Abstract: Provided are a method and an apparatus for transmitting uplink control information (UCI), which is carried out by a terminal in a wireless communication system. If the number of information bits of the UCI falls inside a specific range when different types of UCI are transmitted through the same PUCCH format, a bit sequence of each of the UCI are channel-coded by aligning/interleaving, wherein the aligning/interleaving is carried out so that the UCI having high importance are channel-coded so as to have better decoding performance.

Abstract: Provided are a method and apparatus for transmitting acknowledgement/not-acknowledgement (ACK/NACK) of a user equipment in a carrier aggregation system. The method includes: assigning first and second control regions as search spaces for a specific cell; detecting scheduling information with respect to the specific cell from the first control region and/or second control region; receiving a data channel from the specific cell on the basis of the scheduling information; and transmitting ACK/NACK indicating a reception acknowledgement for the data channel, wherein if the scheduling information is detected from the first control region, the ACK/NACK is transmitted using a radio resource linked to another radio resource used to receive the scheduling information, and wherein if the scheduling information is detected from the second control region, the ACK/NACK is transmitted using a pre-set radio resource through a higher layer signal.

Abstract: Provided is a method of transmitting ACK/NACK in a TDD-based wireless communication system. The method includes: receiving M downlink subframes associated with an uplink subframe n in each of two serving cells; determining four candidate resources based on the M downlink subframes received in each of the two serving cells; and transmitting an ACK/NACK response for the M downlink subframes by using one resource selected from the four candidate resources in the uplink subframe n, wherein the two serving cells includes a first serving cell and a second serving cell, and wherein among the four candidate resources, a first resource and a second resource are associated with a PDSCH or a SPS release PDCCH for releasing semi-persistent scheduling received in the first serving cell, and a third resource and a fourth resources are associated with a PDSCH received in the second serving cell.

Abstract: A method is provided for a User Equipment (UE) operating in a wireless communication system. The method includes monitoring a control channel candidate with a downlink control information (DCI) format size in a plurality of search spaces. Each of the plurality of search spaces corresponds to a respective carrier indicator field (CIF) value. The method further includes transmitting or receiving data using downlink control information which is detected by monitoring the control channel candidate. In a state that control channel candidates have different values of carrier indicator field for the DCI format size, the control channel candidate with the DCI format size is received in any search space corresponding to any of the different values of carrier indicator field for the DCI format size.

Abstract: A method for uplink transmission in a wireless communication system, the method includes determining, by a user equipment (UE), whether the first uplink signal to be transmitted toward a first cell belonging to a first timing advance group (TAG) at an nth subframe overlaps the second uplink signal to be transmitted toward a second cell belonging to a second TAG at an (n+1)st subframe; dropping, by the UE, the first uplink signal at the nth subframe, if a total transmission power including the first and second uplink signals exceeds a maximum transmit power, where n is an integer≥1; and transmitting the second uplink signal without the first uplink signal which is dropped.

Abstract: Provided is a method and an apparatus for transmitting uplink control information by a terminal in wireless communication system. When a PUCCH resource used for transmitting only periodic CSI from a subframe, the resource is a first resource, and a resource indicated by ARI is a second resource, when a setting allows transmitting togetherACK/NACK and the periodic CSI through a PUCCH from the same subframe, the first resource and the second resource are mutually exclusive, and the second resource that is used for transmitting together the ACK/NACK and the periodic CSI uses the resource indicated by the ARI from resources determined by an RRC.

Abstract: A method and low-cost/low-capability (LC) device are provided for performing a random access procedure in a wireless communication system. The LC device receives configuration information for a random access procedure from a base station. The configuration information includes resource information for transmitting a random access preamble, and the resource information is specific to the LC device. The LC device transmits, to a base station, a random access preamble on a random access resource determined based on the resource information. The LC device receives a random access response in response to the random access preamble. The random access resource is configured for each region of a coverage of the base station.
