Method and apparatus for assigning receive slots in a dynamic assignment environment
First Claim
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; and
accessing using a random access technique to coordinate communication;
wherein said receive slot is a broadcast receive slot.

Abstract
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.
