摘要： A first precoding matrix W1 is selected from a first codebook comprising sets of rank specific precoding matrices. The first codebook is characterized by there being fewer precoding matrices associated with higher ranks than associated with lower ranks, and characterized by precoding matrices associated with ranks above a certain rank all being diagonal matrices. The selected first precoding matrix W1 is used to select a rank-specific second precoding matrix W2 from a second codebook, such that the selected first and second precoding matrices form a joint precoder specific to a desired rank. The second codebook is characterized by differently sized precoding matrices associated with each of N total ranks, in which N is an integer greater than one. Information on the joint precoder is reported to a network node over an uplink transmission channel.

摘要： In an embodiment, state of a wireless channel on which information is received is measured; the measured state is used to select from a codebook a plurality of N codewords which optimize a predefined measure, and first and second codewords of the plurality are reported which best optimizes and next-best optimizes the predefined measure. If by example the above is done by a user equipment UE, in another embodiment the network receives first and second indications, searches a codebook using the first and second indications to find the first and second codewords; and utilizes them to improve the channel state information, such as by interpolatingbetween them to find an estimate ofthe channel. In examples the channel is a MIMO channel that is estimated at two or more antenna ports, there are interpolation weights sent with the codeword indications,and the interpolating uses a geodesic algorithm.
