摘要： A receiver and a method for receiving a radio communication is disclosed. The method includes receiving a burst encoded with a robust modulation coding scheme (MCS) as RX signals; generating, for each of the RX signals, a burst SNR, soft decision symbols and a packet; weighing, each of soft decision symbols with a respective burst SNR, to calculate soft combined symbols that are used to generate a Maximal-Ratio Combining (MRC) packet; and selecting, from the packets and the MRC packet, a CRC passed packet as an output. An adaptive dual burst transmitter is disclosed.

摘要： A system and method for communicating with an Internet Of Things (IoT) device via a satellite link. The method includes assigning a transmission mode to a physical channel, where the physical channel supports multiple timeslot durations and the transmission mode is selected from a single user (SU) or a multi-user (MU); selecting a timeslot duration from the multiple durations for a payload; obtaining, when the transmission mode is SU, a timeslot grant for use of the physical channel for the timeslot duration; and transmitting a burst including the payload, where the burst is transmitted synchronized with the timeslot grant when the transmission mode is SU and the burst is transmitted without synchronization when the transmission mode is MU.

摘要： An approach provides for conversion of global positioning system (GPS) data. A user terminal receives positioning data from a base station, wherein the positioning data is received in a second format, and wherein the second format was derived from ephemeris data broadcast via a global positioning system (GPS) in a first format. The user terminal converts the positioning data from the second format into a third format that is compatible with a protocol of the GPS system, and determines a first fix using the third format of the positioning data.

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 system and method for interfacing a User Equipment (UE) to a Core Network (CN) is disclosed. The method including: providing a high latency connection; providing a satellite network portal (SNP) to connect to the UE via a satellite link, wherein the SNP includes a Media Access Control (MAC) layer for managing the satellite link and a Radio Layer Control (RLC) layer of the UE; interfacing the UE to the CN with a Point of Presence (POP) including a Radio Resource Control (RRC) layer of the UE and a Packet Data Convergence Protocol (PDCP) layer of the UE; and establishing a session between the CN and the UE via the RRC layer, the PDCP layer and the RLC layer. In the method, network traffic, between the SNP and the POP, over the high latency connection has a latency greater than 10 milliseconds (ms), the session does not timeout due to the latency of the high latency connection, and the MAC layer schedules bandwidth for the establishing over the satellite link.
