Abstract: A first sensing coordinator in a radio access network may communicate a first signal with a second sensing coordinator through an interface link. The first sensing coordinator may include a sensing protocol layer, and may communicate the first signal through the interface link using the sensing protocol. Similarly, a second sensing coordinator may communicate a first signal with a first sensing coordinator in a radio access network through an interface link, with the second sensing coordinator including a sensing protocol layer and communicating the first signal through the interface link using the sensing protocol. A sensing device or apparatus may access an interface link through a radio access network and communicate a first signal, including a sensing configuration or sensing data, with a sensing coordinator that has a sensing protocol layer. The communicating may involve communicating the first signal through the interface link using a sensing protocol.

Abstract: Some embodiments of the present disclosure provide a transmit receive point (TRP) with sensing abilities. Through sensing over time, the TRP can obtain details of past locations of a user equipment (UE) and a current location of the UE. Furthermore, the TRP can predict a future location for the UE. Accordingly, the TRP can proactively arrange for switching of beam directions used for both downlink channels and uplink channels.

Abstract: Some embodiments of the present disclosure provide for configuration of a sensing signal on the basis of received information regarding a preferred direction or index of sensing signal. The configured sensing signal may be indicated to another device using a predetermined coordinate system. The indication may be transmitted over a communication link ahead of the transmission of the sensing signal.

Abstract: Some embodiments of the present disclosure provide a transmit receive point (TRP) with sensing abilities. Through sensing over time, the TRP can obtain details of past locations of a user equipment (UE) and a current location of the UE. Furthermore, the TRP can predict a future location for the UE. Accordingly, the TRP can proactively arrange for switching of beam directions used for both downlink channels and uplink channels. Aspects of the present application relate to a unified physical layer beam switch mechanism for intra-cell mobility and inter-cell mobility. Intra-cell beam switching, wherein a to-be-activated beam is from the same cell as the existing beam, may be triggered by physical layer signaling or media access control signaling. Inter-cell beam switching, wherein a to-be-activated beam is from a different cell than the existing beam, may be triggered by physical layer signaling or media access control signaling.

Abstract: Some embodiments of the present disclosure provide proactive beam failure recovery initiation. The proactive initiation may occur at the transmit receive point or at the user equipment. Beam failure, which leads to the beam failure recovery initiation may be proactively detected using sensing or artificial intelligence. A part of any beam failure recovery process is new beam identification. Such new beam identification may be carried out in a traditional manner, using reference signal beam measurement and training. Alternatively, new beam identification may be carried out in a proactive manner, using sensing or artificial intelligence. When indicating a direction for the new beam, a coordinate system may be used. The indicating may reference an absolute beam direction or a differential beam direction by using the coordinate system.

Abstract: Some embodiments of the present disclosure provide beam indication solutions. A first solution relates to absolute beam indication and a second solution relates to differential beam indication. Through, for example, information determined using sensing, these beam indication solutions allow for information transfer between transmit receipt point and user equipment to occur on a relatively narrow beam. By reducing scanning, a solution based on beam indication aspects of the present application reduce overhead and, consequently, reduce latency. Another benefit of a narrow beam is improved spectral efficiency. The sensing may allow for a relationship between a beam and an external environment to be established. The relationship allows for a beam to be indicated in a direct and agile manner.
