Radio channel assignment method and recording medium of program for controlling radio node
First Claim
1. A radio channel assignment method in a mesh-like network in which a plurality of radio nodes are arranged in a decentralized manner and radio channels adopting TDD architecture between a pair of opposite radio nodes are assigned in a decentralized manner to establish a radio link, comprising:
- a step of, for each radio link, locating respective ones of a pair of radio nodes terminating the radio link to either one of an upper side and a lower side exclusively; and
a step that one of a radio node located to an upper side from the radio link or a radio node located to a lower side therefrom assigns a frequency slot to each radio link, wherein the frequency slot is assigned such that coincidence in allocation attribute of TDD time slot is achieved in respective radio links.

Abstract
The present invention provides a radio channel assignment method where each node in a network assigns radio channels to respective radio links in a decentralized manner without inconsistency.
The radio channel assignment method includes a step of assigning one of a pair of nodes terminating each radio link and the other thereof to an upper side and a lower side (Step S1), and a step that each radio node located to the upper side from at least one of radio links terminating at an own node assigns a frequency slot different from that of an adjacent link to a radio link locating an own node to the upper side (Step S5).

10. A recording medium of a program for assigning radio channels arranged on a network in a decentralized manner and adopted TDD system between opposite radio nodes in decentralized manner to establish a radio link, comprising:
-
a step of, for each radio link terminating at an own node, locating the own node to an upper side or a lower side exclusively from an opposite node sharing the radio link;
a step of imparting a right for assigning a frequency slot to the radio link to one of the own node and the opposite node; and
a step of, when the right is imparted to the own node, assigning a frequency slot to the radio link, wherein the frequency slot controls a radio node to be assigned such that allocation attribute of TDD time slot in the radio link is coincident with that in another radio link. - View Dependent Claims (11, 12, 13)
