ABSTRACT:
The specification and drawings present a new method, system, apparatus and software product for locating synchronization channels (SCH) in a downlink which are received by a user equipment (UE), such that the downlink synchronization channels are transparent to shared channel users (or UE) which can be used, e.g., in evolving and future systems such as EUTRAN, 4G, 3GPP2, etc. The synchronization channels are arranged so that they are transparent to the UE in a normal active operation state. For that, the resources given to the SCH are chosen to be one or more allocatable resources (resource units) in a sub-frame or in a plurality of sub-frames. In an allocation table, these resources may not be allocated to the UE and in the active state the UE sees that and discards these resources just as it discards any other resource that is not allocated to it.
