Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The invention provides a communication method for a broadband terminal under a discrete frequency spectrum system. Next, the specific implementation of the present invention will be described in detail.

[0021] The method of the present invention can support the discrete spectrum communication system of multiple technologies: as Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) communication system, Frequency Division Multiple Access (FDMA, Frequency Division Multiple Access) communication system, code CDMA, Code Division Multiple Access) communication system, or Time Division Multiple Access (TDMA, Time Division Multiple Access) communication system. The following embodiments are described by taking an OFDM communication system as an example.

[0022] In the present invention, the...

Abstract

The invention discloses a service communication method of a broadband terminal in a discrete spectrum communication system, comprising the following steps: when the broadband terminal needs to perform service data transmission, the base station distributes broadband frequency ranges to the broadband terminal and transmits identification information of the distributed broadband frequency ranges to the broadband terminal through a downlink control information command; the broadband terminal migrates from own resident frequency range to the broadband frequency range identified by the broadband frequency range identification information and transmits service data and related control signaling in the broadband frequency range. The service communication method enables the discrete spectrum communication system to simultaneously support narrow-band terminals and broadband terminals and meet own service demands.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a communication method for broadband terminals in a discrete frequency spectrum communication 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] The 230MHz discrete spectrum communication system based on Time Division Long Term Evolution (TD-LTE, Time Di...
