Abstract

The invention discloses a method and equipment for determining arrival angles of antenna arrays. The method comprises the following steps: receiving at least one training sequence transmitted by base station equipment through a receiving antenna array by mobile terminal equipment, wherein one training sequence is transmitted in each time slot, and the training sequences are transmitted after being subjected to beam forming processing by the base station equipment; combining the received at least one training sequence; estimating channel impulse responses of a transmitting antenna array of the base station equipment and the receiving antenna array of the mobile terminal equipment according to the combined training sequences; and estimating arrival angle information of the receiving antenna array of the mobile terminal equipment with the channel impulse responses. Respective arrival angles are estimated through the training sequences transmitted between the base station equipment and the mobile terminal equipment, so that the time delay overhead of angle value estimation is reduced; the method and the equipment can be suitable for a millimeter-wave system under a large scale of antenna arrays; signal transmission with a millimeter-wave band is realized; and the signal transmission efficiency is increased effectively.

Description

technical field [0001] The present invention relates to the fields of wireless communication technology and multi-antenna technology, in particular to a method and equipment for determining the azimuth angle of an antenna. Background technique [0002] With the development of communication technology, people's demand for high-speed services has shown explosive growth, and traditional communication systems have been unable to meet the demand. However, in terms of the use of wireless spectrum resources, the utilization rate of microwave spectrum resources tends to be saturated. Therefore, the development and utilization of millimeter wave spectrum resources has become a hot issue. [0003] Specifically, the frequency range that millimeter wave spectrum resources can use is 30 GHz to 300 GHz, and the wavelength thereof is between 1 mm to 10 mm. Compared with microwave communication, millimeter wave communication has larger communication capacity, larger transmission bandwidth ...
