摘要
The invention relates to a method in a wireless data transmission system (1) which comprises wireless terminals (MT1-MT4), at least a first access point (AP1) and a first access point controller (AC1), a second access point (AP2) and a second access point controller (AC2). In the data transmission, data frames are used. In the invention, two allocation strategies are defined of which two are selected at a time. From the data frames, a first starting point (TS11, TS21) and a second starting point (TS1n, TS2n) are determined. In order to select a strategy, it is examined whether there is other traffic on the channel. If other traffic can be detected, it is examined which allocation strategy is selected, and an allocation strategy which is different from that of the examined connection is selected for the connection to be set up. However, if traffic is not detected, it is possible to select the allocation strategy freely. In the first allocation strategy, the allocation of the time slots of the data field (D1, D2) is started from the first starting point (TS11, TS21) of the data field, and in the second allocation strategy, the allocation of the time slots of the data field is started from the second starting point (TS1n, TS2n) of the data field.
