Abstract

A communication system is provided that includes nodes and communication controllers each operating with multiple antennas. During communications, the communication controller assigns timeslots to individual nodes for transmitting requests to a controller. When an individual node has data to transmit, the node transmits a request signal to a communication controller over the assigned timeslot. After receipt of a grant, the node transmits the data message in packetized form to the controller. The request, grant and data message can be transmitted and received using multiple antennas on both the node and the controller.

Claims

1-14. -14. (canceled)

15. A method of communicating in a network comprising:

transmitting a reservation request from the first node to a communication controller in a slot of a frame when the first node has at least one packet data message prepared for transmission;

receiving a grant signal from the communication controller in response to the communication controller receiving the first request signal from the first node; and

transmitting the at least one packet data message from the first node to the communication controller in response to receiving the grant signal from the communication controller,

wherein the first node transmits and receives the at least one packet data message over multiple antennas comprising at least two antennas.

16. The method of claim 15, wherein the multiple antennas comprise at least one antenna for transmitting information and at least one antenna for receiving information.

17. The method of claim 15, wherein the multiple antennas comprise at least one antenna for transmitting information and at least two antennas for receiving information.

18. The method of claim 15, wherein said multiple antennas comprise at least two antennas for transmitting information and at least one antenna for receiving information.

19. The method of claim 15, wherein said multiple antennas comprise at least two antennas for transmitting information and at least two antennas for receiving information.

20. The method of claim 15, wherein the grant signal specifies at least one slot for the first node to transmit the at least one packet data message.

21. The method of claim 15, wherein the grant signal specifies at least one frequency for the first node to transmit the at least one packet data message.

22. The method of claim 15, wherein the at least one packet data message is transmitted by the first node over at least one slot and over at least one frequency specified by the grant signal.

23. The method of claim 15, wherein the slot where the first node can send a reservation request is separate from one or more slots wherein the at least one packet data message is transmitted.

24. The method of claim 15, wherein prior to the step of transmitting the reservation request, the method further comprises:

receiving a communication-enabling signal from the first communication controller provided to the first node, the communication-enabling signal including information relating to the slot of the frame wherein the first node can transmit the reservation request.

25. A first node in a network, the network including a plurality of communication controllers, and a plurality of nodes including the first node, the first node comprising:

at least one processor;

a memory; and

an interface for transmitting data between the first node and the communication controllers, wherein the interface comprises at least two antennas for communicating with at least one antenna of the communication controller, wherein the interface is configured to;

transmit a reservation request from the first node to a communication controller in a slot of a frame when the first node has at least one packet data message prepared for transmission;

receive a grant signal from the first communication controller in response to the first communication controller receiving the first request signal from the first node; and

transmit the at least one packet data message from the first node to the first communication controller in response to receiving the grant signal from the communication controller.

26. A method of communicating in a network comprising:

receiving a reservation request from the first node at a communication controller in a slot of a frame;

transmitting a grant signal from the communication controller in response to the communication controller receiving the first request signal from the first node; and

receiving at least one packet data message from the first node at the communication controller,

wherein the first controller transmits and receives the at least one packet data message over multiple antennas comprising at least two antennas.

27. The method of claim 26, wherein the multiple antennas comprise at least one antenna for transmitting information and at least one antenna for receiving information.

28. The method of claim 26, wherein the multiple antennas comprise at least one antenna for transmitting information and at least two antennas for receiving information.

29. The method of claim 26, wherein said multiple antennas comprise at least two antennas for transmitting information and at least one antenna for receiving information.

30. The method of claim 26, wherein said multiple antennas comprise at least two antennas for transmitting information and at least two antennas for receiving information.

31. The method of claim 26, wherein the grant signal specifies at least one slot and at least one frequency for the first node to transmit the at least one packet data message.

32. The method of claim 26, wherein the slot where the first node can send a reservation request is separate from one or more slots wherein the at least one packet data message is transmitted.

33. The method of claim 26, wherein prior to the step of transmitting the reservation request, the method further comprises:

receiving a communication-enabling signal from the first communication controller provided to the first node, the communication-enabling signal including information relating to the slot of the frame wherein the first node can transmit the reservation request.

34. A first controller in a network, the network including a plurality of communication controllers including a first communication controller, and a plurality of nodes, the first controller comprising:

at least one processor;

a memory; and

an interface for transmitting data between the communication controller and a first node in the plurality of nodes, wherein the interface comprises at least two antennas for communicating with at least one antenna of the first node, wherein the interface is configured to;

receive a reservation request from the first node at the first communication controller in a slot of a frame;

transmit a grant signal from the first communication controller in response to the first communication controller receiving the first request signal from the first node; and

receiving at least one packet data message from the first node at the first communication controller.
