Abstract
Provided is a communication method and apparatus using a multi-radio. The communication method includes establishing a link via at least one node included in a group that uses a low data-rate radio (LDR); transmitting a data frame to the at least one node included in the group; and receiving, using a multi-radio based on an availability of the LDR, an acknowledgement (ACK) with respect to the transmitted data frame.
Claims24
A communication method executed by a head node of a first group, the method comprising:
- receiving, from each of a plurality of nodes forming the first group with the head node, a channel report frame including respective intensity information of a corresponding signal, the corresponding signal being received respectively by two or more nodes of the plurality of nodes in the first group directly from a neighbor head node of a different second group;
- selecting one of the plurality of nodes to be a communication partner based on two or more of the received respective intensity information of the corresponding signal received directly from the neighbor head node of the different second group;
- transmitting a data frame to the selected node;
- and
- transmitting, to the selected node, an acknowledgement (ACK) request frame which requests an ACK indicating whether the data frame is received.

A communication apparatus comprising:
- a receiver configured to receive, from each of a plurality of nodes forming a first group with the communication apparatus, a channel report frame including respective intensity information of a corresponding signal, the corresponding signal being received respectively by two or more nodes of the plurality of nodes in the first group directly from a neighbor head node of a different second group;
- and
- circuitry configured to:
- select one of the plurality of nodes to be a communication partner based on two or more of the received respective intensity information received of the corresponding signal directly from the neighbor head node of the different second group;
- control transmission of a data frame to the selected node;
- and
- control transmission of, to the selected node, an ACK request frame which requests an ACK indicating whether the data frame is received.
