ABSTRACT The paper compares two hybrid automatic repeat request (HARQ) schemes using incremental redundancy (IR) which have been proposed for the UMTS (W-CDMA) high speed downlink shared channel (HS-DSCH). Their relative throughput performance is reported for various channel conditions. It is shown that the two-stage rate-matching scheme has marginally worse performance compared to the alternative block interleaving scheme for certain coding rates and under some channel conditions.

    ABSTRACT: HSDPA-based UMTS networks should offer high bit rate connections in the next generation wireless networks. However, radio resources available to achieve them are limited. This paper presents suggestions to optimize some HSDPA techniques such as scheduling in single and multi-service cases while distinguishing terminal capabilities.

    ABSTRACT: In this paper, the Medium Access Control (MAC) proto-col for the High Speed Downlink Packet Access (HSDPA) of the Wideband CDMA (WCDMA) radio transmission is studied. In a packet radio network, the delay performance is of special interest. HSDPA is a new concept, which en-hances downlink performance of the WCDMA air inter-face to lower packet delays and higher throughput. The HSDPA MAC protocol is shortly introduced and its impact to the buffering requirements is studied. The retransmis-sion probability and Transport Format selection probabil-ity are presented as distributions. Finally, the performance results are analysed from the simulated measures of packet delay distributions and window occupancy distributions.

    ABSTRACT: High speed downlink packet access (HSDPA) technology was standardized for 3GPP W-CDMA release-5. HSDPA includes advanced techniques such as adaptive modulation and coding (AMC), hybrid ARQ (HARQ), and fast scheduling. HSDPA can deliver a 3× increase in sector and a 6× increase in user throughput for some traffic models. Additionally HSDPA can support almost a 4× increase in the number of users compared to UMTS release-99 for the same service. With advanced receivers, HSDPA can support broadband quality service with 60 users per site. This paper provides an overview of the physical layer aspects of HSDPA and discusses the improvements in sector and user throughput (with respect to release-99 UMTS) resulting from HSDPA with joint scheduling and resource allocation.
