A high speed uplink packet access method used for a multi-carrier time division synchronization code division multiple access, TD-SCDMA, system, comprising: allocating to a user equipment, UE, a carrier on which a schedulable enhanced physical uplink channel is configured, and configuring on the allocated carrier an enhanced absolute grant channel and an enhanced hybrid automatic repeat request, HARQ, acknowledgement indicator channel; mapping the data from an enhanced dedicated transport, E-DCH, onto the schedulable enhanced physical uplink channel in a media access control layer; and granting the schedulable enhanced physical uplink channel to the user equipment through the enhanced absolute grant channel for receiving the data from the enhanced dedicated transport channel transmitted from the user equipment to the base station, and the base station feeding back the status information about the received data from the enhanced dedicated transport channel to the user equipment through the enhanced HARQ acknowledgement indicator channel; wherein the physical channel resources of the schedulable enhanced physical uplink channel, the enhanced absolute grant channel and the enhanced HARQ acknowledgement indicator channel are configured on each of more than one carriers in a multiple-carrier cell, and different user equipments carry out E-DCH transmission in a scheduled mode on different carriers of the more than one carriers; characterized in that the process of allocating the carrier, on which the schedulable enhanced physical uplink channel is configured, to the UE comprises the following steps: a radio network controller allocates the carrier, on which the schedulable enhanced physical uplink channel is configured, to the user equipment and requests the base station to allocate, to the user equipment, resource used to control the transport of the data from the enhanced dedicated transport channel; and the base station, in response of the request of the radio network controller, configures the enhanced absolute grant channel and the enhanced HARQ acknowledgement indicator channel on said carrier on which the schedulable enhanced physical uplink channel is configured. allocating to a user equipment, UE, a carrier on which a schedulable enhanced physical uplink channel is configured, and configuring on the allocated carrier an enhanced absolute grant channel and an enhanced hybrid automatic repeat request, HARQ, acknowledgement indicator channel; mapping the data from an enhanced dedicated transport, E-DCH, onto the schedulable enhanced physical uplink channel in a media access control layer; and granting the schedulable enhanced physical uplink channel to the user equipment through the enhanced absolute grant channel for receiving the data from the enhanced dedicated transport channel transmitted from the user equipment to the base station, and the base station feeding back the status information about the received data from the enhanced dedicated transport channel to the user equipment through the enhanced HARQ acknowledgement indicator channel; wherein the physical channel resources of the schedulable enhanced physical uplink channel, the enhanced absolute grant channel and the enhanced HARQ acknowledgement indicator channel are configured on each of more than one carriers in a multiple-carrier cell, and different user equipments carry out E-DCH transmission in a scheduled mode on different carriers of the more than one carriers; characterized in that the process of allocating the carrier, on which the schedulable enhanced physical uplink channel is configured, to the UE comprises the following steps: a radio network controller allocates the carrier, on which the schedulable enhanced physical uplink channel is configured, to the user equipment and requests the base station to allocate, to the user equipment, resource used to control the transport of the data from the enhanced dedicated transport channel; and the base station, in response of the request of the radio network controller, configures the enhanced absolute grant channel and the enhanced HARQ acknowledgement indicator channel on said carrier on which the schedulable enhanced physical uplink channel is configured.
