Apparatus and method for providing a relayed wireless communication path between cells

摘要

A first apparatus at a first base station changes directivity of a first antenna connected in a direction of a cell of a second base station adjacent to the first base station, where directivity of some antennas of a second apparatus at the second base station is changed to a cell of the first base station and some radio resources are assigned to wireless communication with the first apparatus. The first apparatus receives a signal of a first frequency from the second apparatus via the first antenna, converts the received signal into a signal of a second frequency, demodulates the signal of the second frequency, corrects a delay of the demodulated signal caused by propagation of a radio wave and frequency conversion, and modulates the corrected signal to a signal of a third frequency which is transmitted to a cell of the first base station via a second antenna.

主权项

1. A base station comprising:
a separation unit configured to separate a signal to be transmitted by a first antenna or a second antenna, from the signal received by the first antenna or the second antenna; a conversion unit configured to convert a frequency of a signal output from the separation unit; a demodulation unit configured to demodulate the signal output from the conversion unit; a correction unit configured to correct a delay of the signal output from the demodulation unit; and a modulation unit configured to modulate the signal output from the correction unit, wherein the base station causes:
the first antenna to change directivity thereof toward a cell of an adjacent base station and to receive a first signal of a first frequency from the adjacent base station;the conversion unit to convert the first signal of the first frequency into a second signal of a second frequency;the demodulation unit to demodulate the second signal of the second frequency;the correction unit to correct a delay in the second signal output from the demodulation unit, the delay including a first delay caused by a propagation of a radio wave from the adjacent base station to the base station and a second delay caused by a frequency conversion performed by the conversion unit;the modulation unit to modulate the second signal output from the correction unit to a third signal of a third frequency, and to output the third signal of the third frequency to the separation unit; andthe second antenna to transmit the third signal of the third frequency to the cell of the base station.
