摘要： A method and a system for calibrating at least one antenna (1,1-1,3. 1,j). At least a first antenna (1,4) within a first antenna array (102) can be selected as a primary reference antenna. At least one antenna (4,3) that is not within the first antenna array can be selected as a secondary reference antenna. At least a first signal propagation characteristic (122) can be measured based on at least one signal wirelessly communicated between the primary reference antenna and the secondary reference antenna. At least a second signal propagation characteristic (118) can be measured based on at least one signal wirelessly communicated between the secondary reference antenna and at least a second antenna (1,2) within the first antenna array. At least a first calibration coefficient can be determined for the second antenna.

摘要： A method, apparatus and system for performing over-the-air calibration routines in a multiple-input multiple-output (MIMO) communication system. An antenna array (116) of a transceiver (118), (e.g., transceiver of a base station) (110) comprises a reconf igurable antenna (230 REF) having two switchable configuration states. The antenna exhibits different degrees of electromagnetic coupling to other antennas (230 1,..., 230 M) of the array in a first state than in a second state. The reference antennna (230 REF) is switched to the first state for performing uplink/downlink calibrating transmissions and switched to the second state during uplink and downlink communications or channel sounding calibrating transmissions.

摘要： A method of retaining channel use by a secondary system (100) is described. A secondary channel used during periods of normal communication between a secondary transmitter and receiver is split into sub-bands (A, B) for use during a quiet period containing quiet phases. During the quiet period, while the transmitter communicates with the receiver on one sub-band, the receiver simultaneously (614) senses for incumbent devices on another sub-band, as well as vice-versa. Transmission and sensing do not occur simultaneously on the same sub-band and transmission is limited to only one of the sub-bands. Transmission and sensing are performed by both the transmitter and the receiver on every sub-band over the course of the quiet period (614). The locations of secondary receivers are determined and employed during scheduling such that devices sufficiently separated from each other transmit during different quiet phases and transmit and sense in sub-bands separated by another sub-band.
