Netw ork Overview
HSDPA
(
High Speed Downlink Packet Access)
HSDPA is based on WCDMA and is standardized as part of 3GPP Release 5 WCDMA
specifications. The new modulation method improves system capacity and increases user data
rates in the downlink direction. Key performance improvements are:
specifications. The new modulation method improves system capacity and increases user data
rates in the downlink direction. Key performance improvements are:
• Adaptive modulation and coding
• Fast packet scheduling function as controlled by the Node B (base station or BTS), rather
• Fast packet scheduling function as controlled by the Node B (base station or BTS), rather
than by the radio network controller (RNC).
• Fast retransmissions (HARQ-Hybrid Automatic Repeat Request) with incremental
redundancy
The WCDMA system normally carries user data over dedicated transport channels, or DCHs.
HSDPA introduces a new transport channel type, High Speed Downlink Shared Channel (HS-
DSCH) that makes efficient use of radio frequency resources and accounts for bursty packet
data. The High Speed Downlink Shared Channel (HS-DSCH) shares multiple access codes,
transmission power and also shares infrastructure hardware between several users. The radio
network resources can efficiently serve a large number of users who are accessing bursty data.
