Abstract
Various communication systems may benefit from improved sounding reference symbol sounding techniques. An apparatus may comprise at least one memory comprising computer program code and at least one processor. The at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to precode at least one uplink sounding reference symbol based upon at least one initial rank indicator and at least one first vector/matrix received from a network entity. The apparatus further transforms the first vector/matrix and a second vector matrix received from the network entity into a third vector/matrix based upon a final rank indicator received from the network entity. The apparatus further transmits data based upon the third vector/matrix.
