Abstract

Method for reservation of a medium in a radio communication network for data transmission between stations (A-E) of the network comprising at least one station (A, B, E) operating according to a first protocol (DRP) and a second station (C, D) operating according to a second protocol (802.11), the method comprises the steps of: providing a contention free period (23) within the first and second protocol; performing the reservation of the medium for the first station (A, B, E) according to the first protocol; and performing the reservation of the medium for the second station (C, D) according to the second protocol, announcing the contention free period for the first and second protocol by use of the same signal (21, 22, 31, 33). In particular a beacon signal is used, wherein the beacon includes a signal (488) which is recognized and accepted by the second stations (C, D). Further information (404) is added into the beacon frame (41) for reserving reservation periods (23) for the first stations (A, B, E).
