Abstract
The present invention discloses a method for allocating an uplink sounding region dynamically to obtain downlink channel quality information (CQI) about a downlink channel. The method comprises receiving a downlink transmission request and retrieving an identification information from the downlink transmission request, searching one or more databases using the retrieved identification information as a key, identifying the CQI about the downlink channel from the one or more databases, wherein the uplink sounding region needs not to be allocated when the CQI corresponding to the downlink transmission request is identified in the databases.
