  • 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: 11902929
    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: 11874812
    Abstract: A method, apparatus, and computer program product for executing a relational database management system (RDBMS) in a computer system, wherein the RDBMS manages a relational database comprised of at least one column-partitioned base table storing data. Column values from at least one column of the column-partitioned base table are stored in one or more containers spread across one or more data blocks. Metadata comprising summarized information about the column values in the containers is stored in a metadata index subtable. A query with a filtering condition on the column is applied to the metadata index subtable before the column-partitioned base table is accessed, so that only qualified containers and data blocks are accessed, and unqualified containers and data blocks are eliminated, when responding to the query.

  • Publication number: 20230397084
    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.

  • Patent number: 11736450
    Abstract: A method of facilitating an anonymous message board may include receiving a secret key share associated with a published public key. An initial table state may be generated by encrypting, via the public key, an initial table including a table index and table initial values. A user post encrypted via the public key may be received, the user post including a message and a message index value. The initial table state may be updated to an updated table state by replacing an initial table value of the initial table values with the message. In response to a time interval associated with a predetermined length of time expiring after generating the initial table state, the updated table state may be partially decrypted via the first secret key share as a partially decrypted table. The partially decrypted table may be broadcast.

  • Publication number: 20230254899
    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.
