METHODS AND APPARATUSES FOR SENDING AND RECEIVING CONTROL INFORMATION |
(57) The present invention provides a method for sending and receiving control information,
an apparatus and a communication system. The method for sending control information
includes: setting respective control bits in a downlink control information (DCI)
format to generate control information applied by a network side to a terminal, where
the control bits include validity indication bits and transmission control bits, indication
information indicating whether transmission control exercised by the network side
on a transmission block is valid relative to the terminal is written into the validity
indication bits, and the validity indication bits are located outside the transmission
control bits; and sending the generated control information to the terminal. In the
embodiments of the present invention, a network side device extends or changes functions
of some control bits in the DCI format of the control information, so as to improve
efficiency of using a resource overhead occupied by the control bits in the DCI format
of the control information, and improve efficiency of using an overhead required for
transmitting the control information.
