[0041] To facilitate understanding of the present disclosure, some concepts involved in the embodiments of the present disclosure are briefly introduced here.

[0042] 1. Transmission occasion (TO)

[0043] A transmission opportunity includes the time domain resources for transmitting data once. A transmission opportunity includes one or more symbols. When multiple transmission opportunities are available, and multiple transmission opportunities are used for repeated transmission, multiple copies of the same data are sent repeatedly over the multiple transmission opportunities. In this case, a single data transmission over a single transmission opportunity is referred to as a repeated transmission. These multiple copies of the same data refer to multiple, identical or different, RVs (redundancy versions) obtained from the same information bits after channel coding.

[0044] In order to better understand the method and apparatus for determining a time domain resource transmission position disclosed in an embodiment of the present disclosure, the communication system to which the embodiment of the present disclosure is applicable is first described below.

[0045] See Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure.

[0049] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0050] The following describes in detail a method and apparatus for determining a time domain resource transmission position provided by the present disclosure with reference to the accompanying drawings.

[0051] See Figure 2 , Figure 2 This is a flowchart of a method for determining a time domain resource transmission position provided by an embodiment of the present disclosure.

[0052] like Figure 2 As shown, the method is applied to a terminal device, and the method may include but is not limited to the following steps:

[0053] S21: Perform synchronization signal block SSB measurement to determine the target SSB index, where the target SSB index corresponds to the target beam direction.

[0054] In an embodiment of the present disclosure, the terminal device determines the target SSB index through SSB (Synchronization signal and PBCH block) measurement, wherein the target SSB index corresponds to the target beam direction, the target beam may be the optimal beam, and the target SSB index corresponds to the optimal beam direction.

[0055] It should be noted that, in the embodiment of the present disclosure, the target SSB index corresponds to the target beam direction, and the target beam can also be a beam other than the optimal beam. The embodiment of the present disclosure does not impose any specific restrictions on this.

[0056] In some embodiments, signal quality measurements are performed on a plurality of SSBs to determine a target SSB, and a target SSB index of the target SSB is determined.

[0057] Exemplarily, in an embodiment of the present disclosure, the terminal device determines the target SSB by measuring SS-RSRP (synchronization signal reference signal received power, or synchronization signal based reference signal received power). The target SSB may be the best SSB, and the best SSB has the best measured signal quality. The target SSB index of the target SSB is then determined.

[0058] S22: Determine the target retransmission timing TO according to the target SSB index; and perform small data packet transmission SDT according to the target repetition TO, wherein the target repetition TO is the TO corresponding to the Nth repetition transmission in the SDT, and N is a positive integer.

[0059] It should be noted that in the embodiment of the present disclosure, each SSB in the multiple SSBs of the SSB burst corresponds to the TO corresponding to the Nth repeated transmission in the SDT. By measuring the multiple SSBs in the SSB burst, an SSB with stronger channel quality is selected as the target SSB, and the TO corresponding to the Nth repeated transmission in the corresponding SDT is determined according to the target SSB, and the TO corresponding to the Nth repeated transmission in the SDT is determined as the target repeated TO.

[0060] In the embodiment of the present disclosure, after determining the target repetition TO, the terminal device can perform SDT according to the target repetition TO.

[0061] It can be understood that in the embodiment of the present disclosure, the TO corresponding to the repeated transmissions other than the Nth repeated transmission in the SDT can be associated with the target SSB of the target SSB index, so that when the target SSB index is determined, all repeated transmissions in the SDT can be determined.

[0062] In some embodiments, a synchronization signal block SSB measurement is performed to determine a target SSB index, wherein the target SSB index corresponds to a target beam direction, and a target repetition transmission timing TO is determined based on the target SSB index; and based on the target repetition TO, a small data packet transmission SDT is performed, wherein the target repetition TO is the TO corresponding to the Nth repetition transmission in the SDT, and N is a positive integer; according to the protocol provisions, the target repetition TO is determined to be the N in the TO corresponding to the Nth repetition transmission in the SDT, or, according to the base station configuration or instruction, the target repetition TO is determined to be the N in the TO corresponding to the Nth repetition transmission in the SDT.

[0063] Exemplarily, according to the protocol provisions, when N in the TO corresponding to the Nth repeated transmission in the SDT is 1, according to the protocol provisions, the target repeated TO is determined to be the TO corresponding to the 1st repeated transmission in the SDT, and the target repeated TO is selected for the 1st repeated transmission of the SDT.

[0064] Exemplarily, when N in the TO corresponding to the Nth repeated transmission in the SDT is determined according to the base station configuration or indication, the target repeated TO is determined according to the base station configuration or indication to be the TO corresponding to the 1st repeated transmission in the SDT, and the target repeated TO is selected for the 1st repeated transmission of the SDT.

[0065] It should be noted that the above examples are for illustration only and are not intended to be specific limitations on the embodiments of the present disclosure. According to the protocol provisions, or according to the base station configuration or instructions, the target repetition TO is determined to be the Nth repeated transmission in the SDT, and the N in the TO corresponding to the Nth repeated transmission can be other parameters other than 1.

[0066] In some embodiments, the number of repeated transmissions is M times, where N is less than or equal to M, M is a positive integer, and the number of TOs is the number of SSBs plus the number of repeated transmissions M minus 1.

[0067] In an exemplary embodiment, Figure 3 As shown, there are 4 SSBs in the SSBset (synchronization signal block set) configured by a CG (configured grant), and the number of repeated transmissions M is 4 times, so the number of TOs can be determined as the number of SSBs 4 plus the number of repeated transmissions 4 minus 1, and the number of TOs is 7.

[0068] Assuming that N is 1, the first four TOs are used to transmit the first repeated transmission in the SDT, and the last three TOs are used to transmit the remaining three repeated transmissions in the SDT.

[0069] certainly, Figure 3 The example shown is for illustration only. In the embodiment of the present disclosure, N can also be 3, or the third repeated transmission in the SDT can be associated with the target SSB index. Then the first TO is used to transmit the first repeated transmission in the SDT, the second TO is used to transmit the second repeated transmission in the SDT, the third, fourth, fifth, and sixth TOs are used to transmit the third repeated transmission in the SDT, and the seventh TO is used to transmit the fourth repeated transmission in the SDT.

[0070] In the embodiment of the present disclosure, N may be configured or indicated by the base station, may be specified by the protocol, or may be indicated by other implicit means, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0071] In some embodiments, the SSB indexes associated with the TO corresponding to the M repeated transmissions are all target SSB indexes.

[0072] In the embodiment of the present disclosure, on the basis of associating the target repetition TO with the target SSB index, in addition to the target repetition TO of the Nth repetition transmission being associated with the target SSB index in the M repetition transmissions, other times of repetition transmissions can also be associated with the target SSB index.

[0073] In some embodiments, TO corresponding to M repeated transmissions constitute a target physical uplink shared channel opportunity PO.

[0074] In the exemplary embodiment, please continue to see Figure 3There are 4 SSBs in the SSB set (synchronization signal block set) configured by a CG (configured grant), and the number of repeated transmissions M is 4 times. Therefore, the number of TOs can be determined as the number of SSBs 4 plus the number of repeated transmissions 4 minus 1, and the number of TOs is 7.

[0075] In one example, assuming N is 1, the first four TOs are used to transmit the first repetition of the SDT, and the last three are used to transmit the remaining three repetitions of the SDT. The terminal device determines through SSB measurement that the signal quality of SSB#2 corresponding to TO#2 is the best. The terminal device will select TO#2 for the first repetition of the SDT, and then use TO#4, TO#5, and TO#6 to complete the remaining three repetitions.

[0076] Among them, TO#2, TO#4, TO#5 and TO#6 can form a target PO.

[0077] It should be noted that TO#4, TO#5 and TO#6 occupied by the other three repeated transmissions can also be associated with SSB#1.

[0078] It should also be noted that, in the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute a target PO.

[0079] In another example, assuming N is 1, the first four TOs are used to transmit the first repetition of the SDT, and the last three are used to transmit the remaining three repetitions of the SDT. The terminal device determines through SSB measurement that SSB#1 corresponding to TO#1 has the best signal quality. The terminal device will select TO#1 for the first repetition of the SDT, and then use TO#4, TO#5, and TO#6 to complete the remaining three repetitions.

[0080] Among them, TO#1, TO#4, TO#5 and TO#6 can form a target PO.

[0081] It should be noted that TO#4, TO#5 and TO#6 occupied by the other three repeated transmissions can also be associated with SSB#1.

[0082] It should also be noted that, in the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute a target PO.

[0083] In the above exemplary embodiment of the present disclosure, the number of TOs is the number of SSBs (4) plus the number of repeated transmissions (4) minus 1, and the number of TOs is determined to be 7.

[0084] It should be noted that for M repeated transmissions of SDT, each SSB can correspond to M TOs, and M TOs are used for M repeated transmissions of SDT. In this case, if the SSB burst has K SSBs, the number of TOs needs to be configured as K*M, where K and M are both positive integers.

[0085] However, in the embodiment of the present disclosure, it is only necessary to configure the number of TOs to be the number of SSBs K plus the number of repeated transmissions M minus 1, so as to achieve M repeated transmissions of SDT, which greatly saves time and frequency resources and improves spectrum efficiency.

[0086] In some embodiments, a configuration authorization cycle of SDT includes multiple POs, and the redundant version RV sequence corresponding to TO in the target PO is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}; the RV corresponding to TO in other POs among the multiple POs except the target PO is RV0.

[0087] By implementing the embodiments of the present disclosure, a terminal device performs synchronization signal block (SSB) measurement to determine a target SSB index, where the target SSB index corresponds to a target beam direction, and determines a repeat transmission timing (TO) based on the target SSB index. Furthermore, a small data packet transmission (SDT) is performed based on the target repeat TO, where the target repeat TO is the TO corresponding to the Nth repeat transmission in the SDT, where N is a positive integer. This allows for the configuration of repeated transmissions of the authorized CG-SDT, significantly saving time-frequency resources and improving spectrum efficiency.

[0088] See Figure 4 , Figure 4 This is a flowchart of another method for determining the time domain resource transmission position provided by an embodiment of the present disclosure.

[0089] like Figure 4 As shown, the method is applied to a terminal device, and the method may include but is not limited to the following steps:

[0090] S41: Perform synchronization signal block SSB measurement to determine the target SSB index, where the target SSB index corresponds to the target beam direction.

[0091] For the relevant description of S41 in the embodiment of the present disclosure, reference can be made to the relevant description of S21 in the above example, which will not be repeated here.

[0092] S42: Determine the target repeated transmission timing TO according to the target SSB index; and perform small data packet transmission SDT according to the target repeated TO, wherein the target repeated TO is the TO corresponding to the Nth repeated transmission in the SDT, and N is a positive integer; the SDT includes multiple configuration authorization cycles, and one configuration authorization cycle includes one PO, one configuration authorization cycle among the multiple configuration authorization cycles has multiple TOs for repeated transmission, and other configuration authorization cycles among the multiple configuration authorization cycles have one TO for repeated transmission.

[0093] In some embodiments, the TO for repeated transmission in other configuration authorization periods corresponds to the Lth repeated transmission, where L is agreed upon by the protocol, or configured or indicated by the base station, and L is a positive integer.

[0094] It can be understood that one configuration authorization period among other configuration authorization periods has a TO for repeated transmission, and the unique TO can be any repeated transmission. In the embodiment of the present disclosure, according to the protocol agreement, or the base station configuration or instruction, one configuration authorization period among other configuration authorization periods has a TO for repeated transmission corresponding to the Lth repeated transmission.

[0095] In an embodiment of the present disclosure, different SSBs are associated with different configuration authorization periods, and one configuration authorization period among multiple configuration authorization periods has multiple TOs for repeated transmission. The configuration authorization period having multiple TOs for repeated transmission is the nth configuration authorization period among the multiple configuration authorization periods, which can be determined according to the base station configuration or indication.

[0096] In some embodiments, multiple configuration grant periods use the same hybrid automatic repeat request (HARQ) process number (HPN).

[0097] In an exemplary embodiment, the terminal device determines a target SSB index by performing SSB measurement, where the target SSB index corresponds to a target beam direction, where the signal quality of the target beam is the best, such as Figure 5 As shown, SDT includes 4 CG cycles (configuration authorization cycles), one CG cycle includes one PO, CG cycle #4 among the 4 CG cycles has 4 TOs for repeated transmission, and CG cycle #1, CG cycle #2 and CG cycle #3 among the 4 CG cycles have one TO for repeated transmission.

[0098] In one example, the terminal device determines that the best beam corresponds to 1 of CG cycle #2 by performing SSB measurement. stThe first repetition transmission is performed on the repetition resource, and the remaining repetition transmissions are performed on the resource configured with non-first repetition. For example, when the number of repetitions is 4, at 2 of CG cycle #4 nd repetition resource to transmit the second repetition, in CG cycle #4 3 rd repetition resource to perform the third repetition transmission, in CG cycle #4 th repetition resources to perform the fourth repetition transmission.

[0099] It should be noted that the configuration authorization period for different repeated transmission times may be determined according to the base station configuration. The base station may configure the configuration authorization period for different repeated transmission times through a bitmap or code point.

[0100] In some embodiments, the redundant version RV sequence corresponding to a configuration authorization period having multiple TOs for repeated transmission among multiple configuration authorization periods is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}; the RV corresponding to multiple configuration authorization periods having one TO for repeated transmission among multiple configuration authorization periods is RV0.

[0101] It should be noted that, in the embodiment of the present disclosure, the above-mentioned S41 and S42 can be implemented separately, or can be implemented together with any other embodiment of the present disclosure. For example, they can be implemented together with S21 and S22 in the present disclosure. The embodiment of the present disclosure does not impose any specific restrictions on this.

[0102] See Figure 6 , Figure 6 This is a flowchart of another method for determining the time domain resource transmission position provided by an embodiment of the present disclosure.

[0103] like Figure 6 As shown, the method is applied to a base station, and the method may include but is not limited to the following steps:

[0104] S61: Receive the SDT of the terminal device and determine the target repetition TO, where the target repetition TO is the TO corresponding to the Nth repetition transmission in the SDT, and N is a positive integer.

[0105] In an embodiment of the present disclosure, the terminal device determines the target SSB index through SSB (Synchronization signal and PBCH block) measurement, wherein the target SSB index corresponds to the target beam direction, the target beam can be the optimal beam, and the target SSB index corresponds to the optimal beam direction. Based on this, the SDT is sent in the determined optimal beam, so that the base station receives the SDT of the terminal device and can determine the target repetition TO, wherein the target repetition TO is the TO corresponding to the Nth repeated transmission in the SDT, and N is a positive integer.

[0106] It should be noted that, in the embodiment of the present disclosure, the target SSB index corresponds to the target beam direction, and the target beam can also be a beam other than the optimal beam. The embodiment of the present disclosure does not impose any specific restrictions on this.

[0107] S62: Determine the target SSB index according to the target repetition TO, where the target SSB index corresponds to the target beam direction.

[0108] In some embodiments, the base station configures or indicates that the target repetition TO is N in the TO corresponding to the Nth repetition transmission in the SDT.

[0109] It should be noted that in the embodiment of the present disclosure, each SSB in the multiple SSBs of the SSB burst corresponds to the TO corresponding to the Nth repeated transmission in the SDT. By measuring the multiple SSBs in the SSB burst, an SSB with stronger channel quality is selected as the target SSB, and the TO corresponding to the Nth repeated transmission in the corresponding SDT is determined according to the target SSB, and the TO corresponding to the Nth repeated transmission in the SDT is determined as the target repeated TO.

[0110] In the embodiment of the present disclosure, after determining the target repetition TO, the terminal device can perform SDT according to the target repetition TO.

[0111] It can be understood that in the embodiment of the present disclosure, repeated transmissions other than the Nth repeated transmission in the SDT can be associated with the target SSB of the target SSB index, so that all repeated transmissions in the SDT can be determined when the target SSB index is determined.

[0112] In some embodiments, the number of repeated transmissions is M times, where N is less than or equal to M, M is a positive integer, and the number of TOs is the number of SSBs plus the number of repeated transmissions M minus 1.

[0113] In an exemplary embodiment, Figure 3As shown, there are 4 SSBs in the SSBset (synchronization signal block set) configured by a CG (configured grant), and the number of repeated transmissions M is 4 times, so the number of TOs can be determined as the number of SSBs 4 plus the number of repeated transmissions 4 minus 1, and the number of TOs is 7.

[0114] Assuming that N is 1, the first four TOs are used to transmit the first repeated transmission in the SDT, and the last three TOs are used to transmit the remaining three repeated transmissions in the SDT.

[0115] certainly, Figure 3 The example shown is for illustration only. In the embodiment of the present disclosure, N can also be 3, or the third repeated transmission in the SDT can be associated with the target SSB index. Then the first TO is used to transmit the first repeated transmission in the SDT, the second TO is used to transmit the second repeated transmission in the SDT, the third, fourth, fifth, and sixth TOs are used to transmit the third repeated transmission in the SDT, and the seventh TO is used to transmit the fourth repeated transmission in the SDT.

[0116] In some embodiments, the SSB indexes associated with the TO corresponding to the M repeated transmissions are all target SSB indexes.

[0117] In the embodiment of the present disclosure, on the basis of associating the target repetition TO with the target SSB index, in addition to the target repetition TO of the Nth repetition transmission being associated with the target SSB index in the M repetition transmissions, other times of repetition transmissions can also be associated with the target SSB index.

[0118] In some embodiments, TO corresponding to M repeated transmissions constitute a target physical uplink shared channel opportunity PO.

[0119] In the exemplary embodiment, please continue to see Figure 3 There are 4 SSBs in the SSB set (synchronization signal block set) configured by a CG (configured grant), and the number of repeated transmissions M is 4 times. Therefore, the number of TOs can be determined as the number of SSBs 4 plus the number of repeated transmissions 4 minus 1, and the number of TOs is 7.

[0120] In one example, assuming N is 1, the first four TOs are used to transmit the first repetition of the SDT, and the last three are used to transmit the remaining three repetitions of the SDT. The terminal device determines through SSB measurement that the signal quality of SSB#2 corresponding to TO#2 is the best. The terminal device will select TO#2 for the first repetition of the SDT, and then use TO#4, TO#5, and TO#6 to complete the remaining three repetitions.

[0121] Among them, TO#2, TO#4, TO#5 and TO#6 can form a target PO.

[0122] It should be noted that TO#4, TO#5 and TO#6 occupied by the other three repeated transmissions can also be associated with SSB#1.

[0123] It should also be noted that, in the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute a target PO.

[0124] In another example, assuming N is 1, the first four TOs are used to transmit the first repetition of the SDT, and the last three are used to transmit the remaining three repetitions of the SDT. The terminal device determines through SSB measurement that SSB#1 corresponding to TO#1 has the best signal quality. The terminal device will select TO#1 for the first repetition of the SDT, and then use TO#4, TO#5, and TO#6 to complete the remaining three repetitions.

[0125] Among them, TO#1, TO#4, TO#5 and TO#6 can form a target PO.

[0126] It should be noted that TO#4, TO#5 and TO#6 occupied by the other three repeated transmissions can also be associated with SSB#1.

[0127] It should also be noted that, in the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute a target PO.

[0128] In the above exemplary embodiment of the present disclosure, the number of TOs is the number of SSBs (4) plus the number of repeated transmissions (4) minus 1, and the number of TOs is determined to be 7.

[0129] It should be noted that for M repeated transmissions of SDT, each SSB can correspond to M TOs, and M TOs are used for M repeated transmissions of SDT. In this case, if the SSB burst has K SSBs, the number of TOs needs to be configured as K*M, where K and M are both positive integers.

[0130] However, in the embodiment of the present disclosure, it is only necessary to configure the number of TOs to be the number of SSBs K plus the number of repeated transmissions M minus 1, so as to achieve M repeated transmissions of SDT, which greatly saves time and frequency resources and improves spectrum efficiency.

[0131] In some embodiments, a configuration authorization cycle of SDT includes multiple POs, and the redundant version RV sequence corresponding to TO in the target PO is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}; the RV corresponding to TO in other POs among the multiple POs except the target PO is RV0.

[0132] By implementing the disclosed embodiments, a base station receives the SDT of a terminal device and determines a target repetition TO, where the target repetition TO is the TO corresponding to the Nth repetition transmission in the SDT, where N is a positive integer. A target SSB index is determined based on the target repetition TO, where the target SSB index corresponds to the target beam direction. This allows for the configuration of repeated transmissions of the authorized CG-SDT, significantly saving time-frequency resources and improving spectrum efficiency.

[0133] The detailed description of embodiments S61 and S62 of the present disclosure can be found in the relevant description of the above embodiments of the present disclosure, and will not be repeated here.

[0134] By implementing the embodiments of the present disclosure, repeated transmission of the configuration authorization CG-SDT can be achieved.

[0135] See Figure 7 , Figure 7 This is a flowchart of another method for determining the time domain resource transmission position provided by an embodiment of the present disclosure.

[0136] like Figure 7 As shown, the method is applied to a base station, and the method may include but is not limited to the following steps:

[0137] S71: Receive the SDT of the terminal device and determine the target repetition TO, wherein the target repetition TO is the TO corresponding to the Nth repeated transmission in the SDT, and N is a positive integer; the SDT includes multiple configuration authorization cycles, and one configuration authorization cycle includes one PO, one configuration authorization cycle among the multiple configuration authorization cycles has multiple TOs for repeated transmission, and other configuration authorization cycles among the multiple configuration authorization cycles have one TO for repeated transmission.

[0138] S72: Determine the target SSB index according to the target repetition TO, where the target SSB index corresponds to the target beam direction.

[0139] In some embodiments, the base station configures or instructs other configurations of L for the Lth repeated transmission corresponding to TO for repeated transmission in the authorization period, where L is a positive integer.

[0140] In some embodiments, multiple configuration grant periods use the same HARQ process number HPN.

[0141] In some embodiments, the redundant version RV sequence corresponding to a configuration authorization period having multiple TOs for repeated transmission among multiple configuration authorization periods is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}; the RV corresponding to multiple configuration authorization periods having one TO for repeated transmission among multiple configuration authorization periods is RV0.

[0142] For detailed descriptions of embodiments S71 and S72 of the present disclosure, please refer to the relevant descriptions of the above embodiments of the present disclosure, which will not be repeated here.

[0143] It should be noted that, in the embodiment of the present disclosure, the above-mentioned S71 and S72 can be implemented separately, or can be implemented together with any other embodiment of the present disclosure. For example, they can be implemented together with S61 and S62 in the present disclosure. The embodiment of the present disclosure does not impose any specific restrictions on this.

[0144] See Figure 8 , Figure 8 This is a flowchart of another method for determining the time domain resource transmission position provided by an embodiment of the present disclosure.

[0145] like Figure 8 As shown, the method is applied to a base station, and the method may include but is not limited to the following steps:

[0146] S81: Receive the SDT of the terminal device and determine the target repetition TO, wherein the target repetition TO is the TO corresponding to the Nth repeated transmission in the SDT, and N is a positive integer; determining the target repetition TO includes: performing energy detection on multiple TOs during the Nth repeated transmission; and determining the target repetition TO during the Nth repeated transmission based on the energy detection results of the multiple TOs.

[0147] S82: Determine the target SSB index according to the target repetition TO, where the target SSB index corresponds to the target beam direction.

[0148] In an embodiment of the present disclosure, the base station receives the SDT of the terminal device. When the SDT is repeated for the Nth time, the base station performs energy detection on multiple TOs. For example, RSRP measurement is performed on the DMRS. The highest signal quality is obtained by measurement. The base station can then determine on which TO the Nth repeated transmission is sent, thereby being able to obtain relevant information about the SSB index. Thereafter, when the terminal device subsequently repeats the SDT, it can be received in the target beam direction corresponding to the same SSB index.

[0149] In some embodiments, the base station indicates to the terminal device the time interval gap between TOs repeatedly transmitted by multiple users.

[0150] In the disclosed embodiment, the base station indicates to the terminal device the time interval gap between repeated TO transmissions of multiple users, so that the terminal device can repeat two adjacent SDTs within the indicated time interval gap. Thus, the base station can measure the energy of multiple TOs during the previous SDT in the time interval gap, determine which TO the previous SDT retransmission was sent on, and thus obtain relevant information about the SSB index. Subsequently, when the terminal device subsequently repeats the SDT, it uses the target beam direction corresponding to the same SSB index for reception, thereby effectively saving time domain resources.

[0151] It should be noted that, in the embodiment of the present disclosure, the above-mentioned S81 and S82 can be implemented separately, or can be implemented together with any other embodiment of the present disclosure. For example, they can be implemented together with S61 and S62 and / or S71 and S72 in the present disclosure.
