Abstract
The present disclosure discloses a beam selection method, a terminal device, and a computer storage medium, where the method includes: selecting a first transmission beam for transmitting data between a first terminal device and a second terminal device based on a geographical position of the first terminal device and a geographical position of the second terminal device; and transmitting data to the second terminal device based on the first transmission beam.
Claims7
A beam selection method, which is applied to a first terminal device, comprising:
- selecting a first transmission beam for transmitting data between the first terminal device and the second terminal device based on a geographical position of the first terminal device and a geographical position of the second terminal device;
- and
- transmitting data to the second terminal device based on the first transmission beam;
- wherein the selecting a first transmission beam for transmitting data between the first terminal device and the second terminal device based on a geographical position of the first terminal device and a geographical position of the second terminal device comprises:
- determining a relative position relationship between the first terminal device and the second terminal device based on the geographical position of the first terminal device and the geographical position of the second terminal device;
- and
- selecting the first transmission beam among N transmission beams between the first terminal device and the second terminal device based on the relative position relationship,
- wherein N is an integer greater than or equal to one;
- wherein the relative position relationship between the first terminal device and the second terminal device is a reference connection line between the first terminal device and the second terminal device;
- wherein the selecting the first transmission beam among the N transmission beams between the first terminal device and the second terminal device based on the relative position relationship comprises:
- selecting, among the N transmission beams, a transmission beam having a minimum angle from the reference connection line as the first transmission beam based on the reference connection line;
- or
- selecting, among the N transmission beams, M transmission beams whose angles from the reference connection line are smaller than a preset angular threshold based on the reference connection line;
- and selecting, among the M transmission beams, a transmission beam with optimal quality as the first transmission beam, wherein M is an integer lower than or equal to N;
- or
- selecting, among the N transmission beams, M transmission beams whose angles from the reference connection line are smaller than a preset angular threshold based on the reference connection line;
- and selecting, among the M transmission beams, a transmission beam as the first transmission beam by polling in sequence at preset time intervals.
