Title: METHOD AND APPARATUS FOR SENDING CONTROL INFORMATION AND METHOD AND APPARATUS FOR RECEIVING CONTROL INFORMATION
Abstract:
Embodiments of the present application provide a method and an apparatus for sending control information. The method comprises: a network device sending first control information to a terminal device, wherein the first control information comprises first indication information and information about a first time-frequency resource, the first time-frequency resource at least carries first data, the first data comprises a first bit obtained by encoding a first information block, and the first indication information is used to indicate initial transmission or retransmission of the first information block; and the network device sending second control information to the terminal device, wherein the second control information comprises second indication information and information about a second time-frequency resource, the second time-frequency resource at least carries second data, the second data comprises a second bit obtained by encoding the first information block, and the second indication information is used to indicate that feedback information for the first information block is determined according to a result of combining and decoding the first data and the second data. Therefore, the delay in data transmission can be reduced.
