Abstract

The embodiment of the invention provides a control channel transmission method and an apparatus. The method includes the following steps that: a communication system configures at least two control channels for user equipment, wherein at least one of the control channels is a community specific control channel, and at least one of the control channels is a user equipment specific control channel; and the communication system transmits control information for the user equipment through the community specific control channel and / or user equipment specific control channel. According to the embodiment of the invention, the communication system configures the at least two control channels for the user equipment, and the communication system can transmit the control information for the user equipment (UE) through one kind of control channel in the reconfiguration process of the other kind of control channel, and therefore, it can be ensured that communication is not interrupted when the user equipment (UE) is switched between communities.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a control channel transmission method and equipment. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system, a user equipment (User Equipment, UE) can be served by multiple cells, with the first serving For example, the cell and the second serving cell, the enhanced physical downlink control channel (Enhanced Physical Downlink Control Channel, ePDCCH for short) configured when the UE is served by the first serving cell, and the ePDCCH configured when served by the second serving cell different. [0003] In the prior art, when the UE switches from the first serving cell to the second serving cell, the first serving cell will send radio resource control (Radio Resource Control, RRC) reconfiguration signaling to the UE to instruct the UE to reconfigure the ePDCCH After the UE reconfigures the ePDCCH, it will feed...
