  • Publication number: 20250261269
    Abstract: An apparatus in accordance with the present application may monitor a sidelink (SL) connection. The apparatus includes processing circuitry that receives signals in a protocol stack to perform SL-radio link monitoring (SL-RLM), and determines, according to the signals, whether a SL-radio link failure (RLF) has occurred. The signals may include hybrid automatic repeat request (HARQ) feedback. In a case that the signals include a HARQ-NACK, the processing circuitry determines that the SL-RLF has occurred. The processing circuitry further receives configuration information related to the SL-RLM for the signals, the configuration information including configurations for measurement quantities of the signals and a condition for declaring SL-RLF, configures, according to the configuration information, lower layers of the protocol stack for the SL-RLM for the signals, and performs SL-RLM measurements of the measurement quantities.

  • Patent number: 12328172
    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.
