Abstract
Lately several Single Frequency Dual Cell (SF-DC) techniques for High Speed Downlink Packet Access (HSDPA) were considered in the Third Generation Partnership Project (3GPP), which were aimed to enhance network performance for users at the cell edges. In this paper we are concentrating on intra-site multiflow aggregation scheme, where User Equipment (UE) can receive two independent transmissions from separate sectors. Furthermore, this paper focuses on the impact of Channel Quality Indicator (CQI) reporting interval and measurement imperfections on the system performance. Moreover, we present a joint scheduling algorithm, which selects users site-wide instead of independently in each sector. Simulation results for scenarios mentioned above are presented and analysed in the paper. This study shows that joint scheduling gives some extra gain compared to independent scheduling. In addition, impact of CQI errors and CQI update period are studied.
