INTERFERENCE LAYER CATEGORIZATION AND NON ZERO POWER INTERFERENCE MEASUREMENT RESOURCE FOR NON LINEAR PRECODING

WIPO Patent Application WO/2020/034100

A1

Methods, systems, and devices for wireless communications are described. In one aspect, the described techniques provide for identifying interference signals on multiple layers or resources and determining whether the interference signals transmitted on a particular layer or resource were precoded using linear precoding (LP) or NLP. In this aspect, a receiving device may equalize signals received from a transmitting device (e.g., filter out interference signals) based on determining whether the interference signals were precoded using a first type of precoding (e.g., linear precoding (LP) ) or a second type of precoding (e.g., NLP). In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interference resources as being precoded using LP or NLP. In this aspect, a receiving device may perform and report measurements differently for interference signals precoded using LP and interference signals precoded using NLP.
