While a heterogeneous network increases the system performance in terms of coverage and capacity, if it is deployed without being well planned and without making use of optimized configurations, it could potentially lead to tough requirements on the mobility performance. The system level simulations shows that in typical scenarios the small separated cell deployment (each low power node is deployed...
Several new features are added for the High Speed Packet Access (HSPA) evolution in order to meet the requirements set by the International Mobile Telecommunications Advanced (IMT-A). The main objective of these new features is to increase the average spectral efficiency. One possible technique for improving downlink spectral efficiency would be to introduce support for four branch multiple input...
