Title:
USER TERMINAL, WIRELESS BASE STATION, WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/141747
Kind Code:
A1
Abstract:
In order to avoid a reduction in uplink throughput when connecting to multiple wireless base stations, this user terminal (20), which connects to multiple wireless base stations including at least a first wireless base station and a second wireless base station, is characterized by comprising: a PH report generation unit (411) which calculates the power headroom (PH) for each wireless base station and generates a PH report; and a transmission unit (203) which transmits, to the second wireless base station, the PH report for the first wireless base station, and either the bandwidth of the physical uplink shared channel (PUSCH) of the first wireless base station, a PH report for each 1 resource block, or information relating to the transmission power density.
