REFERENCE SIGNAL FOR A CONTROL CHANNEL IN A WIRELESS COMMUNICATION NETWORK

摘要

A wireless communication terminal receives a first set of pilot signal resource elements and control information in one or more spatial layers in a first resource block in a sub-frame and a second set of pilot signal resource elements and data in one or more spatial layers in a second resource block in the sub-frame, wherein the first and second resource blocks span a set of time symbols in a sub-frame, the first resource blocks span a first set of frequency carriers in the sub-frame, and the second resource blocks span a second set of frequency carriers in the sub-frame. The terminal decodes the one or more spatial layers in which the control information is received using the first set of pilot signal resource elements, wherein the first set of pilot signal resource elements comprises a first number of pilot signal resource elements per layer. The terminal also decodes the one or more spatial layers in which the data is received in the second resource block using the second set of pilot signal resource elements, wherein the second set of pilot signal resource elements comprises a second number of pilot signal resource elements, per layer, present in the second resource block, wherein the first number is greater than the second number.
