摘要： The present invention discloses a method and apparatus for random access in a relay system, comprising: a Relay Node (RN) determines whether a random access is triggered, if the random access is triggered, the RN performs the random access by using a non-backhaul link subframe. In the present invention, if the random access of the RN working in a base station state is triggered, the RN can perform the random access by using partial or all of non-backhaul link subframe resources, that is, the RN can perform the random access by using the subframes of the Uu interface. The method can reduce the time delay for performing the random access of the RN working as a base station and improve the user experience.

摘要翻译： 本发明公开了一种中继系统中随机接入的方法和装置，包括：中继节点（RN）确定是否触发随机接入，如果随机接入被触发，则RN通过使用非接入接入进行随机接入， 回程链路子帧。 在本发明中，如果在基站状态下工作的RN的随机接入被触发，则RN可以通过使用部分或全部非回程链路子帧资源来执行随机接入，也就是说，RN可以执行随机接入 通过使用Uu接口的子帧进行访问。 该方法可以减少执行作为基站工作的RN的随机接入的时间延迟并改善用户体验。
