METHODS AND APPARATUSES FOR TRANSMITTING UPLINK IN WIRELESS ACCESS SYSTEM SUPPORTING MACHINE-TYPE COMMUNICATION

摘要

The present invention relates to a wireless access system which supports machine-type communication (MTC), and more particularly, to various methods for efficiently transmitting, by an MTC terminal, uplink control information (UCI) and/or user data, and to apparatuses supporting same. A method for transmitting an uplink by an MTC terminal which supports machine-type communication (MTC) in a wireless access system, according to one embodiment of the present invention, may comprise the steps of: determining whether an overlap exists between a plurality of physical uplink control channels (PUCCHs) for transmitting uplink control information (UCI) and a plurality of physical uplink shared channels (PUSCHs) for transmitting user data; multiplexing UCI in at least one subframe on an overlapping PUSCH when the plurality of PUCCHs and the plurality of PUSCHs overlap in the at least one subframe; and transmitting the PUSCH on which the UCI has been multiplexed in the at least one subframe.

1. A method for performing uplink transmission by a Machine Type Communication (MTC) User Equipment (UE) supporting MTC in a wireless access system, the method comprising:
determining whether a plurality of Physical Uplink Control Channels (PUCCHs) for carrying Uplink Control Information (UCI) are overlapped with a plurality of Physical Uplink Shared Channels (PUSCHs) for carrying user data; if the plurality of PUCCHs are overlapped with the plurality of PUSCHs in one or more subframes, multiplexing the UCI with overlapped PUSCHs in the one or more subframes; and transmitting the PUSCHs multiplexed with the UCI in the one or more subframes.
