Embodiment 1

[0061] The bandwidth supported by the terminal is 5MHz. It is pre-agreed that when the working bandwidth of the terminal is smaller than the system bandwidth, the central frequency of the working bandwidth of the terminal is the same as the central frequency of the system bandwidth. The system bandwidth is 10MHz.

[0062] In step 301, the terminal reads that the system bandwidth in the system broadcast is 10MHz;

[0063] In step 302, the terminal compares the system bandwidth with the bandwidth supported by the terminal, and the system bandwidth is greater than the bandwidth supported by the terminal;

[0064] In step 303, the terminal determines that its working bandwidth is equal to the bandwidth supported by the terminal, that is, 5 MHz.

[0065] Further, in step 307, according to the pre-agreement, that is, when the working bandwidth of the terminal is smaller than the system bandwidth, the center frequency of the working bandwidth of the terminal is the same as the cent...

Embodiment 2

[0068] The bandwidth supported by the terminal is 5MHz. It is pre-agreed that when the system bandwidth is less than or equal to the bandwidth supported by the terminal, the working bandwidth of the terminal is the system bandwidth. The system bandwidth is 5MHz.

[0069] In step 301, the terminal reads that the downlink system bandwidth in the system broadcast is 5MHz;

[0070] In step 302, the terminal compares the system bandwidth with the bandwidth supported by the terminal, and the system bandwidth is equal to the bandwidth supported by the terminal;

[0071] In step 304, according to the pre-agreement, that is, when the system bandwidth is less than or equal to the bandwidth supported by the terminal, the working bandwidth of the terminal is the system bandwidth, and the terminal determines that its working bandwidth is equal to the system bandwidth, ie 5 MHz.

[0072] In step 308, the terminal works according to the existing data transmission mechanism within the bandw...

Embodiment 3

[0074] The bandwidth supported by the terminal is 5MHz. The system bandwidth is 5MHz. System broadcast notification When the system bandwidth is less than or equal to the bandwidth supported by the terminal, the working bandwidth of the terminal is 3MHz. System broadcast notification When the working bandwidth is smaller than the system bandwidth, the center frequency of the working bandwidth is shifted downward by 1MHz relative to the center frequency of the system bandwidth.

[0075] In step 301, the terminal reads that the downlink system bandwidth in the system broadcast is 5MHz;

[0076] In step 302, the terminal compares the system bandwidth with the bandwidth supported by the terminal, and the system bandwidth is equal to the bandwidth supported by the terminal;

[0077] In steps 304-305, according to the system broadcast notification, when the system bandwidth is less than or equal to the bandwidth supported by the terminal, the working bandwidth of the terminal is 3...

Abstract

Disclosed are a method and for determining a terminal working bandwidth and a terminal. The method comprises: a terminal obtaining a system bandwidth in system broadcast; the terminal comparing the obtained system bandwidth with a bandwidth supported by the terminal; the terminal determining a working bandwidth thereof according to a comparison result. By means of the present invention, the terminal determines the working bandwidth thereof according to the system bandwidth in the case that the working bandwidth of the terminal is different from the system bandwidth.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for determining the operating bandwidth of a terminal and a terminal. Background technique [0002] The Internet of Things technology is in the ascendant, and the third-generation mobile communication system and its long-term evolution system (Long Term Evolution, LTE) need to support the MTC (Machine Type Communications, Machine Type Communication) function. An MTC device (MTC terminal) may have some of the communication characteristics of various small bandwidth systems (machine to machine, Machine to Machine), such as low mobility, small amount of transmitted data, insensitivity to communication delay, requirements Features such as extremely low power consumption. [0003] As a new communication concept, Machine-to-machine (M2M) communication aims to organically combine various types of communication technologies, such as: machine-to-machine communication, machine c...
