Patent number: 11296809Abstract: A small cell interference coordination method and wireless communication device includes obtaining mobile information of at least one of the small cells. Relative movement between the small cells is determined according to at least the movement information. A Doppler frequency shift of a signal between small cells is estimated according to the relative movement. An interference alignment policy between small cells is implemented according to the estimated Doppler frequency shift.Type: GrantFiled: July 28, 2020Date of Patent: April 5, 2022Assignee: SONY CORPORATIONInventors: Liang Wu, Zaichen Zhang, Jian Dang, Yingying Yu, Weiwei Qin

Patent number: 10863519Abstract: A wireless communication method and device. The method includes receiving location information from one or more terminals served by a first base station, and identifying, according to the received location information, a first terminal located within the coverage range of the first base station and proximate to the coverage range of at least one second base station, the first terminal served by the first base station being capable of receiving an interference signal from the at least one second base station, and a second terminal served by a corresponding second base station and distant from the coverage range of the first base station existing within the coverage range of each of the at least one second base station. There is a cooperating with the at least one second base station to determine a downlink transmission mode for the first terminal.Type: GrantFiled: May 26, 2017Date of Patent: December 8, 2020Assignee: SONY CORPORATIONInventors: Liang Wu, Zaichen Zhang, Lili Zheng, Weiwei Qin, Jian Dang, Penshun Lu
