初始接入的方法及装置制造方法及图纸

本发明专利技术实施例提供了一种初始接入的方法及装置，该方法包括接入网设备采用至少两个下行波束向用户设备发送同步信号，同步信号包括至少两个下行波束的下行波束索引；接入网设备接收用户设备发送的随机接入前导序列；接入网设备采用至少两个下行波束向用户设备发送随机接入响应RAR消息，以完成用户设备的初始接入。采用本发明专利技术实施例提供的初始接入方法克服了在新无线系统中，高频传输环境下信道不稳定的缺点，从而提高NR系统的初始接入性能，进而提高系统用户体验。

Method and device for initial access

The embodiment of the invention provides a method and device for initial access, which comprises an access network device transmitting a synchronous signal to a user device using at least two downlink beams, a synchronous signal including a downlink beam index of at least two downlink beams, and an access network device receiving a random access preamble sequence transmitted by the user device; The access network device sends random access response RAR messages to the user equipment by at least two downlink beams to complete the initial access of the user equipment. The initial access method provided by the embodiment of the invention overcomes the shortcoming of channel instability in the high frequency transmission environment of the new wireless system, thereby improving the initial access performance of the NR system and thereby improving the system user experience.
