摘要： A system is provided for precoding in a coordinated multipoint (CoMP) joint transmission (JT) system. During operation, the system identifies, at a first base station (BS) of a first cell, a set of regular user equipments (UEs), which are located within the first cell and receive signals from the first BS; and one or more coordinated multipoint (CoMP) UEs, which are located within a second cell and receive signals. The CoMP UEs receive signals from both the first BS and a second BS of the second cell. The system obtains a first channel state information (CSI) associated with the regular UEs, receives a second CSI associated with the CoMP UEs from the second BS, and constructs a local precoder for the first cell in accordance with the first CSI and the second CSI.

摘要： In order to minimize the control signaling overhead associated with transmitting CQI data from mobile stations to base stations in wireless communication networks supporting MU-MIMO, the CQI during MU-MIMO operation is estimated based on SU-MIMO CQI data, mobile station geometry data, and mobile station PMI (Precoding Matrix Index) data. More particularly, the base station maintains and updates a knowledge pool that correlates geometry data and learned impact of interfering precoder data to degradation of CQI values responsive to switching from SU-MIMO operation to MU-MIMO operations. Then, when the base station switches from SU-MIMO operation to MU-MIMO operation, it consults the knowledge pool to predict the degradation in CQI and subtracts them from the known, pre-switching SU-MIMO CQI feedback data for each relevant mobile station to predict the post-switching MU-MIMO CQIs for that mobile station.
