Title:
免許不要周波数帯における基地局ダウンリンク送信の調整方法
Document Type and Number:
Japanese Patent JP6393401
Kind Code:
B2
Abstract:
Base stations can exchange information indicating that the base stations are transmitting (or going to transmit) downlink signals over one or more unlicensed frequency bands. For example, a first indication that a first base station is reserving a first subset of a plurality of unlicensed frequency bands for downlink transmission can be transmitted over one or more interfaces between the first base station and one or more second base stations. The one or more second base stations can then refrain from transmitting potentially interfering downlink transmissions over the first subset of the plurality of unlicensed frequency bands. Information identifying the first subset may be stored by the one or more second base stations.
