FIELD: information technology.
SUBSTANCE: multiple feedback channels can be multiplexed so that they can share bandwidth-time resources. Each feedback channel can get assigned separate subset of subcarriers in each of at least one mosaics. In each structure, user station can determine bandwidth-time resources including the first and the second part of bandwidth-time resources for the first and the second feedback channels respectively. User station can send modulation character vectors of the first length via the first feedback channel and/or modulation character vectors of the second length via the second feedback channel. Base station can receive the first and the send feedback channels and can perform detection on vectors of received characters for each feedback channel to restore signaling sent via this feedback channel.
EFFECT: higher efficiency of signaling signals transmission.
