Abstract

The present invention provides a method for uplink packet scheduling, comprising the following steps: a base station determines types of terminals, and groups the terminals based on types thereof; the base station transmits pre-scheduling indication information and uplink scheduling commands to the terminals in a group with a same type; the base station receives Physical Uplink Shared Channel (PUSCH) transmitted by the terminals on a corresponding uplink sub-frame. The present invention further provides a base station and a terminal. In the above solution provided by this invention, eNB sorts accessed MTC terminals into different types of groups based on types thereof via a high-layer signaling, part of the MTC terminals in a type group are sorted into a scheduling group via a pre-scheduling instruction carried by PDSCH, all the MTC terminals in that group are scheduled via an uplink scheduling command. The solution provided by this invention can obviously reduce the number of times that the base station transmits uplink scheduling commands, and alleviate the burden on the base station of scheduling PUSCH transmission of MTC terminals.
