Title
(EN) Method and device for sending control information and method and device for receiving control information
(ZH) 发送控制信息的方法和装置及接收控制信息的方法和装置
Abstract
(EN)
The embodiment of the invention provides a method and device for sending control information. The method comprises the steps that network equipment generates first control information for a first TB (Transport Block), wherein the first TB comprises n code block (CB) groups, n is greater than or equal to 1 and less than or equal to N, N is the maximum number of CB groups contained in the first TB,N is greater than or equal to 1, each CB group comprises at least one CB, the first control information comprises N control information fields, the N control information fields are in one-to-one correspondence with the N CB groups contained by the first TB at most, a control information field i in the N control information fields is used for indicating whether a CB group corresponding to the control information field i is about to be sent or received, and i belongs to a set [1, N]; and the network equipment sends the first control information to terminal equipment. The number of bits containedin downlink control information is enabled to be fixed, thereby reducing the blind detection complexity of the terminal equipment, reducing the processing burden of the terminal equipment, and improving the user experience.
