Abstract: A wireless transmit/receive unit (WTRU) may receive a first signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The PSS and SSS may be received in a resource block of a cell and the resource block may have a first numerology. Further, the first numerology may have a first subcarrier spacing, while other resources of the cell at a same time as the resource block may have a second numerology with a different subcarrier spacing than the first numerology. In addition, the WTRU may determine synchronization based on the PSS and SSS. Also, the WTRU may receive a second signal in the cell, and the second signal may have the second numerology. Moreover, the WTRU may transmit user data. In a further example, the WTRU may search a frequency raster for the PSS and the SSS.

Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information indicating a set of physical channel frequency resources. The WTRU may receive downlink control information (DCI), and the DCI may include an indication of an allocation of at least a subset of the set of physical channel frequency resources. Further, the WTRU may determine a time period and one or more physical channel frequency resources from the subset of the set of physical channel frequency resources. The WTRU may transmit control information in a physical shared channel transmission using the determined one or more physical shared channel frequency resources during the determined time period. Also, the control information may include a WTRU-identifier (ID) associated with the WTRU. In an example, the control information may include a new data indicator (NDI) or a retransmission of previously transmitted control information. In a further example, the physical shared channel transmission may further include data.

Abstract: Methods and apparatuses are described herein for providing a single-bit hybrid automatic repeat request (HARQ) feedback and a multi-bit HARQ feedback in a wireless transmit/receive unit (WTRU). For example, a WTRU may receive, via a physical downlink control channel (PDCCH), downlink control information (DCI). The DCI may include a field that indicates a code block group (CBG) based retransmission for at least one transport block (TB). On a condition that the DCI does not include the field, the WTRU may transmit, via a physical uplink control channel (PUCCH), a single-bit HARQ feedback for a TB-based retransmission. On a condition that the DCI includes the field, the WTRU may transmit, via the PUCCH, the multi-bit HARQ feedback for the CBG-based retransmission. The WTRU may be configured to provide the single-bit HARQ feedback for the TB-based retransmission and a multi-bit HARQ feedback for the CBG-based retransmission.

Abstract: Methods, apparatuses and systems are provided for grant-less (GL) uplink transmissions. A wireless transmit/receive unit (WTRU) may receive a configuration of a set of GL Physical Uplink Shared Channel (GL-PUSCH) frequency resources. The WTRU may monitor for a downlink control information (DCI) message, wherein the DCI message includes an indication of a presence of at least a subset of the set of GL-PUSCH frequency resources. If the WTRU successfully receives the DCI message, the WTRU may select one or more GL-PUSCH frequency resources from the subset of the set of GL-PUSCH frequency resources and may select a time period. The WTRU may transmit data on a GL-PUSCH using the selected GL-PUSCH frequency resources during the selected time period. The WTRU may also monitor for hybrid automatic repeat request acknowledgement (HARQ-ACK) based on the selected GL-PUSCH frequency resources. The WTRU may monitor for the DCI during a fixed time window.

Abstract: Techniques may be used to generate a multi-length Zero Tail (ZT) Discrete Fourier Transform-spread Orthogonal Frequency Domain Modulation (DFT-s-OFDM) signal for transmission. A selected allocation of frequency resources may include a plurality of subbands. Subbands may be assigned to wireless transmit/receive units (WTRUs) (i.e., users), and zero head length and zero tail length may be assigned to each of the assigned subbands according to a pattern to combat inter-symbol interference (ISI). The ZT DFT-s OFDM signal may generated for transmission over the assigned subbands in accordance with the assigned zero head length and the assigned zero tail length.

Abstract: Methods, apparatus, and systems are disclosed. In one embodiment, a method of reporting Channel State Information (CSI) by a wireless transmit/receive unit (WTRU) includes receiving configuration information indicating a plurality of CSI reporting configurations and information indicating multiple downlink (DL) semi-persistent scheduling (SPS) resource configurations, wherein each indicated DL SPS resource configuration is associated with a CSI reporting configuration; and receiving an indicator indicating which one or more of the multiple DL SPS resource configurations are active. The method further includes determining one or more measurement time/frequency resources based on a respective CSI reporting configuration or respective CSI reporting configurations associated with the one or more active DL SPS resource configurations; performing one or more measurements on the determined measurement time/frequency resources; and reporting CSI, wherein the CSI is based on the one or more measurements.

Abstract: A wireless transmit/receive unit (WTRU) 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. The WTRU may then transmit the first set of bits in the first codeword at a first allocated power and the second set of bits in the first codeword at a second allocated power. In an example, the second allocated power may be great than the first allocated power. Further, the WTRU may determine the second allocated power based on power boosting the first allocated power. In another example, the WTRU may receive an assignment message from a base station including instructions regarding partition determination and resource assignment. The WTRU may then determine at least two partitions of bandwidth based on the assignment message. Further, each partition may have differing symbol periods, differing subcarrier spacing or both.

Abstract: Methods, devices, and systems for transmitting information using a unique word (UW) with discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) are described herein. In an example, a wireless transmit/receive unit (WTRU) may generate a reference sequence. Further, the WTRU may generate a DMRS sequence based on upsampling of the reference sequence. In an example, the DMRS sequence may include a plurality of repeating sequences. Further, in an example, each repeating sequence may include a head sequence, a reference sequences and a tail sequence. Also, a UW sequence within the DMRS may include one of the repeated head sequences and one of the repeated tail sequences. In addition, the WTRU may generate a DMRS signal based on a waveform operation on the DMRS sequence. The WTRU may then transmit the DMRS signal as a reference signal.
