SOFTWARE DEFINED RADIO

A method for providing a division of SDR RA into operational states is described. The method includes, in a device which including a plurality of shared device resources and a plurality of RAs, receiving, from a first RA, a request to change a state of the first RA to a requested active state. The requested active state is one of a plurality of potential active states for the first RA and each potential active state has an associated set of device resource requirements. The method also includes determining whether sufficient device resources exist for the requested active state based at least in part on currently allocated device resources. In response to a determination that sufficient device resources exist, the change to the requested active state for the first RA is approved. Apparatus and computer readable media are also described.
