Embodiment Construction
[0029] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.
[0030] Since the frequency band resources of an LTE-A system are aggregated from frequency band resources of multiple LTE systems and some frequency band resources invisible to the LTE system, the embodiment of the present invention sets several main carrier frequency points on the frequency band of the LTE-A system , and the remaining carriers are secondary carriers. The synchronization signal and broadcast information of the LTE-A system are sent on the frequency point of the main carrier. The broadcast information of the LTE-A system includes the system information of the initial random access of each carrier in the system. Users of the LTE-A system can recognize these signals. LTE system users are invisible....

The invention discloses a signal transmission method and signal transmission equipment. The method comprises the following steps of: setting one or more main carrier frequency points in whole frequency band and configuring a synchronization channel and a broadcast channel of an LTE-A system on the main carrier frequency point; and transmitting synchronization signals and broadcast information of the LTE-A system on the synchronization channel and the broadcast channel of the LTE-A system respectively. The invention also provides a system random access method and user equipment. The signal transmission method, the signal transmission equipment, the system random access method and the user equipment can realize the configuration of the synchronization channel and the broadcast channel of the LTE-A system so that the user equipment of the LTE-A system can highly, efficiently and quickly access the system.
Description
technical field [0001] The present invention relates to communication technology, in particular to a signal sending method and equipment, and a system random access method and user equipment. Background technique [0002] Broadband wireless communication will become the main development direction of mobile communication in the future. Through broadband wireless communication, users can enjoy high-speed data download, online shopping, mobile video chat, mobile TV and many other wireless mobile services, which greatly meet the needs of users for wireless mobile Communication needs. In order to improve user experience quality, a wireless communication system needs to provide fast, accurate, and high-quality access services for user terminals. Users can get efficient user experience in different communication environments. [0003] In the existing LTE wireless communication standard, the maximum system bandwidth reaches 20MHz. In order to avoid the difficulty of system design,...
