By upgrading existing WCDMA networks with HSPA (High Speed Packet Access) the maximum data rates DL and UL can be dramatically increased, and thereby also bitrate demanding services can be supported. The main changes required when introducing HSPA relates to the MAC and PHY layer.
This course starts with introducing HSDPA and HSUPA in the context of WCDMA. Then HSDPA specific features are presented with focus on changes introduced in the MAC and PHY layers. MAC-hs is a new protocol introduced.
It is located in Node B and has responsibility for scheduling, fast link adaptation and Hybrid-ARQ (HARQ). The physical layer is involved in HARQ and handles new types of modulation and transport formats. The new transport and physical channels are also introduced. A traffic case in which a user is allocated HSDPA resources is presented. Calculations of HSDPA data rates are also described. Continuing with HSUPA, also known as enhanced UL, the focus is still on MAC and PHY. In HSUPA two new MAC protocols are introduced, MAC-e in Node B with responsibility for scheduling and HARQ, and MAC-es in RNC with responsibility for UL packet reordering. Also for HSUPA the PHY layer handles new types of modulation and transport formats, a number of new physical channels are introduced as well as one new transport channel. Also for HSUPA an example of data rate calculation is presented. Finally the processes involved when a UE with both HSDPA and HSUP services active changes serving cell is presented. |
