Abstract: This application provides one or more resource indication methods, terminal devices, and network devices. An example method includes: receiving, by the terminal device, the first indication information, and determining time domain positions of a demodulation reference signal (DMRS) based on the mapping type of the physical shared channel and with reference to a position index of the last symbol occupied by the physical shared channel or a quantity of symbols occupied by the physical shared channel in the resource unit. The position index of the last symbol occupied by the physical shared channel in the resource unit corresponds to the first type, and the quantity of symbols occupied by the physical shared channel in the resource unit corresponds to the second type.

Abstract: A method for indicating downlink control signaling and a related device are provided. The method includes: generating, by an access network device, indication information, and sending the indication information to a first terminal device by using downlink control signaling, where the indication information is used by the first terminal device to obtain information about an antenna port that is used by a second terminal device and that is corresponding to a demodulation reference signal, and the second terminal device is a terminal device currently performing spatial multiplexing together with the first terminal device. This implements interference detection performed by the first terminal device on a plurality of users.

Abstract: A packet transmission method, packet transmission apparatus, and an interconnect interface are presented, where the method includes determining, by a sending node, whether an unrecoverable failure occurs in an active link, and if an unrecoverable failure occurs in the active link, selecting, from multiple communication links, at least one standby link except the active link to send a packet to a receiving node, so that the receiving node sends the packet to a receive end of the active link. In the method, for two nodes in an interconnect system that communicate with each other using multiple Links, when it is determined that an unrecoverable failure occurs in some of the Links, packets in retransmission buffers of transmit ends of the links in which the failure is unrecoverable are sent to a standby link.
