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.
Claims24
A method for wireless communication in a wireless network, the method comprising:
- transmitting first downlink information on a first frequency channel to one or more frequency domain duplex (FDD) user equipments (UEs);
- transmitting second 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 transmissions;
- and
- controlling the uplink transmissions from the FDD UEs to occur only during uplink portions of the TDD frame periods of the second frequency channel, wherein each downlink portion of each 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.

A method for wireless communication in a wireless network, the method comprising:
- receiving first uplink information on a first frequency channel from one or more frequency domain duplex (FDD) user equipments (UEs);
- receiving second uplink information on a second frequency channel during uplink portions of time domain duplex (TDD) frame periods of the second frequency channel from one or more TDD UEs, wherein the second frequency channel is a frequency channel on which the FDD UEs are configured to receive downlink transmissions;
- and
- transmitting downlink information to the one or more FDD UEs on the second frequency channel only during downlink portions of the TDD frame periods, wherein each downlink portion of each 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.

- transmit second 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 transmissions;
- and
- control the uplink transmissions from the FDD UEs to occur only during uplink portions of the TDD frame periods of the second frequency channel, wherein each downlink portion of each TDD frame period is separated from an adjacent uplink portion of the second frequency channel by an intra-frame guard time or an inter-frame guard time;
- and
- a processor communicatively coupled to the non-transitory signal bearing medium to execute the instructions.
