description A method for accommodating users in an uplink channel is provided. The method comprises a processor for selecting a region of sub carriers in a frequency domain, wherein a channel value of a plurality of users over the selected region varies gradually. The processor is further configured to select the sub carriers within the selected region of sub carriers by skipping the sub carriers by an integer value which is 0 or more than 0. A product of a known sequence and an exponential sequence is transmitting over the selected sub carriers, wherein the exponential sequence is characterized by a cyclic shift value. Further, a base station is configured to perform channel estimation of the users using the received selected sub carriers within the selected region and the processor is also configured to perform data detection for the users over the selected sub carriers using the estimated channel value.
