Abstract

The invention discloses a method, a system and a device for data transmission, which are used for realizing the technical scheme of transmitting data by adopting semi-persistent scheduling (SPS) resources in a carrier aggregation system. The data transmission method provided by the invention comprises the following steps: a base station determines the SPS resources of a plurality of member carriers reserved for the same user equipment in the carrier aggregation system in advance; and the base station carries out data transmission with the user equipment by adopting a time division multiplexing mode through the SPS resources of the plurality of the member carriers reserved for the same user equipment in the carrier aggregation system in advance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, system and device. Background technique [0002] When data is transmitted, resources carrying data need to be scheduled. Currently, there are two types of scheduling modes for transmission resources in a Long Term Evolution (LTE) system: continuous scheduling and dynamic scheduling. [0003] The so-called persistent scheduling means that the base station allocates fixed resources (time, frequency, code channel) and specifies a fixed transmission format for data packets of a certain service, and the data packets are sent in the specified resource position in the specified transmission format. The base station indicates the occurrence cycle of persistent scheduling resources through radio resource control (RRC) signaling, and specifies the frequency position and transmission format of persistent scheduling resources at the beginning of per...
