Abstract: Devices and methods are provided for receiving a first indication and a second indication, the first indication associated with a first set of transmission parameter information for a first repetition of data received in a Physical Downlink Shared Channel (PDSCH) and the second indication associated with a second set of transmission parameter information for a second repetition of data received in the PDSCH. Each set of transmission parameter information corresponds to a Quasi-Co-Location (QCL) information for the respective repetition of data. In addition, the method involves receiving a first PDSCH repetition and a second PDSCH repetition. A channel estimate can then be performed for the first PDSCH repetition based on the QCL information for the first PDSCH repetition and a channel estimate for the second PDSCH repetition based on the QCL information for the second PDSCH repetition.

Abstract: When a user equipment (UE) is wirelessly communicating with a network, the wireless channel conditions may sometimes result in a low signal-to-noise ratio (SNR). The low SNR may be a result of the UE having poor geometry, e.g. the UE is at a cell edge. It is desired to increase the reliability of wireless communications in low SNR conditions. In some embodiments, less information may be dynamically signaled in the downlink control information (DCI), thereby allowing for a possibly lower effective coding rate.

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: The present disclosure relates to configurable modulation in wireless communications. Constellation set signaling and constellation selection signaling are communicated in a wireless communication network. The constellation set signaling is associated with modulation of data using each constellation in a constellation set that includes multiple constellations. The constellation selection signaling is indicative of one of the multiple constellations of the constellation set that is to be used in modulation of data for transmission in the wireless communication network. Data that is modulated using the one of the multiple constellations is also communicated in the wireless communication network.
