摘要： A user equipment (UE) associated with a non-terrestrial network (NTN) is disclosed. The UE comprises a processor configured to determine a first time offset, based on processing a timing offset indication signal comprising the first time offset or an associated parameter, received from a base station. In some embodiments, the first time offset is indicative of a time delay in downlink (DL) to uplink (UL) interaction between the UE and the base station. The processor is further configured to determine a second time offset, based on processing a subsequent timing offset indication signal comprising the second time offset or an associated parameter, received from the base station at a subsequent time instance. In some embodiments, the processor is further configured to update the first time offset with the second time offset.

摘要： According to some embodiments, a method performed by a wireless device operating in a non-terrestrial network (NTN) comprises obtaining a first timing advance (TA) value for uplink transmission in the NTN. The first TA value comprises a reference TA value. The method further comprises obtaining a trigger condition for reporting a TA used by the wireless device for uplink transmission in the NTN and autonomously obtaining an adjusted TA value for uplink transmission. The adjusted TA is obtained via autonomous adjustment to the reference TA value based on a propagation delay between the wireless device and a serving satellite of the NTN. The method further comprises, upon determining the trigger condition for reporting the TA is satisfied, reporting the adjusted TA to a network node.

摘要： This application discloses a NB-IoT-based communication method and an apparatus, to evolve a NB-IoT communication technology into an NTN. The method is as follows: A terminal device generates an uplink signal, including a superframe which includes a synchronization sequence located in first duration of the superframe and a data frame located in second duration which is after the first duration, the synchronization sequence successively includes a first sequence repeated Ni times and a second sequence repeated N2 times, the second sequence is obtained by multiplying the first sequence by −1, a part of consecutive sequences of the synchronization sequence are used as a first synchronization reference sequence that is obtained based on the second sequence repeated N2 times and one or more first sequences that are sorted from back to front in the first sequence repeated N1 times. The terminal device sends the uplink signal to a network device.

摘要： A method for performing a handover operation includes using one or more processors of a non-terrestrial node to initiate communication with a first terrestrial node of a network, the terrestrial node having a first unique node identifier and a cell identifier and store a mapping that associates the first unique node identifier with the cell identifier. The method also includes using the one or more processors to receive an indicator that the mapping is subject to change and update the mapping to associate a second unique node identifier of a second terrestrial node of the network with the cell identifier based on the received indicator.

摘要： A multiple-access transceiver handles communications with mobile stations in environments that exceed mobile station design assumptions without necessarily requiring modifications to the mobile stations. One such environment is in Earth orbit. The multiple-access transceiver is adapted to close communications with mobile stations while exceeding mobile station design assumptions, such as greater distance, greater relative motion and/or other conditions commonly found where functionality of a terrestrial transceiver is to be performed by an orbital transceiver. The orbital transceiver might include a data parser that parses a frame data structure, a signal timing module that adjusts timing based on orbit to terrestrial propagation delays, frequency shifters and a programmable radio capable of communicating from the Earth orbit that uses a multiple-access protocol such that the communication is compatible with, or appears to the terrestrial mobile station to be, communication between a terrestrial cellular base station and the terrestrial mobile station.

摘要： An Automatic Dependent Surveillance-Broadcast (ADS-B) device may include a controller and a radio frequency (RF) transmitter coupled thereto and configured to transmit flight identification data, and transmit flight position data at a coarse accuracy and a fine accuracy. The RF transmitter may be configured to operate at a frequency within the L-band Digital Aeronautical Communications System (LDACS) frequency band. For example, the controller may be configured to encapsulate the flight identification data and flight position data within a message for an LDACS.

摘要： An apparatus for establishing communication between a base station and different generation terminals includes a multi-protocol stack capable of processing user traffic received from different generation terminals. The apparatus also includes a common physical layer that receives user traffic from different generation terminals and identifies the generation of the terminal sending the user traffic. The user traffic is then processed and routed based on the terminal generation. Traffic can be prioritized across current and legacy terminal types based on a variety of factors.

At least some of the mobile nodes with mobile wireless communication and satellite communication are dynamically-switched between operating as an ordinary node or as a backbone node. All of the mobile nodes communicate over a dynamically-formed ordinary communication link. Mobile nodes operating as backbone nodes additionally communicate over a dynamically-formed backbone link. Data is routed in the network by an ad-hoc multi-interface dynamic routing which routes data between the mobile nodes by mobile wireless communication and by satellite communication in accordance with respective communication capabilities of the mobile nodes, so as to incorporate satellite communications into the network.
