Abstract

The embodiment of the present invention provides a method and apparatus for narrowband system data transmission. The method for narrowband system data transmission of the present invention includes that: A base station takes a predetermined new resource block NRB as granularity to determine the resource blocks to be allocated to user equipment; The base station sends frequency domain resource scheduling information to the user equipment to make the user equipment determine, according to the frequency domain resource scheduling information, the frequency domain resource information of the PRB nearest to the resource blocks to be allocated and the frequency domain resource information of the NRB included in the resource blocks to be allocated and to make the user equipment transmit or receive base band signals according to the frequency domain resource information of the PRB nearest to the resource blocks to be allocated and the frequency domain resource information of the NRB included in the resource blocks to be allocated. The problem of prior art that resource allocation and dynamic allocation of frequency domain guard intervals in the narrowband system can not be realized is solved through the embodiment of the present invention.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a narrowband system data transmission method and device. Background technique [0002] In order to further improve the coverage of the existing Long Term Evolution (LTE) system, under a certain transmission power condition, the transmission time of the signal can be extended by repeated transmission in the time domain or by reducing the transmission bandwidth to achieve signal coverage. The signal-to-noise ratio is improved. The existing technology proves that the transmission efficiency of the system will be significantly reduced through repeated transmission in the time domain. In contrast, the narrowband transmission method can avoid this shortcoming. The biggest feature of the narrowband transmission is to reduce the transmission efficiency of the existing LTE system. Orthogonal Frequency Division Multiplexing (OFDM for short) subcarrier spacing, for exa...
