METHOD AND APPARATUS FOR MAPPING AN UPLINK CONTROL CHANNEL TO A PHYSICAL CHANNEL IN A SINGLE CARRIER FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM
First Claim
1. In a wireless communication system where single carrier frequency division multiple access (SC-FDMA) is used for uplink transmission from a wireless transmit/receive unit (WTRU) to a Node-B, a method for mapping an uplink control channel to a physical channel, the method comprising:
- generating control bits to be carried by at least one control channel; and
mapping the control channel to a plurality of subcarriers among subcarriers in a resource block assigned to a WTRU and to at least one long block (LB) in a sub-frame.

Abstract
A method and apparatus for mapping an uplink control channel to a physical channel in a single carrier frequency division multiple access (SC-FDMA) system are disclosed. A wireless transmit/receive unit (WTRU) generates control bits to be carried by a control channel. The WTRU maps the control channel to a plurality of subcarriers among subcarriers in a resource block assigned to the WTRU and to at least one long block (LB) in a sub-frame. The control channel includes a data-non-associated control channel and/or a data-associated control channel. The subcarriers mapped to the data-non-associated control channel may be distributed over all, or a fraction of, at least one resource block. The data-non-associated control channel may be mapped to the subcarriers with one or more subcarriers as a basic unit. The mapped subcarriers may be consecutive in frequency domain. The control bits may be multiplexed with data bits within the LB.
