    Abstract: Apparatuses and methods are disclosed for panel selection for uplink (UL) transmission in a multi-transmission-reception point (TRP) system. A method performed by a wireless transmit/receive unit (WTRU) may include receiving, for each of a plurality of transmit/receive points (TRPs), information for measuring a first set of reference signals and spatial relation information, the spatial relation information associating each of one or more transmit beams with one or more of a second set of reference signals and with physical uplink control channel (PUCCH) resources. The method may include, for each of the plurality of TRPs, measuring a pathloss of each common reference signal among the first and second set of reference signals. The method may include selecting a transmit beam and a TRP and sending a transmission to the selected TRP. The transmit beam may be associated with an antenna panel of the WTRU.

    Abstract: A wireless transmit/receive unit (WTRU) may receive a PDCCH transmission comprising a CCE that is mapped to one or more REGs based on a CCE-to-REG mapping. The WTRU may receive the CCE-to-REG mapping that indicates a REG bundle corresponding to the CCE and use the CCE-to-REG mapping to identify the REGs for the WTRU. Depending on whether the CCE-to-REG mapping is interleaving or noninterleaving, the CCE-to-REG mapping may be based on different parameters. If the CCE-to-REG mapping is interleaving, the CCE-to-REG mapping may be based on an index associated with the CCE and a number of REGs in the REG bundle. If the CCE-to-REG mapping is noninterleaving, the CCE-to-REG mapping may be based on the index of the CCE.

    Abstract: A system, method, and device for ensuring a number of Phase Tracking Reference Signal(s) (PT-RSs) are the same for multiple slots. A wireless transmit/receive unit (WTRU) may receive control information including a number of scheduled resource blocks (RBs) then determine a PT-RS density based on the number of scheduled RBs. The WTRU may determine a RB offset value for the WTRU based on a WTRU-ID modulo the maximum RB offset value, where the maximum value for the RB offset value may be based on at least one of the number of the scheduled RBs and the PT-RS density. The WTRU may then transmit or receive a signal with PT-RS based on the RB offset value.

    Abstract: A wireless transmit/receive unit (WTRU) may receive a PDCCH transmission comprising a CCE that is mapped to one or more REGs based on a CCE-to-REG mapping. The WTRU may receive the CCE-to-REG mapping that indicates a REG bundle corresponding to the CCE and use the CCE-to-REG mapping to identify the REGs for the SWTRU. Depending on whether the CCE-to-REG mapping is interleaving or noninterleaving, the CCE-to-REG mapping may be based on different parameters. If the CCE-to-REG mapping is interleaving, the CCE-to-REG mapping may be based on an index associated with the CCE and a number of REGs in the REG bundle. If the CCE-to-REG mapping is noninterleaving, the CCE-to-REG mapping may be based on the index of the CCE.

    Abstract: Systems, methods, and instrumentalities are disclosed for physical (PHY) layer multiplexing of different types of traffic in 5G systems. A device may receive a communication. The communication may include a first traffic type. The device may monitor the communication for an indication that the communication includes a second traffic type that is multiplexed with and/or punctures the first traffic type. An indicator received in the communication and detected by the monitoring may indicate where the second traffic type is located in the communication. The first traffic type and the second traffic type may be multiplexed at a resource element (RE) level. For example, a first traffic type may be punctured by a second traffic type at the RE level. The device may decode one or more of the first or second traffic types in the communication based on the indication.

    IPC: H04B7/06

    Abstract: Hybrid beamforming may be configured for wireless communication systems (e.g., multiple-input multiple output (MIMO) and/or massive-MIMO). The implementation(s) may determine a number of radio frequency (RF) chains for realizing a fully digital precoder (FDP) in a structure (e.g., a hybrid analog/digital precoder). The number of RF chains may be less than a number of transmitter antennas. A transmit vector signal may be determined based on a digital precoder and an input symbol vector. An analog precoder and/or a baseband signal may be determined based on the determined transmit vector signal. The number of RF chains may be determined based on the determined baseband signal. The baseband signal may be fed to the determined number of RF chains. The analog precoder may determine a beamforming signal based on an output of the determined number of RF chains. The analog precoder may transmit the beamforming signal using the number of transmitter antennas.

    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.
