Abstract: The invention is related to signaling in cellular telecommunication systems, namely to reduction of resources used by signaling. According to the invention, a list of neighbor cell information is communicated to a mobile station in compressed form. Preferably, the neighbor cell information list is transmitted in such a way, that a table reciting parameter values in use by the neighboring cells, and for each of these cells, each value listed in the table is represented by a pointer such as an index to the table. In this way, same parameter values do not need to be repeated for each cell using the same values. The neighbor cell information list can be further compressed by expressing a first frequency parameter value in the normal way, but expressing further frequency parameter values relative to the first, or as in a further embodiment, relative to the previous frequency parameter value. Such ways of representing frequency values allow the use of fewer bits to represent the frequency values.

Abstract: A charge air cooler is provided in which, in use, the charge air enters a finned tube block at very high temperatures creating a problem in that the lamella-type corrugated fins heat up abruptly and expand in the transverse direction. In order to eliminate the resulting risks of damage, the finned tube block on the air inlet side is provided with expansion joints extending in parallel to the tubes. The expansion joints extend only to a selected depth into the finned tube block in the air flow direction, which depth is selected such that the temperature of the charge air has already dropped there to such an extent that damage as a result of thermal expansions is no longer a concern.
