Title:
ネットワークノードへの干渉源を識別するためのユーザ機器からのアップリンク信号の生成
Document Type and Number:
Japanese Patent JP5860531
Kind Code:
B2
Abstract:
A method is disclosed that can be performed in at least one network node which provides wireless communications service for user equipment nodes (UEs). The method includes detecting uplink interference at an interfered network node. Responsive to the uplink interference, an uplink transmission having a defined configuration is initiated from a UE, which is served by a serving network node. The uplink signal is detected using the defined configuration at the interfered network node. The UE is identified responsive to the detected uplink signal as being a contributor to the uplink interference. An uplink transmission by the UE and/or by another UE served by the serving network node is controlled to reduce uplink interference.
