  • Publication number: 20260173023
    Abstract: Methods, apparatuses, systems, etc., directed to performing positioning of a wireless transmit/receive unit (WTRU) while it is in idle mode and/or inactive mode (collectively “idle/inactive mode”) in NR are disclosed herein. Performing positioning, including positioning measurement and/or reporting, in idle/inactive mode may allow for increased positioning accuracy and/or decreased latency of location determination. In various embodiments, a WTRU in idle/inactive mode may transmit a positioning measurement report in various ways, including (i) in a Random-Access Channel (RACH) preamble; (ii) appended to a RACH preamble; and/or (iii) in a Physical Uplink Shared Channel. In various embodiments, a WTRU in idle/inactive mode may transmit uplink-based positioning related reference signals. In various embodiments, a WTRU in an idle/inactive mode may transmit, over a dedicated physical channel, (e.g., downlink) positioning measurement reports and/or reference signals (RSs) for uplink positioning measurements.

  • Patent number: 12615665
    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: 20260067909
    Abstract: Described herein are solutions for dynamic sidelink (SL) autonomous channel selection access. A user equipment (UE) can initiate a sensing window based on a prediction of transport block (TB) generation. A SL-capable UE operating in mode 2 can predict an arrival of a TB in a buffer of the UE and can initiate monitoring of the channel for a configured duration before the predicted arrival of the TB. A sensing and selection window size can be adapted based on traffic quality of service (QoS). The UE can dynamically adapt the sensing and selection windows based on a predicted priority or QoS of the future TBs. These and many other features and examples are described herein.

  • Publication number: 20260046939
    Abstract: Systems, devices and methods for a backscatter measurement based multiple RACH preamble transmissions are disclosed. A WTRU may receive a JCS-RS configuration comprising a minimum RACH preamble retransmission interval. The JCS-RS configuration may comprise a JCS backscatter power fraction (?) of the WTRU transmit power (PTx). The WTRU may transmit a RACH preamble in a RACH occasion corresponding to a preferred SS/PBCH Index using an initial WTRU transmit beam, having an associated first RA-RNTI value. The backscatter power (PBS) may be measured using the WTRU receive beam corresponding to the WTRU transmit beam used for the RACH preamble transmission. On a condition that PBS>?PTX, the WTRU may retransmit the RACH preamble after a retransmission interval, on resources associated with a second RA-RNTI value. The WTRU may be configured for monitoring the PDCCH common search space with the first RA-RNTI and the second RA-RNTI, for respective RAR window intervals.

  • Patent number: 12538204
    Abstract: An Integrated Access and Backhaul, IAB, node determines link degradation in a primary path to a first Distributed Unit, DU, of a gNB, establishes a secondary path with a second DU of a gNB, detects link failure in the primary path, releases the primary path and makes the second primary path as a new primary path. A first IAB donor node receives an indication of link degradation from an IAB node in a network managed by the first IAB donor node, determines that an available IAB node is in a network managed by a second IAB donor node, sends to the second IAB donor node a request to connect the IAB node with the second IAB donor node and, in case the request is accepted, requests the IAB node to connect with the second IAB donor node.

  • Publication number: 20250386191
    Abstract: This Application describes managing access to a Citizens Band Radio Service (CBRS) private wireless network that is maintained by a CBRS wireless network hub. A CBRS wireless node associates with the CBRS wireless network hub and obtains an electronic subscriber identity module (eSIM) to connect to the CBRS private wireless network. The eSIM is generated by the CBRS wireless network hub or by a cloud-network server using a one-time public key (otPK) obtained from the CBRS wireless node. The CBRS wireless node can authenticate before obtaining the eSIM based on i) having a common cloud-network service account or a different cloud-network service account of the cloud-network server as the CBRS wireless network hub, or ii) by using a mutual authentication procedure. The eSIM can be revoked and stored at the CBRS wireless network hub for subsequent re-use with the CBRS wireless node.

For example, an example of a process for transferring ownership of an at least partially obfuscated NFT can include at least partially encrypting an NFT. The process can further include associating the at least partially obfuscated NFT with a smart contract that defines conditions under which the at least partially obfuscated NFT will be transferred to a buyer with a decryption key to decrypt the at least partially obfuscated NFT. The conditions ensure that a clear portion of the at least partially obfuscated NFT is part of the at least partially obfuscated NFT. The process includes receiving a request from a buyer to purchase the at least partially obfuscated NFT. Further, the process can include executing, based on receiving the request, the smart contract to complete the transaction based on the conditions of the smart contract.
