Detailed ways

For ease of understanding, terminology involved in the present disclosure is first introduced.

1. Listen before talk (LBT)

LBT is a channel access mechanism. Usually, the availability of channels 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 must be monitored first, and the clear channel assessment (CCA) must be performed. Data transmission is performed when the channel is idle.

2. Physical uplink shared channel (PUSCH)

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

3. Repetition type

When the repetition type of PUSCH is A, the specific transmission start position can be jointly indicated by indicating the continuous transmission symbol L and the start symbol position S. In PUSCH repetitiontypeA, each repetition is located in adjacent time slots, and the symbols occupy the same position in each time slot.

When the repetition type of PUSCH is B, it is a back-to-back repeated transmission, that is, the two PUSCHs are adjacent in the time domain, so that each repetition can be transmitted as soon as possible to reduce the delay. the goal of. In order to better understand the method for transmitting uplink data disclosed in the embodiments of the present disclosure, the following first describes a communication system to which the embodiments of the present disclosure are applicable.

It can be understood that the communication system described in the embodiments of the present disclosure is for the purpose of illustrating the technical solutions of the embodiments of the present disclosure more clearly, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. With the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

The method and device for transmitting uplink data provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 2, which is a schematic flowchart of a method for transmitting uplink data provided by an embodiment of the present disclosure, where the method is configured to be executed by a terminal device. As shown in Figure 2, the method may include but is not limited to the following steps:

Step 21: Determine the designated physical uplink shared channel PUSCH scheduled on the unlicensed spectrum, and the corresponding multiple listen-before-talk LBT detection positions.

Generally, when a terminal device performs service transmission on an unlicensed spectrum, it needs to perform LBT detection first, and when the LBT is successful, it can start to occupy the unlicensed spectrum for uplink transmission. If the LBT is unsuccessful, the terminal equipment cannot occupy the unlicensed spectrum for uplink transmission.

It can be understood that, when the terminal device monitors the interference on the unlicensed spectrum, such as noise, signal-to-noise ratio, etc., which is lower than the threshold value, it can be considered that the LBT is successful.

The threshold value may be a value agreed upon in the protocol, or may be a value configured by the network device for the terminal device, etc., which is not limited in the present disclosure.

In the present disclosure, when the unlicensed spectrum is used for service transmission, multiple LBT detection positions are set for the designated PUSCH, and monitoring is performed at each LBT detection position, so as to increase the probability of occupying the channel, thereby reducing the delay of service transmission as much as possible. .

Optionally, when at least two repetitions in the multiple repetitions corresponding to any PUSCH are connected end to end in the time domain, the terminal device at the starting position of the previous repetition among the at least two repetitions, When the monitoring is successful, the unlicensed spectrum can be occupied, and the at least two repetitions are continuously sent. Therefore, in the present disclosure, multiple LBTs may be set for the PUSCH corresponding to at least two repetitions that are connected end to end in the time domain, thereby increasing the probability that the PUSCH occupies a channel.

Optionally, when the repetition type (repetition type) of any PUSCH is B, it can be determined that any PUSCH is a designated PUSCH.

It can be understood that the two repetitions before and after the PUSCH repetition type B are connected in the time domain, so the PUSCH with repetition type B is determined as the specified PUSCH, which can be transmitted in units of smaller time resources. The probability of occupying the channel of the PUSCH is increased, thereby increasing the probability of its successful transmission, thereby achieving the purpose of reducing the delay.

Optionally, when the repetition type of any PUSCH is A, and the end position of the previous repetition in the two adjacent repetitions of any PUSCH is the start position of the next repetition, determine any PUSCH as the designated one. PUSCH.

It can be understood that when the PUSCH is repetition typeA, if the length of the consecutive symbol corresponding to one of its repetitions is 14, the repetition is adjacent to the next adjacent repetition in the time domain, so the PUSCH is determined as the specified repetition. The PUSCH can increase the probability of the PUSCH occupying the channel, thereby increasing the probability of its successful transmission and achieving the purpose of reducing the delay.

Optionally, after determining multiple LBT detection locations corresponding to the designated PUSCH scheduled on the unlicensed spectrum, the terminal device may perform LBT monitoring at each LBT detection location. If the LBT fails, the communication transmission cannot be performed, and the LBT detection can be continued at other LBT detection positions, thereby increasing the probability of channel occupation, thereby reducing the delay of service transmission, improving the utilization rate of uplink resources, and further improving the system. performance.

It can be understood that, when the terminal device transmits the PUSCH repetition on the unlicensed spectrum, there may be various situations whether the transmission of the PUSCH repetition ends.

For example, on the unlicensed spectrum, when the terminal device transmits the PUSCH repetition, the channel occupancy time (channel occupy time, COT) cannot be exceeded. If the COT is exceeded, the transmission of the PUSCH repetition needs to be terminated. Alternatively, the protocol stipulates that when invalid symbols are encountered, the PUSCH repetition cannot be sent on these invalid symbols. Therefore, after the LBT is successful, the terminal device may not be able to completely transmit all the PUSCH repetitions after the LBT detection position.

It can be understood that when the PUSCH scheduled on the unlicensed spectrum is an unspecified PUSCH, the unlicensed spectrum can be monitored only before the start of the first PUSCH repetition according to the related art. If LBT fails, multiple repetitions included in the PUSCH cannot be transmitted.

In this embodiment of the present disclosure, the terminal device may first determine multiple LBT detection locations corresponding to the designated PUSCH scheduled on the unlicensed spectrum, and then may perform LBT monitoring at the multiple LBT detection locations. 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.

Please refer to FIG. 3 , which is a schematic flowchart of a method for transmitting uplink data provided by an embodiment of the present disclosure, where the method is configured to be executed by a terminal device. As shown in Figure 3, the method may include but is not limited to the following steps:

Step 31: Determine the starting position of each repetition of the designated PUSCH scheduled on the unlicensed spectrum as an LBT detection position.

Optionally, in response to the repetition type of any PUSCH repetition type being B, determine that any PUSCH is the specified PUSCH; or, in response to the repetition type of any PUSCH being A, and two adjacent repetitions of any PUSCH The end position of the previous repetition is the start position of the next repetition, and any PUSCH is determined to be the designated PUSCH.

It should be noted that, for the specific content and implementation manner of the designated PUSCH, reference may be made to the descriptions of other embodiments of the present disclosure, which will not be repeated here.

For example, when the specified PUSCH is a PUSCH whose repetition type is 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 the LBT detection position, so as to determine There are a total of 4 LBT detection positions.

It should be noted that the above examples are only examples, and cannot be used as limitations on the number of repetitions of the PUSCH repetition, the LBT detection position, etc. in the embodiments of the present disclosure

Step 32, monitor the unlicensed spectrum at each LBT detection location.

It can be understood that after the terminal device determines multiple LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum, LBT monitoring can be performed at each LBT detection position, thereby increasing the probability of channel occupation and reducing The delay of service transmission.

Step 33, in response to the successful LBT at any LBT detection position, occupy the unlicensed spectrum to transmit each repetition of the designated PUSCH after any LBT detection position.

For example, there are a total of 4 LBT detection positions determined by the terminal device, 0, 1, 2, and 3, which are located at the respective time domain starting positions of PUSCH repetition 0, PUSCH repetition 1, PUSCH repetition 2, and PUSCH repetition 3. .

Therefore, the terminal device can first monitor the unlicensed spectrum at the LBT detection position 0, and if the LBT fails, it can monitor the unlicensed spectrum at the LBT detection position 1 again. If the terminal device succeeds in LBT at LBT detection position 1, then the terminal device can occupy the unlicensed spectrum to transmit the specified PUSCH repetition after the LBT detection position 1, that is, transmit PUSCH repetition 1, PUSCH repetition 2 and PUSCH repetition 3.

If the LBT fails at the LBT detection position 1, the unlicensed spectrum may be monitored again at the LBT detection position 2. If the terminal device succeeds in LBT at LBT detection position 2, then the terminal device can occupy the unlicensed spectrum to transmit PUSCH repetition 2 and PUSCH repetition 3 after the LBT detection position 2.

It should be noted that the above examples are only examples, and cannot be used as limitations on the manner of occupying unlicensed spectrum to transmit repetition in the embodiments of the present disclosure.

It should be noted that, after the LBT is successful, when the terminal equipment performs the transmission of each repetition of the designated PUSCH after the LBT detection position on the unlicensed spectrum, whether the transmission of the PUSCH repetition is completed can be referred to the descriptions of other embodiments of the present disclosure, It will not be repeated here.

In this embodiment of the present disclosure, the terminal device may first determine the starting position of each repetition of the designated PUSCH scheduled on the unlicensed spectrum as the LBT detection position, and then monitor the unlicensed spectrum at each LBT detection position. When the LBT at any LBT detection position is successful, the unlicensed spectrum is occupied to transmit each repetition of the designated PUSCH after any 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.

Please refer to FIG. 4 , which is a schematic flowchart of a method for transmitting uplink data provided by an embodiment of the present disclosure, where the method is configured to be executed by a terminal device. As shown in Figure 4, the method may include but is not limited to the following steps:

Step 41: Determine the start position of the specified repetition of the specified PUSCH scheduled on the unlicensed spectrum as an LBT detection position.

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

For example, when the specified PUSCH is a PUSCH whose repetition type is B, the number of repetitions of the PUSCH repetition is 4, which are 0, 1, 2, and 3, respectively. The RVs of the four repetitions are 0, 2, 3, and 1, respectively. The RVs that the terminal device can self-decode are RV0 and RV3, respectively, and RV0 and RV3 are designated RVs. Therefore, the terminal device can determine the respective repetitions of RV0 and RV3, that is, the respective time domain starting positions of PUSCH repetition 0 and PUSCH repetition 2, as the LBT detection position.

It should be noted that, the above examples are merely illustrative, and cannot be used as limitations on determining the LBT detection position and the like in the embodiments of the present disclosure.

Optionally, the terminal device may also determine the specified repetition from multiple repetitions according to the instruction of the network device. This disclosure does not limit this.

Step 42, monitor the unlicensed spectrum at each LBT detection location.

Step 43 , in response to the successful LBT at any LBT detection position, occupy the unlicensed spectrum to transmit each repetition of the designated PUSCH after any LBT detection position.

For example, the specified number of repetitions of the PUSCH repetition is 4, which are 0, 1, 2, and 3, respectively, and the RVs of the 4 repetitions are 0, 2, 3, and 1, respectively. The RVs that the terminal device can self-decode are RV0 and RV3, respectively, and RV0 and RV3 are designated RVs. Therefore, the terminal device can determine the respective repetitions of RV0 and RV3, that is, the respective time domain starting positions of repetition 0 and repetition 2, as the LBT detection positions: LBT detection position 0 and LBT detection position 1.

Therefore, the terminal device can first monitor the unlicensed spectrum at the LBT detection position 0, and if the LBT fails, it can monitor the unlicensed spectrum again at the LBT detection position 1. If the LBT is successful at LBT detection position 1, then the terminal device can occupy the unlicensed spectrum to transmit each repetition of the PUSCH specified after the LBT detection position 1, that is, transmit PUSCH repetition 2 and PUSCH repetition 3.

In this embodiment of the present disclosure, the terminal device may 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 monitor the unlicensed spectrum at each LBT detection position. When the LBT at any LBT detection position is successful, the unlicensed spectrum is occupied to transmit each repetition of the designated PUSCH after any 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.

Please refer to FIG. 5, which is a schematic flowchart of a method for transmitting uplink data provided by an embodiment of the present disclosure, where the method is configured to be executed by a terminal device. As shown in Figure 5, the method may include but is not limited to the following steps:

Step 51: Determine, according to the first indication information, multiple LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum.

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

Therefore, the terminal device may first receive the first indication information, and then, according to the indication of the first indication information, may determine multiple LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum.

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 determining that the PUSCH whose repetition type is B is the designated PUSCH and that the number of repetitions of the PUSCH repetition is 4, the terminal device can determine, according to the first indication information, that the starting position of each repetition of the PUSCH is LBT detection. position, so it can be determined that there are 4 LBT detection positions.

It should be noted that the above examples are only examples, and cannot be used as limitations on the first indication information, the LBT detection position, etc. in the embodiments of the present disclosure

Optionally, the terminal device may further determine, according to the agreement, multiple LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum.

For example, the protocol stipulates that the starting position of each repetition of the specified PUSCH is the LBT detection position. Therefore, after the terminal device determines that the PUSCH whose repetition type is B is the specified PUSCH and that the number of repetitions of the PUSCH repetition is 4, according to the agreement, it can be determined: the start of each repetition of the PUSCH whose repetition type is B is B. The position is the LBT detection position, so it can be determined that there are 4 LBT detection positions.

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

Step 52, monitor the unlicensed spectrum at each LBT detection location.

Step 53, in response to the successful LBT at any LBT detection position, occupy the unlicensed spectrum to transmit each repetition of the designated PUSCH after any LBT detection position.

It should be noted that, for the specific content and specific implementation manner of step 52 and step 53, reference may be made to the descriptions of other embodiments of the present disclosure, and details are not repeated here.

In this embodiment of the present disclosure, the terminal device may determine, according to the first indication information, multiple LBT detection positions corresponding to the designated PUSCH scheduled on the unlicensed spectrum, and then monitor the unlicensed spectrum at each LBT detection position. When the LBT at an LBT detection position is successful, the unlicensed spectrum is occupied to transmit each repetition of the designated PUSCH after any 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.

Please refer to FIG. 6, which is a schematic flowchart of a method for transmitting uplink data provided by an embodiment of the present disclosure, where the method is configured to be executed by a terminal device. As shown in Figure 6, the method may include but is not limited to the following steps:

Step 61: Determine the priority of the designated PUSCH scheduled on the unlicensed spectrum according to the second indication information.

It can be understood that the second indication information may be indication information sent by the network device to the terminal device, where the second indication information may indicate the priority of the designated PUSCH scheduled on the unlicensed spectrum.

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

Optionally, the second indication information may be downlink control information (downlink control information, DCI), or may also be other information, etc., which is not limited in the present disclosure.

Optionally, the terminal device may 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.

For example, when the priority indicator has 1 bit to indicate the priority, it can indicate high and low priorities.

Alternatively, when the priority indicator has multiple bits, multiple priorities can be indicated. For example, when the priority indicator has 2 bits, it can indicate multiple priorities such as high, high, low, and low.

It should be noted that the above examples are only examples, and cannot be used as limitations on the priorities of the PUSCHs specified in the embodiments of the present disclosure.

Step 62, in response to the priority corresponding to the designated PUSCH being the designated priority, determine multiple LBT detection positions corresponding to the designated PUSCH.

Optionally, the specified priority may be agreed in a protocol or configured by a network device, which is not limited in the present disclosure.

For example, when the priority indicator has only 1 bit, it can indicate high and low priorities, and the specified priority is the high priority. Therefore, when the terminal device determines that the priority of the designated PUSCH is a high priority according to the instruction of the DCI, it can further determine multiple LBT detection positions corresponding to the designated PUSCH.

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 so on. Therefore, when the terminal device determines that the priority of the designated PUSCH is the designated priority according to the instruction of the DCI, it can further determine multiple LBT detection positions corresponding to the designated PUSCH.

It should be noted that the above examples are only examples, and cannot be used as limitations on the priorities and the like specified in the embodiments of the present disclosure.

It should be noted that, for the specific content and implementation manner of determining the multiple LBT detection positions corresponding to the specified PUSCH, reference may be made to the descriptions of other embodiments of the present disclosure, which will not be repeated here.

According to the related technology, only before the start of the first PUSCH repetition is authorized. monitor the spectrum. If LBT fails, multiple repetitions included in the PUSCH cannot be transmitted.

Alternatively, when the PUSCH scheduled on the unlicensed spectrum is an unspecified PUSCH, the unlicensed spectrum may be monitored only before the start of the first PUSCH repetition according to the related art. If LBT fails, multiple repetitions included in the PUSCH cannot be transmitted.

Step 63, monitor the unlicensed spectrum at each LBT detection location.

Step 64, in response to the successful LBT at any LBT detection position, occupy the unlicensed spectrum to transmit each repetition of the designated PUSCH after any LBT detection position.

When the LBT is successful at any LBT detection position, you can occupy the unlicensed spectrum to transmit the designated PUSCH after any LBT detection position. of each repetition. 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.

Correspondingly, the network device can receive the service data transmitted by the terminal device. .

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

The threshold value may be a value agreed upon in a protocol, or may also be a value configured by a network device, etc., which is not limited in the present disclosure.

Correspondingly, the network device can determine The plurality of LBTs detect positions so as to receive data transmitted by the terminal device.

Step 72: Receive each repetition of the specified PUSCH at multiple LBT detection positions.

Wherein, after determining multiple LBT detection positions corresponding to the specified PUSCH scheduled on the unlicensed spectrum, the network device may receive each repetition of the specified PUSCH at each LBT detection position.

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

It can be understood that when the PUSCH scheduled on the unlicensed spectrum is an unspecified PUSCH, the network device can receive each repetition of the specified PUSCH starting from the LBT detection position according to the related art.

The RVs of the four repetitions are 0, 2, 3, and 1, respectively. The RVs that the terminal device can self-decode are RV0 and RV3, respectively, and RV0 and RV3 are designated RVs. Therefore, the network device can determine the respective repetitions of RV0 and RV3, that is, the respective time domain starting positions of PUSCH repetition 0 and PUSCH repetition 2, as the LBT detection positions.

Optionally, the network device may also determine the start position of each repetition of the specified PUSCH as an LBT detection position.
