    Abstract: Embodiments of the application may produce a dramatic reduction in reference signal overhead, enabling channel estimation and acquisition of MIMO with a very large bandwidth in the 10˜13 GHz range and a very ultra large number of antenna ports and a very large number of transmission layers, and exploit channel correlation in time/frequency/spatial domain. Firstly, a new signaling to indicate the topology structure of channel vectors is provided. Secondly, UE behavior is defined in terms of channel estimation and interpolation, based on the indicated topology structure. Thirdly, reference signal patterns are derived, again based on the topology structure.

    Abstract: Some embodiments of the present disclosure provide for multiplexing sensing signals and communication signals in a spatial domain, a frequency domain and a time domain. In some instances, a sensing signal may be used for communication. Signals of three types are considered: communication-only; sensing-only; and joint sensing and communication. The types of signals may be distinguished by their waveform and/or numerology configurations. Spatial domain multiplexing may be enabled by establishing an association between a three-dimensional resource block and a signal configuration. The three-dimensional resource block may be defined using a spatial domain element, a frequency domain element and a time domain element.

    Abstract: Aspects of the present disclosure provide methods and apparatuses for protecting a reference signal (RS) and/or adjusting timing advance (TA) values to be used for timing synchronization between an apparatus (e.g. user equipment (UE))) and a device (e.g. transmit-and-receive point (TRP)) in a wireless network. The device operates in full-duplex (FD) mode and the apparatus operates in half-duplex (HD) or FD mode. In some embodiments, RSs transmitted in uplink and downlink directions are protected by puncturing one or more portions of time-frequency resources so that interference from other signals can be avoided or mitigated. The punctured portion of the time-frequency resources may be one or more symbols that together overlaps with a symbol at which the RS is to be received or sent. The device may send information indicating the portion to puncture using a higher-layer signaling, a dynamic signaling, or a preconfiguration by the network.

    IPC: H04W64/00

    Abstract: Aspects of the present application relate to sensing-based, mobility-aware waveform adaptation. A transmitting device may estimate a velocity vector for a mobile device. The velocity vector estimate may be based on measurements made at the mobile device and fed back to the transmitting device or based on measurements made at other devices in the environment and provided to the transmitting device. The transmitting device may, based on the estimate of the velocity vector, obtain a Doppler variable estimate for a signal path between the transmitting device and the mobile device. The transmitting device may then adapt a to-be-transmitted waveform based on the Doppler variable estimate for the signal path and then transmit the adapted waveform. Occasionally, the transmitting device may obtain updates to parameters that describe the location and mobility of the mobile device. On the basis of the updates, the transmitting device may update the waveform adaptation.

    Abstract: Some embodiments of the present disclosure provide initial access procedures that allow a UE to become connected to a non-terrestrial transmit-receive point, such as a device in a high altitude platform system. Through receipt of a positioning reference signal, a UE may determine its own location coordinates. Then, using the location coordinates, the UE may select a beam using a set of parameters associated, in a table, with the location coordinates. The UE may then use the selected beam to carry out an initial access procedure with the non-terrestrial transmit-receive point.

    Abstract: In accordance with implementations, a device determines an AI/ML model training capability of the device. The AI/ML model training capability indicates a capability of the device to contributively participate in an AI/ML model training process with at least a second device in a wireless communication network. The AI/ML model training capability is determined based on at least one of a current processing capability of the device, a current volume of training data available for the AI/ML model training process at the device, or a sensing capacity of the device to collect the training data for the AI/ML model training process. The device then transmits the AI/ML model training capability to the second device.

    Abstract: Embodiments of this application provide a space indication method and a communication apparatus, and relate to the field of communication technologies. A first communication apparatus receives first indication information from a second communication apparatus, where the first indication information includes structure information of first sensing space, and the structure information of the first sensing space includes first information indicating a first tree structure of the first sensing space; determines the tree structure of the first sensing space based on the first indication information; determines feedback information based on the tree structure of the first sensing space, where the feedback information indicates status information sensed by the first communication apparatus in the first sensing space or status information sensed by the first communication apparatus outside the first sensing space; and sends the feedback information to the second communication apparatus.
