Repurposed fields may be arranged according to radio resource control (RRC) configuration information, a most significant bit (MSB), a least significant bit (LSB), and/or one or more bits being directed to specific SCell dormancy with one or more other bits being directed to SCell group dormancy, subsets of SCells, and/or a pre-defined rule. These and many other features and examples are described herein.
