Embodiment Construction
[0041] Figure 1A is an illustration of an example communication system 100 in which one or more disclosed embodiments may be implemented. Communication system 100 may be a multiple access system that provides content, such as voice, data, video, messaging, broadcast, etc., to multiple wireless users. The communication system 100 allows multiple wireless users to access such content by sharing system resources, including wireless bandwidth. For example, the communication system 100 may use one or more channel access methods, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA) , Single Carrier FDMA (SC-FDMA) and so on.
[0042] Such as Figure 1A As shown, communication system 100 may include wireless transmit / receive units (WTRUs) 102a, 102b, 102c, 102d, radio access network (RAN) 104, core network 106, public switched telephone network (PSTN) 108, Internet 110, and Other netwo...

Abstract
Disclosed are methods and systems for transmission of uplink control information and feedback for carrier aggregation systems. The user equipment device may be configured to use one or more uplink component carriers to transmit uplink control information and other feedback for several downlink component carriers. The user equipment device may be configured to transmit these data using the physical uplink control channel instead of the physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data to transmit, the physical uplink control channel resources to transmit the uplink control information and feedback data, and how the physical uplink control channel may be to transmit uplink control information and feedback data.
