Wireless communication
View Patent ↗Communication apparatus, method and computer program product for communication in a communication system. While a transmitter of a transceiver module of a user equipment is transmitting, a first receiver is operated on a first received signal, and a second receiver is operated on a transmitted signal from the transmitter. While the transmitter is not transmitting, the second receiver is operated on a second received signal.
1. An apparatus comprising:
a transmitter;
a first receiver;
a second receiver;
and
circuitry configured to:
while the transmitter is transmitting:
operate the first receiver on a first received signal; and
operate the second receiver on a signal transmitted from the transmitter;
while the transmitter is not transmitting:
operate the second receiver on a second received signal;
apply a first attenuation to the signal received by the second receiver when operating on the transmitted signal; and
apply a second attenuation when operating on the second received signal, the second attenuation being lower than the first attenuation.
2. The apparatus of claim 1 , wherein
the first receiver comprises a main receiver and the second receiver comprises a measurement receiver.
3. The apparatus of claim 1 , wherein
the first received signal is received in a downlink operating band.
4. The apparatus of claim 3 , wherein
the first received signal originates from a base station.
5. The apparatus of claim 1 , wherein the second received signal is received in an uplink operating band.
6. The apparatus of claim 5 , wherein
the second received signal originates from a user equipment.
7. The apparatus of claim 1 , further comprising:
a directional coupler, wherein
the signal to the second receiver passes through the directional coupler.
8. The apparatus of claim 1 , wherein
operating the second receiver on the signal transmitted from the transmitter comprises at least one of antenna tuning and predistortion setting.
9. The apparatus of claim 1 , wherein
operating the second receiver on a second received signal comprises at least one of reception of discovery signals and device-to-device transmissions.
10. A non-transitory computer-readable storage medium having computer readable instructions stored thereon, the computer readable instructions being executable by a computerized device to cause the computerized device to:
while a transmitter is transmitting:
operate a first receiver on a first received signal; and
operate a second receiver on a signal transmitted from the transmitter, and
while the transmitter is not transmitting:
operate the second receiver on a second received signal, wherein
a first attenuation is applied to the signal received by the second receiver when operating on the transmitted signal, and a second attenuation, which is lower than the first attenuation, is applied when operating on the second received signal, and
the transmitter, first receiver and second receiver are comprised within a single transceiver module within the computerized device.
11. The apparatus of claim 1 , wherein
the circuitry is configured to operate the second receiver only on a signal transmitted from the transmitter while the transmitter is transmitting.
12. A method for use in wireless communication, the method comprising:
while a transmitter is transmitting:
operating a first receiver on a first received signal; and
operating a second receiver on a signal transmitted from the transmitter, and
while the transmitter is not transmitting:
operating the second receiver on a second received signal, wherein
a first attenuation is applied to the signal received by the second receiver when operating on the transmitted signal, and a second attenuation, which is lower than the first attenuation, is applied when operating on the second received signal, and
the transmitter, first receiver and second receiver are comprised within a single transceiver module.
13. The method of claim 12 , wherein
the first receiver comprises a main receiver and the second receiver comprises a measurement receiver.
14. The method of claim 12 , wherein
the first received signal is received in a downlink operating band.
15. The method of claim 14 , wherein
the first received signal originates from a base station.
16. The method of claim 12 , wherein
the second received signal is received in an uplink operating band.
17. The method of claim 16 , wherein
the second received signal originates from a user equipment.
18. The method of claim 12 , wherein
the signal to the second receiver passes through a directional coupler.
19. The method of claim 12 , wherein
operating the second receiver on the signal transmitted from the transmitter comprises at least one of antenna tuning and predistortion setting.
20. The method of claim 12 , wherein
operating the second receiver on a second received signal comprises at least one of reception of discovery signals and device-to-device transmissions.
21. The apparatus of claim 1 , wherein
the apparatus is a user equipment, and
the second received signal is a signal received from another user equipment while participating in device-to-device communications.
