System and method for performing low-overhead, high spatial reuse medium access control in a wireless network
First Claim
1. A method for communicating in a wireless network, the method comprising:
- operating a node in the wireless network to provide a packet for transmission, such that a header of the packet is provided for transmission at a first processing gain and a payload of the packet is provided for transmission at a second processing gain lower than the first processing gain; and
further comprising;
operating the node to select the first and second processing gains based on another node in the network, such that the first processing gain is sufficient to enable said another node to receive and process information in the packet header, or the second processing gain is high enough so that a destination node to which information in the payload is addressed is able to receive and process the information in the payload in the event that the another node is unable to receive and process the information in the packet header.

Abstract
A system and method for avoiding collisions between packets transmitted in a wireless network (100). A first node (102, 106 or 107) in the wireless network (100) can transmit a packet to a second node (102, 106 or 107) in the wireless network (100), such that packet includes a header that is transmitted with a higher processing gain than the data, therefore, may be received and processed by a third node (102, 106 or 107. This allows the third node (102, 106 or 107) to detect the transmission of a packet by the first node (102, 106 or 107), which can cause the third node (102, 106 or 107) to avoid transmission of a packet during the transmission by the first node (102, 106 or 107) to avoid collision between the packets. The system and method further enables the nodes (102, 106 or 107) to determine whether they can transmit to another node (102, 106 or 107) based on estimates of interference conditions that can be experienced due to the presence of other nodes (102, 106 or 107).

9. A wireless communication network, comprising:
-
a first node, adapted to provide a packet for transmission, such that a header of the packet is provided for transmission at a first processing gain and a payload of the packet is provided for transmission at a second processing gain lower than the first processing gain; and
further comprising;at least one other node, adapted for communication in the network; and wherein the first node is further adapted to select the first and second processing gains based on said other node in the network, such that the first processing gain is sufficient to enable said other node to receive and process information in the packet header, or the second processing gain is high enough so that a destination node to which information in the payload is addressed is able to receive and process the information in the payload in the event that the another node is unable to receive and process the information in the packet header. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
