Abstract

Запропоновані способи калібрування і формування діаграми спрямованості в системі радіозв'язку. Відповідно до одного з аспектів Вузол В може періодично виконувати калібрування в кожному калібрувальному інтервалі з групою одиниць апаратури UE з метою отримання калібрувального вектора для Вузла В. Вузол В може використовувати цей калібрувальний вектор, щоб врахувати розузгодження характеристик передавального і приймального трактів у Вузлі В. Відповідно до іншого аспекта Вузол В може формувати діаграму спрямованості для зв'язку з апаратурою UE з урахуванням розбалансу коефіцієнтів посилення між декількома антенами апаратури UE. Вузол В може визначити передкодуючу матрицю для формування діаграми спрямованості з урахуванням розбалансу коефіцієнтів посилення унаслідок (і) різних коефіцієнтів посилення системи автоматичного регулювання посилення (АРП (AGC)) для приймальних трактів апаратури UE, (іі) відмінності коефіцієнтів посилення в підсилювачах потужності (РА) для передавальних трактів апаратури UE, і/або (ііі) відмінності коефіцієнтів посилення цих декількох антен.
