Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may determine a grid allocation of single carrier resource blocks (SC-RBs) that defines a plurality of SC-RBs in a time domain and in a frequency domain. The first node may perform, to a second node, a frequency division multiplexed transmission associated with a single carrier waveform using one or more SC-RBs indicated in the grid allocation of SC-RBs. Numerous other aspects are described.
