Patent number: 11637625Abstract: While suppressing a power consumption of an aerial-floating type communication relay apparatus, an interference in a multi-feeder link of a same frequency between the communication relay apparatus and plural gateway (GW) stations is suppressed. A relay communication station of the communication relay apparatus performs a first interference suppression process and a second interference suppression process by switching therebetween. The first interference suppression process suppresses an interference signal that causes an interference by a transmission signal transmitted from a gateway station and received with a directional beam corresponding to another gateway station, by using a propagation path response estimated with one frequency in a transmission signal band as an estimation frequency based on a reception result of a pilot signal without dividing a transmission signal band of a feeder link.Type: GrantFiled: February 13, 2020Date of Patent: April 25, 2023Assignee: HAPSMobile Inc.Inventors: Takafumi Fujii, Teruya Fujii

Patent number: 11595113Abstract: Satellites provide communication between devices such as user terminals (UTs) and ground stations that are connected to points-of-presence (PoP) connected to other networks, such as the Internet. The PoP accepts downstream data addressed to the UT. A representation of the communication resources that are expected to be used to pass the downstream data from the PoP to the UT is determined and executed on one or more processors. The representations may include representations of traffic shapers, modems, and so forth at different points in the network. The representations may consider real-world and simulated feedback data. Within the representation, traffic shaping is employed to determine preshaped data that includes resource metadata designating the communication resources to be used. The preshaped data is passed along to the actual communication resources for subsequent delivery. The preshaping substantially improves performance of constrained communication resources.Type: GrantFiled: September 1, 2020Date of Patent: February 28, 2023Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Andrew B.

Patent number: 11558915Abstract: The same or similar physical signals can be used for both user equipment (UE) and an integrated access backhaul (IAB) node. Different configurations of resources and/or transmission periods of the signals can be used for initial access for access UEs and IAB nodes.
