  • Publication number: 20210058207
    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.

  • Publication number: 20210058967
    Abstract: An LBT method and apparatus are disclosed for a WTRU and gNB. A method may comprise receiving a gNB beam direction schedule and an LBT measurement configuration. The WTRU may switch a receiver so as to receive a beam based on the beam direction schedule and monitor for a DCI. The WTRU may be configured to determine whether there is a transmission for the WTRU and if there is, the transmission may be received. The transmission may be a DCI for an uplink transmission of the WTRU. A WTRU may be configured to receive the gNB beam direction schedule and the LBT measurement configuration at a start of an MCOT.

  • Publication number: 20210037511
    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.

  • Publication number: 20200396698
    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.

  • Patent number: 10848232
    Abstract: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.

  • Patent number: 10827459
    Abstract: Methods and apparatuses are described herein for paging procedures in wireless systems. For example, a wireless transmit receive unit (WTRU) may monitor one or more physical downlink control channels (PDCCHs) for paging resources associated with a first subset of synchronization signal (SS) blocks that corresponds to a first beam tracking area (BTA). On a condition that at least one measurement of at least one beam associated with the first subset of SS blocks is less than a predetermined threshold, the WTRU may transmit, to a base station (BS), a signal indicating a second BTA that is associated with a second subset of SS blocks. The signal includes a physical random access channel (PRACH) resource associated with a second group of SS blocks that corresponds to the second BTA.

  • Publication number: 20200328855
    Abstract: Methods, systems and apparatus are provided for hybrid automatic repeat request (HARQ) processes. A wireless transmit/receive unit (WTRU) may receive, in a first subframe, downlink control information (DCI) including a grant for a physical downlink shared control channel (PDSCH) and an indication of physical uplink control channel (PUCCH) resources. Further, the WTRU may receive, in the first subframe, data on the PDSCH based on the grant. Also, the WTRU may generate first acknowledgement (ACK)/negative ACK (NACK) information based on the data received on the PDSCH. Accordingly, the WTRU may transmit, in the first subframe, the first ACK/NACK information in a PUCCH transmission. In an example, the first ACK/NACK information may be transmitted in a time slot in the first subframe different from a time slot in the first subframe in which the DCI is received. Also, transmitting the PUCCH transmission may have a duration of one or two symbols.
