Embodiment Construction

[0027] The basic idea of ​​the embodiments of the present disclosure is to provide an air interface solution for integrating gigabit transmission for broadband user equipment and hundreds of bits transmission for narrowband user equipment, so as to improve system spectrum efficiency and reduce narrowband Cost and power consumption of user equipment.

[0028] Specifically, from the perspective of multiple access modes, the uplink is an SC-FDMA mechanism, the downlink for UE is an OFDM mechanism, and the downlink for narrowband user equipment is an SC-FDMA mechanism. Signals of narrowband user equipments in the downlink are transmitted through idle subcarriers reserved in OFDM, which are independent from multi-carrier subbands carrying broadband user equipment signals through FDM.

[0029] From the perspective of baseband processing, there is only a time-domain signal processing module in the narrowband user equipment, and a frequency-domain signal processing module in the base ...

Abstract

The embodiment of the invention relates to a data transmitting method and device for a base station, a data transmitting method and device for narrowband user equipment and a data receiving method and device for the narrowband user equipment. The data transmitting method for the base station comprises the steps of carrying out time domain-frequency domain transformation processing on data signals which are about to be sent to the narrowband user equipment; and carrying out orthogonal frequency division multiplexing processing on the data signals processed through time domain-frequency domain transformation processing and the data signals which are about to be sent to broadband user equipment, thereby sending the data signals. According to the scheme provided by the embodiment of the invention, only pure time domain narrowband processing is carried out at a narrowband user equipment side, so the narrowband user equipment is simplified, and the cost and power consumption are reduced. Moreover, narrowband and broadband waveform aggregation is realized, the spectrum efficiency of a whole system is improved. Due to high demands of machine type communication equipment for the cost and power consumption, the method and the device are relatively applicable to machine-to-machine communication.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of wireless communication, in particular to machine-to-machine (M2M) communication, especially to methods and devices for transmitting and receiving data between a base station and a narrowband user equipment. Background technique [0002] With the rapid popularization of smart terminals and the explosive growth of network communication capacity, the evolution requirements for the fifth generation (5G) wireless communication technology are more clear and urgent. In the evolution of wireless communication technology towards 5G, machine-to-machine (M2M) communication is considered as an essential service to be supported. [0003] With the development of the Internet of Things (IoT), IoT / M2M applications usually involve communication between machine type communication (MTC) devices such as smart sensors and smart meters and base stations (eNB, NodeB). For example, in an application scenario, the M...
