  • Patent number: 10568008
    Abstract: The invention relates to a terminal (10) for a cellular communications network (1000). The terminal is configured to maintain a first set (S1) of at least n radio cells, wherein n is equal to or greater than three, wherein a quality measure (q) value of each of the n radio cells, which depends on a received signal power associated with reference signals transmitted in said cells and received by said terminal (10), exceeds a threshold. The terminal further determines whether a quality measure value of a further radio cell, which is not comprised in the first set, exceeds the quality measure value of the radio cell comprised in the first set with the m-th best quality measure value, m ranging from 1 to n?1, by a predetermined amount. If the quality measure value of the further radio cell (c12) exceeds the quality measure value of the m-th best radio cell, modification of the first set is arranged, whereby a second set (S2) is obtained. The second set comprises the further radio cell.
