Title:
USER TERMINAL, WIRELESS BASE STATION, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/115284
Kind Code:
A1
Abstract:
When the PUCCH and inter-terminal discovery signal are frequency-division multiplexed, interference (in-band leakage) by the inter-terminal discovery signal with respect to the PUCCH is decreased. A user terminal according to the present invention transmits the PUCCH and a inter-terminal discovery signal by frequency-division multiplexing. The user terminal of the present invention is provided with: a reception unit that receives, from a wireless base station, limited resource region information indicating a limited resource region apart from an adjacent region to a frequency resource region in which the PUCCH is located; a determination unit that determines a distance between the wireless base station and the user terminal; and a selection unit that selects a resource for locating the inter-terminal discovery signal from the limited resource region when it is determined by the determination unit that the distance is relatively small.
