1. A method of sending, by a network node, a power control signal according to a discontinuous reception (DRX) cycle in a radio communication between a network node and a radio device, the method comprising:
determining that there is a paging message for a radio device during an upcoming discontinuous receive cycle;
determining an indicator that, according to a scheme, uniquely identifies a subgroup of one or more radio devices comprising at least the radio device that is being paged within a group of radio devices sharing at least the same paging frame, wherein determining the indicator comprises either:
determining the indicator according to the scheme by the formula indicator=floor (UE_ID/(N*Ns)), wherein floor ( ) is a floor function, UE_ID is the radio device identity, N is the number of paging frames within the radio device DRX cycle, and Ns is the number of paging occasions used within a paging frame; or
determining the indicator according to the scheme and further based the number of paging narrowbands or paging carriers provided in system information, and wherein the indicator is determined according to the scheme by the formula indicator=floor (floor (UE_ID/(N*Ns))/Nn), wherein floor ( ) is a floor function, UE_ID is the radio device identity, N is the number of paging frames within the radio device DRX cycle, Ns is the number of paging occasions used within a paging frame, and Nn is the number of paging narrowbands or paging carriers; and
sending the power control signal for notifying the radio device which is being paged, wherein the power control signal includes the indicator.
