摘要： Transmission with multiple antennas in a wireless network is performed by selecting (304) between adaptive precoding and fixed precoding based on a selection criterion. Transmission (306) using spatial multiplexing with adaptive precoding is performed if the selection criterion is fulfilled. Transmission (308) using spatial multiplexing with fixed precoding is performed if the selection criterion is unfulfilled.

摘要： In a wireless telecommunications system having plural base station (401, 402, 403) and plural mobile user equipment units (411, 412, 413), a primary serving base station transmits Physical Downlink Shared Channel (PDSCH) with zero energy (i.e., muted PDSCH) on the inter-cell CRS Resource Element (RE) location. Within the first Physical Resource Block (PRB 0), the RE positions in the frequency domain are indexed between 0 and 11. The muted PDSCH RE positions per antenna port are computed using the cell identifications (IDs) of all Coordinated Multipoint Reception (CoMP) cells other than the cell ID i. The invention defines the Orthogonal Frequency Division Multiplexing (OFDM) symbols in which muting occurs.

摘要： Channel state information (CSI) feedback in a wireless communication system is disclosed. A precoding matrix is generated for multi-antenna transmission based on precoding matrix indicator (PMI) feedback, wherein the PMI indicates a choice of precoding matrix derived from a matrix multiplication of two matrices from a first codebook W1 and a second codebook W2. In one embodiment, the first codebook W1 comprises at least a first precoding matrix PMI1 constructed with a first group of adjacent Discrete-Fourier-Transform (DFT) vectors. In another embodiment, the first codebook W1 comprises at least a second precoding matrix PMI2 constructed with a second group of uniformly distributed non-adjacent DFT vectors. In yet another embodiment, the first codebook W1 comprises at least a first precoding matrix PMI1 and a second precoding matrix PMI2, where said first precoding matrix PMI1 is constructed with a first group of adjacent DFT vectors, and said second precoding matrix PMI2 is constructed with a second group of uniformly distributed non-adjacent DFT vectors.
