Abstract
A hop-by-hop and multi-hop approach for fragmentation and packing are provided for a wireless multi-hop relay network. The fragmentation and packing operate at ingress, intermediate, and egress stations of a tunnel connecting a base station (BS) with an access relay station (RS). A format of the associated relay fragmentation and packing subheader are specified. In addition, a tunnel data includes numbered blocks to ensure correct packet sequencing for proper packet construction and reassembly for fragmentation and packing in the multi-hop relay network.
Claims19
A method for communicating packets in a wireless multi-hop relay network, in which the relay network includes a set of mobile stations, a set of relay stations, and a base station, wherein a particular relay station is an access relay station if the particular relay station is directly connected to a particular mobile station, comprising:
- establishing a tunnel between the access station and a base station, wherein the access station is an ingress station for the tunnel and the ingress station communicates with the set of mobile station and is at a first end of the tunnel, and an egress station communicates with the base station and is a last station at a second end of the tunnel;
- constructing a tunnel data unit from one or more media access control protocol data units (MPDUs) at the ingress station;
- transmitting the tunnel data unit from the ingress station to the egress station;
- and
- reconstructing the one or more MPDUs at the egress station.
The method of claim 14-bit block sequence number.
18 The method of claim 1, further comprising:
- inserting a packing subheader in front of a fragment of the tunnel data unit when constructing the one or more MPDUs with packing.
19 The method of claim 1, further comprising:
- inserting packing subheader in front of a tunnel data unit when creating the relay MAC PDU with packing.
