摘要： Disclosed herein are systems and methods for long-term feedback transmitting and rank reporting. According to an aspect, a method of feedback reporting may be implemented at a WTRU. The method may include determining a long-term precoder and a short-term precoder. The method may also include calculating channel quality index (CQI) based on the long-term precoder and the short-term precoder. Further, the method may include transmitting the CQI to a base station.

摘要： Embodiments contemplate methods and systems for determining and communicating channel state information (CSI) for one or more transmission points (or CSI reference signal resources). Embodiments further contemplate that the one or more transmission points may be associated with one or more non-zero power CSI reference signal resources corresponding to one or more CSI reference signal resource configurations.
