Channels always deal with the slotted or cluster manner. Clustering approach provide a best frequency reuse. Each cluster contains a size to communicate i.e. 3,7,12 and some other. This channel always provides an interface, which are differing for CDMA and GSM. In GSM frequency in same cluster are different while in CDMA these frequencies are same. Based on these frequency performance varies. During these frequency allocation their might be a collision occur. This collision can either allot a channel for communication or may be generate a negative acknowledgement.
