Mechanism for TB processing over multi-slot scheme
The present disclosure proposes configuration for TB processing over multi-slot, particularly Transmission Block over multi-slot (TBoMS) transmission. Specifically, such configuration for TBoMS may relate to at least one of size determination for TBoMS, scheduling for TBoMS transmission, resources determination and allocation for TBoMS transmission, and so on, and corresponding information related to such configuration can be acquired, set or determined appropriately, so that the TB processing over multi-slot can be performed accordingly.

at least one antenna;
at least one radio coupled to the at least one antenna; and
a processor coupled to the at least one radio;
wherein the wireless device is configured to:
acquire configuration information about Transmission Block over Multiple time-domain Resources (TBoMR);
determine a transmission block size (TBS) based on a number of slots for Transmission Block over Multiple Slot (TBoMS) transmission from a plurality of transmission occasions (TOs), wherein the number of slots comprises both consecutive uplink (UL) slots and non-consecutive UL slots; and
perform at least TBoMR transmission over time-domain resources based on the configuration information, wherein the time-domain resources are allocated based on the determined TBS.
2. The wireless device of claim 1 , wherein the configuration information further includes repetition type information about Time Domain Resource Allocation (TDRA) for the TBoMR transmission, and the wireless device is configured to:
perform the TBoMR transmission over the time-domain resources allocated according to the repetition type information.
3. The wireless device of claim 2 , wherein when the repetition type information indicates a first repetition type, and the time-domain resource allocation is based on at least one of the following:
a number of allocated symbols is the same in each slot as the time-domain resource,
all consecutive slots serve as the time-domain resources for the TBoMR transmission; and
all available slots serve as the time-domain resources for repetition in the TBoMR transmission.
4. The wireless device of claim 3 , wherein when the repetition type information indicates a second repetition type, and the time-domain resource allocation is based on at least one of the following:
the number of allocated symbols is different in each slot as the time-domain resource,
all consecutive slots serve as the time-domain resources for the TBoMR transmission; and
all available symbols serve as the time-domain resources for repetition in the TBoMR transmission.
5. The wireless device of claim 1 , wherein the configuration information further include information indicating whether a special time-domain resource is available for the TBoMR transmission, and the wireless device is configured to:
perform the TBoMR transmission over the special time-domain resource when the information indicates the special time-domain resource is available.
6. The wireless device of claim 1 , wherein the configuration information includes transmission mode information indicating the transmission mode of first TBoMS transmission, and
wherein the wireless device is further configured to: perform the first TBoMS transmission according to the transmission mode indicated by the transmission mode information.
7. The wireless device of claim 1 , wherein the configuration information includes information indicating whether re-transmission is enabled for TBoMS transmission or not implicitly or explicitly, and
wherein the wireless device is further configured to: when the re-transmission is enabled, perform a re-transmission of a first TBoMS transmission.
8. A method for a user equipment (UE), comprising:
acquiring configuration information about Transmission Block over Multiple time-domain Resources (TBoMR);
determining a transmission block size (TBS) based on a number of slots for Transmission Block over Multiple Slot (TBoMS) transmission from a plurality of transmission occasions (TOs), wherein the number of slots comprises both consecutive uplink (UL) slots and non-consecutive UL slots; and
performing at least TBoMR transmission over time-domain resources based on the configuration information, wherein the time-domain resources are allocated based on the determined TBS.
9. The method of claim 8 , wherein the configuration information further includes repetition type information about Time Domain Resource Allocation (TDRA) for the TBoMR transmission, and the method further comprising:
performing the TBoMR transmission over the time-domain resources allocated according to the repetition type information.
10. The method of claim 9 , wherein when the repetition type information indicates a first repetition type, and the time-domain resource allocation is based on at least one of the following:
a number of allocated symbols is the same in each slot as the time-domain resource,
all consecutive slots serve as the time-domain resources for the TBoMR transmission; and
all available slots serve as the time-domain resources for repetition in the TBoMR transmission.
11. The method of claim 10 , wherein when the repetition type information indicates a second repetition type, and the time-domain resource allocation is based on at least one of the following:
the number of allocated symbols is different in each slot as the time-domain resource,
all consecutive slots serve as the time-domain resources for the TBoMR transmission; and
all available symbols serve as the time-domain resources for repetition in the TBoMR transmission.
12. The method of claim 8 , wherein the configuration information further includes information indicating whether a special time-domain resource is available for the TBoMR transmission, and the method further comprising:
performing the TBoMR transmission over the special time-domain resource when the information indicates the special time-domain resource is available.
13. The method of claim 8 , wherein the configuration information includes transmission mode information indicating the transmission mode of first TBoMS transmission, and
wherein the method further comprises: performing the first TBoMS transmission according to the transmission mode indicated by the transmission mode information.
14. The method of claim 8 , wherein the configuration information includes information indicating whether re-transmission is enabled for TBoMS transmission or not implicitly or explicitly, and
wherein the method further comprises: when the re-transmission is enabled, performing a re-transmission of a first TBoMS transmission.
