Abstract: A system and methods for beam failure recovery and management for multi-carrier communications with beamforming are disclosed herein. A wireless transmit/receive unit (WTRU) may monitor for and detect a beam failure of a beam associated with a secondary cell (Scell). The WTRU may select an Scell candidate beam. The WTRU may transmit using a selected uplink (UL) resource in a primary cell (SpCell) a medium access control (MAC) control element (CE) including an indication of Scell beam failure and identifying the selected candidate beam. The WTRU may receive an Scell beam failure indication response on the SpCell indicating an SCell index and a downlink (DL) quasi co-location (QCL) reference associated with the Scell. The WTRU may verify that the DL QCL reference matches with the candidate beam. The WTRU may perform random access on the SCell using the selected QCL reference and the selected candidate beam.

Abstract: 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.

Abstract: 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.

Abstract: A method and apparatus for receiving a broadcast configuration indicating when a change in a RAN function termination occurs is provided, for example, by a timer value. The broadcast configuration may be received from a satellite, blimp or other moving transmitter. A dedicated configuration may also be received from the serving cell. The dedicated configuration may include a preamble, a transient configuration and an indication of a layer 2 behavior. If a WTRU detects a change in RAN function termination, the WTRU may suspend any uplink data transmissions, apply the transient configuration and transmit the preamble to a target cell. The WTRU may synchronize with the target cell and apply the layer 2 behavior.

Abstract: Systems, methods and instrumentalities are described herein with respect to the mobility and multi-connectivity of wireless transmit receive units. These devices may be configured to perform conditional handovers and/or conditional second cell group reconfigurations including primary secondary cell additions or changes. The devices may exchange information with a network while performing the conditional reconfigurations and/or conditional handovers. The devices may be configured with rules to handle concurrent handover and reconfiguration tasks.

Abstract: Methods and apparatuses are described herein for monitoring radio links between wireless transmit/receive units (WTRUs) and determining of radio link failure, and may be used, among others, for New Radio (NR) vehicular communication (V2X); a mode whereby WTRUs can communicate with each other directly. A radio link between a WTRU and another WTRU may be monitored independently per ongoing unicast and/or multicast link, and radio link failure (RLF) may be determined as a function of the monitoring.

Abstract: Light and/or Inactive state connectivity and/or autonomous mobility techniques are contemplated. A WTRU may, for example, have an inactive/idle mode, a light connected/loosely connected/Inactive mode and/or a connected/fully connected/Active mode. A WTRU in light connected mode may have a WTRU context stored in a RAN. A WTRU may perform an area monitoring procedure while in light connected state. A WTRU may engage in autonomous mobility during light connectivity. A WTRU may move within a logical area (e.g., a RAN paging area), perhaps without notifying the network. The WTRU may provide notice when it has moved outside a logical area (e.g., update RAN paging area). Mobility in light connected state may be network controlled (e.g., to enable handover when data transfer may be allowed and/or ongoing). A WTRU may be reachable during a light connectivity state. A WTRU may engage in autonomous mobility during light connectivity and/or an Inactive state.

Abstract: A wireless transmit/receive unit (WTRU) may communicate in a non-terrestrial network (NTN) comprising a plurality of satellites. The WTRU may be preconfigured with a plurality of measurement configurations and a corresponding plurality of activation/deactivation criteria associated with the plurality of satellites. The activation/deactivation criteria includes at least activation timing information. The WTRU may activate and deactivate each of the plurality of measurement configurations over time in accordance with the activation/deactivation criteria. The WTRU may perform measurements on cell beams for satellites with active measurement configurations and report results based on the measurements to NTN.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to measure a downlink quality associated with at least one first beam. The WTRU may be configured to determine whether the measured downlink quality associated with the at least one first beam is below a threshold value. The WTRU may be configured to receive at least one control channel transmission using a determined second beam, based on, in part, a determination that the measured downlink quality associated with the at least one first beam is below the threshold value. The determined second beam used to receive the at least one control channel transmission may be a same beam that is used to receive an associated data channel transmission. The determined second beam may be from a set of beams. The set of beams may be received via higher layer signaling.
