METHOD AND DEVICE FOR TRANSMITTING DOWNLINK CONTROL INFORMATION, METHOD AND DEVICE FOR RECEIVING DOWNLINK CONTROL INFORMATION, TERMINAL, BASE STATION AND COMMUNICATION SYSTEM

摘要

The present invention relates to a method and a device for transmitting downlink control information, a method and a device for receiving downlink control information and a terminal, a base station and a communication system which includes the terminal and the base station. The Resource Indication Values (RIVs) in the Downlink Control Information (DCI) are set to different values based on the function of the DCI to be transmitted according to the embodiment provided, wherein the different scopes of values are corresponding to the different functions of DCI. The different functions may be used as the configuration signaling of Sounding Reference Signal (SRS), or used as the scheduling signaling of Physical Uplink Shared Channel (PUSCH). The embodiment provided can distinguish the different downlink control information with the same length using the Resource Indication Value (RIV) in the Downlink Control Information (DCI).
