Method for sending an acknowledgement to an ingress mesh point in a mesh network and a medium access control frame format
First Claim
1. In a mesh wireless communication system comprising a plurality of mesh points that are wirelessly linked together such that a data packet sent by a station (STA) is received by an ingress mesh point (IMP) and forwarded to an egress mesh point (EMP) in order to provide a service by the mesh wireless communication system, a method for sending an acknowledgement (ACK) for the data packet to the IMP, comprising:
- generating a medium access control (MAC) frame for transmission of a data packet, the MAC frame including a field comprising an IMP address and an EMP address;
forwarding the MAC frame to the EMP via zero or more intermediate mesh point; and
sending an ACK for successful reception of the data packet to the IMP,wherein a frame control field of the MAC frame indicates that the MAC frame contains the IMP address and the EMP address.

Abstract
The present invention relates to a method for confirming the delivery of a data packet in a mesh network by sending an acknowledgement (ACK) to an ingress mesh point (IMP). A mesh network comprises a plurality of mesh points that are wirelessly linked together. A data packet sent by a station (STA) is received by an IMP. A MAC frame is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (EMP) in order to provide a service by the mesh network. The MAC frame includes a field comprising an IMP address and an EMP address. When the EMP, (or optionally an intermediate mesh point), receives a data packet successfully, the EMP or the intermediate mesh point sends an ACK to the IMP or preceding mesh point.

4. A method for routing a data packet in a mesh network, the method comprising:
-
receiving a data packet of a data communication that is sent towards a destination address from a source address, the data packet including control information that contemporaneously indicates a first address, as the source address, a second address, as the destination address, a third address for an ingress mesh point (IMP) through which data packets enter the mesh network and a fourth address for an egress mesh point (EMP) through which data packets exit the mesh network; and processing the control information to determine whether the data packet includes the IMP address and the EMP address. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A station (STA), comprising:
a receiver and a processor configured to; receive a data packet of a data communication that is sent towards a destination address from a source address, the data packet including control information that contemporaneously indicates a first address, as the source address, a second address, as the destination address, a third address for an ingress mesh point (IMP) through which data packets enter the mesh network and a fourth address for an egress mesh point (EMP) through which data packets exit the mesh network; and process the control information to determine whether the data packet includes the IMP address and the EMP address. - View Dependent Claims (12, 13, 15, 16)
