Problems solved by technology

Limited by the narrow spectrum resources, for example, in the spectrum of the power system, the bandwidth of a single carrier is only 25kHz. The current discrete narrowband communication system can only support low-rate services, so the communication applications that can be supported are limited

Abstract

A communication method and device are applied to discrete narrow-band communication information to realize the aggregation of discrete sub-bands and support high-speed data transmission. In this method, the network device sends the first indication information to the terminal, and the first indication information includes the frequency point of the starting sub-band in all the discrete sub-bands of the serving cell of the terminal, and bits representing whether each sub-band in the frequency band belongs to the serving cell Figure, and the frequency spacing of each sub-band in the frequency band. The terminal receives the first indication information sent by the network device, and determines frequency points of all discrete subbands of the cell. The network device sends second indication information to the terminal, where the second indication information is used to indicate subbands that the terminal can use in all discrete subbands of the cell. The terminal receives the second indication information sent by the network device, determines the subbands that the terminal can use in all the discrete subbands of the cell, and then performs data transmission on the subbands that can be used to realize the aggregation of discrete subbands to support high-speed data transmission.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In existing discrete narrowband communication systems, only single carrier data transmission is supported. Limited by the narrow spectrum resources, for example, in the spectrum of the power system, the bandwidth of a single carrier is only 25kHz. The current discrete narrowband communication system can only support low-rate services, so the communication applications it can support are limited. However, with the development of business requirements, such as power distribution automation business in the power industry, video surveillance and other high-speed business, a new communication technology is needed to support high-speed data transmission by using discrete narrow-band spectrum. Contents of the invention [0003] Embodiments of the present application provide a communication method and...
