Title:
TRANSMISSION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/052518
Kind Code:
A1
Abstract:
The embodiments of the present invention relate to a data transmission method. The method specifically comprises: a terminal sending, according to a first format of uplink control information (UCI), the UCI to a radio access network device, wherein the UCI sent in the first format comprises: at least one piece of measurement result information about a beam group and information about the beam group; the beam group comprises: a first beam group and a second beam group; the measurement information about the beam group comprises: a measurement result of the first beam group and an offset of a measurement result of the second beam group relative to the measurement result of the first beam group; the measurement result of the first beam group is a reference measurement result; the information about the beam group is used for indicating a beam group corresponding to at least one of the measurement result of the first beam group and the measurement result of the second beam group; and the beam group is one or more beam groups. In this solution, grouping beams helps to reduce the cost of beam management. In addition, the problem of uplink control information reporting being based on the grouped beam group in a millimeter wave system is solved, the measurement of the beam group after grouping and the reporting thereof through the uplink control information are implemented, the resources are rationally used, and the indirect cost of reporting is reduced.
