Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Submission Under 35 U.S.C. § 371 for U.S. National Stage Patent Application of International Application Number: PCT/SE2021/050070, filed Jan. 31, 2021 entitled “DATA SIGNALING FOR WIRELESS COMMUNICATION NETWORKS,” the entirety of which is incorporated herein by reference. TECHNICAL FIELD This disclosure pertains to wireless communication technology, in particular for high frequencies. BACKGROUND For future wireless communication systems, use of higher frequencies is considered, which allows large bandwidths to be used for communication. However, use of such higher frequencies brings new problems, for example regarding physical properties and timing. Ubiquitous or almost ubiquitous use of beamforming, with often comparatively small beams, may provide additional complications that need to be addressed; also, new waveforms may be considered, e.g. to facilitate low PAPR. SUMMARY It is an object of this disclosure to provide improved approaches of handling wireless communication, in particular of data signaling. The approaches are particularly suitable for millimeter wave communication, in particular for radio carrier frequencies around and/or above 52.6 GHz, which may be considered high radio frequencies (high frequency) and/or millimeter waves. The carrier frequency/ies may be between 52.6 and 140 GHz, e.g. with a lower border between 52.6, 55, 60, 71 GHz and/or a higher border between 71, 72, 90, 114, 140 GHz or higher, in particular between 55 and 90 GHz, or between 60 and 72 GHz; however, higher frequencies may be considered. The carrier frequency may in particular refer to a center frequency or maximum frequency of the carrier. The radio nodes and/or network described herein may operate in wideband, e.g. with a carrier bandwidth of 1 GHz or more, or 2 GHz or more, or even larger, e.g. up to 8 GHz; the scheduled or allocated bandwidth may be the carrier bandwidth, or be smaller, e.g. depending on channel and/or procedure. In some cases, operation may be based on an OFDM waveform or a SC-FDM waveform (e.g., downlink and/or uplink), in particular a FDF-SC-FDM-based waveform. However, operation based on a single carrier waveform, e.g. SC-FDE (which may be pulse-shaped or Frequency Domain Filtered, e.g. based on modulation scheme and/or MCS), may be considered for downlink and/or uplink. In general, different waveforms may be used for different communication directions. Communicating using or utilising a carrier and/or beam may correspond to operating using or utilising the carrier and/or beam, and/or may comprise transmitting on the carrier and/or beam and/or receiving on the carrier and/or beam. The approaches are particularly advantageously implemented in a 5th or 6th Generation (5G) telecommunication network or 5G radio access technology or network (RAT/RAN), in particular according to 3GPP (3rd Generation Partnership Project, a standardisation organization). A suitable RAN may in particular be a RAN according to NR, for example release 15 or later, or LTE Evolution. However, the approaches may also be used with other RAT, for example future 5.5G or 6G systems or IEEE based systems.
