[0029] To facilitate understanding of the present disclosure, this section briefly introduces some concepts related to embodiments of the present disclosure.

[0030] 1. Transmission occasion (abbreviated as TO) A transmission occasion includes a time domain resource for transmitting data once. One transmission occasion includes one or more codes. When multiple transmission occasions exist and are used for repeated transmission, multiple identical data are repeatedly transmitted in the multiple transmission occasions. In this case, one data transmission in one transmission occasion can be called one repeated transmission. The multiple identical data refers to multiple identical or different RVs (redundancy versions) obtained after channel coding the same information bits.

[0031] To better understand the method and apparatus for determining time domain resource transmission positions disclosed in the embodiments of the present disclosure, the following first describes a communication system applied to the embodiments of the present disclosure.

[0032] Referring to FIG. 1, FIG. 1 is a schematic architecture diagram of a communication system provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, one base station and one terminal device.

[0033] The technical solutions of the embodiments of the present disclosure may be applied to various communication systems, such as a long term evolution (LTE) system, a fifth generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems.

[0036] It should be noted that the communication systems described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and are not intended to limit the technical solutions provided by the embodiments of the present disclosure. As those skilled in the art will appreciate, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure can also be applied to similar technical problems.

[0037] In the configuration authorization CG-SDT, the terminal device obtains the optimal downlink beam by measuring different SSBs, and then selects the associated physical uplink shared channel occasion (PO) to perform SDT. This method can implicitly report the optimal downlink beam to the base station.

[0038] The method and apparatus for determining time domain resource transmission positions provided by the present disclosure will be introduced in detail below in combination with the drawings.

[0039] Please refer to FIG. 2, which is a flowchart of a method for determining a time domain resource transmission position provided by an embodiment of the present disclosure.

[0040] As shown in FIG. 2, the method is applied to a terminal device, and may include the following steps 21 to 22.

[0041] S21, perform synchronization signal block (SSB) measurements to determine the target SSB index corresponding to the target beam direction.

[0042] In an embodiment of the present disclosure, a terminal device determines a target SSB index by measuring an SSB (Synchronization signal and PBCH block), where the target SSB index corresponds to a target beam direction, the target beam may be an optimal beam, and the target SSB index is the optimal beam direction.

[0043] In addition, in the embodiment of the present disclosure, the target SSB index corresponds to the target beam direction, and the target beam may be a beam other than the optimal beam, and is not limited to this in the embodiment of the present disclosure.

[0044] In some embodiments, a target SSB is determined by performing signal quality measurements on multiple SSBs and determining a target SSB index for the target SSB.

[0045] For example, in an embodiment of the present disclosure, the terminal device determines a 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 an optimal SSB, and the signal quality measured by the optimal SSB is the best, and then determines a target SSB index of the target SSB.

[0046] S22, determine a target repeat transmission occasion (TO) based on the target SSB index, and perform a small data transmission (SDT) based on the target repeat TO, where the target repeat TO is a TO corresponding to the Nth repeat transmission in the SDT, and N is a positive integer.

[0047] In an embodiment of the present disclosure, each of the multiple SSBs in an SSB burst corresponds to a TO corresponding to the Nth repeated transmission in the SDT, and by measuring the multiple SSBs in the SSB burst, one SSB with high channel quality is selected as the target SSB, and based on the target SSB, the TO corresponding to the Nth repeated transmission in the corresponding SDT is determined, and the TO corresponding to the Nth repeated transmission in the SDT is determined to be the target repeated TO.

[0048] In the embodiment of the present disclosure, after determining the target repetition TO, the terminal device can perform SDT based on the target repetition TO.

[0049] In addition, in an embodiment of the present disclosure, in the SDT, TOs corresponding to other repeated transmissions than the Nth repeated transmission may be associated with the target SSB of the target SSB index, thereby determining all repeated transmissions in the SDT when the target SSB index is determined.

[0050] In some embodiments, a synchronization signal block (SSB) measurement is performed to determine a target SSB index corresponding to a target beam direction, a target repeat transmission occasion (TO) is determined based on the target SSB index, and a small data transmission (SDT) is performed based on the target repeat TO, where the target repeat TO is a TO corresponding to the Nth repeat transmission in the SDT, where N is a positive integer, and the target repeat TO is determined to be N in the TO corresponding to the Nth repeat transmission in the SDT according to protocol specifications, or the target repeat TO is determined to be N in the TO corresponding to the Nth repeat transmission in the SDT according to base station configuration or instruction.

[0051] For example, if the protocol specification determines that the target repeat TO is N (N is 1) in the TO corresponding to the Nth repeat transmission in the SDT, the protocol specification determines that the target repeat TO is the TO corresponding to the first repeat transmission in the SDT, and selects the target repeat TO to perform the first repeat transmission of the SDT.

[0052] For example, if the target repeat TO is determined by the base station setting or instruction to be N (N is 1) in the TO corresponding to the Nth repeat transmission in the SDT, the base station determines by the base station setting or instruction that the target repeat TO is the TO corresponding to the first repeat transmission in the SDT, and selects the target repeat TO to perform the first repeat transmission of the SDT.

[0053] The above examples are merely illustrative and do not specifically limit the embodiments of the present disclosure. The target repeat TO is determined by protocol definition, or by base station configuration or instruction, to be a parameter other than N (N may be 1) in the TO corresponding to the Nth repeat transmission in the SDT.

[0054] In some embodiments, the number of repeat transmissions is M, 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 repeat transmissions M minus one.

[0055] In an exemplary embodiment, as shown in FIG. 3, there are four SSBs in the SSB set (synchronization signal block set) configured by one CG (configured grant), and the number of repeated transmissions M is four. Therefore, the number of TOs can be determined as the number of SSBs (4) plus the number of repeated transmissions (4) minus one, which results in the number of TOs being seven.

[0056] When N is 1, the first four TOs are used for the first repeated transmission in the SDT, and the last three TOs are used for the remaining three repeated transmissions in the SDT, respectively.

[0057] Of course, the example shown in FIG. 3 is illustrative, and in an embodiment of the present disclosure, N may be 3, and the third repeated transmission in the SDT may be associated with a target SSB index, in which case the first TO is used for the first repeated transmission in the SDT, the second TO is used for the second repeated transmission in the SDT, the third, fourth, fifth, and sixth TOs are used for the third repeated transmission in the SDT, and the seventh TO is used for the fourth repeated transmission in the SDT.

[0058] In the embodiment of the present disclosure, N may be set or indicated by the base station; Pre-set It may be indicated by a specific method or by other implicit methods, and is not limited to the embodiments of the present disclosure.

[0059] In some embodiments, the SSB indices associated with the TOs corresponding to the M repeated transmissions are all target SSB indices.

[0060] In an embodiment of the present disclosure, when a target repetition TO is associated with a target SSB index, the target repetition TO of the Nth repeated transmission out of M repeated transmissions may be associated with the target SSB index, and the other repeated transmissions may be associated with the target SSB index.

[0061] In some embodiments, the TO corresponding to the M repeated transmissions constitutes one target physical uplink shared channel occasion PO.

[0062] In an exemplary embodiment, still referring to FIG. 3, there are four SSBs in an SSB set (synchronization signal block set) configured by one CG (configured grant), and the number of repeated transmissions M is four, so the number of TOs can be determined to be the number of SSBs (4) plus the number of repeated transmissions (4) minus 1, resulting in the number of TOs being seven.

[0063] In one example, when N is 1, the first four TOs are used for the first repeat transmission in the SDT, and the last three are used for the remaining three repeat transmissions in the SDT, respectively. The terminal device performs SSB measurements to determine that SSB#2 corresponding to TO#2 has the best signal quality, and the terminal device selects TO#2 to perform the first repeat transmission in the SDT, and then completes the remaining three repeat transmissions using TO#4, TO#5, and TO#6.

[0064] Here, TO#2, TO#4, TO#5 and TO#6 can constitute one target PO.

[0065] Note that TO#4, TO#5 and TO#6, which are occupied by the remaining three repeated transmissions, may be similarly associated with SSB#1.

[0066] In the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute one target PO.

[0067] In another example, when N is 1, the first four TOs are used for the first repeat transmission in the SDT, and the last three are used for the remaining three repeat transmissions in the SDT, respectively. If the terminal device performs SSB measurements and determines that SSB#1 corresponding to TO#1 has the best signal quality, the terminal device selects TO#1 for the first repeat transmission in the SDT, and then uses TO#4, TO#5, and TO#6 to complete the remaining three repeat transmissions.

[0068] Here, TO#1, TO#4, TO#5 and TO#6 can constitute one target PO.

[0069] Note that TO#4, TO#5 and TO#6, which are occupied by the remaining three repeated transmissions, may be similarly associated with SSB#1.

[0070] In the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute one target PO.

[0071] In the above exemplary embodiment of the present disclosure, the number of TOs is determined to be the number of SSBs (4) plus the number of repeated transmissions (4) minus one, so the number of TOs is seven.

[0072] Furthermore, for M repeated transmissions of the SDT, M TOs may correspond to each SSB, and M TOs are used for M repeated transmissions of the SDT. In this case, if there are K SSBs in an SSB burst, the number of TOs that need to be set is K*M, where K and M are both positive integers.

[0073] However, in the embodiment of the present disclosure, the number of TOs that need to be set is the number of SSBs K plus the number of repeated transmissions M minus 1, which is enough to realize M repeated transmissions of SDT, thereby significantly saving time-frequency resources and improving spectral efficiency.

[0074] In some embodiments, one configuration authorization period of the SDT includes multiple POs, and the redundancy version (RV) sequence corresponding to the TO in the target PO is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}, and the RV corresponding to the TO in other POs among the multiple POs other than the target PO is RV0.

[0075] In an embodiment of the present disclosure, a terminal device performs synchronization signal block (SSB) measurement to determine a target SSB index corresponding to a target beam direction, determines a repeat transmission occasion (TO) based on the target SSB index, and performs a small data transmission (SDT) based on the target repeat TO, where the target repeat TO is a TO corresponding to the Nth repeat transmission in the SDT, where N is a positive integer, thereby realizing the repeat transmission of the configured authorized CG-SDT, while significantly saving time-frequency resources and improving spectral efficiency.

[0076] Please refer to FIG. 4, which is a flowchart of another method for determining time domain resource transmission positions provided by an embodiment of the present disclosure.

[0077] As shown in FIG. 4, the method is applied to a terminal device, and may include the following steps 41 to 42.

[0078] S41, perform synchronization signal block (SSB) measurements to determine a target SSB index corresponding to the target beam direction.

[0079] In the embodiment of the present disclosure, for the explanation related to S41, please refer to the explanation related to S21 in the above example, and detailed explanation will be omitted here.

[0080] S42: Determine a target repeat transmission occasion (TO) based on the target SSB index, and perform a small data transmission (SDT) based on the target repeat TO, where the target repeat TO is a TO corresponding to an Nth repeat transmission in the SDT, where N is a positive integer. The SDT includes multiple configured authorization periods, each configured authorization period includes one PO, one configured authorization period of the multiple configured authorization periods has multiple TOs used for the repeat transmission, and another configured authorization period of the multiple configured authorization periods has one TO used for the repeat transmission.

[0081] In some embodiments, the Lth repeat transmission corresponding to the TO used for the repeat transmission in another configured grant period is Pre-set or set or indicated by the base station, where L is a positive integer.

[0082] In addition, in other configured authorization periods, one configured authorization period has one TO used for repeated transmission, and the only TO may be any one next repeated transmission. In the embodiment of the present disclosure, the Lth repeated transmission corresponding to one TO used for repeated transmission included in one configured authorization period among the other configured authorization periods is Pre-set Alternatively, it may be set or instructed by the base station.

[0083] In an embodiment of the present disclosure, different SSBs are associated with different configuration authorization periods, and one of the multiple configuration authorization periods has multiple TOs used for repeated transmission, and the number of the configuration authorization period among the multiple configuration authorization periods that one of the multiple TOs used for repeated transmission belongs to can be determined by base station configuration or instruction.

[0084] In some embodiments, multiple configured grant periods use the same hybrid automatic repeat request (HARQ) process number (HPN).

[0085] In an exemplary embodiment, the terminal device determines a target SSB index by performing SSB measurements, and the target SSB index corresponds to a target beam direction, where the signal quality of the target beam is the best. As shown in Figure 5, the SDT includes four CG periods (configuration grant periods), one CG period includes one PO, CG period #4 of the four CG periods has four TOs used for repeated transmission, and CG period #1, CG period #2, and CG period #3 of the four CG periods have one TO used for repeated transmission.

[0086] In one example, the terminal device performs SSB measurements to determine the optimum beam for CG period #2. st It is determined that the first repetition transmission is to be performed in the repetition resource, and at the same time, the remaining repetitions are transmitted in the resources configured for non-first repetition. For example, if the number of repetitions is four, the second repetition of CG period #4 is determined. nd The second repetition transmission is performed in the repetition resource, and the 3rd repetition of CG cycle #4 is performed. rd The third repetition transmission is performed in the repetition resource, and the fourth CG cycle is th The fourth repetition transmission is performed in the repetition resource.

[0087] In addition, the base station can determine the configured authorization period in which different repeated transmission numbers are located by setting it, and the base station can set the configured authorization period in which different repeated transmission numbers are located by using a method such as a bitmap or code point.

[0088] In some embodiments, the redundancy version (RV) sequence corresponding to one of the multiple configured authorization periods having multiple TOs used for repeated transmission is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}, and the RV corresponding to one of the multiple configured authorization periods having one TO used for repeated transmission is RV0.

[0089] In the embodiments of the present disclosure, the above S41 and S42 may be implemented alone or together with any other embodiment of the present disclosure, for example, together with S21 and S22 in the present disclosure, but are not limited to the embodiments of the present disclosure.

[0090] Please refer to FIG. 6, which is a flowchart of another method for determining time domain resource transmission positions provided by an embodiment of the present disclosure.

[0091] As shown in FIG. 6, the method is applied to a base station, and the method may include, but is not limited to, the following steps S61 to S62.

[0092] S61, receive an SDT of a terminal device, and determine a target repetition TO, where the target repetition TO is a TO corresponding to an Nth repetition transmission in the SDT, where N is a positive integer.

[0093] In an embodiment of the present disclosure, the terminal device determines a target SSB index through SSB (Synchronization signal and PBCH block) measurement, where the target SSB index corresponds to the target beam direction, the target beam is an optimal beam, and the target SSB index corresponds to the optimal beam direction, and based on this, determines an optimal beam transmission SDT, whereby the base station can receive the SDT of the terminal device and determine a target repetition TO, where the target repetition TO is a TO corresponding to the Nth repeated transmission in the SDT, and N is a positive integer.

[0094] In addition, in the embodiment of the present disclosure, the target SSB index corresponds to the target beam direction, and the target beam may be a beam other than the optimal beam, and is not limited to this in the embodiment of the present disclosure.

[0095] S62, based on the target repetition TO, determine a target SSB index corresponding to the target beam direction.

[0096] In some embodiments, the base station sets or indicates that the target repeated TO is N in the TO corresponding to the Nth repeated transmission in the SDT.

[0097] In an embodiment of the present disclosure, each of the multiple SSBs in an SSB burst corresponds to a TO corresponding to the Nth repeated transmission in the SDT, and by measuring the multiple SSBs in the SSB burst, one SSB with high channel quality is selected as the target SSB, and based on the target SSB, the TO corresponding to the Nth repeated transmission in the corresponding SDT is determined, and the TO corresponding to the Nth repeated transmission in the SDT is determined to be the target repeated TO.

[0098] In the embodiment of the present disclosure, after determining the target repetition TO, the terminal device can perform SDT based on the target repetition TO.

[0099] In addition, in an embodiment of the present disclosure, other repeated transmissions in the SDT than the Nth repeated transmission may be associated with the target SSB of the target SSB index, thereby determining all repeated transmissions in the SDT when the target SSB index is determined.

[0100] In some embodiments, the number of repeat transmissions is M, 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 repeat transmissions M minus one.

[0101] In an exemplary embodiment, as shown in FIG. 3, there are four SSBs in the SSB set (synchronization signal block set) configured by one CG (configured grant), and the number of repeated transmissions M is four. Therefore, the number of TOs can be determined as the number of SSBs (4) plus the number of repeated transmissions (4) minus one, which results in the number of TOs being seven.

[0102] When N is 1, the first four TOs are used for the first repeated transmission in the SDT, and the last three TOs are used for the remaining three repeated transmissions in the SDT, respectively.

[0103] Of course, the example shown in FIG. 3 is merely illustrative, and in an embodiment of the present disclosure, N may be 3, and the third repeated transmission in the SDT may be associated with a target SSB index, in which case the first TO is used for the first repeated transmission in the SDT, the second TO is used for the second repeated transmission in the SDT, the third, fourth, fifth, and sixth TOs are used for the third repeated transmission in the SDT, and the seventh TO is used for the fourth repeated transmission in the SDT.

[0104] In some embodiments, the SSB indices associated with the TOs corresponding to the M repeated transmissions are all target SSB indices.

[0105] In an embodiment of the present disclosure, when a target repetition TO is associated with a target SSB index, the target repetition TO of the Nth repeated transmission out of M repeated transmissions may be associated with the target SSB index, and the other repeated transmissions may be associated with the target SSB index.

[0106] In some embodiments, the TO corresponding to the M repeated transmissions constitutes one target physical uplink shared channel occasion PO.

[0107] In an exemplary embodiment, still referring to FIG. 3, there are four SSBs in an SSB set (synchronization signal block set) configured by one CG (configured grant), and the number of repeated transmissions M is four, so that the number of TOs can be determined as the number of SSBs (4) plus the number of repeated transmissions (4) minus one, resulting in the number of TOs being seven.

[0108] In one example, when N is 1, the first four TOs are used for the first repeat transmission in the SDT, and the last three are used for the remaining three repeat transmissions in the SDT, respectively. The terminal device performs SSB measurements to determine that SSB#2 corresponding to TO#2 has the best signal quality, and the terminal device selects TO#2 to perform the first repeat transmission in the SDT, and then completes the remaining three repeat transmissions using TO#4, TO#5, and TO#6.

[0109] Here, TO#2, TO#4, TO#5 and TO#6 can constitute one target PO.

[0110] Note that TO#4, TO#5 and TO#6, which are occupied by the remaining three repeated transmissions, may be similarly associated with SSB#1.

[0111] In the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute one target PO.

[0112] In another example, when N is 1, the first four TOs are used for the first repeat transmission in the SDT, and the last three are used for the remaining three repeat transmissions in the SDT, respectively. If the terminal device performs SSB measurements and determines that SSB#1 corresponding to TO#1 has the best signal quality, the terminal device selects TO#1 for the first repeat transmission in the SDT, and then uses TO#4, TO#5, and TO#6 to complete the remaining three repeat transmissions.

[0113] Here, TO#1, TO#4, TO#5 and TO#6 can constitute one target PO.

[0114] Note that TO#4, TO#5 and TO#6, which are occupied by the remaining three repeated transmissions, may be similarly associated with SSB#1.

[0115] In the embodiment of the present disclosure, TO#0, TO#1, TO#2, TO#3, TO#4, TO#5 and TO#6 can constitute one target PO.

[0116] In the above exemplary embodiment of the present disclosure, the number of TOs is determined to be the number of SSBs (4) plus the number of repeated transmissions (4) minus one, so the number of TOs is seven.

[0117] Furthermore, for M repeated transmissions of the SDT, M TOs may correspond to each SSB, and M TOs are used for M repeated transmissions of the SDT. In this case, if there are K SSBs in an SSB burst, the number of TOs that need to be set is K*M, where K and M are both positive integers.

[0118] However, in the embodiment of the present disclosure, the number of TOs that need to be set is the number of SSBs K plus the number of repeated transmissions M minus 1, which is enough to realize M repeated transmissions of SDT, thereby significantly saving time-frequency resources and improving spectral efficiency.

[0119] In some embodiments, one configuration authorization period of the SDT includes multiple POs, and the redundancy version (RV) sequence corresponding to the TO in the target PO is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}, and the RV corresponding to the TO in other POs among the multiple POs other than the target PO is RV0.

[0120] By implementing the embodiment of the present disclosure, a base station receives an SDT from a terminal device, determines a target repetition TO, where the target repetition TO is a TO corresponding to the Nth repeated transmission in the SDT, where N is a positive integer, and determines a target SSB index corresponding to the target beam direction based on the target repetition TO, thereby realizing repeated transmission of the configured authorized CG-SDT, greatly saving time-frequency resources and improving spectral efficiency.

[0121] For detailed descriptions of the embodiments S61 and S62 of the present disclosure, please refer to the relevant descriptions of the above embodiments of the present disclosure, and detailed descriptions will be omitted here.

[0122] By implementing the embodiments of the present disclosure, repeated transmission of the configuration authorization CG-SDT can be realized.

[0123] Please refer to FIG. 7, which is a flowchart of another method for determining time domain resource transmission positions provided by an embodiment of the present disclosure.

[0124] As shown in FIG. 7, the method is applied to a base station, and the method may include, but is not limited to, the following steps S71 to S72.

[0125] S71: receiving an SDT of a terminal device; and determining a target repetition TO, where the target repetition TO is a TO corresponding to an Nth repetition transmission in the SDT, where N is a positive integer; the SDT includes multiple configuration authorization periods, each configuration authorization period includes one PO; one configuration authorization period among the multiple configuration authorization periods has multiple TOs used for the repetition transmission; and another configuration authorization period among the multiple configuration authorization periods has one TO used for the repetition transmission.

[0126] S72, based on the target repetition TO, determine a target SSB index corresponding to the target beam direction.

[0127] In some embodiments, the base station configures or indicates L for the Lth repeated transmission corresponding to the TO used for the repeated transmission in another configured grant period, where L is a positive integer.

[0128] In some embodiments, multiple configured grant periods use the same hybrid automatic repeat request process number (HPN).

[0129] In some embodiments, the redundancy version (RV) sequence corresponding to one of the multiple configured authorization periods having multiple TOs used for repeated transmission is {0,0,0,0}, or {0,3,0,3}, or {0,2,3,1}, and the RV corresponding to one of the multiple configured authorization periods having one TO used for repeated transmission is RV0.

[0130] For detailed descriptions of the embodiments S71 and S72 of the present disclosure, please refer to the relevant descriptions of the above embodiments of the present disclosure, and detailed descriptions will be omitted here.

[0131] In the embodiments of the present disclosure, the above steps S71 and S72 may be implemented alone or together with any other embodiment of the present disclosure. For example, in the present disclosure, steps S61 and S62 may be implemented together. Carried out However, the embodiments of the present disclosure are not specifically limited.

[0132] Please refer to FIG. 8, which is a flowchart of another method for determining time domain resource transmission positions provided by an embodiment of the present disclosure.

[0133] As shown in FIG. 8, the method is applied to a base station, and the method may include, but is not limited to, the following steps S81 to S82.

[0134] S81: Receive an SDT of a terminal device, and determine a target repetition TO, where the target repetition TO is a TO corresponding to the Nth repeated transmission in the SDT, where N is a positive integer, and the step of determining the target repetition TO includes: performing energy detection on multiple TOs at the time of the Nth repeated transmission; and determining a target repetition TO at the time of the Nth repeated transmission based on the energy detection results of the multiple TOs.

[0135] S82, based on the target repetition TO, determine a target SSB index corresponding to the target beam direction.

[0136] In an embodiment of the present disclosure, a base station receives an SDT from a terminal device, and when the SDT is repeated for the Nth time, the base station performs energy detection in multiple TOs, illustratively performing RSRP measurement for DMRS. The base station can determine in which TO the Nth repeated transmission was sent by measuring and obtaining the highest signal quality, thereby obtaining related information about the SSB index. Then, when the terminal device performs the repeated SDT, it can receive in the target beam direction corresponding to the same SSB index.

[0137] In some embodiments, the base station indicates to the terminal device the time interval gap between TOs repeatedly transmitted by multiple users.

[0138] In an embodiment of the present disclosure, a base station indicates to a terminal device the time interval gap between TOs repeatedly transmitted by multiple users, so that the terminal device can repeat two adjacent SDTs at the indicated time interval gap. Therefore, when measuring the previous SDT in the time interval gap, the base station can determine in which TO the previous SDT repeated transmission was transmitted based on the energy of multiple TOs, thereby obtaining related information about the SSB index. Thereafter, when the terminal device performs the repeated SDT, it will receive in the target beam direction corresponding to the same SSB index, thereby effectively saving time domain resources.

[0139] In the embodiments of the present disclosure, S81 and S82 may be implemented alone or together with any other embodiment of the present disclosure, for example, S61 and S62 and / or S71 and S72 of the present disclosure, and are not specifically limited in the embodiments of the present disclosure.
