ABSTRACT:
The invention relates to a method for arranging communication between terminals and an access point in a communication system applying data transmission frames. The data frames (FR) comprise timeslots for uplink and downlink communications between the terminals and the access points. The terminals can be allocated one or more timeslots in frames. The spatial signature of at least two terminals is determined, and in at least part of the frames, at least partly simultaneous timeslots are allocated to at least two terminals. Measurements are taken of a signal transmitted by the terminal and used to estimate the timing and frequency offsets and the properties of the communication channel. The simultaneous time slot allocation for terminals is done based on measurement results.
