Abstract:
1. A method for allocating sequences used to transmit a signal by a user equipment in a communication system, wherein the signal transmission is over a number of resource blocks in a frequency domain and over a number of symbols in a time domain, the method comprising: selecting a sub-set of sequences from a set of sequences corresponding to a first number of resource blocks, wherein the sub-set of sequences has a sub-set size that is equal to a smallest set size corresponding to a second number of resource blocks, wherein a different set of sequences exists for each possible number of resource blocks, and wherein the first number of resource blocks is different from the second number of resource blocks; and transmitting the signal in a symbol of the number of symbols and over the second number of resource blocks using only a sequence belonging to the sub-set of sequences.
