The below patent is from the same family as the patents in dispute in the Nokia ITC investigation. Remember the whole discussion we had on this board about scrambling and descrambling. Apparently IDCC is being consistent and indicating that scrambling means both scrambling and decrambling.

User equipment identification specific scrambling


Abstract
A base station for use in a code division multiple access communication system comprises circuitry configured to process a user equipment identification (UE ID) by 1/2 rate convolutionally encoding the UE ID to produce a code. The code is used by the base station for scrambling a high speed shared control channel (HS-SCCH). The base station is configured to transmit a wireless signal. The wireless signal provides the user equipment with payload data carried on a high speed physical downlink shared channel (HS-PDSCH). The HS-PDSCH is associated with the HS-SCCH.
