Abstract

Рассматриваются технологии для поддержания связи в неоднородной сети. В одном аспекте, связь в сценарии доминирующих помех может поддерживаться за счет резервирования субкадров для слабой базовой станции, подвергающейся воздействию интенсивных помех от базовой станции с интенсивными помехами. В другом аспекте, помехи при помощи первого опорного сигнала от первой станции (например, базовой станции) могут быть смягчены с помощью устранения помех на второй станции (например, пользовательского оборудовании (UE)) или с помощью выбора других ресурсов для передачи второго опорного сигнала второй станцией (наприме�
