Publication number: 20240381380Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are described that may be implemented in a wireless transmit/receive unit (WTRU) for sidelink (SL) communication. In one representative method, the WTRU estimates a primary direction for a SL transmission. The first WTRU derives a paired direction associated with the primary direction. SL control information (SCI) sensing in the primary and paired directions may be performed to detect SL transmissions and/or reservations from other WTRUs. The WTRU may select a SL resource using any sensed SCI in the primary and paired directions. The WTRU may proceed to transmit SL control and data over the selected SL resource, such as in a SL slot. For example, the transmission of SL control information may include SCI transmission in the primary and paired directions in the same symbols of a slot.Type: ApplicationFiled: August 31, 2022Publication date: November 14, 2024Inventors: Umer Salim, Sanjay Goyal, Ashutosh Srivastava, Ravikumar Pragada

Publication number: 20230292347Abstract: A method for selecting resources for a transmission between a first UE and a second UE is disclosed. A set of coordination resources is determined at the first UE. The set of coordination resources includes coordination information which may indicate whether the set of coordination resources are preferred resources and/or non-preferred resources.
