Abstract: Transmit and/or receive beamforming may be applied to the control channel transmission/reception, e.g., in mmW access link system design. Techniques to identify candidate control channel beams and/or their location in the subframe structure may provide for efficient WTRU operation. A framework for beam formed control channel design may support varying capabilities of mBs and/or WTRUs, and/or may support time and/or spatial domain multiplexing of control channel beams. For a multi-beam system, modifications to reference signal design may discover, identify, measure, and/or decode a control channel beam. Techniques may mitigate inter-beam interference. WTRU monitoring may consider beam search space, perhaps in addition to time and/or frequency search space. Enhancements to downlink control channel may support scheduling narrow data beams. Scheduling techniques may achieve high resource utilization, e.g., perhaps when large bandwidths are available and/or WTRUs may be spatially distributed.

Abstract: Methods and apparatuses are described herein for paring an unmanned aerial vehicle (UAV) with a UAV-controller (UAV-C). For example, a UAV having a UAV wireless transmit/receive unit (UAV WTRU) may transmit, to an access and mobility management function (AMF), a non-access stratum (NAS) request message that includes a paring request indication and a UAV-controller (UAV-C) identification (UAV-C ID). The UAV-C ID may be carried in a paring request to an unmanned aerial system (UAS) service supplier (USS)/UAS traffic management (UTM) for paring authorization of the UAV with a UAV-C associated with the UAV-C ID. The UAV may receive, from the AMF, a NAS response message that includes an unmanned aerial system (UAS) identification (UAS ID) indicating that the UAV is paired with the UAV-C, wherein the UAS ID is assigned by the USS/UTM.

Abstract: Method, apparatus and systems are disclosed. In one representative embodiment, a method may be implemented by a wireless transmit/receive unit (WTRU) for communication via a network access point (NAP). The method may include the WTRU receiving from the NAP a set of preambles and corresponding propagation delay related thresholds and determining propagation delay related information associated with a distance between the WTRU and the NAP or a location in a coverage of the NAP. The method may further include selecting a subset of preambles from the set of preambles based on the determined propagation delay related information, randomly selecting a preamble from the selected subset of preambles, and sending the randomly selected preamble to the NAP.

Abstract: Methods and systems for operation in a wireless network are provided, the methods including receiving modulated data symbols and zeros in a frequency-domain, and mapping in the frequency-domain the modulated data symbols and zeros in an interleaved manner to sub-carriers within a resource allocation. The methods and systems further include generating a time-domain data signal based on the mapped sub-carriers, and generating a time domain cancellation signal by sign inverting and repeating a predetermined number of time-domain samples at a tail portion of the data signal. The methods and systems further include combining the time-domain data signal and the time domain cancellation signal to generate an exact zero tail data signal such that the exact zero tail data signal has a zero tail length equal to the predetermined number of time-domain samples, and transmitting the exact zero tail data signal.

Abstract: Methods, devices and systems are provided for performing a random access (RA) procedure. A wireless transmit/receive unit (WTRU) may be configured to receive RA resource sets, where each of the RA resource sets is associated with a node-B directional beam, select an RA resource set from among the RA resource sets, and initiate an RA procedure based on the selected RA resource set. The RA procedure may include selecting multiple preambles which include a preamble for each resource of a plurality of resources corresponding to the selected RA resource set. The WTRU may be configured to sequentially transmit the selected multiple preambles in sequential RA transmissions, and may be configured to receive, from a node-B, in response to the RA transmissions, at least one RA response (RAR), where each of the received at least one RAR corresponds to one of the transmitted multiple preambles.
