METHOD AND APPARATUS FOR INCREASING ORTHOGONAL CODE SPACE IN A CDMA RAN

Title:

METHOD AND APPARATUS FOR INCREASING ORTHOGONAL CODE SPACE IN A CDMA RAN

Document Type and Number:

WIPO Patent Application WO2004075420

Kind Code:

A3

Abstract:

The present embodiments address the need for an apparatus and method that provides additional orthogonal codes without trading off RF capacity. When a system is operating near its RF capacity and running out of available orthogonal codes, one or more channels are allocated using a new radio configuration ( 510 ) that utilizes longer orthogonal codes. This new radio configuration increases the number of available orthogonal codes without sacrificing RF capacity. Instead, it reduces the peak data rate such a channel can provide.
