The high-speed downlink packet access (HSDPA) system can effectively support real-time voice services if the HS-SCCH-less feature is adopted in the 3GPP Release 7 standard. In this paper, we point out that the feature only offers a limited statistical multiplexing capability and it also causes serious power consumption at the user equipment. This paper proposes an HSDPA scheduling operation that utilizes the entire code space and considers the packet generation pattern of voice services.
