Abstract: A method of selecting a frequency block includes determining a first value representing a lowest noise level of a radio channel at a first or second node, calculating a first metric representing a ratio between a first desired signal strength and the first value, determining a second value representing a lowest noise level of a radio channel at the first or second nodes, calculating a second metric representing a ratio between a second desired signal strength and the second value, selecting, on the basis of at least the first and second metrics and amongst a set of frequency blocks including at least the first and second frequency blocks, a frequency block for transmission of a message between the first and second nodes, indicating a sub-band of the selected frequency block, and causing transmission of the message on the indicated sub-band.

Abstract: A method for performing link adaptation includes in a first network node of a wireless network: initializing data transmission with a second network node of the wireless network by transmitting a request-to-send message to the second network node and by receiving a clear-to-send message from the second network node, wherein the request-to-send message and the clear-to-send message are transmitted on one or more channels of the wireless network; after said initializing, generating a first data packet of the data transmission, wherein said generating comprises processing the first data packet with link adaptation parameters fixedly associated for use in connection with first data packets of data transmissions, wherein said link adaptation parameters are included in a subset of most robust link adaptation parameters supported by the first network node; receiving, from the second network node, a message indicating new link adaptation parameters for use in a subsequent data transmission; and generating a second da
