<P>PROBLEM TO BE SOLVED: To provide a method and apparatus for antenna control in a wireless terminal. <P>SOLUTION: Base stations transmit strip signals using strip signal segments and self-supporting modulation scheme techniques facilitating a rapid channel estimate. A strip segment occupies one OFDM symbol time interval and uses a set of downlink tones; some of the tones are left unused facilitating SIR measurement. Connected wireless terminals including multiple antennas used in combination, an antenna duplex module, a single RF receiver chain and a single RF transmitter chain, switch antenna coefficient combinations based on strip signal segment timing. The wireless terminal determines an independent downlink channel quality measurement. The wireless terminal compares channel quality measurements and selects an antenna coefficient combination to be used during non-strip signaling intervals obtaining very good antenna gain. <P>COPYRIGHT: (C)2012,JPO&INPIT |
