Phase adjusting method and apparatus
First Claim
1. A phase adjusting method comprising:
- a first step of commonly mapping a reference signal generated in a first device to respective down main signal frames of a first and a second system to be outputted to a second device;
a second step of mapping, at the second device, respective pointer values indicating timings of the reference signal in the respective down main signal frames to respective up main signal frames of the first and the second system to be outputted to the first device; and
a third step of extracting, at the first device, the respective pointer values from the respective up main signal frames and adjusting phases of the respective up main signal frames based on the respective pointer values.

Abstract
In a phase adjusting method and device in which a phase deviation between main signal frames themselves returned from a station end device through an antenna end device to the station end device without using a control signal for the phase adjustment, a reference signal generated in a first device is commonly mapped to respective down main signal frames of a first and a second system to be outputted to a second device, the second device maps, pointer values indicating timings of the reference signal in the respective down main signal frames to respective up main signal frames of the first and the second system to be outputted to the first device, and the first device extracts respective pointer values from the respective main signal frames and adjust frames of the respective up main signal frames based on the respective pointer values.
