APERIODIC SOUNDING REFERENCE SYMBOL CONFIGURATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An aperiodic sounding reference symbol configuration in a wireless communication system is provided to rapidly process data by preventing setting parameters which are not used from being transmitted. CONSTITUTION: A UL(up link) transmission mode is set as a mode 1(602). The UL transmission mode is set as a mode 2. An aperiodic SRS for a DCI(downlink control information) format 0/1a is set(604). Aperiodic SRS parameter sets for a DCI format 4 are set(606). The aperiodic SRS parameter sets for the DCI format 4are not set. The setting method is performed in a network terminal device or a user device. [Reference numerals] (602) Setting of an UL transmission mode to be equal to 1; (604) Setting of an aperiodic SRS for DCI format 0/1a; (606) Aperiodic SRS parameter sets for the DCI format 4 are not set; (AA) Start; (BB) End
