Abstract

Описаны технологии для поддержания произвольного доступа с помощью абонентских устройств (UE) в системе беспроводной связи. В одной схеме, UE передает преамбулу произвольного доступа (RA) для произвольного доступа. UE после этого принимает ответ по произвольному доступу, который состоит из первой части и второй части. Первая часть включает в себя список из N идентификаторов преамбул RA для N преамбул RA, на которые отвечают с помощью ответа по произвольному доступу, где N(1. Вторая часть включает в себя N отдельных ответов по RA для N преамбул RA, на которые отвечают. UE обрабатывает первую часть, чтобы обнаруживать идентификатор преамбулы RA для преамбулы RA, которая передается с помощью UE. Если этот идентификатор преамбулы RA не обнаружен, то UE пропускает вторую часть. Иначе, UE обрабатывает вторую часть, чтобы получать отдельный ответ по RA для преамбулы RA, которая передается.
