Abstract: Aspects of the present disclosure provide methods of utilizing controllable metasurface devices capable of redirecting a wavefront transmitted by a transmitter to a receiver in the wireless network to take advantage of the controllable metasurface device capabilities, intelligence, coordination and reconfiguration speed, and thereby enable solutions having different signaling details and capability requirements. Methods described herein provide mechanisms for identification of a RIS deployed in a communication network, identification of possible RIS to UE links, setup of base station (BS) to RIS links and RIS to UE links, activation of the RIS, and configuration of UEs to receive data from the BS via redirection by the RIS.

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: Aspects of the present application provide methods and devices for use in User Equipment (UE) cooperation. A packet transmitted between a base station and a UE or between UEs includes a packet destination identifier that identifies a destination of the packet. A receiving the packet from a base station or another UE can determine whether the UE is the destination of the packet. When the UE is the destination of the packet, the UE decodes the packet. When the UE is not the destination of the packet, the UE forwards the packet to another UE. The packet may include a packet source identifier that can be used by the destination to determine where the packet originated. In some instances, the cooperative UEs do not need to decode the entire packet to be able to determine the destination of the packet and therefore can forward the packet along with less processing.

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.

Abstract: Signaling to enable relay-based user equipment (UE) cooperation (UC) by a group of UEs, and a configuration including an adaptation protocol for processing of UC bearer traffic, are communicated in a wireless communication network. The UC bearer traffic includes a UC bearer and UC bearer attributes, and the UC bearer includes either a split bearer or a duplicated bearer indicated in the UC bearer attributes. In some embodiments, wireless network connectivity that is available for a relay link is determined, and the adaptation protocol is determined based on the determined connectivity. Signaling to enable configuration of the relay link in accordance with the connectivity and the adaptation protocol is communicated. A UE may receive signaling to configure the UE for such a relay link, and communicates traffic between a remote UE and the wireless communication network over the relay link.

Abstract: Methods and systems are provided in which a UE transmits sidelink (SL) control information comprising a scheduling assignment (SA) indicating an SL transmission resource for a SL data transmission to a target UE. The SL transmission resource is based on one or more occupied SL resources identified by the UE and the SL transmission resource includes resources for an initial transmission and one or more retransmissions. The UE then transmits the SL data transmission using the SL transmission resource according to the transmitted SL control information. This is done without receiving, in a downlink control information (DCI), a grant of communication resources.

Abstract: A timing advance (TA) value is a time offset that may be applied by a UE to compensate for the propagation delay of the UE and thereby cause the UE's uplink transmissions to be time synchronized with the uplink transmissions of other UEs. However, a UE may possibly operate in different states, and in some states (e.g. a power saving state) the UE does not maintain uplink synchronization. If the UE has information to transmit, and the UE is operating in a state in which there is no uplink synchronization, then the overhead of performing uplink synchronization in order to transmit the information must be incurred. Systems and method are instead disclosed for providing TA values to maintain timing synchronization, e.g. even when the UE is in a power-saving state.

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: Systems and methods are provided to achieve data scrambling and transmission identification in the SL for UE cooperation (UC), in which one or more cooperating UEs help with a transmission to a target UE. Corresponding configuration schemes are also provided. In addition, systems and methods are provided to achieve data DMRS sequence generation and transmission identification in SL for UC, in which one or more cooperating UEs help with a transmission to a target UE. Corresponding configuration schemes are also provided. Furthermore, systems and methods of SL control channel scrambling and identification for UE cooperation are provided.

Abstract: Data is scrambled at a transmitter according to one of a number of predetermined scrambling sequences which are associated with a particular one of a number of predetermined transmit antenna diversity schemes (i.e., a specific number of transmit antenna ports). Received data is decoded using one or more of the known transmit antenna diversity schemes and the scrambled data is descrambled according to a corresponding descrambling sequence (related to the scrambling sequence). Based on the descrambled data, the receiver determines which transmit antenna diversity scheme (i.e., the number of antenna ports) is used by the transmitter. In one specific embodiment, CRC parity data is scrambled in the transmitter and the receiver descrambles the recovered CRC parity data according to a descrambling sequence, computes CRC parity data from the received data, and compares the descrambled CRC parity data to the newly computed CRC parity data.

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, there may be a plurality of uplink and/or downlink carriers, with signaling indicating addition, modification, release, activation, deactivation, and/or scheduling of a particular carrier of the uplink carriers and/or downlink carriers, e.g. on an independent carrier-by-carrier basis.

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.

The first physical layer function parameter corresponding to the first communication mode is determined by the terminal device based on the first identifier and a first correspondence between a communication mode and a physical layer function parameter. Communication is performed based on the first physical layer function parameter corresponding to the first communication mode. The communication mode in the first correspondence includes the first communication mode.
