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: Signaling resource overhead associated with current communication link adaptation mechanisms can be quite large and such mechanisms typically rely upon a channel state information (CSI) feedback process that can result in poor scheduling performance. Embodiments are disclosed in which a first device channel state information characterizing a wireless communication channel between the first device and a second device, and trains a machine learning (ML) module of the first device using the CSI as an ML module input and one or more modulation and coding scheme (MCS) parameters as an ML module output to satisfy a training target. By applying the concepts disclosed herein, overhead associated with feedback for MCS selection may be reduced compared to conventional link adaptation procedures, because, once ML modules at a pair of devices have been trained, the MCS selection by the ML modules can be done without requiring the ongoing feedback of CSI.

Abstract: Restrictions associated with the use of multiple carriers in long-term evolution (LTE) and/or new radio (NR) may impede implementing a flexible personalized spectrum for different user equipments (UEs). Apparatuses, devices, and methods are instead provided in which there is more flexible spectrum utilization, e.g. in which there may be fewer restrictions and more options for configuring carriers and/or bandwidth parts (BWPs) on a UE-specific basis. As one example, in some embodiments, there is not necessarily coupling between carriers, e.g. between uplink and downlink carriers. For example, an uplink carrier and a downlink carrier may be independently indicated so as to allow the uplink carrier and downlink carrier to be independently added, released, modified, activated, deactivated, and/or scheduled.

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.
