1. A method comprising:
- determining a location of a first node with respect to a second node and a third node using overheard messages from the second node and the third node;
determining a transmission mode for the first node based on the location of the first node; and
initiating a transmission from the first node using the determined transmission mode.

Abstract
According to some embodiments, directional and omni-directional messages are exchanged between two nodes during a control message exchange procedure in a wireless network. In other embodiments, only directional messages may be exchanged during the control message exchange. These directional and omni-directional control messages are used to provide location information to neighboring nodes which may overhear the control messages. The neighboring nodes may then be permitted transmit and receive in certain modes, depending on their location relative to one another.

17. A method comprising:
-
transmitting a Request To Send (RTS) message to a node; receiving a Clear To Send (CTS) message from the node; receiving a Direction Test (DT) packet from the node if the CTS message was an omni-directional CTS message; and transmitting a DT packet to the node if the RTS message was an omni-directional RTS transmission. - View Dependent Claims (18, 19, 20)

21. An system comprising:
-
a device; an antenna having directional transmission capability coupled to the device to support communication over a wireless communication link; and an antenna having omni-directional transmission capability coupled to the device to support communication over the wireless communication link, wherein the device is to transmit a Request To Send (RTS) message via the wireless communication link, to receive a Clear To Send (CTS) message via the wireless communication link, to receive a Direction Test (DT) packet via the wireless communication link if the CTS message was an omni-directional CTS message; and
to transmit a DT packet using the directional antenna if the RTS message was transmitted via the omni-directional antenna. - View Dependent Claims (22, 23, 24)
