Title:
INTERFERENCE MITIGATION FOR REMOTE DEVICES
Document Type and Number:
WIPO Patent Application WO/2020/083017
Kind Code:
A1
Abstract:
The described techniques relate to improved methods, systems, devices, and apparatuses that support interference mitigation for remote devices. A first wireless device (e.g., a base station) may detect remote interference with its communications caused by a second wireless device (e. g., a second, remote base station) based on, for example, a measured interference over thermal noise level exceeding a threshold. The first wireless device may identify a set of time-frequency resources for remote interference reference signals and a data transmission for a user equipment (UE) that is in communication with the first wireless device. The first wireless device may transmit a remote interference signal to a second wireless device (e. g., a second base station) via the set of time-frequency resources. The first wireless device may further signal a resource allocation to the UE for the UE to use for transmitting uplink transmissions to the first wireless device.
