Embodiment Construction

[0166] In order to facilitate the understanding of the embodiments of the present invention, further explanations will be made below in conjunction with the drawings and specific embodiments, and the embodiments are not intended to limit the embodiments of the present invention.

[0167] Embodiments of the present invention provide a data transmission method, radio access network equipment, and terminal. By measuring the grouped beam groups and then sending UCI in the first format, it solves the problem that does not take into account the problems based on the millimeter wave system. The problem of reporting the uplink control information of the beam group. Therefore, this solution can effectively perform beam management, and report the uplink control information in the first format more accurately and reduce reporting indirect costs.

Abstract

Embodiments of the invention relate to a method for data transmission. The method comprises the following step that: the terminal transmitting the UCI to a radio access network device according to a first format which is comprised the uplink control information UCI. The UCI transmitted in the first format comprises measurement result information of beam groups and at least one of information of the beam groups. The beam groups comprise a first beam group and a second beam group. The measurement result information of the beam groups comprises a measurement result of the first beam group, and anoffset of the measurement result of the second beam group with respect to the measurement result of the first beam group. The measurement result of the first beam group is a reference measurement result. The information of the beam group is used to indicate 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. The beam group is one or more beam groups. According to the method for the data transmission, the cost of beam management for the beam groups is reduced. The problem that uplink control information based on grouped beam groups is reported in a millimeter wave system is solved, the measurement of the grouped beam groups is implemented and reported by the uplink control information, the resource is reasonably utilized, and the indirect cost of reporting is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for uplink data transmission, wireless access network equipment and a terminal. Background technique [0002] In mmWave systems, an important limitation is that the communication link between the mmWave transmitting node or base station and the terminal is easily obstructed by moving objects, and the solution to this problem can be applied ultra-dense network deployment and beamforming (beamforming) operation to ensure the communication quality of millimeter waves. [0003] In the field of 5G, we will study beam grouping, reporting, beam measurement based on beam group indication, beam based transmission and switching. Wherein, the beam group is defined as follows: for one transmission point or multiple transmission points, multiple transmission beams and / or reception beams are divided into beam sets; or, multiple transmission and / or reception beam pairs ...
