Abstract
A system and method for identifying a resource region including a plurality of symbols, allocating pilot signals to the resource region, identifying pilot-free symbols free of the pilot signals in the plurality of symbols, arranging sacrifice carriers for a first region of a group of symbols in the pilot-free symbols at a first density for a first communication station, and arranging sacrifice carriers for a second region of the group of symbols in the pilot-free symbols at a second density for a second communication station, the first communication station mobile with respect to an access communication station at a first relative speed and the second communication station is mobile with respect to the access communication station at a second relative speed, and wherein the first density of sacrifice carriers is greater than the second density of sacrifice carriers if the first relative speed is greater than the second relative speed.
