Method, device and system for transmitting enhanced downlink control channel

A device for receiving a downlink control channel, comprising:

• a processor;
• and
• a non-transitory memory, wherein the memory stores an execution instruction;
• and when the processor executes the execution instruction to enable the device to perform the following steps:
• receiving, using a DM RS port, a signal on at least one resource block pair, each of the at least one resource block pair comprises downlink control channel resources and demodulation reference DM RS resources, the downlink control channel resources comprise multiple control channel elements, and an allocation pattern of the control channel elements in the at least one resource block pair is bound to the DM RS port;
• performing channel estimation using all DM RSs received on the at least one resource block pair;
• and
• demodulating the signal received on the downlink control channel resources in the at least one resource block pair using a result of the channel estimation, to obtain a downlink control channel.

A non-transitory computer-readable medium storing processor-executable instructions, the processor-executable instructions, when executed by a processor, facilitating performance of a data transmission method, the data transmission method comprising:

• receiving, using a DM RS port, a signal on at least one resource block pair, each of the at least one resource block pair comprises downlink control channel resources and demodulation reference DM RS resources, the downlink control channel resources comprise multiple control channel elements, and an allocation pattern of the control channel elements in the at least one resource block pair is bound to the DM RS port;
• performing channel estimation using all DM RSs received on the at least one resource block pair;
• and
• demodulating the signal received on the downlink control channel resources in the at least one resource block pair using a result of the channel estimation, to obtain a downlink control channel.
