Patent ID: 7801087

Claim:
A method, comprising: determining, at a receiver, which of a plurality of High-Speed Shared Control Channel (HS-SCCH) communication channels was used for transmitting a message to the receiver, at least the determined channel having a corresponding HS-SCCH channel number; determining a High-Speed Physical Downlink Shared Channel (HS-PDSCH) code of a plurality of HS-PDSCH codes for decoding a further message, the determining achieved by mapping the corresponding HS-SCCH channel number to the HS-PDSCH code using a map that maps each of a plurality of HS-SCCH channel numbers to one of the plurality of HS-PDSCH codes, the HS-PDSCH code used for data transmission being determined from a pre-defined mapping from HS-SCCH channel numbers to corresponding HS-PDSCH codes: and decoding the further message using the determined HS-PDSCH code.
