Abstract: Systems and methods described herein are provided for beamforming and uplink control and data transmission techniques. Such techniques enable a UE to maintain at least one beam process for operation with multiple beams and/or points. A beam process may be indicated for transmission or reception over a downlink or uplink physical channel. Power, timing, and channel state information may be specific to a beam process. A beam process may be established as part of a random access procedure in which resources may be provisioned in random access response messages. Techniques are provided to handle beam process failures, to use beam processes for mobility, and to select beams using open-loop and closed-loop selection procedures.

Abstract: Systems, methods, and instrumentalities are described herein that may be used to determine a destination for sidelink transmission based on the priority of the transmission and/or other parameters associated with the transmission. In examples, a destination may be selected if one or more logical channels associated with the destination have a bucket size parameter exceeding a certain threshold and the one or more logical channels have a highest priority. Various other techniques are also described herein that relate to the configuration and/or report of QoS information, selection of sidelink resources, use of a minimum communication range, etc.

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 disclosed for reliable control signaling, for example, in New Radio (NR). A receiver in a wireless transmit/receive unit (WTRU) may receive one or more physical downlink control channel (PDCCH) transmissions comprising downlink control information (DCI). The WTRU may determine a transmission profile associated with an uplink control information (UCI). Based on the transmission profile, the WTRU may determine one or more transmission characteristics associated with the transmission of the UCI. The WTRU may transmit the UCI over a physical uplink control channel (PUCCH). The UCI may be transmitted using transmission characteristics determined by the WTRU. The WTRU may transmit the UCI based on at least one of a control resource set (CORESET), a search space, or a radio network temporary identifier (RNTI). The WTRU may determine a transmission profile differently based on what the UCI may comprise.

Abstract: Systems, methods, and instrumentalities are disclosed herein for paging acquisition in multipath WTRU to network relays. A first WTRU may receive configuration information indicating information associated with a first monitoring pattern to use if a first condition is satisfied and information associated with a second monitoring pattern to use if a second condition is satisfied. The first condition and the second condition may be associated with a link quality associated with a second WTRU. The first WTRU may receive a first indication from the second WTRU. The first WTRU may determine that the first condition is satisfied. The first WTRU may send an indication of the first monitoring pattern. The first WTRU may monitor a first paging occasion in accordance with the first monitoring pattern. The first WTRU may receive a first paging message for the second WTRU in the first paging occasion. The first WTRU may send an indication of the received first paging message to the second WTRU.

Abstract: A first wireless transmit/receive unit (WTRU) may receive, from a second WTRU, sidelink control information (SCI), including first information indicating if a resource is reserved by the second WTRU, and second information indicating if the second WTRU is a power saving or non-power saving. The first WTRU may measure a reference signal receive power (RSRP) of signals transmitted by the second WTRU. The first WTRU may add a resource to a set of available resources if the first information indicates that the resource is not reserved by the second WTRU. If a resource is reserved, the WTRU may set an RSRP threshold to a first set or second threshold based on a power saving mode of the second WTRU. The first WTRU may add the resource to the set of available resources if the measured RSRP is less than the selected RSRP threshold.

Abstract: Channel access in unlicensed spectrum may be a function of the type of physical channel and/or a procedure that initiated a transmission. An LBT procedure may be performed as a function of beam management. A WTRU may access a channel using multiple channel access methods associated with multiple uplink transmissions based on a determination of persistent interference associated with the channel. Channel access methods may be performed with different parameters or characteristics based on the resource type/timing of the transmission/measurements of DL/UL RS. Channel access methods may be characterized by a sensing duration, an ED threshold, a beam width, and/or a beam direction. Different ED thresholds may be applied as a function of one or more characteristics of an applicable beam. Multiple sensing methods and/or related parameters may be applied as a function of the type of physical channel and/or the type of procedure associated with a transmission.

Abstract: Systems, methods, and instrumentalities are described for handling positioning reference signals in a wireless communication system. The positioning reference signals may be assigned priorities that may be used to facilitate various operations of a wireless transmit/receive unit (WTRU) such as positioning related services, collision avoidance, measurement and reporting, etc. The WTRU may be configured with multiple muting patterns associated with the positioning reference signals and may switch between different muting patterns based on the priorities of the positioning reference signals and/or other downlink (DL) or uplink (UL) transmissions that may overlap or collide with the positioning reference signals.

Abstract: A method and apparatus are described which perform bandwidth aggregation by simultaneously monitoring and processing a number of simultaneous, non-contiguous or contiguous component carriers in the downlink. A wireless transmit/receive unit (WTRU) can be configured by an evolved Node-B (eNodeB) to support additional component carriers. A pre-configured additional component carrier may be used. Various methods for activating and deactivating the additional component carrier are also described.
