View Patent ↗Techniques for operating a wireless network in a plurality of radio operating environments are disclosed. In some embodiments, an apparatus receives a first parameter value set that is selected from a group of multiple parameter value sets, wherein the first parameter value set is appropriate for a first target radio operating environment that corresponds to one or more of: a first level of mobility of user devices or a first range of wireless transmission. In some embodiments, the apparatus is reconfigured to receive wireless broadcast transmissions from a second broadcast transmitter using a second parameter value set that is appropriate for a second target radio operating environment. The first and second broadcast transmitters may be the same or different. The parameter value sets may include a first parameter based upon which the apparatus is configured to determine subcarrier spacing and a second parameter that indicates a cyclic prefix size.
