| Zusammenfassung: | PROBLEM TO BE SOLVED: To improve frequency utilization efficiency while considering interference with an adjacent system by determining transmission power or resource block when a user device transmits an incoming signal using a relationship between transmission power and an available resource block.SOLUTION: The user device in a radio communication system having a base station and the user device includes: a transmission power determination unit for determining maximum allowable transmission power on the basis of an available resource block as well as transmission power from the maximum allowable transmission power; and a transmission unit for transmitting an incoming signal by the determined transmission power.SELECTED DRAWING: Figure 4
【課題】送信電力と使用可能なリソースブロックとの関係を用いてユーザ装置が上り信号を送信するときの送信電力又はリソースブロックを決定することにより、隣接システムへの干渉を考慮しつつ周波数利用効率を向上させる。【解決手段】基地局とユーザ装置とを有する無線通信システムにおけるユーザ装置は、使用可能なリソースブロックに基づいて、最大許容送信電力を決定し、前記最大許容送信電力から送信電力を決定する送信電力決定部と、前記決定された送信電力で上り信号を送信する送信部とを有する。【選択図】図４ |
