Abstract: Various systems and methods are provided for channel estimation. These systems and methods (a) determine a coherence bandwidth for the channel, (b) adapt the channel estimation based on the coherence bandwidth, and (c) perform channel estimation by transmitting a channel estimation symbol over a channel. In some embodiments, the channel estimation is adapted based on the coherence bandwidth. This may include selecting a number of channel estimation symbols to transmit in a packet. Additionally, the number of channel estimation symbols transmitted in a packet can be selected by increasing the number of channel estimation symbols when the coherence bandwidth of the channel is high or decreasing the number of channel estimation symbols when the coherence bandwidth of the channel is low.

Abstract: A method is disclosed in which a first data transmission is received at a first network node from a second network node in a coordinated network. The first data transmission is received in a first bandwidth of a coordinated network and includes a first plurality of subcarriers. A second data transmission is received at the first network node from a third network node. The second data transmission is received in a second bandwidth of the coordinated network and includes a second plurality of subcarriers. A first transmission schedule is transmitted from the first network node to the second and third network nodes. The first transmission schedule includes modified first and second bandwidths in which the modified first bandwidth includes a subcarrier reallocated from the second bandwidth. The first network node receives data in accordance with the first transmission schedule.

Abstract: A method includes receiving a request for bandwidth from a first network node of a coordinated network and broadcasting a first transmission schedule to a plurality of network nodes including the first network node. The first transmission schedule allocates bandwidth for the first network node to transmit data to a second network node. An acknowledgement (ACK) message is received from the second network node identifying that the second network node successfully received the data from the first network node.
