Problems solved by technology

However, when using multiple (cluster) discrete frequency bands for communication, if the broadcast channel is only designed in one cluster of frequency bands, then when this continuous channel is strongly interfered, the UE cannot search for the synchronization channel, nor can it complete cell parking. stay, and cannot receive broadcast channel information

Embodiment Construction

[0026] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The present invention provides a signal transmission method of a synchronization channel and a broadcast channel under a discrete spectrum system, and further provides a method for UE access according to the transmitted synchronization and broadcast channel signals. Next, the specific implementation of the present invention will be described in detail.

[0028] The signal transmission method of the synchronization channel and the broadcast channel of the present invention includes: in the cell of the discrete spectrum system, pre-specify the position used for transmitting the synchronization channel and the broadcast channel in each cluster, and at the pre-designated position in each cluster The signals of the synchronization channel and the broadcast channel...

Abstract

The invention provides a signal transmission method and a UE (User Equipment) access method of a synchronizing channel and a broadcast channel in a discrete spectrum system, which comprises the following steps that signals of the synchronizing channel and the broadcast channel are transmitted in a preset position in each cluster frequency band of the discrete spectrum system, the signals of the synchronizing channel and the broadcast channel on each cluster of the discrete spectrum system are received by the UE, and one cluster with a best signal is selected to be resided and initiate access according to the received signals. According to the signal transmission method and the UE access method, the detection probability of the synchronizing channel and the broadcast channel can be increased, and the UE access probability is effectively increased.

Description

technical field [0001] The present invention relates to a synchronization channel and a broadcast channel technology in a communication system, in particular to a signal transmission method and a UE access method of a synchronization channel and a broadcast channel under a discrete spectrum 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 230MH...
