Abstract: A wireless transmit receive unit (WTRU) may be configured to receive an indication/configuration from a network regarding changes in information related to the serving cell's identity (e.g., Physical cell identity (PCI), Cell Global Identity (CGI), etc.), which may contain additional information such as the conditions when this change becomes effective. Upon the reception of this indication, and if a condition is also specified, fulfillment of the condition, the WTRU may be configured to consider the new PCI/CGI as the serving cell's PCI/CGI, consider the old PCI as belonging to a neighbor cell, and/or may update the security keys that are used for encryption and integrity protection based on the new PCI.

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 systems are disclosed for reducing control signaling in uplink transmissions. A device, such as a wireless transmit/receive unit, may determine to use a demodulation reference signal (DM-RS) transmission schedule out of a plurality of DM-RS transmission schedules. The DM-RS transmission schedule may be characterized by a DM-RS transmission being mapped to a single orthogonal frequency-division multiplexing (OFDM) symbol per subframe of a data stream. The DM-RS transmission schedule may be characterized by a DM-RS transmission being mapped to a first subset of subcarriers of an OFDM symbol of a subframe of a data stream and Physical Uplink Shared Channel (PUSCH) transmission or Physical Uplink Control Channel (PUCCH) control information being mapped to a second set of subcarriers of the OFDM symbol. The first set of subcarriers may be different than the second set of subcarriers. The data stream may be transmitted according to the DM-RS transmission schedule.

Abstract: Methods, apparatus, and systems are described for new radio (NR) sidelink resource allocation, e.g., for power saving and bandwidth part (BWP) operations. According to some aspects, different types of resource sets and signaling (e.g., preferred, non-preferred, resource conflict, etc.) may be considered and it may be indicated to user equipment (UE) which type of resources should be used based on certain criteria, e.g., least power consumption criteria.

Abstract: Methods, systems, and apparatus for supporting uplink Transmission Time Interval (TTI) bundling in Long Term Evolution (LTE) are provided. Methods, systems, and apparatus for signaling, activation/deactivation, and wireless transmit/receive unit (WTRU) behavior are also provided. In an example, a downlink control information (DCI) associated with a repeated physical uplink shared channel (PUSCH) transmission may be received. A hybrid acknowledgment repeat request (HARQ) process information may be determined using the received DCI. A repeated PUSCH transmission may be sent in accordance with one or more time units, the repetition configuration, and the HARQ process information.

Abstract: Systems and methods are contemplated for reconfiguration of one or more MAC instances while the WTRU is operating using dual- or multi-MAC instance connectivity. For example, upon reception of RRC reconfiguration information that modifies one or more secondary MAC instances, the WTRU may transmit a reconfiguration complete message to a Macro eNB (MeNB) and may synchronize to small-cell or secondary eNB (SeNB), for example if triggered by one or more of an RRC flag, a physical downlink control channel (PDCCH) order (MeNB/SeNB), MAC activation information, etc. For example, the WTRU may synchronize to the SeNB for specific type(s) of RRC reconfigurations, but not other type(s) of RRC reconfigurations. Although examples may be described in terms of dual connectivity, the WTRU may establish connectivity and perform mobility procedures with more than two radio access network (RAN) nodes (e.g., eNBs), and the embodiments described may be equally applicable to those scenarios.

Abstract: Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

Abstract: Radio network Positioning Reference Signals (PRSs) may be managed dynamically via user equipment (UE) requests triggered by measurements in accordance with initial PRS configurations, whereby a UE contacts an Access and Mobility Management Function (AMF) and/or a Location Management Function (LMF). Similarly, an LMF may initiate adjustments in PRS configurations and transmission via communications with base stations, UEs, and/or AMFs. Dynamic signaling of PRS configurations may be achieved via legacy protocols and/or New Radio Positioning Protocol A (NRPPa), for example. A requests from a UE for PRS configuration adjustment may include an indication of a required level of service or of a class of service, for example, and/or an indication of signal measurements, a position estimate, an indication of a capability of the UE.

Abstract: Methods, apparatuses, systems, and/or procedures for reference signal (RS) transmissions and receptions in wireless communications (e.g., 5G NR) are disclosed. For example, a method implemented by a wireless transmit/receive unit (WTRU) includes receiving configuration information indicating a set of RS resources, a set of candidate RS resources, and a threshold; receiving a first RS in an RS resource of the set of RS resources; selecting a candidate RS resource from the set of candidate RS resources, based on a determination that a measurement result of the received first RS is less than or equal to the threshold; and receiving a second RS in the selected candidate RS resource.
