Abstract

Claims (44)

1. An apparatus for use in a mobile device, the apparatus comprising:

a switch configured to switch a transceiver including a transmitter and a first receiver from a first antenna to a second antenna and simultaneously switch a connection of a second receiver from the second antenna to the first antenna; and

at least one processor configured to

receive at least two reception signals from the first and the second receivers;

in response to receiving the at least two reception signals, evaluate a communication link via the first and the second antennae;

based on the evaluation of the communication link, determine that the transmitter is to transmit via the second antenna;

obtain reception parameters used by said first and said second receivers;

cause the switch to switch the transceiver including the transmitter and the first receiver so that the transmitter transmits via the second antenna and to switch the connection of the second receiver from the second antenna to the first antenna; and

exchange reception parameters between the first and second receivers.

2. The apparatus according to claim 1 , wherein the evaluated communication link is an uplink or a downlink.

3. The apparatus according to claim 1 , wherein the reception parameters include downlink analog parts reception parameters or downlink digital parts reception parameters.

4. The apparatus according to claim 1 , wherein the reception parameters include channel estimation parameters or channel interference parameters.

5. The apparatus according to claim 1 , wherein the at least one processor is further configured to adjust at least one of the reception parameters.

6. The apparatus according to claim 5 , wherein the at least one processor is further configured to provide adjustment of the at least one of the reception parameters during switching of the switch.

7. The apparatus according to claim 1 , wherein switching includes switching of analog and digital parameters.

8. The apparatus according to claim 1 , wherein the switch comprises a double pole double throw switch.

9. A device, comprising:

a transceiver;

at least two receivers;

at least two antennae; and

an apparatus according to claim 1 .

10. A method, comprising:

switching a transceiver including a transmitter and a first receiver from a first antenna to a second antenna and simultaneously switching a connection of a second receiver from the second antenna to the first antenna by a switch;

receiving at least two reception signals from the first and the second receivers;

in response to receiving of the at least two reception signals, evaluating a communication link via the first and the second antennae;

based on the evaluation of the communication link, determining that the transmitter is to transmit via the second antenna;

obtaining reception parameters used by said first and said second receivers;

causing the switch to switch the transceiver including the transmitter and the first receiver so that the transmitter transmits via the second antenna and causing the switch to switch the connection of the second receiver from the second antenna to the first antenna; and

exchanging reception parameters between the first and second receivers.

11. The method according to claim 10 , wherein the evaluated communication link is an uplink or a downlink.

12. The method according to claim 10 , wherein the reception parameters include downlink analog parts reception parameters or downlink digital parts reception parameters.

13. The method according to claim 10 , wherein the reception parameters include channel estimation parameters or channel interference parameters.

14. The method according to claim 10 , wherein the method further comprises adjusting of at least one of the reception parameters.

15. The method according to claim 14 , wherein the at least one of the reception parameters is adjusted during switching of the switch.

16. The method according to claim 10 , wherein switching includes switching of analog and digital parameters.

17. The method according to claim 10 , wherein, after switching has been completed, the method comprises continuing receiving the at least two signals via the first and second receivers.

18. A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon, which, when executed by a device, cause the device to perform a method comprising:

switching a transceiver including a transmitter and a first receiver from a first antenna to a second antenna and simultaneously switching a connection of a second receiver from the second antenna to the first antenna by a switch;

receiving at least two reception signals from the first and the second receivers;

in response to receiving of the at least two reception signals, evaluating a communication link via the first and the second antennae;

based on the evaluation of the communication link, determining that the transmitter is to transmit via the second antenna;

obtaining reception parameters used by said first and said second receivers;

causing the switch to switch the transceiver including the transmitter and the first receiver so that the transmitter transmits via the second antenna and causing the switch to switch the connection of the second receiver from the second antenna to the first antenna; and

exchanging reception parameters between the first and second receivers.
