Abstract
The invention relates to a method performed in a user equipment for estimating channel quality. The user equipment is adapted to operate in a multiple input multiple output (MIMO) mode in a communication system comprising a base station node supporting MIMO and serving the user equipment. The method comprises: receiving, from the base station node, a reference signal; performing joint demodulation of the reference signal, thereby obtaining soft values; and generating the channel quality using the soft values. The invention also relates to a user equipment, computer programs and computer program products.
