The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of a data transmission method of a narrowband system according to Embodiment 1 of the present invention. The method in this embodiment is applicable to a situation in which a user equipment (User Equipment, UE for short) obtains a frequency domain resource allocated by a base station, and sends or receives a baseband signal according to the acquired frequency domain resource information. The method is performed by a narrowband system data transmission device, which is typically implemented in hardware and/or software. The method of this embodiment includes the following steps:

110. The base station determines, according to the predefined NRB, a resource block to be allocated allocated to the user equipment.

The base station sends the frequency domain resource scheduling information to the user equipment, so that the user equipment determines, according to the frequency domain resource scheduling information, the frequency domain resource information of the PRB that is closest to the resource block to be allocated, and the frequency domain resource of the NRB included in the resource block to be allocated. And transmitting, by the user equipment, the baseband signal according to the frequency domain resource information of the PRB closest to the resource block to be allocated and the frequency domain resource information of the NRB included in the resource block to be allocated.

In a narrowband system, in order to maintain the backward compatibility of the system, it is necessary to set the guard interval of the frequency domain resources to avoid interference between subcarriers caused by different subcarrier spacings in the system and other non-ideal factors. However, The introduction of the guard interval may affect the user equipment to identify the resources allocated by the base station for the user equipment. The existing guard interval is set in a recessive manner, that is, within a certain allocated resource, a fixed number of idle subcarriers are used as guard bands, such as a random access channel and a synchronization channel, and user equipment. The frequency domain resource allocated by the base station can be obtained in the implicit manner. However, in a narrowband system, the frequency domain bandwidth of the subcarriers and the frequency domain bandwidth of the required guard interval are not equal. If the implicit mode is adopted, the user equipment cannot obtain the resources allocated by the base station. This embodiment is based on a narrowband system, due to the subcarrier The frequency domain bandwidth of the wave and the frequency domain bandwidth of the required guard interval are not equal, so that the user equipment cannot obtain the frequency domain resource allocated by the base station for consideration, and the granularity is defined by a predefined new resource block (NRB). Determining the resource block to be allocated allocated to the user equipment, and transmitting the frequency domain resource scheduling information to the user equipment, so that the user equipment determines the frequency domain resource information of the NRB included in the resource block to be allocated according to the frequency domain resource scheduling information, and makes the user equipment The baseband signal is transmitted or received according to the frequency domain resource information of the physical resource block (Physical Resource Block, PRB) that is closest to the resource block to be allocated and the frequency domain resource information of the NRB included in the resource block to be allocated. Therefore, in a case where the frequency domain bandwidths of the subcarrier spacing and the guard interval in the narrowband system are not equal, the user equipment cannot acquire the resources allocated by the base station, and the data is transmitted according to the resources allocated by the base station.

Specifically, the base station determines, according to the predefined NRB, the resource block to be allocated allocated to the user equipment, and sends the frequency domain resource scheduling information to the user equipment, so that the user equipment determines, according to the frequency domain resource scheduling information, the resource block to be allocated. The frequency domain resource information of the NRB, and the user equipment sends or receives the baseband signal according to the frequency domain resource information of the PRB closest to the resource block to be allocated and the frequency domain resource information of the NRB included in the resource block to be allocated.

In the data transmission method of the narrowband system provided by the embodiment, the base station determines the resource block to be allocated allocated to the user equipment by using the predefined NRB as the granularity, and sends the frequency domain resource scheduling information to the user equipment, so that the user equipment is based on the frequency domain resource. The scheduling information determines the frequency domain resource information of the PRB that is closest to the resource block to be allocated and the frequency domain resource information of the NRB included in the resource block to be allocated, and causes the user equipment to use the frequency domain resource information of the PRB closest to the resource block to be allocated. And the frequency domain resource information of the NRB included in the resource block to be allocated, transmitting or receiving the baseband signal. Therefore, the problem of resource allocation in the narrowband system and the dynamic allocation of the frequency domain guard interval cannot be realized in the prior art, and the interference caused by the introduction of different subcarrier spacing is avoided under the premise of realizing efficient use of resources, and If the sub-band spacing and the guard-band's frequency domain bandwidth are not equal in size, less signaling can be used to instruct the user equipment to acquire the resources allocated to the base station and transmit or receive the baseband signal according to the resources allocated thereto.

2A is a flowchart of a data transmission method of a narrowband system according to Embodiment 2 of the present invention. Referring to FIG. 2A, the method of this embodiment may include:

As shown in 2B, each NRB contains two guard intervals located on either side of the frequency domain bandwidth of each NRB.

The base station sends the frequency domain resource scheduling information to the user equipment, where the frequency domain resource scheduling information includes the resource number of the PRB closest to the resource block to be allocated and the resource number of the NRB included in the resource block to be allocated, so that the user equipment The frequency domain resource scheduling information determines the frequency domain resource information of the PRB closest to the resource block to be allocated and the frequency domain resource information of the NRB included in the resource block to be allocated, and causes the user equipment to use the frequency of the PRB closest to the resource block to be allocated. The domain resource information and the frequency domain resource information of the NRB included in the resource block to be allocated, transmit or receive a baseband signal.
