Abstract: A communication system may include an access point (AP), user equipment (UE) device, and reconfigurable intelligent surface (RIS). The UE may control the RIS by transmitting control signals that configure antenna elements on the RIS. The RIS may reflect wireless signals between the UE and the AP. The RIS may be known to the network. The UE may transmit a report to the AP that includes information about the RIS. The UE may receive assistance information from the AP. The UE may control the RIS based at least in part on the assistance information. The UE may transmit measurement reports to the AP. The AP may update its signal beams based on the information about the RIS and the measurement reports. Providing the network with awareness of the RIS may serve to optimize the wireless performance of the UE device and/or the network.

Abstract: Systems, methods, and processors are provided for flexibly configuring network slices in device to device communication. In one example, a baseband processor for a relay user equipment (UE) is configured to cause the UE to receive a UE route selection policy (URSP) from a network. The URSP includes respective URSP rules for routing UE traffic through respective network slices to the network. A first URSP rule indicates whether an associated first network slice is designated for remote UE traffic, relay UE traffic, or both remote UE traffic and relay UE traffic. The baseband processor is configured to cause the UE to establish a device to device (D2D) connection with a remote UE to relay remote UE traffic from the remote UE to a base station and assign the remote UE traffic to at least one network slice based on the URSP.

Abstract: A communication system may include a base station (BS), a user equipment (UE) device, a reconfigurable intelligent surface (RIS) having a local controller, and a remote controller. Antenna elements on the RIS may reflect signals between the BS and UE while exhibiting reflection coefficients. The remote controller may transmit a control model and the UE may transmit local information to the local controller, which generates the reflection coefficients based on the local information and control model. Alternatively, the remote controller may transmit the control model to the UE and a codebook to the RIS. The UE may transmit an identifier to the RIS based on local information and the control model. The local controller may implement reflection coefficients of a codebook entry identified by the identifier. Splitting control of the RIS in these ways may minimize communication overhead, provide coverage extension for the UE, and optimize privacy.
