Abstract: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: The present specification provides a method for transmitting multiple uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, control information related to PUCCH resources for transmitting the multiple UCI, wherein the control information includes information related to a number of REs of the PUCCH resources, information related to a modulation order, and information related to a configured maximum code rate; determining a PUCCH resource for transmitting the multiple UCI by comparing a value obtained by multiplying the configured maximum code rate and the modulation order by the number of REs corresponding to the PUCCH resources indexed in ascending order with a size of a payload for the multiple UCI; and transmitting, to the base station, the multiple UCI on the determined PUCCH resource.
