A user device may determine whether uplink control information and/or available channels meet certain criteria and determine whether the uplink control information should be transmitted on a physical uplink control channel, a physical uplink shared channel, or both, based on the criteria. Criteria may include the size of the uplink control information (absolute size or relative to space available on a channel or a threshold value), the type of control information bits, the number of available (i.e., active or configured) component carriers, and the amount of power that may be required to transmit the uplink control information on more than one channel. ## Claims ### Claim 1 A method for transmitting uplink control information, the method comprising: determining, by a wireless transmit/receive unit (WTRU), that the uplink control information is to be transmitted in at least a time interval, wherein the uplink control information comprises a first subset of uplink control information bits associated with a first priority and a second subset of uplink control information bits associated with a second priority, wherein the first priority is different than the second priority, wherein the first subset of uplink control information bits comprises at least a first type of uplink control information and the second subset of uplink control information bits comprises at least a second type of uplink control information, and wherein the first type of uplink control information comprises a hybrid automatic repeat request (HARQ) feedback;
