This paper presents a joint study of several intercell interference coordination strategies considering both static and dynamic approaches, and with different adjustments in their basic parameters. A wide evaluation is presented with special emphasis on the efficiency vs. fairness tradeoff. Besides, additional performance metrics have been considered as enablers of a full understanding of the strengths...
Carrier aggregation (CA) has been proposed to aggregate two or more component carriers (CCs) to support a much wider transmission bandwidth for LTE-Advanced systems. With carrier aggregation, it is possible to schedule a user equipment (UE) on multiple component carriers simultaneously. In this paper, we evaluate the performance of uplink CA in LTE-Advanced systems with different CC allocation schemes...
This paper describes the implementation detail of an ultra wideband transmitted reference pulse cluster (TRPC) system. The newly proposed TRPC signaling structure consists of multiple pulses with uniform and compact spacing. It overcomes the major hurdle to practical implementation of conventional transmitted reference (TR) systems, that is, the long wideband delay line requirement. In addition, TRPC...
At present, the 3rd Generation Partnership Project (3GPP) has agreed on using the high interference indicator (HII) for uplink inter-cell interference coordination (ICIC). HII indicates the potential uplink interference to other cells. In traditional HII based ICIC schemes, cells suffering from different inter-cell interference receive the same HII, it therefore causes ICIC to have a low efficiency...
