The embodiments of the present disclosure are mainly exemplarily described based on type 2 codebook, and the type 2 codebook is a dynamic codebook, and the codebook size will dynamically change with the actual data scheduling situation. Compared with the semi-static codebook mechanism of type 1 codebook, the type 2 codebook is beneficial to save the overhead of the codebook.

[0100] In some embodiments, the network device can send indication information to the terminal, for example, C_DAI (Cumulative Downlink Assignment Index), T_DAI (Total Downlink Assignment Index). Wherein, C_DAI and T_DAI can be carried by DCI (Downlink Control Information), and the DCI can be carried by PDCCH.

[0101] The C_DAI can indicate the cumulative number of PDSCHs or indicated SPS (Semi-Persistent Scheduling) releases scheduled by DCI (for example, DCI of format 1_0 or format 1_1) in the current cell up to the current PDCCH occasion.

[0102] The T_DAI can indicate the total number of PDSCHs scheduled by DCI in the current cell up to the current PDCCH occasion, for example, in the case of DCI scheduling PDSCH, it can also be understood as the total number of PDSCHs scheduled.

[0103] FIG. 1B is a schematic diagram of feedback according to an embodiment of the present disclosure.

[0104] As shown in FIG. 1B, for example, taking the case that a network device communicates with a terminal through three cells (Cell#1, Cell#2, and Cell#3) as an example, the horizontal axis in FIG. 1B is the time domain, and the vertical axis is the frequency domain.

[0105] Among them, the network device schedules three PDSCHs in Cell#1 in time sequence, schedules one PDSCH in Cell#2, and schedules three PDSCHs in Cell#3 in time sequence.

[0106] The network device can set the index of the time unit corresponding to the PDSCH, C_DAI, T_DAI, and the like based on the transmission time of the PDSCH, wherein the time unit includes but is not limited to a symbol, a slot, a radio frame, and the like, and the present disclosure does not limit this.

[0107] In the embodiment shown in FIG. 1B, the first PDSCH scheduled by the network device in Cell#1, the one PDSCH scheduled in Cell#2, and the first PDSCH scheduled in Cell#3 are transmitted at the same time, and the time unit index set for the three PDSCHs can be the same.

[0108] In the embodiment shown in FIG. 1B, the network device can also indicate (C_DAI, T_DAI). The network device schedules 1st PDSCH on Cell#1, 1 PDSCH on Cell#2, 1st PDSCH on Cell#3, and the 3 PDSCHs are scheduled at the same PDCCH occasion from the network device side, so the corresponding T_DAI is the same, which is 3. The C_DAI can be increased in turn, for example, the C_DAI corresponding to the 1st PDSCH on Cell#1 is 1, the C_DAI corresponding to the 1 PDSCH on Cell#2 is 2, and the C_DAI corresponding to the 1st PDSCH on Cell#1 is 3.

[0109] By analogy, the time unit indexes corresponding to the 2nd PDSCH on Cell#1 and the 2nd PDSCH on Cell#3 can be the same; the corresponding T_DAI is the same, which is 5; the C_DAI corresponding to the 2nd PDSCH on Cell#1 is 4, and the C_DAI corresponding to the 2nd PDSCH on Cell#3 is 5.

[0110] The time unit indexes corresponding to the 3rd PDSCH on Cell#1 and the 3rd PDSCH on Cell#3 can be the same; the corresponding T_DAI is the same, which is 7; the C_DAI corresponding to the 3rd PDSCH on Cell#1 is 6, and the C_DAI corresponding to the 3rd PDSCH on Cell#3 is 7.

[0111] As can be seen, the network device sends 7 PDSCHs to the terminal on 3 cells, so the codebook for feedback of the terminal can include 7 bits, which correspond to the 7 PDSCHs and respectively indicate the reception of the 7 PDSCHs.

[0112] For example, in the embodiment shown in FIG. 1B, the terminal fails to successfully detect the 3rd PDSCH on Cell#1 scheduled by the network device, so the 7 bits of feedback can be 1111101, wherein 1 indicates that the PDSCH is successfully detected, and 0 indicates that the PDSCH is not successfully detected.

[0113] It should be noted that the embodiment shown in FIG. 1B considers an ideal case, and the timing advance (TA) of the multiple cells used for communication between the network device and the terminal is the same, but in actual application, due to the difference in the deployment positions of different cells, the TA of different cells is different.

[0114] For example, in a non-terrestrial network (NTN), a network device communicates with a terminal through a satellite, and a cell corresponds to a satellite. Because different satellites are in different positions in the air, the distances from the network device and the terminal on the ground to the satellite are quite different, and thus the TA for different cells also varies greatly.

[0115] FIG. 1C is a schematic diagram of timing advance, according to an embodiment of the present disclosure.

[0116] Taking the communication between the network device and the terminal in the NTN as an example, it is considered that in the NTN, the network device communicates with the terminal through a satellite, and the satellite is located in the air. Information is sent from the ground, returned to the ground via the satellite, and the round-trip time (RTT) is relatively large, and thus the corresponding TA is also relatively large.

[0117] As shown in FIG. 1C, for example, the information sent by the network device to the terminal includes PDCCH in slot#n, which can carry DCI. The DCI can schedule PDSCH in slot#n. The slots after slot#n are slot#n+1, slot#n+2, slot#n+3, and the like.

[0118] For the terminal, due to the transmission delay, the terminal receives the PDCCH in slot#n at a relatively late time in the time domain, and a certain period of time is needed for processing, such as parsing, of the received PDCCH.

[0119] Because the RTT is large in the NTN network, when the terminal sends feedback (such as PUSCH) to the network device, the required TA is relatively large. For example, in FIG. 1C, the slot corresponding to the PUSCH sent based on the TA can be aligned with slot#n (for example, also slot#n), but the problem is that because the TA is large, the terminal may not actually send the PUSCH as feedback in slot#n or even several slots after slot#n.

[0120] For example, k2 can be introduced, which means the number of slots between the end of the PDCCH and the start of the PUSCH. In FIG. 1C, it can be understood as the number of slots between slot#n and the slot in which the PUSCH is sent.

[0121] Based on FIG. 1C, it can be known that the starting positions of the PUSCH corresponding to slot#n (k2=0), slot#n (k2=1), and slot#n (k2=2) are all before the end of the processing time of the terminal for the PDCCH, and thus cannot be actually used for transmitting the PUSCH. The starting position of slot#n+3 (k2=3) is after the end of the processing time of the terminal for the PDCCH, and thus can be actually used for transmitting the PUSCH. Therefore, the terminal can determine to transmit the PUSCH in slot#n+3 or a slot after slot#n+3.

[0122] FIG. 1D is a schematic diagram illustrating a feedback problem according to an embodiment of the present disclosure. FIG. 1E is a schematic diagram illustrating another feedback problem according to an embodiment of the present disclosure.

[0123] Taking an example of communication between a terminal and a network device through multiple cells in an NTN scenario, as shown in FIG. 1D and FIG. 1E, the terminal and the network device communicate through 3 cells (Cell#1, Cell#2, Cell#3) in the NTN scenario.

[0124] Among the 3 cells, Cell#1 corresponds to the maximum RTT, and thus the terminal receives information on Cell#1 last in the time domain. Cell#2 corresponds to the minimum RTT, and thus the terminal receives information on Cell#1 first in the time domain. Cell#2 corresponds to the median RTT, and thus the terminal receives information on Cell#1 second in the time domain.

[0125] It should be noted that the relationship among the 3 cells in the time domain shown in FIG. 1D and FIG. 1E is the time domain position at which the terminal receives information in each cell. For the network device, information on the 3 cells is transmitted simultaneously, and thus in FIG. 1D, the (C_DAI, T_DAI) indicated by the network device for the 3 cells is the same as that in FIG. 1B.

[0126] For FIG. 1E, the network device does not schedule a 3rd PDSCH on Cell#3, and thus the (C_DAI, T_DAI) set for the 3rd PDSCH scheduled on Cell#1 is (6, 6), which is different from (6, 7) in FIG. 1B, and the (C_DAI, T_DAI) corresponding to other PDSCHs is still the same as that in FIG. 1B.

[0127] As shown in FIG. 1D, because Cell#1 corresponds to the maximum RTT, the 3rd PDSCH on Cell#3 and the 2nd PDSCH on Cell#1 are received by the terminal in the same slot, which causes the terminal to have received the 3rd PDSCH on Cell#3 before determining whether the 3rd PDSCH scheduled by the network device is received on Cell#1.

[0128] Since the (C_DAI, T_DAI) corresponding to the third PDSCH on Cell#3 is (7, 7), the terminal determines that the PDSCH has been received in accordance with this, and then generates feedback information. However, in fact, the terminal has not attempted to receive the third PDSCH on Cell#1, which leads to the possibility of ambiguity in the sixth bit in the HARQ information generated by the terminal, and cannot accurately guarantee the reception of the third PDSCH on Cell#1.

[0129] As shown in FIG. 1E, the terminal receives the second PDSCH scheduled by the network device on Cell#1, and the (C_DAI, T_DAI) corresponding to the second PDSCH is (4, 5). However, since the maximum RTT corresponding to Cell#1, the terminal fails to receive PDSCH on Cell#2 and Cell#3 after receiving the second PDSCH on Cell#1, and thus mistakenly believes that the transmission of the PDSCH has ended, and thus may ignore the reception of the third PDSCH on Cell#1. This leads to the possibility that the HARQ information generated by the terminal may only contain 5 bits, instead of 6 bits, that is, the size of the feedback codebook is ambiguous.

[0130] Based on FIG. 1D and FIG. 1E, in the scenario where the network device communicates with the terminal through multiple cells, the codebook content or codebook size of the feedback may be ambiguous due to the excessively large RTT and other reasons.

[0131] FIG. 2 is an interaction diagram of an information sending method according to an embodiment of the present disclosure.

[0132] As shown in FIG. 2, the information sending method can include the following steps:

[0133] In step S201, the terminal receives information of multiple cells in a first time domain range.

[0134] In some embodiments, the network device sends information to the terminal through multiple cells.

[0135] In some embodiments, the first time domain range includes a starting time unit of information of the multiple cells that first reaches the terminal, to an ending time unit of information of the multiple cells that last reaches the terminal.

[0136] In some embodiments, the multiple cells are carrier aggregation cells. It should be noted that the multiple cells used by the terminal to communicate with the network device can be implemented based on carrier aggregation, or implemented based on other technologies, and the present disclosure does not limit this.

[0137] In some embodiments, the cell is a cell in a non-terrestrial network. It should be noted that the multiple cells used by the terminal to communicate with the network device can be cells in a non-terrestrial network or cells in a terrestrial network, and the present disclosure does not limit this. The following embodiments mainly take the cells in the non-terrestrial network as an example to exemplarily illustrate the technical solutions of the present disclosure.

[0138] In step S202, feedback of the information of the multiple cells is sent to the network device at the end time unit or the time unit after the end time unit.

[0139] In some embodiments, the information sent by the network device to the terminal in the multiple cells includes but is not limited to data, channels, data, for example, PDSCH, PDCCH, etc., and the present disclosure does not limit this.

[0140] In some embodiments, the feedback includes hybrid automatic repeat request (HARQ) information, such as HARQ-ACK, HARQ-NACK, and codebook bits in the HARQ information are used to indicate the reception of the information in the multiple cells. The codebook type can be type 1 codebook or type 2 codebook. The subsequent embodiments mainly take the type 2 codebook as an example to exemplarily illustrate the technical solutions of the present disclosure.

[0141] It should be noted that the present disclosure does not limit the determination method of the start time unit, the end time unit, and the time unit after the end time unit. The determination method of these time units will be exemplarily illustrated in the following embodiments, but the determination method of these time units is not limited to the cases described in the following embodiments.

[0142] According to the embodiments of the present disclosure, for the information sent by the network device in the multiple cells, the terminal can determine the start time unit of the information first arriving at the terminal in the information of the multiple cells, and the end time unit of the information last arriving at the terminal in the information of the multiple cells, and then generate feedback for the information of the multiple cells after completing the reception of the information corresponding to the multiple cells in the first time domain range between the start time unit and the end time unit, which is beneficial to ensure that the feedback can accurately indicate the reception of all the information on the multiple cells.

[0143] For example, for the case shown in FIG. 1D, according to the embodiments of the present disclosure, the terminal can determine that the third PDSCH on Cell#1 is the information last arriving at the terminal, instead of the third PDSCH on Cell#3. Accordingly, in the HARQ information generated by the terminal, the sixth bit can accurately indicate the reception of the third PDSCH on Cell#1.

[0144] For example, for the case shown in FIG. 1E, according to an embodiment of the present disclosure, the terminal can determine that the third PDSCH on Cell#1 is the last information arriving at the terminal, instead of the second PDSCH on Cell#3, and accordingly, the HARQ information generated by the terminal can include 6 bits instead of 5 bits, so as to accurately indicate the reception status of all PDSCHs on the three cells through 6 bits.

[0145] It should be noted that the terminal can not determine whether the reception of the PDSCH is completed according to the (C_DAI, T_DAI) corresponding to the PDSCH, but determine whether the reception of the PDSCH is completed according to other information (for example, the index of the time unit corresponding to the information, the TA corresponding to the cell, the compensation value K corresponding to the cell, etc.), so as to accurately determine which PDSCH is the last information arriving at the terminal. offset

[0146] In some embodiments, the reception time of the information of the plurality of cells is determined based on the index of the time unit in which the network device transmits the information on the plurality of cells.

[0147] For example, for the reception time of the information transmitted by the network device on the plurality of cells, the terminal can determine based on the index of the time unit in which the network device transmits the information on the plurality of cells. Since the index of the time unit in which the network device transmits the information on the plurality of cells is set by the network device, there can be a difference in the time at which the information on each cell arrives at the terminal (or referred to as the reception time of the terminal for the information on each cell), and thus it is beneficial to avoid the problem of receiving the information in the order of the reception time according to the time at which the information actually arrives at the terminal in the cells as shown in FIG. 1D and FIG. 1E.

[0148] For example, for the case shown in FIG. 1D, the terminal can first complete the reception of the information (for example, PDSCH) on the three cells at the downlink information (for example, PDCCH, PDSCH) reception time on slot#n, then complete the reception of the information on the three cells at the downlink information reception time on slot#n+1, and finally complete the reception of the information on the three cells at the downlink information reception time on slot#n+2. Accordingly, it can be ensured that the reception is determined to be completed only after the completion of the reception of the downlink information (the third PDSCH on Cell#3) on slot#n+2 on Cell#3. Accordingly, the reception of the third PDSCH on Cell#1 can be completed before the generation of the HARQ information, and thus the sixth bit in the generated HARQ information can accurately indicate the reception status of the third PDSCH on Cell#1.

[0149] In some embodiments, the association relationship between the bits in the HARQ information and the plurality of cells includes one of the following: ​

[0150] bits are associated with the plurality of cells in ascending order of cell indexes;

[0151] bits are associated with the plurality of cells in ascending order of the compensation values K offset corresponding to the plurality of cells.

[0152] For example, bits in the HARQ information are associated with the plurality of cells in ascending order of cell indexes. For example, for the embodiment shown in FIG. 1D, the 7 bits in the HARQ information can correspond to the 1st PDSCH on Cell#1, the 1st PDSCH on Cell#2, the 3rd PDSCH on Cell#1, the 2nd PDSCH on Cell#1, the 1st PDSCH on Cell#3, the 3rd PDSCH on Cell#1, and the 3rd PDSCH on Cell#3, respectively. In this case, the technical problem existing in FIG. 1D can be avoided in combination with any of the preceding embodiments.

[0153] For example, bits in the HARQ information are associated with the plurality of cells in ascending order of the compensation values K offset corresponding to the plurality of cells. In this case, the K offset corresponding to each cell can be determined. offset For example, taking FIG. 1D as an example, where the K offset corresponding to Cell#2 is the smallest, the K offset corresponding to Cell#3 is in the middle, and the K offset,min corresponding to Cell#1 is the largest, then the 7 bits in the HARQ information can correspond to the 1st PDSCH on Cell#2, the 1st PDSCH on Cell#3, the 2nd PDSCH on Cell#3, the 3rd PDSCH on Cell#3, the 1st PDSCH on Cell#1, the 2nd PDSCH on Cell#1, and the 3rd PDSCH on Cell#1, respectively. In this case, the technical problem existing in FIG. 1D can be avoided in combination with any of the preceding embodiments.

[0154] The starting time unit, the ending time unit, and the time unit after the ending time unit are exemplarily described in the disclosure through several embodiments.

[0155] In some embodiments, the identity of the starting time unit is determined according to the following formula:

[0156] The identity of the ending time unit is determined according to the following formula:

[0157] wherein n1 is the index of the time unit in which the network device transmits information in the plurality of cells, K offset,min is the smallest K offset in the compensation values K offset corresponding to the plurality of cells.offset,max Kmin is the minimum of K offset Kmin is the minimum of K offset μ is the SCS configuration for the uplink transmission, is a predefined value.

[0158] In some embodiments, each cell can correspond to a compensation value K offset The meaning of the compensation value K offset may refer to the related art, and the present disclosure does not limit this. The compensation value K offset may be determined based on the ephemeris information of the satellite corresponding to the cell, or can be configured by the network device, or can be predefined, and the present disclosure does not limit the determination manner of the compensation value K offset .

[0159] In some embodiments, n1 is the index of the time unit in which the network device transmits information in the plurality of cells, for example, the index of the time unit in which any information transmitted by the network device in the plurality of cells is located, for example, in the scenarios shown in FIG. 1D and FIG. 1E, n1 can be the index of the time unit (slot#n) in which the network device transmits the first information in the plurality of cells. For example, the sum of n1 and K offset may be used as the index of the time unit in which the terminal actually receives the information in slot#n.

[0160] For example, taking n1=100 as an example, K offset corresponding to each cell can be determined, and K offset and K offset,min are determined from these K offset,max , for example, K offset,min =2 and K offset,max =4.

[0161] μ is the SCS configuration for the uplink transmission (for example, PUCCH, PUSCH). For example, μ=0 in the absence of SCS.

[0162] is a predefined value, for example, under FR1 frequency points, and under FR2 frequency points in the NTN scenario, may be equal to 0.

[0163] For convenience of description, taking μ and both as 0 as an example, then In this case, That is, when the network device starts to send information on multiple cells from slot#n, the terminal expects to receive the information sent by the network device on multiple cells in the time range of slot#102 to slot#104.

[0164] In some embodiments, the identity of the time unit where the feedback is located is determined according to the following formula:

[0165] where n2 is the index of the ending time unit, or the index of the first time unit after the ending time unit, koffset,PUCCH is the compensation value K corresponding to the cell used for sending the feedback offset , k1 is the number of interval time units between the ending time unit and the time unit where the feedback is located, koffset,last is the K corresponding to the cell whose information arrives at the terminal last among the information of multiple cells offset , μ is the subcarrier spacing configuration used for uplink transmission, is a predefined value.

[0166] In some embodiments, the terminal can send the feedback to the network device at the ending time unit, or send the feedback to the network device at a time unit after the ending time unit. Since it takes a period of time for the terminal to process the information, a parameter related to the processing capability of the terminal, for example, k1, can be introduced to represent the number of interval time units between the ending time unit and the time unit where the feedback is located.

[0167] It should be noted that the foregoing embodiments mainly describe the case where the starting time units of the network device for sending information on multiple cells are the same, for example, slot#n are all slot#100, but the disclosure is not limited to the case where the starting time units of the network device for sending information on multiple cells are the same.

[0168] For example, for the three cells of Cell#1, Cell#2 and Cell#3, the starting time units of the network device for sending information on the three cells are slot#100, slot#102 and slot#104 respectively, and the compensation values K offset corresponding to the three cells can be different, for example, K offset corresponding to Cell#1 is 2, K offset corresponding to Cell#2 is 3, and K offset corresponding to Cell#3 is 4, then the ending time unit of the terminal for receiving information on the three cells is slot#104+4, that is, slot#108, and koffset,last is K offset corresponding to Cell#3, that is, koffset,last=4.

[0169] In the case that n2 is the index of the first time unit after the ending time unit, n2 = 108 + 1 = 109, on the basis of which, for example, k1 = 2, koffset,PUCCH = 2, μ and all are 0, then:

[0170] Accordingly, the terminal can send the feedback in slot#116.

[0171] In the case that n2 is the index of the ending time unit, n2 = 108, on the basis of which, for example, k1 = 2, koffset,PUCCH = 2, μ and all are 0, then:

[0172] Accordingly, the terminal can send the feedback in slot#115.

[0173] It should be noted that the above several embodiments indicate for exemplary description on the determination manner of the starting time unit, the ending time unit, and the time unit after the ending time unit, and the determination manner of these time units is not limited to the cases described in the subsequent embodiments.

[0174] In some embodiments, the terminal does not expect to receive the updated information of the compensation value K offset corresponding to any of the plurality of cells in the process of receiving the information of the plurality of cells, and / or in the process of sending the feedback to the network device.

[0175] According to the foregoing embodiments, it can be known that the embodiments of the present disclosure can mainly determine the information about the starting time unit, the ending time unit, and the time unit where the feedback is located according to the compensation value K offset corresponding to the cell, and if the network device adjusts K offset in the process of receiving the information of the plurality of cells by the terminal, and / or in the process of sending the feedback to the network device, it will cause the process of determining the information about the starting time unit, the ending time unit, and the time unit where the feedback is located by the terminal to have a problem. Therefore, in the present embodiment, the network device will not update K offset in the process of receiving the information of the plurality of cells by the terminal, and / or in the process of sending the feedback to the network device, and the terminal also does not expect to receive the updated information of K offset in the process of receiving the information of the plurality of cells by the terminal, and / or in the process of sending the feedback to the network device, so as to avoid the above problem.

[0176] The communication method related to the embodiments of the present disclosure can include at least one of steps S201-S202. For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, steps S201+S202 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.
