Abstract

Methods and apparatus enabling a wireless network to dynamically change or implement paging mode operation, such as optimization based on one or more network parameters. In one embodiment, the wireless network is a cellular network (e.g., 3G UMTS or LTE), and both base stations and cellular user devices dynamically configure the paging mode operation based on various desired operational attributes relating to the network parameters. Such flexible paging mechanisms may be published to the network users via several methods, and users with appropriately enabled user devices may improve their power and applications performance. Base stations may also advantageously reclaim freed-up cellular resources to support other services. Legacy subscribers are also not affected.

Claims

1. A user equipment (UE), comprising:

a transceiver configured to establish a connected state with a cellular network; and

a baseband processor connected to the transceiver configured to;

receive timing data, wherein the timing data indicates a plurality of paging transmissions to be transmitted on at least one carrier of a plurality of aggregated carriers corresponding to the cellular network; and

when in the connected state, monitor only a first carrier of the plurality of aggregated carriers for a first paging transmission of the plurality of paging transmissions based on the timing data, wherein the cellular network allocates resources for the plurality of paging transmission based at least in part on a ratio of enhanced devices to legacy devices on the cellular network.

2. The UE of claim 1, wherein the connected state is a RRC_connected state.

3. The UE of claim 2, wherein the cellular network transmits the timing data to the UE according to a first mode of paging transmission operations based on the UE and the cellular network being in the RRC_connected state.

4. The UE of claim 1, wherein the UE receives the timing data based on the UE monitoring a Physical Downlink Control Channel (PDCCH) during at least one predetermined time interval.

5. The UE of claim 1, wherein the plurality of paging transmission is transmitted to the UE on a Physical Downlink Shared Channel (PDSCH).

6. The UE of claim 1, wherein the plurality of paging transmissions each correspond to one of a network service or a network notification specifically addressed to the UE.

7. A baseband processor, configured to perform operations comprising:

receiving timing data, wherein the timing data indicates a plurality of paging transmissions to be transmitted on at least one carrier of a plurality of aggregated carriers corresponding to a cellular network; and

when in a connected state, monitoring only a first carrier of the plurality of aggregated carriers for a first paging transmission of the plurality of paging transmissions based on the timing data, wherein the cellular network allocates resources for the plurality of paging transmission based at least in part on a ratio of enhanced devices to legacy devices on the cellular network.

8. The baseband processor of claim 7, the operations further comprising:

decoding the first paging transmission based on the timing data.

9. The baseband processor of claim 7, wherein the timing data is transmitted to the baseband processor on a Physical Downlink Control Channel (PDCCH) and the first paging transmission is transmitted to the baseband processor on a Physical Downlink Shared Channel (PDSCH).

10. The baseband processor of claim 9, wherein the PDCCH and the PDSCH are transmitted in a first subframe.

11. The baseband processor of claim 10, wherein the PDCCH occupies one of one, two or three orthogonal frequency division multiplexing (OFDM) symbols in a first slot of the first subframe.

12. The baseband processor of claim 7, wherein the connected state is a RRC_connected state.

13. A method, comprising:

at a user equipment (UE);

establishing a connected state with a cellular network;

receive timing data, wherein the timing data indicates a plurality of paging transmissions to be transmitted on at least one carrier of a plurality of aggregated carriers corresponding to the cellular network; and

when in the connected state, monitor only a first carrier of the plurality of carriers for a first paging transmission of the plurality of paging transmissions based on the timing data, wherein the cellular network allocates resources for the plurality of paging transmission based at least in part on a ratio of enhanced devices to legacy devices on the cellular network.

14. The method of claim 13, wherein the connected state is a RRC_connected state.

15. The method of claim 14, wherein the cellular network transmits the timing data to the UE according to a first mode of paging transmission operations based on the UE and the cellular network being in the RRC_connected state.

16. The method of claim 13, further comprising:

decoding the first paging transmission based on the timing data.

17. The method of claim 13, wherein the timing data is transmitted to the baseband processor on a Physical Downlink Control Channel (PDCCH) and the first paging transmission is transmitted to the baseband processor on a Physical Downlink Shared Channel (PDSCH).

18. The method of claim 17, wherein the PDCCH and the PDSCH are transmitted in a first subframe.

19. The method of claim 18, wherein the PDCCH occupies one of one, two or three orthogonal frequency division multiplexing (OFDM) symbols in a first slot of the first subframe.

20. The method of claim 13, wherein the plurality of paging transmissions each correspond to one of a network service or a network notification.
