TERMINAL AND COMMUNICATION METHOD
A terminal includes a receiving unit configured to receive, from a base station, a message for requesting a report of a terminal capability, a control unit configured to include, into a message for reporting the terminal capability, a terminal capability related to measurement using a reference signal for obtaining information about a channel state, for each band or for each band combination, based on the message for requesting the report of the terminal capability, and a transmitting unit configured to transmit the message for reporting the terminal capability to the base station, wherein a range of a target time domain is specified in the terminal capability related to the measurement.
IMPROVED INTERNAL DATA TRANSFER IN A MULTIPLE-ANTENNA COMMUNICATION SYSTEM
A preprocessing arrangement is configured for installation in a multiple-antenna communication system, e.g. a MI-MO-enabled device, to improve internal data transfer of the system. The arrangement is interposed between an antenna array and a computer device. In operation, the arrangement obtains (301) a diagonal matrix W of multiplicator values, the diagonal matrix W being given by H=WAX, wherein H is a channel transmission matrix for the system, A is a predefined filter matrix, and X is a matrix that depends on H. The arrangement further extracts (302) an input vector Y of signal values from the antenna array, generates (303) an output vector Ŷ of output values by forming A.sup.HW.sup.HY, wherein superscript indicates Hermitian transpose, and provides the output values in the output vector Ŷ to the computer device. By providing the output vector Ŷ, the number of signal values to be received and jointly processed by the computer device is reduced relative to the number of antennas in the antenna array.
