Claim:
A method for a physical uplink transmission, the method comprising the steps of: allocating, at a transmitter, a cyclic shift and an orthogonal cover to physical uplink control channels; remapping, at the transmitter, in a slot-level, the physical uplink control channels into two resource blocks respectively located at two slots of a subframe, with: when n s mod 2 =0, resource indices of the physical uplink control channels within a first slot of the two slots in the two slots of the subframe are established by: n ′ ⁡ ( n s ) = { n PUCCH ( 1 ) if ⁢ ⁢ n PUCCH ( 1 ) < c · N cs ( 1 ) / Δ shift PUCCH ( n PUCCH ( 1 ) - c · N cs ( 1 ) / otherwise , Δ shift PUCCH ) ⁢ mod ⁡ ( c · N sc RB / Δ shift PUCCH ) where n s is the index of slots within a subframe, n PUCCH (1) is a resource index for physical uplink control channel format 1 , 1 a and 1 b , N cs (1) is the number of cyclic shifts used for the physical uplink control channel format 1 , 1 a and 1 b in the resource block, N sc RB is the size of resource block in the frequency domain, Δ shift PUCCH ∈ { { [ 1 ] , 2 , 3 } when ⁢ ⁢ the ⁢ ⁢ cyclic ⁢ ⁢ prefix ⁢ ⁢ is ⁢ ⁢ a ⁢ ⁢ normal ⁢ ⁢ cyclic ⁢ ⁢ prefix { 2 , 3 } when ⁢ ⁢ the ⁢ ⁢ cyclic ⁢ ⁢ prefix ⁢ ⁢ is ⁢ ⁢ an ⁢ extended ⁢ ⁢ cyclic ⁢ ⁢ prefix , and ⁢ ⁢ c = { 3 for ⁢ ⁢ the ⁢ ⁢ normal ⁢ ⁢ cyclic ⁢ ⁢ prefix 2 for ⁢ ⁢ the ⁢ ⁢ extended ⁢ ⁢ cyclic ⁢ ⁢ prefix ; and when n s mod 2 =1, the resource indices of the physical uplink control channels within a second slot of the two slots of the subframe to which the physical uplink channel symbols are remapped by: n ′ ⁡ ( n s ) = f ⁢ ( n ′ ⁡ ( n s - 1 ) ) = { [ 3 ⁢ ( n ′ ⁡ ( n s - 1 ) + 1 ) ] ⁢ mod ( 3 ⁢ N sc RB / for ⁢ ⁢ normal ⁢ ⁢ cyclic ⁢ Δ shift PUCCH + 1 ) - 1 ⁢ prefix ⁢ ⁢ and ⁢ n PUCCH ( 1 ) ≥ c · N cs ( 1 ) / Δ shift PUCCH ⌊ h ⁢ ( n ′ ⁡ ( n s - 1 ) ) / c ⌋ + otherwise [ h ⁡ ( n ′ ⁡ ( n s - 1 ) ) ⁢ mod ⁢ ⁢ c ] · ( N ′ / Δ shift PUCCH ) ⁢ ⁢ where ⁢ ⁢ h ⁡ ( n ′ ⁡ ( n s - 1 ) ) = { [ 2 ⁢ n ′ ⁡ ( n s - 1 ) ] ⁢ mod ⁡ ( 2 ⁢ ⌊ d 2 ⌋ + 1 ) + for ⁢ ⁢ normal ⁢ ⁢ cyclic ⁢ ⁢ prefix d · ⌊ n ′ ⁡ ( n s - 1 ) d ⌋ · ( d ⁢ ⁢ mod ⁢ ⁢ ⁢ 2 ) n ′ ⁡ ( n s - 1 ) for ⁢ ⁢ extended ⁢ ⁢ cyclic ⁢ ⁢ prefix ⁢ ⁢ N ′ = { N cs ( 1 ) if ⁢ ⁢ n PUCCH ( 1 ) < c · N cs ( 1 ) / Δ shift PUCCH N sc RB otherwise , ⁢ and ⁢ ⁢ d = cN cs ( 1 ) / Δ shift PUCCH - 1 ; and , ⁢ transmitting, by transmitting antennas, the remapped physical uplink control channels in the physical uplink.
