Method and apparatus for adjusting transmit power

摘要

The present invention relates to the field of information communication and control, and discloses a method and an apparatus for adjusting transmit power and used to resolve a problem of interference between paths in a multipath system. The method provided by the present invention specifically includes: determining a path with worst signal quality according to signal quality information of each path; then, increasing transmit power of the path, or, decreasing transmit power of at least one path that produces strongest interference to the path with the worst signal quality; and finally, using a manner of cyclically adjusting signal transmit power to enable interference between the paths to meet a requirement of not affecting communications quality, thereby resolving a problem of interference between paths in a multipath system. Embodiments of the present invention are mainly used in a data transmission process in a multipath system.

主权项

1. A method for adjusting transmit power for use in a multipath system, the method comprising:
acquiring signal quality information of each path, wherein the signal quality information is used to indicate a difference between actual received signal quality and ideal received signal quality of a single path; determining a path with worst signal quality according to the signal quality information of each path, wherein in all the paths, the path with the worst signal quality is a path with a maximum difference between actual received signal quality and ideal received signal quality when a maximum difference between signal quality information of every two paths does not meet a preset condition; increasing transmit power of the path with the worst signal quality, or, decreasing transmit power of at least one path that produces strongest interference to the path with the worst signal quality; and sequentially repeating the foregoing steps until the maximum difference between the signal quality information of the every two paths in all the paths meets the preset condition.
