Method for transmitting cpc information, radio access method and system based on cpc information

Abstract

The disclosure provides a method for transmitting Cognitive Pilot Channel (CPC) information, a radio access method and system based on CPC information, wherein the method for transmitting CPC information includes: dividing a CPC into a primary CPC for transmitting primary CPC information and a secondary CPC for transmitting secondary CPC information; loading the primary CPC information periodically into fixed physical resources, and sending the primary CPC information to a user equipment; after a base station receives a preset triggering event, loading the secondary CPC information into variable physical resources, and sending the secondary CPC information to the user equipment. In the disclosure, the base station loads the primary CPC information into fixed physical resources of an RAT according to an RAT coverage condition, reducing the amount of information required to be delivered by fixed physical resources, decreasing occupation of fixed physical resources, speeding up radio access of the user equipment; and after receiving a triggering event, the base station loads the secondary CPC information into variable physical resources and sends the secondary CPC information to the user equipment, thus implementing optimization of a user network and radio resources.
