HSDPA
3GPP has recently started activities on joint scheduling across two HSDPA carriers to increase the peak data rates per user and better utilize the available resources by multiplexing carriers in CELL DCH state. This dual carrier approach called DC-HSDPA offers both higher resource utilization efficiency and frequency selectivity in order to achieve better performance gains particularly for UEs in unfavourable channel conditions. This paper gives an overview of the related study and work items on dual carrier operations. We discuss the changes required to support the flexible operation of dual carrier and highlight the expected gains. Furthermore, some preliminary technological proposals for future evolution of Multi-Carrier HSPA are introduced and briefly evaluated. Nomor Research has been involved in 3GPP standardisation, simulation and demonstrations since the establishment of the work item and offers related services.
