1. A method for wireless communications by a first user equipment (UE), comprising:
receiving, by the first UE, a first indication of a configuration of a sidelink resource pool for a group of UEs that includes the first UE, wherein the sidelink resource pool comprises one or more slots in a time domain and one or more subchannels in a frequency domain, and wherein a slot of the sidelink resource pool comprises a control region allocated for a sidelink control channel and a set of contiguous subslots each allocated for a sidelink data channel;
receiving, by the first UE, a second indication for the sidelink resource pool of a subslot pattern for the slot of the sidelink resource pool, the subslot pattern indicating a quantity of subslots within the slot and a length of each subslot of the quantity of subslots;
transmitting, by the first UE to a second UE of the group of UEs in the control region of the slot, sidelink control information that reserves a subslot from the subslot pattern for the slot for a transmission of a sidelink message to the second UE; and
transmitting, by the first UE, at least a portion of the sidelink message to the second UE in the subslot.
