  • Publication number: 20240192304
    Abstract: A wireless transmit/receive unit (WTRU) and a method are described herein regarding preservation of positioning integrity associated with wireless systems. Using multiple positioning configurations and/or schemes (e.g., positioning reference signal (PRS) configurations/schemes), e.g., based on a switching pattern, may ensure integrity (e.g., adequate and/or robust integrity), for example, if error events (e.g., low reference signal received power, blockage of PRS from transmission/reception points (TRPs), etc.) have a persistent duration.

  • Publication number: 20240187903
    Abstract: The disclosure pertains to methods and apparatus for performing positioning of wireless transmit and/or receive units (WTRUs) in wireless communication systems. A WTRU may receive configuration information indicating a time window associated with positioning. The configuration information may indicate any of a duration and a periodicity of the time window. The WTRU may receive (1) first scheduling information indicating to transmit a first uplink transmission including a sounding reference signal (SRS) and (2) second scheduling information indicating to transmit a second uplink transmission including a positioning SRS (SRSp). The first uplink transmission may not include any SRSp. On condition that the second uplink transmission is scheduled for transmission during the time window, the WTRU may transmit the second uplink transmission during the time window and may transmit the first uplink transmission only when the first uplink transmission is scheduled for transmission outside of the time window.

  • Publication number: 20240187160
    Abstract: In one or more embodiments, there may be one or more devices, methods, and/or systems addressing or relating to carrier switching for sending uplink control information. In one case, a wireless transmit receive unit (WTRU) may have more than one uplink channel carrier available.

  • Publication number: 20240107549
    Abstract: A wireless transmit/receive unit (WTRU) determines PDCCH candidates. For a slot, the WTRU determines a number of valid PDCCH candidates associated with at least one search space based on a number of designated search spaces associated with the WTRU in the slot, a type of the search space, a priority associated with the search space, a number of required CCE channel estimates associated with the search space, a maximum number of PDCCH candidates in a slot, and a number of control resource sets (CORESETs) associated with the slot. The WTRU may then attempt to decode CCEs in the at least one search space to recover a PDCCH associated with the WTRU. The WTRU may drop PDCCH candidates from the search space when the number of PDCCH exceeds a maximum value.

  • Publication number: 20240080806
    Abstract: Methods and apparatuses are described herein for sidelink communication in a wireless transmit/receive unit (WTRU). For example, a first WTRU configured with first and second resource pools may perform at least one congestion measurement of the second resource pool. The first resource pool may be configured for use by the first WTRU for transmission of the first data. The second resource pool may be configured for use by a second WTRU for transmission of the second data associated with a higher priority than the first data. If the at least one congestion measurement of the second resource pool is below a predetermined threshold, the first WTRU may transmit the first data using the first resource pool. If the at least one congestion measurement of the second resource pool is above a predetermined threshold, the first US may not transmit the first data using the first resource pool.

  • Publication number: 20230388931
    Abstract: A wireless transmit/receive unit (WTRU) may receive/transmit data by employing a discontinuous reception cycle, which may include an awake state and a sleep state. For example, while in an awake state, a WTRU may monitor a PDCCH for a subset of time instances. During the remaining time instances, the WTRU may enter a sleep state, in which the WTRU may switch its receiving circuitry off (e.g., to reduce power consumption). A WTRU may receive (e.g., may expect to receive) one or more transmissions, during an awake state, before entering a sleep state. The durations of an awake state and/or the durations of subsequent sleep states may be determined based on whether the WTRU receives a transmission during the awake state and/or what the transmission was for. The WTRU may modify the value of a sleep state timer based on previous sleep state and/or awake state timer values.

  • Publication number: 20230354327
    Abstract: A wireless transmit receive unit (WTRU) may be configured to monitor physical downlink control channel (PDCCH) candidates of a primary cell (PCell) and a secondary cell (SCell). The WTRU may be configured to determine a time duration for PDCCH candidate budgets for a set of symbols based on a subcarrier spacing associated with the PCell and a subcarrier spacing associated with the SCell. The WTRU may be configured to determine a maximum number of PDCCH candidates to allocate to a search space monitoring occasion of the PCell and the SCell. The maximum number of PDCCH candidates may be based on a per-cell ratio. The WTRU may be configured to allocate PDCCH candidates for the search space monitoring occasion of the PCell and the search space monitoring occasion of the SCell based on the determined maximum number of PDCCH candidates. The WTRU may be configured to decode an allocated PDCCH candidate.
