Title:
INFORMATION TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/171786
Kind Code:
A1
Abstract:
The present application provides an information transmission method and device. The method comprises: an access network device receives antenna port grouping information from a terminal device; the antenna port grouping information comprises information of at least one antenna port group of the terminal device and information of at least one antenna port comprised in each antenna port group, or information of at least one antenna port group of the terminal device and information of antenna ports of the terminal device; and the access network device sends, according to the antenna port grouping information, indication information to the terminal device, the indication information being used for indicating an antenna port group set used by the terminal device in performing uplink information transmission at a first moment, the antenna port group set comprising at least one first antenna port group, and the first antenna port group being one of the antenna port groups indicated by the antenna port grouping information. The method of the present invention prevents the terminal device from continuously transmitting uplink information on a shielded antenna port; therefore, the uplink information transmission efficiency of the terminal device is improved and the power consumption of the terminal device is also reduced.
