Abstract

Aspects of the invention generally relate to wireless communications. In some aspects, a repeater may transmit, via a first interface, information associated with a capability of the repeater to provide broadband signals on a second interface. The repeater may receive, via the first interface, a configuration for transmitting the broadband signal on the second interface, and may transmit the broadband signal on the second interface based at least in part on the configuration. Numerous other aspects are provided.
