    Abstract: Systems, devices, and methods of the present invention facilitate secure communication by changing sets of symbol waveforms used transmit data in particular symbol times defined herein as Symbol Waveform Hopping. SWH may be enabled by selecting two or more modulation formats that have sufficiently comparable communication performance (e.g., occupied bandwidth and signal power efficiency) to enable successful sending of data between a transmitter and receiver employing SWH, but characterized by symbol waveform alphabet that include different symbol waveform, so that the overall transmission/communication performance of data stream in a signal transmission channel of the system is not significantly affected by switching between modulation formats, but one symbol waveform alphabet is not reliably able to receive signals sent using the other alphabets. Some or all of the symbol waveforms in each alphabet may not be present in other alphabets.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a priority of CSI reporting in a mobile communication system, and provides a method in which a UE performs CSI reporting with high priority according to the priority. The method includes receiving channel state information (CSI) feedback configuration information from a base station; identifying a CSI reporting to be performed based on the CSI feedback configuration information, as a result of two CSI reportings overlapping; and performing the identified CSI reporting to the base station. The CSI reporting is identified based on types of CSI reportings, and a CSI reporting associated with a reference signal received power (RSRP) is prioritized over a CSI reporting that is not associated with the RSRP.

    Abstract: A network node configured to communicate with a plurality of wireless devices is provided. The network node includes processing circuitry configured to: receive partial Channel State Information, CSI, from each of the plurality of wireless devices; determine a first plurality of precoders based at least in part on the partial CSI received from each of the plurality of wireless devices where each precoder of the first plurality of precoders is associated with a respective one of the plurality of wireless devices; determine a second plurality of precoders based at least in part on the first plurality of precoders; and optionally cause multiple-user multiple-input multiple-output, MU-MIMO, transmission to the plurality of wireless devices based at least in part on the plurality of second precoders.
