Abstract
The present invention discloses a control channel allocation method, a packet data transmission method and a RNC of a multi-carrier HSDPA (high speed downlink packet access) technology, wherein the allocation method includes: when a UE accesses a network, the network allocating K pairs of uplink and downlink control channels to be monitored by the UE; during a HSDPA service transmission process, the network selecting N pairs from the K pairs of uplink and downlink control channels to transmit control messages, wherein the selected downlink channels are the corresponding uplink channels are on a same carrier; and the network allocating a pair of uplink and downlink associate channels on each carrier where the selected N pairs of uplink and downlink control channels locate, wherein M≧N≧1 and M is a number of carriers used by the network to transmit packet data. The present invention effectively solves the problem that in the traditional single carrier HSDPA, only the transmission control of the single carrier is taken into account and the control requirement in the multi-carrier HSDPA cannot be satisfied.
