Abstract:
(EN) Provided in embodiments of the present application are a random access preamble transmitting method and device. The method comprises: a terminal device acquiring a scrambling sequence, performing scrambling on a random access preamble using the scrambling sequence, and transmitting the scrambled random access preamble to a network device. By performing scrambling on a random access preamble and transmitting the scrambled random access preamble by a terminal device, the technical solution effectively eliminates the inter-cell interference and addresses the potential problem of a false alarm of a target cell.
(FR) Selon certains modes de réalisation, la présente invention concerne un procédé et un dispositif de transmission de préambule d'accès aléatoire. Le procédé comprend les étapes suivantes : un dispositif terminal acquiert une séquence de brouillage, effectue un brouillage sur un préambule d'accès aléatoire à l'aide de la séquence de brouillage, et transmet le préambule d'accès aléatoire brouillé à un dispositif de réseau. En effectuant un brouillage sur un préambule d'accès aléatoire et en transmettant le préambule d'accès aléatoire brouillé par un dispositif terminal, la solution technique élimine efficacement les interférences intercellulaires et aborde le problème potentiel d'une fausse alarme d'une cellule cible.
(ZH) 本申请实施例提供一种随机接入前导码传输方法及装置,该方法包括:终端设备获取扰码序列,并使用该扰码序列对随机接入前导码进行加扰,最后将加扰后的随机接入前导码发送给网络设备。该技术方案中,通过终端设备对随机接入前导码进行加扰,并发送加扰后的随机接入前导码,有效消除了小区间的干扰,解决了可能存在的目标小区虚警问题。
