Abstract: The Orthogonal Frequency Division Multiple Access OFDMA and Orthogonal Frequency Division Multiplexing OFDM techniques involve transmitting so called map messages in order to inform user terminals which slots are allocated to them. The large size of the map messages may constitute a problem in the system, and thus the present solution intends to alleviate this problem. The idea is to use semi-static allocation maps, wherein a location, size, and modulation and coding method of allocated slots are predefined for a connection. Then, the present solution allows defining validity information indicating which of the predefined allocations are to be used for a current frame.

In order to enhance the accuracy and reliability of estimates of transmission times or of changes of the transmission time of signals transmitted by radio transmitters BTS, it is proposed that a difference in the time level of estimates of the transmission times based on the measurement results of two different radio receivers LMU A,B is taken into account in a filtering of the estimates for obtaining an accurate value for the transmission times. It is further proposed that the changes of the transmission times estimated at different receivers LMU A,B is averaged for obtaining an accurate information about the changes. The invention equally relates to a corresponding radio communications system and to a processing unit for such a system.
