Abstract

Описані способи передачі пілот-сигналу і даних трафіку. В одному аспекті, термінал може скремблювати свій пілот-сигнал за допомогою послідовності скремблювання, сформованої на основі набору статичних і динамічних параметрів. Статичний(і) параметр(и) має(ють) фіксоване значення для всього сеансу зв'язку для термінала. Динамічний(і) параметр(и) має(ють) змінне значення під час сеансу зв'язку. Термінал може формувати послідовність скремблювання за допомогою хешування набору параметрів, щоб одержувати початкове число, та ініціалізації PN-генератора за допомогою початкового числа. Термінал потім може формувати пілот-сигнал на основі послідовності скремблювання. В іншому аспекті, термінал може використовувати різні послідовності скремблювання для пілот-сигналу і даних трафіку. Перша послідовність скремблювання може бути сформована на основі першого набору параметрів і використана для формування пілот-сигналу. Друга послідовність скремблювання може бути сформована на основі другого набору параметрів і використана для скремблювання даних трафіку.
