1. A method for wireless communications at a first wireless device, comprising:
receiving, via a sidelink channel, control information comprising a parameter associated with a first frequency domain resource allocation of a first transport block associated with an initial transmission and an indication of a second frequency domain resource allocation of a second transport block associated with a subsequent transmission after the initial transmission, wherein the parameter comprises a scaling factor indicating that a size of the first frequency domain resource allocation is different than a size of the second frequency domain resource allocation;
identifying the first frequency domain resource allocation of the first transport block based at least in part on receiving the control information that includes the parameter and the indication;
communicating, with a second wireless device via the sidelink channel, one or more signals based at least in part on identifying the first frequency domain resource allocation of the first transport block and receiving the indication of the second frequency domain resource allocation of the second transport block; and
transmitting, to the second wireless device via the sidelink channel, a request to retransmit a portion of the first transport block, the second transport block comprising the portion of the first transport block based at least in part on the request, and the request comprising an indication of an amount of frequency domain resources for the second transport block.
