The radio scheduling method includes: receiving, by a terminal, a first message from a network device, where the first message indicates at least one index, each of the at least one index associated to an uplink grant resource corresponding to a logical channel; obtaining, by the terminal, a first uplink grant resource from the network device; determining, by the terminal, a first logical channel based on an index of the first uplink grant resource and the at least one index, wherein the at least one index comprises the index of the first uplink grant resource. The radio scheduling method in embodiments of this application helps ensure that the terminal selects an appropriate logical channel, thereby helping satisfy reliability requirements of different services. ## Claims ### Claim 1 A radio scheduling method, comprising: receiving, by a terminal, a first message from a network device, wherein the first message indicates at least one index, each of the at least one index associated with an uplink grant resource corresponding to a logical channel;
