Abstract

In some implementations, a radio access provider, e.g., of a wireless telecommunications network, can receive, in a first frequency sub-band, control information of a first network. The provider can transmit, in a second sub-band, control information of a second network. The provider can transmit media information of the first network via first and second first-network channels in a third sub-band and transmit media information of the second network via a second-network channel arranged in frequency between the first and second first-network channels. In some implementations, the provider can select a first channel of the first network for first media; select a second channel of the second network for second media; select additional channels of the first network different in frequency from the second channel; and operate a first transceiver to wirelessly transmit the first media via the first channel and the additional channels.

Claims

1. A radio access provider, comprising:

one or more processing unit(s); and

one or more computer-readable media having thereon instructions executable to cause the processing unit(s) to perform operations comprising;

receiving, in a first frequency sub-band, control information of a first network having a first type;

transmitting, in a second, different frequency sub-band, control information of a second network having a second, different type;

transmitting media information of the first network via first and second first-network channels spaced apart in frequency within a third frequency sub-band; and

transmitting media information of the second network via a second-network channel arranged in frequency between the first and second first-network channels within the third frequency sub-band.

2. The radio access provider according to claim 1, wherein the operations further comprise:

selecting the first first-network channel randomly from a plurality of candidate channels of the first network.

3. The radio access provider according to claim 1, wherein the operations further comprise:

selecting, as the second first-network channel, one of a plurality of candidate channels closest to the first first-network channel and having a signal-quality value meeting a selected criterion.

4. The radio access provider according to claim 1, wherein the operations further comprise:

selecting, as the first first-network channel, one of a plurality of candidate channels most different in frequency from the second-network channel.

5. The radio access provider according to claim 1, wherein the operations further comprise:

determining respective channel quality values for individual candidate first-network channels based at least in part on second-network usage data of the candidate first-network channels; and

selecting the first first-network channel from the candidate first-network channels based at least in part on the channel quality values.

6. The radio access provider according to claim 5, wherein the operations further comprise:

receiving a device-specific channel quality value from a wireless communication device of the first network; and

determining at least one of the channel quality values further based on the device-specific channel quality value.

7. The radio access provider according to claim 1, wherein the operations further comprise:

after transmitting the media information of the first network via the first and second first-network channels, transmitting second media information of the first network via a third first-network channel within the third frequency sub-band different from the first and second first-network channels.

8. The radio access provider according to claim 1, wherein the operations further comprise:

detecting interference in transmissions of the second network; and

in response, reducing a reference-signal power of the first network.

9. The radio access provider according to claim 1, wherein the third frequency sub-band is disjoint from the second frequency sub-band.

10. The radio access provider according to claim 1, wherein the first type is an LTE type and the second type is a GSM type.

11. A radio access provider, comprising:

a first radio and a second, different radio, wherein the first radio and the second radio are tuned to operate within a common frequency band;

one or more antennas connected to at least the first radio or the second radio; and

a processor communicatively connected with the first radio and the second radio and configured to perform operations comprising;

receiving, via the first radio and in a first frequency sub-band, control information of a first network having a first type;

transmitting, via the second radio and in a second, different frequency sub-band, control information of a second network having a second, different type;

transmitting, via the first radio, media information of the first network via first and second first-network channels spaced apart in frequency within a third frequency sub-band; and

transmitting, via the second radio, media information of the second network via a second-network channel arranged in frequency between the first and second first-network channels within the third frequency sub-band.

12. The radio access provider according to claim 11, wherein the operations further comprise:

selecting the first first-network channel randomly from a plurality of candidate channels of the first network.

13. The radio access provider according to claim 11, wherein the operations further comprise:

selecting, as the first first-network channel, one of a plurality of candidate channels most different in frequency from the second-network channel.

14. The radio access provider according to claim 11, wherein the operations further comprise:

after transmitting the media information of the first network via the first and second first-network channels, transmitting second media information of the first network via a third first-network channel within the third frequency sub-band different from the first and second first-network channels.

15. The radio access provider according to claim 11, wherein the operations further comprise:

determining the first frequency sub-band closer to the center of a common band than the second frequency sub-band;

selecting the first first-network channel randomly from a plurality of candidate channels of the first network.

determining respective channel quality values for individual candidate first-network channels based at least in part on second-network usage data of the candidate first-network channels; and

selecting the second first-network channel from the candidate first-network channels based at least in part on the channel quality values.

16. A computer-implemented method, comprising:

selecting a first channel of a first network for first media information;

selecting a second channel of a second network for second media information;

selecting one or more additional channels of the first network for the first media information, each of the additional channels different in frequency from the second channel; and

operating a first transceiver to wirelessly transmit the first media information via the first channel and the one or more additional channels.

17. The computer-implemented method according to claim 16, further comprising operating a second, different transceiver to wirelessly transmit the second media information via the second channel.

18. The computer-implemented method according to claim 16, further comprising selecting the first channel randomly from a plurality of candidate channels of the first network.

19. The computer-implemented method according to claim 16, further comprising:

selecting a third channel of the second network, the third channel different in frequency from the second channel and at least partly overlapping in frequency with a conflict channel of the additional channels; and
