  • Publication number: 20240121058
    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 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.

  • Publication number: 20240121823
    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).

  • Patent number: 11956113
    Abstract: Methods and an apparatus for performing synchronization in New Radio (NR) systems are disclosed. A frequency band may be determined and may correspond to a WTRU. On a condition that the operational frequency band is a lower frequency, a synchronization signal block (SSB) index may be implicitly. On a condition that the operational frequency band is a higher frequency, an SSB index may be determined based on a hybrid method which includes determining the SSB index using both an implicit and an explicit method. A configuration of actually transmitted SSBs may be determined using a multi-level two stage compressed indication where SSB groups are determined based on a coarse indicator and actually transmitted SSBs with the SSB groups are determined based on a fine indicator.

  • Patent number: 11943724
    Abstract: A method and apparatus are disclosed for demodulating a NR-PBCH signal. The method may comprise receiving a primary SS and an SSS. The received SSS signal may be used as a reference signal to detect demodulation reference signals of the NR-PBCH. These demodulation reference signals may be interleaved with data on the NR-PBCH. In one method, the NR-PBCH DMRS are associated with an SSB index in an effort to improve randomization in the synchronization process. The NR-PBCH payload may be demodulated using the PSS and/or SSS and the DMRS. In one embodiment, the NR-PBCH DMRS may mapped to DMRS REs on a frequency first and time second mapping basis.
