Method and device for downlink data transmission

Abstract

The present invention relates to the technical field of communications. Disclosed are a method and device for downlink data transmission for use in reducing network resource wastage when a network side is transmitting data to a certain group of user terminals, thus increasing network resource utilization rate. The method comprises: grouping specific user terminals into a group, and identifying each group with a unique Group ID; a user terminal, when idle, monitors paging messages intended for it, and a first message; when a network side is transmitting downlink data, the network side transmits downlink data transmission scheduling information, and pages the group of user terminals at a timing of the group by means of the first message carrying the Group ID of the group; the user terminals that have received the first message receive the downlink data at a time window and a fixed physical resource position on the basis of the group-based downlink data transmission scheduling information received. This reduces waste of network resources in M2M communications when the network side is transmitting data to a certain group of user terminals, thus increasing the effect of network resource utilization rates.
