Abstract: A relay wireless transmit/receive unit (WTRU) may receive a direct communication request (DCR) from a remote WTRU requesting connectivity service (e.g., connectivity session parameters such as single-network slice selection assistance (S-NSSA!), data network name (DNN)). The relay may determine that the connectivity session for the service is subject to a secondary authentication and authorization (A&A), based on an indication associated with the connectivity session if already established and/or an indication associated DN from relay proximity service (ProSe) configuration. Based on the determination, the relay may trigger a network-controlled authorization for the remote WTRU. The relay WTRU may send a direct communication accept (DCA) message including a pending secondary A&A. and configure a traffic filter associated with the connection (e.g., a PC5 link) to discard data traffic from the remote WTRU until a successful completion of the secondary A&A.

Abstract: Methods and apparatus for burst transmission are provided. A wireless transmit/receive unit (WTRU) is configured to receive configuration information for a periodic search space (P-SS) and a semi-persistent search space (SP-SS). The configuration information may include a monitoring periodicity of the P-SS and a monitoring periodicity of the SP-SS. The P-SS may be associated with the SP-SS. The WTRU is configured to monitor the P-SS with the periodicity of the P-SS. The WTRU is configured to receive a first message in a first physical downlink control channel (PDCCH) in a slot of the P-SS. The first message may indicate an activation of the associated SP-SS. The WTRU is configured to monitor the SP-SS using the periodicity of the SP-SS. The WTRU is configured to receive a second message in a second PDCCH in a slot of the SP-SS.

Abstract: Systems, methods, and instrumentalities are disclosed that may be associated with HARQ-ACK codebook adaptations. A WTRU) may be configured with multiple physical uplink channels, e.g., physical uplink control channels (PUCCHs), in a slot. Each physical uplink channel may have a respective HARQ-ACK codebook. In examples, the WTRU may determine that a first physical uplink channel and a second physical uplink channel overlap in a slot. In such a case, the WTRU may determine that a first HARQ-ACK codebook associated with the first physical uplink channel has a higher priority than a second HARQ-ACK codebook associated with the second physical uplink channel. The WTRU may transmit the first HARQ-ACK codebook on the first physical uplink channel in the slot. The WTRU may send part of the second HARQ-ACK codebook in the slot and part of the second HARQ-ACK codebook in a subsequent slot (e.g., a next slot, a future slot, etc.).

Abstract: Systems, methods, and instrumentalities are disclosed for interleaving coded bits. A wireless transmit/receive unit (WTRU) may generate a plurality of polar encoded bits using polar encoding. The WTRU may divide the plurality of polar encoded bits into sub-blocks of equal size in a sequential manner. The WTRU may apply sub-block wise interleaving to the sub-blocks using an interleaver pattern. The sub-blocks associated with a subset of the sub-blocks may be interleaved, and sub-blocks associated with another subset of the sub-blocks may not be interleaved. The sub-block wise interleaving may include applying interleaving across the sub-blocks without interleaving bits associated with each of the sub-blocks. The WTRU may concatenate bits from each of the interleaved sub-blocks to generate interleaved bits, and store the interleaved bits associated with the interleaved sub-blocks in a circular buffer. The WTRU may select a plurality of bits for transmission from the interleaved bits.

Abstract: A wireless transmit/receive unit (WTRU) may measure one or more of a first plurality of beam reference signals. Further, the WTRU may select a first beam reference signal from among the measured one or more of the first plurality of beam reference signals. Also, WTRU may determine a set of physical random access channel (PRACH) resources for the selected first beam reference signal. Moreover, the WTRU may measure one or more of a second plurality of beam reference signals. Further, the WTRU may select a second beam reference signal from among the measured one or more of the second plurality of beam reference signals.

Abstract: A method performed by a WTRU may comprise generating a polar factor graph and pruning the polar factor graph to generate a pruned factor graph. The pruned factor graph may include input variable nodes, check nodes and output variable nodes. The method may further comprise the initializing input variable nodes. For each of a plurality of encoding levels of the pruned factor graph, values from the input variable nodes may be transferred to the check nodes. Operations, for example, XOR) additions, may be performed on the values of the check nodes. Check nodes having a single connection to another node not used in a previous transfer may be identified. Values from the identified check nodes may be transferred to the input variable nodes. Binary values from the input variable nodes may be transferred to the output variable nodes for transmission to a receiver.

Abstract: A wireless transmit/receive unit (WTRU) may transmit a preamble using a physical random access channel (PRACH) and determine a location of a random access response (RAR) based on a parameter of the PRACH. The location may include a subframe and/or a frequency resource on which the RAR is transmitted. The RAR may be received at the location. A device may receive a preamble using a PRACH associated with a coverage enhancement (CE) level and/or a CE mode of a WTRU. The device may determine a location of an RAR based on a parameter of the PRACH. The location may include a subframe and/or a frequency resource on which the RAR is to be transmitted. The device may determine a number of repetitions of the RAR to transmit based on the CE level or CE mode. The RAR may be transmitted at the location with the determined number of repetitions.

Abstract: Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) autonomously synchronizing. For example, a WTRU may be configured to receive a downlink timing synchronization. The WTRU may be configured to determine a synchronization signal. The WTRU may be configured to determine a synchronization mode. The synchronization mode may be RRC CONNECTED mode. The synchronization mode may be RRC IDLE mode. The WTRU may communicate data to the network while in an unsynchronized state in an RRC IDLE and/or an RRC CONNECTED mode. The communication of data while unsynchronized may reduce latency relative to one or more of a random access channel (RACH) procedure, a resource radio control (RRC) connection establishment procedure, or a data packet scheduling, for example.

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.
