Transmission control method

Abstract

The embodiment of the invention relates to a data transmission method. The method specifically comprises the following steps that a terminal sends UCI to wireless access network equipment according to a first format of the UCI, wherein the UCI sent in the first format comprises at least one of measurement result information of a beam group and information of the beam group, and the beam group comprises a first beam group and a second beam group, the measurement result information of the beam group comprises the offset of the measurement result of the first beam group and the offset of the 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, and the information of the beam group is used for indication; at least one of the measurement result of the first beam group and the measurement result of the second beam group corresponds to a beam group, and the beam group is one or more beam groups. In the scheme, the beam grouping is beneficial to reducing the cost of beam management. Meanwhile, the problem of reporting the uplink control information based on the grouped beam groups in the millimeter wave system is solved, the grouped beam groups are measured and reported through the uplink control information, resources are reasonably utilized, and indirect cost for reporting is reduced.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a method of uplink data transmission, a wireless access network device, and a terminal. Background technique [0002] In a millimeter wave system, an important limit is that the communication link between millimeter wave transmitting nodes or base stations and terminals is easily obstructed by moving objects, while the method of solving this problem can apply super-intensive network deployment and beamforming. (beamforming) operation to ensure the quality of the millimeter wave. [0003] In the 5G field, we will study the packets, reports, and based on the instructions of beam groups, based on beam-based transmission and conversion. The beam group is defined as follows: For a transfer point or multiple transfer points, multiple transmission beams and / or receiving beam are divided into beam collection; or divide multiple transmission and / or reception beams ...
