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 multi-mode wireless communications handset, comprising:

a first transceiver having a first receiver, the first receiver is a continuous reception mode receiver;

a first antenna coupled to the first receiver;

a second transceiver having a second receiver;

a second antenna coupled to the second receiver,

the multi-mode wireless communication handset for operating the first receiver in a continuous reception mode and for simultaneously operating the second receiver in a receive mode while the first receiver is operating in the continuous reception mode.

2. The multi-mode wireless communications handset of claim 1, the first transceiver having a corresponding first transmitter, the second transceiver having a corresponding second transmitter, the first and second transmitters connectable to one of the first and second antennas.

3. The multi-mode wireless communications handset of claim 2, the first and second transmitters coupled to the second antenna.

4. The multi-mode wireless communication device of claim 1, the first receiver is a CDMA receiver, the first transceiver has a CDMA transmitter.

5. The multi-mode wireless communication handset of claim 2, the first antenna is an internal antenna, the first transmitter coupled to the second antenna, the second antenna is an external antenna.

6. The multi-mode wireless communication handset of claim 4, the second receiver is a TDMA receiver, the second transceiver has a TDMA transmitter, a switch coupling the first and second transmitters and the second receiver to the second antenna.

7. The multi-mode device of claim 1, a processor coupled to the first and second transceivers, a display and input/outputs coupled to the processor, a video device coupled to the processor.

8. A multi-mode wireless communications handset, comprising:

a first transceiver having a first receiver, the first receiver is a continuous reception mode receiver;

a first antenna coupled to the first receiver;

a second transceiver having a second transmitter;

a second antenna coupled to the second transmitter,

the multi-mode wireless communication handset for operating the first receiver in a continuous reception mode and for simultaneously operating the second transmitter in a transmit mode while the first receiver is operating in the continuous reception mode.

9. The multi-mode wireless communication handset of claim 8, the first receiver is CDMA receiver operating in a continuous mode, the second transmitter is a TDMA transmitter that transmits while the CDMA receiver operates in the continuous mode.

10. A method in a multi-mode wireless communications device having a first transceiver and a second transceiver, comprising:

receiving a first signal with a first receiver of the first transceiver operating in a continuous reception mode,

the first receiver coupled to a first antenna;

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

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

11. The method of claim 10,

receiving an uncompressed downlink first signal with the first receiver;

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 downlink first signal.

12. The method of claim 10,

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

receiving an uncompressed downlink signal with the CDMA receiver;

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

13. The method of claim 10,

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

receiving an uncompressed downlink signal with the CDMA receiver;

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

14. The method of claim 10,

receiving a first uncompressed downlink signal with the first receiver;

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 downlink first signal.

15. The method of claim 10, the first transceiver includes a first transmitter, the second transceiver includes a second transmitter, connecting the first transmitter and the second transmitter to one of the first and second antennas.

16. A method in a multi-mode wireless communications device having a first transceiver and a second transceiver, comprising:

receiving a first signal with a first receiver of the first transceiver operating in a continuous reception mode,
