APPARATUS AND METHOD FOR RECEPTION AND TRANSMISSION OF CONTROL CHANNELS IN LISTEN-BEFORE-TALK WIRELESS SYSTEM

摘要

A method and system of creating, transmitting, receiving and interpreting a subframe structure used in the communication between a base station and a device with mobile communication functionality is provided for use during communication on an unlicensed frequency spectrum. The system and subframe structure provides for the truncation of OFDM symbols within one or more subframe structures that often contain downlink control information and a method for determining a new location of the truncated downlink control information within the subframe structure.
