Transport block transmission using different spatial parameters
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine a first set of parameters associated with a first transport block (TB) repetition of a TB and a second set of parameters associated with a second TB repetition of the TB; and determine a TB size of the TB based at least in part on the first set of parameters, the second set of parameters, or both the first set of parameters and the second set of parameters. Numerous other aspects are provided.
1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving a grant for a first transport block (TB) repetition, wherein the grant indicates a first mini-slot in which the first TB repetition is scheduled;
receiving an indication of one or more spatial parameters corresponding to one or more subsequent TB repetitions; and
determining one or more subsequent mini-slots, that occur after the first mini-slot, in which the one or more subsequent TB repetitions are scheduled based at least in part on a mini-slot pattern configuration or one or more parameters of the first TB repetition.
2. The method of claim 1 , further comprising receiving the mini-slot pattern configuration, wherein the mini-slot pattern configuration indicates a pattern of mini-slots, for a time period, associated with TB repetition.
3. The method of claim 2 , wherein the mini-slot pattern configuration indicates a respective set of symbols occupied by each mini-slot included in the pattern of mini-slots.
4. The method of claim 3 , wherein the respective set of symbols is indicated by at least one of:
a starting symbol and a number of symbols for the respective set of symbols, or
the starting symbol and an ending symbol for the respective set of symbols.
5. The method of claim 1 , wherein a set of parameters, indicated in the grant for the first TB repetition, are used for the one or more subsequent TB repetitions.
6. The method of claim 5 , wherein the set of parameters includes at least one of:
a modulation and coding scheme,
a frequency domain allocation,
a time domain allocation,
a starting symbol of the first TB repetition,
a length of the first TB repetition, or
a combination thereof.
7. The method of claim 1 , further comprising receiving an indication of one or more redundancy versions corresponding to the one or more subsequent TB repetitions.
8. The method of claim 7 , wherein the indication is received in the grant or in a radio resource control (RRC) message.
9. The method of claim 1 , wherein a TB size for the first TB repetition and the one or more subsequent TB repetitions is determined based at least in part on a set of parameters associated with the first TB repetition.
10. The method of claim 1 , further comprising:
transmitting the first TB repetition, in the first mini-slot, and the one or more subsequent TB repetitions in the one or more subsequent mini-slots, or
receiving the first TB repetition, in the first mini-slot, and the one or more subsequent TB repetitions in the one or more subsequent mini-slots.
11. A method of wireless communication performed by a base station, comprising:
transmitting a grant for a first TB repetition, wherein the grant indicates a first mini-slot in which the first TB repetition is scheduled;
transmitting an indication of one or more spatial parameters corresponding to one or more subsequent TB repetitions; and
scheduling the one or more subsequent TB repetitions in one or more subsequent mini-slots that occur after the first mini-slot, wherein the one or more subsequent mini-slots are determined based at least in part on a mini-slot pattern configuration or one or more parameters of the first TB repetition.
12. A wireless communication device for wireless communication,
comprising: memory; and
one or more processors, coupled to the memory, configured to:
receive a grant for a first transport block (TB) repetition, wherein the grant indicates a first mini-slot in which the first TB repetition is scheduled;
receive an indication of one or more spatial parameters corresponding to one or more subsequent TB repetitions; and
determine one or more subsequent mini-slots, that occur after the first mini-slot, in which the one or more subsequent TB repetitions are scheduled based at least in part on a mini-slot pattern configuration or one or more parameters of the first TB repetition.
13. The wireless communication device of claim 12 , wherein the one or more processors are further configured to:
receive the mini-slot pattern configuration, wherein the mini-slot pattern configuration indicates a pattern of mini-slots, for a time period, associated with TB repetition.
14. The wireless communication device of claim 13 , wherein the mini-slot pattern configuration indicates a respective set of symbols occupied by each mini-slot included in the pattern of mini-slots.
15. The wireless communication device of claim 14 , wherein the respective set of symbols is indicated by at least one of:
a starting symbol and a number of symbols for the respective set of symbols, or
the starting symbol and an ending symbol for the respective set of symbols.
16. The wireless communication device of claim 12 , wherein a set of parameters, indicated in the grant for the first TB repetition, are used for the one or more subsequent TB repetitions.
17. The wireless communication device of claim 16 , wherein the set of parameters includes at least one of:
a modulation and coding scheme,
a frequency domain allocation,
a time domain allocation,
a starting symbol of the first TB repetition,
a length of the first TB repetition, or
a combination thereof.
18. The wireless communication device of claim 12 , wherein the one or more processors are further configured to:
receive an indication of one or more redundancy versions corresponding to the one or more subsequent TB repetitions.
19. The wireless communication device of claim 12 , wherein a TB size for the first TB repetition and the one or more subsequent TB repetitions is determined based at least in part on a set of parameters associated with the first TB repetition.
20. The wireless communication device of claim 12 , wherein the one or more processors are further configured to:
