Abstract

A duplex frequency is supplemented by providing simplex frequencies and distributing a data load among them. A server initially communicates with a communications device using a duplex channel. A scheduler of the server determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and the simplex channels. Before sending this data through multiple channels, the server first sends a schedule to the communications device to inform which bits of data are coming through which channels at which times. The scheduler compiles this schedule and sends it to the communications device through the duplex channel. A descheduler within the communications device receives the schedule and alerts the communications device to start receiving data on other simplex channels. The descheduler then puts the bits of data in order as they stream in across the duplex and simplex channels.

Claims

1. A method, comprising:

receiving, by a system comprising a processor, information indicative of a distribution of data packets between an anchor channel, utilized for duplex transmission, and a simplex channel, utilized for simplex transmission; and

receiving, by the system, a first portion of the data packets via the anchor channel and receiving a second portion of the data packets via the simplex channel, and wherein the receiving the first portion and the second portion of the data packets is performed via asymmetrical multicarrier communication.

2. The method of claim 1, wherein the receiving the information comprises receiving the information prior to the receiving the first portion of the data packets.

3. The method of claim 2, wherein the receiving the information comprises receiving the information prior to the receiving the second portion of the data packets.

4. The method of claim 1, wherein the receiving the information comprises receiving timing information associated with times of receipt of the data packets.

5. The method of claim 1, wherein the receiving the information comprises receiving frequency information associated with a frequency of receipt of the data packets.

6. The method of claim 1, further comprising:

transmitting, by the system, a request for the data packets via the anchor channel.

7. The method of claim 1, wherein the distribution of the data packets is a first distribution of first data packets of the data packets, and the method further comprises:

transmitting, by the system, feedback information utilized to determine a second distribution of second data packets of the data packets.

8. The method of claim 7, wherein the feedback information is utilized to balance a second distribution of second data packets between the anchor channel and the simplex channel.

9. The method of claim 1, further comprising:

selecting, by the system, frequencies associated with the anchor channel based on a distance between the system and an access point device.

10. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

receiving schedule information indicative of a distribution of data packets between an anchor channel, utilized for duplex transmission, and a simplex channel, utilized for simplex transmission; and

receiving the data packets via asymmetrical multicarrier communication comprising receiving a first portion of the data packets via the anchor channel and receiving a second portion of the data packets via the simplex channel.

11. The system of claim 10, wherein the receiving the schedule information comprises receiving the schedule information prior to the receiving the first portion of the data packets and the receiving the second portion of the data packets.

12. The system of claim 10, wherein the operations further comprise:

identifying a channel on which a portion of the data packets is to be received at a specified time, based on the schedule information.

13. The system of claim 10, wherein the receiving the schedule information comprises receiving timing information associated with a time of receipt of a data packet of the data packets.

14. The system of claim 10, wherein the receiving the schedule information comprises receiving frequency information associated with a frequency receipt of the data packets.

15. The system of claim 10, wherein the operations further comprise:

transmitting a request for the data packets via the anchor channel.

16. The system of claim 10, wherein the distribution of the data packets is a first distribution of first data packets, and the operations further comprise:

transmitting feedback information associated with the data packets, wherein the feedback information comprises feedback information about a quality of the data packets.

17. The system of claim 16, wherein the feedback information is utilized to determine a second distribution of second data packets between the anchor channel and the simplex channel.

18. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

receiving schedule information indicative of a distribution of data packets between an anchor channel, utilized for duplex transmission, and a simplex channel, utilized for simplex transmission;

receiving a first portion of the data packets via the anchor channel via asymmetrical multicarrier communication; and

receiving a second portion of the data packets via the simplex channel via the asymmetrical multicarrier communication.

19. The machine-readable storage medium of claim 18, wherein the receiving the schedule information comprises receiving the schedule information prior to the receiving the first portion of the data packets and the receiving the second portion of the data packets.

20. The machine-readable storage medium of claim 18, wherein the operations further comprise:

identifying a channel on which a portion of the data packets is to be received at a specified time, based on the schedule information.
