摘要： A system and a method for directing a handover of communications in Radio Frequency (RF) networks at a UT. The method includes servicing a user terminal (UT) via a first network having a first coverage area; receiving, from the UT via the first network, a measurement report for a second network having a second coverage area based on a measurement configuration of the second network; sending, to the UT via the first network, a handover order for obtaining service from the second network; and establishing, via a second network RAN (radio access network), a service for the UT via the second network per the handover order. In the method, the first network may include either a terrestrial network (TN) or a non-terrestrial network (NTN), the second network may include other of the TN or the NTN, and the TN and the NTN are RF networks. In the method, the establishing is performed while the UT is disposed in an overlap area of the first coverage area and the second coverage area, and the measurement report may include a RF signal metric of the second network at the UT.

摘要： A system and method for operating a hybrid 4G satellite network. The method includes providing a NGSG including a satellite AS/NAS stack, a terrestrial 4G stack and a relay to connect the satellite AS/NAS stack and the terrestrial 4G stack; transporting a 4G traffic between a 4G UE and the NGSG using a satellite air interface; utilizing a terrestrial network between the NGSG and a 4G CN to transport the 4G traffic; and mapping, with the relay, the 4G traffic between the satellite AS/NAS stack and the terrestrial 4G stack and vice versa, where the satellite air interface is better suited for satellite communications than the terrestrial network. A system and method for multiplexing a first-generation UE and a second-generation UE on a satellite channel.

摘要： A method for communicating with a legacy terminal supporting a legacy air interface and a new terminal supporting a next generation air interface including: assigning a same carrier to the legacy terminal and the new terminal; receiving a terminal identifier and an optional payload for transmission at a MAC/RLC layer; determining if the terminal identifier is associated with the legacy terminal or the new terminal; composing, based on the determining, a burst header; formatting, a burst including the burst header and the optional payload; and transmitting the burst. In the method, the burst header is set to one of the one or more valid burst headers when the burst is associated with the legacy terminal, and the burst header is set to one of the one or more undefined burst headers when the burst is associated with the new terminal.

摘要： A method for reducing retransmission of packets by a sender is disclosed. The method includes: providing a network comprising a physical layer, a medium access control (MAC) layer and an Radio Link Control (RLC) layer; providing a retransmission packet in the physical layer, wherein the retransmission packet comprises a flow having a reordering feature in the RLC layer; enabling Hybrid Automatic Repeat reQuest (HARQ) in the physical layer and the MAC layer; receiving a HARQ request for a retransmission; and transmitting a new packet with the physical layer in response to the HARQ request, when the reordering feature for the flow in the retransmission packet is disabled.
