Abstract

Technologies and implementations for wireless communication in a wireless network including transmitting downlink information on a first frequency channel to Frequency Division Duplexing (FDD) User Equipments (UEs), transmitting downlink information on a second frequency channel during downlink portions of Time Domain Duplex (TDD) frame periods of the second frequency channel to TDD UEs, wherein the second frequency channel is the same as the frequency channel on which the FDD UEs are configured to transmit, and controlling uplink transmissions from the FDD UEs to occur only during uplink portions of TDD frame periods of the second frequency channel.

Claims (38)

1. A method for wireless communication in a wireless network, the method comprising:

transmitting downlink information on a first frequency channel to one or more frequency domain duplex (FDD) user equipments (UEs);

transmitting downlink information on a second frequency channel during downlink portions of time domain duplex (TDD) frame periods of the second frequency channel to one or more TDD UEs, wherein the second frequency channel is a frequency channel on which the FDD UEs are configured to transmit uplink information; and

controlling uplink transmissions, to transmit the uplink information on the second frequency channel, from the FDD UEs to occur during uplink portions of the TDD frame periods of the second frequency channel, wherein the uplink portions, during which the FDD UEs transmit the uplink information, are distinct from the downlink portions, during which the TDD UEs receive the downlink information, of the TDD frame periods.

2. The method of claim 1 , further comprising:

prior to transmitting the downlink information on the second frequency channel, reconfiguring the frequency channel on which the FDD UEs are configured to transmit the uplink information as the second frequency channel.

3. The method of claim 1 , further comprising:

dynamically modifying at least one of a time interval of the TDD frame periods, a time interval of the downlink portions of the TDD frame periods, or a time interval of the uplink portions of the TDD frame periods.

4. The method of claim 1 , wherein the wireless network includes a long term evolution (LTE) wireless network.

5. The method of claim 1 , wherein the wireless network includes a cellular network.

6. The method of claim 1 , wherein at least one of the FDD UEs includes a headset.

7. The method of claim 1 , wherein at least one of the FDD UEs includes a mobile phone.

8. An apparatus for wireless communication, the apparatus comprising:

a transceiver operable to establish a communication like with one or more antennas;

a processor coupled to the transceiver; and

a non-transitory computer-readable medium coupled to the processor and having instructions stored thereon, which in response to execution by the processor, cause the processor to perform or control performance of operations that include:

transmit, via the transceiver, downlink information on a first frequency channel to one or more frequency domain duplex (FDD) user equipments (UEs);

transmit, via the transceiver, downlink information on a second frequency channel during downlink portions of time domain duplex (TDD) frame periods of the second frequency channel to one or more TDD UEs, wherein the second frequency channel is a frequency channel on which the FDD UEs are configured to transmit uplink information; and

control uplink transmissions, to transmit the uplink information on the second frequency channel, from the FDD UEs to occur during uplink portions of the TDD frame periods of the second frequency, wherein the uplink portions, during which the FDD UEs transmit the uplink information, are distinct from the downlink portions, during which the TDD UEs receive the downlink information, of the TDD frame periods.

9. The apparatus of claim 8 , wherein the operations further comprise:

prior to transmission of the downlink information on the second frequency channel, reconfigure the frequency channel on which the FDD UEs are configured to transmit the uplink information as the second frequency channel.

10. The apparatus of claim 8 , wherein the operations further comprise:

dynamically modify at least one of a time interval of the TDD frame periods, a time interval of the downlink portions of the TDD frame periods, or a time interval of the uplink portions of the TDD frame periods.

11. The apparatus of claim 8 , wherein the wireless network includes a long term evolution (LTE) wireless network.

12. The apparatus of claim 8 , wherein the wireless network includes a cellular network.

13. The apparatus of claim 8 , wherein at least one of the FDD UEs includes a headset.

14. The apparatus of claim 8 , wherein at least one of the FDD UEs includes a mobile phone.

15. A non-transitory computer-readable medium having instructions stored thereon, which in response to execution by a processor, cause the processor to perform or control performance of operations that include:

transmit downlink information on a first frequency channel to one or more frequency domain duplex (FDD) user equipments (UEs);

reconfigure a second frequency channel, on which the FDD UEs are configured to transmit uplink information, to transmit downlink information to one or more time domain duplex (TDD) UEs;

transmit the downlink information on the second frequency channel during downlink portions of TDD frame periods of the second frequency channel to the one or more TDD UEs; and

control uplink transmissions, to transmit the uplink information on the second frequency channel, from the FDD UEs to occur during uplink portions of the TDD frame periods of the second frequency channel, wherein the uplink portions, during which the FDD UEs transmit the uplink information, are distinct from the downlink portions, during which the TDD UEs receive the downlink information, of the TDD frame periods.

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

dynamically modify at least one of a time interval of the TDD frame periods, a time interval of the downlink portions of the TDD frame periods, or a time interval of the uplink portions of the TDD frame periods.

17. The non-transitory computer-readable medium of claim 15 , wherein the wireless network includes a long term evolution (LTE) wireless network.

18. The non-transitory computer-readable medium of claim 15 , wherein the wireless network includes a cellular network.

19. The non-transitory computer-readable medium of claim 15 , wherein at least one of the FDD UEs includes a headset.

20. The non-transitory computer-readable medium of claim 15 , wherein at least one of the FDD UEs includes a mobile phone.
