Abstract
(EN)
A method and device for transmitting and receiving a signal in a wireless communication system, according to one embodiment of the present invention, comprises transmitting a physical random access channel (PRACH) and receiving a random access response (RAR) on the basis of the PRACH, wherein the PRACH is transmitted via one random access channel (RACH) occasion (RO) of ROs in a RACH slot, timing gap durations exist between the ROs, and the same timing gap durations can be set even if a PRACH format and/or a subcarrier spacing (SCS) used for the PRACH are changed.
(FR)
Un procédé et un dispositif d'émission et de réception d'un signal dans un système de communication sans fil, selon un mode de réalisation de la présente invention, comprennent la transmission d'un canal d'accès aléatoire physique (PRACH) et la réception d'une réponse d'accès aléatoire (RAR) sur la base du PRACH, le PRACH étant transmis par l'intermédiaire d'une occasion (RO) de canal d'accès aléatoire (RACH) des RO dans une fenêtre RACH, des durées d'intervalle de synchronisation existent entre les RO, et les mêmes durées d'Intervalle de synchronisation peuvent être établies même si un format PRACH et/ou un espacement de sous-porteuse (SCS) utilisé pour le PRACH sont modifiés.
