Abstract

　ユーザ装置は、基地局から送信された信号を受信し、セル再選択の実施条件を決めるパラメータを取得する手段と、セルの再選択回数を数える計数手段と、ドップラ周波数を測定する測定手段とを有する。セル再選択の実施条件は、移行先基地局からの受信信号強度が、移行元基地局からの受信信号強度よりもQhyst以上高い状態が、Treselection以上続くことである。第1条件及び第２条件双方が満たされたか否かによって、再選択待機期間を修正するか否かが決定される。第１条件は、所定の第１期間TCRmax内に行われたセルの再選択回数が第１閾値NCR以上であることである。第２条件は、第２期間TFDにわたってドップラ周波数が所定の第２閾値FDthresh以上であったことである。
