Patent №: 12143607 (November 12, 2024) – Method and apparatus for signalling flags related to chroma transform blocks.

A method is described for processing a bitstream containing syntax for transform and coding units. The transform unit syntax includes flags indicating if specific chroma transform blocks within the current transform unit contain any non-zero transform coefficients. The coding unit syntax includes a flag indicating the presence of a transform tree structure. Based on these flags, a fourth flag is derived to indicate if the luma transform block has any non-zero coefficients.

Patent №: 12144056 (November 12, 2024) – Sidelink DRX optimizations for RRC_Connected user equipment (UE). This disclosure describes SL-DRX enhancements for a UE in RRC_CONNECTED mode, utilizing both Uu and PC5 interfaces. These enhancements aim to trigger SL-DRX and share configurations, including optional alignment of SL-DRX with Uu-DRX (referred to as Uu/SL DRX alignment).

Patent №: 12144048 (November 12, 2024) – Secondary cell link recovery request transmission. Embodiments presented describe apparatuses, systems, and methods for a user equipment device (UE) to indicate a link failure on a secondary cell. This indication is sent on resources chosen based on specific conditions, with priority rules applied to resolve collisions. Following the link failure, the UE may assume a beam for continued communication with the secondary cell until receiving a network-selected beam.

Patent №: 12144023 (November 12, 2024) – Configuring listen before talk and short control signaling in unlicensed spectrum. A wireless device establishes a link with a cellular base station on an unlicensed cell, receiving configurations for listen-before-talk and short control signaling. When enabled, the device performs short control signaling with the base station, which may include uplink and/or downlink transmissions.

Patent №: 12143988 (November 12, 2024) – Systems and methods for QCL-typed collision handling. A UE may encounter a Quasi co-location TypeD (QCL-TypeD) collision when receiving multiple signals. To resolve this, the UE can select one of the signals based on the transmission scheme type associated with each signal. Selection options may include a priority rule for signal reception, a scheduling restriction, or a priority rule for QCL-TypeD selection.

Patent №: 12143987 (November 12, 2024) – Blind retransmission schemes. In one example, a method involves processing control information that specifies resources for a physical downlink or uplink shared channel (PDSCH/PUSCH) transmission and timing for its retransmission. The method includes configuring the device to receive the initial PDSCH/PUSCH, and, upon detecting a subsequent PDSCH/PUSCH at the specified retransmission time, combine it with the initial transmission in a HARQ buffer for decoding.

Patent №: 12143978 (November 12, 2024) – PDCCH enhancement for group paging. This disclosure describes methods for enhanced PDCCH group-based paging. A user equipment (UE) receives a paging indication via a PG-RNTI or at least six bits in a DCI, identifying a set of UEs. Each bit may indicate a paging message for specific UE subsets. If a paging message is intended for the UE, it decodes the corresponding PDSCH.

Patent №: 12143334 (November 12, 2024) – Configuring and providing physical downlink control channel communications with improved reliability. A base station establishes a link with a wireless device, providing configuration information for control resources associated with multiple transmission points in the device’s search space. The base station then delivers downlink control information using these configured control resources.

Patent №: 12143325 (November 12, 2024) – Quasi co-located framework for beam reception in a single frequency network. In a single frequency network (SFN), user equipment (UE) may receive one or more transmission configuration indication (TCI) states for downlink resources and a demodulated reference signal (DMRS) that is quasi co-located (QCLed) with channel state information reference signals (CSI-RS) from multiple SFN cells. The UE uses the CSI-RS to determine time and frequency offsets for each cell.

Patent №: 12143255 (November 12, 2024) – Subcarrier spacing restriction for SSB, CSI-RS for L3 mobility, and PDCCH/PDSCH. This technology allows a user equipment (UE) to indicate if it supports mixed numerology with different subcarrier spacings (SCS) for concurrent intra-frequency measurements and downlink data reception. Based on this indication, the network may adjust measurement and scheduling configurations for the UE.

Patent №: 12143191 (November 12, 2024) – Systems and methods for uplink codebook based transmission. This disclosure provides precoders for multi-panel uplink (UL) transmission, allowing separate NR and LTE transmissions across a UE’s antenna panels. Enhanced SRS supports multi-panel use, with the UE signaling its capability and determining UL precoders based on polarization and antenna co-phasing factors. The UE then transmits UL signals via these precoders.

Patent №: 12143186 (November 12, 2024) – Systems and methods for providing network indications for selecting asymmetric uplink (UL) antenna panels at user equipment (UE).  This method involves a base station receiving antenna capability info and an initial panel index from a user device, sending configuration for each panel, selecting the initial panel’s configuration, and receiving an uplink transmission. Alternatively, configurations may be sent as each panel is selected by the user device.

Patent №: 12138144 (November 12, 2024) – Patterned apertured webs.

This disclosure describes a patterned apertured web with land areas and apertures. Some land areas surround certain apertures, and the web has an Effective Open Area of about 3% to 30%. It also features varying Interaperture Distances with a specific median and mean. The apertures include two sets with different shapes.
