- the UE does not need to know the location information of the uplink and downlink subbands configured on the flexible symbol, that is, the UE does not know the frequency resource location of the uplink and downlink subbands. Then, if the UE determines to perform downlink transmission on the flexible symbol, the gNB should ensure that the UE is instructed to perform downlink reception only in the downlink subband configured with the flexible symbol. If the UE determines to perform uplink transmission on the flexible symbol, the gNB should ensure that the UE is instructed to perform uplink transmission only in the uplink subband configured with the flexible symbol.

Therefore, these downlink time slots and special time slots configured with uplink subbands are SBFD time slots.
- UEs with SBFD capability can clearly know the time-frequency position of each subband.
- method 2 has better flexibility in frequency resource scheduling, frequency protection interval configuration, and channel state information (CSI) measurement and reporting, but requires additional signaling to notify UEs with SBFD capability of the time-frequency position of the uplink and downlink subbands, which increases signaling overhead.
- the UE is visible to the uplink and downlink subbands configured on the downlink symbols, that is, the UE knows the frequency resource locations of the uplink and downlink subbands, and the UE performs downlink transmission on the downlink subbands of the downlink symbols and performs uplink transmission on the uplink subbands of the downlink symbols.

- Multi-slot PUCCH includes: PUCCH repetition.
- Step 1 Determine time domain resources.
- Multi-slot PUSCH/PUCCH time domain resources There are two methods for determining Multi-slot PUSCH/PUCCH time domain resources: one is the physical time slot counting method, and the other is the available time slot counting method. The following describes the two technical methods in detail.
- the first time slot counting method physical time slot counting method.
- the physical time slot can be understood as the time slot defined in the NR frame structure, and each physical time slot is included in the time slot count of Multi-slot PUSCH/PUCCH.
- the TDD uplink and downlink time slots are configured as DDSUU
- the network device indicates that the total number of time slots of Multi-slot PUSCH/PUCCH is 4, and the starting time slot is the 4th time slot in DDSUU (i.e., the first U time slot), then from this time slot onwards, each time slot will be included in the time slot count of Multi-slot PUSCH/PUCCH until the number of included time slots reaches the total number of time slots indicated by the network device, i.e., the fourth to eighth time slots in Figure 3 are included in the time slot count of Multi-slot PUSCH/PUCCH through this method.
- the time slots included in the Multi-slot PUSCH/PUCCH time slot count need to be further confirmed according to the collision rules whether Multi-slot PUSCH/PUCCH can be transmitted on the time slot.
- the conflict criteria include: if the symbol included in the Multi-slot PUSCH/PUCCH timeslot count overlaps with the downlink symbol of the semi-static configuration (tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated), even if it is a partial overlap, the Multi-slot PUSCH/PUCCH will be cancelled and transmitted in the timeslot where the overlapping symbol is located.
- the fifth and sixth timeslots are downlink timeslots and overlap with the symbols included in the Multi-slot PUSCH/PUCCH timeslot count. Therefore, in this method, Multi-slot PUSCH/PUCCH can only be transmitted in the fourth and fifth timeslots.
- the second time slot counting method available time slot counting method.
- the available time slots are determined based on the cell-level uplink and downlink configuration (tdd-UL-DL-ConfigurationCommon), the UE-level uplink and downlink configuration (tdd-UL-DL-ConfigurationDedicated), the SSB burst position (ssb-PositionsInBurst) and the time domain resource allocation (TDRA) information indicated by the DCI.
- tdd-UL-DL-ConfigurationCommon the cell-level uplink and downlink configuration
- tdd-UL-DL-ConfigurationDedicated the UE-level uplink and downlink configuration
- SSB burst position SSB burst position
- TDRA time domain resource allocation
- a time slot if the DCI indicates If at least one symbol in the symbol set allocated in a row of the TDRA table indicated overlaps with a downlink symbol indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated (if configured), or overlaps with an SSB symbol indicated by ssb-PositionsInBurst, the time slot is not an available time slot and is not counted in the time slot count of Multi-slot PUSCH/PUCCH; otherwise, the time slot is an available time slot and is counted in the time slot count of Multi-slot PUSCH/PUCCH.
- the TDD uplink and downlink configuration is DDSUU
- the network device indicates that the total number of time slots of Multi-slot PUSCH/PUCCH is 4, the starting time slot is the 4th time slot in DDSUU (i.e., the first U time slot), there is no SSB symbol in the time domain resources shown in Figure 4, there is no uplink symbol in the S time slot, and the D symbol in the S time slot coincides with a symbol in the TDRA table, then starting from the 4th time slot, only the uplink time slot is included in the time slot count of Multi-slot PUSCH/PUCCH until the number of included time slots reaches the total number of time slots indicated by the network device, 4.
- Multi-slot PUSCH/PUCCH can be transmitted on the 4th time slot, the 5th time slot, the 9th time slot, and the 10th time slot (i.e., all uplink time slots in Figure 4) shown in Figure 4.
- support for Multi-slot PUSCH/PUCCH based on physical slot count includes PUSCH repetition type A and PUCCH repetition.
- Support for Multi-slot PUSCH/PUCCH based on available slot count includes PUSCH repetition type A and PUSCH repetition across multi-slot transport block processing (TBoMS PUSCH repetition).
- Step 2 Determine frequency domain resources.
- the number of frequency resources allocated by Multi-slot PUSCH/PUCCH in each time slot of the time domain resources determined in step 1 is consistent, that is, the number of resource elements (RE) allocated in each time slot is the same.
- Step 3 Determine the number of information bits N info . It should be understood that the calculation of N info is an intermediate step in the calculation of the transport block size (TBS), which only involves the PUSCH but not the PUCCH.
- TBS transport block size
- the UE determines the number of REs N'RE allocated to PUSCH transmission in a PRB corresponding to a time slot, where N'RE satisfies the following formula:
- DMRS demodulation reference signal
- RS reference signal
- the UE determines the total number of REs N RE allocated for PUSCH transmission in a time slot, where N RE satisfies the following formula:
- N RE min(156,N' RE )*n PRB
- nPRB represents the number of allocated PRBs.
- N info N RE * R * Q m * v
- R represents the code rate
- Qm represents the modulation order
- v represents the number of multiple input multiple output (MIMO) layers.
- N info K*N RE *R*Q m *v
- K represents the number of time slots of TBoMS PUSCH
- N RE is the total number of REs allocated to PUSCH transmission in a time slot
- R represents the code rate
- Q m represents the modulation order
- v represents the number of multiple input multiple output (MIMO) layers.
- MIMO multiple input multiple output
- Step 4 Transmit Multi-slot PUSCH/PUCCH on the determined time-frequency resources according to N info .
- a Multi-slot PUSCH/PUCCH transmission scheme on SBFD is currently proposed: a Multi-slot PUSCH/PUCCH can only be transmitted on the SBFD timeslot, or can only be transmitted on the uplink timeslot; it cannot be transmitted on the SBFD timeslot and the uplink timeslot at the same time.

- a Multi-slot PUSCH/PUCCH can only be transmitted on X It can be transmitted on the time-frequency resources used for uplink transmission of the time slot, or can only be transmitted on the U time slot.
- X and U may simultaneously transmit a Multi-slot PUSCH/PUCCH, that is, the transmission scheme of Multi-slot PUSCH/PUCCH on SBFD cannot be implemented using the existing available time slot counting method and the physical time slot counting method.
- Multi-slot PUSCH/PUCCH cannot be sent on the time slot including the downlink symbol in the time slot included in the Multi-slot PUSCH/PUCCH time slot count.

- the following first introduces the concepts and processes involved in Type B PUSCH repetition.
- the network device can indicate to the terminal device the time domain resources of multiple nominal PUSCHs in the PUSCH repetition of type B, and the time domain resources of multiple nominal PUSCH repetitions are continuous in the time domain and have equal lengths.
- the network device can indicate to the terminal device the number K of nominal PUSCH repetitions, the starting symbol S of the time domain resource of the first nominal PUSCH repetition, and the number L of symbols contained in a nominal PUSCH repetition, and the number L of symbols contained in the time domain resource of each nominal PUSCH repetition is the same, where 0 ⁇ S ⁇ 13,1 ⁇ L ⁇ 14, and S+L>14 can be achieved.

- the terminal device determines the invalid symbol in each nominal PUSCH repetition time domain resource, and the remaining symbols can be considered as potential valid symbols.
- the terminal device can determine whether a symbol in a nominal PUSCH repetition time domain resource is an invalid symbol in the following way.
- the high-level parameter InvalidSymbolPattern configures a symbol-level bitmap, and a bit value of 1 indicates that the corresponding symbol is an invalid symbol.
- the terminal device does not send PUSCH repetitions on the actual PUSCH repetitions of a single symbol unless the duration L of the nominal PUSCH repetition indicated by the base station is a single symbol.

- two actual PUSCH repetitions are mapped to the fourth nominal PUSCH repetition, namely the sixth actual PUSCH repetition and the seventh actual PUSCH repetition. Since the time domain resources of the sixth actual PUSCH repetition are a single symbol and L is not equal to 1, the terminal device does not send PUSCH repetitions on the time domain resources of the sixth actual PUSCH repetition.
- the above-mentioned potential valid symbols may include both uplink symbols and SBFD symbols. Therefore, how to realize the currently proposed Multi-slot PUSCH transmission scheme on SBFD for Type B PUSCH repetition has become a problem that needs to be solved urgently.

- the time domain resource of the fifth actual PUSCH repetition is one time unit of the potential valid symbols in the time domain resource of the third nominal PUSCH repetition located in a time slot in the second time unit set
- the network device and the terminal device determine the first time unit type according to the same method, and then determine the second time unit set. The specific determination process is described above and will not be repeated here.
- this method adds a new method for determining invalid time units in the existing method for determining invalid time units, and this method is that the terminal device determines that all uplink time units in each time domain resource of nominal PUSCH repetition are invalid time, or the terminal device determines that all SBFD time units in each time domain resource of nominal PUSCH repetition are invalid time.
- This method can implement the transmission scheme of PUSCH repetition of repetition type B on SBFD, that is, PUSCH repetition of type B can only be transmitted on SBFD time slots, or can only be transmitted on uplink time slots, and cannot be transmitted on SBFD time slots and uplink time slots at the same time.

- the network device sends a second signaling to the terminal device.
- the terminal device receives the second signaling from the network device.

- time unit types of the time units for sending the first information and the second signal are different.
- the second signaling is DCI or RRC.
- the terminal device determines a fourth time unit set.
- the fourth time unit set is a set of time units in the K first time unit sets except the fifth time unit
- the fifth time unit includes time units of the second time unit type, wherein the second time unit type is an uplink time unit or an SBFD time unit and the second time unit type is different from the first time unit type.
- the fifth time unit here is an invalid time unit in the time domain resources of the K nominal PUSCH repetitions.

- the second signaling may carry third indication information, where the third indication information indicates the second time unit type.
- the second signaling does not carry the third indication information
- the terminal device can determine the second time unit type based on the first time unit type. For example, if the first time unit type is an SBFD time unit, then the second time unit type is an uplink time unit, and vice versa.
- the terminal device sends a second signal to the network device in the fourth time unit set or a subset of the fourth time unit set.
- the network device receives the second signal from the terminal device in the fourth time unit set or a subset of the fourth time unit set.

If L is equal to 1, the terminal device repeatedly sends the second signal on the time domain resources of all actual PUSCH repetitions in the K nominal PUSCH repetitions, and if L is greater than 1, the terminal device repeatedly sends the second signal on the time domain resources of all actual PUSCH repetitions in the K nominal PUSCH repetitions except the first type of actual PUSCH repetitions, wherein the first type of actual PUSCH repetition time domain resources includes one time unit.
- the existing protocol does not allow out-of-order scheduling, that is, it does not allow the second signal to be sent before the first signal is sent.
- the first signal can be transmitted in the second time unit set, and the second signal can be transmitted in the fourth time unit set. Then, when the start time unit of the time domain resource of the first actual PUSCH repetition determined based on the fourth time unit set is after the start time unit of the time domain resource of the first actual PUSCH repetition determined based on the second time unit set, and before the end time unit of the time domain resource of the last actual PUSCH repetition determined based on the second time unit set, the transmission of the second signal does not need to wait until the first signal is transmitted, thereby realizing out-of-order scheduling and reducing the waiting time for signal transmission.
- the second signaling in S1840 can also be modified to a second signaling used to instruct the terminal device to send a second signal on a continuous set of K sixth time units, the second signal is carried on the PUSCH repetition of repetition type B, the sixth time unit set is a time domain resource of a nominal repetition PUSCH, and the sixth time unit set is different from the first time unit set.
- the subsequent steps only need to replace the first time unit set with the sixth time unit set, which will not be repeated here.
- the present application also proposes another transmission scheme of Multi-slot PUSCH repetition on SBFD. That is, a Multi-slot PUSCH repetition can be transmitted simultaneously on the uplink time unit and the SBFD time unit, but when the first signal is transmitted on an SBFD time unit, the frequency range of the uplink subband on the SBFD time unit must completely cover the frequency range of the first signal, otherwise, the Multi-slot PUSCH repetition SBFD cannot be transmitted on the SBFD.

- the present application does not limit the position of the uplink subband of the SBFD time unit in the K first time unit sets, and the positions of the uplink subbands of these SBFD time units may be the same or different. For example, when the positions of the uplink subbands of these SBFD time units are the same, if the first frequency range overlaps with the frequency range of the downlink subband or the guard band of the SBFD time unit, the SBFD time unit is not included in the second time unit set.
- any invalid time unit determined based on the existing method of determining the invalid time unit is referred to as invalid time unit #1, and any invalid time unit determined based on the newly added method of determining the invalid time unit is referred to as invalid time unit #3.
