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.
