Abstract

The invention discloses a method for transmitting control channel indication information, a base station and user equipment. The method comprises the following steps of: determining a format of an extended physical downlink control channel (E-PDCCH), wherein the format of the E-PDCCH comprises a resource allocation and / or transmission mode of the E-PDCCH; and transmitting E-PDCCH indication information to user equipment on resources mapped by at least one control channel element (CCE) of a physical downlink control channel (PDCCH), wherein the E-PDCCH indication information is used for indicating the format of the E-PDCCH. The base station comprises a determination module and a transmission module. The user equipment comprises a receiving module and a determination module. The method, the base station and the user equipment of the embodiment of the invention can be used to dynamically transmit the E-PDCCH indication information, thereby enhancing the resource utilization efficiency of a system and a transmission performance of the E-PDCCH.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting control channel indication information in the communication field, a base station and user equipment. Background technique [0002] In the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, referred to as "3GPP") long-term evolution (Long Term Evolution, referred to as "LTE") communication system, the time-frequency resources in each downlink subframe are divided into Two areas: one area is used for the transmission of the Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as "PDCCH"), called the PDCCH area, and the other area is used for the Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as "PDCCH") PDSCH") transmission, called the PDSCH region. [0003] PDCCH and PDSCH are multiplexed in a downlink subframe in a time division multiplexing manner, and in the downl...
