Non-zero power interference measurement resource and interference layer categorization for nonlinear precoding

摘要

Methods, systems, and devices for wireless communications are described. In an aspect, the described techniques identify interfering signals on multiple layers or resources, and determine whether interfering signals transmitted on a specific layer or resource are precoded using linear precoding (LP) or NLP. Provides what to decide. In this aspect, the receiving device determines whether the interfering signals have been precoded using a first type of precoding (e.g., linear precoding (LP)) or a second type of precoding (e.g., NLP). Based on that, it is possible to equalize (eg, filter out interfering signals) signals received from the transmitting device. In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interfering resources as being precoded using LP or NLP. In this aspect, the receiving device may perform and report measurements differently for interfering signals precoded using LP and interfering signals precoded using NLP.
