Abstract

The invention discloses a user terminal, a base station, a user terminal scheduling method, and a user terminal scheduling device. The scheduling method comprises the steps as follows: the base station performs unilateral beam training on each candidate user terminal, and receiving beam information fed back by each candidate user terminal; the base station determines beam correlation between the user terminals according to the received information, and groups all the candidate user terminals according to the determined beam correlation between the user terminals; and the base station selects the served user terminal in current scheduling from each user terminal set in a grouping result. By using the user terminal, base station, method and device provided by the invention, selection of thescheduling user and determination of the analog domain transmission and receiving beams do not need to acquire a high-dimensional analog channel state information (CSI) matrix in advance, so that theuser terminal scheduling taking the maximization of the system spectrum utilization rate as a target can be achieved under the relatively low algorithm complexity, and the extremely strong practicability is provided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a scheduling method and device for a user terminal, a base station and the user terminal thereof. Background technique [0002] In order to realize the vision of high-speed transmission in the 5G system, one of the basic means is to use a large block of untapped spectrum resources in the millimeter wave band. In order to solve the problem of excessive signal attenuation in millimeter-wave high-frequency transmission, massive MIMO technology combined with multi-user beamforming can generate transmit and receive beams with strong spatial directionality, and effectively compensate for the high path of millimeter-wave signals through high directional gain. damage. [0003] Beamforming is used for directional transmission or reception of signals between base stations and user terminals. It is a classic and traditional antenna technology and can be divided into ...
