摘要: We consider the K-user Gaussian interference channel in context of downlink a cellular system where base stations can exchange messages through backhaul network, and interfering users be jointly served by multiple stations. To limit load on number (base station) transmitters sharing given message is bounded M, which we call cooperation order. provide outer bounds sum degrees freedom this system, are shown to tight special cases.
