Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication technology, and in particular, to a method for transmitting uplink data and an apparatus thereof. BACKGROUND

[0002] Generally, when a terminal device performs uplink transmission in an unlicensed band, the terminal device needs to perform listen before talk (LBT) before starting uplink transmission, that is, the terminal device needs to listen to the unlicensed band first, and when LBT is successful, the terminal device can start to occupy the unlicensed band to perform uplink transmission. If LBT is not successful, the terminal device cannot occupy the unlicensed band to perform uplink transmission.

[0003] When a service with a relatively high latency requirement, such as an ultra reliable and low latency communication (URLLC) service, is transmitted in an unlicensed band, the LBT can fail, and thus the latency of the URLLC service transmission cannot be guaranteed. How to reduce the latency of service transmission in an unlicensed band has become a problem to be solved. SUMMARY

[0108] For ease of understanding, first introduce the terms involved in the present disclosure.

[0109] 1. Listen before talk (LBT)

[0110] LBT is a channel access mechanism. Generally, the availability of the channel on the unlicensed spectrum cannot be guaranteed at all times, so before transmitting data on the unlicensed spectrum, LBT needs to be performed, that is, the channel needs to be listened to and clear channel assessment (CCA) needs to be performed, and data transmission is performed only when it is ensured that the channel is idle.

[0111] 2, physical uplink shared channel (PUSCH)

[0112] Generally, the PUSCH can be used to carry data from the uplink shared channel (UL-SCH).

[0113] 3, repetition type

[0114] When the repetition type of the PUSCH is A, the specific transmission starting position can be indicated by indicating the consecutive transmission symbol L and the starting symbol position S. In the PUSCH repetition type A, each repetition is located on adjacent slots, and the position of the symbol occupied on each slot is the same.

[0115] When the repetition type of the PUSCH is B, it is a back-to-back repetition transmission, that is, the front and rear PUSCHs are adjacent in the time domain, so that each repetition can be transmitted as soon as possible to achieve the purpose of reducing the delay.

[0116] In order to better understand the method for transmitting uplink data disclosed in the embodiments of the present disclosure, first, the communication system to which the embodiments of the present disclosure are applicable will be described.

[0121] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0122] The uplink data transmission method and device provided by the present disclosure will be described in detail below in combination with the accompanying drawings.

[0123] Please refer to Figure 2 , Figure 2 is a flowchart of an uplink data transmission method provided by the embodiments of the present disclosure, which is configured to be executed by a terminal device. As Figure 2 shown, the method can include but is not limited to the following steps:

[0124] Step 21, determining a plurality of listen before talk (LBT) detection positions corresponding to a specified physical uplink shared channel (PUSCH) scheduled on an unlicensed spectrum.

[0125] Generally, when a terminal device transmits services on an unlicensed frequency spectrum, it needs to perform LBT detection first. When LBT is successful, the terminal device can start occupying the unlicensed frequency spectrum for uplink transmission. If LBT is not successful, the terminal device cannot occupy the unlicensed frequency spectrum for uplink transmission.

[0126] It can be understood that when the terminal device detects that the interference on the unlicensed frequency spectrum, such as noise, signal-to-noise ratio, is lower than the threshold value, it can be considered that LBT is successful.

[0127] The threshold value can be a value agreed by a protocol, or a value configured by a network device for the terminal device, and the like, which is not limited in the present disclosure.

[0128] In the present disclosure, when transmitting services on an unlicensed frequency spectrum, multiple LBT detection positions are set for a specified PUSCH, and listening is performed at each LBT detection position to increase the probability of occupying the channel, thereby minimizing the latency of service transmission.

[0129] Optionally, when at least two repetitions of any PUSCH are connected at the beginning and end in the time domain, the terminal device can occupy the unlicensed frequency spectrum and continuously transmit the at least two repetitions when the listening at the starting position of the first repetition of the at least two repetitions is successful. Thus, in the present disclosure, multiple LBTs can be set for the PUSCH corresponding to the at least two repetitions connected at the beginning and end in the time domain, thereby improving the probability of occupying the channel by the PUSCH.

[0130] Optionally, when the repetition type of any PUSCH is B, it can be determined that any PUSCH is a specified PUSCH.

[0131] It can be understood that the two repetitions of the PUSCH with repetition type B are connected at the beginning and end in the time domain, and thus the PUSCH with repetition type B is determined as a specified PUSCH, which can be transmitted in a smaller unit of time resources, thereby increasing the probability of occupying the channel by the PUSCH and increasing the probability of successful transmission, thereby achieving the purpose of reducing latency.

[0132] Optionally, when the repetition type of any PUSCH is A, and the ending position of the first repetition of the two adjacent repetitions of any PUSCH is the starting position of the second repetition, it can be determined that any PUSCH is a specified PUSCH.

[0133] It can be understood that when the PUSCH is of the repetition type A, if the length of the continuous symbols corresponding to one repetition is 14, the repetition is adjacent to the next adjacent repetition in the time domain, so that the PUSCH is determined as the specified PUSCH, the probability of occupying the channel of the PUSCH can be increased, so that the probability of successful transmission is increased, and the purpose of reducing the delay is achieved.

[0134] Optionally, after the terminal device determines the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed frequency spectrum, the terminal device can perform LBT monitoring at each LBT detection position. If the LBT fails, communication transmission cannot be performed, and LBT detection can be continued at other LBT detection positions thereafter, so that the probability of occupying the channel can be increased, the delay of service transmission is reduced, the utilization rate of uplink resources is improved, and the performance of the system is further improved.

[0135] It can be understood that when the terminal device performs PUSCH repetition transmission on the unlicensed frequency spectrum, whether the PUSCH repetition transmission is ended can have multiple cases.

[0136] For example, when the terminal device performs PUSCH repetition transmission on the unlicensed frequency spectrum, the channel occupancy time (COT) cannot be exceeded. If the COT is exceeded, the PUSCH repetition transmission needs to be terminated. Alternatively, the protocol stipulates that when invalid symbols are encountered, the PUSCH repetition cannot be transmitted on the invalid symbols. Therefore, after the LBT succeeds, the terminal device can also not completely perform the transmission of all PUSCH repetitions after the LBT detection position.

[0137] It can be understood that when the PUSCH scheduled on the unlicensed frequency spectrum is a non-specified PUSCH, the unlicensed frequency spectrum can be monitored only before the start of the first PUSCH repetition according to the related art. If the LBT fails, the multiple repetitions included in the PUSCH cannot be transmitted.

[0138] In the embodiments of the present disclosure, the terminal device can first determine the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed frequency spectrum, and then perform LBT monitoring at the multiple LBT detection positions. In this way, by setting multiple possible LBT detection positions, the unlicensed frequency spectrum is monitored, so that the probability of occupying the channel is increased, and the delay of service transmission is reduced.

[0139] Please refer to Figure 3 , Figure 3 is a flowchart of an uplink data transmission method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. As shown in Figure 3 , the method can include but is not limited to the following steps:

[0140] Step 31, determining the starting position of each repetition of the specified PUSCH scheduled on the unlicensed spectrum as an LBT detection position.

[0141] Optionally, in response to the repetition type of any PUSCH being B, the terminal device determines the any PUSCH as the specified PUSCH; or in response to the repetition type of any PUSCH being A and the ending position of the first repetition of the two adjacent repetitions of the any PUSCH being the starting position of the second repetition, the terminal device determines the any PUSCH as the specified PUSCH.

[0142] It should be noted that the specific content and implementation of the specified PUSCH can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0143] For example, when the specified PUSCH is a PUSCH with repetition type B, the number of repetitions of the PUSCH repetition is 4, and the terminal device can determine the starting position of each repetition of the PUSCH as an LBT detection position, so that there are a total of 4 LBT detection positions.

[0144] It should be noted that the above example is only illustrative and cannot be regarded as a limitation on the number of repetitions of the PUSCH repetition, the LBT detection position, etc. in the embodiments of the present disclosure

[0145] Step 32, performing LBT listening on the unlicensed spectrum at each LBT detection position.

[0146] It can be understood that after the terminal device determines the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed spectrum, LBT listening can be performed at each LBT detection position, so as to increase the probability of channel occupation and reduce the delay of service transmission.

[0147] Step 33, in response to LBT success at any LBT detection position, occupying the unlicensed spectrum to transmit each repetition of the specified PUSCH after the any LBT detection position.

[0148] For example, the terminal device determines that there are 4 LBT detection positions, which are 0, 1, 2 and 3 respectively, and which are located at the time domain starting positions of PUSCH repetition 0, PUSCH repetition 1, PUSCH repetition 2 and PUSCH repetition 3 respectively.

[0149] Therefore, the terminal device can first listen to the unlicensed spectrum at the LBT detection position 0, and if the LBT fails, the terminal device can listen to the unlicensed spectrum again at the LBT detection position 1. If the terminal device succeeds in the LBT at the LBT detection position 1, the terminal device can occupy the unlicensed spectrum to transmit the specified PUSCH repetitions after the LBT detection position 1, i.e., to transmit PUSCH repetition 1, PUSCH repetition 2 and PUSCH repetition 3.

[0150] If the LBT fails at the LBT detection position 1, the terminal device can listen to the unlicensed spectrum again at the LBT detection position 2. If the terminal device succeeds in the LBT at the LBT detection position 2, the terminal device can occupy the unlicensed spectrum to transmit PUSCH repetition 2 and PUSCH repetition 3 after the LBT detection position 2.

[0151] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the manner of occupying the unlicensed spectrum to transmit the repetitions in the embodiments of the present disclosure.

[0152] It can be understood that when the PUSCH scheduled on the unlicensed spectrum is a non-specified PUSCH, the terminal device can only listen to the unlicensed spectrum before the start of the first PUSCH repetition according to the related art. If the LBT fails, the multiple repetitions contained in the PUSCH cannot be transmitted.

[0153] It should be noted that whether the transmission of the PUSCH repetition ends or not when the terminal device transmits the repetitions of the specified PUSCH after the LBT detection position on the unlicensed spectrum after the LBT succeeds can be referred to the description of other embodiments of the present disclosure, which will not be described here.

[0154] In the embodiment of the present disclosure, the terminal device can first determine the starting position of each repetition of the specified PUSCH scheduled on the unlicensed spectrum as an LBT detection position, and then can perform listening on the unlicensed spectrum at each LBT detection position. When LBT succeeds at any LBT detection position, the terminal device occupies the unlicensed spectrum to transmit the repetitions of the specified PUSCH after the LBT detection position. In this way, by setting multiple possible LBT detection positions to perform listening on the unlicensed spectrum, the probability of channel occupation is increased, and the delay of service transmission is reduced.

[0155] Please refer to Figure 4 , Figure 4 is a flowchart of an uplink data transmission method provided by an embodiment of the present disclosure, and the method is configured to be executed by a terminal device. As shown in Figure 4 , the method can include but is not limited to the following steps:

[0156] Step 41, determining the starting position of a specified repetition of a specified PUSCH scheduled on the unlicensed spectrum as an LBT detection position.

[0157] Optionally, in response to the repetition type of any PUSCH being B, the terminal device determines the any PUSCH as the specified PUSCH; or in response to the repetition type of any PUSCH being A and the ending position of the first repetition of the two adjacent repetitions of the any PUSCH being the starting position of the second repetition, the terminal device determines the any PUSCH as the specified PUSCH.

[0158] It should be noted that the specific content and implementation of the specified PUSCH can refer to the description of other embodiments of the present disclosure, and will not be repeated here.

[0159] Optionally, the specified repetition can be that the redundancy version (RV) corresponding to the repetition is an RV that can be self-decoded by the terminal device.

[0160] For example, when the specified PUSCH is a PUSCH with repetition type B, the number of repetitions of the PUSCH repetition is 4, and the RVs of the 4 repetitions are 0, 2, 3, and 1 respectively. Among them, the RVs that can be self-decoded by the terminal device are RV0 and RV3 respectively, and RV0 and RV3 are the specified RVs. Therefore, the terminal device can determine the time domain starting positions of the repetitions corresponding to RV0 and RV3 respectively, i.e., the time domain starting positions of PUSCH repetition 0 and PUSCH repetition 2 respectively, as the LBT detection positions.

[0161] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the determination of the LBT detection position and the like in the embodiments of the present disclosure.

[0162] Optionally, the terminal device can also determine the specified repetition from the multiple repetitions according to the indication of the network device. The present disclosure does not limit this.

[0163] Step 42: performing LBT listening at each LBT detection position.

[0164] It can be understood that after the terminal device determines the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed frequency spectrum, LBT listening can be performed at each LBT detection position, so as to increase the probability of channel occupation and reduce the delay of service transmission.

[0165] Step 43: in response to LBT success at any LBT detection position, occupying the unlicensed frequency spectrum to transmit each repetition of the specified PUSCH after the LBT detection position.

[0166] For example, the number of repetitions of the specified PUSCH repetition is 4, and the RVs of the 4 repetitions are 0, 2, 3, and 1 respectively. Among them, the RVs that can be self-decoded by the terminal device are RV0 and RV3 respectively, and RV0 and RV3 are the specified RVs. Therefore, the terminal device can determine the time domain starting positions of the repetitions corresponding to RV0 and RV3 respectively, i.e., the time domain starting positions of repetition 0 and repetition 2 respectively, as the LBT detection positions: LBT detection position 0 and LBT detection position 1.

[0167] Therefore, the terminal device can first listen to the unlicensed spectrum at the LBT detection position 0, and if the LBT fails, the terminal device can listen to the unlicensed spectrum again at the LBT detection position 1. If the LBT succeeds at the LBT detection position 1, the terminal device can occupy the unlicensed spectrum to transmit the specified PUSCH repetitions after the LBT detection position 1, i.e., the PUSCH repetition 2 and the PUSCH repetition 3.

[0168] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the manner of occupying the unlicensed spectrum to transmit the repetitions in the embodiments of the present disclosure.

[0169] It can be understood that when the PUSCH scheduled on the unlicensed spectrum is a non-specified PUSCH, the unlicensed spectrum can be listened to only before the start of the first PUSCH repetition according to the related art. If the LBT fails, the multiple repetitions included in the PUSCH cannot be transmitted.

[0170] It should be noted that whether the transmission of the PUSCH repetition ends when the terminal device transmits the repetitions of the specified PUSCH after the LBT detection position on the unlicensed spectrum after the LBT succeeds can be referred to the description of other embodiments of the present disclosure, and will not be described here.

[0171] In the embodiments of the present disclosure, the terminal device can first determine the start position of the specified repetition of the specified PUSCH scheduled on the unlicensed spectrum as the LBT detection position, and then listen to the unlicensed spectrum at each LBT detection position. When the LBT succeeds at any LBT detection position, the unlicensed spectrum is occupied to transmit the repetitions of the specified PUSCH after any LBT detection position. Therefore, by setting multiple possible LBT detection positions to listen to the unlicensed spectrum, the probability of channel occupation is increased, and the delay of service transmission is reduced.

[0172] Please refer to Figure 5 , Figure 5 is a flowchart of an uplink data transmission method provided by the embodiments of the present disclosure, and the method is configured to be executed by a terminal device. As shown in Figure 5 , the method can include but is not limited to the following steps:

[0173] Step 51, according to the first indication information, determining multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed spectrum.

[0174] It can be understood that the first indication information can be indication information sent by the network device to the terminal device, and the first indication information can indicate the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed frequency spectrum.

[0175] Therefore, the terminal device can first receive the first indication information, and then determine the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed frequency spectrum according to the indication of the first indication information.

[0176] Optionally, in response to the repetition type of any PUSCH being B, it is determined that the any PUSCH is the specified PUSCH; or in response to the repetition type of any PUSCH being A and the end position of the first repetition of the two adjacent repetitions of the any PUSCH being the start position of the second repetition, it is determined that the any PUSCH is the specified PUSCH.

[0177] It should be noted that the specific content and implementation manner of the specified PUSCH can refer to the description of other embodiments of the present disclosure, and will not be described here.

[0178] For example, the first indication information indicates that the start position of each repetition of the specified PUSCH is the LBT detection position. Therefore, after the terminal device determines that the PUSCH with the repetition type B is the specified PUSCH and the number of repetitions of the PUSCH repetition is 4, the terminal device can determine, according to the first indication information, that the start position of each repetition of the PUSCH is the LBT detection position, and thus it can be determined that there are four LBT detection positions.

[0179] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the first indication information, the LBT detection position and the like in the embodiments of the present disclosure

[0180] Optionally, the terminal device can also determine the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed frequency spectrum according to a protocol agreement.

[0181] For example, the protocol stipulates that the starting position of each repetition of the designated PUSCH is the LBT detection position. Thus, after the terminal device determines that the PUSCH with the repetition type B is the designated PUSCH and the number of repetitions of the PUSCH repetition is 4, the terminal device can determine, according to the protocol stipulation, that the starting position of each repetition of the PUSCH with the repetition type B is the LBT detection position, and thus can determine that there are 4 LBT detection positions.

[0182] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the first indication information, the LBT detection position, and the like in the embodiments of the present disclosure.

[0183] Step 52: performing listening on the unlicensed frequency spectrum at each LBT detection position.

[0184] Step 53: in response to LBT success at any LBT detection position, occupying the unlicensed frequency spectrum to perform transmission of each repetition of the designated PUSCH after the LBT detection position.

[0185] It should be noted that the specific content and implementation manner of steps 52 and 53 can be referred to the description of other embodiments of the present disclosure, which will not be described here.

[0186] It can be understood that when the PUSCH scheduled on the unlicensed frequency spectrum is the non-designated PUSCH, the terminal device can perform listening on the unlicensed frequency spectrum only before the start of the first PUSCH repetition according to the related art. If LBT fails, none of the repetitions included in the PUSCH can be transmitted.

[0187] It should be noted that whether the transmission of the PUSCH repetition ends after the terminal device performs transmission of each repetition of the designated PUSCH after the LBT detection position on the unlicensed frequency spectrum after LBT success can be referred to the description of other embodiments of the present disclosure, which will not be described here.

[0188] In the embodiments of the present disclosure, the terminal device can determine, according to the first indication information, the plurality of LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed frequency spectrum, and then perform listening on the unlicensed frequency spectrum at each LBT detection position. When LBT success at any LBT detection position, the terminal device occupies the unlicensed frequency spectrum to perform transmission of each repetition of the designated PUSCH after the LBT detection position. Thus, by setting a plurality of possible LBT detection positions to perform listening on the unlicensed frequency spectrum, the probability of channel occupation is increased and the delay of service transmission is reduced.

[0189] Please refer to Figure 6 , Figure 6 is a flowchart of an uplink data transmission method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. As shown in Figure 6 , the method can include but is not limited to the following steps:

[0190] Step 61, determining the priority of the specified PUSCH scheduled on the unlicensed spectrum according to the second indication information.

[0191] Optionally, in response to the repetition type of any PUSCH being B, it is determined that the any PUSCH is the specified PUSCH; or in response to the repetition type of any PUSCH being A and the end position of the first repetition of the two adjacent repetitions of the any PUSCH being the start position of the second repetition, it is determined that the any PUSCH is the specified PUSCH.

[0192] It should be noted that the specific content and implementation of the specified PUSCH can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0193] It can be understood that the second indication information can be indication information sent by a network device to a terminal device, which can indicate the priority of the specified PUSCH scheduled on the unlicensed spectrum.

[0194] Therefore, the terminal device can first receive the second indication information, and then determine the priority of the specified PUSCH scheduled on the unlicensed spectrum according to the indication of the second indication information.

[0195] Optionally, the second indication information can be downlink control information (DCI) or other information, etc., which is not limited by the present disclosure.

[0196] Optionally, the terminal device can determine the priority of the scheduled PUSCH according to the value of the information field (priority indicator) in the DCI for indicating the priority of the scheduled PUSCH.

[0197] For example, when the priority indicator has 1 bit to indicate the priority, it can indicate 2 kinds of priorities, high and low.

[0198] Or, when the priority indicator has multiple bits, multiple priorities can be indicated. For example, when the priority indicator has 2 bits, multiple priorities such as high, higher, low, and lowest can be indicated.

[0199] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the priority of the specified PUSCH in the embodiments of the present disclosure.

[0200] In step 62, in response to the priority corresponding to the specified PUSCH being the specified priority, the multiple LBT detection positions corresponding to the specified PUSCH are determined.

[0201] Optionally, the specified priority can be agreed upon by a protocol or configured by a network device, and the present disclosure does not limit this.

[0202] For example, when the priority indicator has only 1 bit, 2 priorities such as high and low can be indicated, and the specified priority is high priority. Therefore, when the terminal device determines that the priority of the specified PUSCH is high priority according to the indication of the DCI, the multiple LBT detection positions corresponding to the specified PUSCH can be further determined.

[0203] Or, when the priority indicator has multiple bits, the specified priority can include one priority or multiple priorities, such as high priority, higher priority, and the like. Therefore, when the terminal device determines that the priority of the specified PUSCH is the specified priority according to the indication of the DCI, the multiple LBT detection positions corresponding to the specified PUSCH can be further determined.

[0204] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the priority of the specified PUSCH in the embodiments of the present disclosure.

[0205] It should be noted that the specific content and implementation of determining the multiple LBT detection positions corresponding to the specified PUSCH can refer to the description of other embodiments of the present disclosure, and will not be repeated here.

[0206] It can be understood that when the priority corresponding to the specified PUSCH is not the specified priority, the multiple LBT detection positions corresponding thereto do not need to be further determined, and only the unlicensed spectrum can be monitored before the first PUSCH repetition starts according to the related art. If the LBT fails, the multiple repetitions contained in the PUSCH cannot be transmitted.

[0207] Or, when the PUSCH scheduled on the unlicensed spectrum is the non-designated PUSCH, the unlicensed spectrum can be monitored only before the start of the first PUSCH repetition according to the related art. If the LBT fails, none of the repetitions contained in the PUSCH can be transmitted.

[0208] Step 63, monitoring the unlicensed spectrum at each LBT detection position.

[0209] Step 64, in response to the LBT success at any LBT detection position, occupying the unlicensed spectrum to transmit each repetition of the designated PUSCH after the LBT detection position.

[0210] It should be noted that the specific content and specific implementation mode of steps 63 and 64 can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0211] It should be noted that whether the transmission of the PUSCH repetition ends when the terminal device transmits each repetition of the designated PUSCH after the LBT detection position on the unlicensed spectrum after the LBT success can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0212] In the embodiments of the present disclosure, the terminal device can first determine the priority of the designated PUSCH scheduled on the unlicensed spectrum according to the second indication information, when the priority corresponding to the designated PUSCH is the designated priority, determine the multiple LBT detection positions corresponding to the designated PUSCH, and then monitor the unlicensed spectrum at each LBT detection position, when the LBT is successful at any LBT detection position, the unlicensed spectrum can be occupied to transmit each repetition of the designated PUSCH after the LBT detection position. Therefore, by setting multiple possible LBT detection positions to monitor the unlicensed spectrum, the probability of channel occupation is increased, and the delay of service transmission is reduced.

[0213] Please refer to Figure 7 , Figure 7 is a flow diagram of an uplink data transmission method provided by the embodiments of the present disclosure, and the method is configured to be executed by a network device. As shown in Figure 7 , the method can include but is not limited to the following steps:

[0214] Step 71, determining multiple listen before talk (LBT) detection positions corresponding to a designated physical uplink shared channel (PUSCH) scheduled on an unlicensed spectrum.

[0215] Generally, when a terminal device transmits services on an unlicensed frequency spectrum, the terminal device needs to perform LBT detection first. When the LBT is successful, the terminal device can start to occupy the unlicensed frequency spectrum to transmit services, and accordingly, the network device can receive service data transmitted by the terminal device.

[0216] It can be understood that when the terminal device determines that the interference, such as noise, signal-to-noise ratio, etc., on the unlicensed frequency spectrum is lower than a threshold value, it can be considered that the LBT is successful, that is, at this time, the network device can receive service data transmitted by the terminal device on the unlicensed frequency spectrum.

[0217] The threshold value can be a value agreed by a protocol, or a value configured by the network device, etc., and the present disclosure does not limit this.

[0218] In the present disclosure, when transmitting services on an unlicensed frequency spectrum, the terminal device sets multiple LBT detection positions for a specified PUSCH to increase the probability of occupying the channel, so as to reduce the latency of service transmission as much as possible, and accordingly, the network device can determine the multiple LBT detection positions to receive data transmitted by the terminal device.

[0219] Optionally, when the repetition type of any PUSCH is B, it can be determined that any PUSCH is the specified PUSCH.

[0220] Optionally, when the repetition type of any PUSCH is A, and the end position of the first repetition of the two adjacent repetitions of any PUSCH is the start position of the second repetition, it can be determined that any PUSCH is the specified PUSCH.

[0221] It should be noted that the specific content and implementation of the specified PUSCH described above can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0222] Step 72, receiving each repetition of the specified PUSCH at the multiple LBT detection positions.

[0223] After the network device determines the multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed frequency spectrum, it can receive each repetition of the specified PUSCH at each LBT detection position.

[0224] It can be understood that if the terminal device fails in LBT, the network device cannot receive each repetition of the specified PUSCH, and can continue to receive the repetition at other LBT detection positions thereafter.

[0225] It can be understood that when the PUSCH scheduled on the unlicensed spectrum is the non-designated PUSCH, the network device can receive each repetition of the designated PUSCH from the LBT detection position according to the related technology.

[0226] In the embodiments of the present disclosure, the network device can first determine a plurality of LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum, and then receive each repetition of the designated PUSCH at the plurality of LBT detection positions. In this way, by receiving each repetition of the designated PUSCH at a plurality of possible LBT detection positions, the probability of channel occupation is increased, and the delay of service transmission is reduced.

[0227] Please refer to Figure 8 , Figure 8 is a flowchart of an uplink data transmission method provided by an embodiment of the present disclosure, and the method is configured to be executed by a network device. As shown in Figure 8 , the method can include but is not limited to the following steps:

[0228] Step 81, determining the starting position of the designated repetition of the designated PUSCH as an LBT detection position.

[0229] Optionally, in response to the repetition type of any PUSCH being B, the any PUSCH is determined as the designated PUSCH; or in response to the repetition type of any PUSCH being A and the ending position of the first repetition of the two adjacent repetitions of the any PUSCH being the starting position of the second repetition, the any PUSCH is determined as the designated PUSCH.

[0230] It should be noted that the specific content and implementation manner of the designated PUSCH can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0231] Optionally, the redundancy version RV corresponding to the designated repetition is an RV that can be self-decoded by the terminal device.

[0232] For example, when the specified PUSCH is a PUSCH with repetition type B, the number of repetitions of this PUSCH is 4, specifically 0, 1, 2, and 3, and the RVs of the 4 repetitions are 0, 2, 3, and 1, respectively. Among them, the RVs that the terminal device can self-decode are RV0 and RV3, so RV0 and RV3 are the specified RVs. Thus, the network device can determine the time-domain start positions of the repetitions corresponding to RV0 and RV3, i.e., PUSCH repetition 0 and PUSCH repetition 2, as the LBT detection positions.

[0233] It should be noted that the above examples are merely illustrative and should not be construed as limiting the determination of LBT detection locations, etc., in the embodiments of this disclosure.

[0234] Optionally, the network device can also define the starting position of each repetition of a specified PUSCH as an LBT detection position.

[0235] It should be noted that the specific content and implementation method of determining the LBT detection position based on the starting position of each repetition of the specified PUSCH can be found in the descriptions of other embodiments of this disclosure, and will not be repeated here.

[0236] Step 82: Send first indication information, wherein the first indication information is used to indicate to the terminal device the multiple LBT detection locations corresponding to the specified PUSCH scheduled on the unlicensed spectrum.

[0237] It should be noted that the operations performed by the terminal device according to the first instruction information and the corresponding effects can be referred to the descriptions of other embodiments of this disclosure, and will not be repeated here.

[0238] Optionally, the network device can also determine multiple LBT detection locations corresponding to a specified PUSCH scheduled on unlicensed spectrum, according to the protocol agreement.

[0239] It should be noted that the specific details and implementation methods of determining the multiple LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum according to the above-mentioned agreement can be referred to the descriptions of other embodiments of this disclosure, and will not be repeated here.

[0240] Step 83: At multiple LBT detection locations, receive each repetition of the specified PUSCH.

[0241] It should be noted that the specific content and implementation method of step 83 can be referred to the descriptions of other embodiments of this disclosure, and will not be repeated here.

[0242] It can be understood that when the PUSCH scheduled on the unlicensed spectrum is the non-designated PUSCH, the network device can receive each repetition of the designated PUSCH starting from the LBT detection position according to the related art.

[0243] In the embodiments of the present disclosure, the network device can determine the starting position of the designated repetition of the designated PUSCH as an LBT detection position, and then send first indication information, wherein the first indication information is used to indicate the plurality of LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum to the terminal device, and then receive each repetition of the designated PUSCH at the plurality of LBT detection positions. In this way, by receiving each repetition of the designated PUSCH at the plurality of possible LBT detection positions, the probability of channel occupation is increased, and the delay of service transmission is reduced.

[0244] Please refer to Figure 9 , Figure 9 is a flowchart of an uplink data transmission method provided by the embodiments of the present disclosure, and the method is configured to be executed by a network device. As shown in Figure 9 , the method can include but is not limited to the following steps:

[0245] Step 91, sending second indication information, wherein the second indication information is used to indicate the priority of the designated PUSCH to the terminal device.

[0246] Optionally, in response to the repetition type of any PUSCH being B, it is determined that the any PUSCH is the designated PUSCH; or in response to the repetition type of any PUSCH being A and the ending position of the first repetition of any two adjacent repetitions of the PUSCH being the starting position of the second repetition, it is determined that the any PUSCH is the designated PUSCH.

[0247] It should be noted that the specific content and implementation of the designated PUSCH can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0248] Optionally, the second indication information can be DCI or other information, etc., which is not limited in the present disclosure.

[0249] Optionally, the network device can assign a priority indicator in the DCI to indicate the priority of the scheduled PUSCH according to the priority of the scheduled PUSCH, so that the terminal device determines the priority of the scheduled PUSCH according to the received DCI information.

[0250] For example, the priority of the scheduled PUSCH has two priorities, high and low, which can be indicated by one bit in the priority indicator.

[0251] Or, the scheduled PUSCH has multiple priorities, which can be indicated by multiple bits. For example, the scheduled PUSCH has multiple priorities, such as high, higher, low, and lowest, which can be indicated by two bits in the priority indicator.

[0252] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the priority of the specified PUSCH in the embodiments of the present disclosure.

[0253] Step 92, in response to the priority corresponding to the specified PUSCH being the specified priority, determining a plurality of LBT detection positions corresponding to the specified PUSCH.

[0254] It should be noted that in the present disclosure, step 91 can be performed first, and then step 92 can be performed, or step 92 can be performed first, and then step 91 can be performed, or step 91 and step 92 can be performed in parallel, etc. The present disclosure does not limit this.

[0255] Step 93, receiving each repetition of the specified PUSCH at the plurality of LBT detection positions.

[0256] It should be noted that the specific content and implementation of step 92 and step 93 can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0257] It can be understood that when the priority corresponding to the specified PUSCH is not the specified priority, the network device can receive each repetition of the specified PUSCH from the LBT detection position according to the related art.

[0258] Or, when the scheduled PUSCH on the unlicensed spectrum is a non-specified PUSCH, the network device can receive each repetition of the specified PUSCH from the LBT detection position according to the related art.

[0259] In the embodiments of the present disclosure, the network device can send second indication information to the terminal device, wherein the second indication information is used to indicate the priority of the specified PUSCH to the terminal device, when the priority corresponding to the specified PUSCH is the specified priority, the multiple LBT detection positions corresponding to the specified PUSCH can be determined, and then each repetition of the specified PUSCH can be received at the multiple LBT detection positions. In this way, by receiving each repetition of the specified PUSCH at multiple possible LBT detection positions, the probability of channel occupation is increased, and the delay of service transmission is reduced.
