Abstract

1. Способ беспроводной связи в терминале беспроводной связи, который осуществляет связь с беспроводной базовой станцией с использованием мультиплексирования с ортогональным частотным разделением (OFDM), причем способ содержит этапы, на которых:принимают от базовой станции выделение радиоресурсов по каналу управления в радиокадре,причем упомянутый радиокадр содержит, по меньшей мере, первый подкадр и второй подкадр, следующий за первым подкадром, и каждый из подкадров содержит множество OFDM символов,причем выделение радиоресурсов выделяет ресурсы для одного или более подкадров, ипричем канал управления включает в себя множество полей выделения ресурсов, иопределяют в терминале беспроводной связи, что выделение ресурсов предназначено либо для блока ресурсов в обоих из первого и второго подкадров, либо для блока ресурсов только во втором подкадре.2. Способ по п.1, в котором при упомянутом определении определяют в терминале беспроводной связи, что выделение ресурсов предназначено для одного и того же блока ресурсов в обоих из первого и второго подкадров.
