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.

receiving an indication of a first set of symbols and a second set of symbols in which a single communication is scheduled, wherein the single communication does not include multiple repetitions of a transport block; and
transmitting or receiving the single communication in the first set of symbols and the second set of symbols using a first spatial parameter for the first set of symbols and a second spatial parameter for the second set of symbols.
2 . The method of claim 1 , wherein the indication is an implicit indication based at least in part on a first symbol of a first demodulation reference signal (DMRS) and a second symbol of a second DMRS.
3 . The method of claim 2 , wherein the first symbol is a starting symbol of the first set of symbols and the second symbol is a starting symbol of the second set of symbols.
4 . The method of claim 1 , wherein downlink control information indicates at least one of the first spatial parameter, the second spatial parameter, or the first set of symbols and the second set of symbols in which the single communication is scheduled.
5 . The method of claim 1 , wherein the first set of symbols and the second set of symbols are contiguous.

a combination thereof.
7 . The method of claim 1 , wherein the first spatial parameter is different than the second spatial parameter.
8 . A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to cause the UE to:
receive an indication of a first set of symbols and a second set of symbols in which a single communication is scheduled, wherein the single communication does not include multiple repetitions of a transport block; and
transmit or receiving the single communication in the first set of symbols and the second set of symbols using a first spatial parameter for the first set of symbols and a second spatial parameter for the second set of symbols.
9 . The UE of claim 8 , wherein the indication is an implicit indication based at least in part on a first symbol of a first demodulation reference signal (DMRS) and a second symbol of a second DMRS.
10 . The UE of claim 9 , wherein the first symbol is a starting symbol of the first set of symbols and the second symbol is a starting symbol of the second set of symbols.
11 . The UE of claim 8 , wherein downlink control information indicates at least one of the first spatial parameter, the second spatial parameter, or the first set of symbols and the second set of symbols in which the single communication is scheduled.
12 . The UE of claim 8 , wherein the first set of symbols and the second set of symbols are contiguous.

respective first and second quasi co-location parameters,
respective first and second transmission configuration indicator (TCI) states,
respective first and second precoding parameters,
respective first and second spatial domain filters, or
a combination thereof.
14 . The UE of claim 8 , wherein the first spatial parameter is different than the second spatial parameter.
15 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
receive an indication of a first set of symbols and a second set of symbols in which a single communication is scheduled, wherein the single communication does not include multiple repetitions of a transport block; and
transmit or receiving the single communication in the first set of symbols and the second set of symbols using a first spatial parameter for the first set of symbols and a second spatial parameter for the second set of symbols.
16 . The non-transitory computer-readable medium of claim 15 , wherein the indication is an implicit indication based at least in part on a first symbol of a first demodulation reference signal (DMRS) and a second symbol of a second DMRS.
