(EN) METHOD AND APPARATUS FOR RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEMS
(FR) PROCÉDÉ ET APPAREIL PERMETTANT UN ACCÈS ALÉATOIRE DANS DES SYSTÈMES DE COMMUNICATION SANS FIL
Abstract
(EN)
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long term evolution (LTE). A method for operating a base station in a wireless communication system is provided. The method includes determining a transmission beam of a terminal based on a preamble sequence received from the terminal, determining, an identifier for the transmission beam based on a preset mapping relationship, and transmitting, to the terminal, a random access response comprising the identifier for the transmission beam.
(FR)
L'invention concerne un système de communication de pré-5e génération (5G) ou de 5G pouvant prendre en charge des débits de données plus élevés, supérieurs à ceux d'un système de communication de 4e génération (4G) tel qu'un système d'évolution à long terme (LTE). L'invention concerne un procédé d'exploitation d'une station de base dans un système de communication sans fil. Le procédé consiste: à déterminer un faisceau de transmission d'un terminal sur la base d'une séquence de préambule reçue du terminal; à déterminer un identifiant pour le faisceau de transmission sur la base d'une relation de mappage prédéfinie; et à transmettre au terminal une réponse à une demande d'accès aléatoire comprenant l'identifiant pour le faisceau de transmission.
