Title: PARTIAL BAND CONFIGURATION FOR CHANNEL STATE INFORMATION
Abstract:
Methods, systems, and devices for wireless communication are described that provide for the utilization of multiple partial bands used in the transmission of one or more channel state information (CSI) reference signals (CSI-RSs). The partial bands may be non-consecutive in the frequency domain, time domain, or a combination thereof and each of which may be precoder using a different precoder configuration. The time intervals, cycling granularity, and number of ports may vary between partial bands. Using RSs transmitted via the multiple partial bands, a user equipment (UE) may determine a channel state parameter for each partial band, which may be used for channel feedback.
