  • Patent number: 11569885
    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.

  • Publication number: 20230015536
    Abstract: A method to reserve a directional channel, such as in an unlicensed spectrum for instance, is disclosed. In an example embodiment, the method may be performed by a receiving node, such as a user equipment (UE) for instance. In such method, the receiving node may receive an enhanced directional transmit request message from a transmitting node and transmit an enhanced directional transmit confirmation message using one or more first beams, with at least one first beam being directed in a first direction towards the transmitting node. Further, the receiving node may transmit at least one additional enhanced directional transmit confirmation message using one or more second beams, with at least one second beam being directed in a second direction towards a potentially interfering node. In the method, the second direction is a different direction than the first direction.

  • Publication number: 20230016295
    Abstract: Systems, methods, and instrumentalities are disclosed for LTE operation in an unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may establish a connection with a first cell on a licensed frequency band. The WTRU may receive a first downlink transmission from a second cell operating on an unlicensed frequency band. The WTRU may determine that a synchronization signal transmission from a third cell operating on the unlicensed frequency band is transmitted using one or more resource elements. The WTRU may perform frequency and/or timing estimation based on the synchronization signal transmission. The WTRU may perform rate matching around the one or more resource elements that correspond to the synchronization signal transmission. The WTRU may perform rate matching around the one or more resource elements by de-mapping symbols of the downlink transmission.

    Abstract: A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

  • Patent number: 11528112
    Abstract: A wireless transmit/receive unit (WTRU) is configured to determine a frequency location of a reduced frequency bandwidth within a full system frequency bandwidth for an uplink transmission. The reduced frequency bandwidth is based on a received MTC physical downlink control channel. The WTRU is configured to determine a frequency location of an uplink resource in a first subframe based on at least one of a subframe number of the first subframe, a transmission repetition number associated with the first subframe, or a coverage enhancement level of the WTRU. The WTRU is configured to send a physical uplink control channel (PUCCH) transmission in the uplink resource in the first subframe in a same frequency location in both slots of the first subframe. A format of the PUCCH transmission is limited to a subset of PUCCH formats available for a WTRU operating in the full system frequency bandwidth.

  • Publication number: 20220394672
    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: 20220394703
    Abstract: A wireless transmit/receive unit (WTRU) may receive downlink control information (DCI) including an uplink grant. The WTRU may determine available processing time based on the end of a time unit at the end of the DCI and the start of a time unit at the start of a transmission scheduled by the uplink grant. On a condition that the available processing time is at or above a threshold, the WTRU may transmit the transmission scheduled by the uplink grant. In an example, the wherein the time unit at the end of the DCI may be a first symbol and the time unit at the start of a transmission scheduled by the uplink grant may be a second symbol. Further, the transmission scheduled by the uplink grant may be a physical uplink shared channel (PUSCH). Also, the available processing time may include a timeline value indicated by the DCI.

  • Publication number: 20220386366
    Abstract: A wireless transmit receive unit (WTRU) may receive a set of candidate resources, which may be used for transmission. The WTRU may periodically perform CCA on a channel (e.g., before transmitting on the channel). When the channel is determined to be free, the WTRU may determine a resource for transmission from the candidate resources. The resource may be determined based on the time remaining in the time period. For example, when the time remaining in the time period is shorter, the WTRU may determine to transmit on a resource that comprises more frequency resources. The WTRU may determine a Multiple Input Multiple Output (MIMO) scheme based on the number of frequency resources. The WTRU may send a transmission on the resource, which may include a demodulation reference signal (DM-RS). The DM-RS may indicate the resource used from transmission to a receiver of the transmission.

  • Publication number: 20220368574
    Abstract: Systems, methods, and instrumentalities are disclosed for Uplink operation in LTE unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may receive licensed assisted access (LAA) configuration information, e.g., for a first cell from a second cell. The first cell may be associated with operation in an unlicensed band, and the second cell may be associated with operation in a licensed band. The WTRU may determine whether a first subframe is a sounding reference signal (SRS) subframe for the first cell. If the first subframe is an SRS subframe for the first cell, the WTRU may determine SRS resources for the first subframe and determine whether the WTRU is triggered to transmit an SRS transmission in the first subframe. If it is determined the WTRU is triggered to transmit the SRS transmission in the first subframe, the WTRU may transmit the SRS transmission on the SRS resources for the first subframe.
