Abstract: A resource determining method and an apparatus are disclosed. A network device determines a resource of an uplink channel. A terminal device receives downlink control information (DCI) sent by the network device, where the DCI is carried on a physical downlink control channel (PDCCH). The terminal device determines the resource of the uplink channel based on the DCI, where the resource of the uplink channel is used to send uplink information. As a result, a latency of sending the uplink information is reduced.

Abstract: This application provides a downlink channel transmission method and apparatus, so that reliability of downlink channel transmission can be improved. The method includes: A terminal device receives at least two physical downlink control channels PDCCHs on at least two control information resources, where the at least two PDCCHs carry same downlink control information DCI, and the DCI is used to indicate a time-frequency resource corresponding to a first downlink channel. The terminal device obtains at least two transmission configuration indicators TCIs corresponding to the at least two control information resources. The terminal device determines a target TCI in the at least two TCIs, where the target TCI is a TCI corresponding to the first downlink channel. The terminal device receives the first downlink channel based on the DCI and the target TCI.

Abstract: The present disclosure relates to a terminal device, in which a processing module selects one or more normal carriers or special carriers from a first carrier set for an uplink subframe, where the first carrier set includes all carriers in carrier aggregation that are used by the terminal device to send a first uplink subframe; and a sending module cancels sending of the uplink subframe on one or more carriers, where the special carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink, and the normal carrier is a carrier that is used by the terminal device to send uplink data and/or uplink control information. An uplink subframe on some carriers is rejected, thereby resolving a problem that information such as a downlink channel characteristic of a carrier cannot be obtained when no uplink reference signal is sent on the carrier.
