Abstract: 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: Disclosed are methods and apparatuses for transmitting and receiving data channels in a communication system. An operation method of a terminal in a communication system may comprise receiving, from a base station, resource allocation information of a plurality of physical uplink shared channels (PUSCHs) used for repetitive transmission of a same transport block (TB); identifying a position of each of the plurality of PUSCHs in a time domain based on the resource allocation information; and repeatedly transmitting the same TB to the base station at the position of each of the plurality of PUSCHs. Therefore, 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: Provided are a method and an apparatus for processing a transmission signal, which reduce a peak value to an appropriate magnitude by appropriately distorting a final transmission signal through implementation into simple hardware having a small memory and a small operation amount to effectively reduce a peak-to-average power ratio (PAPR) by effectively processing a signal for wireless communication in real time.

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: Disclosed are methods and apparatuses for transmitting data using a random access procedure in a communication system. An operation method of a terminal in a communication system includes transmitting a first MsgA including an RA preamble #i and a payload to a base station; receiving, from the base station, a MsgB including information indicating that an RA preamble #k is reserved; and transmitting a second MsgA including the RA preamble #k and data to the base station in a preamble reservation period associated with the RA preamble #k.

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.
