<p>The present invention provides an uplink closed-loop transmit diversity system and method thereof for processing abnormality of precoding indication, the method comprising: when a terminal receives a Transmitted Precoding Indication (TPI) sent by a network side and the TPI is less than a preset threshold value, exchanging the information with the network side, or performing the uplink closed-loop transmit diversity using a preset TPI. In the present invention, when the TPIs received by the terminal are all less than the preset threshold value, exchanging the information with the network side, or performing the uplink closed-loop transmit diversity using the preset TPI, therefore, the terminal can process the needed precoding indication abnormality of transmiting when performing the uplink closed-loop transmit diversity, the realizing of the uplink closed-loop transmit diversity function can be ensured, and then the data sending can be ensured and improving the system performance.</p> |
