1. A method of wireless communication by a control node, the method comprising:
determining a first set of measurements associated with at least one set of beam pairs to provide first control information in a bandwidth part (BWP) to a relay device and to communicate at least one of data or second control information for at least one second wireless device to be relayed by the relay device over a wider frequency bandwidth than the BWP, wherein the at least one set of beam pairs includes at least a first transmit beam and a first receive beam to facilitate communication via at least one of a wireless backhaul link between a first wireless device and the relay device, a first relay access link portion between the first wireless device and the relay device, or a second relay access link portion between the relay device and the at least one second wireless device;
configuring at least one subset of beam pairs of the at least one set of beam pairs based on the first set of measurements, measured in part by the control node, associated with the at least one set of beam pairs; and
transmitting information indicating the at least one subset of beam pairs to the relay device.
