Abstract

The invention discloses a scheduling information receiving method. The method comprises the following steps: acquiring downlink control information (DCI); And determining the scheduling information corresponding to the PUSCH in the DCI according to the mapping relation between the transmission configuration resources used by the physical uplink shared channel PUSCH and the scheduling information in the DCI. Compared with the prior art, the method has the advantages that the cost is low;, According to the invention, the scheduling information in the DCI is determined according to the mapping relation between the transmission configuration resources used by the UE for transmitting the PUSCH and the scheduling information in the DCI; According to the embodiment of the invention, the base station can only send one DCI (Downlink Control Information), so that the scheduling of all UE (User Equipment) with a mapping relation between the PUSCH transmission configuration resources and the scheduling information in the DCI is realized, the scheduling overhead is reduced, the resource waste is reduced, and the scheduling efficiency of the communication system on the terminal is remarkably improved.

Description

technical field

[0001] The present invention relates to the technical field of wireless communication, and more specifically, to a method and device for receiving scheduling information. Background technique

[0002] In the current MTC (Machine Type Communication, machine mode communication) technology, the system supports DCI (Downlink Control Information, downlink control information) to perform ETS (Early Termination Signal, early termination signal) scheduling for UE (User Equitment, user equipment), That is, the base station transmits the ETS signal to the UE (User Equitment, user equipment) through the DCI on the PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) to schedule the PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) time-frequency resources used by the UE . If the uplink HARQ-ACK (Hybrid Automatic Retransmission Request Acknowledgment, Hybrid Automatic Retransmission Request Acknowledgment) feedback is used to...
