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

摘要

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