Abstract

Systems and methodologies are described that facilitate employing a paging indicator channel in connection with high speed channels in a wireless communications network. A paging indicator transmission can be sent on the paging channel to one or more mobile devices. The paging indicator indicates that additional information such as a full paging messages, other control plane data or other user plane data is expected to be transmitted at a specific time instant (e.g., subframe) on the associated high speed channel. A set of parameters can be transmitted on common channels that specify a set of associated subframes in a high speed channel. Mobile devices can analyze the set of parameters to determine the associated subframes and receive the subframes in accordance with a schedule.

First claim

What is claimed is:

1. A wireless communications apparatus, comprising:
a memory that retains instructions to:
receive a paging indicator frame comprising a paging indicator on a paging indicator channel (PICH), wherein the paging indicator identifies one or more subframes on a high-speed shared data channel intended for the wireless communication apparatus;
receive, on a high-speed shared control channel, a set of parameters, wherein the set of parameters comprise a timing offset between the end of the paging subframe and the beginning of the one or more subframes on the high-speed shared data channel intended for the wireless communication apparatus, the parameters being configured for use by the wireless communication apparatus to receive data on the high-speed shared data channel;
receive, on the high-speed shared data channel, the one or more subframes; and
decode the one or more subframes in accordance with the set of parameters; and

a processor coupled to the memory, configured to execute the instructions retained in the memory.

2. The wireless communications apparatus of claim 1 , wherein the paging indicator indicates that at least one of a paging message, wireless communications apparatus specific upper layer signaling, or wireless communications apparatus specific data is scheduled on the high-speed shared data channel.

3. The wireless communications apparatus of claim 2 , wherein the high-speed shared data channel is a high-speed physical downlink shared channel (HS-PDSCH).

4. The wireless communications apparatus of claim 1 , wherein the memory further retains instructions to configure the wireless communication apparatus based at least in part on the set of parameters.

5. A wireless communications apparatus, comprising:
means for receiving a paging indicator frame comprising a paging indicator on a paging indicator channel (PICH), wherein the paging indicator identifies one or more subframes on a high-speed shared data channel intended for the wireless communication apparatus;
means for receiving, on a high-speed shared control channel, a set of parameters, wherein the set of parameters comprise a timing offset between the end of the paging subframe and the beginning of the one or more subframes on the high-speed shared data channel intended for the wireless communication apparatus, the parameters being configured for use by the wireless communication apparatus to receive data on the high-speed shared data channel;
means for receiving, on the high-speed shared data channel, the one or more subframes; and
means for decoding the one or more subframes in accordance with the set of parameters.

6. The wireless communications apparatus of claim 5 , wherein the paging indicator indicates that at least one of a paging message, wireless communications apparatus specific upper layer signaling, or wireless communications apparatus specific data is scheduled on the high-speed shared data channel.

7. The wireless communications apparatus of claim 6 , wherein the high-speed shared data channel is a high-speed physical downlink shared channel (HS-PDSCH).

8. The wireless communications apparatus of claim 5 , further comprising means for configuring the wireless communications apparatus based at least in part on the set of parameters.

9. A non-transitory machine-readable medium for wireless communications by a wireless communication apparatus, comprising machine-executable instructions for:
receiving a paging indicator frame comprising a paging indicator on a paging indicator channel (PICH), wherein the paging indicator identifies one or more subframes on a high-speed shared data channel intended for the wireless communication apparatus;
receiving, on a high-speed shared control channel, a set of parameters, wherein the set of parameters comprise a timing offset between the end of the paging subframe and the beginning of the one or more subframes on the high-speed shared data channel intended for the wireless communication apparatus, the parameters being configured for use by the wireless communication apparatus to receive data on the high-speed shared data channel;
receiving, on the high-speed shared data channel, the one or more subframes; and
decoding the one or more subframes in accordance with the set of parameters.

10. The machine-readable medium of claim 9 , wherein the paging indicator indicates that at least one of a paging message, wireless communication apparatus specific upper layer signaling, or wireless communication apparatus specific data is scheduled on the high-speed shared data channel.

11. The machine-readable medium of claim 10 , wherein the high-speed shared data channel is a high-speed physical downlink shared channel (HS-PDSCH).

12. The machine-readable medium of claim 9 , further comprising machine-executable instructions for configuring the wireless communication apparatus based at least in part on the set of parameters.

13. A method performed by a wireless communication apparatus, comprising:
receiving a paging indicator frame comprising a paging indicator on a paging indicator channel (PICH), wherein the paging indicator identifies one or more subframes on a high-speed shared data channel intended for the wireless communication apparatus;
receiving, on a high-speed shared control channel, a set of parameters, wherein the set of parameters comprise a timing offset between the end of the paging subframe and the beginning of the one or more subframes on the high-speed shared data channel intended for the wireless communication apparatus, the parameters being configured for use by the wireless communication apparatus to receive data on the high-speed shared data channel;
receiving, on the high-speed shared data channel, the one or more subframes; and
decoding the one or more subframes in accordance with the set of parameters.

14. The method of claim 13 , wherein the paging indicator indicates that at least one of a paging message, wireless communication apparatus specific upper layer signaling, or wireless communication apparatus specific data is scheduled on the associated high speed channel.

15. The method of claim 14 , wherein the high-speed shared data channel is a high-speed physical downlink shared channel (HS-PDSCH).

16. The method of claim 13 , further comprising configuring the wireless communication apparatus based at least in part on the set of parameters.

17. The wireless communication apparatus of claim 1 , wherein a timing of the paging indicator frame is based at least in part on the discontinuous reception (DRX)/wake up cycle of the wireless communication apparatus.

18. The wireless communication apparatus of claim 5 , wherein a timing of the paging indicator frame is based at least in part on the discontinuous reception (DRX)/wake up cycle of the wireless communication apparatus.

19. The non-transitory machine-readable medium of claim 9 , wherein a timing of the paging indicator frame is based at least in part on the discontinuous reception (DRX)/wake up cycle of the wireless communication apparatus.

20. The method of claim 13 , wherein a timing of the paging indicator frame is based at least in part on the discontinuous reception (DRX)/wake up cycle of the wireless communication apparatus.
