Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a plurality of resource blocks of a short channel mapped using a short resource element group (sREG) to short control channel element (sCCE) mapping. The short channel may be a short physical downlink control channel (sPDCCH) or a short physical downlink shared channel (sPDSCH). The wireless communication device may process the short channel using the plurality of resource blocks. The plurality of resource blocks may be bundled into a set of resource block bundles based at least in part on the sREG-to-sCCE mapping.
