[0060] In the related art, the retransmission type A of PUSCH adopts a continuous time slot-based manner, that is, the terminal is configured to perform K times of retransmission on K continuous time slots. Specifically, when the retransmission number is configured to be 16 times, for a TDD frame structure, such as 7D1S2U, that is, a frame structure in which 7 downlink subframes, 1 special subframe and 2 uplink subframes are configured in each frame, the 16 times of retransmission cover one subframe plus 6 time slots. Referring to Figure 1 In the case where one subframe and 6 time slots each contain 2 uplink time slots, the actual number of retransmissions that can be performed is 4 times. When the retransmission number is configured to be 32 times, the actual number of retransmissions that can be performed is 8 times. That is, the continuous time slot-based manner causes the actual number of retransmissions to be much smaller than the number of retransmissions configured by the network side, and the uplink transmission efficiency is low.

[0061] Based on this, in the uplink transmission method, device, terminal and storage medium provided by the embodiments of the present application, the available time slot-based manner is adopted, the first terminal determines, as the first time slot available for the transmission or repeated transmission of PUSCH, a time slot in which the number of available symbols is greater than or equal to the number of symbols indicated for each transmission or each repeated transmission, and performs the transmission or repeated transmission of PUSCH based on this, thereby avoiding the case where the actual number of transmissions or repeated transmissions is much smaller than the number of transmissions or repeated transmissions configured by the network side, and improving the uplink transmission efficiency.

[0062] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0063] The embodiments of the present application provide an uplink transmission method applied to a first terminal, as shown in Fig. 1, which comprises the following steps. Figure 2

[0064] Step 201: determining a first time slot.

[0065] The first time slot represents a time slot available for the transmission or repeated transmission of PUSCH; the number of symbols available for the first time slot is greater than or equal to the number of symbols indicated for each transmission or repeated transmission.

[0066] ​In the related art, there is a lack of relevant definitions and processing methods for available slots. For the definition of available slots, the following considerations need to be made in principle: whether to consider including flexible slots, whether to consider changes in flexible slots, more specifically, whether to consider RRC configuration information such as uplink and downlink slot configuration information, and whether to consider SFI and the like. In view of the above considerations, in the embodiments of the present application, the number of available symbols is greater than or equal to the number of symbols indicated for each transmission or repeated transmission, which is used as a basic criterion for determining available slots. In this way, it can be ensured that the available resources on the determined available slots can meet the transmission or repeated transmission of PUSCH.

[0067] In actual application, the first terminal determines the first slot based on the configuration information of TDD, wherein the configuration information of TDD includes but is not limited to tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. In addition, when considering the available resources of the available slots, the first terminal does not consider the following symbols as available resources of the available slots, that is, the available symbols do not include the following symbols:

[0068] symbols carrying type 0-PDCCH CSS; and / or,

[0069] flexible symbols carrying SSB.

[0070] In actual application, the determination of the first slot based on the configuration information of TDD includes the following two cases:

[0071] Case one: the first slot and the available resources on the first slot are determined based on the uplink slots and uplink symbols indicated in the configuration information of TDD.

[0072] That is, only the uplink slots and uplink symbols are considered as available resources of the available slots.

[0073] Case two: the first slot and the available resources on the first slot are determined based on the uplink slots, uplink symbols, flexible slots and flexible symbols indicated in the configuration information of TDD.

[0074] That is, in addition to considering the uplink slots and uplink symbols as available resources of the available slots, whether to consider the flexible slots and flexible symbols as available resources of the available slots is also considered when determining the available slots.

[0075] The above-mentioned consideration of SFI when determining available time slots can also be considered in two cases in embodiments of the present application: one is not considering the indication of SFI when determining available time slots, and further considering the impact of SFI when subsequently processing conflicts of other configuration information; and the other is considering the indication of SFI when determining available time slots.

[0076] Here, the SFI can be an indication of a slot format based on a downlink control information (DCI) format 2_0.

[0077] Next, for the case of not considering the indication of SFI when determining available time slots, the determination process of available time slots is described in detail:

[0078] 1. For the above-mentioned case one, i.e., determining the first time slot and the available resources on the first time slot based on the uplink time slots and uplink symbols indicated in the TDD configuration information, the first terminal can not consider the SFI when determining the available time slots, that is, it is considered that the SFI will not affect the determination of the available time slots.

[0079] 2. For the above-mentioned case two, i.e., determining the first time slot and the available resources on the first time slot based on the uplink time slots, uplink symbols, flexible time slots and flexible symbols indicated in the TDD configuration information:

[0080] First, based on the uplink time slots, uplink symbols, flexible time slots and flexible symbols indicated in the TDD configuration information, it is determined whether the corresponding time slot is the first time slot. When the number of available symbols in the corresponding time slot is greater than or equal to the number of symbols of the indicated PUSCH transmission or repeated transmission each time, that is, the symbols of the indicated PUSCH transmission or repeated transmission each time are all uplink symbols or flexible symbols, and the symbols of the indicated PUSCH transmission or repeated transmission each time are not occupied by other channels or signals and can be used for PUSCH transmission or repeated transmission, the time slot is confirmed as an available time slot, i.e., the first time slot, and the corresponding indicated symbols of the PUSCH transmission or repeated transmission each time are confirmed as available resources on the first time slot.

[0081] Secondly, based on the above-mentioned identification of the first time slot, when the first terminal receives the first SFI, the first terminal can perform the following processing:

[0082] it is considered that the first SFI does not affect the determination of the first time slot by the first terminal; and / or,

[0083] it is not expected that the first SFI will change the determination of the first time slot by the first terminal; and / or,

[0084] In a case where the first SFI indicates that the flexible symbol is updated as a downlink symbol, if the updated uplink symbol and / or flexible symbol cannot satisfy the transmission or repeated transmission of the PUSCH, one repeated transmission is counted for the corresponding first time slot, and no transmission or repeated transmission of the PUSCH is performed on the corresponding first time slot; and / or,

[0085] In a case where the first SFI indicates that the flexible symbol is updated as a downlink symbol, if the updated uplink symbol and / or flexible symbol cannot satisfy the transmission or repeated transmission of the PUSCH, one repeated transmission is counted for the corresponding first time slot, and only partial resource is used for the transmission or repeated transmission of the PUSCH.

[0086] In a case where the first SFI indicates that the flexible symbol is updated as a downlink symbol, if the updated uplink symbol and / or flexible symbol cannot satisfy the transmission or repeated transmission of the PUSCH, one repeated transmission is counted for the corresponding first time slot, and no transmission or repeated transmission of the PUSCH is performed on the corresponding first time slot; and / or,

[0087] For example, the first SFI indicates that the flexible symbol is an uplink symbol or the first SFI does not indicate any configuration update, the first terminal considers that the SFI indicated by the base station will not change the judgment of the first terminal on the available time slot and the available resource on the available time slot, or the first terminal does not expect that the SFI indicated by the base station will change the judgment of the first terminal on the available time slot and the available resource on the available time slot. For another example, the first SFI indicates that the flexible symbol is updated as a downlink symbol, at this time, the number of flexible symbols available for uplink transmission is reduced, then, if the updated uplink symbol and flexible symbol can still satisfy the indicated transmission or repeated transmission of the PUSCH, the first terminal still determines the corresponding time slot as the first time slot; if the updated uplink symbol and flexible symbol cannot satisfy the indicated transmission or repeated transmission of the PUSCH, the first terminal still determines the corresponding time slot as the first time slot, but no transmission or repeated transmission of the PUSCH is performed on the first time slot, but one repeated transmission is still counted for the first time slot, that is, the number of recorded repeated transmissions is increased by 1, or the first terminal performs the transmission or repeated transmission of the PUSCH on the available symbol of the first time slot.

[0088] Next, a case where the indication of the SFI is considered when determining the available time slot is described in detail.

[0089] In an embodiment, the determination of the first time slot comprises:

[0090] the uplink time slot, the uplink symbol and the second SFI indicated by the configuration information of the TDD are used to determine the first time slot and the available resource on the first time slot; or,

[0091] an uplink slot, an uplink symbol, a flexible slot, and a flexible symbol indicated by the configuration information of the TDD, and the first time slot and available resources on the first time slot based on the first SFI.

[0092] The second SFI indicates an SFI last received by the first terminal before the first DCI is received.

[0093] 1. In case 1 above, only considering the uplink slot and the uplink symbol indicated by the configuration information of the TDD:

[0094] First, based on the uplink slot and the uplink symbol indicated by the configuration information of the TDD and the uplink symbol indicated by the second SFI, it is determined whether the corresponding time slot is the first time slot. When the number of available symbols in the corresponding time slot is greater than or equal to the number of symbols indicated for each transmission or repeated transmission of PUSCH, i.e., all available uplink symbols in the corresponding time slot can be used for transmission or repeated transmission of PUSCH, the time slot is confirmed as an available time slot, i.e., the first time slot, and the corresponding available uplink symbols are confirmed as available resources on the first time slot.

[0095] Second, based on the above determination of the first time slot, when the first terminal receives a third SFI after receiving the second SFI, the first terminal can perform the following processing:

[0096] it is considered that the third SFI does not change the determination of the first time slot by the first terminal; and / or,

[0097] it is not expected that the third SFI will change the determination of the first time slot by the first terminal.

[0098] Further, in this case, the uplink symbols indicated by the second SFI, including the flexible symbols updated as uplink symbols by the second SFI, will not be updated as flexible symbols or downlink symbols.

[0099] Or, when the first terminal receives a third SFI after receiving the second SFI, in the case where the third SFI indicates that the uplink symbols indicated in the second SFI are updated as flexible symbols or downlink symbols, if the updated uplink symbols and / or flexible symbols cannot meet the transmission or repeated transmission of PUSCH, no transmission or repeated transmission of PUSCH is performed on the corresponding first time slot and one repeated transmission is counted for the corresponding first time slot, or only partial resources are used for transmission or repeated transmission of PUSCH.

[0100] In the case that the PUSCH transmission or the repeated transmission cannot be satisfied, it means that the corresponding physical resource cannot satisfy the indicated number or position of the physical resource for the PUSCH transmission or the repeated transmission; and in the case that the transmission is performed on the partial resource, it means that the transmission is performed on the resource without overlapping or conflict, or without being occupied by other transmission.

[0101] That is, in the case that the third SFI indicates to update the uplink symbol indicated in the second SFI as a flexible symbol or a downlink symbol, the number of the flexible symbols available for the uplink transmission is reduced, and if the updated uplink symbol and the flexible symbol cannot satisfy the indicated PUSCH transmission or repeated transmission, the first terminal still determines the corresponding time slot as the first time slot, but does not perform the PUSCH transmission or repeated transmission on the first time slot, but still counts the first time slot as one repeated transmission, that is, adds 1 to the recorded number of repeated transmissions, or the first terminal performs the PUSCH transmission or repeated transmission on the available symbols of the first time slot.

[0102] 2. In the case two above, in addition to considering the uplink time slot and the uplink symbol indicated in the TDD configuration information, the flexible time slot and the flexible symbol indicated in the TDD configuration information are also considered:

[0103] Firstly, based on the uplink time slot, the uplink symbol, the flexible time slot and the flexible symbol indicated in the TDD configuration information, and the uplink symbol indicated in the second SFI, it is determined whether the corresponding time slot is the first time slot. When the number of available symbols in the corresponding time slot is greater than or equal to the number of symbols indicated for each PUSCH transmission or repeated transmission, that is, the available uplink symbol and the flexible symbol in the corresponding time slot can be used for the uplink transmission or repeated transmission, the time slot is confirmed as the available time slot, that is, the first time slot, and the available uplink symbol and the flexible symbol are confirmed as the available resource in the first time slot.

[0104] Secondly, based on the above determination of the first time slot, when the first terminal receives the third SFI after receiving the second SFI, the first terminal can perform the following processing:

[0105] it is considered that the third SFI does not change the determination of the first time slot by the first terminal; and / or,

[0106] it is not expected that the third SFI will change the determination of the first time slot by the first terminal.

[0107] Or, when the first terminal receives a third SFI after receiving the second SFI, in the case that the third SFI indicates that the uplink symbol indicated in the second SFI is updated as a flexible symbol or a downlink symbol, if the updated uplink symbol and / or flexible symbol cannot satisfy the transmission or repeated transmission of PUSCH, one repeated transmission is counted for the corresponding first time slot and no transmission or repeated transmission of PUSCH is performed on the corresponding first time slot.

[0108] In the case that the updated uplink symbol and / or flexible symbol cannot satisfy the transmission or repeated transmission of PUSCH, it means that the corresponding physical resource cannot satisfy the number or position of the physical resource indicated for the transmission or repeated transmission of PUSCH; that is, due to the update of the symbol state by the third SFI, the number of flexible symbols available for uplink transmission is reduced, and the updated uplink symbol and flexible symbol cannot satisfy the indicated transmission or repeated transmission of PUSCH, so the first terminal still determines the corresponding time slot as the first time slot, but no transmission or repeated transmission of PUSCH is performed on the first time slot, but one repeated transmission is still counted for the first time slot, that is, the number of recorded repeated transmissions is increased by 1, or the first terminal performs the transmission or repeated transmission of PUSCH on the remaining available resources.

[0109] In the related art, the indication of CI can only be used for repetition type B, and cannot be used for cancellation of repetition type A. One condition for the CI to take effect is that the CI is sent before the corresponding physical uplink control channel (PDCCH) scheduling the transmission of PUSCH or SRS. However, considering that the available time slot based method is adopted, the transmission or repeated transmission of PUSCH can span a very long time, for example, for a 7D1S2U frame structure, if the available time slot based scheduling is adopted, when the number of retransmissions is configured to be 16 times, the transmission or repeated transmission of PUSCH can span 80 time slots, and the corresponding scheduling or indication PDCCH has been sent very early. At this time, if the indication of CI is still required to be sent before the corresponding transmission indication, it is difficult to implement.

[0110] Based on this, in an embodiment, the method further comprises:

[0111] In the case that a first CI is received when the transmission or repeated transmission of PUSCH is performed based on the determined first time slot, the corresponding transmission or repeated transmission of PUSCH is cancelled and one repeated transmission is counted for the corresponding transmission or repeated transmission of PUSCH, or the transmission or repeated transmission of PUSCH is only performed on part of the resources.

[0112] The first CI indicates that the canceled resource overlaps with the transmission or repeated transmission of the corresponding PUSCH, or overlaps with the time slot of the transmission or repeated transmission of the corresponding PUSCH. In addition, the transmission on the partial resource means that there is no overlap or conflict, or the transmission on the resource not occupied by other transmissions.

[0113] Here, when the terminal performs the transmission or repeated transmission of the PUSCH based on the available time slot, if the received CI indicates that the canceled resource, including the symbol in the time domain or the physical resource block (PRB) in the frequency domain, overlaps with the transmission or repeated transmission of the corresponding PUSCH, or overlaps with the time slot of the transmission or repeated transmission of the corresponding PUSCH, the transmission or repeated transmission of the corresponding PUSCH is canceled, but one repeated transmission is still counted for the first time slot, that is, the number of recorded repeated transmissions is increased by 1, or the first terminal performs the transmission or repeated transmission of the corresponding PUSCH on the remaining resource without overlap.

[0114] In an embodiment, the first CI indicates that the canceled symbol includes a first symbol, a second symbol, and a symbol between the first symbol and the second symbol.

[0115] The first symbol represents the last symbol of the received PDCCH carrying the first CI, and the second symbol represents the first symbol after the processing delay and the time offset.

[0116] That is, the first CI indicates the canceled symbol, from the last symbol indicated by the received PDCCH carrying the first CI to the first symbol after the processing delay and the time offset. In actual application, the base station and the terminal agree on the symbol indicated by the CI, so as to avoid inconsistent understanding of the base station and the terminal and affect the transmission efficiency.

[0117] In an embodiment, the PDCCH carrying the first CI indication does not need to be sent before or received by the first terminal before the first DCI, wherein the first DCI is used to indicate the transmission or repeated transmission of the PUSCH.

[0118] In actual application, many higher priority transmissions are defined in the early protocol, such as the SFI updates the transmission mode of the uplink or downlink of the flexible time slot, and then the influence of the update on the definition of the available time slot needs to be further considered, and the indication of the CI and the transmission relationship between the SRS and the available time slot need to be considered. In particular, the SRS is transmitted in a special time slot, and occupies the last several symbols of the special time slot, so how to process the transmission relationship between the SRS and the special time slot also needs to be considered.

[0119] Generally, for the processing problem of SRS, it needs to be considered that the service transmission is higher priority service for Ultra-Reliable Low-Latency Communication (URLLC). Based on this, in an embodiment, the priority of the transmission or repeated transmission of PUSCH is high priority; when determining the first time slot, the method comprises:

[0120] The third symbol, the fourth symbol and / or the fifth symbol are determined as available symbols.

[0121] The third symbol represents a symbol in which SRS can be configured or a symbol in which SRS is configured; the fourth symbol represents a symbol in which the transmission or repeated transmission of PUSCH is indicated and the network side triggers the first terminal to send aperiodic SRS on the fourth symbol; and the fifth symbol represents a symbol in which the transmission or repeated transmission of PUSCH is indicated and the transmission of periodic and / or semi-persistent SRS on the fifth symbol overlaps with the transmission or repeated transmission of corresponding PUSCH.

[0122] Here, when the priority of the transmission or repeated transmission of PUSCH is high priority, for example, the priority index of the transmission or repeated transmission of PUSCH is 1, or the transmission or repeated transmission of PUSCH is a service with higher priority, such as a URLLC service, all potential symbols in which SRS can be configured or symbols in which SRS is configured are considered to be able to perform the transmission or repeated transmission of PUSCH, so that when determining the available time slot, the position of the symbol of SRS is not considered, and it is considered that the corresponding symbol can perform the transmission or repeated transmission of PUSCH; if the first terminal is triggered by the base station to send aperiodic SRS on the symbol in which the transmission or repeated transmission of PUSCH is indicated, the corresponding symbol still performs the transmission or repeated transmission of PUSCH, and the first terminal does not send aperiodic SRS on the corresponding symbol; if the transmission of periodic and / or semi-persistent SRS overlaps with the transmission or repeated transmission of PUSCH, the transmission or repeated transmission of PUSCH is still performed on the corresponding resource.

[0123] In another embodiment, the priority of the transmission or repeated transmission of PUSCH is low priority; the method further comprises:

[0124] In the case where the network side triggers the first terminal to send aperiodic SRS, and the symbol in which aperiodic SRS is sent overlaps with the symbol in which the transmission or repeated transmission of PUSCH is indicated, the corresponding transmission or repeated transmission of PUSCH is cancelled and counted as one repeated transmission for the corresponding transmission or repeated transmission of PUSCH, or the transmission or repeated transmission of PUSCH is only performed on part of the resource; or,

[0125] In a case where the transmission of the periodic SRS overlaps with the corresponding PUSCH transmission or repeated transmission, the corresponding PUSCH transmission or repeated transmission is performed.

[0126] wherein the transmission on the partial resources means that there is no overlap or no conflict, or the transmission on the resources not occupied by other transmissions.

[0127] Here, when the priority of the transmission or repeated transmission of the PUSCH is a low priority, for example, the priority index of the transmission or repeated transmission of the PUSCH is 0, or the transmission or repeated transmission of the PUSCH is a service with a lower priority, such as an enhanced mobile broadband (eMBB) service, in one case, the first terminal considers that all the symbols configured with the SRS are not used for the transmission or repeated transmission of the PUSCH; in the second case, the first terminal does not consider that the SRS will affect the definition of available slots, that is, all the uplink symbols are considered to be available symbols even if the transmission of the SRS is configured. Specifically: when the network side configures or indicates the transmission or repeated transmission of the PUSCH, and the indicated symbols of the transmission or repeated transmission of the PUSCH overlap with the symbols of the aperiodic SRS triggered by the network side for the first terminal to send, in order to ensure the transmission of the AP-SRS with a higher priority, no transmission or repeated transmission of the PUSCH is performed on the corresponding symbols, but the symbol is still counted once for the repeated transmission, that is, the number of recorded repeated transmissions is increased by 1, or the first terminal only performs the transmission or repeated transmission of the PUSCH on the resources without overlap; or when the transmission or repeated transmission of the PUSCH overlaps with the transmission of the periodic SRS, the transmission or repeated transmission of the PUSCH is given priority, that is, the periodic SRS is not transmitted.

[0128] In addition, in actual application, if the duration of the transmission or repeated transmission of the PUSCH is long, causing the periodic SRS to be unable to be transmitted for a long time, the base station can trigger an aperiodic SRS to be transmitted and obtain the channel state.

[0129] In an embodiment, the priority of the transmission or repeated transmission of the PUSCH is lower than a set priority; in the determination of the first slot, the method comprises:

[0130] The sixth symbol is determined as an available symbol; wherein,

[0131] The sixth symbol represents a symbol on which a semi-persistent SRS is configured and the semi-persistent SRS is not activated.

[0132] Here, for a symbol configured with a semi-persistent SRS, if the semi-persistent SRS is not activated, the symbol is considered as an available symbol for transmission or repeated transmission of PUSCH; if the corresponding semi-persistent SRS is activated, the symbol is considered as an unavailable symbol for transmission or repeated transmission of PUSCH.

[0133] In an embodiment, the method further comprises:

[0134] In a case where a semi-persistent SRS is activated when transmission or repeated transmission of PUSCH is performed on the sixth symbol, the corresponding transmission or repeated transmission of PUSCH is cancelled and counted as one repeated transmission for the corresponding transmission or repeated transmission of PUSCH, or the transmission or repeated transmission of PUSCH is performed only on partial resources.

[0135] Wherein, performing transmission on partial resources means performing transmission on resources without overlapping or conflict, or resources not occupied by other transmissions.

[0136] If the corresponding semi-persistent SRS has been transmitted when transmission or repeated transmission of PUSCH is performed, the available time slots determined by the first terminal when the semi-persistent SRS is activated are not affected.

[0137] In the embodiments of the present application, the transmission or repeated transmission of PUSCH is performed based on the available time slots, which avoids the situation that the actual number of times of transmission or repeated transmission is much less than the number of times of retransmission configured by the network side. For example, in a case where 16 or 32 times of retransmission is configured, 16 or 32 times of retransmission opportunities will be actually obtained, which greatly improves the uplink transmission efficiency.
