Abstract
A technique for idle mode paging in a radio communication between a network node and a radio device is described. More specifically, and without limitation, methods and devices are provided for sending and receiving a power control signal in a radio communication between a network node and a radio device. According to a general aspect, the power control signal for notifying a radio device which is being paged includes 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.
Claims11
A device for sending a power control signal according to a discontinuous reception (DRX) cycle in a radio communication between the device and a radio device, the device comprising at least one processor and a memory, said memory comprising instructions executable by said at least one processor, whereby the device is operative to:
- determine that there is a paging message for a radio device during an upcoming discontinuous receive cycle;
- and
- send the power control signal for notifying the radio device which is being paged, wherein the power control signal includes an indicator that, according to a scheme, 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 the indicator is:
- either determined 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 determined according to the scheme and further based on 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

- and
- determine, based on the received indicator and according to the scheme, whether or not the indicator identifies the radio device that is receiving the power control signal as the radio device which is being paged.
