Electronic device and communication method

Abstract

The present disclosure relates to an electronic device and communication method. An electronic device used in a first terminal device side is configured for acquiring configuration information of reference signals of a second cell from a first control device of a first cell, measuring the reference signals based on the configuration information and feeding back information indicating the space beams in the second cell interfering with the first terminal device to the first control device.

1 . An electronic device used in a first control device side of a wireless communication system including:
 a memory for storing computer instructions; and   a processing circuit configured to perform the computer instructions stored thereon for:   acquiring configuration information of reference signals of a second cell from a second control device in the second cell adjacent to a first cell controlled by the first control device, for a first terminal device in the first cell to determine interferences of space beams corresponded to the reference signals of the second cell to the first terminal device based on the configuration information;   acquiring information indicating the space beams interfering with the first terminal device from the first terminal device; and   performing interference coordination between the first cell and the second cell based on the acquired information indicating the space beams interfering with the first terminal device.   wherein performing interference coordination between the first cell and the second cell includes that the first control device notifies the second control device of the information indicating the space beams interfering with the first terminal device for the second control device to forbid those space beams.   
     
     
         2 . An electronic device used in a second control device side of a wireless communication system including:
 a memory for storing computer instructions; and   a processing circuit configured to perform the computer instructions stored thereon for:   notifying a first control device in the first cell adjacent to a second cell controlled by the second control device of configuration information of reference signals of the second cell, for a first terminal device in the first cell to determine interferences of space beams corresponded to the reference signals of the second cell to the first terminal device based on the configuration information;   acquiring information indicating the space beams interfering with the first terminal device in the second cell from the first control device; and   performing interference coordination between the first cell and the second cell based on the acquired information indicating the space beams interfering with the first terminal device.   wherein, performing interference coordination between the first cell and the second cell includes forbidding at least one of the space beams interfering with the first terminal device.   wherein forbidding at least one of the space beams interfering with the first terminal device includes forbidding the at least one of the space beams interfering with the first terminal device in intervals when the at least one of the space beams interfering with the first terminal device.   notifying one or more second terminal devices in the second cell of information indicating space beams to be forbidden, so that the one or more second terminal devices do not feedback information indicating those space beams to the second control device, wherein, the second control device notifies the second terminal device in the second cell with a priority lower than a predetermined threshold of the information indicating space beams to be forbidden.
