A method and apparatus for the receiver directed assignment of receive slots in a dynamic assignment communication system. The apparatus including a memory component storing communication assignment data for a plurality of time slots in a time multiplex structure and a processor component capable of identifying a set of available time slots from the plurality of time slots. The apparatus being capable of assigning itself a receive slot, which can be a broadcast receive slot, from the set of available time slots. The method involves establishing a network wherein network communication is accomplished via assignment of specific time slots of a time multiplex structure. The method further involves determining a set of available time slots suitable for reception, by a receiving node, of a communication from a neighboring node, the receiving node then assigning to itself a receive slot from the set of available time slots. The method and apparatus are also capable of handling transmissions from a plurality of neighboring devices during a broadcast receive slot. This can be accomplished by a scheduling technique, a random access technique or a code division multiple access technique.

1. A method of managing communication resources to permit receiver-directed receive slot allocation in a network having a plurality of nodes, each node communicating during specific time slots on a time multiplex basis, the method comprising:establishing a network comprising a plurality of nodes, wherein network communication is accomplished via assignment of specific time slots of a time multiplex structure, said plurality of nodes participating in a dynamic assignment protocol wherein a node of said plurality of nodes is capable of assigning itself a time slot from said time multiplex structure;determining a set of available time slots that are suitable for reception by said node of said plurality of nodes of a communication from a neighboring node;assigning to said node of said plurality of nodes a receive slot from said set of available time slots, said receive slot having been assigned by said node; andaccessing using a random access technique to coordinate communication;wherein said receive slot is a broadcast receive slot. 2. The method of claim 1, wherein said dynamic assignment protocol comprises a unifying slot assignment protocol. 3. The method of claim 1, wherein said time multiplex structure comprises a time division multiple access protocol. 4. The method of claim 1, wherein said time multiplex structure further comprises a plurality of frequency channels. 5. The method of claim 1, wherein said time multiplex structure further comprises a plurality of code division multiple access channels. 6. The method of claim 1, wherein said determining step comprises excluding from said set of available time slots those time slots in which a neighbor of said neighboring node is receiving. 7. The method of claim 1, further comprising the step of using said receive slot, by said node, to receive a communication from at least one neighboring node of said node of said plurality of nodes. 8. A method of managing communication resources to permit receiver-directed receive slot allocation in a network having a plurality of nodes each node communicating during specific time slots on a time multiplex basis, the method comprising:establishing a network comprising a plurality of nodes, wherein network communication is accomplished via assignment of specific time slots of a time multiplex structure, said plurality of nodes participating in a dynamic assignment protocol wherein a node of said plurality of nodes is capable of assigning itself a time slot from said time multiplex structure;determining a set of available time slots that are suitable for reception by said node of a communication from a neighboring node; andassigning to said node a receive slot from said set of available time slots, said receive slot having been assigned by said node;wherein said determining step comprises excluding from said set of available time slots those time slots in which a neighbor of said neighboring node is receiving. 9. The method of claim 8, wherein said time multiplex structure comprises a plurality of code division multiple access channels. 10. The method of claim 8, further comprising a scheduling step using a scheduling technique to coordinate communication. 11. The method of claim 8, wherein said determining step further comprises excluding from said set of available time slots those time slots that have been assigned to a neighbor of said node of said plurality of said nodes. 12. The method of claim 11, wherein said determining step further comprises excluding from said set of available time slots those time slots that have been assigned to said node of said plurality of said nodes. 13. The method of claim 8, further comprising the step of using said receive slot, by said node, to receive a communication from at least one neighboring node of said node of said plurality of nodes. 14. A method of managing communication resources to permit receiver-directed receive slot allocation in a network having a plurality of nodes, each node communicati ng during specific time slots on a time multiplex basis, the method comprising:establishing a network comprising a plurality of nodes, wherein network communication is accomplished via assignment of specific time slots of a time multiplex structure, said plurality of nodes participating in a dynamic assignment protocol wherein a node of said plurality of nodes is capable of assigning itself a time slot from said time multiplex structure;determining a set of available time slots that are suitable for reception by said node of a communication from a neighboring node;assigning to said node a receive slot from said set of available time slots, said receive slot having been assigned by said node; andusing said receive slot, by said node, to receive a communication from at least one neighboring node of said node of said plurality of nodes. 15. The method of claim 14, wherein said time multiplex structure comprises a time division multiple access protocol. 16. The method of claim 14, wherein said time multiplex structure further comprises a plurality of frequency channels. 17. The method of claim 14, further comprising a scheduling step using a scheduling technique to coordinate communication. 18. The method of claim 14, wherein said determining step comprises excluding from said set of available time slots those time slots in which a neighbor of said neighboring node is receiving. 19. The method of claim 14, wherein said time multiplex structure further comprises a plurality of code division multiple access channels and wherein said using step comprises a code division multiple access technique enabling simultaneous reception of communications by said dynamic node. 20. The method of claim 19, wherein said receive slot is a broadcast receive slot, and further wherein said node has knowledge of possible spreading codes that can be used by said at least one neighboring node when communicating in said broadcast receive slot.
