Abstract: A method for a user equipment to control transmit power of an uplink channel in a wireless communication system is disclosed in the present invention. The method includes the steps of setting a power control parameter to each of a plurality of power control processes, selecting a specific beam from among a plurality of beams, determining a specific power control process corresponding to the selected specific beam from among a plurality of the power control processes, adjusting transmit power of each of a plurality of symbols for the uplink channel according to a power control parameter set to the specific power control process, and transmitting the uplink channel to an eNB according to the adjusted transmit power.

Abstract: A method and apparatus for performing an initial access procedure in a wireless communication system is provided. A low cost user equipment (UE) transmits a list of capabilities to a network, and receives a reject message from the network when at least one of the capabilities is not supported by the network. The list of capabilities may be transmitted during a random access procedure via a random access preamble on a physical random access channel (PRACH) or a lmessage 3 on a physical uplink shared channel (PUSCH). The reject message may be received during the random access procedure a random access response or an acknowledge message for the message 3.
