Abstract

A method for receiving data packets in a communication network comprising scanning a channel for a preamble during an acquisition search window, detecting the preamble during the acquisition search window, assigning a reception acquisition search window for receipt of a data packet including a data preamble and a data portion, coordinating the transmission of the data packet with the reception acquisition search window, detecting the data preamble during the reception acquisition search window, and initiating receipt of the data portion upon detection of the data preamble.

Claims (25)

1. A method for receiving data packets in a communication network, comprising:

scanning a channel, by a receiver, for a preamble during an acquisition search window;

detecting the preamble during the acquisition search window;

assigning a reception acquisition search window for receipt of a data packet including a data preamble and a data portion;

coordinating the transmission of the data packet with the reception acquisition search window;

detecting the data preamble during the reception acquisition search window;

initiating receipt of the data portion upon detection of the data preamble;

wherein the acquisition search window is periodically repeated following a length comprising the sum of the acquisition search window and the preamble.

2. The method of claim 1 , wherein the preamble is a fused preamble to compensate for at least one of propagation delay and clock error.

3. The method of claim 1 , wherein a slot grant assigns the reception acquisition search window for receipt of the data packet.

4. The method of claim 3 , wherein the preamble and the slot grant are approximately the same length.

5. The method of claim 1 , wherein the length further comprises a processing time.

6. The method of claim 1 , wherein coordinating the transmission of the data packet comprises a propagation guard time.

7. The method of claim 1 , wherein at least one of the preamble or data are transmitted via a frequency-hopping pattern.

8. A computer-readable medium having computer-executable instructions for performing a method for receiving data packets in a communication network, the method comprising:

periodically scanning a channel, by a receiver, for a preamble during an acquisition search window;

detecting the preamble during the acquisition search window;

assigning a reception acquisition search window for receipt of a data packet including a data preamble and a data portion;

coordinating the transmission of the data packet with the reception acquisition search window;

detecting the data preamble during the reception acquisition search window;

initiating receipt of the data portion upon detection of the data preamble; and

wherein the acquisition search window is periodically repeated following a length comprising the sum of the acquisition search window and the preamble.

9. The computer-readable medium of claim 8 , wherein the preamble is a fused preamble to compensate for at least one of propagation delay and clock error.

10. The computer-readable medium of claim 8 , wherein coordinating the transmission of the data packet comprises a propagation guard time.

11. The computer-readable medium of claim 8 , wherein the preamble is transmitted via a frequency-hopping pattern.
