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 (42)

1. An apparatus for wireless communication in a wireless network, the apparatus comprising:

a transceiver configured to connect to one or more antennas; and

a wireless communication management processor communicatively coupled to the transceiver, wherein the wireless communication management processor is configured to control performance of the transceiver to:

receive first downlink data, at a frequency domain duplex (FDD) user equipment, on a first frequency channel; and

transmit uplink data, from the FDD user equipment, during one or more uplink portions of one or more time domain duplex (TDD) frame periods of a second frequency channel, on the second frequency channel,

wherein the second frequency channel is a channel on which one or more TDD user equipment are configured to receive second downlink data during one or more downlink portions of the one or more TDD frame periods of the second frequency channel, and

wherein at least one downlink portion of at least one TDD frame period of the second frequency channel is separated from an adjacent uplink portion of the second frequency channel by an intra-frame guard time or an inter-frame guard time.

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

3. The apparatus of claim 1 , wherein the wireless network includes a cellular network.

4. The apparatus of claim 1 , wherein the FDD user equipment includes a headset.

5. The apparatus of claim 1 , wherein the FDD user equipment includes a mobile phone.

6. The apparatus of claim 1 , wherein the uplink data is transmitted by virtue of adherence to one or more interoperation standards, and wherein the one or more interoperation standards include 3rd generation partnership project (3GPP).

7. The apparatus of claim 1 , wherein the uplink data is transmitted by virtue of adherence to one or more interoperation standards, and wherein the one or more interoperation standards include long term evolution (LTE).

8. An apparatus for wireless communication in a wireless network, the apparatus comprising:

a transceiver configured to connect to one or more antennas; and

a wireless communication management processor communicatively coupled to the transceiver, wherein the wireless communication management processor is configured to control performance of the transceiver to:

receive downlink data, at a frequency domain duplex (FDD) user equipment, during one or more downlink portions of one or more time domain duplex (TDD) frame periods of a first frequency channel, on the first frequency channel; and

transmit first uplink data, from the FDD user equipment, on a second frequency channel,

wherein the first frequency channel is a channel on which one or more TDD user equipment are configured to transmit second uplink data during one or more uplink portions of the one or more TDD frame periods of the first frequency channel, and

wherein at least one downlink portion of at least one TDD frame period of the first frequency channel is separated from an adjacent uplink portion of the first frequency channel by an intra-frame guard time or an inter-frame guard time.

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

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

11. The apparatus of claim 8 , wherein the FDD user equipment includes a headset.

12. The apparatus of claim 8 , wherein the FDD user equipment includes a mobile phone.

13. The apparatus of claim 8 , wherein the first uplink data is transmitted by virtue of adherence to one or more interoperation standards, and wherein the one or more interoperation standards include 3rd generation partnership project (3GPP).

14. The apparatus of claim 8 , wherein the first uplink data is transmitted by virtue of adherence to one or more interoperation standards, and wherein the one or more interoperation standards include long term evolution (LTE).

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

receiving first downlink data, at a frequency domain duplex (FDD) user equipment, on a first frequency channel; and

transmitting uplink data, from the FDD user equipment, during one or more uplink portions of one or more time domain duplex (TDD) frame periods of a second frequency channel, on the second frequency channel,

wherein the second frequency channel is a channel on which one or more TDD user equipment are configured to receive second downlink data during one or more downlink portions of the one or more TDD frame periods of the second frequency channel, and

wherein at least one downlink portion of at least one TDD frame period of the second frequency channel is separated from an adjacent uplink portion of the second frequency channel by an intra-frame guard time or an inter-frame guard time.

16. The method of claim 15 , wherein the wireless network includes a long term evolution (LTE) wireless network.

17. The method of claim 15 , wherein the wireless network includes a cellular network.

18. An apparatus for wireless communication in a wireless network, the apparatus comprising:

a transceiver configured to connect to one or more antennas; and

a wireless communication management processor communicatively coupled to the transceiver, wherein the wireless communication management processor is configured to control performance of the transceiver to:

receive downlink data, at a time domain duplex (TDD) user equipment, during one or more downlink portions of one or more TDD frame periods of a hybrid frequency channel, on the hybrid frequency channel; and

transmit first uplink data, from the TDD user equipment, during one or more uplink portions of the one or more TDD frame periods of the hybrid frequency channel, on the hybrid frequency channel,

wherein the hybrid frequency channel is a channel on which one or more frequency domain duplex (FDD) user equipment are configured to transmit second uplink data during the one or more uplink portions of the one or more TDD frame periods of the hybrid frequency channel, and

wherein at least one downlink portion of at least one TDD frame period of the hybrid frequency channel is separated from an adjacent uplink portion of the hybrid frequency channel by an intra-frame guard time or an inter-frame guard time.

19. The apparatus of claim 18 , wherein the TDD user equipment includes a headset.

20. The apparatus of claim 18 , wherein the TDD user equipment includes a mobile phone.
