Abstract
(EN) An apparatus and method for transmitting and receiving a signal in a Distributed Antenna System (DAS) is provided. A method for determining an initial state in a DAS includes receiving a value through high-level signalling and determining an initial state based on the value, in which the value includes a value in which is set an initial state of a scrambling sequence, which differs according to a transmission point.
(FR) L'invention concerne un appareil et un procédé d'émission/réception d'un signal dans un système d'antennes réparti (DAS). Un procédé de détermination d'un état initial dans un DAS consiste à recevoir une valeur par le biais d'une signalisation de haut niveau; et à déterminer un état initial sur la base de cette valeur. La valeur comprend une valeur dans laquelle est défini un état initial d'une séquence de brouillage, qui diffère selon un point d'émission.
