Abstract

Выбор канала с помощью UE в нелицензированных полосах частот. Базовая станция может обмениваться данными с UE с использованием форм несущего LTE/LTE-A-сигнала (например, сконфигурированных в качестве вторичной соты) в нелицензированной полосе частот. Базовая станция может конфигурировать UE для обратной связи по широкополосным помехам для каналов в нелицензированной полосе частот. Измерения интенсивности широкополосного сигнала могут выполняться посредством UE в каналах, в которых базовая станция не передает в данный момент, или в течение периодов молчания сконфигурированной вторичной соты. UE могут передавать в качестве обратной связи среднюю полную принимаемую мощность по полосе пропускания для измерений для одного или более частотных каналов нелицензированной полосы частот. Базовая станция может принимать обратную связь по интенсивности широкополосного сигнала из UE и идентифицировать потенциальные частотные каналы для выбора канала для вторичной соты на основе собственных измерений возможных вариантов каналов и обратной связи по интенсивности широкополосного сигнала из UE.
