    Abstract: A connection establishment method for a Machine Type Communication (MTC) User Equipment (UE) in a wireless communication system is provided. A MTC UE receives system information from at least one neighbor Base Station (BS). The system information includes information regarding whether or not the at least one BS supports MTC UE. The MTC UE determines at least one candidate BS based on the system information. The at least one candidate BS supports the MTC UE. The MTC UE determines a last BS based on an intensity of a signal from the at least one candidate BS. The MTC UE sends a random access preamble to the last BS.

    Abstract: Provided are a communication method for a cooperative multi-point and a wireless device using the same. The wireless device receives, from a first cooperative multi-point (CoMP) cell, a first physical downlink shared channel (PDSCH) in a first subframe of a first frequency band, and receives, from a second CoMP cell, a second PDSCH in a second subframe of a second frequency band. A portion or the entire first frequency band is overlapped with the second frequency band. A first start point at which the first PDSCH in said first subframe starts being scheduled is the same as a second start point at which the second PDSCH in said second subframe starts being scheduled.

    Abstract: A method and a user equipment (UE) for transmitting control information in a wireless communication system are discussed. The method according to one embodiment includes receiving a parameter which indicates whether transmission of a hybrid automatic repeat request acknowledgement (HARQ-ACK) on a physical uplink control channel (PUCCH) and a sounding reference signal (SRS) in one subframe is configured; if the parameter is true, transmitting, in a primary component carrier (CC), the PUCCH, which coincides in a same subframe as the SRS, by using a shortened PUCCH format carrying at least one of the HARQ-ACK and a positive scheduling request (SR); and if the parameter is false, transmitting the PUCCH by using a normal PUCCH format, while not transmitting, in a secondary CC, the SRS which coincides in the same subframe as the PUCCH. The shortened PUCCH format is a shortened PUCCH format 1/1a/1b or a shortened PUCCH format 3.
