  • Publication number: 20220312395
    Abstract: Downlink Control Information (DCI) may be expanded, or enhanced, to allow nodes such as UEs, eNBs, NR-nodes, gNBs, and TRPs in M2M, IoT, WoT networks to coordinate activities on PHY, MAC, and RRC layers. For example, DCI fields may be added or enhanced to include, for example, information regarding time resource allocation, frequency resource allocation, mini-slot allocation, and or Code Block Group (CBG) transmission. Such information, or similar information, may be used in operations such as mini-slot operations, Code Block Group (CBG) transmission, group common Physical Downlink Control Channel (PDCCH), grant-free and grant-less operations, response to Beam Failure Recovery Request (BFRR), UL Transmit (TX) beam change, Quasi-Co-Location (QCL) operations, aperiodic CSI-RS transmission and interference measurement, Band Width Part (BWP) operations, and Multi-Transmission and Reception Point (TRP)/Multi-Panel.

  • Patent number: 11445545
    Abstract: Methods and apparatuses are described herein for full-duplex transmission opportunity discovery and transmission in a wireless 802.11 network A full duplex compatible access point may transmit a full duplex (FD) transmission opportunity (TxOP) setup frame to a plurality of wireless transmit/receive units (WTRUs). This enables each of the plurality of WTRUs to transmit a measurement frame for interference measurement by the each of the other WTRUs to determine which WTRUs may participate in FD communication. Feedback is received by the AP and the AP determines which of the plurality of WTRUs the AP can perform FD communication with based on the feedback. FD communication with the determined WTRUs is then commenced.

  • Publication number: 20220286184
    Abstract: A user equipment (UE) determines sidelink resources for use in vehicle wireless communications. Initial beam establishment uses a Sidelink Synchronization Signal (SLSS), a Sidelink Channel State Information Reference Signal (SL-CSI-RS), or a Sidelink Demodulation Reference Signal (SL-DMRS). Beam refinement may then be conducted either by UEs in communication with each other, or by just one of the UEs. A base station such as a gNB may assign resources for a dedicated sidelink carrier or a shared licensed sidelink carrier, e.g., dynamically, as pre-configured by RRC, or based on activation and deactivation. In such cases, initial beam establishment and refinement may include gNB controlled beam forming at a connectionless stage, gNB controlled beam forming at connection stage with scheduling DCI transmitted to Tx UE only, or gNB controlled beam forming at connection stage with scheduling DCI transmitted to both Tx UE and Rx UE.

  • Patent number: 11425752
    Abstract: Disclosed herein are new radio (NR) Data link architecture options including, for example, NR radio bearer models, NR logical channel models, and MAC and HARQ models. Further described are packet flows mapping to data radio bearers (DRBs), and a new flow encapsulation protocol in the user plane. In some embodiments, DRBs with different quality of service (QoS) are pre-established, but not activated. This allows a given user equipment (UE) to use these DRBs for packet data network (PDN) flows without a large overhead. Pre-established DRBs can be an extension to default bearer concept with the decision of pre-establishment of DRBs based on UE capability, subscription profile, operation policy, installed apps, etc.
