Embodiment Construction

[0021] As mentioned above, the broadcast signals of the existing broadband system and narrowband system are usually independently designed, and the terminals suitable for the narrowband system cannot decode the broadcast signals of the broadband system, and the terminals suitable for the broadband system cannot decode the narrowband system. The broadcast signal of the system, and the broadcast signal of the broadband system and the broadcast signal of the narrowband system occupy different frequency bands of the system bandwidth.

[0022] For example, in an existing system, a broadcast signal of a broadband system, such as a broadcast signal of an LTE system, occupies 6 physical resource blocks (physical resource block, PRB) in the frequency domain, that is, a bandwidth of 1.08 MHz, where the primary synchronization signal ( Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) each occupy 1 symbol; in narrowband systems such as narrowband Internet of ...

Abstract

The invention provides a broadcast signal generation method and device. The method comprises the following steps: generating a first broadcast signal based on the length of the broadcast signal of a bandwidth system; circularly shifting the first broadcast signal to obtain a second broadcast signal, wherein an initial position of the second broadcast signal after frequency domain mapping is located at a frequency initial position, which is used for transmitting the broadcast signal, of a narrow-band system. By use of the method and device provided by the embodiment of the invention, the terminals of different bandwidth systems can decode the same broadcast signal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for generating a broadcast signal. Background technique [0002] The network side usually notifies the basic access information of the user terminal through a broadcast signal. In the existing system, services can be provided for terminals suitable for broadband systems and terminals suitable for narrowband systems. [0003] However, the broadcast signals of the existing broadband system and the narrowband system are usually independently designed, and the terminals suitable for the narrowband system cannot decode the broadcast signals of the wideband system, and the terminals suitable for the broadband system cannot decode the broadcast of the narrowband system. Signal. Contents of the invention [0004] The technical problem solved by the invention is that terminals suitable for different bandwidth systems cannot decode the same broadcast s...
