Abstract

Embodiments of the present invention provide a control channel transmission method and device, the method comprising: the communication system configures at least two control channels for the user equipment, at least one of the control channels is a cell-specific control channel, and one of the control channels At least one is a user equipment-specific control channel; the communication system sends control information to the user equipment through the cell-specific control channel and / or the user equipment-specific control channel. In the embodiment of the present invention, the communication system configures at least two control channels for the UE, and the communication system can send control information to the UE through another control channel during the reconfiguration process of one control channel, thereby ensuring that the UE is in the cell. Communication is not interrupted when switching between them.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control channel transmission method and equipment. Background technique [0002] In the 3rd Generation Partnership Project (3GPP for short) Long Term Evolution (LTE for short) system, one user equipment (User Equipment, UE for short) can be served by multiple cells. Cell and the second serving cell as an example, 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 the UE is 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 (RRC) reconfiguration signaling to the UE to instruct the UE to reconfigure the ePDCCH , when the UE reconfigures the ePDCCH, it will feed bac...
