Techniques pertaining to subband full duplex (SBFD) user equipment (UE) reporting hard constraints on full-duplex scheduling to network nodes are described. Such techniques include establishing full-duplex communication between a UE and a network node such that the UE is able to transmit data to the network node and receive data from the network node simultaneously in time. The techniques further include reporting by the UE to the network node one or more hard constraints on a full-duplex scheduling of communication resources that is performed by the network node for the UE during the full-duplex communication.
