Abstract:
1. A method of a mobile station including a receiver and a processor for determining acknowledgement/negative acknowledgement (ACK/NACK) mapped in at least two orthogonal frequency division multiplexing (OFDM) symbols, the method comprising: receiving, at the receiver, a signal comprising the ACK/NACK; determining, at the processor, an index of a first resource element group (REG) in a first OFDM symbol based on a first ratio calculated using a number of available resource element groups (REGs) in the first OFDM symbol and a number of available REGs in a second OFDM symbol, the index of the first REG corresponding to a frequency domain location; and determining, at the processor, the ACK/NACK from the signal according to the determined index of the first REG, wherein available REGs are REGs not assigned to Physical Control Format Indicator Channel (PCFICH).
