METHOD FOR CQI FEEDBACK WITHOUT SPATIAL FEEDBACK (PMI/RI) FOR TDD COORDINATED MULTI-POINT AND CARRIER AGGREGATION SCENARIOS |
摘要 |
Methods and apparatus of a base station (BS) communicating with a user equipment (UE) are provided. The BS transmits N channel state information reference signal (CSI-RS) on N CSI-RS antenna ports, which is received by the UE. A transmission mode is configured that supports coordinated multi-point (COMP) transmissions. A channel quality information (CQI) feedback configuration requires CQI feedback without a precoding matrix index (PMI) and without a rank indicator (RI). The BS receives a CQI transmitted by the UE, which is in accordance with the CQI feedback configuration. If N is one, the CQI is calculated on a single antenna port, antenna port 7, and the single antenna port is mapped from the N equals one CSI-RS antenna port. |
