Patent ID: 8611238

Claim:
A method for transmitting Uplink Control Information (UCI) from a User Equipment (UE) to a NodeB over a Physical Uplink Control CHannel (PUCCH) during a Transmission Time Interval (TTI) including S slots in a communication system, the method comprising the steps of: transmitting the UCI using a first PUCCH format, if a number of UCI bits is less than or equal to a predetermined value; and transmitting the UCI using a second PUCCH format, if the number of UCI bits is greater than the predetermined value, wherein an s-th slot in the PUCCH includes N s1 symbols and the UCI is transmitted over N s2 symbols, with N s2 being smaller than N s1 , and wherein the UE is assigned, by the NodeB, K frequency Resource Elements (REs) and a first sequence with a length L, where K is an integer multiple Q of L, and the UE transmits Q UCI symbols in each of N s2 symbols, after multiplying each of the Q UCI symbols by the first sequence of the length L to obtain Q sequences of the length L forming a sequence of length K, mapping the sequence of a length K to the K REs, and applying an inverse Fourier transform.
