Patent ID: 11528087

Abstract:
Disclosed in the embodiments of the present invention are an information transmission method, device and system. The method comprises: generating indication information for a target terminal, the indication information is used for indicating the present state of a physical downlink control channel PDCCH of a non target terminal in a physical downlink shared channel (PDSCH) sent to the target terminal and/or the occupation state of resources of the non-target terminal; and sending the indication information to the target terminal. Thus, by means of the indication information, the terminal can learn whether a PDCCH of another terminal is present in the PDSCH sent to the terminal and/or whether there is resource occupation by the other terminal. On the basis of the content learned from the indication information, PDSCH rate matching may be implemented in order to avoid the situation of being unable to correctly analyze PDSCH data packets in a short time period due to matching errors.
