[0039] According to one embodiment of the present invention, an embodiment of a method for processing a channel is provided. The steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. Although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here. The method for processing a channel of a terminal device of an embodiment of the present invention is introduced from the terminal side. Figure 1 FIG. 1 is a flow chart of a channel processing method according to one embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:
[0040] Step S102, the terminal receives downlink control signaling DCI and determines the timing parameters in the DCI. The terminal may receive downlink control signaling (Downlink Control Information, referred to as DCI) sent by a network device, and the DCI carries the timing parameters of the channel, that is, the DCI indicates the timing parameters, which are also called timing indication information. After receiving the DCI, the terminal determines the above timing parameters from the DCI.
[0041] Step S104, the terminal determines the time interval between the first channel and the second channel according to the timing parameters, wherein the first channel and the second channel respectively correspond to at least one transmission time unit. The time interval may be the timing offset between the transmission time unit in the first channel and the transmission time unit in the second channel, which determines the timing relationship between the first channel and the second channel. The transmission time unit is also called a transmission time slot, and the first channel corresponds to at least one transmission time unit, that is, the first channel is configured with a channel repetition transmission mechanism, and the second channel corresponds to at least one transmission time unit, that is, the second channel is also configured with a channel repetition transmission mechanism.
[0042] Optionally, the first channel and the second channel of this embodiment are respectively: a physical downlink shared channel (Physical Downlink Shared Channel, abbreviated as PDSCH) and a physical downlink control channel (Physical Downlink Control Channel, abbreviated as PDCCH); or, a physical uplink shared channel (Physical Uplink Shared Channel, abbreviated as PUSCH) and PDCCH; or, a physical uplink control channel (Physical Uplink Control Channel, abbreviated as PUCCH) and PDSCH.
[0043] Step S106: The terminal determines a transmission time unit of the first channel according to the time interval, wherein the transmission time unit of the first channel is the first transmission time unit of at least one transmission time unit corresponding to the first channel, and the determined transmission time unit of the first channel is also called the timing of the first channel, for example, the sending timing of the first channel.
[0044] Optionally, after the terminal determines the transmission time unit of the first channel, the terminal determines the reception time of the first channel based on the transmission time unit of the first channel, and then receives the first channel according to the reception time, for example, the first channel is PDSCH; Optionally, the terminal can also determine the transmission time of the first channel based on the transmission time unit of the first channel, and then transmit the first channel according to the transmission time, for example, the first channel is PUSCH or PUCCH. Optionally, in the NR system, since the time interval between the first channel and the second channel is determined by the timing parameter, and the timing parameter is indicated by the DCI, the time interval is dynamically variable.
[0045] In the above steps S102 to S106 of the present application, the channel retransmission mechanism is adopted to determine the timing parameters indicated in the DCI, so that the terminal can correctly determine the transmission time unit of the corresponding channel in the scenario of channel repeated transmission, adapt to terminals with low bandwidth capabilities, and solve the technical problem that the transmission time unit of the channel cannot be accurately determined in the scenario of channel repeated transmission, thereby achieving the technical effect of accurately determining the transmission time unit of the channel in the scenario of channel repeated transmission.
[0046] The above method of this embodiment is further introduced below.
[0047] As an optional implementation, step S104, the terminal determines the time interval between the first channel and the second channel according to the timing parameter, including: the terminal determines the time interval between at least one first transmission time unit in at least one transmission time unit corresponding to the first channel and at least one second transmission time unit in at least one transmission time unit corresponding to the second channel according to the timing parameter. Among them, at least one first transmission time unit in at least one transmission time unit corresponding to the first channel can be any transmission time unit in at least one transmission time unit corresponding to the first channel, for example, the first transmission time unit in at least one transmission time unit corresponding to the first channel. Optionally, the at least one first transmission time unit as a complete set of this embodiment is related to the transmission information of the first channel; at least one second transmission time unit in at least one transmission time unit corresponding to the second channel can be any transmission time unit in at least one transmission time unit corresponding to the second channel, for example, the last transmission time unit in at least one transmission time unit corresponding to the second channel. Optionally, the terminal determines the time interval between the at least one first transmission time unit and at least one second transmission time unit in at least one transmission time unit according to the timing parameter.
[0048] As an optional implementation, the method further includes: the terminal determines at least one transmission time unit corresponding to the second channel according to the transmission information of the second channel. In this embodiment, the transmission information of the second channel is determined, and the transmission information is also the channel retransmission information. The at least one transmission time unit corresponding to the second channel corresponds to the transmission information of the second channel, and the terminal can determine at least one transmission time unit corresponding to the second channel according to the transmission information of the second channel.
[0049] As an optional implementation, step S106, the terminal determines the transmission time unit of the first channel according to the time interval, including: the terminal determines the transmission time unit of the first channel according to the time interval and the transmission information of the second channel. In this embodiment, the terminal can determine the transmission time unit of the first channel according to the timing parameter and the transmission information of the second channel, for example, the transmission time unit of the first channel is the first transmission time unit of at least one transmission time unit corresponding to the first channel. Since the time interval between the first channel and the second channel can be determined by the timing parameter, the transmission time unit of the first channel is further determined according to the time interval and the transmission information of the second channel, that is, the sending timing of the first channel is determined.
[0050] As an optional implementation, the transmission information of the second channel includes: a first number of at least one transmission time unit corresponding to the second channel and a first transmission time unit of at least one transmission time unit corresponding to the second channel, and the terminal determines the transmission time unit of the first channel according to the time interval and the transmission information of the second channel, including: the terminal determines at least one second transmission time unit according to the first number and the first transmission time unit of at least one transmission time unit corresponding to the second channel; the terminal determines at least one transmission time unit of at least one first transmission time unit according to the time interval and at least one transmission time unit of at least one second transmission time unit; the terminal determines at least one transmission time unit of at least one first transmission time unit as the transmission time unit of the first channel.
[0051] In this embodiment, the transmission information of the second channel may include the first number of at least one transmission time unit corresponding to the second channel, that is, the number of repeated transmissions of the second channel. The transmission information of the second channel may also include the first transmission time unit of at least one transmission time unit corresponding to the second channel, that is, the starting time slot of repeated transmission of the second channel. The terminal of this embodiment determines at least one second transmission time unit of at least one transmission time unit corresponding to the second channel according to the first number and the first transmission time unit of at least one transmission time unit corresponding to the second channel. For example, the at least one second transmission time unit is the last transmission time unit of at least one transmission time unit corresponding to the second channel. The terminal may determine at least one transmission time unit of at least one first transmission time unit according to the time interval and at least one transmission time unit of at least one second transmission time unit, wherein at least one second transmission time unit and at least one first transmission time unit may be understood as the concept of a complete set. Optionally, at least one transmission time unit of at least one second transmission time unit is the last transmission time unit of at least one transmission time unit corresponding to the second channel, and at least one transmission time unit of at least one first transmission time unit may be the first transmission time unit of at least one transmission time unit corresponding to the first channel. The terminal determines at least one transmission time unit of at least one first transmission unit as the transmission time unit of the first channel of this embodiment.
[0052] As an optional implementation, the terminal determines at least one transmission time unit among at least one first transmission time unit based on the time interval and at least one transmission time unit among at least one second transmission time unit, including: the terminal determines whether the transmission time unit obtained through the time interval and at least one transmission time unit among at least one second transmission time unit belongs to a time unit set; if the obtained transmission time unit belongs to the time unit set, the terminal determines the obtained transmission time unit as at least one transmission time unit among at least one first transmission time unit; if the obtained transmission time unit does not belong to the time unit set, the terminal determines the transmission time unit belonging to the time unit set after the obtained transmission time unit as at least one transmission time unit among at least one first transmission time unit.
[0053] In this embodiment, the terminal can calculate the transmission time unit through the time interval and at least one transmission time unit in at least one second transmission time unit. For example, the terminal calculates the transmission time unit through the time interval and the last transmission time unit in at least one transmission time unit corresponding to the second channel. The calculated transmission time unit cannot be determined as at least one transmission time unit in the final at least one first transmission time unit, and it is also necessary to determine whether the calculated transmission time unit belongs to the time unit set, which is also the time slot set. If it is determined that the calculated transmission time unit belongs to the above-mentioned time unit set, the terminal can directly determine the calculated transmission time unit as at least one transmission time unit in at least one first transmission time unit. Optionally, if it is determined that the calculated transmission time unit does not belong to the time unit set, the terminal needs to determine the transmission time unit belonging to the time unit set after the calculated transmission time unit as at least one transmission time unit in at least one first transmission time unit, for example, the first transmission time unit belonging to the transmission time unit set after the calculated transmission time unit is determined as the first transmission time unit in at least one transmission time unit corresponding to the first channel.
[0054] As an optional implementation, when the first channel is the physical downlink shared channel PDSCH and the second channel is the PDCCH, the time unit set is the first time unit set, and the first time unit set is the available downlink time unit set. In this embodiment, the first time unit set is also called the first time slot set, which can be a downlink time slot set available for the NR-light system, and the time slot set can be obtained through high-level configuration information, for example, through radio resource control (Radio Resource Control, referred to as RRC) signaling, system messages, broadcast messages, etc. In a time division duplex (TDD) system, the first time unit set may also be related to the configuration of uplink and downlink time slots. Optionally, PDCCH belongs to the first time unit set.
[0055] As an optional implementation, when the first channel is a physical uplink shared channel PUSCH and the second channel is PDCCH, or when the first channel is a physical uplink control channel PUCCH and the second channel is PDSCH, the time unit set is a second time unit set, and the second time unit set is an available uplink time unit set. In this embodiment, the second time unit set is also called a second time slot set, which can be an uplink time slot set available for the NR-light system, and can be obtained through high-level configuration information, for example, through RRC signaling, system messages, broadcast messages, etc. Optionally, PDCCH belongs to the first time unit set. Optionally, PDSCH belongs to the first time unit set.
[0056] In this embodiment, the transmission information of the second channel includes the first transmission time unit in at least one transmission time unit corresponding to the second channel. The method for determining the first transmission time unit in the at least one transmission time unit is introduced below. As an optional implementation, the terminal obtains the first transmission time unit in at least one transmission time unit corresponding to the PDCCH through high-level signaling and / or DCI when the first channel is PDSCH and the second channel is PDCCH, or when the first channel is PUSCH and the second channel is PDCCH. In this embodiment, the first channel may be PDSCH and the second channel may be PDCCH, or the first channel may be PUSCH and the second channel may be PDCCH. In the above two cases, the second channel is PDCCH. Then, the transmission information of the second channel includes the first transmission time unit in at least one transmission time unit corresponding to the PDCCH, which can be determined by at least one of high-level signaling and DCI, so as to achieve the purpose of determining the starting time slot for repeated transmission of the PDCCH.
[0057] As an optional implementation, the method further includes: when the first channel is PUCCH and the second channel is PDSCH, the terminal determines the first transmission time unit of at least one transmission time unit corresponding to the PDSCH according to the time interval between the last transmission time unit of at least one transmission time unit corresponding to the PDCCH and the first transmission time unit of at least one transmission time unit corresponding to the PDSCH and the transmission information of the PDCCH. Wherein, the transmission information of the PDCCH includes the first number of at least one transmission time unit corresponding to the PDCCH and the first transmission time unit of at least one transmission time unit corresponding to the PDCCH, and the last transmission time unit of at least one transmission time unit corresponding to the PDCCH can be determined according to the first number of at least one transmission time unit corresponding to the PDCCH and the first transmission time unit of at least one transmission time unit corresponding to the PDCCH, and then the first transmission time unit of at least one transmission time unit corresponding to the PDSCH can be obtained through the time interval between the last transmission time unit of at least one transmission time unit corresponding to the PDCCH and the first transmission time unit of at least one transmission time unit corresponding to the PDSCH and the above-mentioned first transmission time unit of at least one transmission time unit corresponding to the PDSCH.
[0058] As an optional implementation, the method further includes: the terminal obtains the first quantity through high-level signaling and / or DCI. In this embodiment, the transmission information of the second channel may include a first quantity of at least one transmission time unit corresponding to the second channel, and the first quantity can be determined through at least one of high-level signaling and DCI regardless of whether the first channel and the second channel are PDSCH and PDCCH, or PUSCH and PDCCH, or PUCCH and PDSCH, respectively.
[0059] As an optional implementation, the DCI carried by the PDCCH includes a timing parameter, and there is a second number of transmission time units between at least one transmission time unit in at least one first transmission time unit and at least one transmission time unit in at least one second transmission unit, wherein the timing parameters included in the DCI carried by the PDCCH in at least two transmission time units are the same, and the timing parameters are the second number; or, the timing parameters included in the DCI carried by the PDCCH in at least two transmission time units are different, and the second number is determined according to at least one timing parameter among the different timing parameters. Among them, there is a second number of transmission time units between at least one transmission time unit in at least one first transmission time unit and at least one transmission time unit in at least one second transmission unit, which may be that the number of transmission time units between the first transmission time unit in at least one transmission time unit corresponding to the first channel and the last transmission time unit in at least one transmission time unit corresponding to the second channel is the second number. The above-mentioned PDCCH of this embodiment may have the same timing parameters included in the DCI carried by at least two transmission time units, or may have the same timing parameters included in the DCI carried by each transmission time unit, and the timing parameters may be the above-mentioned second number; optionally, the timing parameters included in the DCI carried by the PDCCH in at least two transmission time units are different, in which case the above-mentioned second number may be determined based on at least one of the different timing parameters.
[0060] As an optional implementation manner, step S104, the terminal determines the time interval between the first channel and the second channel according to the timing parameter, including: the terminal determines the time interval corresponding to the second number as the time interval. In this embodiment, the timing parameter may be the second number, and the terminal determines the time interval between the first channel and the second channel according to the second number, which may be to determine the time interval corresponding to the second number.
[0061] As an optional implementation, the second number is the minimum number of transmission time units between at least one transmission time unit in at least one first transmission time unit and at least one transmission time unit in at least one second transmission unit. The second number contained in the DCI carried by the PDCCH may be the minimum number of transmission time units between the first transmission time unit in at least one transmission time unit corresponding to the first channel and the last transmission time unit in at least one transmission time unit corresponding to the second channel, that is, the minimum number of time slots. When the first channel is PDSCH and the second channel is PDCCH, the actual second number is related to the timing parameters and the first time unit set; when the first channel is PUSCH and the second channel is PDCCH, or when the first channel is PUCCH and the second channel is PDSCH, the actual second number is related to the timing parameters and the second time unit set.
[0062] In the above method, at least one first transmission time unit may be the first transmission time unit of at least one transmission time unit corresponding to the first channel, and at least one second transmission unit may be the last transmission unit of at least one transmission time unit corresponding to the second channel; the method of this embodiment is further illustrated below with the first channel and the second channel being: PDSCH and PDCCH; or, PUSCH and PDCCH; or, PUCCH and PDSCH.
[0063] As an optional example, the first channel and the second channel are PDSCH and PDCCH respectively, and the transmission time unit of PDSCH is determined according to the transmission information and timing parameters of PDCCH. The interval between the last subframe of the existing machine-to-machine communication (MTC) transmission and the first subframe of PDSCH is predefined. In the NR system, since the time interval between the time slot of PDCCH transmission and the time slot of PDSCH transmission is indicated by DCI, it is dynamically variable.
[0064] This embodiment determines the first transmission time unit of PDSCH transmission according to the first transmission time unit of repeated transmission of PDCCH, the number of repeated transmissions, and the timing parameter K0 contained in the DCI carried by PDCCH. The timing parameter K0 is the number of transmission time units between the last transmission time unit of repeated transmission of PDCCH and the first transmission time unit of repeated transmission of PDSCH. Figure 2 FIG. 1 is a schematic diagram of determining the first transmission time unit among multiple transmission time units corresponding to a PDSCH according to one embodiment of the present invention. Figure 2As shown, the timing parameter K0=4, when the transmission time unit determined according to the first transmission time unit of repeated transmission of PDCCH, the number of repeated transmissions, and the timing parameter K0 contained in the DCI carried by PDCCH is time slot 8, but time slot 8 does not belong to the first time unit set, then the first transmission time unit set of PDSCH transmission is determined to be the next time slot belonging to the first time unit set after time slot 8, that is, time slot 9. Optionally, the timing parameter K0 contained in the DCI carried by PDCCH is the minimum number between the last transmission time unit of PDCCH transmission and the first transmission time unit of PDSCH transmission. The actual number of transmission time units is related to the timing parameter K0 and the first time unit set.
[0065] As another optional example, the first channel and the second channel are PUSCH and PDCCH respectively, and the timing of the PUSCH channel is determined according to the transmission information and timing parameters of the PDCCH. In the existing MTC system, when the MPDCCH is configured with repeated transmission, the interval between the first subframe of the PUSCH transmission scheduled by the MPDCCH and the last subframe of the MPDCCH transmission is 4 in the frequency division duplex (FDD) system, and is determined according to the uplink and downlink configuration in the TDD system. Among them, the interval between the last subframe of the MPDCCH transmission and the first subframe of the PDSCH is predefined. In the NR system, since the time interval between the time slot of the PDCCH transmission and the time slot of the PUSCH transmission is indicated by the DCI, it is dynamically variable.
[0066] In this embodiment, the transmission time unit of the PDCCH belongs to the first time unit set, and the transmission time unit set of the PUSCH belongs to the second time unit set. The first transmission time unit of the PDSCH transmission is determined according to the first transmission time unit of the repeated transmission of the PDCCH and the number of repeated transmissions, and the timing parameter K2 included in the DCI carried by the PDCCH. The included timing parameter K2 is the number of transmission time units between the last transmission time unit of the PDCCH transmission and the first transmission time unit of the PUSCH transmission, wherein the last transmission time unit of the PDCCH can be determined according to the first transmission time unit of the repeated transmission of the PDCCH and the number of repeated transmissions. Figure 3 FIG. 1 is a schematic diagram of determining the first transmission time unit among multiple transmission time units corresponding to a PUSCH according to one embodiment of the present invention. Figure 3As shown, the timing parameter K2=4, and the first transmission time unit of PUSCH transmission is determined to be time slot 8, but time slot 8 does not belong to the second time unit set, then the first transmission time unit of PUSCH transmission is determined to be the next time slot of time slot 8 that belongs to the second time unit set, that is, time slot 9. Optionally, the timing parameter K2 included in the DCI carried by the PDCCH is the minimum number of transmission time units between the last transmission time unit of the PDCCH transmission and the first transmission time unit of the PUSCH transmission. The actual number of transmission time unit sets is related to the timing parameter K2 and the second time unit set.
[0067] As another optional example, the first channel and the second channel are PUCCH and PDSCH respectively, and the transmission time unit of PUCCH is determined according to the transmission information and timing parameters of PDSCH. In the existing MTC system, in FDD mode, when MPDCCH is configured for repeated transmission, the PDSCH transmission scheduled by MPDCCH starts at the second BL / CE downlink subframe after the last subframe of MPDCCH transmission. And, if PDSCH is transmitted in subframe n, its corresponding HARQ-ACK information is carried on the PUCCH sent in subframe n+4. In the NR system, since the time interval between the transmission time unit of PDSCH and the time slot of PUCCH transmission carrying the HARQ-ACK information corresponding to the PDSCH is indicated by DCI, it is dynamically variable.
[0068] This implementation can determine the first transmission time unit of PUCCH transmission based on the first repeated transmission time unit and the number of repetitions of the repeated transmission of PDSCH, and the K1 information contained in the DCI carried by PDSCH; optionally, the timing parameter K1 contained in the DCI is the number of transmission time units between the last transmission time unit of PDSCH transmission and the first transmission time unit of PUCCH transmission, and the last transmission time unit of PDSCH transmission can be determined based on the first repeated transmission time unit and the number of repeated transmissions of PDSCH repeated transmission, and the first transmission time unit of PDSCH repeated transmission can be determined based on the first transmission time unit and the number of repeated transmissions of PDCCH repeated transmission, and the timing parameter K0 contained in the DCI carried by PDCCH.
[0069] Optionally, the transmission time unit of the above-mentioned PUCCH belongs to the above-mentioned second time unit set. Figure 4 FIG. 1 is a schematic diagram of determining the first transmission time unit among multiple transmission time units corresponding to a PUCCH according to one embodiment of the present invention. Figure 4As shown, the timing parameter K1=6, the transmission time unit of the PUCCH determined according to the starting time slot and the number of repetitions of the repeated transmission of the PDSCH, and the timing parameter K1 contained in the DCI carried by the PDSCH is time slot 3, but time slot 3 does not belong to the third time slot set, then the first transmission time unit of the PUCCH transmission is determined to be the next time slot belonging to the second time unit set after time slot 3, that is, time slot 4. Optionally, the timing parameter K1 contained in the DCI carried by the PDCCH is the minimum number of transmission time units between the last transmission time unit of the PDSCH transmission and the first transmission time unit of the PUCCH transmission. The actual number of transmission time units is related to the timing parameter K1 and the second time unit set.
[0070] In the related art, when implementing PDSCH transmission in NR, the base station carries a time domain resource allocation (TDRA) field in the DCI of the downlink grant (DL grant), which can indicate the starting position S, length L, k0 and different types of PDSCH. k0 represents the number of offset slots between the time slot where the DCI is located and the slot where the PDSCH is located. Table 1 is a DL grant indicating ACK / NACK feedback information transmission resource table. Among them, the PDSCH-to-HARQ_feedback timing indicator indicates the number of slots between the PDSCH and the PUCCH. The PUCCH resource indicator indicates a row in the predefined resource list, including the time domain resources, frequency domain resources and spread spectrum sequence resources of the PUCCH in a slot.

[0073] Figure 5 FIG. 1 is a schematic diagram of a PDCCH scheduling PDSCH according to a related technology. Figure 5 As shown, PDCCH schedules PDSCH, when K0 is 0, 1, 2, and K1 is 5, 4, 2, PDSCH can be scheduled by PDCCH.
[0074] In the related art, when implementing PUSCH transmission in NR, the base station sends an uplink grant (UL grant) to schedule PUSCH transmission. When the base station schedules uplink data transmission through the DCI of the UL grant, it will carry a TDRA field in the DCI. The TDRA field is 4 bits and can indicate 16 different rows in a resource allocation table, such as the starting position S, length L, k2, and different types of PDSCH. Among them, k2 represents the number of offset slots between the slot where the DCI is located and the slot where the PUSCH is located. Figure 6 FIG. 1 is a schematic diagram of a PDCCH scheduling PUSCH according to a related technology. Figure 6 As shown, when K2 is 0, 1, or 2, PUSCH can be scheduled through PDCCH.
[0075] In the related art, for the MPDCCH in the MTC system, the MPDCCH is introduced in the LTE MTC system. The transmission of the MPDCCH introduces frequency hopping and repetition. The resources occupied by the MPDCCH are frequency-division multiplexed with the physical downlink shared channel PDSCH. Figure 7 As shown, Figure 7 The present invention is a schematic diagram of PDCCH scheduling PDSCH according to a related art. For the PDSCH scheduled by MPDCCH, the MPDCCH is in a narrowband frequency-divided with the PDSCH. The MPDCCH supports repetition in multiple subframes, and the MPDCCHs in different subframes can be frequency-hopped. The MPDCCH and the PDSCH scheduled by it may not be in the same narrowband, and the DCI carried in the MPDCCH may indicate the narrowband where the PDSCH is located. Figure 8 FIG. 1 is a schematic diagram of an MPDCCH supporting repetition in multiple subframes according to one embodiment of the present invention. Figure 8 As shown, the downlink physical channel MPDCCH of different subframes can hop. MPDCCH and its scheduled PDSCH may not be in the same frequency domain subband. In the MTC system, both MPDCCH and its scheduled PDSCH can be repeatedly transmitted. The repeated transmission of MPDCCH is repeated in downlink subframes, and the PDSCH of N BL / CE downlink subframes is continuously sent starting from the second BL / CE (Bandwidth reduced Low complexity / Coverage Enhancement, which is a UE type introduced in the MTC system) downlink subframe after the last subframe of MPDCCH transmission.
[0076] Fig. 9 FIG. 1 is a schematic diagram of PDSCH transmission in an MTC system according to the related art. Fig. 9As shown in FIG. 1 , the number of repetitions of the MPDDCH is 4, the number of repetitions of the PDSCH is 16, and the PDSCH starts at the second BL / CE downlink subframe after the last subframe transmitted by the MPDCCH.
[0077] In the above-mentioned related technologies, if channel repetition transmission is introduced in the NR-light system, it is necessary to reconsider the timing relationship between the PDCCH, PDSCH, and PUSCH channels, but the timing relationship defined by the existing NR system is not applicable to the scenario of channel repetition transmission. In this embodiment, the terminal receives the downlink control signaling DCI and determines the timing parameters in the DCI, and the present application adopts the channel retransmission mechanism to determine the meaning of the timing parameters indicated in the DCI, such as the time interval between the last transmission time unit of the PDCCH transmission and the first transmission time unit of the PDSCH / PUSCH transmission, or the time interval between the last transmission time unit of the PDSCH transmission and the first transmission time unit of the PUCCH transmission, so that the terminal can correctly determine the transmission timing of the corresponding channel, thereby solving the technical problem that the transmission time unit of the channel cannot be accurately determined in the scenario of channel repetition transmission.
