A user equipment (UE) may determine that it has first feedback data for downlink communications and second feedback data for sidelink communications. The UE may receive from a base station an indication of resources for the feedback and transmit the first feedback data, the second feedback data, or both, in the resources. In some examples, the UE may transmit the first feedback data in a first set of the resources and transmit the second feedback data in a second set of the resources. In some examples, the UE may drop one of the first or second feedback data based on priorities associated with the feedback data. In some examples, the UE may multiplex the first and second feedback data for transmission in the resources. ## Claims ### Claim 1 A method for wireless communication at a user equipment (UE), comprising: receiving, from a network entity, an indication of a set of resources within an uplink control channel that are reserved for providing feedback for communications to the UE;
