METHODS FOR PERFORMING MACHINE TYPE COMMUNICATION FOR THE PURPOSE OF COVERAGE ENHANCEMENT, APPARATUSES AND SYSTEMS FOR PERFORMING THE SAME
First Claim
1. A terminal for receiving a downlink communication from a base station, the terminal comprising:
- a transceiver that transmits and receives a radio signal; and
a processor operatively coupled with the transceiver and configured to;
receive system information, control information and data from the base station,wherein a frequency hopping is performed on the system information, the control information and the data,wherein the frequency hopping is performed using a frequency hopping pattern,wherein the frequency hopping is not performed on a Master Information Block (MIB),wherein a granularity for the frequency hopping pattern varies according to a coverage level,wherein, when the granularity for the frequency hopping pattern is set as a common value, the common value varies according to the coverage level, andwherein, when the common value varies according to the coverage level, the common value is received by the terminal via a System Information Block (SIB) message.

Abstract
A method of performing a downlink machine type communication from a base station to a MTC (machine type communication) terminal includes, at the base station, transmitting at least one of a system information—the system information excluding a Master Information Block (MIB)—, a control information and data to the MTC terminal using a system bandwidth having a predetermined size. The base station performs frequency hopping using a frequency hopping pattern in a unit of narrow band on the at least one of the system information—the system information excluding a Master Information Block (MIB)—, the control information and the data to transmit to the MTC terminal, and the narrow band is less than the system bandwidth.
