FIELD: information technology.
SUBSTANCE: signals can be spread within contiguous channel clusters in a range element where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassignment value, which allows devices to utilise persistent channels in communicating data to one another, which is the technical result.
EFFECT: easy acknowledgement channel establishment for direct communication line and transmitting acknowledgement signals over the said channel.
