Abstract

The invention relates to a 5G-oriented cluster cooperative communication heterogeneous system and an interference suppression method, the system comprises a macro base station and at least one base station cluster, the base station cluster comprises a head base station and N small base stations, and the head base station is respectively connected with the N small base stations and the macro base station; the macro base station is connected with the core network; the head base station is used for sending a first message to the cooperative small base station after determining that the target user equipment establishes a connection with the target small base station, the first message carrying first position information, and the first message being used for indicating that the target user equipment has established a connection with the target small base station; each small base station in the N small base stations is used for establishing connection with the user equipment; the small base station determines a target direction according to the first position information; when the small base station sends a message to the user equipment, the small base station sends the message to directions except the target direction based on beamforming processing; and the macro base station is used for realizing communication between the user equipment and the core network through the head base station and the small base station after the small base station is connected with the user equipment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a 5G-oriented cluster cooperative communication heterogeneous system and an interference suppression method. Background technique [0002] With the popularization of the application of Internet of Things technology, the demand for mobile communication wireless data transmission has exploded. In a densely deployed Heterogeneous Network (HetNets for short) system, co-channel interference is an important problem that inhibits the improvement of network performance. [0003] In a densely deployed heterogeneous network system, the core network is usually connected to a macro base station (Macro Base station, referred to as MBS), the macro base station is connected to multiple small base stations (Small Base station, referred to as SBS), and the small base station is connected to the user equipment (User Equipment). Equipment, referred to as UE) connection. [0004] However, i...
