Abstract:
1. A method of allocating Walsh codes and Quasi-orthogonal Functional, QoF, codes to mobile terminals in a Code Division Multiple Access, CDMA, system in which a finite number of Walsh codes are defined, and some mobile terminals operating in the CDMA system are capable of supporting Advance Quasi-Linear Interference Cancellation, AQLIC, and some mobile terminals operating in the CDMA system are non-AQLIC-capable, the method comprising the steps of: determining a user loading per carrier-sector; determining whether the finite number of Walsh codes is sufficient to support the user loading; when the finite number of Walsh codes is sufficient to support the user loading, allocating Walsh codes to both the AQLIC-capable mobile terminals and the non-AQLIC-capable mobile terminals; and when the finite number of Walsh codes is not sufficient to support he user loading:
