transmitting the configuration to the terminal device; and

receiving the TB that is transmitted from the terminal device according to the configuration, the group of N slots starting from a first slot being used by the terminal device in transmitting the TB, each slot of the group having at least L contiguous available symbols starting from a symbol indicated by S, and L contiguous available symbols starting from a symbol indicated by S in each slot of the group being used by the terminal device in transmitting the TB.

2 . The method of claim 1 , wherein the configuration indicates a type A TB over Multiple Slots (TBoMS) transmission, and wherein symbols at a same position in each of a number of slots are configured for transmitting the TB.

3 . The method of claim 2 , wherein the configuration contains parameters N when the type A TBoMS transmission is indicated in the configuration, and N indicates a number of slots.

4 . The method of claim 1 , wherein available symbols starting from a symbol indicated by S in any slot previous to the last slot of the group, which is not included in the group and has no less than X1 contiguous available symbols, are symbol-wise repetition of symbols in a particular slot of the group.

5 . The method of claim 3 , wherein the parameter N is indicated with one or more of the following:

N is signaled by a new Downlink Control Information, DCI, field;

N is added to a Time Domain Resource Assignment, TDRA, table and jointly encoded with TDRA field in DCI; or

N is Radio Resource Control, RRC, configured.

6 . The method of claim 1 , wherein transmission of the TB is scheduled with dynamic grant or configured grant.

7 . The method of claim 1 , where when a dynamic SFI is not configured, whether semi-static flexible symbols in any slot configured for transmitting the TB are available symbols is Radio Resource Control/Downlink Control Information (RRC/DCI) configured or predetermined.

8 . A method in a terminal device, the method comprising:

obtaining a configuration for transmitting a Transmission Block, TB, from a network device, the configuration indicating at least a transmission mode in which a single TB is allowed to be transmitted over more than one slot, the configuration containing parameters S and L, S indicating a starting symbol relative to a start of a first slot, L indicating a number of contiguous symbols in each slot, the configuration further comprising a parameter X1 indicating a minimum number of contiguous available symbols starting from a symbol indicated by S in each slot, and available symbols in any slot previous to the last slot of a group of N slots, which is not included in the group and has no less than X1 contiguous available symbols starting from a symbol indicated by S, being used by the terminal device in transmitting the TB;

determining resources for transmitting the TB according to the configuration; and

transmitting the TB to the network device over the determined resources, the group of N slots starting from a first slot being used by the terminal device in transmitting the TB, each slot of the group having at least L contiguous available symbols starting from a symbol indicated by S, and L contiguous available symbols starting from a symbol indicated by S in each slot of the group being used by the terminal device in transmitting the TB.

9 . The method of claim 8 , wherein the configuration indicates a type A TB over Multiple Slots (TBoMS) transmission, and wherein symbols at a same position in each of a number of slots are configured for transmitting the TB.

10 . The method of claim 9 , wherein the configuration contains parameter N when the type A TBoMS transmission is indicated in the configuration, N indicates a number of slots.

11 . The method of claim 8 , wherein available symbols starting from a symbol indicated by S in any slot previous to the last slot of the group, which is not included in the group and has no less than X1 contiguous available symbols, are symbol-wise repetition of symbols in a particular slot of the group.

12 . The method of claim 10 , wherein the parameter N is indicated with one or more of the following:

N is signaled by a new Downlink Control Information, DCI, field;

N is added to a Time Domain Resource Assignment, TDRA, table and jointly encoded with TDRA field in DCI; or

N is Radio Resource Control, RRC, configured.

13 . The method of claim 8 , wherein transmission of the TB is scheduled with dynamic grant or configured grant.

14 . The method of claim 8 , wherein when a dynamic SFI is configured and the transmission of the TB is scheduled with configured grant, whether semi-static flexible symbols in any slot configured for transmitting the TB are available symbols is Radio Resource Control/Downlink Control Information (RRC/DCI) configured or predetermined.

15 . A network device, comprising a transceiver, a processor and a memory, the memory comprising instructions executable by the processor whereby the network device is operative to:

determine a configuration for a terminal device to transmit a Transmission Block, TB, the configuration indicating at least a transmission mode in which a single TB is allowed to be transmitted over more than one slot, the configuration containing parameters S and L, S indicating a starting symbol relative to a start of a first slot, L indicating a number of contiguous symbols in each slot, the configuration further comprising a parameter X1 indicating a minimum number of contiguous available symbols starting from a symbol indicated by S in each slot, and available symbols in any slot previous to the last slot of a group of N slots, which is not included in the group and has no less than X1 contiguous available symbols starting from a symbol indicated by S, being used by the terminal device in transmitting the TB;

transmit the configuration to the terminal device; and

receive the TB that is transmitted from the terminal device according to the configuration, the group of N slots starting from a first slot being used by the terminal device in transmitting the TB, each slot of the group having at least L contiguous available symbols starting from a symbol indicated by S, and L contiguous available symbols starting from a symbol indicated by S in each slot of the group being used by the terminal device in transmitting the TB.

16 . A terminal device, comprising a transceiver, a processor and a memory, the memory comprising instructions executable by the processor whereby the terminal device is operative to:
