[0013] In the related art, PUSCH retransmission type A employs a contiguous slot-based scheme, i.e., a terminal is configured to perform K retransmissions in K consecutive slots. Specifically, when the number of retransmissions is configured to be 16, for a TDD frame structure, such as 7D1S2U, i.e., a frame structure in which seven downlink subframes, one special subframe, and two uplink subframes are configured per frame, 16 retransmissions cover one subframe and six slots. Referring to FIG. 1, when one subframe and six slots each include two uplink slots, the number of retransmissions that can actually be performed is four. When the number of retransmissions is configured to be 32, the number of retransmissions that can actually be performed is eight. That is, when the number of retransmissions is configured to be 32, the number of retransmissions that can actually be performed is much smaller than the number configured by the network side due to the contiguous slot-based scheme, resulting in low uplink transmission efficiency.

[0014] Based on this, the uplink transmission method, device, terminal, and storage medium provided in the embodiments of the present application adopt an available slot scheme, in which the first terminal determines a slot in which the number of available symbols is equal to or greater than the specified number of symbols transmitted each time, or a slot in which the number of available symbols is equal to or greater than the specified number of symbols in each repeated transmission, as the first available slot for PUSCH transmission or repeated transmission, and performs PUSCH transmission or repeated transmission based on this, thereby avoiding a situation in which the actual number of transmissions or repeated transmissions is much smaller than the number configured on the network side, and improving uplink transmission efficiency.

[0015] The present application will now be described in more detail with reference to the figures and examples.

[0016] The embodiment of the present application provides an uplink transmission method applied to a first terminal, and as shown in FIG. 2, the uplink transmission method includes step 201.

[0017] In step 201, the first slot is determined.

[0018] Here, the first slot represents an available slot for transmission or repeated transmission of a PUSCH, and the number of available symbols in the first slot is equal to or greater than the number of symbols in the indicated each transmission or repeated transmission.

[0019] In the related art, the definition and processing method of the available slot are lacking. In principle, the definition of the available slot needs to consider whether to include a flexible slot, whether to consider a change in the flexible slot, and more specifically, whether to consider RRC configuration information, such as uplink and downlink slot configuration information, and whether to consider SFI. In consideration of the above, in the embodiment of the present application, the basic rule for determining the available slot is that the number of available symbols is equal to or greater than the number of symbols in the specified each transmission or repeated transmission. In this way, it can be ensured that the available resources in the determined available slot can satisfy the transmission or repeated transmission of the PUSCH.

[0020] In practical application, the first terminal determines the first slot based on the TDD configuration information, where the TDD configuration information includes, but is not limited to, tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. Furthermore, when considering the available resources of the available slot, the first terminal does not consider the following symbols as available resources of the available slot. That is, the available symbols are: Symbols carrying type 0-PDCCH CSS, and / or Flexible symbols carried by SSB are not included.

[0021] In practical application, determining the first slot based on the configuration information of TDD includes the following two situations:

[0022] In situation 1, the first slot and available resources on the first slot are determined based on the uplink slot and uplink symbol indicated by the TDD configuration information.

[0023] That is, only uplink slots and uplink symbols are considered as available resources of available slots.

[0024] In situation 2, the first slot and available resources on the first slot are determined based on the uplink slot, uplink symbol, flexible slot, and flexible symbol indicated by the TDD configuration information.

[0025] That is, when determining available slots, in addition to considering uplink slots and uplink symbols as available resources of available slots, whether flexible slots and flexible symbols are also considered as available resources of available slots is also considered.

[0026] In the above, it has been mentioned that the SFI is taken into consideration when determining available slots. In the embodiment of the present application, the indication of the SFI can be considered in two cases. One is to not consider the indication of the SFI when determining available slots, and then consider the influence of the SFI when performing collision processing for other configuration information. The other is to consider the indication of the SFI when determining available slots.

[0027] Here, the SFI may be an indication of a slot format based on Downlink Control Information (DCI) format 2_0.

[0028] Next, the process of determining available slots will be described in detail for situations where the SFI indication is not taken into account when determining available slots.

[0029] 1. Regarding the above situation 1, i.e., the situation in which the first slot and the available resources on the first slot are determined based on the uplink slot and uplink symbol indicated by the TDD configuration information, the first terminal does not need to consider the SFI when determining the available slot, i.e., it is considered that the SFI does not affect the determination of the available slot.

[0030] 2. Regarding the above situation 2, i.e., determining the first slot and available resources on the first slot based on the uplink slot, uplink symbol, flexible slot, and flexible symbol indicated by the TDD configuration information, First, it is determined whether a corresponding slot is the first slot based on the uplink slot, uplink symbol, flexible slot, and flexible symbol indicated by the TDD configuration information. If the number of available symbols in the corresponding slot is equal to or greater than the number of symbols for a designated individual PUSCH transmission or repeated transmission, i.e., if all the symbols for the designated individual PUSCH transmission or repeated transmission are uplink symbols or flexible symbols and all the symbols for the designated individual PUSCH transmission or repeated transmission are not occupied by other channels or signals and can be used for PUSCH transmission or repeated transmission, the slot is confirmed as an available slot, i.e., the first slot, and the corresponding designated symbols for the designated individual PUSCH transmission or repeated transmission are confirmed as available resources in the first slot.

[0031] Next, based on the above-mentioned qualification for the first slot, when the first terminal receives the first SFI, the first terminal can perform the following process.

[0032] The first SFI is not considered to affect the first terminal's determination of the first slot; and / or the first SFI is not expected to change the first slot determination by the first terminal; and / or When the first SFI instructs updating the flexible symbol to a downlink symbol, if the updated uplink symbol and / or flexible symbol cannot satisfy the transmission or repeated transmission of the PUSCH, count one repeated transmission for the corresponding first slot, and do not perform the transmission or repeated transmission of the PUSCH in the corresponding first slot; and / or When the first SFI instructs updating a flexible symbol to 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 slot, and the transmission or repeated transmission of the PUSCH is performed using only some of the resources.

[0033] Here, inability to fulfill the PUSCH transmission or repeated transmission means that the corresponding physical resources cannot fulfill the number or position of physical resources used for the specified PUSCH transmission or repeated transmission, and transmission on some resources means transmission on resources that do not overlap or collide or are not occupied by other transmissions.

[0034] For example, if the first SFI indicates a flexible symbol as an uplink symbol, or if the first SFI does not indicate any configuration update, the first terminal assumes that the SFI indicated by the base station will not change the first terminal's decision on available slots and available resources on the available slots, or the first terminal does not expect that the SFI indicated by the base station will change the first terminal's decision on available slots and available resources on the available slots. As another example, if the first SFI instructs the first terminal to update a flexible symbol to a downlink symbol, and at this time, the number of flexible symbols available for uplink transmission is reduced, and the updated uplink symbol and flexible symbol can still satisfy the indicated transmission or repeated transmission of a PUSCH, the first terminal still determines the corresponding slot as the first slot. If the updated uplink symbols and flexible symbols cannot satisfy the indicated PUSCH transmission or repeated transmission, the first terminal still determines the corresponding slot as the first slot, but does not transmit or repeat PUSCH in the first slot, but still counts one repeated transmission for the first slot, that is, adds 1 to the recorded number of repeated transmissions, or the first terminal transmits or repeats PUSCH in the available symbols of the first slot.

[0035] We now discuss in more detail the circumstances under which the SFI indication is taken into account when determining available slots.

[0036] In one embodiment, determining the first slot comprises: determining the first slot and available resources on the first slot based on an uplink slot, an uplink symbol, and a second SFI indicated by TDD configuration information; or determining the first slot and available resources on the first slot based on an uplink slot, an uplink symbol, a flexible slot, and a flexible symbol indicated by TDD configuration information and based on the first SFI.

[0037] Here, the second SFI represents the SFI that the first terminal last received before receiving the first DCI, and the first DCI is used to indicate transmission or repeated transmission of a PUSCH.

[0038] 1. Regarding the above situation 1, i.e., the situation where only the uplink slots and uplink symbols indicated by the TDD configuration information are considered, First, it is determined whether a corresponding slot is the first slot based on the uplink slot and uplink symbol indicated by the TDD configuration information and the uplink symbol indicated by the second SFI. If the number of available symbols in the corresponding slot is equal to or greater than the number of symbols specified for each PUSCH transmission or repeated transmission, i.e., if all available uplink symbols in the corresponding slot can be used for PUSCH transmission or repeated transmission, the slot is confirmed as an available slot, i.e., the first slot, and the corresponding available uplink symbol is confirmed as an available resource on the first slot.

[0039] Next, based on the above-mentioned determination of the first slot, if the first terminal receives the third SFI after receiving the second SFI, the first terminal can perform the following process.

[0040] The third SFI is not considered to change the first slot decision made by the first terminal, and / or The third SFI is not expected to change the first slot decision by the first terminal.

[0041] Furthermore, in this case, the uplink symbols indicated by the second SFI above include flexible symbols updated to the uplink symbols indicated by the second SFI, and are not updated to flexible symbols or downlink symbols.

[0042] Alternatively, when the first terminal receives a third SFI after receiving the second SFI, if the third SFI indicates that the uplink symbol indicated in the second SFI is updated to a flexible symbol or a downlink symbol, and if the updated uplink symbol and / or flexible symbol cannot satisfy the transmission or repeated transmission of the PUSCH, the transmission or repeated transmission of the PUSCH is not performed in the corresponding first slot, and one repeated transmission is counted for the corresponding first slot, or the transmission or repeated transmission of the PUSCH is performed using only some of the resources.

[0043] Here, inability to fulfill the PUSCH transmission or repeated transmission means that the corresponding physical resources cannot fulfill the number or position of physical resources used for the specified PUSCH transmission or repeated transmission, and transmission on some resources means transmission on resources that do not overlap or collide or are not occupied by other transmissions.

[0044] That is, when the third SFI indicates that the uplink symbol indicated in the second SFI is updated to a flexible symbol or a downlink symbol, the number of flexible symbols available for uplink transmission is reduced, and if the updated uplink symbol and flexible symbol cannot meet the transmission or repeated transmission of the indicated PUSCH, the first terminal still determines the corresponding slot as the first slot, but does not perform the transmission or repeated transmission of the PUSCH in the first slot, but still counts one repeated transmission for the first slot, i.e., adds 1 to the number of recorded repeated transmissions, or the first terminal transmits or repeats the PUSCH in the available symbols of the first slot.

[0045] 2. Regarding the above situation 2, that is, in addition to considering the uplink slots and uplink symbols indicated by the TDD configuration information, also considering the flexible slots and flexible symbols indicated by the TDD configuration information, First, it is determined whether a corresponding slot is the first slot based on the uplink slot, uplink symbol, flexible slot, and flexible symbol indicated by the TDD configuration information and the uplink symbol indicated by the second SFI. If the number of available symbols in the corresponding slot is equal to or greater than the number of symbols specified for each PUSCH transmission or repeated transmission, i.e., if all available uplink symbols and flexible symbols in the corresponding slot can be used for uplink transmission or repeated transmission, the slot is confirmed as an available slot, i.e., the first slot, and the corresponding available uplink symbols and flexible symbols are confirmed as available resources in the first slot.

[0046] Next, based on the above-mentioned determination of the first slot, if the first terminal receives the third SFI after receiving the second SFI, the first terminal can perform the following process.

[0047] The third SFI is not considered to change the first slot decision made by the first terminal, and / or The third SFI is not expected to change the first slot decision by the first terminal.

[0048] Alternatively, when the first terminal receives a third SFI after receiving the second SFI, if the third SFI indicates that the uplink symbol indicated in the second SFI is updated to a flexible symbol or a downlink symbol, and 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 slot, and the transmission or repeated transmission of the PUSCH is not performed in the corresponding first slot.

[0049] Here, the inability to satisfy the transmission or repeated transmission of the PUSCH means that the corresponding physical resources cannot satisfy the number or position of the physical resources used for the specified transmission or repeated transmission of the PUSCH. That is, when the third SFI updates the symbol state, the number of flexible symbols available for uplink transmission is reduced, and the updated uplink symbols and flexible symbols cannot satisfy the specified transmission or repeated transmission of the PUSCH, the first terminal still determines the corresponding slot as the first slot, but does not perform the transmission or repeated transmission of the PUSCH in the first slot, but still counts one repeated transmission for the first slot, that is, adds 1 to the number of recorded repeated transmissions, or the first terminal transmits or repeats the PUSCH in the remaining available resources.

[0050] In the related art, a CI indication can only be used for repetition type B and cannot cancel repetition type A. One condition for CI to be enabled is that the CI must be transmitted before the physical uplink control channel (PDCCH) scheduled by the corresponding PUSCH or sounding reference signal (SRS) transmission. However, considering that the corresponding PUSCH transmission or repetitive transmission may span a long period of time after adopting a scheme based on available slots, for example, in the case of scheduling based on available slots for a 7D1S2U frame structure, when the number of retransmissions is configured to be 16, the PUSCH transmission or repetitive transmission may span 80 slots, and the PDCCH corresponding to the scheduling or indication is transmitted far in advance. In this case, if a CI indication is still required to be transmitted before the indication corresponding to the transmission, it is difficult to implement.

[0051] Based on this, in one embodiment, the method further comprises: When a first CI is received when transmitting or repeating a PUSCH based on the determined first slot, the method includes canceling the transmission or repeating transmission of the corresponding PUSCH, counting one repeating transmission for the transmission or repeating transmission of the corresponding PUSCH, or transmitting or repeating a PUSCH using only some of the resources.

[0052] Here, the resource indicated by the first CI to be canceled overlaps with the transmission or repeated transmission of the corresponding PUSCH, or overlaps with the slot of the transmission or repeated transmission of the corresponding PUSCH. Also, performing transmission on some resources means performing transmission on resources that are not overlapped or collided with or are not occupied by other transmissions.

[0053] Here, when the terminal transmits or repeats a PUSCH based on an available slot, if the resource for which the received CI indicates cancellation includes a time-domain symbol or a frequency-domain physical resource block (PRB) that overlaps with the corresponding PUSCH transmission or repeat transmission, or overlaps with the slot for the corresponding PUSCH transmission or repeat transmission, the terminal cancels the corresponding PUSCH transmission or repeat transmission but still counts one repeat transmission for the first slot, i.e., adds 1 to the recorded number of repeat transmissions, or the first terminal performs the corresponding PUSCH transmission or repeat transmission in the remaining resources without overlap.

[0054] In one embodiment, the symbols for which the first CI indicates cancellation include a first symbol, a second symbol, and a symbol between the first symbol and the second symbol.

[0055] The first symbol represents the last symbol in which the PDCCH carrying the first CI is received, and the second symbol represents the first symbol after processing delay and time offset.

[0056] That is, the symbols indicated by the first CI to be cancelled start from the last symbol receiving the PDCCH indication carrying the first CI and end with the first symbol after processing delay and time offset. In practice, the base station and the terminal agree on the symbols indicated by the CI, thereby avoiding misunderstandings between the base station and the terminal, which can affect transmission efficiency.

[0057] In one embodiment, the PDCCH carrying the first CI indication does not need to be transmitted or received by the first terminal before the first DCI, where the first DCI is used to indicate transmission or repeated transmission of the PUSCH.

[0058] In practical application, many higher priority transmissions are defined in the protocol. For example, when the SFI updates the uplink or downlink transmission mode of the flexible slot, the impact of the update on the definition of the available slot needs to be further considered, and the indication of the CI and the transmission relationship between the SRS and the available slots need to be considered. In particular, since the SRS is transmitted in a special slot and occupies some symbols after the special slot, it is necessary to further consider how to handle the transmission relationship between the SRS and the special slot.

[0059] Generally, for the SRS processing problem, it is necessary to consider that the service transmission is a higher priority service for Ultra-Reliable Low-Latency Communication (URLLC). Based on this, in one embodiment, the priority of the PUSCH transmission or repeated transmission is high, and when determining the first slot, the method includes: Determining the third symbol, the fourth symbol, and / or the fifth symbol as available symbols.

[0060] Here, the third symbol represents a configurable SRS symbol or a configured SRS symbol. The fourth symbol represents a symbol of a designated PUSCH transmission or repeated transmission, and the network side triggers the first terminal to transmit aperiodic SRS using the fourth symbol. The fifth symbol represents a symbol of a designated PUSCH transmission or repeated transmission, and transmission of periodic and / or semi-persistent SRS using the fifth symbol is overlapped with the corresponding PUSCH transmission or repeated transmission.

[0061] Here, if the priority of PUSCH transmission or repeated transmission is high, for example, if the priority indication of PUSCH transmission or repeated transmission is 1 (priority index 1), or if PUSCH transmission or repeated transmission is for a relatively high-priority service such as a URLLC service, all symbols for which SRS is potentially configurable or symbols for which SRS is configured are considered to be capable of PUSCH transmission or repeated transmission. Therefore, when determining available slots, the position of the SRS symbol is not taken into consideration, and the corresponding symbol is considered to be capable of PUSCH transmission or repeated transmission. If the first terminal is triggered by the base station to transmit aperiodic SRS at the indicated PUSCH transmission or repeated transmission symbol, the first terminal still transmits or repeats PUSCH at the corresponding symbol, and does not transmit aperiodic SRS at the corresponding symbol. If periodic and / or semi-persistent SRS transmission overlaps with PUSCH transmission or repeated transmission, PUSCH transmission or repeated transmission is still performed at the corresponding resource.

[0062] In another embodiment, the priority of the transmission or repeated transmission of the PUSCH is low priority, and the method further comprises: When the first terminal is triggered by the network side to transmit aperiodic SRS, and the symbol for transmitting the aperiodic SRS overlaps with the symbol for the indicated PUSCH transmission or repeated transmission, cancel the corresponding PUSCH transmission or repeated transmission, count one repeated transmission for the corresponding PUSCH transmission or repeated transmission, or transmit or repeat the PUSCH using only some resources; or If the transmission of the periodic SRS overlaps with the corresponding PUSCH transmission or repeated transmission, performing the corresponding PUSCH transmission or repeated transmission.

[0063] Here, transmission on some resources means transmission on resources that do not overlap or collide, or that are not occupied by other transmissions.

[0064] Here, if the priority of the PUSCH transmission or repeated transmission is low, for example, if the priority indication of the PUSCH transmission or repeated transmission is 0 (priority index 0), or if the PUSCH transmission or repeated transmission is a service with a relatively low priority such as an enhanced mobile broadband (eMBB) service, in the first situation, the first terminal considers that all symbols for which SRS is configured will not be used for PUSCH transmission or repeated transmission, and in the second situation, the first terminal does not consider that SRS affects the definition of available slots, that is, all uplink symbols are considered to be available symbols even if SRS transmission is configured. Specifically, when the network side configures or instructs PUSCH transmission or repeated transmission, and the symbols of the instructed PUSCH transmission or repeated transmission overlap with the symbols of aperiodic SRS triggered by the network side to be transmitted to the first terminal, in order to ensure the transmission of the higher priority AP-SRS, the PUSCH transmission or repeated transmission is not performed for the corresponding symbol, but one repeated transmission is still counted for the symbol, that is, one is added to the recorded number of repeated transmissions; or the first terminal transmits PUSCH transmission or repeated transmission only on resources without overlap; or when the PUSCH transmission or repeated transmission overlaps with the transmission of periodic SRS, the PUSCH transmission or repeated transmission is given priority, that is, the periodic SRS is not transmitted.

[0065] In addition, in practical application, if the duration of PUSCH transmission or repeated transmission is relatively long and periodic SRS cannot be transmitted for a long time, the base station can trigger and transmit one non-periodic SRS to acquire the channel state.

[0066] In one embodiment, when the priority of the PUSCH transmission or repeated transmission is lower than a set priority and the first slot is determined, the method includes: determining a sixth symbol as an available symbol, wherein: The sixth symbol represents a symbol where semi-persistent SRS is configured and where semi-persistent SRS is not activated.

[0067] Here, for a symbol for which semi-persistent SRS is configured, if the semi-persistent SRS is not activated, the symbol is considered to be an available symbol for PUSCH transmission or repeated transmission, and if the corresponding semi-persistent SRS is activated, the symbol is considered not to be an available symbol for PUSCH transmission or repeated transmission.

[0068] In one embodiment, the method further comprises: If semi-persistent SRS is activated when transmitting or repeating a PUSCH in the sixth symbol, the method includes canceling the transmission or repeating of the corresponding PUSCH, counting one repeating transmission for the transmission or repeating of the corresponding PUSCH, or transmitting or repeating a PUSCH on only some resources.

[0069] Here, transmission on some resources means transmission on resources that do not overlap or collide, or that are not occupied by other transmissions.

[0070] If the transmission of the corresponding semi-persistent SRS is terminated at the time of transmission or repeated transmission of the PUSCH, the available slots determined by the first terminal when the semi-persistent SRS is activated are not affected.

[0071] In the embodiment of the present application, the PUSCH is transmitted or repeatedly transmitted based on the available slots, thereby avoiding the situation where the actual number of transmissions or repeated transmissions is much smaller than the number configured by the network side. For example, if 16 or 32 retransmissions are configured, 16 or 32 retransmission opportunities are actually obtained, which greatly improves uplink transmission efficiency.
