Method, system and apparatus for indicating resource position and blindly decoding channel

A method for blindly decoding a physical downlink control channel, comprising:

• receiving, by a user equipment, signalling sent from a base station, and determining a resource position of a Common Search Space, CSS, of a Physical Downlink Control Channel, PDCCH, and a resource position of a User Equipment-Specific Search Space, UESS, of the PDCCH according to the signalling, wherein the resource positions of the CSS and the UESS of the PDCCH are located in a control region and/or a data region of a downlink subframe;
• and
• performing, by the user equipment, CSS blind decoding of the PDCCH at the resource position of the CSS and performing UESS blind decoding of the PDCCH at the resource position of the UESS.

An apparatus for blindly decoding a physical downlink control channel, comprising:

• a resource position information receiving unit configured to receive signalling sent from a base station and to determine a resource position of a Common Search Space, CSS, of a Physical Downlink Control Channel, PDCCH, and a resource position of a User Equipment-Specific Search Space, UESS, of the PDCCH according to the signalling, wherein the resource positions of the CSS and the UESS of the PDCCH are located in a control region and/or a data region of a downlink subframe;
• and
• a channel blind decoding unit configured to perform CSS blind decoding of the PDCCH at the resource position of the CSS and perform UESS blind decoding of the PDCCH at the resource position of the UESS.
