Abstract
A code is produce for use in scrambling or descrambling data associated with a high speed shared control channel (HS-SSCH) for a particular user equipment. A user identification of the particular user equipment comprises L bits. A ½ rate convolutional encoder processes at least the bits of the user identification by a ½ rate convolutional code to produce the code.
Claims10
An apparatus comprising:
- an input configured to accept a user identification comprising L bits;
- and
- an output configured to produce a code used for scrambling a high speed shared control channel (HS-SCCH);
- wherein the apparatus effectively processes at least the L bits of the user identification by a ½ rate convolutional code.
1 more element
A user equipment comprising:
- an input configured to accept a 16 bit user identification;
- and
- a device for processing the 16 bit user identification code with eight appended zero bits effectively using a ½ rate convolutional encoding to produce a 48 bit code for use in descrambling a high speed shared control channel (HS-SCCH).
A user equipment comprising:
- an input configured to accept a 16 bit user identification;
- and
- means for processing the 16 bit user identification code with eight appended zero bits effectively using a ½ rate convolutional encoding to produce a 48 bit code for use in descrambling a high speed shared control channel (HS-SCCH).
A base station comprising:
- an input configured to accept a 16 bit user identification;
- and
- a device for processing the 16 bit user identification code with eight appended zero bits by effectively performing a 1/2 rate convolutional encoding to produce a 48 bit code for use in scrambling a high speed shared control channel (HS-SCCH) for a user equipment associated with the 16 bit user identification.
