Abstract

A multi-mode wireless communications device (100) and methods therefor, including a first transceiver having a continuous reception mode receiver coupled to a first antenna (138) and a second transceiver having a second transmitter coupled to a second antenna (140). In one mode of operation, the continuous reception mode receiver receives an uncompressed downlink signal at the same time the other receiver receives a signal. In another mode of operation, the continuous reception mode receiver receives an uncompressed downlink signal at the same time a transmitter of the second transceiver transmits a signal. In another mode of operation, a continuous reception mode transmitter of the first transceiver transmits an uplink signal at the same time the other receiver receives a signal.

Claims

1. A wireless communication handset, comprising:

a first transceiver having a first receiver and a first transmitter;

a first antenna coupled to the first receiver;

a second transceiver having a second receiver and a second transmitter;

a second antenna coupled to the second receiver,

the first and second transmitters connectable at the same time to the same one of either of the first and second antennas.

2. The wireless communication handset of claim 1, the first and second transmitters disconnectable form the same one of the first and second antennas.

3. The wireless communication handset of claim 1, the first receiver is a CDMA receiver, the first transmitter is a CDMA transmitter, the second receiver is a TDMA receiver, the second transmitter is a TDMA transmitter.

4. The wireless communication handset of claim 1, the first antenna is an internal antenna, the first transmitter coupled to the second antenna, the second antenna is an external antenna.

5. The wireless communication handset of claim 1, a switch coupling the first receiver and second transmitters and the second receiver to the same one of the first and the second antennas.

6. The wireless communication handset of claim 1, a processor coupled to the first and second transceivers, a display and input/outputs coupled to the processor.

7. A method in a wireless communications handset having a first transceiver and a second transceiver, comprising:

receiving an uncompressed CDMA signal with a first receiver of the first transceiver;

receiving a second signal with a second receiver of the second transceiver at the same time the first receiver is receiving the uncompressed CDMA signal.

8. The method of claim 7,

receiving the second signal with the second receiver operating in a non-continuous reception mode at the same time the first receiver is receiving the uncompressed CDMA signal.

9. The method of claim 7,

the first receiver is CDMA receiver, the second receiver is a GSM receiver,

receiving a downlink signal with the GSM receiver at the same time the CDMA receiver is receiving the uncompressed CDMA signal.

10. The method of claim 7,

the first receiver is CDMA receiver, the second receiver is a TDMA receiver,

receiving a downlink signal with the TDMA receiver at the same time the CDMA receiver is receiving the uncompressed CDMA signal.

11. The method of claim 7,

receiving a second uncompressed downlink signal with the second receiver operating in a continuous reception mode at the same time the first receiver is receiving the uncompressed CDMA signal.

12. The method of claim 7,

the first receiver coupled to a first antenna,

the second receiver coupled to a second antenna different than the first antenna,

the first transceiver includes a first transmitter, the second transceiver includes a second transmitter,

connecting the first transmitter and the second transmitter to the same one of the first and second antennas at the same time.

13. A method in a wireless communications handset having a first transceiver, the method comprising:

receiving a first signal with a first receiver of the first transceiver,

the first receiver coupled to a first antenna;

transmitting a second signal with a first transmitter of the first transceiver at the same time the first receiver is receiving the first signal,

the first transmitter coupled to a second antenna different than the first antenna,

receiving the first signal with the first receiver includes receiving an uncompressed CDMA downlink signal.

14. A method in a wireless communications device having a first transceiver and a second transceiver, comprising:

transmitting a first signal with a first transmitter of the first transceiver operating in a continuous spread spectrum transmission mode,

the first transmitter coupled to a first antenna;

receiving a second signal with a second receiver of the second transceiver at the same time the first transmitter is transmitting the first signal,

the second receiver coupled to a second antenna different than the first antenna.

15. The method of claim 14,

the first transmitter is CDMA transmitter, the second receiver is a TDMA receiver,

transmitting an uplink signal with the CDMA transmitter;

receiving the second signal with the TDMA receiver at the same time the CDMA transmitter is transmitting the uplink signal.

16. The method of claim 14,

transmitting an uncompressed uplink signal with a first transmitter operating in a continuous transmit mode;

receiving the second signal with the second receiver at the same time the first transmitter is transmitting the uncompressed uplink first signal.

17. The method of claim 14,

the first transmitter is CDMA transmitter, the second receiver is a TDMA receiver,

transmitting an uncompressed uplink signal with the CDMA transmitter;

receiving the second signal with the TDMA receiver at the same time the CDMA transmitter is transmitting the uncompressed uplink signal.

18. A method in a wireless communications device having a first transceiver and a second transceiver, the method comprising:

transmitting with a first transmitter of the first transceiver;

transmitting with a second transmitter of the second transceiver at the same time that the first transmitter is transmitting;

receiving with one of a first receiver of the first transceiver and a second receiver of the second transceiver at the same time the first and second transmitters are transmitting.

19. The method of claim 18, receiving includes receiving an uncompressed continuous signal.

20. A method in a wireless communications device having a first transceiver and a second transceiver, the method comprising:

receiving with a first receiver of the first transceiver;

receiving with a second receiver of the second transceiver at the same time that the first receiver is receiving;

transmitting with one of a first transmitter of the first transceiver and a second transmitter of the second transceiver at the same time the first and second receivers are receiving.

21. The method of claim 20, receiving includes receiving an uncompressed continuous signal.
