Abstract: A WTRU may select sidelink unicast or groupcast to transmit data. If the WTRU selects sidelink unicast, the WTRU may select to use HARQ ACK/NACK feedback for the transmission. If the WTRU selects sidelink groupcast, either HARQ NACK or HARQ ACK/NACK may be selected depending upon one or more factors. The WTRU may select HARQ NACK or HARQ ACK/NACK depending upon one or more of: a number of WTRUs to receive the data; a condition of a channel associated with transmission; or a quality of service associated with transmission. The WTRU may select a first or second PSFCH format for feedback based upon one or more factors. The WTRU may select a first or second PSFCH format based upon one or more of: the selected sidelink unicast or groupcast; the selected HARQ NACK or HARQ ACK/NACK feedback; or a quality of service associated with the transmission.

Abstract: Methods, systems, and. devices may assist in new radio (NR) sidelink (SL) operation in licensed or unlicensed spectrum. In an example, if listen-before-talk (LBT) failure rate is low, then implicit acknowledgement (ACK) and explicit non-acknowledgement (NACK) may be used. A first SL timer may start when a. SL transport block is transmitted. If no explicit NACK, is received before the SL timer expires, then ACK. may be assumed. If LBT failure rate is high, then explicit ACK and implicit NACK may be used. A second SL timer may start. If no explicit ACK is received before the SL timer expires, then NACK may be assumed.

Abstract: A method may comprise receiving a first signal comprising first LDPC bits including systematic bits and parity bits and transmitting information indicating that the first signal was incorrectly received. A second signal comprising second LDPC bits may be received in response to the transmitting. The second signal may include LDPC bits according to a lifting size of an LDPC base graph.

Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

Abstract: Systems, procedures, and instrumentalities are disclosed for synchronizing a signal burst, signal design, and/or system frame acquisition. A synchronization signal (SS) block or burst may be received. The SS block or burst may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and/or a Physical Broadcast Channel (PBCH). A first cell ID may be determined and/or a plurality of SSS sequences may be generated. An m0 value (e.g., a first cyclic shift) may be determined from a set of m0 values, for example, based on the generated plurality of SSS sequences. An n1 value (e.g., a second cyclic shift) may be determined from a set of n1 values. A second cell ID may be determined, for example, based on the m0 value and the n1 value. A third cell ID may be determined, for example, based on the second cell ID and the first cell ID.

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: 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: An apparatus and method for synchronization between a WTRU and a gNB are disclosed. The WTRU may receive a multiple beam synchronization signal from the gNB during synchronization. For each beam received by the WTRU, of the multiple beam synchronization signal, the WTRU may compare a received energy of the beam against a first threshold. A multiple beam synchronization signal may include a first and second synchronization signal (SS). If one or more beams of the multiple beam synchronization signal meets or exceeds the first threshold, the WTRU may report an indication of pre-synchronization to the gNB. This pre-synchronization may indicate to the gNB that a WTRU exists in an area of a particular beam of the WTRU. In this way, a gNB may target the WTRU using transmissions directed towards the WTRU.
