RESOURCE SELECTION FOR DEVICE TO DEVICE DISCOVERY OR COMMUNICATION
First Claim
1. A wireless transmit receive unit (WTRU) comprising:
- a processor configured to;
determine to send information using a device-to-device transmission;
determine a reference signal receive power (RSRP) measurement of a cell associated with the WTRU;
select a resource pool from a plurality of resource pools based on the RSRP measurement of the cell, wherein each resource pool of the plurality of resource pools is associated with a range of RSRP values, and wherein the RSRP measurement of the cell is within the range of RSRP values associated with the selected resource pool; and
send the information using the selected resource pool.

Abstract
Systems, methods, and instrumentalities are disclosed to manage interference caused by D2D communications. A wireless transmit receive unit (WTRU) may include a processor. The processor may be configured to perform one or more of the following. The processor may determine to send information using a device-to-device transmission via a resource pool from a plurality of resource pools. Each resource pool may be associated with a range of reference signal receive power (RSRP) values. The processor may determine a RSRP measurement of a cell associated with the WTRU. The processor may select a resource pool from the plurality of resource pools based on the RSRP measurement of the cell. The RSRP measurement of the cell may be within the range of RSRP values associated with the selected resource pool. The processor may send the information using the selected resource pool.

17. A wireless transmit receive unit (WTRU) comprising:
a processor configured to; receive a device-to-device transmission request to send information; determine that resource selection is based on reference signal receive power (RSRP); receive a RSRP threshold associated with a resource pool out of a plurality of resource pools; determine a RSRP measurement; compare the RSRP measurement with the RSRP threshold associated with the resource pool; select the resource pool to send the information via device-to-device transmission in response to the RSRP measurement being above the RSRP threshold; and send the information using the resource pool in response to the resource pool being selected to send the information. - View Dependent Claims (18, 19, 20, 21)
