Abstract

The invention discloses a method, device and system for sending cell information, which overcomes the defect that the CPC design scheme in the prior art cannot be widely compatible with existing terminals. The method includes: Time and frequency resources are assigned on the first frequency band used by the downlink channel of the access point, or on the third frequency band in the downlink channel networking frequency band of the system to which the first wireless access point belongs, as the second frequency resource at the second site. The cell information sending window of the second wireless access point configured with downlink traffic channel and / or control channel on the second frequency band; the second cell uses the cell information sending window based on the time of the first wireless frame sent by the first wireless access point The included time-frequency resources send cell information of the second wireless access point on the second frequency band. The embodiment of the present invention overcomes the disadvantage that existing CPC technical solutions cannot be widely compatible with existing terminals, and is easy to realize full compatibility with existing terminals.

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 concept of Common Pilot Channel (CPC: Common Pilot Channel) or Cognitive Pilot Channel (CPC: CognitivePilot Channel) has been proposed. , see "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 sent on the working frequency band of one of the systems using the wirel...
