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.

Claims

1. A wireless communications apparatus that retrieves information on high speed channels, comprising:

a memory that retains instructions to receive a transmission on a paging indicator channel, ascertain a set of parameters included in common channels that specify a configuration of corresponding data on a high speed channel and decode the corresponding data 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 transmission is a paging indicator that indicates that at least one of a paging message, mobile device specific upper layer signaling, or mobile device specific data is scheduled on the associated high speed channel.

3. The wireless communications apparatus of claim 2, wherein the associated high speed channel is at least one of a high speed shared control channel (HS-SCCH) in HS-SCCH operations or a high speed shared data channel in HS-SCCH less operations.

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

5. The wireless communications apparatus of claim 1, wherein the set of parameters include at least one of a number of subframes on the high speed channel associated with the paging indicator, a number of HARQ retransmissions, a stride in subframes of HARQ retransmission or a number of subframes on the high speed channel that should be monitored following receipt of the associated subframes.

6. A wireless communications apparatus that retrieves information on high speed channels, comprising:

means for receiving a transmission on a paging indicator channel;

means for ascertaining a set of parameters included in common channels that specify a configuration of corresponding data on a high speed channel; and

means for decoding the corresponding data in accordance with the set of parameters.

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

8. The wireless communications apparatus of claim 7, wherein the associated high speed channel is at least one of a high speed shared control channel (HS-SCCH) in HS-SCCH operations or a high speed shared data channel in HS-SCCH less operations.

9. The wireless communications apparatus of claim 6, further comprising means for configuring a mobile device based at least in part on the ascertained set of parameters.

10. The wireless communications apparatus of claim 6, wherein the set of parameters include at least one of a number of subframes on the high speed channel associated with the paging indicator, a number of HARQ retransmissions, a stride in subframes of HARQ retransmission or a number of subframes on the high speed channel that should be monitored following receipt of the associated subframes.

11. A non-transitory machine-readable medium having stored thereon machine-executable instructions for:

receiving a transmission on a paging indicator channel;

ascertaining a set of parameters included in common channels that specify a configuration of corresponding data on a high speed channel; and

decoding the corresponding data in accordance with the set of parameters.

12. The machine-readable medium of claim 11, wherein the transmission is a paging indicator that indicates that at least one of a paging message, mobile device specific upper layer signaling, or mobile device specific data is scheduled on the associated high speed channel.

13. The machine-readable medium of claim 12, wherein the associated high speed channel is at least one of a high speed shared control channel (HS-SCCH) in HS-SCCH operations or a high speed shared data channel in HS-SCCH less operations.

14. The machine-readable medium of claim 11, further comprising machine-executable instructions for configuring a mobile device based at least in part on the ascertained set of parameters.

15. The machine-readable medium of claim 11, wherein the set of parameters include at least one of a number of subframes on the high speed channel associated with the paging indicator, a number of HARQ retransmissions, a stride in subframes of HARQ retransmission or a number of subframes on the high speed channel that should be monitored following receipt of the associated subframes.

16. A method for retrieving information on high speed channels, comprising:

receiving a transmission on a paging indicator channel;

ascertaining a set of parameters included in common channels that specify a configuration of corresponding data on a high speed channel; and

decoding the corresponding data in accordance with the set of parameters.

17. The method of claim 16, wherein the transmission is a paging indicator that indicates that at least one of a paging message, mobile device specific upper layer signaling, or mobile device specific data is scheduled on the associated high speed channel.

18. The method of claim 17, wherein the associated high speed channel is at least one of a high speed shared control channel (HS-SCCH) in HS-SCCH operations or a high speed shared data channel in HS-SCCH less operations.

19. The method of claim 16, further comprising configuring a mobile device based at least in part on the ascertained set of parameters.

20. The method of claim 16, wherein the set of parameters include at least one of a number of subframes on the high speed channel associated with the paging indicator, a number of HARQ retransmissions, a stride in subframes of HARQ retransmission or a number of subframes on the high speed channel that should be monitored following receipt of the associated subframes.
