Initial access method, initial access device and communication equipment

Abstract

The invention provides a method and a device applied to an initial access network of a terminal, a method and a device applied to an initial access network of a base station, and communication equipment. The method applied to an initial access network of a terminal comprises the following steps: sending first random access information to a base station, the first random access information comprising first transmission information of second random access information to be received; receiving second random access information sent by the base station, wherein the second random access informationcomprises second transmission information for sending the second random access information; and when the first transmission information is consistent with the second transmission information, sendingthird random access information by utilizing the first transmission information so as to carry out initial access. The random access information sent by the terminal can be correctly received by the base station, so that the initial access of the terminal and the base station is completed, the access delay requirement is ensured, and the terminal can save more power.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular, to a method and device for initial network access of a terminal, a method and device for initial network access of a base station, and a communication device. Background technique [0002] Currently, the research and development of the 5th generation mobile communication system (5G) is in full swing. According to future application requirements, the 5G system needs to support a variety of business scenarios, including eMBB (Enhanced Mobile Broadband, enhanced mobile broadband), URLLC (Ultra-reliable and Low Latency Communications, high reliability and low delay) and MMTC (Massive Machine Type of Communication, large-scale machine communication). Since licensed spectrum resources are very limited, unlicensed spectrum will also be used for data transmission in the 5th standard, which can provide a larger transmission bandwidth than licensed spectrum, especially for ...

Problems solved by technology

However, the disadvantages of unlicensed spectrum are also obvious. Because it should follow the LBT (listen before talking, listening and avoiding) mechanism, the LBT mechanism is a channel access mechanism, because the availability of channels on unlicensed spectrum cannot be guaranteed at all times. LBT requires to monitor the channel before transmitting data, conduct idle channel assessment, and then transmit data after ensuring that the channel is idle, so the effect of guaranteeing the delay is not very ideal
