[0029] To facilitate understanding of the present disclosure, we now introduce a simplified version of 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 there are multiple transmission occasions and the multiple transmission occasions are used for repeated transmission, multiple identical data are repeatedly transmitted in the multiple transmission occasions. At this time, 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] In order to better understand the method and apparatus for determining time domain resource transmission position 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 an architecture schematic diagram of a communication system provided by an embodiment of the present disclosure.

[0036] It should be noted that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not limit the technical solutions provided by the embodiments of the present disclosure. As those skilled in the art can understand, 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 be similarly applied to similar technical problems.

[0037] For 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. In this manner, the optimal downlink beam can be implicitly reported to the base station.

[0038] The method and apparatus for determining time domain resource transmission position 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 21-22.

[0041] S21, perform synchronization signal block (SSB) measurement to determine a 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 through SSB (Synchronization signal and PBCH block) measurement, 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 embodiments 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 the embodiments of the present disclosure.

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

[0045] Exemplarily, 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 an 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, a TO corresponding to a number of repeated transmissions other than the Nth repeated transmission may be associated with a target SSB of a 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 repeated transmission occasion (TO) is determined based on the target SSB index, and a small data transmission (SDT) is performed based on the target repeated TO, where the target repeated TO is a TO corresponding to an Nth repeated transmission in the SDT, where N is a positive integer, and the target repeated TO is determined to be N in the TO corresponding to the Nth repeated transmission in the SDT according to protocol specifications, or the target repeated TO is determined to be N in the TO corresponding to the Nth repeated transmission in the SDT according to base station configuration or instruction.

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

[0052] For example, when 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 repeated transmission in the SDT, the target repeat TO is determined by the base station setting or instruction to be the TO corresponding to the first repeated transmission in the SDT, and the target repeat TO is selected to perform the first repeated transmission of the SDT.

[0053] It should be noted that the above examples are merely illustrative and do not specifically limit the embodiments of the present disclosure. According to protocol specifications, or according to base station settings or instructions, the target repeat TO is determined 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 repeated 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 repeated transmissions M minus 1.

[0055] In an exemplary embodiment, as shown in FIG. 3, there are four SSBs in an SSB set configured by one CG (configured grant), and the number of repeated transmissions M is four. Thus, 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 obtained as 7.

[0056] 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.

[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 repeat transmission in the SDT may be associated with a target SSB index, in which case the first TO is used for the first repeat transmission in the SDT, the second TO is used for the second repeat transmission in the SDT, the third, fourth, fifth and sixth TOs are used for the third repeat transmission in the SDT, and the seventh TO is used for the fourth repeat transmission in the SDT.

[0058] In the embodiment of the present disclosure, N may be set or indicated by the base station; Pre-set The present disclosure is not limited to the embodiments described above, but may be directed to the specific embodiment or may be indicated in other implicit manners.

[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 an 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 configured by one CG (configured grant), and the number of repeated transmissions M is four, so that 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 determines that the signal quality of SSB#2 corresponding to TO#2 is the best by performing SSB measurement, and the terminal device selects TO#2 to perform the first repeat transmission in the SDT, and then uses TO#4, TO#5 and TO#6 to complete the remaining three repeat transmissions.

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

[0065] It should be noted 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 addition, 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. The terminal device performs SSB measurement to determine that the signal quality of SSB#1 corresponding to TO#1 is the best, so the terminal device selects TO#1 to perform 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] It should be noted 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 addition, 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 1, so the number of TOs is 7.

[0072] In addition, for M repeated transmissions of the SDT, M TOs may correspond to each SSB, and the M TOs are used for the 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 needs to be set is the number K of SSBs plus the number M of repeated transmissions minus 1, which is enough to realize M repeated transmissions of SDT, thereby greatly 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] By implementing the 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) according to the target SSB index, and performs a small data transmission (SDT) according to the target repeat TO, where the target repeat TO is a TO corresponding to an N-th repeat transmission in the SDT, where N is a positive integer, thereby realizing the repeat transmission of the configured authorization CG-SDT, while greatly saving time-frequency resources and improving spectrum efficiency.

[0076] Please refer to FIG. 4, which is a flowchart of another time domain resource transmission position determination method 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 41-42.

[0078] S41, perform synchronization signal block (SSB) measurement 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 N-th repeat transmission in the SDT, where N is a positive integer. The SDT includes multiple configured authorization periods, one 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 is set or indicated by the base station, where L is a positive integer.

[0082] In addition, in the 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 indicated 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 of one of the multiple TOs used for repeated transmission can be determined by a 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 measurement, 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 authorization 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 first beam of CG period #2 that corresponds to the optimal beam. st It is determined to transmit the first repetition in the repetition resource, and at the same time, transmit the remaining repetitions in the resources set to 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 third CG cycle #4 is performed. rd The third repetition transmission is performed in the repetition resource, and the fourth CG cycle #4 is performed. th The fourth repetition transmission is performed in the repetition resource.

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

[0088] In some embodiments, a 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 an RV corresponding to one of the multiple configured authorization periods having one TO used for repeated transmission is RV0.

[0089] In addition, in the embodiment 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, they are implemented together with S21 and S22 in the present disclosure, and are not limited to the embodiment of the present disclosure.

[0090] Please refer to FIG. 6, which is a flowchart of another time domain resource transmission position determination method 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 N-th 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 a 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 embodiments 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 the embodiments 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 an 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 repeated 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 repeated transmissions M minus 1.

[0101] In an exemplary embodiment, as shown in FIG. 3, there are four SSBs in an SSB 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 to be the number of SSBs (4) plus the number of repeated transmissions (4) minus 1, and the number of TOs is obtained to be seven.

[0102] When N is 1, the first four TOs are used for the transmission of the first repeat transmission in the SDT, and the last three are used for the remaining three repeat 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 repeat transmission in the SDT may be associated with a target SSB index, in which case the first TO is used for the first repeat transmission in the SDT, the second TO is used for the second repeat transmission in the SDT, the third, fourth, fifth and sixth TOs are used for the third repeat transmission in the SDT, and the seventh TO is used for the fourth repeat 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 an 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 configured by one CG (configured grant), and the number of repeated transmissions M is four, so that 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.

[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 determines that the signal quality of SSB#2 corresponding to TO#2 is the best by performing SSB measurement, and the terminal device selects TO#2 to perform the first repeat transmission in the SDT, and then uses TO#4, TO#5 and TO#6 to complete the remaining three repeat transmissions.

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

[0110] It should be noted 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 addition, 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. The terminal device performs SSB measurement to determine that the signal quality of SSB#1 corresponding to TO#1 is the best, so the terminal device selects TO#1 to perform 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] It should be noted 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 addition, 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 1, so the number of TOs is 7.

[0117] In addition, for M repeated transmissions of the SDT, M TOs may correspond to each SSB, and the M TOs are used for the 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 needs to be set is the number K of SSBs plus the number M of repeated transmissions minus 1, which is enough to realize M repeated transmissions of SDT, thereby greatly 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] Implementing the embodiment of the present disclosure, receiving the SDT of the base station terminal device, determining a target repetition TO, where the target repetition TO is a TO corresponding to the Nth repetition transmission in the SDT, where N is a positive integer, and determining a target SSB index corresponding to a target beam direction according to the target repetition TO, thereby realizing the repetition transmission of the configured authorization CG-SDT, greatly saving time-frequency resources and improving spectrum efficiency.

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

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

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

[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: receiving an SDT of a terminal device, and determining a target repetition TO, the target repetition TO being a TO corresponding to an N-th repeated transmission in the SDT, where N is a positive integer, and the step of determining the target repetition TO includes the steps of: performing energy detection in multiple TOs at the time of the N-th repeated transmission; and determining a target repetition TO at the time of the N-th 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 of a terminal device, and when performing the SDT repeatedly for the Nth time, the base station performs energy detection in multiple TOs, illustratively performing RSRP measurement for a DMRS, and the base station can determine in which TO the Nth repeated transmission is transmitted by measuring and obtaining the highest signal quality, thereby obtaining related information of the SSB index, and 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 the embodiment of the present disclosure, the base station indicates to the terminal device the time interval gap between the TOs repeatedly transmitted by multiple users, so that the terminal device can repeat two adjacent SDTs at the indicated time interval gap. Therefore, when the base station measures the previous SDT in the time interval gap, it can determine in which TO the previous SDT repeated transmission is transmitted based on the energy of multiple TOs, so as to obtain the relevant information of the SSB index. Then, when the terminal device performs the repeated SDT, it will receive in the target beam direction corresponding to the same SSB index, so as to effectively save the time domain resource.
