Abstract

A wireless transmit/receive unit (WTRU) may receive, based on the sent location information, a proximity detection associated with another WTRU and associated with a proximity related application. A WTRU may receive scheduling information for the proximity related application and for other applications. A radio network temporary identifier (RNTI) may be utilized to identify scheduling information in relation to the proximity related application.

Claims

1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

receiving, by the WTRU from an eNodeB, a broadcasted system information block (SIB), wherein the SIB is associated with proximity related applications;

sending, by the WTRU in association with a proximity related application, location information of the WTRU to the eNodeB;

receiving, by the WTRU based on the sent location information, a proximity detection associated with another WTRU and associated with the proximity related application; and

receiving, by the WTRU, scheduling information for the proximity related application and for other applications, wherein a first radio network temporary identifier (RNTI) is utilized to identify scheduling information in relation to the proximity related application and a second RNTI is utilized to identify scheduling information in relation to the other applications.

2. The method of claim 1, wherein the scheduling information in relation to the proximity related application uses a different downlink control information format than the scheduling information in relation to the other applications.

3. The method of claim 1, wherein the scheduling information in relation to the proximity related application is for direct WTRU to WTRU communication.

4. The method of claim 1 further comprising:

transmitting discovery signals by the WTRU so that another WTRU discovers the WTRU for WTRU to WTRU communication.

5. The method of claim 1 further comprising:

registering, by the WTRU, for the proximity related application.

6. The method of claim 1 further comprising:

detecting a discover signal from another WTRU by the WTRU in an idle mode.

7. A wireless transmit/receive unit (WTRU) comprising:

a transceiver configured to receive, from an eNodeB, a broadcasted system information block (SIB) associated with proximity related applications;

a processor configured to send, to the eNodeB in association with a proximity related application, location information of the WTRU;

the transceiver further configured to receive, based on the sent location information, a proximity detection associated with another WTRU and associated with the proximity related application; and

the transceiver further configured to receive scheduling information for the proximity related application and for other applications, wherein a first radio network temporary identifier (RNTI) is utilized to identify scheduling information in relation to the proximity related application and a second RNTI is utilized to identify scheduling information in relation to the other applications.

8. The WTRU of claim 7, wherein the scheduling information in relation to the proximity related application uses a different downlink control information format than the scheduling information in relation to the other applications.

9. The WTRU of claim 7, wherein the scheduling information in relation to the proximity related application is for direct WTRU to WTRU communication.

10. The WTRU of claim 7 further comprising:

the transceiver configured to transmit discovery signals so that another WTRU discovers the WTRU for WTRU to WTRU communication.

11. The WTRU of claim 7 further comprising:

the processor configured to register for the proximity related application.

12. The WTRU of claim 7 further comprising:

the processor configured to detect a discover signal from another WTRU by the WTRU in an idle mode.

13. An eNodeB comprising:

a transmitter configured to transmit a system information block (SIB) associated with proximity related applications;

a receiver configured to receive, in association with a proximity related application, location information of a wireless transmit/receive unit (WTRU);

the transmitter is further configured to transmit, based on the received location information, a proximity detection associated with another WTRU and associated with the proximity related application; and

the transmitter is further configured to transmit scheduling information in relation to the proximity related application and for other applications, wherein a first radio network temporary identifier (RNTI) is utilized to identify scheduling information in relation to the proximity related application and a second RNTI is utilized to identify scheduling information in relation to the other applications.

14. The eNodeB of claim 13, wherein the scheduling information in relation to the proximity related application uses a different downlink control information format than the scheduling information in relation to the other applications.

15. The eNodeB of claim 13, wherein the scheduling information in relation to the proximity related application is for direct WTRU to WTRU communication.
