2014 IEEE International Symposium on Dynamic Spectrum Access Networks (DYSPAN) 2014 # Resource allocation with carrier aggregation in LTE Advanced cellular system sharing spectrum with S-band radar

**Abstract:** Spectrum sharing is a promising solution for the problem of spectrum congestion. We consider a spectrum sharing scenario between a multiple-input multiple-output (MIMO) radar and Long Term Evolution (LTE) Advanced cellular system. In this paper, we consider resource allocation optimization problem with carrier aggregation. The LTE Advanced system has N BS base stations (BS) which it operates in the radar band on a sharing basis. Our objective is to allocate resources from the LTE Advanced carrier and the MIMO …

“…It represents the beampattern of a moving maritime MIMO radar. Since interference channels are evolving fast, beampattern is obtained by solving the optimization problem in equation (15) and then projecting the resulting waveform onto the null space ofH using the projection matrix in equation (10). The resulting waveform covariance matrix is given by…”

“…The rate allocation problem is formulated as two convex optimization problems, where the radar-interfering sector assignments are extracted from the portion of the spectrum non-overlapping with the radar operating frequency. Another resource allocation algorithm with carrier aggregation is proposed in [175] to facilitate coexistence of LTE Advanced cellular systems and S-band radar systems. In particular, the proposed algorithm gives priority to users with inelastic traffic.…”
