Abstract

The application discloses an uplink access method, a user device and a base station. According to the application, the method includes the following steps: in the course of a user device initially and randomly accessing a high-frequency base station, the high-frequency base station allocating non-competitive sequence to the user device, and transmitting the non-competitive sequence to the user device through a first random access response message; if the user device completes initial and random access to the high-frequency base station, in the training course of periodic beam forming, the high-frequency base station, on the basis of each receiving wide beam of the high-frequency base station, detecting the non-competitive sequence that is transmitted by the user device, determining the best receiving wide beam of the high-frequency base station and the best transmitting narrow beam of the user device, the high-frequency base station transmitting a second random access response message to the user device. According to the application, the method controls system overheads, ensures precision of beam training, and increases the properties of a high-frequency communication system.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to an uplink access method, user equipment and a base station. Background technique [0002] With the continuous improvement of data transmission rate and communication quality requirements for mobile communications, the existing frequency bands for mobile communications have become very crowded. However, in the millimeter wave frequency band of 6-300GHz, there are still a large number of spectrum resources that have not been allocated for use. Introducing the millimeter wave frequency band into cellular access communications and making full use of the large bandwidth resources of the millimeter wave frequency band is one of the important research directions for the next generation of 5G (5-Generation) mobile communication technology. [0003] In the existing research, the high-frequency band represented by the millimeter-wave frequency band is mainly used in ind...
