Title:
INTER-STREAM INTERFERENCE MEASUREMENT FOR NON-LINEAR PRECODING TECHNIQUES
Document Type and Number:
WIPO Patent Application WO/2022/047642
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure multiple types of resources at a user equipment (UE) for interference management processing at the UE in examples in which the base station employs a non-linear precoding technique. The multiple types of resources configured by the base station may include a first resource type configured for measuring channel gain at the UE, a second resource type configured for measuring non-linear interference at the UE arising from lower-layer data streams, and a third resource type configured for measuring linear interference at the UE arising from higher-layer data streams. The base station may transmit one or more reference signals to the UE over each of the multiple resource types and the UE may determine both a non-linear interference measurement and a linear interference measurement based on receiving the reference signals.
