Abstract

A random access method and device, in the random access method, when the association relationship between a downlink signal and a random access opportunity is that one downlink signal corresponds to multiple random access opportunities, multiple random access opportunities are determined through the first indication information Among the random access opportunities, the first random access opportunity is specifically used for sending the random access preamble. When the association relationship between the downlink signal and the random access opportunity is that multiple downlink signals correspond to one random access opportunity, the downlink signal can be determined among the multiple downlink signals through the second indication information, and the random access opportunity corresponding to the downlink signal can be determined. The opportunity serves as the first random access opportunity, and the random access preamble is sent by using the first random access opportunity. Through the above random access method, the first random access opportunity can be relatively accurately determined, and further the random access resource for random access can be relatively accurately determined.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a random access method and device. Background technique [0002] The development of mobile services has higher and higher requirements on the data rate and efficiency of wireless communication. In future wireless communication systems, beamforming technology is used to limit the energy of transmitted signals within a certain beam direction, thereby increasing the efficiency of signal transmission and reception. [0003] In the future fifth-generation mobile communication technology (5G) system, network equipment may use multiple beams to transmit information with terminals within the coverage area. Before information transmission is performed between a network device (such as a base station) and a terminal, the terminal first accesses the network device. Currently, the terminal usually accesses the network device through a random access (random access, RA)...
