  • Reference signal for a control channel in wireless communication network
    Patent number: 8665811
    Abstract: A wireless communication terminal receives a first set of pilot signal resource elements and control information in spatial layers in a first resource block in a subframe and a second set of pilot signal resource elements and data in spatial layers in a second resource block in the subframe, 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 spatial layers in which the control information is received using the first set of pilot signal resource elements. The terminal also decodes the spatial layers in which the data are received in the second resource block using the second set of pilot signal resource elements.

  • REFERENCE SIGNAL FOR A CONTROL CHANNEL IN WIRELESS COMMUNICATION NETWORK
    Publication number: 20130044692
    Abstract: 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 subframe and a second set of pilot signal resource elements and data in one or more spatial layers in a second resource block in the subframe, 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.
