Method for sending control information, method for receiving control information, network device, and terminal device

A computer-readable storage medium comprising instructions which, when executed by a computer system, cause the computer system to perform operations comprising:

• determining at least one control channel element (CCE) corresponding to a control channel, wherein each CCE comprises a plurality of resource element sets, each resource element set of the plurality of the resource element sets comprises a first resource element for carrying downlink control information and a second resource element for carrying a DMRS, and the downlink control information carried by the resource element set is demodulated based on the DMRS;
• and
• receiving the downlink control information and the DMRS on the control channel;
• wherein:
• the control channel occupies one or more symbols, and
• in a first case where the control channel occupies only one symbol, the each resource element set occupies the same only one symbol, and frequency domain resources occupied by the each resource element set are consecutive in the only one symbol, or
• in a second case where the control channel occupies more than one symbol, the each resource element set occupies the same more than one symbol, frequency domain resources occupied by the each resource element set are the same in all of the more than one symbol, and the frequency domain resources occupied by the each resource element set are consecutive in each of the more than one symbol.

An apparatus, comprising:

• one or more processors;
• and
• one or more memories, wherein the one or more memories store a computer program for execution by the one or more processors to perform operations comprising:
• determining at least one control channel element (CCE) corresponding to a control channel, wherein each CCE comprises a plurality of resource element sets, each resource element set of the plurality of resource element sets comprises a first resource element for carrying downlink control information and a second resource element for carrying a DMRS, and the DMRS is used to demodulate the downlink control information carried by the control channel;
• and
• sending the downlink control information and the DMRS by using the control channel, wherein:
• the control channel occupies one or more symbols, and
• in a first case where the control channel occupies only one symbol, the each resource element set occupies the same only one symbol, and frequency domain resources occupied by the each resource element set are consecutive in the only one symbol, or
• in a second case where the control channel occupies more than one symbol, the each resource element set occupies the same more than one symbol, frequency domain resources occupied by the each resource element set are the same in all of the more than one symbol, and the frequency domain resources occupied by the each resource element set are consecutive in each of the more than one symbol.
