  • Publication number: 20240057083
    Abstract: Systems and methods provide channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A UE may determine the DMRS for the PDSCH transmission with frequency hopping, and measure the DMRS for the PDSCH transmission to determine a CSI measurement. The UE may then report the CSI measurement to a base station.

  • Publication number: 20240057002
    Abstract: Apparatus and methods are provided to enhance communications for NTN. In some aspects, a base station (BS) comprises a processor configured to schedule an uplink transmission in response to an uplink transmission request from a user equipment (UE) using one or more subframes ranging from a first uplink subframe to a last uplink subframe. The processor is further configured to determine or receive a timing advance (TA) indicating amount of subframes transmitted during a time delay between the UE and the BS and schedule a downlink transmission aligned with the uplink transmission. The downlink transmission is blocked from subframes ranging from TA plus one or more subframes ahead of the first uplink subframe to TA minus one or more subframes ahead of the last uplink subframe. The processor is further configured to transmit and receive, via a non-terrestrial equipment, the uplink and the downlink.

  • Publication number: 20240057134
    Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network to correlate resource selection with shared spectrum channel access. The device can perform a resource selection procedures within a resource selection window (RSW) to determine a set of candidate resources, and a clear channel assessment (CCA). A resource selection of one or more resources can be performed from the set of candidate resources to enable a sidelink (SL) communication. The CCA initiates after an aperiodic traffic arrival, after a previous transmission, or after the resource selection is completed.

  • Publication number: 20240057137
    Abstract: Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values Preserve,rs-ev (and optionally period definition data Kre-ev). Restrictions on the use of random resource selection by the UE are also described.

  • Publication number: 20240057012
    Abstract: Apparatuses, systems, and methods for positioning reference signals (PRSs) for reduced capacity devices, e.g., in 5G NR systems and beyond. A UE may report, to a network one or more capabilities associated with a positioning procedure for location estimation.

  • Publication number: 20240057071
    Abstract: Some aspects include an apparatus, method, and computer program product for identifying a panel on user equipment (UE) for sounding reference signal (SRS) and/or physical uplink shared channel (PUSCH) communications. This panel selection may be applicable to codebook as well as non-codebook based PUSCH transmission schemes. In some aspects, a base station may provide the UE with an indication of one or more SRS resources and/or sets of SRS resources. The UE may then identify a panel corresponding to the indicated SRS resources and use this panel for PUSCH communications. In some aspects, the UE may apply prioritization scheduling when the UE uses different panels for SRS and PUSCH communications. This prioritization scheduling may address switching delays, which may occur when the UE switches between panels.

    Abstract: Apparatus and methods are provided for CSI enhancement for multi-TRP coherent joint transmission. A user equipment (UE) receives signals from a plurality of transmission and reception points (TRPs). The UE determines, based on the signals, multiple TRP (multi-TRP) coherent joint transmission (CJT) channel state information (CSI) report information for a codebook based on a spatial basis selection matrix, a combination coefficient matrix, and a frequency basis selection matrix. The spatial basis selection matrix is layer common, polarization common, and TRP independent. The UE reports, to one or more of the plurality of TRPs, the multi-TRP CJT CSI report information.

  • Patent number: 11902937
    Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

  • Publication number: 20240048288
    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to multiplex a first HARQ of a first priority and a second HARQ of a second priority to form an initial UCI payload. The UE can select a PUCCH resource accordingly to a PUCCH configuration, and generate a second UCI payload by removing or replacing at least a portion of the initial UCI payload when a size of the initial UCI payload is larger than a size of the PUCCH resource. The UE can encode at least a part of the second UCI payload including the first HARQ to generate an error correction code word. Afterwards, the UE can add the error correction code word to the second UCI payload to generate a transmission UCI payload, and transmit the transmission UCI payload to the base station.
