CONTROL CHANNEL TRANSMISSION METHOD, NETWORK DEVICE AND TERMINAL DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/112935

Kind Code:

A1

Abstract:

Disclosed are a control channel transmission method, a network device and a terminal device. The method comprises: a first network device receiving first information, which is sent by a second network device, comprising information for indicating a first time-frequency resource; the first network device determining a second time-frequency resource in a control region of a second beam, the second time-frequency resource comprising at least part of the first time-frequency resource; the first network device receiving second information sent by the second network device, the second information comprising a control channel; and the first network device sending, on the second time-frequency resource, the control channel to a terminal device via the second beam, wherein a first beam is a service beam of a first terminal device, and the second beam is a non-service beam potentially interfering with the service beam of the first terminal device. In the control channel transmission method of the present application, a non-service beam is used to assist a service beam to transmit a control channel, so that the interference of the non-service beam can be avoided, joint transmission can be achieved, and the reception performance of the control channel can be enhanced.
