One of the first interface and the second interface may utilize the Internet Protocol. One of the first interface and the second interface may be a non-cellular interface and the other interface may be a cellular interface. The femtocell may be operable to generate a timestamp corresponding to a time instant at which a time-stamped packet arrived via the first interface or the second interface. The timestamp may be referenced to a clock within a cellular enabled communication devices communicatively coupled to the femtocell.

摘要： Channel state information in a multiple-input multiple-output (MIMO) pre-coding system is quantized onto a codebook, which comprises one or more unitary matrices, using a cost function. Voronoi regions are computed from the codebook. The codebook may be updated based on the computed Voronoi regions. The channel state information may comprise a matrix V. The cost function f(A) is defined by the following relationship: f ⁡ ( A ) = ( 1 N ⁢ ∑ j = 1 N ⁢  a jj  2 ) where A is a matrix of size N by N and aij is element (i,j) of matrix A. Voronoi regions may be generated from the codebook for the unitary matrices. A set of matrices based on the Voronoi regions and the unitary matrices may be generated. Updating the codebook may be achieved by modifying the set of matrices into a new set of unitary matrices, where the new set of unitary matrices become the codebook.
