Abstract:
1. A method of allocating code resources for a high speed physical downlink shared channel, HS-PDSCH, in a system comprising a radio network controller and a base station, the method comprising: recording, and updating usage states of code resources at the base station, wherein the base station determines the usage states of the code resources according to messages from the radio network controller, and when the base station receives a message from the radio network controller indicating that a code in the code resources having same spreading factors as channelization codes of the HS-PDSCH is allocated, the base station marks the usage state of the code as occupied, and if a subcode of the code is allocated by the radio network controller, the base station marks the usage state of the code to which the subcode corresponds as occupied; and allocating at the base station code with idle state to the HS-PDSCH when the code resources of the HS-PDSCH are not enough.
