1. A method comprising:
receiving, by a first transmission point from a second transmission point:
a first downlink beamforming information element associated with a first group of resources of a cell; and
a second downlink beamforming information element associated with a second group of resources of the cell, wherein second group of resources is different from the first group of resources; and
transmitting, by the first transmission point to a wireless device, signals, via the first group of resources, using a first beamforming codeword selected, from a codebook, based on the first downlink beamforming information element.
