1. A method of wireless communication at a relay device, comprising:receiving, from a serving station, a serving station physical downlink control channel (PDCCH) that comprises control information comprising data slot partition information indicating data slots partitioned for communication between the serving station and the relay device and for communication between the relay device and an end device, wherein the data slot partition information comprises gap out information indicative of one or more of the data slots being available for communication between the end device and the relay device and during which the serving station refrains from transmission;
determining, by the relay device, resource assignment information for the end device based at least in part on the data slot partition information and gap out information received from the serving station;
synchronizing with the end device based at least in part on the control information received from the serving station;
transmitting, by the relay device, a relay PDCCH that comprises the resource assignment information determined by the relay device, the resource assignment information including one or more of the data slots indicated by the gap out information;
receiving a data packet from the end device subsequent to the synchronizing, the receiving based at least in part on the determined resource assignment information; and
transmitting, to the serving station, the data packet received from the end device, the transmitting based at least in part on the control information received from the serving station.
