Channel interference reduction
View Patent ↗A method for data transmission over first and second media that overlaps in frequency includes computing one or more time division multiple access (TDMA) time-slot channels to be shared between the first and second media for data transmission; allocating one or more time-slot channels to the first medium for data transmission; allocating one or more of the remaining time-slot channels to the second medium for data transmission; and instructing transceivers for the first and second media to communicate only in their allocated time-slot channels.
1. A method comprising:
a base station allocating at least one of a plurality of data channels to a first medium for data transmission via a wireless device;
the base station allocating at least one remaining data channel of the plurality of data channels to a second medium for data transmission via the wireless device; and
the base station dynamically adjusting, during data transmission, a number of the data channels assigned to one of the first and second media to remain within limits of a desired level of service.
2. The method of claim 1 , further comprising the base station computing one or more time division multiple access (TDMA) time-slot channels to be shared between the first medium and the second medium for data transmission.
3. The method of claim 1 , wherein at least one of the first and second media conforms to an 802.11 specification.
4. The method of claim 1 , wherein at least one of the first and second media conforms to a Bluetooth specification.
5. The method of claim 1 , further comprising the base station determining the desired level of service for one of the first and second media during data transmission.
6. The method of claim 1 , wherein the dynamic adjusting comprises:
the base station determining available data channels;
the base station detecting a medium that fails to meet the desired level of service;
the base station allocating one or more additional channels to the detected medium; and
the base station transmitting a channel assignment message including information on the allocated configuration with the additional data channels.
7. The method of claim 6 , further comprising the base station instructing transceivers for the first and second media to communicate in their additional allocated data channels and to not communicate using other data channels.
8. The method of claim 1 , wherein the data channels comprise time division multiple access (TDMA) channels.
9. The method of claim 1 , wherein the wireless device is configured to transmit on bonded cellular frequency channels.
10. The method of claim 9 , further comprising the base station allocating uplink and downlink cellular frequency channels separately.
11. The method of claim 8 , further comprising the base station instructing transceivers for the first and second media to communicate in their allocated time-slot channels and not using other channels.
12. A system comprising:
a processor;
a first transceiver configured to communicate via a first medium;
a second transceiver configured to communicate via a second medium, wherein at least one of the first transceiver and the second transceiver is configured to retry transmission of a packet at a lower rate if a prior transmission of the packet is not acknowledged;
an allocation unit configured to dynamically allocate data channels to one of the first medium and the second medium based upon a desired level of service.
13. The system of claim 12 , wherein the processor comprises an integrated circuit having a reconfigurable processor core that includes a plurality of digital signal processors (DSPs).
14. The system of claim 13 , wherein the integrated circuit further comprises a router coupled to the reconfigurable processor core.
15. The system of claim 14 , wherein the router is configured to bond a plurality of cellular frequency channels and at least one short-range wireless channel.
16. The system of claim 12 , wherein the allocation unit is further configured to select one of the first medium and the second medium as a common medium for data transmission.
17. The method of claim 1 , wherein the first and second media are wireless communication media for transmitting data, and wherein the first and second media share overlapping frequency bands.
18. An apparatus, comprising:
a means for allocating at least a first data channel of a plurality of data channels to be shared between a first medium and a second medium, to the first medium for data transmission via a wireless device, and for allocating at least a second data channel of the plurality of data channels to the second medium for data transmission via the wireless device; and
a means for dynamically adjusting a number of the data channels assigned to one of the first and second media during the data transmission to remain within limits of a desired level of service.
19. The apparatus of claim 18 , wherein the means for dynamically adjusting includes means for determining available data channels, detecting a medium that fails to meet the desired level of service, allocating the medium to a configuration having additional data channels, and transmitting a channel assignment message including information on the allocated configuration with the additional data channels.
20. The apparatus of claim 18 , wherein the means for allocating includes a means for computing one or more time division multiple access (TDMA) time-slot channels to be shared between the first medium and the second medium for data transmission.
