Abstract
Base station uses the strip-shaped signal segments and self supporting modulation scheme techniques to transmit with like signal in order to carry out rapid channel estimate. The first strip-shaped segment occupies one OFDM symbol time interval and uses a set of downlink frequency in the frequency of some e.g. half are left not used for SIR measurement. Strip-shaped segment preferably is timed to connected wireless terminals do not typically transmit uplink in the uplink signal at intervals are corresponding to each other. Connecting the wireless terminal comprising: a plurality of antenna an antenna duplex module is used in combination single RF receiver chain and single RF transmitter chain switch antenna coefficient combinations based on strip signal segment timing. The wireless terminal determines an independent downlink channel quality measurement for each strip signal segment and for on-going non-carried out in strip-shaped signal such as SNR and/or SIR. The wireless terminal compares channel quality measurements and selects an each to be used in the non-strip signal intervals to obtain very good antenna coefficient combination of antenna gain.
Base stations transmit strip signals using strip signal segments and self supporting modulation scheme techniques facilitating rapid channel estimate. A strip segment occupies one OFDM symbol time interval and uses a set of downlink tones; some e.g. half of the tones are left unused facilitating SIR measurement. The strip segments are advantageously timed to correspond to uplink access intervals in which connected wireless terminals do not typically transmit uplink signals. Connected wireless terminals including: multiple antennas used in combination an antenna duplex module single RF receiver chain and single RF transmitter chain switch antenna coefficient combinations based on strip signal segment timing. The wireless terminal determines an independent downlink channel quality measurement e.g. SNR and/or SIR for each strip signal segment and for on-going non-strip signaling. 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.
