APPARATUS AND METHOD FOR CONFIGURING CONTROL CHANNELS FOR NARROWBAND USER EQUIPMENT

摘要

The present invention relates to configure control channels for narrowband user equipment. A base station for sending a control channel in a wireless communication system includes a control information generation unit configured to generate a first CFI to be mapped to a first PCFICH and a second CFI to be mapped to a second PCFICH, a channel mapper configured to map the first CFI to the first PCFICH and map the second CFI to the second PCFICH, a transmission unit configured to map the first PCFICH and the second PCFICH to one or more predefined PRBs on one or more predefined OFDM symbols in a central band on a system operating frequency and transmit the one or more PRBs to user equipment, wherein the first CFI indicates first 4 or smaller OFDM symbols within a subframe and the second CFI indicate indices of the one or more predefined PRBs.
