Title:
USER DEVICE AND RESOURCE SELECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/084116
Kind Code:
A1
Abstract:
Provided is a user device that selects resources for periodically sending signals, on the basis of sensing results, and has: a measurement unit that measures the reception power of a plurality of resources in past time directions, that correspond to candidate resources for sending signals; and a selection unit that selects resources for periodically sending signals, on the basis of the measurement results. The measurement unit: measures resource reception power at a first cycle in a first time window prior to a candidate resource for sending the signals; and measures the resource reception power at a second cycle longer than the first cycle, in a second time window further prior to the first time window or in the first time window and the second time window.
