Abstract
The present invention discloses a method of allocating downlink traffic channel resources for multi-carrier HSDPA, and the method includes: first of all, selecting a carrier with the optimum channel condition; determining whether the carrier meets the resource allocation demand of a downlink traffic channel, if yes, allocating resources that meet the downlink traffic channel on the carrier; otherwise, allocating the available resources of the carrier to the downlink traffic channel, and selecting a carrier with the optimum channel condition from the remaining carriers for resource allocation according to the remaining resource allocation demand of the downlink traffic channel. The present invention provides, according to the transmission characteristic of the existing HSDPA multi-carrier, a method for allocating downlink traffic channel resources, which method is applicable for packet data transmission of the multi-carrier HSDPA.
