SCHEDULING OF AN UPLINK TRANSMISSION OF MULTIPLE TRANSPORT BLOCKS
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes an uplink grant indicating information relating to multiple transport blocks for an uplink transmission, the information indicating which of the multiple transport blocks is to be transmitted. The UE may transmit one or more of the multiple transport blocks in accordance with the DCI. Numerous other aspects are described.
1 . A user equipment (UE) for wireless communication, comprising:
one or more antennas; and
a processing system that includes one or more processors and one or more memories that store code and are coupled with the one or more processors, the processing system configured to cause the UE to:
receive first downlink control information (DCI) that includes a first uplink grant for an uplink transmission of multiple transport blocks;
transmit the uplink transmission of the multiple transport blocks;
receive second DCI that includes a second uplink grant for retransmission of a transport block of the multiple transport blocks,
wherein the second DCI is associated with a hybrid automatic repeat request (HARQ) process identifier for the transport block to be retransmitted; and
transmit the retransmission of the transport block.
2 . The UE of claim 1 , wherein the uplink transmission of the multiple transport blocks is a physical uplink shared channel (PUSCH) transmission.
3 . The UE of claim 1 , wherein the uplink transmission of the multiple transport blocks is an initial transmission of the multiple transport blocks.
4 . The UE of claim 1 , wherein the uplink transmission of the multiple transport blocks is on eight transmission layers.
5 . The UE of claim 1 , wherein the first uplink grant indicates the HARQ process identifier.
6 . The UE of claim 1 , wherein the multiple transport blocks are associated with the HARQ process identifier.
7 . The UE of claim 1 , wherein the processing system, to transmit the retransmission of the transport block, is configured to cause the UE to:
transmit the retransmission of the transport block on four transmission layers.
8 . A network node for wireless communication, comprising:
one or more antennas; and
a processing system that includes one or more processors and one or more memories that store code and are coupled with the one or more processors, the processing system configured to cause the network node to:
transmit first downlink control information (DCI) that includes a first uplink grant for an uplink transmission of multiple transport blocks;
receive the uplink transmission of the multiple transport blocks;
transmit second DCI that includes a second uplink grant for retransmission of a transport block of the multiple transport blocks,
wherein the second DCI is associated with a hybrid automatic repeat request (HARQ) process identifier for the transport block to be retransmitted; and
receive the retransmission of the transport block.
9 . The network node of claim 8 , wherein the uplink transmission of the multiple transport blocks is a physical uplink shared channel (PUSCH) transmission.
10 . The network node of claim 8 , wherein the uplink transmission of the multiple transport blocks is an initial transmission of the multiple transport blocks.
11 . The network node of claim 8 , wherein the uplink transmission of the multiple transport blocks is on eight transmission layers.

13 . The network node of claim 8 , wherein the multiple transport blocks are associated with the HARQ process identifier.
14 . The network node of claim 8 , wherein the processing system, to receive the retransmission of the transport block, is configured to cause the network node to:
receive the retransmission of the transport block on four transmission layers.
15 . A method of wireless communication performed by a user equipment (UE), comprising:
receiving first downlink control information (DCI) that includes a first uplink grant for an uplink transmission of multiple transport blocks;
transmitting the uplink transmission of the multiple transport blocks;
receiving second DCI that includes a second uplink grant for retransmission of a transport block of the multiple transport blocks,
wherein the second DCI is associated with a hybrid automatic repeat request (HARQ) process identifier for the transport block to be retransmitted; and
transmitting the retransmission of the transport block.
16 . The method of claim 15 , wherein the uplink transmission of the multiple transport blocks is a physical uplink shared channel (PUSCH) transmission.
