Abstract:
1. A method for allocating resources in a wireless network, the method comprising: transmitting a control channel in a resource block (RB) or RB-pair, the control channel comprising a first control channel element that is associated with a first antenna port and a second control channel element that is associated with a second antenna port, wherein the first antenna port is pre-assigned a first reference signal sequence and the second antenna port is pre-assigned a second reference signal sequence, and wherein the first reference signal sequence and the second reference signal sequence are mapped to common resource element (RE) locations in the RB or RB-pair; selecting the first reference signal sequence; and transmitting the first reference signal sequence in the RB or RB-pair without transmitting the second reference signal sequence in the RB or RB-pair, wherein the first reference signal sequence is configured to be used to perform channel estimation on both the first control channel element and the second control channel element at a receiver side.
