摘要： A method performed by a wireless transmit/receive unit (WTRU) may include receiving a configuration message including timing information for monitoring at least a subset of a plurality of beams to receive a set of synchronization signals and receiving the set of synchronization signals based on the timing information. The received set of synchronization signals include a primary synchronization signal and a secondary synchronization signal. The method may include receiving a reference signal along with a physical broadcast channel (PBCH) transmission. The reference signal comprises a sequence that is derived from an index associated with one of the at least the subset of beams and associated with the received set of synchronization signals. The method may include transmitting a random access channel (RACH) transmission. The RACH transmission includes a preamble sequence corresponding to the one of the subset of the plurality of beams.

摘要： An unmanned aerial system (UAS) may execute a mission planned by a UAS traffic management (UTM) system. The UAS may receive a mission planning response message from the UTM that includes a mission route for the UAS to navigate and a configuration of one or more trigger events. The mission route may be made up of a sequence of waypoints in an airspace. Each of the waypoints may be configured with a dynamic path conforming profile (PCP) a dynamic required navigation performance (RNP) value. The UAS may monitor at least the RNP value in one or more time intervals to determine if a trigger event occurs. The UAS may transmit a path conformance status report to the UTM upon determining that a trigger event of the one or more trigger events occurred. The path conformance status report may indicate conformance to one or more parameters specified in the PCP.

摘要： Methods and apparatuses are described herein for providing Hybrid Automatic Repeat Request (HARQ) techniques for a non-terrestrial network. For example, a wireless transmit/receive unit (WTRU) may transmit, to a satellite base station (BS), uplink (UL) feedback that includes configuration information for redundancy versions (RVs) and cross redundancy versions (cRVs). The WTRU may receive one or more first RVs associated with a first transport block (TB). The WTRU may receive one or more second RVs associated with a second TB and at least one cross redundancy version (cRV) associated with the first TB and second TB. The cRV may include parity bits generated from both the first TB and second TB. If at least one of the first TB or the second TB is unsuccessfully decoded, the WTRU may decode the first TB and second TB jointly based on the at least one cRV.

摘要： A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.

摘要： A wireless transmit/receive unit (WTRU) may include one or more antennas and a first transceiver operatively coupled to the antennas. The one or more antennas and the first transceiver may be configured to receive a first signal from a network using zero energy from the WTRU. The one or more antennas and the first transceiver may be further configured to extract energy from the first signal. The first transceiver may be further configured to examine a separation between energy threshold events to decode an energy signature of the first signal. The first transceiver may be further configured to activate a second transceiver operatively coupled to the one or more antennas if the decoded energy signature matches a stored energy signature, wherein the second transceiver is powered by the WTRU. The one or more antennas and the second transceiver may be configured to receive a second signal from the network.

摘要： Systems and methods for enabling proximity services to be delivered as part of an application service and/or for providing tailored services and/or a differential quality of service (QoS) to a flow may be disclosed. For example, a temporary service name between an application and a server such as a D2D server may be established such that a UE and/or network may execute such a service at a later time without later involvement by the application and/or without exchanging credentials for the application with the network and vice versa.

摘要： Methods and apparatuses are described herein that facilitate mesh network communication by a millimeter wave base stations (mBs) or WTRUs as nodes of a directional mesh network with other nodes of the directional mesh network. The mB or WTRU may include a directional antenna configured to transmit and receive signals in specific directions during the mesh network communication to define a directional mesh network. The mBs or WTRUs may transmit transmission request messages to neighbor nodes, wherein the transmission request messages include transmission slot allocation bitmaps and channel quality indicator information (CQI). Then response messages from the neighbor nodes may be received, wherein the response messages include receive slot allocation bitmaps and resource allocation decisions. The mBs or WTRUs may then update their transmission slot allocation bitmaps based on the received response messages and transmit data packets in specific directions based on the updated transmission slot allocation bitmap.

摘要： A wireless transmit/receive unit (WTRU) may receive from a network resource allocation information for device to device (D2D) communication. The WTRU may select, from the received resource allocation information for a transmission time interval (TTI), resources for a D2D channel. The WTRU may transmit, with use of the selected resources, data directly to another WTRU.

摘要： A method for use by an S-REDS may comprise quasi-omni broadcasting a multi-relay channel measurement request to one or more RDSs. The S-REDS may receive a first multi-relay channel measurement report from a first RDS of the one or more RDSs. The first multi-relay channel measurement report may contain first channel measurement information associated with a channel between the first RDS and the S-REDS. The S-REDS may further receive a second multi-relay channel measurement report from the first RDS of the one or more RDSs. The second multi-relay channel measurement report contains second channel measurement information associated with a channel between the first RDS of the one or more RDSs and a D-REDS.
