Description

Transmission control method

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for uplink data transmission, a wireless access network device, and a terminal.

In millimeter-wave systems, an important limitation is that the communication link between the millimeter-wave transmitting node or the base station and the terminal is easily blocked by moving objects, and the solution to this problem can be applied to ultra-dense network deployment and beamforming. (beamforming) operation to ensure the communication quality of millimeter waves.

In the 5G field, we will study beam grouping, reporting, beam group based indication beam measurements, beam based transmission, and conversion. 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 are divided into beam pairs; or For a terminal, split multiple transmit beams and/or receive beams into beam sets; or divide multiple transmit and/or receive beam pairs into sets of beam pairs.

For example, when the identifier of the second beam group is a dominant indication, the identifier of the first beam group is “5”, and the identifier of the second beam group may be “6” or “1”.

In this case, the identifier of the first beam group corresponds to the reference measurement result corresponding to the first beam group, that is, the identifier of the first beam group is “5”, and the corresponding identifier of the corresponding reference measurement result is also “5”.
