Abstract

Provided in the embodiments of the present invention are a data transmission method, a narrowband terminal and a base station. On the one hand, in the embodiments of the present invention, the narrowband terminal is used for acquiring resource instruction information, wherein the resource instruction information is used for instructing the base station to allocate for the narrowband terminal a resource on a sub-band that can be supported by the narrowband terminal, the sub-band is a part of a system broadband that can be supported by an ordinary terminal, and the power consumption of the narrowband terminal is less than that of the ordinary terminal; and furthermore, on the basis of the resource instruction information, the sub-band and the resource on the sub-band can be determined. This allows the narrowband terminal to utilize the resource on the sub-band to transmit data with the base station on the sub-band, thus implementing, when the narrowband terminal has multiple sub-bands available, scheduling of the narrowband terminal to transmit data on at least some of the sub-bands, and solving the problem in the prior art that the base station is incapable at the current sub-band of scheduling the narrowband terminal to transmit data on other sub-bands.

Description

technical field [0001] This application relates to communication technology, in particular to a data transmission method, a narrowband terminal, and a base station. Background technique [0002] In wireless communication systems such as Long Term Evolution (LTE) system and Long Term Evolution Advanced (LTE-A) system, it supports Machine Type Communications (MTC) applications with a large number of terminals , in order to reduce the cost of the MTC terminal, it can be stipulated that the MTC terminal can only perform signaling or data processing within a small bandwidth (that is, a subband in the system broadband), so the MTC terminal can be called a narrowband terminal . In the prior art, the base station may send resource indication information to the narrowband terminal through a control channel, so as to schedule the narrowband terminal to perform data transmission in the current subband. [0003] However, when a narrowband terminal has multiple subbands, how to schedul...
