Abstract

A method, system, and machine-readable medium for transmitting a downlink signal in a substantially non directional manner from a communication station to a first remote communication device on a downlink channel. The communication station includes a smart antenna system having an array of antenna elements. The method includes determining a first downlink smart antenna processing strategy for transmitting in a first non-directional manner, transmitting a first downlink message from the communication station in the first non-directional manner using the first downlink smart antenna processing strategy, and repeating transmitting the first downlink message from the communication station in a second non-directional manner. The repeated transmitting is non-identical repetition to facilitate the interference environment being different in the repetition.

Claims

1. A method for receiving a paging signal in a data frame from a base station, the frame defined by a communication protocol as having a group of sequential time slots being data transfer periods within the frame, comprising:

receiving a paging signal at a mobile user terminal in a sub-period of a data transfer period of a data frame as defined by the communication protocol;

receiving a repetition of the paging signal in a different sub-period of the data frame to provide different spatial signatures between the paging signal and the repetition of the paging signal, wherein the repetition is one of one or more repetitions, where the number of repetitions is based on estimation of proximity of the mobile user terminal to the base station, the estimation based on data sent from the mobile user terminal to the base station in a negotiation sequence; and

processing the paging signal and the repetition of the paging signal to obtain paging data.

2. The method of claim 1, wherein receiving the paging signal in the sub-period of the data transfer period comprises:

receiving the paging signal in a sub-timeslot of a downlink timeslot.

3. The method of claim 2, wherein receiving the paging signal in the sub-timeslot comprises:

receiving the paging signal in a half-slot of the downlink timeslot.

4. The method of claim 1, wherein receiving the paging signal in the sub-period of the data transfer period comprises:

receiving the paging signal in a sub-frequency-band of a downlink frequency band.

5. The method of claim 4, wherein receiving the paging signal in the sub-frequency-band comprises:

receiving the paging signal in a frequency band one half the bandwidth of the data transfer frequency band.

6. The method of claim 1, wherein receiving the repetition of the paging signal comprises:

receiving the repetition of the paging signal in a sub-period of a different data transfer period of the data frame.

7. The method of claim 1, wherein receiving the repetition of the paging signal comprises:

receiving a signal having adjusted signal transmission characteristics to account for changes in an interference environment associated with the paging signal.

8. An article of manufacture comprising a machine-accessible storage medium having information representing instructions, which when executed, cause a mobile user terminal transceiver system including a processor to perform operations including the user terminal to:

receive a paging signal in a sub-period of a data transfer period of a data frame as defined by the communication protocol, the data frame defined by a communication protocol as having a group of sequential slots;

receive a repetition of the paging signal in a different sub-period of the data frame to provide different spatial signatures between the paging signal and the repetition of the paging signal, wherein the repetition is one of one or more repetitions, where the number of repetitions is based on estimation of proximity of the mobile user terminal to the base station, the estimation based on data sent from the mobile user terminal to the base station in a negotiation sequence; and

process the paging signal and the repetition of the paging signal to obtain paging data.

9. The article of manufacture of claim 8, wherein the instructions to cause the user terminal to receive the paging signal in the sub-period of the data transfer period comprises instructions to cause the user terminal to:

receive the paging signal in a sub-timeslot of a downlink timeslot.

10. The article of manufacture of claim 9, wherein the instructions to cause the user terminal to receive the paging signal in the sub-timeslot comprises instructions to cause the user terminal to:

receive the paging signal in a half-slot of the downlink timeslot.

11. The article of manufacture of claim 8, wherein the instructions to cause the user terminal to receive the paging signal in the sub-period of the data transfer period comprises instructions to cause the user terminal to:

receive the paging signal in a sub-frequency-band of a downlink frequency band.

12. The article of manufacture of claim 11, wherein the instructions to cause the user terminal to receive the paging signal in the sub-frequency-band comprises instructions to cause the user terminal to:

receive the paging signal in a frequency band one half the bandwidth of the data transfer frequency band.

13. The article of manufacture of claim 8, wherein the instructions to cause the user terminal to receive the repetition of the paging signal comprises instructions to cause the user terminal to:

receive the repetition of the paging signal in a sub-period of a different data transfer period of the data frame.

14. The article of manufacture of claim 8, wherein the instructions to cause the user terminal to receive the repetition of the paging signal comprises instructions to cause the user terminal to:

receive a signal having adjusted signal transmission characteristics to account for changes in an interference environment associated with the paging signal.

15. A user terminal in a wireless communication system that receives a paging signal in a data frame from a base station, the frame defined by a communication protocol as having a group of sequential slots, the user terminal comprising:

a transceiver system to

receive a paging signal at a mobile user terminal in a sub-period of a data transfer period of a data frame as defined by the communication protocol, and

receive a repetition of the paging signal in a different sub-period of the data frame to provide different spatial signatures between the paging signal and the repetition of the paging signal,

wherein the number of repetitions is limited and selected based on estimation of proximity of the user terminal to the base station, the estimation based on data sent from the mobile user terminal to the base station in a negotiation sequence; and

a processing system in communication with the transceiver system to process the paging signal and the repetition of the paging signal to obtain paging data.

16. The user terminal of claim 15, wherein the transceiver system is to receive the paging signal in a sub-timeslot of a downlink times lot.

17. The user terminal of claim 16, wherein the transceiver system is to receive the paging signal in a half-slot of the downlink timeslot.

18. The user terminal of claim 15, wherein the transceiver system is to receive the paging signal in a sub-frequency-band of a downlink frequency band.

19. The user terminal of claim 18, wherein the transceiver system is to receive the paging signal in a frequency band one half the bandwidth of the data transfer frequency band.
