Abstract: Feedback methods for repetitive uplink transmissions in a communication system are disclosed. An operation method of a terminal may comprise receiving DL data #1 from a base station through a DL data channel #1; receiving DL data #2 from the base station through a DL data channel #2; and when each of a UL control channel #1 on which an HARQ response #1 for the DL data #1 is to be transmitted and a UL control channel #2 on which an HARQ response #2 for the DL data #2 is to be transmitted overlaps with a UL data channel assigned by the base station, transmitting the HARQ response #1 and the HARQ response #2 to the base station through the UL data channel. Therefore, the performance of the communication system can be improved.

Abstract: A base station divides a subframe into a downlink time duration for downlink, an uplink time duration for uplink, and a guard period between the downlink time duration and the uplink time duration. The base station transmits a downlink control channel including information on a downlink packet duration allocated for downlink transmission of a terminal and information on an uplink packet duration allocated for uplink transmission of the terminal to the terminal in the downlink time duration.

Abstract: Disclosed are a method and an apparatus for uplink transmission in a communication system. An operation method of a terminal includes: receiving, from a base station, first SFI information indicating n flexible symbol(s); receiving, from the base station, second SFI information re-indicating m symbol(s) of the n flexible symbol(s) as uplink (UL) symbol(s); and transmitting an SRS to the base station through the m symbol(s) re-indicated as a UL symbol among the n flexible symbol(s) indicated as a flexible symbol. Therefore, performance of the communication system can be improved.

Abstract: In a system supporting narrowband Internet of things (NB-IoT), a terminal maps an uplink reference signal to a plurality of resource elements in a scheduled resource allocation unit, and transmits the uplink reference signal mapped to the plurality of resource elements. Here, the scheduled resource allocation unit includes a first number of contiguous slots in a time domain and a second number of contiguous subcarriers in a frequency domain.

Abstract: Disclosed are various methods for transmitting or receiving data or control information having high reliability conditions. A method for operating a terminal which transmits uplink control information (UCI) includes: a step of generating UCI; a step of comparing the priority of an uplink (UL) control channel for the transmission of the UCI with the priority of a UL data channel when some symbols of the UL control channel and the UL data channel overlap; and a step of selecting the UL channel having a higher priority among the UL control channel and the UL data channel, and transmitting the UCI to a base station through the selected UL channel.

Abstract: An LDPC decoding method of a received signal including a plurality of received symbols is provided. A decoding apparatus selects a perturbation space in which perturbation is to be performed based on a code length of the received signal and a maximum number of perturbation rounds indicating a number of perturbation rounds that can be performed, and performs a perturbation round. The decoding apparatus performs perturbation on a corresponding received symbol among the plurality of received symbols in each perturbation round, and decodes the received signal on which the perturbation has been performed. The decoding apparatus determines that decoding is successful when there is a perturbation round in which a decoding result of the received signal satisfies a predetermined condition.
