Abstract: A method of transmitting uplink control information (UCI) by a user equipment in a wireless communication system, includes the steps of receiving downlink control information (DCI) indicating a transmission time of the UCI through a prescribed frequency band in a first subframe, receiving a downlink data based on the DCI, and transmitting UCI associated with the downlink data in a second subframe based on the indicated transmission time of the UCI. In this case, the prescribed frequency band on which the DCI is transmitted is configured by a plurality of DCCUs (downlink control channel units) for transmitting the DCI, and the UCI may be transmitted on an UCCU (uplink control channel unit) in the second subframe, a frequency band of the first UCCU being same as a frequency band corresponding to a DCCU of a lowest frequency among the plurality of DCCUs.

Abstract: Disclosed herein is a concatenated code encoding method for improving a turbo code. The concatenated code encoding method of the present disclosure includes encoding an input signal based on a repetition-accumulation (RA) code as an outer code, adding a tail bit to the encoded input signal, and encoding the encoded input signal based on the a turbo code. The concatenated code encoding method may further include interleaving the encoded input signal after application of the outer code.

Abstract: A method and corresponding user equipment (UE) for configuring a circular buffer in a wireless communication system. The method includes: generating a code block including a payload, a first outer code parity, and a second outer code parity from an input signal based on an outer code in a higher layer; generating a codeword from the code block based on an inner code in a physical layer; and configuring a circular buffer including the codeword and one or more second outer code parities. The first outer code parity is generated based on a first portion of the payload, the one or more second outer code parities, to which an encoding is not applied in the physical layer, are generated based on a second portion of the payload, at least a part of the second portion is different from the first portion, the codeword includes the payload, the first outer code parity, and an inner code parity generated from at least part of the code block based on the inner code, and a number of the one or more second outer code parities in the circular buffer is determined according to a maximum size of the codeword or an amount of resources for transmission.

Abstract: A method of transmitting a signal by adaptively controlling windowing or filtering by a user equipment in a wireless communication system, includes the steps of receiving a message including a timing advance (TA) value from a base station, determining a windowing type or a filtering type corresponding to the TA value, and transmitting an uplink signal to which the determined windowing type is applied. In this case, the windowing type is distinguished according to a length of a valid symbol and the filtering type can be distinguished according to a filter coefficient value.
