Abstract: Embodiments of the present invention disclose a downlink control information (DCI) transmission method, a network device, and user equipment. The method includes the following steps: A network device transmits DCI in a first DCI format; when the DCI is used to schedule a physical downlink shared channel (PDSCH) carrying a multicast traffic channel, the network device indicates, by using a first radio network temporary identifier (RNTI), that the DCI is used to schedule the PDSCH carrying the multicast traffic channel, and that first information is indicated in the DCI and second information is not indicated in the DCI; and when the DCI is used to schedule a user equipment-specific (UE-specific) PDSCH, the network device indicates, by using a second RNTI, that the DCI is used to schedule the UE-specific PDSCH, and that the first information is not indicated in the DCI and the second information is indicated in the DCI.

Abstract: Embodiments of the present invention relate to a channel estimation method, a base station, user equipment UE, and a system. The method includes: setting up, by a base station, a connection to user equipment UE; and sending, to the UE, notification information indicating that the UE is in a radio remote scenario, where the notification information is used to instruct the UE to perform channel estimation by using a channel estimation algorithm applicable to the radio remote scenario, and the channel estimation algorithm is used to perform channel estimation on a signal that is obtained after downlink signals from multiple radio remote units RRUs are superposed. The UE can perform channel estimation by using the appropriate channel estimation algorithm, to effectively improve accuracy of the channel estimation, thereby effectively improving a downlink data throughput of the UE.

Abstract: The present disclosure discloses a communication method, an apparatus, and a system. The communication method includes: receiving, by a base station, uplink data sent by a terminal device; decoding the uplink data; and sending, by the base station, feedback information of the uplink data. The feedback information is used to indicate a decoding status of the uplink data, and carries information about an identifier. The identifier includes an identity of the terminal device or an identifier of the uplink data. In this way, the terminal device is prevented from receiving incorrect feedback information during conflicting transmission.
