Publication number: 20200351733Abstract: The present disclosure relates to a mobile terminal for performing cell (re-)selection in a system with at least two suitable cells, each with a plurality of beams. The terminal is in a normal- or a high-mobility state. The terminal measures a signal quality of the beams of each of the suitable cells, determines the cell quality based on the respective measured signal qualities of the beams; and (re-)selects that cell based on a cell (re-)selection criterion using the determined cell qualities. The cell quality is determined for each one of the suitable cells as a sum of the measured signal quality of the beam, with the best signal quality, and a combined beam quality value for the other beams. The combined beam quality value is scaled with a scaling factor which changes depending on the mobility state such that the combined beam quality value is scaled-up in the high-mobility state and scaled-down in the normal-mobility state.Type: ApplicationFiled: July 17, 2020Publication date: November 5, 2020Inventors: Ming-Hung TAO, Hidetoshi SUZUKI, Ankit BHAMRI, Rikin SHAH, Yihui LI
