information to the terminal 100 via the first beam instructing the terminal 100 to transmit a plurality of transport blocks on both beams.

Specifically, in order to improve the utilization efficiency between the beams, the satellite 200 may transmit the plurality of transport blocks scheduled this time on two beams respectively (for example, may transmit on a first beam and a second beam). In particular implementations, the satellite 200 may transmit scheduling information to the terminal 100, where the scheduling information may be carried by DCI or RAR Grant. The scheduling information may include a scheduling delay, an ID of the second carrier, and transport block identification information, where the transport block identification information is used to indicate a corresponding situation of a transport block and an uplink carrier. Table 4 is an example table of transport block identification information.

TABLE 4

Carrier ID	Transport block aggregation
		Uplink carrier
1	Transport block 1, transport block 3, transport block 5
		Uplink carrier 2	Transport block 2, transport block 4
…	…

As shown in table 4, the transport blocks 1, 3 and 5 may form a transport block set, and the transport block set may correspond to the uplink carrier 1, that is, the terminal 100 may transmit the transport blocks 1, 3 and 5 on the uplink carrier 1; while transport blocks 2 and 4 may constitute another transport block set, which may correspond to uplink carrier 2, i.e., terminal 100 may transmit transport blocks 2 and 4 on uplink carrier 2.

It is to be understood that table 4 above only illustrates a scenario of 5 transport blocks, and does not constitute a limitation to the embodiment of the present application, and in some embodiments, the terminal 100 may transmit more or less transport blocks based on the scheduling of the satellite 200 when transmitting. Illustratively, each transport block set may include one or more transport blocks.

In step 404, the terminal 100 receives the scheduling information transmitted from the satellite 200 and determines a data transmission time based on the scheduling information.

Specifically, since the satellite 200 transmits the DCI or the RAR Grant through the first beam, the terminal 100 may receive the DCI or the RAR Grant through the first carrier based on the mapping relationship between the uplink carrier and the beam. When receiving the DCI or RAR Grant transmitted by the satellite 200, the terminal 100 may acquire scheduling information (e.g., scheduling delay, ID of the second carrier, and transport block identifier information) in the DCI or RAR Grant.

Next, a timing offset corresponding to the second carrier (e.g., T _ offset2 in table 1) may be obtained by looking up in the timing offset configuration information based on the ID of the second carrier (e.g., uplink carrier 2 in table 4). After the timing offset of the second carrier is obtained, a timing offset (e.g., T _ offset1 in table 1) corresponding to the first carrier (e.g., uplink carrier 1 in table 4) may also be obtained, and the data transmission timings of the first transport block set (e.g., the transport block set including transport block 1, transport block 3, and transport block 5 in table 4) and the second transport block set (e.g., the transport block set including transport block 2 and transport block 4 in table 4) may be determined based on the scheduling delay, the timing offset of the first carrier, and the timing offset of the second carrier. In an exemplary manner, the first and second electrodes are,

if T _ offset1> -T _ offset2, the data transmission time T _3 of the first transport block set (e.g., the transport block set including transport block 1, transport block 3, and transport block 5 in table 4) is T _ start + T0+ T _ offset1 (for convenience of description, the "data transmission time of the first transport block set" is hereinafter simply referred to as "the third time"), and the data transmission time T _4 of the second transport block set (e.g., the transport block set including transport block 2 and transport block 4 in table 4) is T _ start + T0+ T _ offset1+ T1+ T2 (for convenience of description, the "data transmission time of the second transport block set" is hereinafter simply referred to as "the fourth time"); wherein T _ start is a start time, T0 is the scheduling delay, T1 is a carrier switching delay, and T2 is a transmission duration of a first transport block set, the transmission duration of the first transport block set may be determined by an accumulated transmission duration of all transport blocks in the first transport block set, and the transmission duration of each transport block is determined by a preset number of retransmissions of each transport block. For example, assuming that the first transport block set includes transport block 1, transport block 3, and transport block 5, if the transmission duration of transport block 1 is T21, the transmission duration of transport block 3 is T22, and the transmission duration of transport block 5 is T23, the transmission duration T2 of the first transport block set is T21+ T22+ T23.

If T _ offset1< ═ T _ offset2, the third time T _3 is T _ start + T0+ T _ offset2, and the fourth time T _4 is T _ start + T0+ T _ offset2+ T1+ T2.

Now, referring to fig. 9, as shown in fig. 9, the satellite 200 transmits DCI to the terminal 100 through the PDCCH where the first beam is located, and instructs two transport block sets (for example, the first transport block set and the second transport block set) of the current scheduling to transmit on the first carrier corresponding to the first beam and the second carrier corresponding to the second beam, respectively. After receiving the DCI transmitted by the satellite 200 completely, the terminal 100 determines a start time T _ start, calculates a timing offset T _ offset2 of the second carrier, and compares the timing offset T _ offset2 of the second carrier with the timing offset T _ offset1 of the first carrier. Assuming that T _ offset1> -T _ offset2, the terminal 100 determines that the third time T _3 is T _ start + T0+ T _ offset1, where T0 is the scheduling delay indicated in the DCI. Next, assuming that the accumulated time duration for transmitting the first transport block set is T2, the terminal 100 may determine that the fourth time T _4 is T _ start + T0+ T _ offset1+ T1+ T2, where T1 is a carrier switching time delay.

Alternatively, if T _ offset1< ═ T _ offset2, the third time T _3 is T _ start + T0+ T _ offset1, and the fourth time T _4 is T _ start + T0+ T _ offset2+ T1+ T2.

Now, referring to fig. 10, as shown in fig. 10, the satellite 200 transmits DCI to the terminal 100 through the PDCCH where the first beam is located, and instructs two transport block sets (for example, the first transport block and the second transport block) scheduled this time to transmit on the first carrier corresponding to the first beam and the second carrier corresponding to the second beam, respectively. After receiving the DCI transmitted by the satellite 200 completely, the terminal 100 determines a start time T _ start, calculates a timing offset T _ offset2 of the second carrier, and compares the timing offset T _ offset2 of the second carrier with the timing offset T _ offset1 of the first carrier. Assuming that T _ offset1< T _ offset2, the terminal 100 determines that the third time T _3 is T _ start + T0+ T _ offset1, where T0 is the scheduling delay indicated in the DCI. Next, assuming that the accumulated duration for transmitting the first transport block set is T2, the terminal 100 may determine that the fourth time T _4 is T _ start + T0+ T _ offset2+ T1+ T2, where T1 is a carrier switching delay.

In step 405, the terminal 100 transmits data to the satellite 200 based on the data transmission time.

Specifically, the terminal 100 may transmit the first set of transport blocks to the satellite 200 using the first carrier based on the third time instant. Next, after transmission of all transport blocks in the first set of transport blocks is completed, a second set of transport blocks may be transmitted to the satellite 200 using the second carrier based on the fourth time.

In the embodiment of the application, the network side indicates the terminal side to transmit the two transmission block sets on the two carriers respectively, and each transmission block set corresponds to different transmission delays when being transmitted, so that time synchronization of the network side and the terminal side can be realized, cross-carrier application can be fully utilized, and data transmission efficiency can be improved.
