Abstract :
Device-to-Device (D2D) underlaying cellular network is considered to be a promising resource reuse technique. While many literatures have been investigating the air-interface performance of D2D in cellular networks from the physical and/or media access control (MAC) layers, we in this paper introduce factors about contents of information streams (upper layer factors) into the system model and conduct a cross-layer study. To better model the upper layer factors, a new concept called information correlation is proposed and formulated, which can be used as a reference to measure the importance of contents for potential D2D users when we design particular schemes. The proposed model quantitatively estimates users´ service demands from the contents perspective to further differentiate user resource allocation, for improving the system performance more effectively with better user experience. A test model and several application examples for information correlation are provided, with simulation carried out for a LTE-based scenario, which corroborates a significant performance gain over traditional schemes.
