Method for selecting control channel, and apparatus

A user equipment (UE), applied to a communications system in which at least two control channels are configured, wherein the UE comprises:

• a processor, configured to:
• listen to a first control channel, and measure a value of a performance parameter of a signal received by using the first control channel, wherein the performance parameter comprises one or more of the following:
• a signal-to-noise ratio, a receive level, a signal to interference plus noise ratio, or signal strength, and the first control channel is one of the at least two control channels;
• and
• the prosessor is further configured to:
• when determining, according to the value of the performance parameter, that the first control channel meets a residence condition, determine the first control channel as a target control channel, wherein the target control channel is used to receive downlink control information sent by a base station.
