Embodiment Construction

[0023] The basic idea of ​​the present invention is: the user data transmission is only scheduled in a single frequency point, and the RNTI is unique in the frequency point; the combination of the frequency point identifier and the RNTI is used to distinguish users in the cell. Since the number of RNTIs in the same frequency point is much smaller than the number of RNTIs in a cell, the length of the RNTIs can be greatly shortened. Thereby reducing the complexity of scheduling and improving the simplicity of implementation.

[0024] For example, in a narrowband system with discrete spectrum, there are P (P≥1) discrete clusters in a cell, and each cluster contains Q (Q≥1) frequency points, then there are N (N= P*Q) frequency points.

[0025] A cell containing three discrete cluster frequency bands is taken as an example for illustration. figure 1 is the spectrum distribution diagram of the cell containing three clusters. Three discrete frequency bands are respectively distrib...

Abstract

The invention provides a method for distinguishing users in a narrow-band system. The method for distinguishing the users in the narrow-band system comprises the following steps of determining a frequency point used for dispatching a user before user data are transmitted, distributing an only radio network temporary identity (RNTI) to the user in the frequency point, and using combination of frequency point identifications and RNTIs to distinguish users. The method for distinguishing the users in the narrow-band system can greatly improve efficiency and reliability of data transmission.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for distinguishing users in a narrowband system. Background technique [0002] At present, the 230MHz frequency band is mainly used in data transmission stations to undertake remote data collection work. Because the provided rate is very low, it can only be used for some simple communication applications, and cannot meet the growing business needs of smart grids and sensor networks. According to the future planning of the State Grid, it is required to find a new broadband communication technology to meet the business needs of its distribution network automation, load management, electricity consumption information collection, smart grid user services, emergency repairs, and video surveillance in special areas. [0003] In order to provide high-speed data transmission services in the 230MHz frequency band, the applicant combined Orthogonal Frequenc...
