Problems solved by technology

[0009] Therefore, for an LTE network that supports MTC, when a large number of MTC terminals have uplink service requirements at the same time, using the current uplink scheduling method will easily lead to PDCCH congestion, thereby reducing the performance of the entire system and user experience

Abstract

The invention puts forward an uplink packet scheduling method. The method comprises the following steps that: a base station determines types of terminals and carries out type packet on the terminals; the base station sends pre-scheduling indication information and uplink scheduling commands to terminals in the same type packet; and the base station receives physical uplink shared channels (PUSCH) sent by the terminals at corresponding uplink subframes. In addition, the embodiment of the invention also puts forward a base station and a terminal. According to the scheme, an evolved node B (eNB) classifies accessed machine-type communications (MTC) terminals into different type packets based on types by using high-level signaling; parts of MTC terminals in the type packet are classified into one scheduling packet by using a pre-scheduling command carried by a physical downlink shared channel (PDSCH); and all MTC terminals in the packet are scheduled by using an uplink scheduling command. With the scheme, the number of times of uplink scheduling command sending by the base station can be reduced obviously; and the load of PUSCH transmission scheduling of MTC terminals by the base station is also reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, the present invention relates to a method and equipment for uplink packet scheduling. Background technique [0002] In the current LTE (Long Term Evolution, long-term evolution) technology, the PUSCH (Physical Uplink Shared Channel) transmission of the terminal is controlled by the uplink scheduling command of the eNB (evolved Node B, evolved base station). In 3GPP (the3rd Generation Partnership Project, third-generation partnership project) protocol, this uplink scheduling command is called UL Grant, that is, uplink grant, which is composed of format 0 or format 4 PDCCH (Physical Downlink Control Channel, physical downlink control channel) Bearer (except for UL Grant in random access feedback, the same below). The UL Grant will indicate to the terminal the time-frequency position of the scheduled PUSCH, MCS (Modulation and Coding Scheme, scheduling and coding...
