Patent Images
1. A method of allocating transmission resources in a wireless communications system, the method comprising the steps of:
- providing a physical layer packet format data;
providing the physical layer packet format data to a communication station via a traffic channel;
providing an access network;
utilizing the access network to assign a plurality of access terminals with a single channel node having at least one base node;
utilizing the access network to assign a short ID to each access terminal of the plurality of access terminals, wherein the assignment is dynamic;
utilizing the access network to schedule at least one access terminal, and a payload for the at least one access terminal into a physical layer packet; and
transmitting the physical layer packet in a first interlace to the scheduled at least one access terminal, wherein the access network signals the plurality of access terminals a timing information of a new second interlace, and wherein the timing information is placed in a first subcarrier of a first symbol of each traffic frame.
