    Abstract: A wireless transmit/receive unit (WTRU) may perform listen before talk (LBT) on a channel prior to uplink transmission on the channel. The WTRU may adjust an amount of time that the WTRU performs LBT. For example, WTRU may receive a set of transmission opportunities. The WTRU may receive a contention window size (CWS) sequence including a CWS for each transmission opportunity. The CWS sequence may be unique and may be based on the identity of the WTRU. For a given transmission opportunity, the WTRU may select a random number between zero and the CWS for that transmission opportunity. If the channel is clear for at least an amount of time associated with the random number, the WTRU may transmit in the transmission opportunity. If the channel is not clear for at least an amount of time associated with the random number, the WTRU may not transmit in the transmission opportunity.

    Abstract: Systems, methods and instrumentalities are disclosed for flexible SRS-based UL beam management. UL beam management may be assisted, for example, by DL beam management. In an example, a WTRU may determine a UL Tx beam based on a DL Rx beam for full beam correspondence (BC), a WTRU may engage in beam adjustment with data transmission for partial BC and a WTRU may, e.g., otherwise, transmit an SRS for UL beam sweeping. BC may be determined, for example, by a WTRU or a TRP. WTRU may provide the assist information to facilitate TRP SRS configuration. Flexible UL beam management may be provided, for example, by flexible SRS configuration of WTRUs depending on configured beam management procedures. Intra-symbol UL beam sweeping may be provided with frequency and time separations. SRS power setting may be provided for UL beam management.

    Abstract: Systems, methods, and instrumentalities are disclosed for non-orthogonal multiple access (NOMA), frequency hopping, and power control. NOMA may be applied to asynchronous and/or grant-free transmissions. Transmissions from multiple WTRUs may be performed using the same resources, and may comprise information for correctly identifying and decoding the transmissions. The transmissions may comprise a built-in deterministic sequence to support timing acquisition at a receiver. The transmissions may be distinguished based on respective transmit power used for the transmissions. Such transmit power may be dynamically controlled by applying a randomly selected power offset. The power control may be performed autonomously by a WTRU.

    Abstract: A wireless transmit/receive unit (WTRU) may modulate, based on a number of uplink control bits, a first sequence or the first sequence and a second sequence. The WTRU may spread the first sequence and the second sequence with a complementary sequence pair, concatenate parts of the first sequence and the second sequence in interlaced resource blocks (RBs), and perform an inverse discrete Fourier transform (IDFT) on the interlaced parts. The WTRU may transmit on a physical uplink control channel (PUCCH) a signal outputted by the IDFT.

    Abstract: A wireless transmit/receive unit (WTRU), using mixed numerologies, may, in a first codeword, map a first set of bits to a higher order modulation scheme and a second set of bits to a lower order scheme, and transmit the first codeword. The WTRU may determine that data of the first codeword is to be re-transmitted on a second codeword, containing the same number of bits as the first codeword. In the second codeword, the WTRU may map a first set of bits to the lower order scheme and a second set of bits to the higher order scheme. The first set of bits of the second codeword may contain the same number of bits as the second set of bits of the first codeword and may contain at least a subset of data in the first set of bits of the first codeword. The WTRU may transmit the second codeword.
