Stealing From an Ongoing Flow

 

Abstract:

Overlay services, where new devices may be allowed to use the same spectrum as the existing devices, are being considered as a possible method to increase operational efficiency of allocated spectrum.  In this talk, we discuss a basic scenario of one secondary flow (in overlaid services) trying to maximize its transmission rate in the presence of an ongoing flow. We will discuss two variants of the interference channel and our first set of results, highlighting the importance of power control and feedback in such systems.
