Patent ID: 10750528

Abstract:
A terminal device and a base station device can efficiently communicate with each other by using a downlink channel. The terminal device monitors, in an EPDCCH-PRB-set p in a subframe k, a first set ESk(L) of first EPDCCH candidates and a second set ESk(L) of second EPDCCH candidates. A first number Mp,c(L) of the first EPDCCH candidates is determined according to a first αp,c and Mp(L), and a second number Mp,c(L) of the second EPDCCH candidates is determined according to a second αp,c and Mp(L). First ECCE(s) corresponding to an mth first EPDCCH candidate included in the first set ESk(L) and second ECCE(s) corresponding to an mth second EPDCCH candidate included in the second set are determined according to a first value. The first value is given by a following expression, where NECCE,p,k is a total number of ECCEs included in the EPDCCH-PRB-set p in the subframe k.
