1. A central unit (CU) for wireless communication, comprising:
a one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
transmit, to a first distributed unit, an indication of a traffic flow configuration associated with a traffic flow on a traffic path that includes the first distributed unit and a second distributed unit, the traffic path sharing a common backhaul access protocol (BAP) path identifier with an alternate traffic path associated with the first distributed unit; and
transmit, to the first distributed unit, energy-saving scheduling information identifying the traffic path and the alternate traffic path, the energy-saving scheduling information indicating one or more periods in which the first distributed unit is to use the traffic flow configuration for the traffic flow on the traffic path, wherein the energy-saving scheduling information includes information identifying a periodicity of an availability of the traffic path or an unavailability of the traffic path; and
communicate with the first distributed unit in accordance with the traffic flow configuration and the energy-saving scheduling information during the one or more periods.
