15 Claims

1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

transmitting a first cyclically shifted version of a base sequence in a first resource block (RB) of an interlace of a plurality of RBs of a physical uplink control channel (PUCCH), the first cyclically shifted version of the base sequence having a first cyclic shift which is a function of an index of the first RB; and

transmitting a second cyclically shifted version of the base sequence in a second RB of the interlace, the second cyclically shifted version of the base sequence having a second cyclic shift which is a function of an index of the second RB.
