Patent ID: 8665811

Claim:
A method in a wireless communication terminal, the method comprising: receiving a first set of pilot signal resource elements and control information in one or more spatial layers in a first set of time symbols in a first resource block in a subframe, the first resource block spanning a set of time symbols in a sub frame and a first set of frequency carriers in the sub-frame; receiving a second set of pilot signal resource elements and data in one or more spatial layers in the first set of time symbols in a second resource block in the subframe, the second resource block spanning the set of time symbols in the sub frame and a second set of frequency carriers in the sub-frame; decoding the one or more spatial layers in which the control information is received using the first set of pilot signal resource elements, the first set of pilot signal resource elements comprising a first number of pilot signal resource elements per layer; and decoding the one or more spatial layers in which the data are received in the second resource block using the second set of pilot signal resource elements, the second set of pilot signal resource elements comprising a second number of pilot signal resource elements per layer, the second number of pilot signal resource elements present in the second resource block; wherein the first number is greater than the second number; receiving a third set of pilot signal resource elements and data in one or more spatial layers in a third resource block in the subframe, the third resource block spanning a second set of time symbols in the sub-frame and the first set of frequency carriers in the sub-frame; and decoding the one or more spatial layers in which the data are received in the third resource block using the third set of pilot signal resource elements, the third set of pilot signal resource elements comprising a third number of pilot signal resource elements per layer wherein the third number is at least equal to the first number; wherein the second set of time symbols in the sub-frame is different from the first set of time symbols in the subframe.
