<p>High Speed Uplink Packet Access method and system used in Multi-carrier TD-SCDMA system are disclosed. The method includes the following steps. Carrier resources bearing scheduled Enhanced Physical Uplink Channel are allocated to user equipment. Enhanced Absolute Grant Channel and Enhanced HARQ Acknowledgement Indicator Channel are set among the allocated carrier resources. Enhanced Dedicated Channel transmitting data are mapped to Enhanced Dedicated Channel, and further are mapped to scheduled Enhanced Physical Uplink Channel, through the Media Access Layer. Through Enhanced Absolute Grant Channel, scheduled Enhanced Physical Uplink Channelis scheduled and granted to the user equipment to transmit Enhanced Dedicated Channel transmitting data to the base station. The state information reflecting the reception of Enhanced Dedicated Channel transmitting data at the base station is fed to the user equipment through Enhanced HARQ Acknowledgement Indicator Channel. The carrier resources in Multi-carrier TD-SCDMA system are utilized efficiently and thus the uplink throughput in the cell is improved.</p> |
