摘要： An antenna apparatus operates as a base station in a wireless network with spatial nulling performed within such apparatus. The apparatus has an antenna assembly employing a selected reception beam pattern. During a nulling test, a reception beam pattern controller causes the assembly to employ each reception beam pattern. Quality metric determination circuitry determines for each reception beam pattern a link quality metric for each of several wireless terminals, based on communication between those wireless terminals and the base station whilst the assembly employs that reception beam pattern. Reception beam determination circuitry determines, from the various link quality metrics, a reception beam pattern from the reception beam patterns for use for subsequent communication with the wireless terminals. A reception beam pattern can be altered seeking to reduce interference source effects and to maintain an appropriate level of link quality regarding each wireless terminal communicating with the base station.

摘要： A method and system are provided for determining modulation control information and a reference signal design to be used by a transmitter node when generating a transmit signal to transmit from a transmitter (logical antenna) of the transmitter node over a channel of a wireless link to a recipient node. The modulation control information is used by the transmitter node to convert source data into an information bearing signal, and the information bearing signal is combined with a reference signal conforming to the reference signal design in order to produce the transmit signal. The method comprises (a) selecting a candidate reference signal design from a plurality of candidate reference signal designs, (b) determining channel state information for the channel, (c) determining, from the channel state information, signal to noise ratio information for said channel, and (d) for each of a plurality of candidate modulation control information, using the signal to noise ratio information to determine a quality indication for said channel. Steps (a) to (d) are then repeated for each candidate reference signal design in said plurality. Thereafter a winning quality indication is selected from the determined quality indications, and the combination of candidate reference signal design and candidate modulation control information associated with the winning quality indication is then output to the transmitting node. By such an approach, quality indications can be established for each combination of possible reference signal design and possible modulation control information, and hence not only is the inherent channel estimation accuracy achievable using each possible reference signal design considered, but also the data transmission efficiency and robustness to channel effects of each possible modulation control information is also taken into account.
