Abstract

A terminal apparatus for communicating with a first terminal apparatus and a second terminal apparatus is responsible to relay communication between the first terminal apparatus and the second terminal apparatus. The terminal apparatus measures a sidelink Reference Signal Received Power (SL-RSRP) in each of communication with the first terminal apparatus and communication with the second terminal apparatus, and determines whether the two SL-RSRPs are equal to or greater than a threshold and notifies the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity in a case that the two SL-RSRPs are determined to be equal to or greater than the threshold, and does not notify the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity in a case that the two SL-RSRPs are not determined to be equal to or greater than the threshold.

Claims (10)

1. A third terminal apparatus for communicating with a first terminal apparatus and a second terminal apparatus, the third terminal apparatus being responsible to relay communication between the first terminal apparatus and the second terminal apparatus, the third terminal apparatus comprising:

a processing unit configured to measure a sidelink Reference Signal Received Power (SL-RSRP) in each of communication with the first terminal apparatus and communication with the second terminal apparatus; and

a transmitter, wherein

the processing unit determines whether the two SL-RSRPs are equal to or greater than a threshold, and notifies the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity to each other in a case that the two SL-RSRPs are determined to be equal to or greater than the threshold, and does not notify the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity to each other in a case that the two SL-RSRPs are not determined to be equal to or greater than the threshold.

2. A method for a third terminal apparatus for communicating with a first terminal apparatus and a second terminal apparatus, the third terminal apparatus being responsible to relay communication between the first terminal apparatus and the second terminal apparatus, the method comprising:

measuring a sidelink Reference Signal Received Power (SL-RSRP) in each of communication with the first terminal apparatus and communication with the second terminal apparatus; and

determining whether the two SL-RSRPs are equal to or greater than a threshold, and notifying the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity to each other in a case that the two SL-RSRPs are determined to be equal to or greater than the threshold, and not notifying the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity to each other in a case that the two SL-RSRPs are not determined to be equal to or greater than the threshold.

3. An integrated circuit mounted on a third terminal apparatus for communicating with a first terminal apparatus and a second terminal apparatus, the third terminal apparatus being responsible to relay communication between the first terminal apparatus and the second terminal apparatus, the integrated circuit performing:

measuring a sidelink Reference Signal Received Power (SL-RSRP) in each of communication with the first terminal apparatus and communication with the second terminal apparatus; and

determining whether the two SL-RSRPs are equal to or greater than a threshold, and notifying the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity to each other in a case that the two SL-RSRPs are determined to be equal to or greater than the threshold, and not notifying the first terminal apparatus that the first terminal apparatus and the second terminal apparatus are in proximity to each other in a case that the two SL-RSRPs are not determined to be equal to or greater than the threshold.
