Signal transmission method, network device, and terminal device

A communication device, comprising:

• a processor, configured to:
• determine a first time-frequency resource, wherein the first time-frequency resource is a first candidate resource in a plurality of candidate resources;
• determine a second time-frequency resource and a third time-frequency resource according to a preset rule, wherein the third time-frequency resource comprises at least one resource element (RE) at a predefined location in the first time-frequency resource, the second time-frequency resource comprises a resource other than the third time-frequency resource in the first time-frequency resource, the second time-frequency resource is used to carry a beamformed control channel, and the third time-frequency resource is used to carry a reference signal of the beamformed control channel;
• and
• demodulate the beamformed control channel according to the reference signal.

A non-transitory computer-readable medium, wherein the non-transitory computer-readable medium stores instructions that, when executed by a processor, cause the processor to:

• determine a first time-frequency resource, wherein the first time-frequency resource is a first candidate resource in a plurality of candidate resources;
• determine a second time-frequency resource and a third time-frequency resource according to a preset rule, wherein the third time-frequency resource comprises at least one resource element (RE) at a predefined location in the first time-frequency resource, the second time-frequency resource comprises a resource other than the third time-frequency resource in the first time-frequency resource, the second time-frequency resource is used to carry a beamformed control channel, and the third time-frequency resource is used to carry a reference signal of the beamformed control channel;
• and
• demodulate the beamformed control channel according to the reference signal.
