Methods for detecting and sending downlink control information and devices

A method for sending downlink control information, the method comprising:

• acquiring a pilot port determining parameter that corresponds to downlink control information;
• determining, according to the pilot port determining parameter, a first-type pilot port that corresponds to the downlink control information;
• and
• sending the downlink control information according to the first-type pilot port, wherein the pilot port determining parameter is determined according to at least one of the following:
• a format of the downlink control information, a carrier index, configuration information of a second-type pilot, resource configuration information of the downlink control information, and a layer index of the downlink control information.

User equipment, comprising:

• a processor and a memory, wherein the memory is configured to store execution instructions;
• and
• when the user equipment runs, the processor communicates with the memory, and the processor executes the execution instructions so that the user equipment is configured to:
• acquire a pilot port determining parameter that corresponds to downlink control information needing to be detected,
• determine, according to the pilot port determining parameter, a first-type pilot port that corresponds to the downlink control information, and
• detect the downlink control information according to the first-type pilot port, wherein the pilot port determining parameter is determined according to at least one of the following:
• a format of the downlink control information, a carrier index, configuration information of a second-type pilot, resource configuration information of the downlink control information, and a layer index of the downlink control information.

A base station, comprising:

• a processor and a memory, wherein the memory is configured to store execution instructions;
• and
• when the user equipment runs, the processor communicates with the memory, and the processor executes the execution instruction so that the user equipment is configured to:
• acquire a pilot port determining parameter that corresponds to downlink control information,
• determine, according to the pilot port determining parameter, a first-type pilot port that corresponds to the downlink control information, and
• send the downlink control information according to the first-type pilot port, wherein the pilot port determining parameter is determined according to at least one of the following:
• a format of the downlink control information, a carrier index, configuration information of a second-type pilot, resource configuration information of the downlink control information, and a layer index of the downlink control information.
