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:

generating, by a system comprising a processor, feedback information regarding a first portion of data packets via a first anchor channel of anchor channels and a second portion of the data packets via a simplex channel, wherein the feedback information facilitates a balancing of transmissions between the anchor channel and the simplex channel; and

selecting, by the system, a second anchor channel of the anchor channels, at a time of transmission of the data packets, to use for receipt of a group of the data packets, wherein the second anchor channel to be used for receipt of the group of the data packets is selected based on a load at the time of transmission of the data packets.

2. The method of claim 1, further comprising receiving, by the system, timing information associated with times of receipt of the data packets and wherein the load comprises a load of an application.

3. The method of claim 1, further comprising receiving, by the system, frequency information associated with a frequency of receipt of the data packets.

4. The method of claim 1, further comprising:

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

5. The method of claim 1, further comprising:

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

6. A system, comprising:

a processor; and

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

in response to a determination by the system that an estimated load of an application satisfies a defined condition, obtaining data packets via asymmetrical multicarrier communication;

determining 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

transmitting, to a server device, feedback relating to a first portion of the data packets and a second portion of the data packets to facilitate a balancing of transmissions between the anchor channel and the simplex channel.

7. The system of claim 6, wherein the feedback is associated with a first quality of the first portion and a second quality of the second portion.

8. The system of claim 6, wherein the schedule information is based on the estimated load of the application with which the data packets are associated.

9. The system of claim 6, wherein the obtaining the data packets via the asymmetrical multicarrier communication comprises obtaining the first portion of the data packets via the anchor channel and obtaining the second portion of the data packets via the simplex channel.

10. The system of claim 6, wherein the determining the schedule information comprises determining the schedule information prior to obtaining the first portion of the data packets and prior to obtaining the second portion of the data packets.

11. The system of claim 6, wherein the operations further comprise:

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

12. The system of claim 6, wherein the determining the schedule information comprises determining timing information associated with a time of obtaining a data packet of the data packets.

13. The system of claim 6, wherein the determining the schedule information comprises determining frequency information associated with a frequency of obtaining of packets of the data packets.

14. The system of claim 6, wherein the operations further comprise:

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

15. A non-transitory machine-readable 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; and

transmitting, to a server device, feedback relating to a first portion of the data packets and a second portion of the data packets to facilitate balancing transmissions across the anchor channel and the simplex channel, wherein the first portion and the second portion are received via asymmetrical multicarrier communication and in response to a determination that an estimated load of an application has satisfied a defined condition.

16. The non-transitory machine-readable medium of claim 15, wherein the feedback is associated with a first quality of the first portion and a second quality of the second portion.

17. The non-transitory machine-readable medium of claim 15, wherein the schedule information is based on the estimated load of the application, and wherein the data packets are associated with the application.

18. The non-transitory machine-readable medium of claim 15, wherein the operations further comprise:

identifying a channel on which some of the data packets are to be received at a specified time or frequency.

19. The non-transitory The machine-readable medium of claim 15, wherein the operations further comprise:

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

20. The non-transitory machine-readable medium of claim 15, wherein the operations further comprise:

selecting frequencies associated with the first anchor channel based on a distance between a system comprising the processor and an access point device.
