Abstract: Methods for transmitting and receiving downlink control information (DCI) are provided along with corresponding network devices and apparatus. A first stage DCI is transmitted that explicitly indicates a scheduling information of a second stage DCI. The second stage DCI is transmitted in a first physical downlink shared channel (PDSCH), consistent with the scheduling information. The first PDSCH is a physical channel without data transmission. The receiving apparatus does not need to perform blind decoding of the second stage DCI because it is aware of its location from the scheduling information.

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: An air interface is the wireless communications link between two or more communicating devices. An air interface generally includes a number of components that specify how a transmission is to be sent and/or received, e.g. components defining a waveform, a frame structure, a multiple access scheme, a coding scheme, etc. Artificial intelligence (AI) may be implemented in relation to one or more components of the air interface. Therefore, a network may need to accommodate operation for both air interfaces that are not AI enabled and air interfaces that are AI enabled. In some embodiments, methods are provided for switching between different AI modes and a non-AI mode. In some embodiments, a measurement signaling mechanism and related feedback channel configuration is provided so that the same measurement signaling mechanism and related feedback channel may be used regardless of whether a device implements an AI-enabled air interface.

Abstract: According to the present disclosure, there are provided methods and devices for estimating a high-dimensional MIMO channel by expressing the MIMO channel in the form of a flow function to determine a change from an input state to an output state. This may be considered similar to a manner in which fluid dynamic problems are solved. Instead of using linearization to estimate all of the coefficients of a matrix representing a MIMO channel, a receiver may determine the MIMO channel rank by detecting leading modes in a subspace of the entire MIMO channel matrix.

Abstract: Systems and methods of integrated sensing and communication are provided. These involve using a communications network for the exchange of both communications signals and sensing signals. A device on the network, which might be a user equipment or a network device, uses a first set of channels to transmit sensing signals for use in cooperative sensing involving a multiple devices, which may include user equipment and/or network devices, for sensing a target that is not registered in the network, such as a building. The device uses a second set of channels to transmit a communications signal. The second set of channels includes at least one channel not included in the first protocol stack.

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 for configuring devices to passively identify themselves even while not actively engaged in accessing a network. Upon receipt of a sensing signal, passive device components of a given device form a backscatter signal that is an altered version of the sensing signal. The source of the sensing signal, or an appropriately configured network node, upon receipt of the backscatter, may identify the given device by the nature of the alteration. The source of the sensing signal, or the appropriately configured network node, may then be considered to have gained information on the existence of the given device as well as a general location for the given device. The network may enlist the help of other devices to sense the environment and, by doing so, may ultimately achieve a greater degree of resolution of the sensed environment.

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.
