Abstract

The embodiment of the invention discloses a method for transmitting control information and a communication device, which are used for enabling network equipment and user equipment to have consistent understanding on the size of the control information and avoiding blind detection of a user so as to improve the service reliability. The method comprises: transmitting target control information, the target control information comprising resource indication information, the number of bits of the target control information being related to the number of bits of the resource indication information.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and communication device for transmitting control information. Background technique [0002] What is transmitted on the control channel is control information related to the shared channel, such as downlink control information (Downlink Control Information, DCI), and the control information carries resource indication information to indicate resource allocation. Only when the terminal correctly decodes the control information can it obtain corresponding shared channel data, such as physical downlink shared channel (Physical downlink shared channel, PDSCH) data or physical uplink shared channel (Physical uplink shared channel, PUSCH) data. [0003] In the case of multiple resource pools, different resource pool configurations may be different, for example, the number of sub-channels (sub-channel) and / or the maximum number of resources (N_max) may b...
