Abstract
A reception method implemented by a reception device implementing a plurality of receive antennas. The method includes: estimating an interference covariance matrix representative of the spatial structure of the interference between the receive antennas; and transmitting at least one item of information about a quality of service associated with at least one acquisition technique for acquiring knowledge of the channel at transmission, able to be used by a transmission device implementing a plurality of transmit antennas, obtained from the interference covariance matrix.
Claims16
A reception method implemented by a reception device implementing a plurality of receive antennas, comprising:
- estimating an interference covariance matrix, representative of a spatial structure of interference between the receive antennas;
- and
- transmitting at least one information item about quality of service associated with at least one technique for acquiring Channel State Information, that can be used by a transmission device implementing a plurality of transmit antennas, obtained from said interference covariance matrix.
A transmission method implemented by a transmission device implementing a plurality of transmit antennas, wherein the transmission method comprises:
- receiving at least one information item about quality of service associated with at least one technique for acquiring Channel State Information that can be used by said transmission device, obtained from an interference covariance matrix, representative of a spatial structure of interference between a plurality of receive antennas of a reception device,
- implementing a technique for acquiring the Channel State Information identified from said at least one information item.
A reception device comprising:
- a plurality of receive antennas;
- at least one processor;
- and
- at least one non-transitory computer readable medium comprising instructions stored thereon which when executed by the at least one processor configure the reception device to:
- estimate an interference covariance matrix, representative of a spatial structure of interference between the receive antennas,
- transmit at least one information item about quality of service associated with at least one technique for acquiring Channel State Information that can be used by a transmission device implementing a plurality of transmit antennas, obtained from said interference covariance matrix.
