  • Publication number: 20220022163
    Abstract: A method and apparatus are described for a low cost machine-type-communication (LC-MTC) wireless transmit/receive unit (WTRU) to enhance coverage. An example method for physical broadcast channel (PBCH) enhancement includes receiving system information on an enhanced PBCH (ePBCH). The ePBCH is located in a set of radio frames which is a subset of available radio frames, where the subset includes fewer than all the available radio frames. The ePBCH is received in at least one radio frame of the set of radio frames. An example method for physical random access channel (PRACH) enhancement includes receiving configuration of legacy PRACH resources and enhanced PRACH (ePRACH) resources. The WTRU selects one of legacy PRACH resources or ePRACH resources based on a coverage capability. Another example method for PRACH enhancement includes receiving configuration of ePRACH resources. The ePRACH resources include multiple ePRACH resource types, each ePRACH resource type being associated with a coverage capability.

  • Patent number: 11223394
    Abstract: Systems, methods, and instrumentalities are disclosed for antenna virtualization, e.g., in at least a two-dimensional antenna array. NE physical antenna elements may be virtualized to Np logical antenna ports. A virtualization may be WTRU-specific, which may optimize MIMO performance. A simplified MIMO scheme may be used with A reduction in feedback, reference signal, and/or control signaling overhead. Antenna virtualization schemes may utilize channel characteristics. Antenna virtualization may be defined, for example, based on antenna port to antenna element mapping, based on a measurement reference signal, based on a codebook or a codebook subset or based on an antenna virtualization matrix. One or more antenna virtualization schemes may be configured in a cell. Antenna virtualization schemes may be configured in a WTRU-specific manner, perhaps for example based on a WTRU channel characteristic(s). A WTRU may report one or more useful (e.g., optimized) antenna virtualization schemes, e.g.

  • Patent number: 11218253
    Abstract: Systems, methods, and instrumentalities are disclosed for narrowband (NB) LTE operation. A WTRU may receive a first downlink data transmission, for example, via a physical downlink shared channel (PDSCH). The WTRU may determine to send a hybrid automatic repeat request (HARQ) acknowledgment (ACK) in response to receipt of the first downlink data transmission. The WTRU may transmit a first uplink reference signal. The WTRU may indicate the HARQ-ACK using a first cyclic shift index that is applied to the first uplink reference signal. The WTRU may determine to send a HARQ negative ACK (HARQ-NACK), for example, on a condition that a second downlink data transmission is not correctly received. The WTRU may send a second uplink reference signal. The WTRU may indicate the HARQ-NACK using a second cyclic shift that is applied to the second uplink reference signal.

  • Publication number: 20210392681
    Abstract: Systems, devices, and methods for operating in an unlicensed band are disclosed herein. In one example, a device may receive configuration information that includes a maximum channel occupancy time (MCOT) and a plurality of parameters including a plurality of transmission opportunity windows (TOWs). Based on the configuration information, the device may split a transmission into a plurality of bursts that may be grouped into sets of bursts based on how many bursts fit within a TOW. The number of bursts in a set of bursts may be less than or equal to the MCOT. The device may perform a clear channel assessment (CCA) to determine if the channel is busy and to determine a start time within the TOW for the bursts. The device may then transmit the set of bursts for that TOW, where each burst may have a burst indicator (BI).

  • Publication number: 20210391909
    Abstract: Methods, apparatuses and systems are provided for transmission of a CSI report. A WTRU may receive an aperiodic CSI reporting request on a PDCCH. The WTRU may determine a time gap between a last symbol of the PDCCH of which the aperiodic CSI reporting request is received and a first uplink symbol of a designated uplink channel for transmission of a corresponding aperiodic CSI report. The determination of the time gap may include consideration of a timing advance value. A determination may be made as to whether a time threshold is shorter than the determined time gap. If the determined time gap is not shorter than the time threshold, the WTRU may transmit the CSI report. If the determined time gap is shorter than the threshold, the WTRU may not transmit the CSI report.

    Abstract: A wireless transmit/receive unit (WTRU) may receive a physical downlink control channel (PDCCH) transmission in a WTRU-specific search space, with the PDCCH transmission including a sequence scrambled based on a first radio network temporary identifier (RNTI), the first RNTI associated with the WTRU, and the sequence including downlink control information (DCI) and a cyclic redundancy check (CRC). The WTRU may determine scheduling information for a physical downlink shared channel (PDSCH) transmission based on the DCI. Further, the WTRU may receive the PDSCH based on the scrambling information. Additionally, the first RNTI may be a WTRU-identifier (WTRU-ID). Also, the DCI and CRC may be scrambled by a second RNTI. Moreover, the WTRU may receive scrambling indication information indicating that scrambling of information in a PDCCH transmission by an RNTI may be used. Also, the PDCCH transmission may include the sequence on a condition that the scrambling indication information is received.

  • Publication number: 20210321446
    Abstract: Methods and apparatus for wireless transmit/receive unit (WTRU) power control are described. A method includes receiving a time domain resource allocation (TDRA) list configuration including entries, each including a resource allocation that includes a slot offset value. L1 signaling is received indicating a minimum slot offset value. Downlink control information (DCI) is decoded on a physical downlink control channel in a slot. An index is obtained from the decoded DCI, identifying an entry in the TDRA list. A particular slot offset value identified by the index is retrieved from the TDRA list and compared with the minimum slot offset value. If the particular slot offset value is less than the minimum slot offset value, the entry is invalid. If the particular slot offset value is greater than or equal to the minimum slot offset value, a physical downlink shared channel is received.

  • Publication number: 20210314866
    Abstract: Systems, methods, and devices for addressing power savings signals in wireless communication. A wireless transmit receive unit (WTRU) may monitor for an energy saving signal (ESS) while the WTRU is asleep (e.g., prior to a discontinuous reception (DRX) ON duration that includes one or more search spaces). The WTRU may measure the energy of the ESS. If the ESS is below a threshold, the WTRU fallback to a default operation or continue in a current operating mode (e.g., remain asleep to save power). If the ESS is above a threshold, the ESS may be received using a coverage enhancement (CE) level based on a parameter associated with a search space. The parameter may be the highest aggregation level of the one or more search spaces.

  • Publication number: 20210297221
    Abstract: Devices and methods are disclosed for a physical sidelink control channel (PSCCH) design in new radio (NR). A wireless transmit receive unit (WTRU) for sidelink communication may receive a resource pool identity (ID). Further, the WTRU may determine whether to include information related to demodulation reference signal (DM-RS) density for a sidelink transmission in sidelink control information (SCI) based on the resource pool ID. On a condition that the information related to DM-RS density is to be included in the SCI, the WTRU may transmit the SCI including the information related to DM-RS density. Also, the SCI may be associated with a PSSCH. Accordingly, the WTRU may transmit the sidelink transmission on the PSSCH with one or more DM-RSs at a first DM-RS density based on the information related to DM-RS density.
