Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for transmission configuration indication, TCI, management in near-field, NF, are described. A wireless transmit-receive unit, WTRU, may be configured with multiple TCI sets. Each TCI set may consist of TCI states of NF beams and a TCI state of far-field, FF, beam.

Abstract: Extended Reality (XR) applications may require high throughput and very low latency. New Radio (NR) Wireless receiver/transmitter units (WTRUs) running XR applications (XR-WTRUs) may be confronted with link failures when these applications are used in dense urban or indoor environments because of these devices operating in the millimeter band. Methods and devices are provided therefore for performing cell selection and beam management proactively to avoid link failure due to objects being in line of sight between the XR-WTRU and a network node with which it has established a connection. XR-WTRUs may therefore perform visual sensing that may enable visualizing current and future radio environment and using this information to prevent link failures by handing the XR-WTRU over to an alternative network node in line of sight of the XR-WTRU before the XR-WTRU is no longer in line of sight of the network node with which it has established a connection.
