Method and apparatus for discovering neighbor nodes in a wireless communication network
First Claim
1. A method for operating a second node to discover neighboring nodes in a wireless communication, the method comprising:
- receiving, from a first node, first discovery information including awareness information, hop information indicating a hop limit corresponding to a number of available relays, and indication information indicating whether to allow a relay;
displaying a first user interface (UI) for determining whether to register the first node according to the awareness information;
in response to detecting a first user input on the first UI, transmitting, to the first node, a response message for indicating that the second node registers the first node;
when the indication information indicates allowance of the relay and the hop limit is greater than or equal to 1, displaying a second UI for determining whether to transmit second discovery information to a third node;
in response to detecting a second user input on the second UI, generating the second discovery information based on the first discovery information; and
transmitting the generated second discovery information to the third node,wherein generating the second discovery information comprises;
generating application layer information including the awareness information, the indication information, and another hop information indicating a hop limit smaller by one than the hop limit included in the first discovery information on an application layer according to the second user input detected on the second UI; and
generating the second discovery information as a medium access control (MAC) layer packet by adding a MAC header and an internet protocol (IP) header to the application layer information, andwherein the generated second discovery information is transmitted to the third node on the MAC layer with a physical layer processing.

Abstract
A method for processing a first node to configure a neighbor network in a wireless communication system including the first node and one or more second nodes neighboring the first node. The method includes generating discovery information; and broadcasting the generated discovery information to one or more of the second nodes. The discovery information includes information of the first node, an indicator indicating whether to receive the discovery information and accept the relay of the received discovery information to other nodes, and a hop limit indicating the number of available relays of the discovery information. A value of the indicator is set through an input of a user.

6. An apparatus of a second node to discover neighboring nodes, the apparatus comprising:
-
at least one transceiver; and at least one processor operatively coupled to the at least one transceiver, and configured to; receive, from a first node, first discovery information including awareness information, a hop information indicating a hop limit corresponding to a number of available relays of the first discovery information, and indication information indicating whether to allow a relay, display a first user interface (UI) for determining whether to register the first node according to the awareness information, in response to detecting a first user input on the first UI, transmit, to the first node, a response message for indicating that the second node registers the first node, when the indication information indicates allowance of the relay, display a second UI for determining whether to transmit second discovery information to a third node, in response to detecting a second user input on the second UI, generate the second discovery information based on the first discovery information, and transmit the generated second discovery information to the third node, wherein the at least one processor is, in order to generate the second discovery information, configured to; generate application layer information including the awareness information, the indication information, and another hop information indicating a hop limit smaller by one than the hop limit included in the first discovery information on an application layer according to the second input detected on the second UI; and generate the second discovery information as a medium access control (MAC) layer packet by adding a MAC header and an internet protocol (IP) header to the application layer information, and wherein the generated second discovery information is transmitted to the third node on the MAC layer with a physical layer processing. - View Dependent Claims (7, 8, 9, 10)
