Abstract

There is provided a method for use in a user equipment when the user equipment is in idle mode or any other low activity state, and when the user equipment bandwidth is smaller than the cell transmission bandwidth. The method comprises the steps of determining a paging position of the user equipment in the frequency domain; receiving, from the network, paging information within the user equipment reception bandwidth; and changing, if indicated by the network, the paging position of the user equipment within the cell transmission bandwidth.

Claims (30)

1. A method implemented by a user equipment (UE), the method comprising:

the UE determining a paging position in the frequency domain for the UE based on a plurality of selection parameters received via a network broadcast signal, wherein each selection parameter of the plurality of selection parameters is associated with a respective paging position of a plurality of paging positions in the frequency domain, the plurality of selection parameters are used to distribute UEs across the plurality of paging positions, the determined paging position is less than or equal to a first frequency bandwidth, the first frequency bandwidth is less than or equal to a reception bandwidth of the UE, and the first frequency bandwidth is less than a cell transmission bandwidth of a cell;

the UE monitoring for paging indications at the determined paging position; and

the UE receiving a first paging indication at the determined paging position.

2. The method as in claim 1 , further comprising the UE receiving a paging message within the reception bandwidth of the UE.

3. The method as in claim 1 , further comprising the UE receiving a system information broadcast that indicates information related to the paging position within the transmission bandwidth of the cell.

4. The method as in claim 1 , wherein multiple repetitions of the paging indication are received.

5. The method as in claim 1 , wherein the paging indication is received while the UE is in idle mode.

6. The method as in claim 1 , wherein the plurality of selection parameters correspond to probabilities, and each respective selection parameter corresponds to a respective probability for a respective paging position.

7. The method as in claim 1 , wherein the plurality of selection parameters is associated with a non-uniform distribution of UEs across the plurality of paging positions.

8. A user equipment (UE) comprising:

a processor configured to determine a paging position in the frequency domain based on a plurality of selection parameters received via a network broadcast signal, wherein each selection parameter of the plurality of selection parameters is associated with a respective paging position of a plurality of paging positions in the frequency domain, and the plurality of selection parameters distribute UEs across the plurality of paging positions;

a receiver configured to be tuned to a frequency associated with the determined paging position, wherein the determined paging position is less than or equal to a first frequency bandwidth, the first frequency bandwidth is less than or equal to a reception bandwidth of the UE, and the first frequency bandwidth is less than the transmission bandwidth of the cell; and

the processor further configured to:

monitor, via the receiver, for paging indications at the determined paging position, and

receive, via the receiver, a first paging indication at the determined paging position.

9. The UE as in claim 8 , wherein the processor is configured to receive a first paging message within the reception bandwidth of the UE.

10. The UE as in claim 9 , wherein the processor is configured to receive each of the first paging indication and the first paging message without having to re-tune the receiver.

11. The UE as in claim 8 , wherein the processor is configured to monitor for paging indications while operating in IDLE mode.

12. The UE as in claim 8 , wherein the processor is further configured to receive, via the receiver, a system information broadcast that includes information related to the paging position within the transmission bandwidth of the cell.

13. The UE as in claim 8 , wherein the processor is configured to monitor for paging indications while performing discontinuous reception (DRX).

14. The UE as in claim 8 , wherein the processor is configured to receive, via the receiver, multiple repetitions of a paging message.

15. The UE as in claim 8 , wherein the plurality of selection parameters correspond to probabilities, and each respective selection parameter corresponds to a respective probability for a respective paging position.

16. The UE as in claim 8 , wherein the plurality of selection parameters is associated with a non-uniform distribution of UEs across the plurality of paging positions.

17. A base station configured to:

determine a paging position in the frequency domain for a User Equipment (UE) for a cell served by the base station, wherein the determined paging position is less than or equal to a first frequency bandwidth, the first frequency bandwidth is less than or equal to a reception bandwidth of the UE, and the first frequency bandwidth is less than a cell transmission bandwidth of the cell;

send a broadcast signal comprising a plurality of selection parameters, wherein each selection parameter of the plurality of selection parameters is associated with a respective paging position of a paging positions in the frequency domain, and the plurality of selection parameters are used to distribute UEs across the plurality of paging positions; and

send a first paging indication to the UE at the determined paging position.

18. The base station as in claim 17 , wherein the plurality of selection parameters correspond to probabilities, and each respective selection parameter corresponds to a respective probability for a respective paging position.

19. The base station as in claim 17 , further comprising changing one or more of the plurality of selection parameters based on radio resource usage, wherein changing the plurality of selection parameters changes the distribution of UEs across the plurality of paging positions.
