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 method for using a paging indicator in a wireless communication system, comprising:

transmitting, to a mobile device on a paging indicator channel (PICH), a paging indicator frame comprising a paging indicator, wherein the paging indicator identifies one or more subframes on a high-speed shared data channel intended for the mobile device;

transmitting, to the mobile device 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 mobile device, the parameters being configured for use by the mobile device to receive data on the high-speed shared data channel; and

transmitting the one or more subframes on the high-speed shared data channel.

2. The method of claim 1, wherein the set of parameters further comprises a first number of subframes that the mobile device should attempt to receive on the high-speed shared data channel.

3. The method of claim 1, wherein the set of parameters further comprises a second number of subframes that the mobile device should attempt to receive on the high-speed shared data channel.

4. The method of claim 3, wherein the set of parameters further comprises a stride parameter configured to indicate to the mobile device a spacing of the one or more subframes on the high-speed shared data channel intended for the mobile device.

5. The method of claim 1, wherein the one or more subframes on the high-speed shared data channel include at least one of a paging message, mobile device specific upper layer signaling, or mobile device specific data.

6. The method of claim 1, wherein the wireless communication system is an LTE system.

7. The method of claim 6, wherein the set of parameter is based upon scope and content of data to be transmitted to the mobile device.

8. The method 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 mobile device.

9. The method of claim 1, further comprising:

scheduling the one or more subframes for transmission on the high-speed shared data channel in accordance with the set of parameters transmitted to the mobile device.

10. The method of claim 1, wherein the set of parameters comprises a hybrid automatic repeat request (HARQ) configuration.

transmitting, to the mobile device 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 mobile device, the parameters being configured for use by the mobile device to receive data on the high-speed shared data channel; and

transmitting the one or more subframes on the high-speed shared data channel.

12. The non-transitory machine-readable medium of claim 11, wherein the set of parameters further comprises a first number of subframes that the mobile device should attempt to receive on the high-speed shared data channel.
