Repeater
First Claim
1. A repeater, comprising:
- a local unit that comprises a base station interface unit, multiple local basic units connected to the base station interface unit, and a controller connected to the multiple local basic units; and
a remote unit that comprises multiple remote basic units, wherein the multiple remote basic units are arranged as an array and the multiple remote basic units are in one-to-one correspondence with the multiple local basic units;
wherein the base station interface unit is configured to receive a downlink signal sent by a base station and to send the downlink signal to the multiple local basic units;
wherein the controller is configured to generate a downlink signal phase for each remote basic unit according to a down-tilt angle and/or azimuth angle of the downlink signal instructed by a control instruction;
wherein the multiple local basic units each are configured to perform, according to a downlink signal phase generated by the controller for a corresponding remote basic unit, phase adjustment on the downlink signal sent by the base station interface unit, and to send the downlink signal after the phase adjustment to the corresponding remote basic unit;
wherein the multiple remote basic units each are configured to receive a downlink signal sent by a corresponding local basic unit and to send the downlink signal;
wherein the multiple remote basic units each are further configured to receive an uplink signal and to send the uplink signal to a corresponding local basic unit;
wherein the controller is configured to generate an uplink signal phase for each remote basic unit according to a down-tilt angle and/or azimuth angle of the uplink signal instructed by a control instruction;
wherein the multiple local basic units each are further configured to perform, according to a uplink signal phase generated by the controller for a corresponding remote basic unit, phase adjustment on an uplink signal sent by the corresponding remote basic unit, and to send the uplink signal after the phase adjustment to the base station interface unit; and
wherein the base station interface unit is further configured to send uplink signals, which are sent by the multiple local basic units to the base station.

Abstract
Embodiments of the present invention provide a repeater, including a local unit and a remote unit. The local unit includes a base station interface unit, multiple local basic units and a controller. The remote unit includes multiple remote basic units. The controller is configured to generate, according to a down-tilt angle and/or azimuth angle of a downlink signal instructed by a control instruction, a downlink signal phase for each remote basic unit. The multiple local basic units each are configured to perform, according to the downlink signal phase generated by the controller for a corresponding remote basic unit, phase adjustment on the downlink signal sent by the base station interface unit. The multiple remote basic units each are configured to receive the downlink signal sent by a corresponding local basic unit and to send the downlink signal.
