Abstract

The invention provides a random access method based on a difference beam, base station equipment and user equipment. The random access method based on the difference beam comprises the following steps: receiving a leading sequence from first UE (User Equipment) by the base station equipment through a difference beam receiving mode; based on the leading sequence, determining an angle deviation of a base station in a beam direction; and performing base station beam adjustment according to the angle deviation of the base station in the beam direction, and transmitting a random access response signal to the first UE through the adjusted base station beam. The random access method based on the difference beam provided by the invention detects the angle deviation of the base station in the beam direction through the difference beam receiving mode, which can adjust a receiving beam of the base station to an optimal beam more quickly than a beam polling mode in the prior art, thereby improving the performance of a random access process.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a random access method based on differential beams, base station equipment and user equipment. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and the Internet of Things (IoT, internet of things), it brings unprecedented challenges to future mobile communication technologies. For example, according to the report ITU-R M.[IMT.BEYOND 2020.TRAFFIC] of the International Telecommunication Union ITU, it can be predicted that by 2020, the growth of mobile traffic will increase by nearly 1,000 times compared to 2010 (4G era). UE (User Equipment, The number of user equipment) connections will also exceed 17 billion. As massive IoT devices gradually penetrate into mobile communication networks, the number of connected devices will become even more astonishi...
