Title:
CELL RESELECTION CONTROL METHOD, BASE STATION, AND WIRELESS TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/031602
Kind Code:
A1
Abstract:
A cell reselection control according to an embodiment is a method in a mobile communication system. This cell reselection control method comprises: step A in which a base station transmits, by broadcast signaling, a first reallocation parameter applied to wireless terminals present within a first coverage and a second reallocation parameter applied to wireless terminals present within a second coverage outside the first coverage as reallocation parameters to be used for a reallocation function; step B in which a wireless terminal present within the second coverage acquires the second reallocation parameter transmitted in the step A; and step C in which the wireless terminal performs cell reselection by using the second reallocation parameter acquired in the step B. The reallocation function is a function with which a plurality of wireless terminals in an idle mode disperse cells and/or frequencies to be reselected by the cell reselection. The second coverage is a coverage enhanced by an enhanced coverage function including repetition transmission.
