[0001] This application relates to the field of communication technology, and in particular to a communication method, communication device, readable storage medium, and computer program product. Background Technology

[0002] As human demand for communication coverage continues to increase, the coverage of various physical channels in current mobile communication systems needs further enhancement. For example, in non-terrestrial networks (NTN) communication systems, satellites can provide a large coverage area. However, due to the long distance between satellites and terminal devices, path loss is significant, and satellite capabilities are limited (e.g., limited satellite transmission power, limited satellite antenna area, etc.). Therefore, the physical signal or physical signal between terminal devices and satellites needs coverage enhancement to ensure reliable communication between them. Summary of the Invention

[0057] As described in the background section, the coverage of the physical channels transmitted by network devices in mobile communication systems needs to be enhanced. Since the Physical Downlink Control Channel (PDCCH) is used to carry control signaling, enhancing the coverage of the PDCCH is particularly important for ensuring communication quality.

[0058] In view of this, this application provides a communication method. In the scheme of this application embodiment, the terminal device determines whether the PDCCH repetition condition is met. If the PDCCH repetition condition is met, the terminal device listens to the PDCCH at N PDCCH listening times associated with the Synchronization Signal Block (SSB), where the SSB is an SSB with signal quality greater than or equal to a threshold, and N is a positive integer greater than 1.

[0059] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

For ease of description, the embodiments provided in this application will be illustrated using network devices and terminal devices as examples of the executing entities.

[0060] Example 1

[0061] Reference Figure 1 , Figure 1 This is a flowchart illustrating the first communication method in an embodiment of this application. For example... Figure 1 As shown, Figure 1 The methods shown may include S11, S12, and S13.

[0062] S11, The terminal device determines the SSB;

[0063] S12, the terminal device determines the time slots where the N PDCCH listening opportunities are located based on the index of the SSB, where the N PDCCH listening opportunities are located in the same time slot and N is a positive integer greater than 1;

[0064] S13, the terminal device determines the listening time of N PDCCH associated with SSB.

[0065] In S11, the terminal device can measure multiple SSBs of the current cell to obtain the signal quality of the multiple SSBs, wherein the current cell is the cell in which the terminal device receives System Information Block 1 (SIB1). Further, the terminal device can determine one SSB from the multiple SSBs based on the signal quality of each SSB. For example, the signal quality of the SSB determined by the terminal device is greater than or equal to a threshold.

[0066] In S12, the terminal device can determine the time slot number of the N PDCCH listening opportunities based on the SSB index determined in S11. In other words, the terminal device can determine the time slot where the PDCCH is repeatedly transmitted based on the SSB index.

[0067] In one possible implementation, the slot number n0 of the slot where the N PDCCH listening opportunities are located can be determined by equation (1):

[0068]

[0069] Where O is the group offset, μ is the subcarrier spacing, i is the SSB index, and M is the scaling factor. This represents the number of time slots contained in a single system frame when the subcarrier spacing is μ.

[0070] In practical implementation, the terminal device can first determine whether the PDCCH repetition condition is met. If the PDCCH repetition condition is met, the terminal device can determine that the PDCCH will be retransmitted. Specifically, if the PDCCH repetition condition is met, the terminal device can execute S12 to determine the time slots where the N PDCCH listening opportunities are located. If the PDCCH repetition condition is not met, the terminal device can determine that the PDCCH will not be retransmitted.

[0071] If the terminal device determines that the PDCCH repetition condition is not met, or if the terminal device determines that the PDCCH is not retransmitted, then the terminal device can use equation (2) to determine the time slot n0 where the PDCCH listening opportunity is located, and then use the single PDCCH listening opportunity in time slot n0 as the single listening opportunity associated with SSB.

[0072]

[0073] Where O is the group offset, μ is the subcarrier spacing, i is the SSB index, and M is the scaling factor. This represents the number of time slots contained in a single system frame when the subcarrier spacing is μ.

[0074] One possible implementation of "listening to PDCCH during the N PDCCH listening times associated with SSB in response to the PDCCH repetition condition being met" is as follows: upon receiving a fifth indication message that indicates PDCCH repetition, the PDCCH is listened to during the N PDCCH listening times associated with SSB.

[0075] In practice, the fifth indication information can be carried in the Master Information Block (MIB), but is not limited to this. For example, the fifth indication information can be carried in the physical layer bit half-frame-index or physical layer bit within the MIB. and physical layer bits At least one of them.

[0076] Another possible implementation of "listening to the PDCCH during the N PDCCH listening times associated with the SSB in response to the PDCCH repetition condition being met" is as follows: If the sixth indication information, which indicates that the first downlink control information should not be retransmitted, is not received, then the PDCCH will be listened to during the N PDCCH listening times associated with the SSB. In other words, if the terminal device receives the sixth indication information, the terminal device can listen to the PDCCH during a single PDCCH listening time associated with the SSB. The sixth indication information can be used to indicate that the PDCCH transmission is a single transmission. In other words, the sixth indication information can be used to indicate that the repetition of PDCCH transmission is disabled.

[0077] In practical implementation, the sixth indication information can be carried in the MIB. For example, the sixth indication information can be carried in the physical layer bit half-frame-index or physical layer bit within the MIB. and physical layer bits At least one of them.

[0078] In one example, the physical layer bit half-frame-index in the MIB is set to 1, indicating that the PDCCH is transmitted repeatedly. The physical layer bit half-frame-index in the MIB is set to 0, indicating that the PDCCH is not transmitted repeatedly.

[0079] In another example, physical layer bits in the MIB A value of 1 indicates that the PDCCH is transmitted repeatedly. Physical layer bits in the MIB. A value of 0 indicates that the PDCCH is not transmitted repeatedly.

[0080] In yet another example, the physical layer bits in the MIB A value of 1 indicates that the PDCCH is transmitted repeatedly. Physical layer bits in the MIB. A value of 0 indicates that the PDCCH is not transmitted repeatedly.

[0081] In S13, the listening times of N PDCCH associated with SSB can be determined in the time slot determined in S12.

[0082] In the scheme of this application embodiment, the N PDCCH listening times associated with the SSB are used to receive N repeated transmissions of the first downlink control information. In other words, the first downlink control information transmitted in the N PDCCH listening times is the same information.

[0083] For example, N=2. Specifically, the two PDCCH listening times associated with the SSB are PDCCH listening time 1 and PDCCH listening time 2. The first downlink control information transmitted in PDCCH listening time 1 and the first downlink control information transmitted in PDCCH listening time 2 are the same.

[0084] The first downlink control information can be information carried on the PDCCH in existing communication protocols. For example, the first downlink control information can be information used to schedule System Information Block 1 (SIB1). It should be noted that the first downlink control information can also be information carried on the PDCCH in future communication protocols, and this application embodiment does not limit this.

[0085] In the scheme of Embodiment 1, each time slot may include N search space sets, that is, each time slot contains N PDCCH listening opportunities. In other words, M = 1 / N, where M represents the scaling factor. In S13, the terminal device can use all the PDCCH listening opportunities in the time slots determined in S12 as PDCCH listening opportunities associated with the SSB, thereby obtaining N PDCCH listening opportunities associated with the SSB. That is to say, in the scheme of Embodiment 1, multiple PDCCH listening opportunities in the same time slot are associated with the same SSB, and multiple PDCCH listening opportunities in the same time slot are used for repeated PDCCH transmission, rather than different PDCCH listening opportunities in the same time slot being associated with different SSBs.

[0086] It should be noted that "PDCCH repeated transmission" in this article can be understood as "repeated transmission of the first downlink control information".

[0087] It should also be noted that after determining the time slots where the N PDCCH listening opportunities are located in S12, existing technologies can be used to determine the PDCCH listening opportunities located in that time slot, and this embodiment does not limit this.

[0088] As described above, in the scheme of Embodiment 1, each time slot contains N PDCCH listening opportunities. If the PDCCH repetition condition is met, the terminal device determines an SSB and a time slot based on the index of the SSB. Then, the N PDCCH listening opportunities in that time slot are considered as the N PDCCH listening opportunities associated with that SSB. That is, in the scheme of Embodiment 1, the N PDCCH listening opportunities in the same time slot are used for N repeated transmissions of PDCCH. The terminal device receives the first downlink control information transmitted N times repeatedly on multiple PDCCH listening opportunities in a single time slot and performs merging and decoding, thereby achieving PDCCH coverage enhancement.

[0089] For more details on Embodiment 1, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0090] Example 2

[0091] Reference Figure 2 , Figure 2 This is a flowchart illustrating the second communication method in an embodiment of this application. For example... Figure 2 As shown, Figure 2 The methods shown may include S21, S22 and S23.

[0092] S21, The terminal device determines the SSB;

[0093] S22, The terminal device determines N consecutive time slots;

[0094] S23, the terminal device determines the N PDCCH listening opportunities associated with the SSB in N consecutive time slots, wherein the N PDCCH listening opportunities are located on N time slots respectively, and the time slots of different PDCCH listening opportunities are different.

[0095] For details regarding S21, please refer to the above description of S11; it will not be repeated here.

[0096] In S22, the terminal device can determine the first time slot at least according to the index of the SSB determined in S11. For example, the terminal device can determine the time slot number n0 of the first time slot according to equation (2) above.

[0097] Furthermore, the terminal device can determine that the N consecutive time slots starting from the first time slot are the time slots where the PDCCH listening opportunity occurs. That is, the first time slot among the N consecutive time slots is the first time slot. Thus, in S22, the terminal device can determine the N consecutive time slots. Each of the N consecutive time slots contains a single PDCCH listening opportunity. For example, if the time slot number of the first time slot is n0, then the time slot numbers of the (N-1) consecutive time slots after the first time slot are n0+1, n0+2, ..., n0+N-1, respectively. In other words, in the scheme of Embodiment 2, there is a 0-time-slot interval between any two adjacent time slots among the N time slots where the PDCCH listening opportunity occurs.

[0098] Furthermore, in S23, the terminal device determines the PDCCH listening time in each of the N consecutive time slots. The terminal device can use all the PDCCH listening times in the N consecutive time slots as the PDCCH listening times associated with the SSB.

[0099] In one example, N = 2. One of the two PDCCH listening opportunities associated with the SSB is located in the first time slot, and the other is located in the second time slot, which is the next time slot after the first time slot.

[0100] Before S22, the terminal device can first determine whether the PDCCH repetition condition is met. If the PDCCH repetition condition is met, the terminal device determines that the PDCCH will be retransmitted and determines the N PDCCH listening opportunities associated with the SSB in N consecutive time slots (such as the first time slot and the second time slot). If the PDCCH repetition condition is not met, the terminal device determines that the PDCCH will not be retransmitted.

[0101] For details on determining whether the PDCCH repeat condition is met, please refer to the relevant descriptions in other embodiments of this document, which will not be repeated here.

[0102] It should be noted that in the scheme of this embodiment, after determining N consecutive time slots, the PDCCH listening time in each time slot can be determined using existing technology, and this embodiment does not limit this.

[0103] Therefore, in the scheme of Embodiment 2, the PDCCH listening time in multiple consecutive time slots is used for repeated transmission of PDCCH. The terminal device repeatedly receives the first downlink control information and performs merging and decoding during the PDCCH listening time in multiple consecutive time slots, thereby achieving PDCCH coverage enhancement.

[0104] For more details on Embodiment 2, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0105] Example 3

[0106] Reference Figure 3 , Figure 3 This is a flowchart illustrating the third communication method in an embodiment of this application. For example... Figure 3 As shown, Figure 3 The methods shown may include S31, S32, and S33.

[0107] S31, The terminal device determines the SSB;

[0108] S32, The terminal device determines N time slots;

[0109] S33, the terminal device determines the N PDCCH listening opportunities associated with the SSB in N time slots, wherein the N PDCCH listening opportunities are located in N time slots respectively, and the time slots of different PDCCH listening opportunities are different.

[0110] For details regarding S31, please refer to the above description of S11; it will not be repeated here.

[0111] In S32, the terminal device can first determine the first time slot, and then determine (N-1) time slots sequentially based on the first time slot and the time slot interval. The specific details regarding the first time slot can be found in the relevant description above, and will not be repeated here.

[0112] In this embodiment, "slot interval" refers to the interval between two adjacent PDCCH listening times within N PDCCH listening times. The slot interval can also be called "slot offset." In specific implementations, the specific value of the slot offset can be defined by the protocol, or it can be configured by the network device.

[0113] Specifically, the first time slot can be the first time slot out of N time slots. In other words, the first time slot is the time slot containing the first PDCCH listening opportunity among the N PDCCH listening opportunities associated with the SSB. Based on the first time slot and the time slot interval, the time slot containing the second PDCCH listening opportunity among the N PDCCH listening opportunities can be determined. Further, based on the time slot containing the second PDCCH listening opportunity among the N PDCCH listening opportunities and the time slot interval, the time slot containing the third PDCCH listening opportunity among the N PDCCH listening opportunities can be determined, and so on, until the N time slots containing the N PDCCH listening opportunities are determined.

[0114] Furthermore, each of the N time slots contains a single PDCCH listening opportunity. The terminal device can determine a PDCCH listening opportunity in the first time slot, which is the first PDCCH listening opportunity associated with the SSB. Furthermore, the terminal device can determine (N-1) other PDCCH listening opportunities associated with the SSB, excluding the first PDCCH listening opportunity, based on the time slot interval.

[0115] In one example, N = 2, where one of the two PDCCH listening opportunities associated with the SSB is located in the first time slot, and the other is located in the third time slot. The time slot number of the first time slot is n0, then the time slot number of the third time slot is n0 + m, or n0 - m, where m is the time slot interval and m is a positive integer. Further, in S33, the terminal device can use both a PDCCH listening opportunity in the first time slot and a PDCCH listening opportunity in the third time slot as PDCCH listening opportunities associated with the SSB.

[0116] Before S32, the terminal device can first determine whether the PDCCH repetition condition is met. If the PDCCH repetition condition is met, the terminal device determines the listening time of N PDCCH associated with the SSB in N time slots. If the PDCCH repetition condition is not met, the terminal device can determine that the PDCCH will not be transmitted repeatedly.

[0117] For details on determining whether the PDCCH repeat condition is met, please refer to the relevant descriptions in other embodiments of this document, which will not be repeated here.

[0118] It should be noted that in the scheme of this embodiment, the PDCCH listening time in each time slot can be determined by existing technology or the PDCCH listening time in the first time slot can be determined by existing technology. This embodiment does not limit this.

[0119] Therefore, in the scheme of Embodiment 3, the PDCCH listening opportunities in multiple time slots are used for repeated PDCCH transmission. The terminal device determines N PDCCH listening opportunities for repeated PDCCH transmission based on the time slot interval. The terminal device repeatedly receives the first downlink control information and performs merging and decoding during the PDCCH listening opportunities in multiple time slots, thereby achieving PDCCH coverage enhancement.

[0121] Example 4

[0122] Reference Figure 4 , Figure 4This is a flowchart illustrating the fourth communication method in the embodiments of this application. For example... Figure 4 As shown, Figure 4 The methods shown may include S41, S42, S43 and S44.

[0123] S41, the terminal device determines the first time slot based on the index of the SSB.

[0124] S42, the network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information, which can be used to indicate the row index.

[0125] S43, in response to the PDCCH repetition condition being met, the terminal device determines the starting symbol value for N PDCCH listening opportunities in the first parameter configuration table according to the row index.

[0126] It should be noted that the "starting symbol value" in this article refers to the value in the parameter configuration table used to determine the starting symbol position in the time slot when the PDCCH listening time occurs.

[0127] S44, the terminal device determines the N PDCCH listening times associated with the SSB in the first time slot based on the N start symbol values ​​of the N PDCCH listening times.

[0128] In S41, the terminal device can first determine an SSB, and then determine the first time slot based on the index of that SSB. For details on determining the SSB, please refer to the relevant description of S11 above; it will not be repeated here.

[0129] Furthermore, the terminal device can determine the first time slot according to equation (2) above.

[0130] In S42, the network device indicates a row index to the terminal device. It should be noted that this embodiment does not limit the execution order of S41 and S42.

[0131] In practical implementation, the first indication information can be carried in the MIB. For example, the first indication information can be carried in the PDCCH configuration indication field (i.e., the pdcch-ConfigSIB1 field) in the MIB. The 4-bit value in the PDCCH configuration indication field is the row index indicated by the first indication information.

[0132] In S43, if the PDCCH repetition condition is met, the terminal device determines N start symbol values ​​based on the row index indicated by the first indication information and the first parameter configuration table. Furthermore, if the PDCCH repetition condition is not met, the terminal device determines a single start symbol value based on the row index indicated by the first indication information in the second parameter configuration table.

[0133] Specifically, both the first and second parameter configuration tables are parameter configuration tables. The parameter configuration tables in this document are used to configure the PDCCH listening timing. In the first parameter configuration table, each row contains N start symbol values. That is, each row index in the first parameter configuration table corresponds to N start symbol values. Based on a single row index, the terminal device can determine N start symbol values ​​in the first parameter configuration table. In the second parameter configuration table, each row contains a single start symbol value. That is, each row index in the first parameter configuration table corresponds to a single start symbol value. Based on a single row index, the terminal device can determine a single start symbol value in the second parameter configuration table.

[0134] Referring to Table 1, which shows a first parameter configuration table, each row in Table 1 contains two start symbol values. The first start symbol value (i.e., "start symbol value 1" in Table 1) corresponds to the start symbol value of the first PDCCH listening opportunity associated with the SSB, and the second start symbol value (i.e., "start symbol value 2" in Table 2) corresponds to the start symbol value of the second PDCCH listening opportunity associated with the SSB.

[0135] Table 1

[0136]

[0137] in, This indicates the number of symbols occupied by the PDCCH listening time. X represents the symbol offset value, which refers to the number of symbols between the end symbol position of the first PDCCH listening time and the start symbol position of the second PDCCH listening time.

[0138] Referring to Table 2, which shows one type of second parameter configuration table.

[0139] Table 2

[0140]

[0141] Where i represents the index of SSB.

[0142] In this embodiment, if the PDCCH repetition condition is met, the terminal device can determine N start symbol values ​​in the first parameter configuration table based on the row index indicated by the network. These N start symbol values ​​are used to determine the start symbol positions of the N PDCCH listening opportunities associated with the SSB. That is, the N start symbol values ​​corresponding to the row index in the first parameter configuration table are the start symbol values ​​of the N PDCCH listening opportunities, and these N start symbol values ​​correspond to the start symbol values ​​of the N PDCCH listening opportunities associated with the SSB. Each start symbol value can be used to determine the start symbol position of a single PDCCH listening opportunity within a time slot.

[0143] Referring to Table 1, for example, assuming the row index of the network indication is 2, the starting symbol values ​​for the two PDCCH listening opportunities can be: 0, Alternatively, the starting symbol values ​​for the two PDCCH listening times can be: 0, The starting symbol position of one of the two PDCCH listening opportunities is symbol 0 in the first time slot, and the starting symbol position of the other PDCCH listening opportunity is symbol 0 in the first time slot.

[0144] If the PDCCH repetition condition is not met, the terminal device can determine a single start symbol value in the second parameter configuration table based on the row index indicated by the network. That is, the single start symbol value corresponding to the row index in the second parameter configuration table is the start symbol value of the single PDCCH listening time associated with the SSB.

[0145] As one possible implementation, network devices can indicate the parameter configuration table applied in the current cell to terminal devices.

[0146] Specifically, the network device can send a second indication message to the terminal device, and the terminal device receives the second indication message. The second indication message can be used to indicate the parameter configuration table applied to the current cell. If the second indication message indicates that the parameter configuration table applied to the current cell is the first parameter configuration table, it means that the PDCCH repetition condition is met, and the terminal device determines N start symbol values ​​in the first parameter configuration table according to the row index indicated by the network. If the second indication message indicates that the parameter configuration table applied to the current cell is the second parameter configuration table, it means that the PDCCH repetition condition is not met, and the terminal device determines a single start symbol value in the second parameter configuration table according to the row index indicated by the network.

[0147] In other words, one possible implementation of "listening to PDCCH during the N PDCCH listening times associated with SSB in response to the PDCCH repetition condition being met" is as follows: if a second indication information is received, indicating that the parameter configuration table applied by the current cell is the first parameter configuration table, then the PDCCH is listened to during the N PDCCH listening times associated with SSB.

[0148] In specific implementations, the second indication information can be carried within the MIB. For example, the second indication information can be carried within the physical layer bit half-frame-index and physical layer bit within the MIB. and physical layer bits At least one of them.

[0149] In one example, a value of 1 for the physical layer bit half-frame-index in the MIB indicates that the current cell is using the first parameter configuration table. A value of 0 for the physical layer bit half-frame-index in the MIB indicates that the current cell is using the second parameter configuration table.

[0150] In another example, physical layer bits in the MIB A value of 1 indicates that the parameter configuration table used by the current cell is the first parameter configuration table. Physical layer bits in the MIB. A value of 0 indicates that the parameter configuration table used by the current cell is the second parameter configuration table.

[0151] In yet another example, the physical layer bits in the MIB A value of 1 indicates that the parameter configuration table used by the current cell is the first parameter configuration table. Physical layer bits in the MIB. A value of 0 indicates that the parameter configuration table used by the current cell is the second parameter configuration table.

[0152] As another possible implementation, if the current cell's frequency band belongs to the first frequency band, then the PDCCH repetition condition is met, or the parameter configuration table applied by the current cell is the first parameter configuration table. If the current cell's frequency band does not belong to the first frequency band, then the PDCCH repetition condition is not met, or the parameter configuration table applied by the current cell is the second parameter configuration table. The first frequency band can be defined by the protocol or configured by the network device. For example, the first frequency band can be a frequency band of non-terrestrial networks (NTNs).

[0153] In other words, one possible implementation of "listening to the PDCCH during the N PDCCH listening times associated with the SSB in response to the PDCCH repetition condition being met" is: if the frequency band of the current cell belongs to the first frequency band, then listen to the PDCCH during the N PDCCH listening times associated with the SSB.

[0154] It should be noted that more information on determining whether the PDCCH repetition condition is met can be found in the relevant description above, and will not be repeated here.

[0155] In S44, the terminal device can determine the starting symbol position of N PDCCH listening opportunities in the first time slot based on N starting symbol values, and further determine the N PDCCH listening opportunities associated with the SSB based on the number of symbols occupied by the PDCCH listening opportunities.

[0156] Therefore, in the scheme of Embodiment 4, a first parameter configuration table is introduced, in which a single row index corresponds to N start symbol values. If the PDCCH repetition condition is met, the terminal device determines the start symbol value of the N PDCCH listening opportunities associated with the SSB according to the row index indicated by the network, thereby determining the N PDCCH listening opportunities associated with the SSB.

[0157] For more details on Embodiment 4, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0158] Example 5

[0159] Reference Figure 5 , Figure 5 This is a flowchart illustrating the fifth communication method in the embodiments of this application. For example... Figure 5 As shown, Figure 5 The methods shown may include S51, S52, S53 and S54.

[0160] S51, the terminal device determines the first time slot based on the index of the SSB.

[0161] S52, the network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information, which can be used to indicate the row index.

[0162] S53, in response to the PDCCH repetition condition being met, the terminal device determines the starting symbol value of N PDCCH listening opportunities in N related parameter configuration tables based on the row index.

[0163] S54, the terminal device determines the N PDCCH listening times associated with the SSB in the first time slot based on the N start symbol values ​​of the N PDCCH listening times.

[0164] For details regarding S51 and S52, please refer to the relevant descriptions in Embodiment 4.

[0165] In this embodiment, the terminal device can be configured with N parameter configuration tables, where each row in each parameter configuration table contains a single start symbol value. That is, in each parameter configuration table, each row index corresponds to a single start symbol value.

[0166] In S53, if the PDCCH repetition condition is met, the terminal device can determine a single start symbol value from each of the N parameter configuration tables based on the row index, thus obtaining N start symbol values. That is, the start symbol values ​​for the N PDCCH listening opportunities are the start symbol values ​​corresponding to the row indexes indicated by the network in the N related parameter configuration tables.

[0167] In practice, the N parameter configuration tables may include the second parameter configuration table mentioned above. If the PDCCH repetition condition is not met, the terminal device can determine a single starting symbol value in the second parameter configuration table according to the row index indicated by the network.

[0168] As one possible implementation, the network device can send third indication information to the terminal device, and the terminal device receives the third indication information. This third indication information can be used to enable the association between N parameter configuration tables. If the association between the N parameter configuration tables is enabled, it indicates that the PDCCH repetition condition is met. If the association between the N parameter configuration tables is not enabled, it indicates that the PDCCH repetition condition is not met.

[0169] In practical implementation, the third indication information can be carried in the MIB. For example, the third indication information can be carried in the physical layer bit half-frame-index or physical layer bit within the MIB. and physical layer bits At least one of them.

[0170] In one example, a value of 1 for the physical layer bit half-frame-index in the MIB indicates that the association between the N parameter configuration tables is enabled. A value of 0 for the physical layer bit half-frame-index in the MIB indicates that the association between the N parameter configuration tables is disabled.

[0171] In another example, physical layer bits in the MIB A value of 1 indicates that the association between the N parameter configuration tables is enabled. Physical layer bits in the MIB. A value of 0 indicates that the association between the N parameter configuration tables is disabled.

[0172] In yet another example, the physical layer bits in the MIB A value of 1 indicates that the association between the N parameter configuration tables is enabled. Physical layer bits in the MIB. A value of 0 indicates that the association between the N parameter configuration tables is disabled.

[0173] Therefore, in S53, the terminal device can determine the starting symbol value for N PDCCH listening opportunities.

[0174] In S54, the terminal device can determine the starting symbol position of N PDCCH listening opportunities in the first time slot based on N starting symbol values, and further determine the N PDCCH listening opportunities associated with the SSB based on the number of symbols occupied by the PDCCH listening opportunities.

[0175] For example, N=2, and the N parameter configuration tables include: a second parameter configuration table and a third parameter configuration table.

[0176] Referring to Table 3, which shows a third parameter configuration table.

[0177]

[0178] In practical implementation, if the association between the second and third parameter configuration tables is enabled, the terminal device can determine a single start symbol value in the second parameter configuration table and a single start symbol value in the third parameter configuration table based on the row index indicated by the network, thereby obtaining two start symbol values, which are the start symbol values ​​for the two PDCCH listening opportunities. Furthermore, the terminal device can determine the start symbol positions of the two PDCCH listening opportunities in the first time slot based on the two start symbol values, thereby determining the two PDCCH listening opportunities associated with the SSB.

[0179] Therefore, in the scheme of Embodiment 5, N parameter configuration tables are set, and each row index in each parameter configuration table corresponds to a single start symbol value. In the case of repeated PDCCH transmission, the terminal device determines the single start symbol value in each of the N parameter configuration tables according to the row index indicated by the network device, thereby obtaining N start symbol values, which can determine the start symbol position of the N PDCCH listening opportunities.

[0180] For more details on Embodiment 5, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0181] Example 6

[0182] Reference Figure 6 , Figure 6 This is a flowchart illustrating the sixth communication method in the embodiments of this application. For example... Figure 6 As shown, Figure 6 The methods shown may include S61, S62, S63, S64 and S65.

[0183] S61, the terminal device determines the first time slot based on the index of the SSB.

[0184] S62, the network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information, which can be used to indicate the row index.

[0185] S63, the terminal device determines the starting symbol value of the reference PDCCH listening time among the N PDCCH listening times in the second parameter configuration table according to the row index.

[0186] S64, in response to the PDCCH repetition condition being met, the terminal device determines the starting symbol value of other PDCCH listening times among the N PDCCH listening times, excluding the reference PDCCH listening time, based on the starting symbol value and symbol interval of the reference PDCCH listening time.

[0187] S65, the terminal device determines the N PDCCH listening times associated with the SSB in the first time slot based on the N start symbol values ​​of the N PDCCH listening times.

[0188] For details regarding S61 and S62, please refer to the relevant descriptions in Embodiment 4.

[0189] In S63, the terminal device can determine a single start symbol value in the second parameter configuration table based on the row index indicated by the network. This start symbol value can be the start symbol value of a reference PDCCH listening time among N PDCCH listening times. For example, the reference PDCCH listening time can be the first PDCCH listening time. Alternatively, the reference PDCCH listening time can be the last PDCCH listening time.

[0190] In S64, if the PDCCH repetition condition is met, the starting symbol values ​​of the other PDCCH listening times among the N PDCCH listening times, excluding the reference PDCCH listening time, are determined based on the starting symbol value and symbol interval of the reference PDCCH listening time. If the PDCCH repetition condition is not met, a single PDCCH listening time is determined in the first time slot based on the single starting symbol value determined in the second parameter configuration table based on the row index of the network indication.

[0191] In this embodiment, the symbol interval can refer to the symbol interval between two adjacent PDCCH listening times out of N PDCCH listening times. In specific implementations, the symbol interval can be defined by the protocol or configured by the network device. For example, the value of the symbol interval can be any of the following: 0, 1, 2, 3, 4, 5, but is not limited to these.

[0192] In one possible implementation, the network device sends fourth indication information to the terminal device, and the terminal device receives the fourth indication information. The fourth indication information is used to indicate the symbol interval. In a specific implementation, the fourth indication information can be carried in the MIB. For example, the fourth indication information can be carried in the physical layer bit half-frame-index or physical layer bit within the MIB. and physical layer bits At least one of them.

[0193] Furthermore, the terminal device can determine (N-1) start symbol values ​​based on the start symbol value and symbol interval determined in S63. These start symbol values ​​are the start symbol values ​​of the (N-1) PDCCH listening opportunities other than the reference PDCCH listening opportunity. Thus, the terminal device can obtain the start symbol values ​​of the N PDCCH listening opportunities, and these start symbol values ​​are the start symbol values ​​of the N PDCCH listening opportunities associated with the SSB.

[0194] In S65, the terminal device can determine the starting symbol position of N PDCCH listening opportunities in the first time slot based on the starting symbol value of the N PDCCH listening opportunities. For example, if the PDCCH repetition condition is met, the terminal device can first determine a starting symbol value in the second parameter configuration table based on the row index indicated by the network. This starting symbol value is used to determine the starting symbol position of the first PDCCH listening opportunity among the N PDCCH listening opportunities. Further, based on the starting symbol position and symbol interval of the first PDCCH listening opportunity, the starting symbol position of the second PDCCH listening opportunity among the N PDCCH listening opportunities can be determined. Further, based on the starting symbol position and symbol interval of the second PDCCH listening opportunity, the starting symbol position of the third PDCCH listening opportunity among the N PDCCH listening opportunities can be determined, and so on, until the starting symbol position of each of the N PDCCH listening time slots is determined.

[0195] Based on the number of symbols occupied by the PDCCH listening time, the N PDCCH listening times associated with the SSB can be determined.

[0196] Therefore, in the scheme of Embodiment Six, a symbol interval is introduced between two adjacent PDCCH listening opportunities. If the PDCCH repetition condition is met, the terminal device determines a single starting symbol value in the second parameter configuration table according to the row index indicated by the network. Furthermore, based on the symbol interval, the starting symbol positions of N PDCCH listening opportunities can be determined, thereby determining the starting symbol positions of N PDCCH listening opportunities.

[0197] For more details on Embodiment Six, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0198] Example 7

[0199] Reference Figure 7 , Figure 7 This is a flowchart illustrating the seventh communication method in the embodiments of this application. Figure 7 The illustrated solution can be applied to terminal devices, for example, Figure 7The method shown can be executed by a terminal device, or by a chip or chip module with communication capabilities within the terminal device. For example... Figure 7 As shown, Figure 7 The method shown may include S71.

[0200] S71, in response to the PDCCH repetition condition being met, listen to the PDCCH at the N PDCCH listening times associated with the SSB, wherein the signal quality of the SSB is greater than or equal to a threshold, and N is a positive integer greater than 1.

[0201] In this context, "responding to the PDCCH repetition condition being met, listening to the PDCCH at the N PDCCH listening times associated with the SSB" means that if the PDCCH repetition condition is met, the PDCCH will be listened to at the N PDCCH listening times associated with the SSB.

[0202] Specifically, the terminal device can first determine the time slots where the N PDCCH listening opportunities are located based on the SSB index. For details regarding the time slots where the N PDCCH listening opportunities are located, please refer to the specific descriptions in Embodiments 1 to 3 above.

[0203] Furthermore, the terminal device can determine the starting symbol position of the N PDCCH listening opportunities based on the starting symbol values ​​of the N PDCCH listening opportunities, thereby determining the N PDCCH listening opportunities associated with the SSB. The specific details regarding the starting symbol values ​​of the N PDCCH listening opportunities can be found in the detailed descriptions of Embodiments 4 to 6 above.

[0204] Furthermore, network devices can repeatedly transmit the first downlink control information during N PDCCH listening sessions. Correspondingly, terminal devices can receive the first downlink control information during N PDCCH listening sessions and merge and decode the N identical downlink control information received to achieve PDCCH coverage enhancement.

[0205] It should be noted that the relationship between SSB and N PDCCH listening times in this article means that the time slot where the PDCCH listening time is located is determined based on the SSB index.

[0206] For more details about this embodiment, please refer to the above descriptions of Embodiments 1 to 6, which will not be repeated here.
