Abstract: 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.

Abstract: A wireless transmit/receive unit (WTRU) receives first timing advances and first power control commands from a first eNodeB and second timing advances and second power control commands from a second eNodeB and transmits, to the first eNodeB, a first physical uplink control channel using a first uplink component carrier. The first physical uplink control channel has a first timing adjusted by the first timing advances but not by the second timing advances and a first power level adjusted by the first power control commands but not by the second power control commands. The WTRU transmits a second physical uplink control channel using a second uplink component carrier. The second physical uplink control channel has a second timing adjusted by the second timing advances but not by the first timing advances and a second power level adjusted by the second power control commands but not by the first power control commands.

Abstract: Methods and apparatuses for millimeter wave (mmW) beam acquisition are disclosed. An apparatus may include a processor and a transceiver configured to receive a plurality of signals. The plurality of signals may be swept over time using a respective plurality of beams, and each signal of the plurality of signals may include a sequence based on an index of a respective one of the plurality of beams. The processor and the transceiver may take a measurement of a first signal of the plurality of signals. The transceiver may transmit a measurement report including the measurement of the first signal of the plurality of signals and the index of a respective one of the plurality of beams.

Abstract: 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.

Abstract: Systems, methods, and instrumentalities are disclosed for power control for aerial wireless transmit receive units (WTRUs). Power control may be open loop and may be managed based on altitude. Open loop power control may be based partly on path loss estimation from neighboring cells and may be coordinated among interfering neighboring eNBs using path loss information. Dynamic power control may be driven by the WTRU. Reference signal transmissions by an eNB may use uplink resources for path loss estimation, and interference estimation may be based on uplink reference signals. Path loss estimation may be based on downlink reference signals. Dynamic blanking may be provided for Cell-specific Reference Signals (CRS), and random access (e.g. RACH) may be provided for aerial WTRUs.

Abstract: Methods and apparatus may perform dual-band or multi-band mesh operations. A dual-band mesh station (MSTA) capable of operating in an O-band and a D-band may seek to join a mesh network, and may receive O-band beacons from at least one MSTA in the mesh network, where the O-band beacons may include D-band mesh information. The joining MSTA may transmit D-band beacons in a time-period specified by the O-band beacon, and on a condition that a beacon response message is received, may further transmit D-band association information via O-band management frames to join mesh network on the D-band. The joining MSTA may perform contention-free scheduled access in the D-band while sharing D-band transmission information in the O-band to enable concurrent communication in the D-band by neighboring multi-band MSTAs.
