Abstract

The invention discloses a system, a device and a method for transmitting cell information to overcome the defect that a CPC (common pilot channel) design scheme in the prior art fails to realize wide compatibility to existing terminals. The method includes: appointing time and frequency resources on a first frequency band used by a first wireless access point downlink channel positioned at a first site or on a third frequency band in a downlink channel networking frequency band of a system to which a first wireless access point belongs, and using the appointed time and frequency resources as a cell information transmitting window of a second wireless access point which is positioned at a second site and allocates a downlink service channel and/or control channel on a second frequency band; and based on time of a first wireless frame sent by the first wireless access point, allowing a second cell to use time frequency resources contained in the cell information transmitting window to transmit cell information, on the second frequency band, of the second wireless access point. The system, the device and the method for transmitting cell information overcome the defect that the existing CPC technical scheme fails to be widely compatible to existing terminals, and complete compatibility to the existing terminals can be realized easily.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method, device and system for sending cell information, and a method for suppressing adjacent frequency interference. Background technique [0002] In order to realize the comprehensive utilization of resources between different systems and reduce the cost of cell search by terminals, the Common Pilot Channel (CPC: Common Pilot Channel) or Cognitive Pilot Channel (CPC: Cognitive Pilot Channel) has been proposed. For the concept, refer to the white paper of the FP7 project End-to-End Efficiency (E3) "Support for heterogeneous standards using CPC: Using CPC to support heterogeneous network standards" "Version release date: June 30, 2009 (Release Date: 30-06-2009). [0003] There are two types of existing CPC implementation schemes, one is in-band CPC, that is, the comprehensive information of multiple systems complying with different wireless technical specifications is...
