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: 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: The present disclosure provides methods and apparatuses for flexible radio frequency (RF) utilization and switching. In some embodiments, carriers and/or panels are activated and deactivated at an apparatus as needed, to conserve power at the apparatus. Fast carrier activation and fast panel activation are provided, to reduce carrier activation delay and panel activation delay. Round robin patterns for obtaining carrier-specific measurement information and panel-specific measurement information are also provided, to further reduce carrier and panel activation delay. Further, RF chain and/or antenna switching between multiple carriers at the apparatus is provided to improve data throughput.

Abstract: A two-stage DCI framework is provided in which the first stage DCI is carried by PDCCH, second stage DCI is carried by PDSCH. The first stage DCI is blind decoded. The second stage DCI is indicated by the first stage DCI and therefor no blind decoding is necessary. The size of the second stage DCI can be very flexible, can indicate scheduling information for one carrier, multiple carriers, multi transmission for one carrier. The first stage DCI can be compact in size to enhance reliability.

Abstract: Methods and apparatuses for measurement in a wireless communication system are provided. In some embodiments, an apparatus transmits a measurement report for one carrier and/or bandwidth part (BWP) that is based on measurement information for another carrier and/or BWP. Further, the apparatus may switch between different carriers and/or BWPs to obtain measurement information in advance of scheduling transmissions on those different carriers and/or BWPs. Potential advantages include a reduction in measurement overhead at the apparatus.

Abstract: A method in an apparatus for receiving downlink control information (DCI) are provided. A first stage DCI is scrambled by a radio network temporary identifier (RNTI) in a physical downlink control channel (PDCCH), wherein the first stage DCI explicitly indicating a scheduling information of a second stage DCI. The second stage DCI is sent in a first physical downlink shared channel (PDSCH), the first PDSCH is a physical channel without data transmission. The second stage DCI has a second stage DCI format, and the apparatus obtains the at least one second stage DCI format based on at least one of the first stage DCI and the second DCI. This allows a lot of flexibility in formats of the second stage DCI.

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: 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.
