Method and user equipment for determining control channel resource
In a process by user equipment (UE) to determine a control channel resource, the UE detects a downlink control from a base station. The downlink control channel carries scheduling information of a downlink data channel and comprises multiple control channel logical elements that correspond to the UE and are mapped to one demodulation reference signal (DMRS) antenna port. The UE acquires antenna port information of the DMRS antenna port, an offset, and sequence number information of the control channel logical elements corresponding to the UE, and determines, according to the acquired information, a first control channel resource for sending acknowledgment (ACK)/non-acknowledgment (NACK) information with respect to the downlink data channel corresponding to the downlink control channel.
