A fast method for allocating those channels or subcarriers of a multicarrier network to an ahead lying transmission is to let a transmitting terminal and a receiving terminal which intend to access the medium determine the status of the channels or subcarriers that are within their reception range and send a signal indicating the determined status to the corresponding terminal which will select those channels or subcarriers for the eventual transmission which fit best. Other terminals within the transmission range of the transmitting or the receiving terminal respect the reservation and wait for the current transmission to find out which channels or subcarriers are actually used.

Method for signaling the status of a subcarrier in a MC network and a method for adaptively allocating the subcarriers in a MC network

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 () 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 (). In particular a beacon signal is used, wherein the beacon includes a signal () which is recognized and accepted by the second stations (C, D). Further information () is added into the beacon frame () for reserving reservation periods () for the first stations (A, B, E).

Method of distributive reservation of a medium in a radio communications network

A method of operating a network node of a network, a network node, a network system, a computer-readable medium, and a program element A method () of operating a network node (-) of a network system (), comprising the steps of generating () a signal to be transmitted, selecting () one of a plurality of communication channels (-) of the network system () for transmitting the signal, and, in case that the selected channel (-) is not ready for transmitting the signal, selecting () another one of the plurality of communication channels (-) for transmitting the signal.
