Expand The Voice Evolution—VoLTE. VoHSPA+, WCDMA+ and Quality
The wireless industry is moving toward a richer, packet based voice on IP. However, traditional mobile Circuit Switched (CS) voice has a long life during the transition to carrier grade VoIP.

Expand Benefits of HSPA Supplemental Downlink
Supplemental Downlink (SDL) has been enabled in Release 9 as part of the evolution of High Speed Downlink Packet Access (HSDPA). While the serving carrier (cell) for an HSDPA UE is part of paired spectrum, the SDL carrier is part of unpaired spectrum in a different band. Thus, SDL operation helps efficiently utilize unpaired spectrum for HSDPA.

Expand Performance Gains of Single-Frequency Dual-Cell HSDPA

In this paper, we study the scheme of Single-Frequency Dual-Cell HSDPA (SF-DC HSDPA) which is introduced to simultaneously transmit two separate packet streams from two cells to a mobile. The inter-stream interference is suppressed by the linear-MMSE equalizer at the mobile.
