Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular to a data transmission method and device, and a storage medium. Background Art

[0002] In the research of wireless communication technology, satellite communication is considered a key aspect of future wireless communication development. Satellite communication refers to communication conducted by ground-based radio communication equipment using satellites as relays. A satellite communication system consists of a satellite component and a ground component. Satellite communication features a wide communication range; communication is possible between any two points within the range of the satellite's radio waves; and it is not susceptible to land-based disasters (high reliability). As a supplement to current terrestrial cellular communication systems, satellite communication offers the following advantages: First, it can provide extended coverage. For areas where current cellular communication systems are inaccessible or costly to cover, such as oceans, deserts, and remote mountainous areas, satellite communication can provide a solution. Second, it can provide emergency communications. For example, in extreme situations such as earthquakes, when cellular communication infrastructure is unavailable, satellite communication can quickly establish a communication connection. Furthermore, it can provide industrial applications. For example, for latency-sensitive services over long distances, satellite communication can reduce transmission latency.

[0003] It can be foreseen that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the intelligent connection of all things.

[0004] In current terrestrial communication systems, data transmission is generally based on scheduling. This means that the base station uses scheduling instructions to instruct the terminal to transmit or receive data at the specified time-frequency resource locations. Alternatively, the base station can pre-configure the resources for the terminal to transmit or receive data, and the terminal transmits or receives data at the corresponding time-frequency resource locations based on the configuration information.

[0005] However, for some terminals, due to their capabilities, only half-duplex transmission is supported. That is, in a given time unit, either downlink data reception or uplink data transmission is performed, not simultaneous reception and transmission. However, in NTN (Non-terrestrial Network) scenarios, due to propagation delays, the satellite may not be able to accurately know the timing of the terminal's downlink and uplink. Therefore, it is possible that the terminal receives a schedule for downlink reception and uplink transmission, instructing the terminal to perform both uplink and downlink transmission simultaneously in at least one time unit.

This ensures the normal operation of terminal services in satellite communications.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0098] The following first introduces the data transmission solution provided by the present disclosure from the terminal side.

[0099] The present disclosure provides a data transmission method, referring to Figure 1 As shown, Figure 1 This is a flowchart of an uplink scheduling method according to one embodiment. The method can be used for terminals, including but not limited to terminals that support half-duplex. Half-duplex means that either uplink data is sent or downlink data is received in a time unit, and synchronous data transmission and reception are not supported. A half-duplex terminal can be an NB-IoT (Narrow Band Internet of Things) device. The method may include the following steps:

[0100] In step 101, in response to determining that there is an uplink and downlink transmission scheduling conflict in a target time unit, data transmission is performed in the target time unit.

[0101] The data transmission includes downlink data reception or uplink data transmission.

[0102] In the embodiment of the present disclosure, the target time unit is a time unit in which there is an uplink and downlink transmission scheduling conflict. The time unit may include but is not limited to a slot. The terminal either receives downlink data or sends uplink data in the target time unit.

[0103] In the above embodiment, the terminal receives downlink data or sends uplink data in the target time unit where there is an uplink and downlink transmission scheduling conflict, which can effectively solve the uplink and downlink transmission scheduling conflict problem in satellite communications.

[0104] In some optional embodiments, reference Figure 2 As shown, Figure 2 FIG. 1 is a flow chart of another uplink scheduling method according to an embodiment. The method may include the following steps:

[0105] In step 201, data transmission is performed in the target time unit based on an indication of the target transmission mode.

[0106] The data transmission includes downlink data reception or uplink data transmission.

[0107] In the disclosed embodiments, the target transmission mode is used to instruct a terminal to receive downlink data or transmit uplink data during a target time unit. In a target time unit where there is an uplink or downlink transmission scheduling conflict, if the target transmission mode indicates downlink data reception, the terminal receives downlink data; if the target transmission mode indicates uplink data transmission, the terminal transmits uplink data.

[0108] In the above embodiment, based on the indication of the target transmission mode, downlink data reception or uplink data transmission can be performed at the target time unit where there is an uplink and downlink transmission scheduling conflict, thereby solving the problem of uplink and downlink transmission scheduling conflict in satellite communications.

[0109] In some optional embodiments, the target transmission mode may be determined according to predefined settings, such as protocol agreements.

[0110] In the above embodiment, the terminal can determine the target transmission mode based on the predefined settings, so that in the target time unit where there is an uplink and downlink transmission scheduling conflict, the terminal can receive downlink data or send uplink data based on the indication of the target transmission mode, thereby solving the problem of uplink and downlink transmission scheduling conflict in satellite communications.

[0111] In some optional embodiments, the target transmission mode may be determined based on target signaling sent by the satellite. The target signaling includes, but is not limited to, higher-layer signaling or physical layer signaling sent by the satellite. The higher-layer signaling may include, but is not limited to, RRC (Radio Resource Control) signaling or MAC (Media Access Control Address) CE (Control Element) signaling.

[0112] In the above embodiment, the terminal can determine the target transmission mode based on the target signaling sent by the satellite, so that in the target time unit where there is an uplink and downlink transmission scheduling conflict, the terminal can receive downlink data or send uplink data based on the indication of the target transmission mode, thereby solving the problem of uplink and downlink transmission scheduling conflict in satellite communication.

[0113] In some optional embodiments, reference Figure 3 As shown, Figure 3 is based on Figure 1 The embodiment shown is a flowchart of another uplink scheduling method. After completing step 101, the method may further include the following steps:

[0114] In step 102, in response to receiving downlink data at the target time unit, target indication information is sent to the satellite.

[0115] In an embodiment of the present disclosure, if the terminal abandons uplink data transmission in a target time unit, the terminal may send a target indication message to the satellite, wherein the target indication message is used to indicate that the terminal does not transmit uplink data in the target time unit.

[0116] In step 103, a first resource for transmitting target uplink data allocated by the satellite to the terminal based on the target indication information is received.

[0117] In an embodiment of the present disclosure, after receiving the target indication information, the satellite can initiate uplink scheduling signaling as soon as possible, and transmit the first resource allocated for the terminal to the terminal via the uplink scheduling signaling. After receiving the scheduling signaling, the terminal can determine the first resource indicated by the scheduling signaling. The first resource is a resource used to transmit the target uplink data, including but not limited to time domain and frequency domain resources.

[0118] In one example, the target uplink data includes first uplink data not transmitted by the terminal in the target time unit, that is, the first resource allocated by the satellite to the terminal based on the target indication information can be used to transmit the first uplink data not transmitted in the target time unit.

[0119] In another example, the target uplink data includes uplink data obtained by merging the first uplink data and the second uplink data. The first uplink data refers to uplink data that is not transmitted in the target time unit where there is an uplink and downlink transmission scheduling conflict, and the second uplink data refers to uplink data that the terminal needs to transmit in the time unit included in the first resource. For example, the first uplink data includes data A, the second uplink data includes data B, and the target uplink data includes the uplink data obtained by merging data A and data B.

[0120] In step 104, target uplink data is transmitted to the satellite during the time unit included in the first resource.

[0121] In an embodiment of the present disclosure, the terminal may send target uplink data to the satellite during the time unit included in the first resource.

[0122] In the above embodiment, when the terminal receives downlink data in the target time unit, it can first send target indication information to the satellite, and inform the satellite through the target indication information that the terminal does not send uplink data in the target time unit, so that the satellite can allocate the first resource to the terminal as soon as possible, so that the terminal can send the target uplink data to be transmitted to the satellite in the time unit included in the first resource, further solving the purpose of how to transmit the target uplink data to the satellite when the uplink data is not sent in the target time unit, and ensuring the normal operation of the terminal business in the satellite communication scenario.

[0123] In some optional embodiments, when sending the target indication information to the satellite, the terminal may send the target indication information to the satellite via, but not limited to, a PRACH (Physical Random Access Channel).

[0124] In the above embodiment, the target indication information can be sent to the satellite via the PRACH, so that the satellite can allocate the first resource to the terminal as quickly as possible, which is simple to implement and has high availability.

[0125] In some optional embodiments, reference Figure 4 As shown, Figure 4 is based on Figure 3 The embodiment shown is a flowchart of another uplink scheduling method. When a first resource allocated by a satellite to a terminal through uplink scheduling signaling includes multiple time units, transmitting target uplink data to the satellite during the time units included in the first resource may include the following steps:

[0126] In step 301, at least one first time unit is determined from a plurality of time units included in the first resource based on a predefined manner.

[0127] In the embodiment of the present disclosure, the predefined manner includes but is not limited to predefined rules, such as selecting at least one first time unit that comes first in time sequence.

[0128] In step 302, the target uplink data is transmitted to the satellite during the at least one first time unit.

[0129] In the above embodiment, when the first resource allocated by the satellite includes multiple time units, the terminal can determine at least one first time unit, and thereby transmit the target uplink data to the satellite during the at least one first time unit. This ensures normal operation of terminal services in satellite communications.

[0130] In some optional embodiments, reference Figure 5 As shown, Figure 5 is based on Figure 1The embodiment shown is a flowchart of another uplink scheduling method. After completing step 101, the method may further include the following steps:

[0131] In step 102', in response to receiving downlink data in the target time unit, target indication information and target uplink data are transmitted to the satellite in the time unit included in the second resource for uplink data transmission pre-allocated by the satellite to the terminal.

[0132] In an embodiment of the present disclosure, the time unit included in the second resource is located after the target time unit, that is, the satellite has pre-allocated the second resource for uplink data transmission to the terminal. The terminal can directly transmit the target indication information and target uplink data to the satellite through the time unit included in the second resource based on determining that there is an uplink and downlink scheduling conflict in the target time unit and no uplink data is sent in the target time unit.

[0133] The target indication information is used to indicate that the terminal does not send uplink data in the target time unit.

[0134] In an example, the target uplink data includes first uplink data that is not transmitted by the terminal in the target time unit.

[0135] In another example, the target uplink data includes uplink data obtained by combining the first uplink data and second uplink data, wherein the second uplink data is uplink data that the terminal needs to transmit in the time unit included in the first resource.

[0136] In the above embodiment, the terminal may also transmit target indication information and target uplink data to the satellite in a time unit included in the second resource for uplink transmission pre-allocated by the satellite to the terminal, thereby ensuring normal terminal services in satellite communications.

[0137] In some optional embodiments, the second resource may include but is not limited to a resource for random access by the terminal.

[0138] In an embodiment of the present disclosure, a satellite pre-allocates random access resources for a terminal. These resources can be used by the terminal to initiate a random access message. The terminal can directly send target indication information and target uplink data to the satellite based on the time unit included in the random access resources. This allows the satellite to determine, based on the target indication information, that the target uplink data is the first uplink data that the terminal did not transmit during the target time unit in which an uplink or downlink scheduling conflict exists, or that the target uplink data is the uplink data obtained by combining the first uplink data with the second uplink data.

[0139] The second resource may include but is not limited to resources allocated by the satellite to the terminal for sending msg3 (message 3) or msgB (message B) during the random access process.

[0140] In the above embodiment, the terminal can send both the target indication information and the target uplink data to the satellite through the second resource pre-allocated to the terminal by the satellite, thereby ensuring normal operation of the terminal service in the satellite communication.

[0141] In some optional embodiments, if the second resource pre-allocated by the satellite to the terminal includes multiple time units, then referring to Figure 6 As shown, Figure 6 is based on Figure 5 The embodiment shown is a flowchart of another uplink scheduling method, in which a terminal transmits target indication information and target uplink data to the satellite during a time unit included in a second resource pre-allocated by the satellite for uplink data transmission. The method may include:

[0142] In step 401, at least one second time unit is determined from a plurality of time units included in the second resource based on a predefined manner.

[0143] In the embodiment of the present disclosure, the predefined manner includes but is not limited to predefined rules, such as selecting at least one second time unit that comes earlier in time sequence.

[0144] In step 402, the target indication information and the target uplink data are transmitted to the satellite during the at least one second time unit.

[0145] In the above embodiment, when the second resource includes multiple time units, the terminal can determine at least one second time unit, and transmit the target uplink data to the satellite during the at least one second time unit. In satellite communications, normal terminal services are ensured.

[0146] In some optional embodiments, if the terminal sends the target indication information and the target uplink data to the satellite in the time unit included in the second resource, and the target uplink data includes the uplink data obtained by combining the first uplink data and the second uplink data, then referring to Figure 7 As shown, Figure 7 is based on Figure 5 The embodiment shown is a flow chart of another uplink scheduling method, wherein the method further includes the following steps:

[0147] In step 103 ′, association information associated with the target uplink data is sent to the satellite.

[0148] In an embodiment of the present disclosure, the associated information includes but is not limited to at least one of the following: indication information for indicating that the target data packet corresponding to the target uplink data has been transmitted, transmission parameters of the target data packet, and identification information of the data packet corresponding to the first uplink data in the target time unit.

[0149] When the terminal uploads target uplink data based on the second resource pre-allocated by the satellite, and the target uplink data includes uplink data obtained by merging the first uplink data and the second uplink data, the terminal can also send an indication message to the satellite, informing the satellite through the indication message that the terminal has uploaded the target data packet corresponding to the target uplink data obtained by merging the first uplink data and the second uplink data.

[0150] Alternatively, the terminal may send transmission parameters of a target data packet to the satellite, including but not limited to the size of the target data packet. Alternatively, the terminal may send identification information of the data packet corresponding to the first uplink data in the target time unit to the satellite, informing the satellite of the identification information of the data packet that should have been uploaded in the target time unit.

[0151] In the above embodiment, when the terminal directly sends the target indication signal and target uplink data to the satellite through the second resource, and the target uplink data includes the uplink data obtained by merging the first uplink data and the second uplink data, the associated information can also be sent to the satellite to facilitate the satellite to determine the data information of the target uplink data and ensure the normal operation of the terminal business.

[0152] Next, the data transmission solution provided by the present disclosure will be introduced from the satellite side.

[0153] The present disclosure provides another data transmission method. Figure 8 As shown, Figure 8 FIG. 1 is a flow chart of an uplink scheduling method according to an embodiment, which can be used for a satellite. The method may include the following steps:

[0154] In step 501, in response to receiving target indication information sent by a terminal, a first resource for transmitting target uplink data is configured for the terminal.

[0155] The target indication information is used to indicate that the terminal does not send uplink data in a target time unit, and the target time unit is a time unit in which the terminal determines that there is an uplink and downlink transmission scheduling conflict.

[0156] After receiving the target indication information, the satellite can configure the first resource for transmitting the target uplink data for the terminal as soon as possible.

[0157] In step 502, the first resource is sent to the terminal.

[0162] In the above embodiment, after allocating the first resource to the terminal, the satellite can receive target uplink data uploaded by the terminal based on the time unit included in the first resource, thereby ensuring normal operation of the terminal service.

[0163] In some optional embodiments, the target uplink data may include first uplink data that is not transmitted by the terminal in the target time unit.

[0164] Alternatively, the target uplink data includes uplink data obtained by merging the first uplink data and second uplink data, wherein the second uplink data is uplink data that the terminal needs to transmit in the time unit included in the first resource.

[0165] In the above embodiment, the first resource allocated by the satellite to the terminal based on the target indication information can be used to transmit the first uplink data that the terminal did not transmit in the target time unit, or can also be used to transmit uplink data obtained by combining the first uplink data and the second uplink data, which has high availability.

[0166] The present disclosure provides another data transmission method. Figure 10 As shown, Figure 10 FIG. 1 is a flow chart of an uplink scheduling method according to an embodiment, which can be used for a satellite. The method may include the following steps:

[0167] In step 601, target indication information and target uplink data sent by a terminal in a time unit included in a second resource are received.

[0168] In an embodiment of the present disclosure, the second resource is a resource pre-allocated to the terminal for uplink transmission, and the time unit included in the second resource is located after the target time unit. The target indication information is used to indicate that the terminal does not transmit uplink data during the target time unit, and the target time unit is the time unit in which the terminal determines that there is an uplink and downlink transmission scheduling conflict. The satellite can directly receive the target indication information and target uplink data uploaded by the terminal via the time unit included in the second resource.

[0169] In the above embodiment, the satellite can directly receive the target indication information and target uplink data sent by the terminal through the pre-allocated second resource, effectively solving the problem of uplink and downlink transmission scheduling conflicts in satellite communications while ensuring the normal operation of terminal services.

[0170] In some optional embodiments, the second resource may include but is not limited to a resource for the terminal to perform random access. Further, the second resource may include but is not limited to a resource allocated by the satellite to the terminal to send msg3 (message 3) or msgB (message B) during the random access process.

[0171] In the above embodiment, the satellite can receive the target indication information and target uplink data transmitted by the terminal through the time unit included in the random access resource, which is simple to implement and has high availability.

[0172] In some optional embodiments, the target uplink data may include first uplink data that is not transmitted by the terminal in the target time unit.

[0173] Alternatively, the target uplink data includes uplink data obtained by merging the first uplink data and second uplink data, wherein the second uplink data is uplink data that the terminal needs to transmit in the time unit included in the first resource.

[0174] In the above embodiment, the satellite can receive first uplink data transmitted by the terminal via the pre-allocated second resource but not transmitted by the terminal in the target time unit. Alternatively, the satellite can receive uplink data obtained by combining the first uplink data and the second uplink data via the second resource, which has high availability.

[0175] In some optional embodiments, reference Figure 11 As shown, Figure 11 FIG. 5 is a flow chart of an uplink scheduling method according to an embodiment. The method may include the following steps:

[0176] In step 701, in response to determining that there is an uplink and downlink transmission scheduling conflict in a target time unit, the terminal performs data transmission in the target time unit based on an indication of a target transmission mode. The data transmission includes downlink data reception or uplink data transmission.

[0177] In step 702, in response to receiving downlink data at the target time unit, the terminal sends target indication information to the satellite.

[0178] The target indication information is used to indicate that the terminal does not send uplink data in the target time unit. Optionally, the terminal may send the target indication information to the satellite via a PRACH.

[0179] In step 703, in response to receiving the target indication information sent by the terminal, the satellite configures a first resource for transmitting target uplink data for the terminal.

[0180] In an example, the target uplink data includes first uplink data that is not transmitted by the terminal in the target time unit.

[0181] In another example, the target uplink data includes uplink data obtained by merging the first uplink data and second uplink data, wherein the second uplink data is uplink data that the terminal needs to transmit in the time unit included in the first resource.

[0182] In step 704, the satellite sends the first resource to the terminal.

[0183] Optionally, the satellite may send the first resource to the terminal through uplink scheduling signaling.

[0184] In step 705, the terminal transmits target uplink data to the satellite in the time unit included in the first resource.

[0185] Among them, if the first resource includes multiple time units, the terminal can determine at least one first time unit from the multiple time units included in the first resource based on a predefined method. Furthermore, the terminal transmits the target uplink data to the satellite in the at least one first time unit.

[0186] In the above embodiment, the problem of scheduling conflicts between uplink and downlink transmissions in satellite communications is effectively solved, while ensuring the normal operation of terminal services.

[0187] In some optional embodiments, reference Figure 12 As shown, Figure 12 FIG. 5 is a flow chart of an uplink scheduling method according to an embodiment. The method may include the following steps:

[0188] In step 801, in response to determining that there is an uplink and downlink transmission scheduling conflict in the target time unit, the terminal performs data transmission, i.e., receives downlink data or sends uplink data, in the target time unit based on an indication of the target transmission mode.

[0189] In step 802, in response to receiving downlink data in the target time unit, the terminal transmits target indication information and target uplink data to the satellite in the time unit included in the second resource for uplink data transmission pre-allocated by the satellite to the terminal.

[0190] In an embodiment of the present disclosure, the time unit included in the second resource is located after the target time unit, and the target indication information is used to indicate that the terminal does not send uplink data in the target time unit. Optionally, the second resource includes resources for random access by the terminal.

[0191] If the second resource includes multiple time units, the terminal may determine at least one second time unit from the multiple time units included in the second resource based on a predefined manner, and then transmit the target uplink data to the satellite in the at least one second time unit.

[0192] In an example, the target uplink data includes first uplink data that is not transmitted by the terminal in the target time unit.

[0193] In the above embodiment, the problem of scheduling conflicts between uplink and downlink transmissions in satellite communications is effectively solved, while ensuring the normal operation of terminal services.

[0194] In some optional embodiments, the target uplink data includes uplink data obtained by merging the first uplink data and the second uplink data, wherein the second uplink data is uplink data that the terminal needs to transmit in the time unit included in the first resource.

[0195] Accordingly, refer to Figure 13 As shown, Figure 13 is based on Figure 12 The embodiment shown is a flow chart of another uplink scheduling method, which may further include the following steps:

[0196] In step 803, association information associated with the target uplink data is sent to the satellite.

[0197] In an embodiment of the present disclosure, the associated information includes at least one of the following: indication information for indicating that the target data packet corresponding to the target uplink data has been transmitted, transmission parameters of the target data packet, and identification information of the data packet corresponding to the first uplink data on the target time unit.

[0198] In the above embodiment, the problem of scheduling conflicts between uplink and downlink transmissions in satellite communications is effectively solved, while ensuring the normal operation of terminal services.

[0199] In some optional embodiments, upon determining that a scheduling conflict for uplink and downlink transmissions may exist in a target time unit, the satellite may send an indication message to the terminal. The indication message instructs the terminal to receive downlink data or transmit uplink data when the scheduling conflict for uplink and downlink transmissions exists in the target time unit. The terminal may directly receive downlink data or transmit uplink data based on the indication message sent by the satellite.

[0200] Optionally, the indication information may include but is not limited to SFI (slot Format Indicator) information.

[0201] In an example, if the indication information sent by the satellite indicates that the transmission mode of the terminal on at least one downlink bandwidth portion is a specified transmission mode, the terminal can send uplink data in the target time unit and give up receiving downlink data.

[0202] If the second target indication information is used to indicate that the transmission mode of the terminal on at least one uplink bandwidth part is a designated transmission mode, the terminal may receive downlink data in the target time unit and give up sending uplink data.

[0203] In an example, the designated transmission mode may be a preset transmission mode on the target transmission unit. For example, the designated transmission mode may be represented by “F”.

[0204] In the above embodiment, the terminal transmits uplink data during a target time unit based on the instruction information sent by the satellite, i.e., does not receive downlink data. Alternatively, the terminal can receive downlink data during a target time unit based on the instruction information sent by the satellite, i.e., does not transmit uplink data. This also effectively resolves the issue of uplink and downlink transmission scheduling conflicts in satellite communications.
