Transmission batch scheduling and resource management
Methods, systems, and devices for wireless communications are described. Devices of a wireless communications system may be configured to group data packets as a batch or file. In some cases, resources may be determined based on one or more resource grants corresponding to file communication. Other aspects may include DCI configurations corresponding to file communication, resource grants may be configured to assign resources for communication of a file. For example, a DCI may be specifically configured for granting resources for communication of a file. In another example, configured grants may include a configured grant index corresponding to communication of a file. Other aspects may include configuration of a UE for responding to a preemption indication when a file is scheduled for communication, power adjustments for communication of a file, reference signal configurations for communication of a file, and/or coherent detection/transmission across two or more packets of a file.

9 . The method of claim 8 , wherein the batch of transmissions is transmitted to the network entity, and wherein applying the preemption indication to the processing or the transmission of the batch of transmissions comprises:
transmitting a first portion of the file using resources of the first resources that precede the portion of the first resources indicated as preempted; and
refraining from transmitting a second portion of the file on the portion of the first resources indicated as preempted, in accordance with the rule for preemption of batches.
10 . The method of claim 7 , wherein the batch of transmissions is received from a network entity, and wherein applying the preemption indication to processing or transmission of the batch of transmissions comprises:
processing the batch of transmissions or transmitting the file by ignoring the preemption indication, in accordance with the rule for preemption of batches.
