1. A method for wireless communication by a user equipment (UE), comprising:
receiving downlink control information (DCI) scheduling uplink resources, wherein the uplink resources are scheduled on a secondary cell (SCell) configured on a first spectrum, the scheduled uplink resources to be used for transmitting uplink feedback for at least one downlink transmission relating to at least one of a primary cell (PCell) or another Scell configured on a second spectrum, wherein the DCI schedules the uplink resources on a physical uplink shared channel (PUSCH), wherein the PUSCH is on the SCell, the uplink resources being scheduled on the PUSCH of the first spectrum and not on a physical uplink control channel (PUCCH) on the first spectrum based on the PUCCH being configured as supplemental uplink (SUL) on the first spectrum; and
transmitting the uplink feedback using the scheduled uplink resources in the first spectrum.
