Patent ID: 8331247

Claim:
A method for code channel allocation in a wireless communication system, comprising: establishing a relation between at least one channel estimation window and a channelization code, wherein the at least one channel estimation window corresponding to the channelization code comprises at least one channel estimation window corresponding to all the spread spectrum code branches of a node in which the channelization code exists; and performing code channel allocation according to the relation established, wherein the process of establishing the relation between at least one channel estimation window and a channelization code comprises establishing the relation between the at least one channel estimation window and the channelization code when a maximum number of the channel estimation windows K is any even number between 2-16: when the spread factor is 16, establishing a one-to-one relation between K channel estimation windows and K channelization codes first, then extracting at least 1 channel estimation window from the K channel estimation windows to establish a relation with the remaining 16-K channelization codes; and when the spread factor is less than 16, establishing a relation between each channelization code and channel estimation windows of all the sub-spread spectrum code branches of a spread spectrum code branch of a node in which the channelization code exists.
