Patent number: 11050888Abstract: A system and method in various embodiments implements a virtual spectrum band stacking technique facilitating spectrum sharing by converting and combining spectrum bands consisting of several different RF channels, common air interfaces, and radio channel protocols in the radio frequency channel domain to form IP Virtual Radio Channels (IP-VRCs) in the packet data domain. This virtual spectrum stacking technique combines the transmissions of contiguous and non-contiguous RF channels with differing physical layers into IP-VRCs. This technique enables simultaneous parallel high-speed wireless transmission; virtual radio channel hopping for enhanced security; and customized security schemes for different IP-VRC Groups.

Patent number: 11012212Abstract: A method and a system of setting up a reference signal in a radio communication system are disclosed. The radio communication system includes a serving cell and a neighboring cell, and a mobile terminal of the serving cell uses the same temporal frequency resource to receive a serving resource block from the serving cell and an interference resource block from the neighboring cell. The method includes setting up a user-specific reference signal in the interference resource block and puncturing at the same temporal frequency position as the temporal frequency position at which the user-specific reference signal is set up on the interference resource block of the serving resource block to prevent any signal from being transmitted at the punctured temporal frequency position. When the method and the system are used and the interference power between cells is measured, it is possible to effectively reduce feedback overhead in a coordinated beamforming.Type: GrantFiled: December 16, 2019Date of Patent: May 18, 2021Assignee: Sun Patent TrustInventors: Hui Tong, Ming Xu, Masayuki Hoshino, Daichi Imamura
