Abstract:
A method, wireless device and network node for determining an indication of a precoder are provided. According to one aspect, a method in a wireless device includes determining and the indication of the precoder from a codebook, the indication comprising a first beam phase parameter and a second beam phase parameter corresponding to a first beam and a second beam respectively. The first beam phase parameter takes on one of a first integer number of phase values and the second beam phase parameter takes on one of a second integer number of phase values. At least one of the following conditions apply: the second integer number of phase values is less than the first number of phase values, and the second frequency-granularity is greater than the first frequency-granularity. The method includes transmitting the determined indication of a precoder to the network node. According to another aspect, the second beam has less power than the first beam and the second integer number of phase values is less than the first integer number of phase values.

Claim (Index 55):
The method of  claim 51 , wherein each of the first and second beams is a k th  beam, d(k), that has associated a set of complex numbers and has index pair (l k ,m k ), each element of the set of complex numbers being characterized by at least one complex phase shift such that:\n d n (k)=d i (k)\u03b1 i,n e j2\u03c0(p\u0394 1,k +q\u0394 2,k ) ; d n (k), and d i (k) are an i th  and n th  elements of d(k), respectively; \u03b1 i,n  is a real number corresponding to the i th  and n th  elements of d(k); p and q are integers; and beam directions \u0394 1,k  and \u0394 2,k  are real numbers corresponding to beams with index pair (l k , m k ) that determine complex phase shifts e j2\u03c0\u0394 1,k  and e j2\u03c0\u0394 2,k  respectively; and each of the first and second beam phase parameters is a complex coefficient c k  for d(k) used to adjust at least the phase of the i th  element of d(k) according to c k d i (k).
