Communication resource allocation systems and methods

摘要

A channel descriptor management message is transmitted on a broadcast connection to a mobile terminal. The channel descriptor management message provides a format for a frame. The frame includes a resource space. The channel descriptor management message defines a plurality of channels within the resource space and allocates at least one of the channels to a plurality of users. Subsequent resource allocation messages may refer to a location within a channel rather than a location within the entire resource space.

1. A method for allocating a downlink OFDM resource space, the method comprising:
transmitting a channel descriptor management message, the channel descriptor management message providing a format for a transmission unit, the transmission unit including an OFDM resource space, said channel descriptor management message providing a definition for a plurality of sub-resource spaces within the OFDM resource space, each sub-resource space having an associated sub-resource space identifier and being individually allocatable; and transmitting a transmission unit, the transmission unit comprising:
for each of at least one receiver, a respective sub-burst within at least one of the plurality of sub-resource spaces within the OFDM resource space; anda downlink mapping component that includes information for each receiver indicating where the respective sub-burst for the receiver is located in the OFDM resource space, wherein the information for each receiver associates the sub-resource space identifier that is associated with the sub-resource space in which the receiver's sub-burst is located with a connection identifier that the receiver looks for.
