Patent ID: 8004959

Claim:
A user equipment unit for use in a code division multiple access (CDMA) network, comprising: a transceiver configured to perform radio communications with a radio access network; a memory configured to store plural orthogonal codesets; a code selector configured to select a code from one of the plural codesets for use in performing the radio communications with the radio access network; wherein the plural orthogonal codesets have at least a first code in common with one another, wherein the plural orthogonal codesets is generated by a process comprising: (1) forming a set of simplex codesets, each simplex codeset of the set being configured using a different maximum length sequence, (2) extending each simplex codeset of the set to obtain an extended orthogonal codeset, (3) using at least some extended orthogonal codesets for inclusion as one of the plural orthogonal codesets, and (4) including a Walsh Hadamard codeset as one of the plural orthogonal codesets.
