Channel aggregation

1. A method comprising:

transmitting first data on a first channel to a first wireless device, the first channel comprising multiple subchannels;

simultaneously transmitting second data on a second channel to the first wireless device such that the first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel;

receiving from the first wireless device third data on the first channel, the third data including at least one first automatic retransmit request (ARQ)-related number;

receiving from the first wireless device fourth data on the second channel, the fourth data including at least one second ARQ-related number;

combining the third data and the fourth data into integrated data; and

ordering the third data and the fourth data using at least the first ARQ-related number and the second ARQ-related number so as to restore a correct ordering for the integrated data;

wherein each of the first channel and the second channel is independently and properly formed so that a second wireless device that is unable to support channel aggregation is capable of communicating by independently using one of the first channel or the second channel.

2. A method comprising:

transmitting first data on a first channel to a first wireless device, the first channel comprising multiple subchannels;

simultaneously transmitting second data on a second channel to the first wireless device such that the first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel;

transmitting third data on the first channel to a second wireless device that is unable to support channel aggregation, wherein the third data is unrelated to any channel aggregation communications; and

switching from a first transmission mode that supports channel aggregation to a second transmission mode that does not support channel aggregation between the transmitting first data and the transmitting third data;

wherein each of the first channel and the second channel is independently and properly formed so that the second wireless device is capable of communicating by independently using one of the first channel or the second channel.

3. A method comprising:

transmitting, by a base transceiver station, first data on a licensed communications channel to a first wireless device, wherein a first channel includes the licensed communications channel and multiple subchannels;

simultaneously transmitting, by a first access point, second data on a non-exclusively-licensed channel to the first wireless device, wherein a second channel includes the non-exclusively-licensed channel, such that the first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel; and

simultaneously transmitting, by a second access point, the second data on the second channel;

wherein each of the first channel and the second channel is independently and properly formed so that a second wireless device that is unable to support channel aggregation is capable of communicating by independently using one of the first channel or the second channel.

4. The method of claim 3 , wherein:

the base transceiver station is associated with a first communication region, the first access point is associated with a second communication region, and the second access point is associated with a third communication region; and wherein the second and third communication regions separately overlay at least part of the first communication region.

5. A method comprising

transmitting first data on a first channel to a first wireless device, wherein the first channel comprises a licensed channel; and

simultaneously transmitting second data on a second nonadjacent channel to the first wireless device such that the first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second nonadjacent channel, wherein the second nonadjacent channel comprises a non-exclusively-licensed channel;

allocating data communications to the second nonadjacent channel; and

allocating automatic retransmit request (ARQ)-related communications to the first channel;

wherein each of the first channel and the second nonadjacent channel is independently and properly formed so that a second wireless device that is unable to support channel aggregation is capable of communicating by independently using one of the first channel or the second nonadjacent channel.

6. A method comprising:

transmitting first data on a first channel to a first wireless device; and

simultaneously transmitting second data on a second nonadjacent channel to the first wireless device such that the first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second nonadjacent channel;

allocating data destined for a mobile wireless device to a licensed communication channel; and

allocating data destined for a stationary wireless device to a non-exclusively-licensed communications channel;

wherein each of the first channel and the second nonadjacent channel is independently and properly formed so that a second wireless device that is unable to support channel aggregation is capable of communicating by independently using one of the first channel or the second nonadjacent channel.
