Apparatuses, systems, and methods for reducing spurious emissions resulting from carrier leakage

1. An apparatus comprising:

a modulator configured to modulate a data signal onto a carrier signal to generate a modulated signal having a transmit frequency within a predefined frequency range adjacent to and within a boundary of an uplink frequency band, said carrier signal having a carrier frequency;

a filter configured to at least partially remove a carrier frequency component from said modulated signal to produce a filtered modulated signal;

an antenna configured to transmit said filtered modulated signal; and

a switch facility communicatively coupled to said filter;

wherein said modulator is further configured to modulate another data signal onto another carrier signal to generate another modulated signal having a transmit frequency within said uplink frequency band and outside said predefined frequency range, said another carrier signal having said carrier frequency; and

wherein said switch facility is configured to selectively disable said filter to prevent said filter from removing a carrier frequency component from said another modulated signal.

2. The apparatus of claim 1 , wherein said another data signal comprises a physical uplink shared channel signal.

3. The apparatus of claim 1 , wherein said antenna is further configured to transmit said another modulated signal.

4. The apparatus of claim 1 , wherein said filter is configured to reduce at least one intermodulation product resulting from carrier leakage associated with said carrier signal.

5. The apparatus of claim 1 , wherein said data signal comprises a control data signal.

6. The apparatus of claim 1 , wherein said data signal comprises a physical uplink control channel signal.

7. The apparatus of claim 1 , wherein said uplink frequency band is adjacent to a downlink frequency band.

8. The apparatus of claim 1 , further comprising a power amplifier configured to amplify said filtered modulated signal prior to transmission of said filtered modulated signal by said antenna.

9. The apparatus of claim 1 , wherein said filter comprises a trap filter.

10. The apparatus of claim 1 , wherein said filter comprises a band-pass filter.

11. The apparatus of claim 1 , wherein said predefined frequency range comprises one or more resource blocks allocated for transmission of one or more control data signals.

12. The apparatus of claim 1 , wherein said carrier frequency is outside of said predefined frequency band.

13. A system comprising:

a processing facility configured to generate a first data signal and a second data signal; and

a transmitter facility communicatively coupled to said processing facility, said transmitter facility configured to

modulate said first data signal onto a carrier signal to generate a modulated first signal having a transmit frequency within a predefined frequency range adjacent to and within a boundary of an uplink frequency band, said carrier signal having a carrier frequency,

modulate said second data signal onto another carrier signal to generate a modulated second signal having a transmit frequency within said uplink frequency band and outside said predefined frequency range, said another carrier signal having said carrier frequency,

at least partially remove a carrier frequency component from said modulated first signal to produce a filtered modulated first signal, and

transmit said filtered modulated first signal and said modulated second signal.

14. The system of claim 13 , wherein said first data signal comprises a physical uplink control channel signal and said second data signal comprises a physical uplink shared channel signal.

15. The system of claim 13 , wherein said uplink frequency band is adjacent to a downlink frequency band.

16. The system of claim 13 , wherein said carrier frequency is outside of said predefined frequency band.

17. A method comprising:

generating a first modulated signal having a transmit frequency within a predefined frequency range adjacent to and within a boundary of an uplink frequency band;

generating a second modulated signal having a transmit frequency within said uplink frequency band and outside said predefined frequency range;

enabling a filter to selectively remove a carrier frequency component from said first modulated signal; and

disabling said filter to prevent said filter from removing a carrier frequency component from said second modulated signal.

18. The method of claim 17 , further comprising transmitting said filtered first modulated signal and said second modulated signal.

19. The method of claim 17 , wherein said first modulated signal comprises a control data signal and said second modulated signal comprises a content data signal.
